摘要： An air temperature sensor sensing an air temperature, supplied with a pulse signal as a driving signal from a pulse signal source, senses an air temperature based on the pulse signal. While the air temperature sensor is self-heated during an electrical current supplying time period by the pulse signal, it is cooled during an electrical current halting time period. Accordingly, the self-heating of the air temperature sensor by the driving signal is suppressed, and a thermal effect on air flow rate sensing elements disposed in an air flow downstream side of the air temperature sensor is also reduced.

摘要： A heating resistance flow rate measuring apparatus which can use a power source of an ECU in an automobile without requiring an expensive protective circuit and regulator. Heating of temperature detecting resistors themselves causes temperature changes on the windward and leeward sides, and these temperature changes depend on the amounts of heat generated by the temperature detecting resistors. The amounts of heat generated by the temperature detecting resistors depend on a voltage value of the ECU power source applied to the temperature detecting resistors, and an error is caused in a sensor output depending on a variation in the voltage of the ECU power source. Based on the finding that suppressing the amount of heat generated by the temperature detecting resistors is effective in avoiding the sensor output error caused depending on a variation in the output voltage of the ECU power source, means for suppressing the amount of heat generated by the temperature detecting resistors is disposed.
