Title: Semiconductor integrated circuit
Inventor: HOJO MASAYASU
IPC: H03K17/04
Filed: 1991-11-05
Abstract: PURPOSE:To reduce power consumption and to quicken an output signal by accelerating a leading and a trailing of a base voltage with respect to each collector current of output NPN transistors(TRs). CONSTITUTION:When an input signal D being at an L level and an inverse of the signal being at an H level change respectively to an H level and an L level, each collector voltage of NPN TRs 6, 5 changes respectively to an L level and an H level. As a result, a collector current IC10 of the NPN TR 10 decreases and a collector current IC11 of the NPNTR11 increases. Thus, a voltage drop DELTAV33 across a resistor 33 whose resistance is very small is small and a voltage drop DELTAV34 across a resistor 34 whose resistance is very small is large. As a result, the fall-down of the base voltage of the NPNTR10 is accelerated and the voltage reaches quickly a low level, and the rising of the base voltage of the NPNTR11 is accelerated and the voltage reaches quickly a high level. Thus, output data X of the NPNTR10 go quickly to an L level from an H level and output data Y of the NPNTR11 go quickly to an H level from an L level.

Title: Method for correcting offset of sensor
Inventor: FUJIWARA YUKIHIRO
IPC: G01D3/028
Filed: 1992-10-02
Abstract: PURPOSE:To pertinently correct the offset of a sensor used for detecting the state of an object to be controlled when the sensor is restarted after the function of the sensor is once stopped. CONSTITUTION:In case the power supply to a sensor device is instantaneously interrupted while an automobile runs, it is discriminated that the automobile is in a stable state from the steering angle of the vehicle being +5 deg. and the output value of a filter circuit 4, namely, the value Ysd of a detected signal is read at the count time T2 of a timer which is, for example, three seconds after the instantaneous interruption. Then an offset correcting process is performing by gradually making an offset correcting value Yod to become nearer and, finally, coincident with the value Ysd of the detected signal. When it is recognized that the sensor outputs a detecting signal while the stable state of the object to be controlled is discriminated, it can be discriminated that the sensor is offset. Therefore, the offset of the sensor can be accurately corrected even when the object to be controlled is operated.
