摘要： PROBLEM TO BE SOLVED: To enable an inspector to easily and surely check the confirmation of the alarm operation of a CO sensor without using any specific jig by providing such a notification means that uses the blinking of an LED or the synthetic sounds transmitted through a speaker. SOLUTION: A CO sensor and a city gas sensor are driven by the outputs (a) and (b) received from a microcomputer and the pulses of cycle 1ms. The microcomputer has a timer using a ceramic oscillator to control the time intervals of both high and low temperature operations of the CO sensor. The outputs (c) and (d) of the microcomputer are equal to the signals which are sent to an LED and an amplifier respectively from the microcomputer in 10 seconds (t2 ) set before the output monitoring of the CO sensor. The LED is instantaneously turned off by the signal received from the microcomputer, and a speaker transmits the synthetic sounds by the signal that is received by the amplifier from the microcomputer. As a result, the CO detection timing of the CO sensor can be known.

摘要： PROBLEM TO BE SOLVED: To provide a contact combustion type composite gas detector improved in gas selectivity and capable of selectively detecting methane gas and CO gas. SOLUTION: A contact combustion type composite gas detector is equipped with a bridge circuit B1 having an urban gas sensor incorporated in the branch piece thereof, a bridge circuit B2 having a carbon monoxide gas sensor incorporated in the branch piece thereof, the control part N driving both bridge circuits B1, B2 and an operation part S digitally operating the outputs of both bridge circuits B1, B2 to output the same. Either one of urban gas sensor and the CO gas sensor is subjected to two temp. cycle operations of low and high temps. and an operation coefficient is set so as to equalize the outputs to hydrogen gas of both bridge circuits outputs between the gas sensors or between two temps. of the gas sensors. By this constitution, the outputs to hydrogen gas are set off by using the operation coefficient to prevent the outputs to the CO gas from receiving the effect of the hydrogen gas.

摘要： PROBLEM TO BE SOLVED: To inspect interlocking operation of a gas meter in a state that an inspection gas use amount is suppressed without waiting a delay time.SOLUTION: When long-time (3 seconds) pressing operation of a switch is performed during gas leakage detection (YES in S4, S5), this gas leakage alarm starts external output for making the gas meter perform the interlocking operation and comes into an interlocking confirmation operation mode (S6). The gas leakage alarm continues the external output regardless of presence/absence of gas leakage during the mode. Thereafter, though the mode is released (S11 or S12) when operation to turn off the switch is performed (S1, NO), the external output is continued when it is during the gas leakage detection (S10, YES and S12 execution). That is, when it is as the switch is turned on, the external output is continued regardless of presence/absence of a gas.
