Energy conservation is the main theme of today’s electronics manufacturing, various power management chip in this area are playing an increasingly important role. Many countries use administrative means to even legislation to encourage manufacturers to use in their products, energy-saving technologies fujifilm np-150.

A reference to energy-saving, people tend to think of the machine roar of large factories. In fact, the energy consumption of information technology applications on a global scale is also very striking. In this regard, Linear Technology Power Products Division product marketing manager for TongArmstrong In an interview with “China Electronics News” reporter doing an interview with the image of the note: “to distribute hundreds of millions of YouTube videos, and keep the economy fujifilm np-30 running on server power consumption cases between 2000 and 2005, its consumption has doubled, by 2010 there may be further increased by 75%. In 2005, in order to make such as Google, Microsoft and Yahoo and other Internet giants owned by the world’s data centers of the line state, its power consumption is equivalent to 14 one billion watts of total power generating capacity. Only the United States, the power consumed by server farms will require five large power plants in the above-mentioned operating around the clock. In 2005, the U.S. consumption of the server group reached the United States that year the total electricity generating capacity of 1.2%. this part of the energy utilities in the amount of 2.7 billion. can be seen that the United States alone in terms of server farms, energy consumption fell by 1% at this level would mean an annual saving of 27 fujifilm np-40 million U.S. dollars! ”

Fairchild Semiconductor Technology and Application Support Center Wangrui Xing, vice president of Asia-Pacific region also told reporters: “Improving energy efficiency is the main development trends in the semiconductor market. The constant fuel supply constraints, coupled with mandatory widely used around the sony vgp-bps10/s world related to energy efficiency standards promulgated one after another, are driving the demand for low-power energy-saving new technologies continue to grow. power management IC will continue to use innovative energy-saving ways to deal with these major challenges of energy efficiency, thereby enhancing energy efficiency and space efficiency. “He also pointed out that abandoning the single-phase AC / DC motors and variable speed motor switch, can save up to 40% of energy, while the induction motor into permanent magnet motor, can improve the efficiency of up to 5%. Can be seen that the contribution of power management for energy-saving technology is built on the basis of continual innovation sony vgp-bps10a.

According to market research firm ICInsights new release of the 2008 McClean Report (TheMcCleanReport), IC suppliers rising degree of specialization, have led to abrupt change in the semiconductor industry cycle. Historically, the semiconductor industry, there is a huge cycle, with eight very obvious stage.

IC industry cycle fujifilm np-120

While the shift from one phase to another phase of the usually unpredictable, there are still a number of key factors (such as global GDP growth, electronic system sales growth, IC unit shipment, the semiconductor industry capital spending trends, etc. and so on) can show whether the bottom, or a cycle peak fujifilm np-140.

However, ICInsights that since 2004, these “traditional” industry cycle model has new features. The previous single IC industry cycle, usually about the same time, affecting all of the IC product areas, though some may be different. Now the single-cycle seems to have developed into at least four sub-cycles (ie logic / foundry, MPU, analog and DRAM / flash memory cycle). In addition, DRAM and Flash have their own cycles of change. Between such individual product life cycle independent of each other sony vgp-bps9/b , sony vgp-bps9/s, sometimes with the IC industry, the overall trend in the opposite.

IC industry sub-cycle sony vgp-bps9a

The semiconductor industry from a single large cycle evolved into four sub-cycles, One reason is that IC suppliers, specialization increased. In the past, many large IC suppliers (such as Motorola, Texas Instruments, NEC, etc.) involved in DRAM, logic, analog and MPU and many other product areas. However, most vendors have turned to, or are turning to a more specific product line. Therefore, capital investment and R & D investment are more focused on specific areas of IC products. In addition, each IC product areas (ie, foundry, DRAM, MPU, etc.) are now faced its own unique competitive environment, not necessarily to compete with other product sony vgp-bps9a/b areas as environment.

