  • Displacement detector with relatively movable magnet and sensor
    Patent number: 6552532
    Abstract: A magnetic sensor having a simple structure and high accuracy for detecting a linear or angular displacement thereof. A magnetic plate with tapered thickness is magnetized in a direction perpendicular to its surface. A magnetic sensor is arranged so that it can move in the direction of the taper of the plate thickness. A drive mechanism for this magnetic sensor is movable with an object to be detected, and the output of the magnetic sensor indicates the displacement.

  • Lever type operating device
    Publication number: 20020149565
    Abstract: A joystick is simplified in construction to improve durability. A lever is fixed to spherical or cylindrical magnet, which is also used as a lever fulcrum by being turnably supported, and a magnetic sensor is disposed close to the surface of the magnet, wherein the inclination of the lever is detected by a change in the intensity of the magnetic field on the magnet surface due to spacing from the magnetic pole, the detection output being used as an operating signal.
