| titleOfInvention | Temperature control device for oxygen concentration sensor |
| abstract | PURPOSE: To prevent migration, to avoid wire breakdown and to prevent deterioration, by alternately imparting voltages, whose polarities are different, to a heating element, which heats an oxygen-concentration detecting element. n CONSTITUTION: A pump element faces an oxygen-concentration-ratio measuring element 2, with a slit 3 having a width in between. A heating element 22 is attached to the outer surface of the pump element 1. The heating element 22 comprises a rectangular, insulating inorganic plate body. A rectangular hole 11 is provided in a part corresponding to the electrode of the pump element 1. A Pt wire 24 is printed around the hole 11. A heater-current supplying circuit 23 is connected to the electrode at the end part of the wire 24. Transistors 25W28 are alternately conducted by the operation of an amplifier 29 and an inverted amplifier 30. Therefore AC flows through the Pt wire 24. Since electrons flows in the Pt wire 24 with their direction being alternately changed, the temperature of the heating element 22 can be increased without moving the ionized Pt in one direction. n COPYRIGHT: (C)1987,JPO&Japio |