DRAM market is a good example of sub-cycles. In 2006, DRAM market grew 32%, DRAM average selling price (ASP) rose 13%. In contrast, the overall IC market growth in the year 9%, IC average selling prices fell 8%. In addition, in 2006 the area of DRAM capital spending surge 44% of the overall semiconductor industry capital spending increase (18%) as a whole. Driven by investment in 2007, average selling price of DRAM dropped 39%, while the overall IC industry average selling sony vgp-bpl9 prices fell only 6%.

ICInsights that these sub-cycles will continue to weaken the overall IC industry cycle of intensity change. While in 2006-2007 the area of DRAM and flash memory capital spending significant increase in lack of reason, it is expected that the future of the professional supplier of IC capital spending would be more reasonable to continue to support the sub-cycle mode and ease the overall IC industry cycle fluctuations.

However, ICInsights that each sony vgp-bps10 , sony vgp-bps10/b IC product sub-cycle is still possible at some stage with the transfer, resulting in very weak IC industry growth (decline by 10% or more) or very strong IC industry growth (an increase of 20% or higher).

The casio np-20 battery problem has become so IT vendors and users concerned and worried about the topic, Dell laptop battery explosion last year, Sony recalled a large number of 10 million notebook computer batteries event. This year, mobile phone battery problem once again cause for concern. Previously, mobile phone battery died from the blast users, Nokia has announced the recall of 46 million products from Panasonic cell phone batteries.

Recently received consumer complaints and requests for assistance shows that the battery of security on the topic of the gradual spread to digital cameras.

[Case 1] fast digital camera battery discharge

Increased in several photography forums, the recent emergence of digital camera users about excessive casio np-100 battery discharge complaints.

The user to reflect Mr. Hu, he bought three years ago, M2 Casio digital cameras have recently witnessed the phenomenon of excessive battery discharge, the battery is fully charged stored in the machine where, after three to four days there will be a serious loss of power. “After the battery is full, respectively stored in the machine, and in three or four days time, basically to put replacement in, and sometimes even the machines they can not.”

User complaints, according to the same issues that appear in the Samsung and other brands of digital cameras, “I do not know the battery problem or a digital camera to their problems.”

In response, the State Light Industry Quality Supervision and Test Center minolta np-600 battery-Ru-Kun Lin, Senior Engineer, said this happens, most likely a digital camera itself is a problem.

In general, the battery on the machine where, if not the boot, can not form a power-state, essentially no power loss, it is impossible to place a few days there will be depletion of the phenomenon of electricity; In addition, the poor quality battery materials, batteries, aging is also may result in the battery performance has dropped significantly.

“National Quality Standard for batteries self-discharge provisions are fully charged after the open-circuit state, placed 28 days, the remaining capacity of not less than 80% of the qualified, can be marketed in various brand batteries are subject to national quality testing, and is in line with the national self-discharge standard. However, stored in the machine not boot appeared in such serious cases, the discharge phenomenon can be considered there is a problem. ”

On this issue, the reporter interviewed Casio customer service staff, it said it put the battery inside the camera has to a certain extent even without the use of self-discharge, the case might be the battery itself, it may be a fault occurs inside the camera circuitry, and suggested that journalists will camera and sony np-f970 battery to a repair center for testing.

It is understood that China’s current projects on battery power and discharge detection, are independently tested on the battery, while the discussion of digital cameras there is no national standard in the battery test items and standards, while the digital camera’s own measured, the battery discharge time, there is no standard.

Can not see the battery – aspire 3000 battery

American scientists invented the world’s smallest battery. Its diameter is only 70 microns, and the common cold virus, similar in size and can only be seen under the electron microscope. The battery can be generated within 45 minutes 0.02V voltage. Nuclear batteries

Nuclear batteries is also called “radioisotope batteries.” Isotopes in the decay process of continuous release with a heat-ray, this isotope on the called “radioisotopes.” People through the semiconductor thermoelectric conversion element of these rays into heat energy, it made a nuclear Fujifilm NP-140 battery. Isotopes in the natural decay of the material can be much larger than the average release of energy, but the decay time is very long, therefore, the nuclear battery power big, small size, can be prolonged use. And the decay of isotopes in the energy released when the size, speed, free from the external environment in the temperature, chemical reactions, pressure, electromagnetic fields and other effects. Therefore, it is strong anti-interference and the work is known for accurate and reliable as the battery family in the crowd.

