  • Patent number: 11419209
    Abstract: A resin member is formed from a resin material containing filler and an insulating base polymer as a main component. The resin member includes an alignment layer close to a surface of the resin member. The alignment layer includes the filler aligned in the surface direction and the base polymer filling the space between pieces of the filler. The alignment layer includes a carbonized portion that is carbonized matter of the base polymer, contains graphite, and provides electrical conductivity and thermal conductivity.
    Type: Grant
    Filed: January 20, 2021
    Date of Patent: August 16, 2022
    Assignee: DENSO CORPORATION

  • Publication number: 20210164820
    Abstract: A flowmeter is configured to measure a flow rate of a gas flowing through a main passage. The flowmeter includes a housing and a flow rate detector. The housing is made of a resin and includes a bypass passage branched off from the main passage. The flow rate detector is disposed in the bypass passage and transmits detection signals in accordance with the flow rate of the gas flowing through the main passage. The housing includes a non-insulation portion including graphite.

  • Patent number: 10522957
    Abstract: In a power converter, a semiconductor module incorporates therein a semiconductor element that constitutes a power converter circuit. The semiconductor module has a power terminal extending therefrom, and the power terminal has opposing first and second terminal surfaces. The power converter includes a capacitor electrically connected to the semiconductor module. The power converter includes a busbar. The busbar includes a capacitor-connection terminal connected to the capacitor, and at least first and second semiconductor-connection terminals that are at least partly joined to the respective first and second terminal surfaces of the power terminal.
