Title:
TIME RECORDING DEVICE
Document Type and Number:
Japanese Patent JPH01113695
Kind Code:
A
Abstract:
PURPOSE:To record an elapsing time without utilizing an expensive equipment, by generating control signals with a predetermined time interval and then by melting away one of fuses for each output of the control signal sequentially from the commencement time of an accident recording. CONSTITUTION:For such a case that an accident occurs at an inflator 7 or a sensor 8-11 of a screw protection device 1, if the operation of the device is continued for a predetermined period, a control signal from an output means 3 is fed to a control means 5 with a predetermined time interval. Each time the control signal is fed to the control means 5, each of fuses 4a-4n in a fuse unit 4 is fused sequentially. Therefore, without utilizing an expensive equipment such as a non-volatile memory, a recording of an elapsing time from an detection time of the accident can be obtained by accumulation of the time intervals based on the number of the molten fuses 4a-4n.
