Abstract: A flammable gas concentration detection apparatus (1) including an energization control unit (50) that switches the energization state of heating resistor (34) at regular time periods TW, and a gas concentration computation unit (7). The heating resistor has first and second set temperatures CH and CL. The voltage detected across the heating resistor at the first and second set temperatures corresponds to a high and low temperature voltage, respectively. The gas concentration computation unit computes the concentration of a flammable gas based on a first information group including an average high temperature voltage averaging the values of two temporally successive high temperature voltages, the low temperature voltage in a period of time between two high temperature voltages, and an environment temperature in the period of time in which the low temperature voltage is detected.

Abstract: A first bridge fixed resistor (211) of a combustible gas detection apparatus (1) is composed of a resistor element which is less likely to deteriorate as compared with a second bridge fixed resistor (212) and a variable resistor section (213). The combustible gas detection apparatus (1) can judge a deteriorated state of at least one of the second bridge fixed resistor (212) and the variable resistor section (213) on the basis of the absolute value of a difference temperature ?T which is the difference between a detection-time judgment temperature T1 and a reference judgment temperature T0. The combustible gas detection apparatus (1) obtains a corrected high-temperature-time voltage VH? and a corrected low-temperature-time voltage VL? through use of a voltage error ?V1. Thus, a decrease in the accuracy in detecting the hydrogen concentration can be suppressed even when the resistance of the resistor section changes.

Abstract: A gas detector includes a gas detection element having a protection layer formed of an oxide film mainly containing tantalum oxide (Ta2O5). Since the protection layer has excellent condensed-water resistance, even when water droplets adhere thereto, the morphology thereof does not change from dense to porous. Thus, since a change in property of the protection layer, which would otherwise be caused by adhesion of water droplets, can be reduced in the gas detector, even when water droplets adhere to the outermost surface layer of the gas detection element, impurities can be prevented from entering the protection layer (the outermost surface layer), whereby a change in thermal capacity of the gas detection element can be reduced. Thus, the gas detection element of the gas detector has excellent alkali resistance and condensed-water resistance.

Abstract: A gas detector for use in, for example, measuring the concentration of flammable gas or detecting leakage of flammable gas. The gas detector has a gas detection element in which at least a heat-generating resistor and an insulation layer are laminated on a semiconductor substrate made of silicon while the insulation layer encloses the heat-generating resistor. The gas detector detects flammable gas on the basis of temperature and resistance of the heat-generating resistor which vary according to flammable gas. In the gas detection element, a protection layer in the form of a gas impermeable oxide film is provided on its outermost surface which comes into contact with an environmental atmosphere that contains flammable gas. Thus, alkali resistance is ensured. Since the protection layer is impermeable to gas, entry of impurities (organic silicon) contained in the environmental atmosphere into the protection layer is restrained, whereby output is stabilized and becomes accurate.
