摘要： A flow measuring device has a sensor element for outputting a nonlinear signal according to a flow rate. In the device, a first signal processing system obtains a first signal by filtering the nonlinear signal output from the sensor element, thereafter corrects a sensitivity of the filtered signal. A second signal processing system obtains a second signal by linearizing the nonlinear signal from the sensor element, thereafter filters the linearized signal and corrects a sensitivity of the filtered signal, and then non-linearizes the linearized signal with a corrected sensitivity. An amplifier amplifies a differential signal between the first and second signals. A correcting section corrects the nonlinear signal by using the amplified differential signal.

摘要： To offer a mass airflow measuring apparatus in which the effect of the adhesion onto the heating resistor 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： A hot-wire type air flow meter for an internal combustion engine has an exothermic resistor film provided on a thin portion formed on a silicon substrate and a control circuit for controlling a voltage to be applied to the resistor film or a current to be supplied. The resistor film is arranged in a suction pipe of the internal combustion engine and heat is emitted to an air through the resistor film. In the case where a liquid droplet is deposited onto the resistor film, the control circuit controls the applied voltage to a value smaller than a voltage which is applied to the resistor film at the time of measuring a maximum specified measuring range or controls the supply current to a value smaller than a current flowing in the resistor film at the time of measuring the maximum specified measuring range.

摘要： Thermal type flow rate meters for measuring the flow rate of intake air of an internal combustion engine of a motor vehicle or the like have encountered a problem of an increase in pulsation errors during high engine speed and high pulsation. Meanwhile, digitally recovering responses has posed a problem in which pulsation performance is liable to become worse, affected by variation in a clock or the like. The sensor is provided with means for transferring a response variation factor to the engine control unit. The engine control unit is provided with logics for automatically determining the variation factor and correcting a response. Means for detecting a backflow occurrence is provided and a parameter for a response recovery is changed before and after a backflow occurrence. The sensor is provided with a selecting means by which a sensor response can be selected and obtained and the engine control unit is provided means for allowing selection of a response.

摘要： The liquid crystal cell (30) for the optical change-over switch comprises a pair of transparent substrates (1), a pair of transparent flat electrodes (2) provided on the respective opposing surfaces of the substrates, orientation control films (3) provided on the flat electrodes (2), two pair of comb shaped electrodes (33) respectively provided on the orientation control films (3), and a ferroelectric liquid crystal layer (4) confined between the substrates (1). The optical incidence plane (31) to the cell (30) is so selected that the plane (31) is away from the helical axes (9) of the ferroelectric liquid crystal in the cell (30) in the order of somewhat greater than the tilt angle (.theta..sub.t) of the ferroelectric liquid crystal. The pair of flat electrodes (2) generate a first electric field (37a) perpendicular to the layer (32) and orient the long axes of the ferroelectric liquid crystal molecules into a first orientation (35a') parallel to the layer (32 ) to induce a first refractive index which causes simultaneous reflection of unpolarized light beam (7+8) with a predetermined incidence angle (.theta.). The two pair of comb shaped electrodes (33) generate a second electric field (37b') parallel to the layer and perpendicular to the helical axes (9) and orient the long axes of the molecules into a second orientation (35b') not in parallel to the layer (32) to induce a second refractive index which causes simultaneous transmission of the unpolarized light beam (7+8) with the predetermined incidence angle (.theta.).
