    摘要： A thermal type air flowmeter arranges a temperature-dependent heating resistance element in an air flow path and measures the air flow rate from the output of a gauge circuit containing the heating resistance element. A calculation circuit in the flowmeter is provided for correcting the output characteristic by a polynomial expression higher than a quadratic expression. Thereby, high flowmeter measuring accuracy is achieved in lieu of laser trimming and with small-scale circuit composition.

    摘要： In a thermal-type airflow meter that measures an intake airflow rate in an internal combustion engine of an automobile or the like, there has been a problem that pulsation errors caused by external fluctuations under the environment including a large pulsation and reverse flow in the intake valve are difficult to be reduced. In order to solve this problem, the invention provides a flowmeter comprising a detection element that outputs a non-linear signal corresponding to a flow rate, and a regulation means that regulates an output signal of the detection element for controlling. With this construction, the regulation means executes output regulation processing that regulates irregularities of the detection element in the output signal, and inequality linearization processing that regulates an average value of the output signal after the output regulation processing by means of regulating parameters.

    摘要： The present invention improves reliability of an in-vehicle electronic device against corrosive gases. A trapping agent that has trap performances (adsorptive performance, suction performance, absorption performance, chemical reactivity, etc.) that are higher than that of water vapor with respect to corrosive gases other than water vapor is held within a connector having a terminal that is insert-molded in a case housing an electronic circuit. Here, the trapping agent may be held in a counterpart connector of the connector integrally formed in the case.

    摘要： In a flow sensor, detecting elements are provided at a sub-passage. A sub-passage wall contains a hole to drain accumulated liquid. A protrusion arranged close to the hole on an external surface generates dynamic pressure on the opening in response to external flow. Alternatively, a protrusion upstream from the hole on the inner wall surface produces a separation flow area for separating the flow from the internal surface near the hole, whereby pressure in the separation area is reduced and almost the same pressure differences on the internal and external surfaces openings result. This reduces leakage from the hole and changes in the distribution flow in the sub-passage between cases where the hole is blocked and not blocked, thus minimizing flow measurement errors. Structure may be provided close to the external surface hole opening to prevent a liquid film or drop from being formed on the opening by surface tension.

    摘要： A thermal air flow rate measuring apparatus of great precision wherein sensitivity is enhanced by sensors having different output characteristics and an operating device employing a digitized signal. The sensitivity and temperature can be corrected easily depending on the flow direction of fluid. The measuring apparatus includes at least one heating resistor disposed in a gas fluid, temperature detecting resistors formed at an upstream part and a downstream part of the heating resistor in the flow direction of the fluid, a device for outputting at least two signals relating to the flow rate of the fluid, a quantizing device for quantizing the output values, and an operating device for operating the flow rate based on the quantized signals.
