  • Method and apparatus for forming a casting which includes an insert
    Patent number: 6923632
    Abstract: An insert is held in a cavity within a die set by a movable hold member. Molten resin is injected into the cavity when the insert is held by the hold member. The hold member is separated from the insert at a given timing. A surface of the hold member is heated to a temperature higher than a temperature of an inner surface of the die set. The hold-member surface contacts the molten resin. The die-set inner surface is exposed in the cavity.
    Type: Grant
    Filed: September 19, 2001
    Date of Patent: August 2, 2005
    Assignee: Denso Corporation
    Inventors: Hiroshi Koyama, Tsutomu Onoue, Keigo Asano, Tadatsugu Nakamura, Izuru Shoji

  • Magnetoresistive type position sensor having bias magnetic and magnet resistance elements in bias magnetic field thereof
    Patent number: 6020736
    Abstract: A rotation object is made of a magnetic material and disposed within a predetermined range of an angle of rotation on a plane perpendicular to an axis of rotation. A bias magnet generates a bias magnetic field to the rotation body in a direction perpendicular to the axis of rotation. Magnetic resistance elements are disposed in the bias magnetic field on a plane including the axis of rotation at a position deviated from the position of the rotation object in the axial direction of the rotation body and inclined by about 45.degree. relative to a direction perpendicular to the axis of rotation.
