Title: Semiconductor device
Inventor: MUTO KAZUHIKO
IPC: H01L31/10
Filed: 1986-02-28
Abstract: PURPOSE:To avoid invasion of a leakage current and an external current and so forth and improve capability of signal transmission and signal processing by a method wherein guard means are provided above or/and below a signal line on a substrate and the potential of the guard means is set at the value close to the potential of the signal line. CONSTITUTION:The cathode 2 and anode 3 of a photodiode 1 are connected to the non-inversion terminal and inversion terminal of an operational amplifier 4 respectively. Guard means 6 and 7 are provided on both sides of a signal line 5 and a reference voltage Vc is applied to the respective guard means. In the constitution like this, when a light enters the photodiode 1, a photocurrent is applied to a logarithmic diode 8 through the signal line 5 and a voltage obtained by logarithmic conversion of the photocurrent appears at the output terminal of the operational amplifier 4. At that time, even if the photocurrent is very small, the invasion of a leakage current and an external current can be avoided. Therefore, the output voltage which corresponds to the incident luminous power accurately appears at the output terminal of the operational amplifier 4 so that accuracy of signal processing can be improved.

Abstract: PURPOSE:To attain early countermeature to a fault by providing a detection/display function to a connector part to inform a faulty state such as disconnection of a connector or power failure of equipment to an opposite device. CONSTITUTION:Although no information is fed to an opposite microprocessor MPU2 because a microprocessor MPU1 is stopped if a power supply section PW1 is disconnected, a power supply supervisory section 34 and a check section 32 are activated while receiving power supply from a small sized battery 36, then the check section 32 transmits a power failure signal via a signal line 44, a check section 33 supplies a reset signal to the microprocessor MPU2 by using the received power failure signal to make the received data ineffective. Since the output voltages of power supply sections PW1, PW2 are not fed to power supply supervisory sections 34, 35 if a cable connector is disconnected, the processing is conducted similarly as that of power failure.
