Filed: 2003-03-03
Abstract: <P>PROBLEM TO BE SOLVED: To promote self-heating of thermistors and reduce a start-up time, without a separate power supply in a thermal conduction gas sensor which uses the thermistors.  <P>SOLUTION: A current-limiting resistor R1, a first three-way switch 3 and a second three-way switch 4 are connected in series between a power supply 5 and a bridge circuit.