Input and sometimes the existence of the possible impact of high-voltage pulses, as well as interference with a stronger or more stringent EMC requirements of the circuit, the input should be considered together since the resumption of FUSE and the TVS tube a protective VGP-BPS2A, allowing effectively high pulse interference voltage clamp in the module can withstand value range, and also increased the output common-mode choke coil, or FILTER2 Safety capacitor. Figure 3 shows:

Figure 3 DC / DC interference in the demanding application of occasions

But to note that the choice for the TVS tube must be based on various occasions VGP-BPS10, to select the appropriate power and voltage values, so as to effectively prevent the strong interference caused by huge and sudden impact. Such as the TVS tube voltage chosen too low will affect the normal operation of the module, the voltage value of the election are too high, turn the power module and will not achieve security after the circuit-level role. In addition, for long-term pulse shocks, but also consider the enduring grip over-voltage over-current circuit protection. Safety Capacitor C3 values suggested the use of 47-100pF, pressure values should be chosen ≥ isolation voltage (1000,3000,6000 VDC).

Hydrogen fuel cell motorcycle exhibition will serve green Olympic Games debut for VGP-BPS9 B , VGP-BPS9 S

Olympic Motor Show debut Environment

Yesterday, the Tenth International Environmental Protection Exhibition at the International Exhibition Center. One by the Italian design and manufacture of “zero emissions” electric motorcycle Olympic Games attracted the attention of many viewers. Bike’s hydrogen fuel cells will not cause any pollution to the environment NP-20, will apply to the Olympic athletes during the transport of goods and transportation.

Holiday trips, how is it got a Digital Camcorder Battery, flashlight, therefore, the battery will become an essential travel items. However, if you do not pay attention, you bring the battery will be a huge source of pollution.

This reporter learned that the battery pollution is mainly concentrated in a small amount of heavy metals contained in them, such as lead, mercury, cadmium. Waste batteries after a long mechanical wear and corrosion, its internal heavy metals and acid-base and so will be leaked into the soil or water, and through various channels into the human food chain. Scientific research shows that a 1 has mercury batteries rot in the ground can make 1 square meter of land completely lost agricultural use value; a coin cell battery can make 600 tons of water unfit for drinking. More seriously, the battery has a cycle of pollution, long hidden major characteristics, its potential harm is very serious, improper handling can also cause secondary Digital Camera Battery pollution.

To really green tourism, reduce pollution, the first step is to choose environmentally friendly low-mercury batteries. At present, sales at home and abroad batteries, are required to mark mercury (mercury content in batteries labeling methods, environmental labeling different battery manufacturers, the “low mercury”, “No Mercury” and so in several ways). Consumers to buy the battery, just look at mercury in batteries, we can know whether the battery of environmental protection.

In 2006, AQSIQ right battery product quality supervision and spot checks, with a pass rate of 74.5%. Experts note that the purchase of environmentally friendly batteries, first of all, we should try to choose a “National Inspection-free”, “Chinese famous brand” logo and the local brand-name batteries battery products; secondly, also according to the requirements of electrical appliances, select the appropriate battery type and specification size, and power apparatus according to the size and characteristics of the power to buy batteries for electric appliances; In addition, consumers should pay attention to the battery symbol, the battery should be marked with the production mark the make, Casio Battery polarity, the battery model , nominal voltage, trademarks, etc.; sales package on the site should be in Chinese, manufacturing date and shelf-life or shelf life of the deadline marked the implementation of the standard number, purchase of alkaline zinc-manganese battery model should also look at whether or ALKALINE or LR words.

