Abstract: A high-temperature resistance is disposed in an internal passage and has its energization controlled based on an intake-air flow rate in the passage to increase/decrease a heat generation amount. A first low-temperature resistance constitutes a bridge circuit which has its energization state changed according to the heat generation amount of the high-temperature resistance. The first low-temperature resistance varies its resistance value according to intake-air temperature. A second low-temperature resistance is an element, which is not incorporated into the bridge circuit and varies its resistance value according to intake-air temperature to increase/decrease an energization amount. The second low-temperature resistance is provided on a substrate. Another bridge circuit produces an intake air amount detection signal using an electrical signal generated by operation of the high-temperature resistance and the first low-temperature resistance. A digital circuit uses an electrical signal produced by the second low-temperature resistance as an intake temperature detection signal.

Abstract: A first passage has a branch position where a second passage is branched from the first passage to move air along a reference vector. The second passage accommodates a thermal sensor. The first passage has a throttle at a downstream of the branch position. The throttle has a throttle wall surface having a normal vector directed inwardly. A width direction is perpendicular to both a flow direction of air in the throttle and the reference vector. The throttle wall surface has a specific region, in which the normal vector includes a vector component in the width direction, and an angle θ between the normal vector and the reference vector is in a range of 90 degrees

Abstract: A communication system includes a flow measuring device and a control device. The flow measuring device includes a flow sensor that generates a flow rate signal which is a signal in accordance with a flow rate of intake air drawn into an internal-combustion engine. The flow measuring device transmits the flow rate signal. The control device receives the flow rate signal and performs at least one of injection control of fuel to be supplied to the engine and ignition control at each cylinder of the engine based on the received flow rate signal. The flow measuring device includes a measurement-side transmitting part that transmits various signals by wireless communication, and transmits the flow rate signal by the measurement-side transmitting part. The control device includes a control-side receiving part that receives the various signals by the wireless communication, and receives the flow rate signal by the control-side receiving part.
