  • Patent number: 9506738
    Abstract: A rod-shaped magnet is mounted on a rotating unit. The rod-shaped magnet has end surfaces which are oriented in a rotating direction and are magnetized to different magnetic poles. An angle detecting unit including magnetoresistive elements is disposed so as to be offset in a radial direction of a revolution path of the magnet from the revolution path and is configured to detect a change in angle of rotation of the rotating unit by detecting a leakage magnetic field in the vicinity of a side surface of the magnet. Two position detecting units each include magnetoresistive elements and are configured to detect a change in orientation of a magnetic field in the direction of a tangent to the revolution path when facing the rod-shaped magnet and produce a switch output.

  • Publication number: 20120217961
    Abstract: A magnetic sensor includes a plurality of magnetoresistance effect elements and soft magnetic bodies. Each of the magnetoresistance effect elements is formed by stacking a magnetic layer and a non-magnetic layer on a substrate so as to exhibit a magnetoresistance effect. The magnetoresistance effect element is configured such that element portions and electrode layers are alternately disposed. A soft magnetic body is disposed on one and the other sides of each of the element portions in the Y direction, and the soft magnetic bodies are displaced from each other in the X direction. With this arrangement, an external magnetic field applied in the X1 direction is changed into an external magnetic field in the Y direction when passing through the soft magnetic bodies, and the changed external magnetic field flows into the element portions.

  • Patent number: 8102172
    Abstract: A circular top surface of a magnet is magnetized to the N-pole, and a back surface thereof is magnetized to the S-pole. A detector moves within the X-Y plane at positions located away from the top surface of the magnet. A pair of X-direction detecting elements and a pair of the Y-direction detecting elements are provided in the detector. In the X-direction detecting elements, the directions of a bias magnetic field provided to free magnetic layers are opposite to each other. When the detector moves in the Y direction, a decrease in the sensitivity of one of the X-direction detecting elements is compensated for by an improvement in the sensitivity of the other element. This also applies to the Y-direction detecting elements. Accordingly, position detection outputs of the X direction and the Y direction can be accurately obtained from the detector.
