Thus formed sensor is operable at low temperature less than 500 deg.C. When O2 partial pressure is increased, electrical resistance  decreases, and when there exists CO, O2 partial pressure varies as CO burns  with O2 when exists. Taking full advantage of the above phenomena, O2 and  CO can be determined high-sensitively.

Title: Power unit of electrostatic precipitator
Inventor: YOSHIOKA TORU
IPC: B03C3/66
Filed: 1988-07-07
Abstract: PURPOSE:To stabilize the output of the power unit, i.e., oscillation condition, of electrostatic precipitator by connecting a diode between the base of a transistor for oscillation and a feedback winding and constituting the device in such a manner that the base current supplied from a DC power source to this TR does not make side flow to the feedback winding. CONSTITUTION:Since the diode 31 is reverse biased at the time of starting, the side flow of the base current Ib supplied via a resistor 17 and flowing toward the TR 16 for oscillation to the feedback winding 15 side is suppressed. The diode 31 is forward biased when this TR 16 turns on and an induced voltage Vb is generated in the feedback winding 15. The increase of the base current Ib by the induced voltage Vb is, therefore, surely and sufficiently executed. Further, the 2nd diode 32 connected in parallel with the series circuit of the resistor 18 and the diode 31 is forward biased and the TR 16 is switched to an off state when the induced voltage in the reverse direction is generated in the feedback winding 15 after the TR 16 for oscillation attains a satd. state.