Green battery while lower than mercury, but if you use a large quantity, or pollute the environment. Therefore, the more environmentally friendly way is to choose reusable rechargeable batteries. Present, there is the more common rechargeable batteries are nickel-hydrogen batteries, nickel cadmium batteries and lithium batteries. Ni-MH battery cycle life is characterized by long, theoretical 2000 ~ 4000 times the cycle life; nickel-cadmium batteries of high energy density, environmental protection and good, and basically eliminates the “memory effect”; lithium battery is the exclusive digital products battery, one can randomly change its shape, almost no memory effect, and use a long time, but the price is relatively expensive.

At present, a very respected environmental organizations at home and abroad to use rechargeable batteries. Experts point out that when you purchase rechargeable batteries, in addition to the brand, it can also weigh about weight. Generally heavier weight, the better the quality. The charger must be purchased buy brand-name products, and if I get quick charger, be sure to understand whether the automatic power-off function. In addition, experts also cautioned that bought back ordinary rechargeable Casio NP-100 battery power is low, the first charge must be sufficient. Ni-MH battery charging time are generally more than 16 hours. To achieve best results, generally more than 3 times repeated charge-discharge can. In addition, the battery in use after three rounds, the best place to find the opportunity to complete power to make further charge, so as not there is residual power in the battery when the repeated charge, this will shorten the battery life.

Hydrogen: New Energy Star of Hope

The northwest corner of Beijing Zhongguancun Science and Technology Park, Yongfeng High-tech industrial base, China’s first in order to promote comprehensive utilization of hydrogen energy, hydrogen energy education and science, hydrogen energy research and promotion of new results demonstrate for the purpose of the demonstration garden —-” Beijing Hydrogen Demonstration Park “under construction. Not long ago, a project of the demonstration garden officially put into use. Expert evaluation, the move will promote China’s hydrogen and hydrogen vehicle Casio NP-20 technology development, promoting the industrialization of hydrogen cars and played an active role.

Hydrogen with its clean, safe and efficient characteristics are more and more attention. Many scientists believe that hydrogen in this century may become the world’s new energy arena, an important “Star of Hope.” It is optimistic about the hydrogen of the “star” potential for scientific research around the world have increased the strength and financial investment in hydrogen energy development and use of a study.

The new energy efficient and clean

Hydrogen is a clean and efficient secondary energy, has many unique advantages: First, the hydrogen source of a wide range, from fossil energy, nuclear energy, renewable energy in the extraction, is conducive to break away from dependence on oil; Second, hydrogen can serve as fuel in conventional combustion equipment for energy conversion, easy compatibility with existing energy systems; third, hydrogen fuel cell technology through the transformation of energy conversion than the use of more Casio NP-30, Casio NP-40 efficient heat engines, and no environmental pollution; In addition, the Hydrogen can be stored, you can try it with the power complementary.

The use of hydrogen is not a new phenomenon. In China’s aerospace field, “missiles plus one satellite” in the liquid hydrogen oxygen research is the use of hydrogen energy, but all these are high-tech areas, away from our lives is also a bit far. In the civilian industry, fuel cell technology as an ideal hydrogen conversion device, in recent years has developed rapidly.

The principle of hydrogen fuel cells is to use hydrogen as active material, and oxygen (or air in oxygen) electrochemical reaction occurs, in a clean state to obtain direct current energy plant.

Automotive Safety and Energy, Tsinghua University State Key Laboratory of Dr. Wang Hewu told reporters that at present, the use of hydrogen fuel cell is the best technology, with no pollution, high efficiency, wide application, no noise, able to continuously work and the building blocks of assembly advantages. The use of hydrogen fuel cell vehicle emissions out of water, can be truly zero emissions.

However, hydrogen can really widely used, hydrogen extraction, storage and transmission technologies such as research and development, is very important. At present, hydrogen Preparation of primary energy consumption caused by high costs, while the hydrogen storage and delivery has not a good way Casio NP-L7, the use of metal hydride hydrogen storage rate is too low, high-pressure hydrogen storage tank are too high energy consumption.

Therefore, the experts believe that to successfully promote hydrogen and fuel cells in production, from hydrogen production, storage, transportation-related infrastructure and industrial system, as well as the establishment of standards, must go through a long and arduous scientific and technological research.
