A key input device comprises a dome sheet provided over a base plate and having a plurality of dome portions, and a plurality of manual keys disposed above the dome sheet for depressing the respective dome portions. Each of the dome portions is elastically restorably inverted by being depressed by the corresponding manual key to close contacts. The dome sheet has a flat sheet portion formed around the dome portions and comprising an inner region extending inwardly of dome portions to be selectively depressed by a seesaw key , and an outer region extending outwardly of the dome portion . A spacer sheet is interposed between the base plate and the dome sheet to thereby position the inner region of the flat sheet portion of the dome sheet at a lower level than the outer region . Accordingly, key contacts can be reliably closed by the seesaw key

Key input device

In the level shift circuit, the input unit is connected to the first power source and the ground, and the output unit is connected to the second power source and the ground. The input unit receives a signal changing between the ground potential and the power supply potential of the first power source and outputs the signal. The output unit receives this signal from the input unit, and voltage-shifts it into a signal changing between the ground potential and the power supply potential of the second power source. The output unit includes an interruption circuit which cuts off the current path from the second power source to the ground via the output unit. The output unit also includes a potential detection circuit which detects the time when the first power source is interrupted, and outputs a control signal. When the first power source is interrupted, the control signal of the potential detection circuit causes the interruption circuit to cut off the current path. As a result, it is secured to prevent the through current from flowing to the output unit in the power down mode.

Level shift circuit

In order to reduce power consumption, a power supply for a digital circuit portion is shut off, so that the output voltage of the power supply becomes the zero level. A CMOS (complementary metal oxide semiconductor) inverter has a P-channel FET (field effect transistor) with a gate electrode formed of P-type polysilicon. A source electrode of the P-channel FET is connected to the power supply and a back gate electrode of the P-channel FET is in direct connection with the aforesaid source electrode. The P-channel FET is placed in a state of not functioning as a transistor when the power supply is shut off in a low power consumption mode. However, in order to prevent the P-channel FET from undergoing characteristic degradation in that mode, there is the provision of a pull-down switch capable of fixing, in the mode, the voltage of the gate electrode of the P-channel FET at the zero level.

CMOS semiconductor integrated circuit

An apparatus detects a collision according to a signal from an acceleration sensor 1, to deploy an air bag of a car. The apparatus prevents an erroneous deployment of the air bag when the car is driving along a rough road. The apparatus employs two deceleration thresholds for a signal from the acceleration sensor 1. The apparatus has a signal integrator 3 that integrates an area of the signal defined by the thresholds as well as an acceleration area of the same signal. The apparatus has a determination unit 4 that determines a collision if an integral provided by the signal integrator 3 is above a value corresponding to an OFF collision that requires no deployment of the air bag.

Apparatus for determining collision for air bag

An electrical control apparatus for the air bag system capable of inhibiting the diagnosis of back-up capacitors when a diagnosing routine is initiated by an extraneous noise. In a main routine executed by a microcomputer provided in an electrical control apparatus for an air-bag system, data stored in a specific address of a volatile memory is read out, and it is determined whether or not its value is the same as a fixed value. If the result is affirmative, it is determined that the main routine is started by an extraneous noise, an ignition flag IG is reset, and the diagnosis of the back-up capacitors is inhibited. On the other hand, if the data does not have the same value as the fixed value, it is determined that the ignition switch is turned on again after it has been turned off, the IG is set, and the diagnosis for back-up capacitors is carried out.
