摘要： The invention is intended to improve reliability of a thermal type air flow measuring instrument employing a molded part formed by integral molding together with a metal plate. A slot or opening allowing only a resin to pass through the same is formed in the metal plate in an area or thereabout subjected to higher stresses. A part of connector terminals, which is not required from the intrinsic object, is disposed in the vicinity of a area where the resin has a larger thickness and the temperature difference between the inside and the outside of the resin is locally increased. An injecting direction is set so as to prevent a weld line and a void from being generated in a combined way. In the molded part with the metal plate inserted therein, the occurrence of cracks and an increase of the fatigue crack growth rate can be suppressed and reliability can be improved.

摘要： A heating resistor flow rate measuring instrument, having a heating resistor and a thermally sensitive resistor disposed in a sub-passage of a main passage. The heating resistor is disposed in a portion of the sub-passage which has an upstream-side opening substantially perpendicular to the forward direction of a fluid flow and a downstream-side opening substantially parallel to the reverse flaw direction, and the thermally sensitive resistor is disposed in a second sub-passage portion having an upstream-side opening substantially parallel to the forward flow direction and a downstream-side opening substantially perpendicular to the reverse flow direction. Based on changes in resistor temperatures when the flow direction reverses, a precise flow rate may be determined even when a pulsation occurs in the fluid, as both a plus effect caused by a backward flow is eliminated and a value corresponding to the backward flow may be subtracted to obtain accurate flow information.
