Abstract: Error correction circuit of a weight sensor for a microwave oven and error correction method correct an error caused by a fluctuation of object and a shaking of a set, sense more accurate  weight, and enhances a reliability of a product. An inverting terminal of the OP-amp(2) is connected to an output terminal through resistors(R1,R2) and diodes(D1,D2), and a non-inverting terminal is grounded via an intermediate terminal of a variable resistor(VR1). The output frequency of the OP-amp(2) is adjusted by a resistor(R3) and a variable resistor(VR1), and is applied to a non-inverting terminal of the OP-amp(3).  The output terminal of the OP-amp(3) composed of a buffer is connected to a base of the transistor(TR1) through a resistor(R4). A square wave is connected to a weight sensing port(INT1) of a microcomputer(1) by an on-off operation of the transistor(TR1), so that an input signal sensing program of the microcomputer(]) is driven by the square wave.

Abstract: 브리더통로의 밸브기구실측에서의 단부를 흡기밸브축과 배기밸브축을 연결하는 선에 따르는 상태로 형성하고, 헤드커버의 윗면에 있어서 최소한 브리더통로 형성쪽 가까운  부분을 상향경사 형상으로 형성하고, 상기한 브리더통로의 단부밸부기구실쪽의 측벽 상기부에 홈형상의 윤활유 취출개구부를 헤드커버의 내면에 따르는 상태로 형성하여 밸브기구실내에서 윤활을 필요로 하는 부분에 윤활유를 확실하게 공급할 수 있게 되므로,  소결이나, 편마모를 방지할 수 있다. 
     특히, 홈형상의 윤활유취출개구부와 아울러, 흡기 및 배기밸브로 향하는 윤활유취출구를 브리더통로의  밸브기구실측 측벽에 개구시킨 경우에는 밸브부분에서의 윤활이 보다 확실히 실행된다.
