The children's day is coming, for this festival we will say something about the childhood. Toys and games are everyone's most precious childhood memories, which carrying childhood dream and memory. Looking back, what are the post 70 and 80 playing? Nowadays, what are the post-90 and post-00 else playing? When the toys and games evolved from a group to individual, from educational to "a joke", his childhood in social progress, what have they lost or got?
The Electronic Age
1. PC Games
Freud said that childhood decision to human life, according to this theory, when you see children are playing CS game, carrying AK47 in the cyber bar, there must be some chilling. The emergence of computer games dominated the toy world, the lack of social life making the child are more likely to experience the virtual world. In computer games, they are master, be free to decide the next step in the direction, do not listen to adult pointing and instilled in them do not want to hear the big stuff.
2. Toys
The appearance of toys upset the pure partnership in fathers' eyes. Each child in the face of another child had to beware of "would he fix me?” The children who have toys, then can't wait to get a small "cut" to their partners. Prank became a professional level of things.
3. Electronic Pets
Compared to real pets, electronic pets are more convenient to carry, better to care and will not stain carpets and sofas. More importantly, do not bear too much responsibility. If raising dead, but also just restart. On the surface, the benefits of electronic pets are more, but it allows the city's children lost their respect for life, lost the natural exchange opportunities with animals.

However, the oversea markets are quite potential and any company, who intends to develop its company further, should pay enough attention to these markets. Nevertheless, although many companies realize the potential oversea markets, they could not find some great sales, which is really a big trouble for them to go forward. Therefore, in order to help suppliers in HQEW.net to handle this predicament, IBD of HQEW.net held its first job fair to try to recruit some capable sales for them.
On that day, on the one hand, many interviewees who are good at international business came to HQEW.net, F/r 7, 2# Building, Huaqiang Holdings Group. On the other hand, the representatives of some companies, such as, Shuangzhi (HK) Electronic Co., Limited, Shenzhen Honton Electronics Technology Co., Limited and so on, had paid a visit to our company as well. The interview of this fair mainly contains several parts, such as, group interview and one to one interview. In the group interview, the interviewees should display themselves to all interviewers. And then, the representatives of the suppliers would pick out their favorite interviewees to interview them separately. This fair held very successfully and after the rounds of interviews, both interviewers and interviewees showed their satisfaction to this fair as well as our company.
Keeping the faith, “customers first”, in mind, IBD of HQEW.net held this job fair to help suppliers in HQEW.net find the excellent sales and further promote the development of their international business. It is turned out that both interviewers and interviewees were quite satisfied with this movement and they hoped this movement would be held further in the future. Meanwhile, HQEW.net was so happy for the ending and expressed that the company would continue to concern for the customers and chair this kind of movement henceforward.

Electronic Components Prices in 2011—Rise or Not?
Because of the increasing costs of labor and raw materials, it is expected that some electronic components will rise in their prices in some degrees. Based on the market survey, inductors and electrolytic capacitors belong to these electronic components as well.
Actually, manufacturers do not insist that the prices of all electronic components will go up in 2011, for example, OVP parts. Lots of manufacturers believe that the price of OVP parts will be stable and will not rise obviously in this year. By contrast, as for aluminum electrolytic capacitors market, some experts of IC components industry, for example, Liu Quanwang, aluminum electrolytic capacitors product marketing director of TDK-EPC group member, Greater China EPCOS, suggest that the price of aluminum electrolytic capacitors would develop in the rising trend. The reason for this phenomenon of electronic components market is the rising cost of some raw materials and energy costs. Moreover, it needs to point out that the raw materials above refer to aluminum and papers and so on; while, energy costs consist of the main production costs of anodic aluminum foil.
At the same time, the costs of labor in China rise rapidly as well and some specialists predict the increasing trend of the cost of Chinese labor will continue in the coming years. What’s more, tantalum electrolytic capacitors’ situation is similar to aluminum electrolytic capacitors’ which has been introduced above. According to the above analysis, some but not all electronic components will rise in their prices in 2011.

