Title: Gas leak alarm
Inventor: YAMASHITA RYOHEI
IPC: G08B21/00
Filed: 1989-03-07
Abstract: PURPOSE:To hold the gas concentration for raising an alarm roughly constant and to obtain a gas leak alarm having high reliability by correcting a reference value for raising an alarm, in the case when a resistance value of a gas sensor changes with the lapse of time. CONSTITUTION:An output value of a gas sensor when there is no gas leakage after the circuit is stabilized after a prescribed time after turning on power sources 6, 13 is stored in advance as a sensor reference point in a memory of a microcomputer 17. Subsequently, it is set as a '0' point of that time point and a value of this '0' point is monitored. When the value of this '0' point is varied, a timer is started from that time point, and unless its value is varied exceeding a period set in advance (for instance, one month or longer), its value is reregistered as a '0' point. Simultaneously, a difference between the '0' point of the previous time and the '0' point of this time is derived, it is subtracted from an alarm reference value for raising an alarm set in advance, and its value is set as a new reference value for raising an alarm.

Filed: 1988-03-10
Abstract: PURPOSE:To obtain the phase difference detecting device which can performs correlation arithmetic operation for phase difference detection at a high speed with high accuracy by performing the correlation arithmetic operation with an analog signal which is generated by photoelectric conversion as it is and converting the correlation value of the arithmetic result into an analog signal. CONSTITUTION:A reference image sensor 13 and a reference image sensor 14 photodetect a couple of optical images of a subject and convert them photoelectrically to output an analog electric signal R(t) generated by the photoelectric conversion corresponding to one optical image and an analog electric signal B(t) corresponding to the other optical image in order without destruction so that they are made out of phase with each other by a specific period. The couple of analog signals are led to an analog correlation computing element 15 to perform analog correlation arithmetic, and the correlation value which is the arithmetic result is converted by an A/D converter 16 into a digital signal. The arithmetic processing is therefore speeded up and no round error is generated unlike a case where digital correlation arithmetic is performed after conversion into digital signals, so the high-accuracy arithmetic result is obtained.
