Title: Production of gaseous ethanol sensor
Inventor: FUJIOKA TORU
IPC: G01N27/12
Filed: 1986-03-15
Abstract: PURPOSE:To obtain a sensor which has high sensitivity and selectivity to a gaseous ethanol, has excellent stability and reliability and is inexpensive and easily maintainable by using a semiconductor photocatalyst material which generates a catalytic effect when irradiated with light as a gas sensing part. CONSTITUTION:A TiO2 layer 3 consisting of the semiconductor photocatalyst material which has the catalytic effect when irradiated with light is formed on a quartz glass substrate 2. The surface of the TiO2 3 layer to be irradiated with the light is provided with a pair of electrodes 4a, 4b made into a comb shape. The TiO2 layer 3 is formed by using, for example, TiO2 having high purity as a target material and forming the layer by an electron beam vapor deposition method. The layer is subjected to a prescribed heat treatment in an oxidative atmosphere after the vapor deposition, by which the oxygen defects contained in the formed TiO2 layer are decreased and the impurity level in the TiO2 layer is made lower. The function as the photocatalyst material is thus additionally improved. The electrical change of the TiO2 generated by the gaseous ethanol while the sensor is irradiated with the light and has the catalytic effect is taken out a detection signal of the gaseous ethanol from the electrodes 4a, 4b with high sensitivity.

Abstract: PURPOSE:To set an optical voltage amplification factor and to limit optionally its output current at the same time by connecting a base of a 2nd transistor(TR) to the base of a 1st TR so as to regulate the operation of the 1st TR by the 2nd TR when an output current of a differential amplifier circuit reaches a prescribed value or over. CONSTITUTION:The circuit is constituted by connecting a base of a TR Q6 to a base of a TR Q5, connecting a collector of the TR Q6 to a current source 3 and also to a base of a TR Q7, and connecting an emitter of the TR Q7 to a base of the TR Q5. Through the constitution above, the voltage amplification factor of an open loop is set higher by the TR Q5. Moreover, the sink current is limited by a current of a current source 2 and the source current is limited by a current of the current source 3. That is, with a current over a current 2I2 flowing to the collector of the TR Q6, the base potential of the TR Q5 rises to limit the output current. Thus, both the source and sink output currents are limited in this circuit by using the current I2.
