摘要： In a thermal type flow rate measurement apparatus comprising a sub-passage having a detour passage and a hole just before a flow rate measuring part, for preventing its output value from falling onto a negative side when the flow rate is abruptly changed, a slit is formed downstream of a flow rate detecting element located after the detour passage. The slit hole may be arranged between the flow rate detecting element and the outlet port part, and may be opened between a wall surface side and a recess part. Thereby, it is possible to prevent the output value from falling in the negative side upon rise-up thereof.

摘要： A thermal type air flow measuring instrument has a molded part formed by integral molding 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 subjected to higher stresses. A part of the connector terminals are disposed in the vicinity of an area where the resin has a larger thickness and the temperature difference between the inside and the outside of the resin is locally increased. The injecting direction is set to prevent a weld line and a void from being generated. For the molded part with the metal plate inserted therein, the occurrence of cracks is minimized. Further, an increase of the fatigue crack growth rate is decreased.

摘要： To realize a control apparatus for an internal combustion engine having a heating resistor type air flow rate measuring apparatus which can effectively remove salinity adhered to the heating resistor. Salt adheres not only to the heating portion of a heating resistor but also to lead members and supporting members. When a certain time period is passed after the current supply to the heating resistor is stopped, the salt adhered thereto absorbs moisture in the air by deliquescence, and becomes salt water near the heating resistor and the support members etc. Then, suction air flows through an auxiliary air passage by the cranking of the engine to disperse the salt water adhered not only to the support member parts but also to the heating resistor. Thus, even if the heating resistor is supplied with current after the dissipation, salt components do not remain on the heating resistor.

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.
