摘要： The present invention relates to a thermal type gas flow measuring instrument that measures gas flow with high precision by accurately correcting changes in radiation heat characteristics of a heating resistor (3) due to contamination. The instrument comprises a second heating resistor (30) whose resistance value, which changes if contaminated, is calculated by measuring the terminal voltage thereof by calculating means (32), and the calculated value is compared with a temperature detected by a temperature detecting element (31). Based on the result of comparison, the level of contamination of the second heating resistor (30) is determined. The second heating resistor (30) and the first heating resistor (3) are disposed in similar environments such that their levels of contamination can be considered equal. Based on the level of contamination calculated from the result of comparison, a correction value is calculated and the output of the first heating resistor (3) is corrected in accordance with the correction value.

摘要： The invention relates to a mass airflow measuring apparatus (3) in which the effect of the adhesion onto the heating resistor (1) caused while the engine is off is reduced and the measuring accuracy is improved. The apparatus measures the mass airflow of the air sucked into the internal combustion engine, using the heating resistor (1). The power control circuit (4) maintains the heating resistor (1) temperature equal to or higher than the temperature during the operation of the internal combustion engine after the internal combustion engine has stopped and until the temperature of the internal combustion engine and its apparatuses installed in the suction system has lowered below the generation temperature of volatile gas such as oil vapor. The power control circuit (4) using the temperature sensing resistor (2) that detects the temperature of the air sucked into the combustion engine, detects the air temperature and maintains the heating resistor (1) temperature, based on the temperature measured, equal to or higher than the temperature during the operation of the internal combustion engine even after the internal combustion engine has stopped.

摘要： Disposed in a intake pipe (13) of an engine is a temperature-sensitive element (17) formed of a resistance element whose resistance value varies with temperature. A heating current is supplied to the temperature-sensitive element (17) through a transistor (37). The voltage of the heating current is set by a constant-voltage circuit (38, 49). The temperature of the temperature-sensitive element (17) is compared with a reference temperature of an auxiliary temperature-sensitive element (30). When the temperature of the temperature-sensitive element (17) is increased to a predetermined level, an output signal is delivered from a comparator (33). A flip-flop circuit (34) is reset by the output signal from the comparator (33), and is set by a start pulse signal. When the flip-flop circuit (34) is set, the transistor (37) is turned on, allowing the heating current to be supplied to the temperature-sensitive element (17). A burning-off instruction signal is supplied to a monostable multivibrator (42), and a signal with a) duration suited for the burning-off operation is delivered' from an AND circuit (43). In response to the output signal from the AND circuit (43), the flip-flop circuit (34) is held set, and a reference voltage supplied to the differential amplifier (39) is changed to a low level.
