  • Patent number: 10374490
    Abstract: An electronic device includes a heat sink, where heat dissipating gel is interposed between the heat sink and a side of an electronic component, which is mounted on a substrate, opposite from the substrate. The electronic component includes an electrical conductor electrically connected to a chip, and an insulator portion that molds the chip with the electrical conductor. The heat sink includes a non-abutting surface that faces the electrical conductor of the electronic component, the heat dissipating gel interposed between the non-abutting surface and the electrical conductor, and an abutting surface that is positioned closer toward the substrate than the non-abutting surface is and abuttable with the insulator portion. Accordingly, when the abutting surface of the heat sink abuts the insulator portion of the electronic component, the non-abutting surface of the heat sink is prevented from abutting the electrical conductor of the electronic component.

  • Patent number: 9791298
    Abstract: A rotation angle detector has a rotation angle sensor and a microcomputer, where the sensor detects a change of a magnetic field of a magnet that rotates with a shaft. The microcomputer has a first corrector for correcting a pre-correction mechanical angle, based on a first correction value that corrects an error due to an assembly process for assembling the magnet and the sensor, and a second corrector for correcting the pre-correction mechanical angle based on a second correction value that corrects an error due to a spill magnetic flux that is generated by a supply of an electric current to a winding wire. In such configuration, the rotation angle detector may correct the error due to the spill magnetic flux, thereby enabling an accurate detection of a mechanical angle.

  • Patent number: 9473004
    Abstract: A drive device that includes a motor having a rotor disposed relative to a stator, a cover having a one-end-closed cylinder shape and positioned on one axial end side of the motor, and a substrate on the inside of the cover perpendicular to a motor shaft having electronic components implemented on the substrate. The drive device also includes a connector positioned on a motor side of the substrate with an opening that is connectable to an external terminal. The opening of the connector faces outward relative to the motor shaft. The drive device further includes a heat sink having a frame end part and a heat receiving part formed in one body. The drive device increases heat capacity of the heat sink without increasing its height.
