  • On-vehicle electronic device and motor-driven compressor
    Patent number: 10024312
    Abstract: An inverter includes a bus bar as a wiring and a ferrite core that covers the bus bar to absorb electromagnetic noise from the bus bar. The bus bar and ferrite core are integrated by mold forming using a resin material in a state of exposing a part of the ferrite core.
    Type: Grant
    Filed: November 12, 2015
    Date of Patent: July 17, 2018
    Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKI
    Inventors: Satoshi Okada, Shinya Sato, Takao Kawasaki, Tetsuya Yamada, Kenji Maemura
  • Scroll-type compressor with gas passage formed in orbiting plate to restrict flow from compression chamber to back pressure chamber
    Patent number: 9624928
    Abstract: The orbiting base plate has a compression side surface and a back pressure chamber side surface. The gas passage has an opening in the compression side surface of the orbiting base plate between portions of the orbiting spiral wall that face each other, and the gas passage has an opening in the back pressure side surface at a position that faces an area on a radially inner side than the outer circumference of the bearing, so as to feed the refrigerant gas in the compression chamber to the back pressure chamber.

  • SCROLL-TYPE COMPRESSOR
    Publication number: 20150104342
    Abstract: The orbiting base plate 61 has a compression side surface and a back pressure chamber side surface. The gas passage 64 has an opening 641 in the compression side surface of the orbiting base plate 61 between portions of the orbiting spiral wall 62 that face each other, and the gas passage 64 has an opening 642 in the back pressure side surface at a position that faces an area on a radially inner side than the outer circumference of the bearing 5, so as to feed the refrigerant gas in the compression chamber 15 to the back pressure chamber 16.
