Munehisa Nakamura has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Magnetic sensor, magnetic sensor device, and torque sensor
    Patent number: 6513396
    Abstract: A cylindrical rotating member is provided with a magnetic element, which are an object that is detected, on the outer surface thereof. The magnetic element is led around the rotating member by one turn and is at an angle relative to the rotating direction of the rotating member in an approximately linear manner. End portions of the magnetic element are disposed at approximately the same position in the radial direction of the rotating member. Magnetoresistive elements are arranged in a direction perpendicular to the rotating direction of the magnetic element (in other words, axial direction of the rotating member) with a gap therebetween and oppose the magnetic element.
    Type: Grant
