  • Patent number: 11870379
    Abstract: The control device includes a target-value calculation unit calculating a target-value of a controlled variable that is torque of a rotating electrical machine, drive force, or acceleration of a vehicle, based on redundant signal and non-redundant signals, an inverter operation unit operating the inverter to control the controlled variable to the target-value, and a monitoring-value calculation unit calculating a target-monitoring-value of the controlled variable based on the redundant signal.
    Type: Grant
    Filed: July 11, 2022
    Date of Patent: January 9, 2024
    Assignee: DENSO CORPORATION
    Inventors: Tarou Hirai, Shigeru Kamio

  • Patent number: 10468801
    Abstract: A terminal that can be simply joined in the atmosphere; an electrical apparatus including the terminal; and a method of attaching a terminal to a housing made of a metal material by which a passivation film is readily formed on a surface thereof are provided. A terminal can be fixedly adhered to a housing, and includes: a metal outer ring; a lead penetrating through the metal outer ring; and an insulating material providing sealing between the metal outer ring and the lead. The metal outer ring has a joint edge to be joined to the housing. A coating layer turning into a liquid phase at a temperature lower than a melting temperature of the housing is provided at least in the joint edge.

  • Patent number: 10249443
    Abstract: According to a hermetic terminal based on the present invention, a hermetic terminal (10) to be hermetically fixed to an aluminum electrolytic capacitor (20) includes: a base (11) which has a through hole, is to be attached to a case (16) of the aluminum electrolytic capacitor (20), and is made of a composite material having electrical conductivity; at least one lead (12) which is inserted into the through hole of the base (11), and is made of a composite material having electrical conductivity; and an insulating glass (13) which hermetically seals a gap between the base (11) and the lead (12). Surfaces of portions of the base (11) and the lead (12) which come into contact with an electrolytic solution within the case (16) are composed of a metal material having corrosion resistance to the electrolytic solution.