Japan Earthquake Affected International Manufacturing Supply Chain – iPad2 Has Cut
Reloaded from http://www.partsparty.com/?p=449
Japan’s eastern coast from the strong earthquake occurred in 9 of more than half a month has passed, but the earthquake damage is still spreading, equipment damage and power shortage on the Japanese company to resume production quickly create great obstacles, their impact is also important to quickly spread to Japan link point of the global manufacturing chain.
Japan’s earthquake disaster caused damage to a number of business equipment, coupled with Japan’s plans to take measures to deal a serious setback power supply capacity, difficulties encountered enterprises to resume production. Components can not deliver on time, assembled into finished products without straw, not only affect Japan’s domestic production, which is also 10% of the key components imported from Japan, the Japanese rely on overseas factories facing difficulties with the Japanese companies have supply and demand of many international companies are inevitable compromised.
Globalization, manufacturing supply chain can be said to affect the situation as a whole. For example, Japan is the world’s automobile industry an important part of the industry chain, Europe, Asia, auto makers had felt from the moment “in Japan” cut and cut a “shock.”
According to U.S. research firm IHS25 released survey data, due to sharp drop in production in Japan, imported from Japan on time delivery of parts can not be expected worldwide vehicle production cut to 600,000 by the end of March. If Japan can not resume normal production, two months after the earthquake, the worldwide auto production could fall 30%.
According to Japan, “Asahi Shimbun” reported that due to import spare parts from Japan in trouble, General Motors had to face some knock-on effect. Its located in a small Louisiana truck plant 21, were forced to stop, and then provide them a New York engine plant had to lay off 59 people. General Motors in Spain and Germany also temporarily suspend part of the plant.
According to Kyodo News and the “Japanese Economic News” and other media reports, Ford Motor Company has a full cessation of 25 black and red passenger car orders because of difficulties in paint imported from Japan. As imports from the electronic components Hitachi be obstacles, the French PSA Peugeot Citroen Group in the European diesel engine production line has also been directly affected.
Japan’s neighbors South Korea of Japan’s imports in 2010 amounted to 64.3 billion U.S. dollars, mainly imported parts and raw materials. Since the transmission from Japan stocks dropped, Renault Samsung Motors plant in Busan, the date of cancellation from 18 to work overtime, Saturdays production.
Affected by the earthquake in Japan as China’s Dongfeng Motor Co., Ltd. Dongfeng Nissan Passenger Vehicle Company is currently declining dramatically. 26 factories located in Xiangfan, the production plan has been arranged by one-third less than usual, into a semi-shutdown state. After the big earthquakes in Japan, as Japanese domestic production of engines, transmissions and other key components are not on product supply, Dongfeng Nissan to rely on inventory to maintain production.
In addition to the automotive industry, the Japanese earthquake on the impact of other manufacturing supply chains are gradually becoming apparent. According to “Asahi Shimbun” reported that the U.S. Apple Tablet PC iPad2 at least 5 manufacturers of electronic components from Japan, affected by the earthquake is difficult to deliver on time, especially its display only the products imported from Japan, so the possibility of production cuts great.
In addition, the world’s largest mobile phone manufacturer Nokia is due to the shortage of spare parts imported from Japan, part of the production line may be suspended production. Hyundai Heavy Industries, Samsung Heavy Industries shipbuilding steel plate needed, in the Japanese import “without food” situation, domestic steel companies have requested an emergency increase to meet their urgent needs.

Application Information of UCC3808
A 200-kHz push-pull application circuit with a full wave rectifier is shown in Figure 2. The output, VO, provides 5 V at 75 W maximum and is electrically isolated from the input. Since the UCC3808 is a peak current mode controller the 2N2222A emitter following amplifier (buffers the CT waveform) provides slope compensation which is necessary for duty ratios greater than 50%. Capacitor decoupling is very important with a single ground IC controller, and a 1 μF is suggested as close to the IC as possible. The controller supply is a series RC for start-up, paralleled with a bias winding on the output inductor used in steady state operation.
Isolation is provided by an optocoupler with regulation done on the secondary side using the UC3965 Precision. Reference with Low Offset Error Amplifier. Small signal compensation with tight voltage regulation is achieved using this part on the secondary side. Many choices exist for the output inductor depending on cost, volume, and mechanicall strength. Several design options are iron powder, molypermalloy (MPP), or a ferrite core with an air gap as shown here. The main power transformer is a low profile design, EFD size 25, using Magnetics Inc. P material which is a good choice at this frequency and temperature. The input voltage may range from 36 V dc to 72 V dc.

AD620A - Low Cost, Low Power Instrumentation Amplifier - Analog Devices
The AD620A is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 1000. Furthermore, the AD620A features 8-lead SOIC and DIP packaging that is smaller than discrete designs, and offers lower power (only 1.3 mA max supply current), making it a good fit for battery powered, portable (or remote) applications.
The AD620A, with its high accuracy of 40 ppm maximum nonlinearity, low offset voltage of 50 mV max and offset drift of 0.6 mV/°C max, is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces. Furthermore, the low noise, low input bias current, and low power of the AD620A make it well suited for medical applications such as ECG and noninvasive blood pressure monitors.
The low input bias current of 1.0 nA max is made possible with the use of Superbeta processing in the input stage. The AD620A works well as a preamplifier due to its low input voltage noise of 9 nV/ÖHz at 1 kHz, 0.28 mV p-p in the 0.1 Hz to 10 Hz band, 0.1 pA/ÖHz input current noise. Also, the AD620A is well suited for multiplexed applications with its settling time of 15 ms to 0.01% and its cost is low enough to enable designs with one inamp per channel.

SAA8112HL - Optical black processing
SAA8112HL has optical black processing function.
The first processing block of the SAA8112HL is a digital clamp . It is used to align the optical black level to zero or to any arbitrary value.
When the digital clamp is set active, the average value of the black is measured in the programmable optical black window and then subtracted from the input signal. A separate measurement is done for odd and even pixels and for odd and even frames.
When the digital clamp is set inactive, it is possible to subtract a fixed value from the incoming data stream. A different value can be programmed for odd/even pixels, odd/even fields and odd/even lines.
The optical black window has a fixed size of 16 pixels (horizontally) by 128 (vertically), although the position of this window is fully programmable.

The Description of SN74LVC2G125
SN74LVC2G125 is an electronic component that is a dual bus buffer gate, designed for 1.65-V to 5.5-V VCC operation. This device features dual line drivers with 3-state outputs. The outputs are disabled when the associated output-enable (OE) input is high.
NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.

Dollar Rate - Affect You?
“The drop in the dollar exchange rate has ceased impacting us. It has already passed to another stage, to where it is killing us, choking. Even still, they raised our taxes, the municipal tax (arnona) soared, fuel rose 7%, and if all that wasn’t enough, now they throw a raise in the minimum wage at us. They’re killing us slowly, and the situation with the dollar doesn’t help the health of any manufacturer.” Electronic components manufacturer RH Technologies chairman Yakov Rosenberg told “Globes” this morning.
But Rosenberg added, “We are continuing to battle - but there is nowhere anymore. We are beginning to take into calculation possible cuts to the workforce, because there is nothing to do - sometimes it is better to cut off a leg in order to save the rest of the body. We need a damage assessment in light of the economic decrees which have frequently fallen on us recently.”
