Eyes in some parts of Japan seems to be synonymous with quality, but its starting point and compared in terms of domestic components. Some devices with the United States and Europe compared to Japan, the device and it seems not so reliable. In my experience, the Japanese and Japanese cunning device is somewhat similar, and you believe it will be fooled. Following some examples, let us enlighten me on some of the tricky parts of Japan. We all know, the quality of high-power IGBT is not a reliable brand in Japan, Germany, is generally more reliable. There is a Japanese brand (big brand) to sell their IGBT, their product specifications, the bid has a parameter, and their full power load IGBT surface temperature rise is very low, much lower than in Germany. We find it very strange that, logically speaking, Japans technological level is poor...

"Distributors of electronic components" is a term and outdated, the concept of distribution of some enterprises from the early into the supply chain to help the components on hand from the manufacturer shipped to OEM assembly plant operators, in the process of charge a service fee. However, EE in each of the worlds largest distributor of the list ranking, a top company can not be accurately classified as a simple component distributors. Order to survive, promotions, and pulled the thin operating margins, such as Arrow, Avnet, Future, WPG, TTI and PremierFarnell companies will be extended to traditional consignment operation activities, such as design chain, supply chain, logistics, and some packaging design services, OEM business previously conducted in-house business has begun to outsource. Distributors benefit from the increase of prod...

Semiconductor Industry Association (SIA) released the latest report, in August this year, global semiconductor sales reached 21.6 billion year on year increase of 4.5% over the year grew by 4.9% in July. Tight supply of NAND flash memory chip prices and to promote the growth of global semiconductor revenue. ISuppli lowered its 2007 global semiconductor revenue is expected from June is expected to grow by 6% down to 3.5%, and said revenue growth in the second half of the semiconductor can not make up for weak sales in the first half. With the advent season, iSuppli is expected in the second half than the first half of the global semiconductor revenue growth of 10%, three-quarter revenue growth of 8.8% over the second quarter and fourth quarter growth of 4%. This growth trend will continue into next year, is expected in 2008 global semico...

Other semiconductor companies in the financial report for the cold deep anxiety, Chinas largest semiconductor companies in China Resources Microelectronics 6 inches CEO Wang Guoping, a look of yesterday but happy. Because, as of June 30 this year, the companys total revenues surge 25.9% year on year, nearly 17 million. Although the net profit was only 96.12 million Hong Kong dollars, compared with 1.0697 billion over the same period in 2007 decreased, but the sharp drop in the relative counterparts, have been considered bright enough. Restructuring effect the release of Wang Guoping performance due to the above-mentioned six months ago, China Resources Group, a restructuring. March of this year, China Resources Group reorganized its two listed companies, China Resources Logic and CSMCs semiconductor business. Among them, China Resour...

Dresden University of Technology and NovaLED AG has reached in the actual light emitting device 90 lm / W in luminous efficiency, the device brightness of 1000 cd/m2, using the 3D optical extraction system can even reach 124 lm / W. White organic light emitting diodes (OLEDs) are expected to become the next generation of lighting technology, the luminous efficiency compared with traditional light sources may be much higher. White OLEDs function as a unique, dazzling appearance, they will highlight the effects caused by light industry. Such a large area thin flexible light-emitting device, modulation of light and color, can be transparent, even appeared in a variety of sizes and shapes for lighting designers to create a new design space. In the light-emitting efficiency, fluorescent tube light technology for the new threshold set for the...

Chinese Academy of Sciences, Changchun through the transformation of the dye components, has developed a cheaper and efficient dye-sensitized solar cells (DSSC). Dye-sensitized solar cells than conventional silicon solar cells less expensive and more easily printed on a soft surface, but the manufacture of such highly efficient battery needs to be made of precious metal ruthenium dye made with volatile electrolytes. Not long ago, Chinese Academy of Sciences, Changchun should be of the two other materials with researchers developed a new class of dye-sensitized solar cells. New battery not only more efficient, and cheaper and more durable. This technology is the key to the development of new organic dye molecules, the organic dyes are more than the ruthenium compounds, thereby reducing the cost of manufacturing the battery. ...

Although the automotive and heavy industry total energy consumption is considered to be large, but in fact, seemingly clean IT Data Center there is hidden a huge energy consumption. IT data centers consume a lot of energy to serve 25,000 to 35,000 households, which aroused the vigilance of the financial sector, and thus angered environmentalists around the world. Problem is that power transmission efficiency is low, particularly in the power conversion, memory leaks, cooling and power distribution losses and so on. To solve these problems, the worlds top engineers carefully studied the distribution to the server and the load from the point of power for each link in order to reduce power loss. Their work has brought a breakthrough in the architecture is expected to fundamentally change the face of power transmission in the next decade...
