Title: Method and apparatus for detection of gas
Inventor: MATSUURA YOSHINOBU
IPC: G01N27/04
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To prevent a change with the passage of time of a pulse-driven gas sensor by a method wherein a sensor-side switch by which a metal oxide semiconductor film and a load resistance are connected to a power supply is installed and the sensor- side switch is turned on in synchronization with the turning-on operation of a heater- side switch. SOLUTION: The degradation with the passage of time of a gas sensor is caused when Mg ions or the like are added to a metal oxide semiconductor film from an insulating film or the like. While the sensor is cooled down to room temperature, the Mg ions are eluted to adsorption water from an insulating glass, they are segregated to the side of a cathode by a detection voltage, and a sensor characteristic is degraded. Then, the detection voltage is synchronized with a heater voltage, and the degradation of the sensor is prevented by a method in which the duty ratio of an increase in the detection voltage is reduced. An insulating substrate 2, a heat- insulating glass film 4, a heater film 6 and heater films 8, 10 which are composed of an Au film are provided. An insulating film 12 is composed of a glass which contains Mg.  A material whose thermal conductivity is small is used for the substrate 2, the heater film 6 surrounds the circumference of a semiconductor film 16 so as to be heated, and the contamination of the semiconductor film 16 from the substrate 2 is prevented in a sensor 30.
