According to sources, the number of Windows 8 applications in the Microsoft Windows Store has exceeded 50,000, a total of 50304 models. Microsoft will reward developers.
It is understood that Microsoft had promised to pay $100 in cash awards to application developers on the Windows 8 and Windows Phone 8 platforms. As a result, the number of Windows 8 applications will continue to rise rapidly under this clause.
It is reported that the number of Microsoft Windows Phone platform applications on the smartphone side also reached 130,000 at the end of last month. In addition, the number of Windows 8 applications in the Microsoft Windows Store has reached 50,304, of which X86, X64 are used on the traditional PC desktop, and Windows RT is based on the ARM architecture, which is used in tablet computers.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
