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 displacement measuring device includes a stationary magnetic member for providing an accommodation space and a first and second magnetic circuits, a movable magnetic member disposed in the accommodation space to move in its longitudinal direction, a magnetic sensor for sensing magnetic flux flowing in the first and second magnetic circuits. The stationary member includes a sensor supporting member disposed in line with an axis of symmetry, a pair of yoke members axisymmetrically disposed at opposite sides of the sensor supporting member, a pair of permanent magnets each of which is disposed between one of the yoke members and the sensor supporting member. The permanent magnets are polarized so that magnetic flux flows in one of the magnetic circuits opposite in direction to magnetic flux flowing in the other magnetic circuit. The magnetic sensor is disposed on the sensor supporting member to confront the moving magnetic member at a first air gap. Each of the yoke members has a projection extending in parallel with the longitudinal direction of the movable magnetic member at a second air gap. Therefore, magnetic permeance of the first and second magnetic circuits changes when the moving magnetic member moves in the longitudinal direction thereof.

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： A permanent magnet is fixed to a stationary portion. A yoke made of magnetic material is provided to a rotating portion. The yoke is tube-shaped to surround the permanent magnet and has a chord portion into which a magnetic flux generated by the permanent magnet preferentially flows. The chord portion is arranged in such a manner as to be close to the permanent magnet. A Hall element is arranged at a specified position of the stationary portion relative to the permanent magnet 20. The Hall element outputs a signal which corresponds to a density and an angle of a magnetic flux generated between the chord portion and the permanent magnet.

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 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.
