An arrangement for measuring a quantity of intake air passing through an intake air duct by a sensing element disposed in parallel with a flow direction of the intake air. The sensing element includes a flow speed sensing resistor deposited on a base plate and formed into a film for sensing a flow speed of the intake air, and a pair of lead members deposited on the base plate and electrically connected to the resistor. The flow speed sensing resistor is arranged to form a temperature distribution of the resistor uniform in a direction parallel with and/or perpendicular to the flow direction of the intake air.

Intake air quantity measuring apparatus

The invention is directed to an arrangement for measuring a quantity of intake air passing through an intake air duct by a sensing element disposed in parallel with a flow direction of the intake air. The sensing element includes a flow speed sensing resistor deposited on a base plate and formed into a film for sensing a flow speed of the intake air, and a pair of lead members deposited on the base plate and electrically connected to the resistor. The flow speed sensing resistor is arranged to form a temperature distribution of the resistor uniform in a direction parallel with and/or perpendicular to the flow direction of the intake air.

The invention is directed to an arrangement for detecting a rotational angle of a rotating shaft by a sensor. The sensor includes a substrate and a detecting element which has a plurality of blocks of magnetoresistance element deposited on a planar surface of the substrate. The sensor also includes a magneto member which has a pair of magnetic poles facing each side end of the substrate respectively and providing a magnetic field covering at least the planar surface of the substrate. The sensor is so arranged that one of the detecting element and the magneto member is mounted on the rotating shaft, and the other is disposed at a certain position relative to the rotating shaft. Accordingly, the blocks of magnetoresistance element are disposed always in a uniform magnetic field, so that the rotational angle is detected accurately.
