Granted: 2000-05-15
Abstract: PURPOSE: A hydroplaning removing system for a vehicle maintains the braking force and the steer-ability of the vehicle even on raining by reducing hydroplaning, thereby is preventing a safety accident. CONSTITUTION: A hydroplaning removing device for a vehicle comprises an operation switch(1), a control unit(3), a hydroplaning perceiving sensor, a power generator(7) and an auxiliary rotation wheel portion(9). The operation switch(1) is operated by a driver. The hydroplaning perceiving sensor inputs the signal of the measured value of a hydroplaning formed on a road surface on raining to the control unit(3). The auxiliary rotation wheel portion(9) removes the hydroplaning formed on the road surface by being moved vertically by the power of the power generator(7). Thus, the loss of the braking force of a vehicle is prevented, thereby securing passengers' safety.

Abstract: 기입 및 독출동작시 필요한 핀수를 감소시킬 수 있는 프로그래머블 마이크로 콘트롤러와 이의 데이터 기입방법 및 데이터 독출방법이 개시된다. 상기 데이터 기입방법 및 데이터 독출방법을 수행하는 상기 프로그래머블 마이크로 콘트롤러는, 기입동작시 외부에서 입출력핀을 통해 인가되는 시어리얼 데이터를 클락핀을 통해 인가되는 쉬프트 클락에 동기시켜 시어리얼하게 수신하여 패러렐하게 상기 메모리부에 전달하고, 독출동작시 상기 메모리부로부터 패러렐하게 전달되는 데이터를 상기 쉬프트 클락에 동기시켜 상기 입출력핀을 통해 시어리얼하게 외부로 송신하는 시어리얼 인터페이스 회로를 구비하는 것을 특징으로한다. 따라서 상기 프로그래머블 마이크로 콘트롤러는, 상기 시어리얼 인터페이스 회로를 구비함으로써 기입 및 독출동작시 하나의 데이터 입출력핀과 하나의 클락핀만이 필요하므로 핀수가 감소된다.

Abstract: PURPOSE: A method for manufacturing a silicon gate electrode of a MOS semiconductor device is provided to improve the electrical characteristic of a semiconductor device by preventing a gate oxide layer from being broken. CONSTITUTION: An active area is defined in a semiconductor substrate(11). Then, a gate oxide layer(13) is formed on the semiconductor substrate(11). After that, an amorphous silicon thin film(14) and a polysilicon thin film(15) are alternatively and sequentially formed on the semiconductor substrate(11) by means of an in-situ process. Then, a silicon thin film(20) having multi-layer structure is formed on the semiconductor substrate(11) by patterning the amorphous silicon thin film(14) and the polysilicon thin film(15). Impurities are doped into the silicon thin film(20). Then, an annealing process is carried out with respect to the silicon thin film(20) thereby reducing the resistance and obtaining a crystal structure of the silicon thin film(20) consisting of a columnar structure and a dendrite structure.
