Patents by Inventor Yoko OHKUBO

Yoko OHKUBO 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).

  • Electronic control device
    Patent number: 11330704
    Abstract: An electronic control device includes a housing that stores a substrate on which an electronic component is mounted, a first capacitance unit formed between the housing and the electronic component, and a second capacitance unit formed between the housing and the substrate, in which a noise transmission path is formed between the housing and the substrate via the first capacitance unit and the second capacitance unit.
    Type: Grant
    Filed: November 13, 2018
    Date of Patent: May 10, 2022
    Assignee: HITACHI ASTEMO, LTD.
    Inventors: Masahiro Toyama, Umberto Paoletti, Takeshi Yamakawa, Yoko Ohkubo, Hideyuki Sakamoto

  • Electronic control device
    Patent number: 11122717
    Abstract: To obtain, in an on-board control device, a shield effect against noise radiated from an electronic component. The present invention includes: an electronic component 103; a metal housing 101 which covers at least a part of the electronic component 103; a metal portion 105 which is provided so that the electronic component 103 is disposed between the metal portion 105 and the metal housing 101; and a shield structure which shields radiation noise from the electronic component 103 by electrostatic capacitive coupling formed between the metal portion 105 and the metal housing 101.
