I. Chinese semiconductor device model naming method
The model of a semiconductor device consists of five parts (the models of the Field Effect Device, special semiconductor device, composite tube, pin tube, and laser device are only part 3, 4, and 5. The five parts have the following meanings:
Part 1: digital representation of the Number of valid electrodes for a semiconductor device. 2-diode, 3-Transistor
Part 2: Material and polarity of the semiconductor device are represented by Chinese pinyi

How transistors work
Transistor is a current amplification device, there are three poles, respectively, called Collector C, base B, emission pole E. Divided into NPN and PnP two kinds.We only use the NPN transistor's common emitter amplification circuit as an example to illustrate the fundamentals of the transistor amplification circuit.

Kernel threadSometimes, when your device needs periodic check, you need to create your own kernel mode thread.

after the graphics driver is loaded, it crashes when it enters Windows. You can replace the graphics card of another model. After loading the driver, insert the old graphics card to solve the problem. If such a fault cannot be solved, it indicates a registry fault. You can recover the registry or reinstall the operating system.
