摘要： A rotation-angle-detection device includes a main housing, a resinous cover for covering an opening of the main housing, a permanent magnet disposed at the main housing to be rotatable in response to rotation of a throttle valve, and a magnetic sensor. The cover is longer in longitudinal direction than in lateral direction, and the magnetic sensor is fixed to the resinous cover. The magnetic sensor is disposed so that the detection direction and the longitudinal direction of the cover cross each other at a right angle.

摘要： Non-contact type Hall ICs detecting an rotation angle of a throttle valve, a stator core strengthening a magnetic field around the Hall ICs, a lead frame connecting the Hall ICs to an outside ECU are integrated in a sensor cover by resin molding. Thus, the Hall ICs, the stator core, and the lead frame are accurately positioned in the sensor cover. As a result, the Hall ICs are accurately positioned with respect to a permanent magnet disposed in a shaft side of the throttle valve, thereby improving an accuracy of detecting the rotation angle of the throttle valve.

摘要： A stator core has a detecting portion located on a center of a gap penetrating the stator core in a diametric direction and a Hall IC arranged in the detecting portion. Large gap portions each having a distance G3 wider than a distance G2 of the detecting portion are formed on both sides of the detecting portion. Therefore, a magnetic flux passing through the stator core is concentrated into the detecting portion, and the magnetic flux density passing through the Hall IC is increased. As a result, an output of the Hall IC is increased. The large gap portion is formed to narrower a distance G4 on an outer side of the stator core, and the distance G4 is wider than an air gap G1 between the permanent magnet and the stator core.

摘要： A compact and high-accuracy angular position measuring device is provided which has magnets installed in a rotor core and a magnetic sensor installed in a stator core. The magnetic sensor produces an output indicative of an angular position of the rotor core as a function of a change in density of magnetic flux produced by the magnets. The magnets are so arranged in the rotor core that the same poles are opposed magnetically to produce a repellent force in magnetic fields of the magnets, thereby causing the magnetic flux to go to the magnetic sensor through the rotor core. This eliminates the need for an air gap between the stator core and the poles of the magnets which is formed in a conventional device, thus allowing the device to be reduced in size and an error in output of the device to be decreased.

摘要： In a magnetic rotation angle sensor for detecting a rotation angle of a detection target, a yoke covers outer circumferences of a magnet and a Hall device. One of the magnet and the magnetic flux density detection device rotates together with the detection target. The Hall IC is radially shifted from a rotation center of the detection target. The magnetic flux density detection device has a detection surface that is in parallel to one of a tangential direction and a normal direction of a turning circle. The magnet is magnetized in the one of the tangential direction and the normal direction of the turning circle.

摘要： A terminal-supporting apparatus includes a resin part made of non-conductive resin material and a plurality of conductive terminals including parallel terminal portions which are directly supported by the resin part. The parallel terminal portions are electrically connected to each other through an electric element. The resin part supporting the parallel terminal portions is made of non-conductive resin material mixed with non-conductive reinforced fibers of which thermal expansion coefficient is smaller than that of the non-conductive resin material. An extending direction of the parallel terminal portion is referred to as a longitudinal direction and a direction perpendicular to the longitudinal direction is referred to as a perpendicular direction. The non-conductive reinforced fibers have a fiber direction which is substantially the same as the perpendicular direction.
