摘要： PROBLEM TO BE SOLVED: To reduce a waiting time due to fatigue of a gas sensor. SOLUTION: In a leak detector, specimen gas and background gas are alternately supplied to first and second gas sensors, and the gas flow rates of the specimen gas and the background gas are set to be constant and to be equal to each other. When gas leakage is detected from an output of the gas sensor contacting with the specimen gas, and the output of the gas sensor is equal to or exceeds a threshold for a prescribed time or longer continuously, flow passages of the specimen gas and the background gas are switched.

摘要： PROBLEM TO BE SOLVED: To provide a device capable of generating simply reliable zero-gas air.
SOLUTION: A permeable metal partition 8 is set inside a container 4, and an adsorbent 6 is filled outside. The air in an inside space 10 is purified by the adsorbent 6, and a sensor probe 12 is inserted, and the air is used as clean air for zero-point calibration. Though a granular active carbon is used for the adsorbent 6 in an execution sample, its shape can be selected optionally, for example, a sheet shape. The metal partition 8 may be formed by sticking a wire mesh for preventing invasion of fine powder of the adsorbent 6 or a gas permeable membrane such as a polytetrafluoroethylene film or the like onto a metal cylinder provided with many small holes.

摘要： PROBLEM TO BE SOLVED: To prevent a gas sensor from being poisoned or a false report from being sent by gas being generated by a space for a supplementary circuit.
SOLUTION: In a gas detector, a middle space 32 is provided between a small chamber 14 for accommodating a gas sensor 6 and the space 26 for a supplementary circuit. An air vent 34 is provided at the middle space 32 so that a surrounding atmosphere blows through, thus preventing gas from the space 26 for a supplementary circuit from reaching the small chamber 14, and hence preventing the gas sensor 6 from being poisoned or a false report from being sent by gas being generated from a printed circuit board 20.

摘要： PROBLEM TO BE SOLVED: To provide a gas detection apparatus and a gas detection method which are capable of quickly discriminating natural gas from underground methane.SOLUTION: A search mode for detecting combustible gas in sampled gas, a methane detection mode for, when detecting the combustible gas in the search mode, supplying a predetermined quantity of the sampled gas to a column together with carrier gas and detecting methane from gas passed through the column, and a non-methane detection mode for, after detecting the methane in the methane detection mode, supplying the carrier gas to the column from an opposite direction and detecting gas returned from the column are executed. When detecting the methane in the methane detection mode and detecting the combustible gas other than the methane in the non-methane detection mode, leakage of natural gas is determined. It is possible to quickly discriminate natural gas from underground methane.

摘要： PROBLEM TO BE SOLVED: To be able to release a proper amount of aroma disregarding the size of a room, intensity of ventilation, or the like.SOLUTION: Using a signal of an aroma sensor, an aroma feeder is controlled by a controller. When an attenuation factor is large in the signal of the aroma sensor after the aroma release, an amount of aroma for one release is increased or an interval of aroma release is shortened. When the attenuation factor is small, the amount of aroma for one release is reduced or the interval of aroma release is increased.
