  • ELECTROMAGNETIC VALVE UNIT
    Publication number: 20230323977
    Abstract: An electromagnetic valve unit held so as to be sandwiched between a receiving portion of a housing portion of control equipment and a pressing member includes a shoulder portion to be opposed to the receiving portion of the housing portion and an annular elastic member provided with a protruded portion to be inserted into a recessed portion formed at the shoulder portion. The annular elastic member is further provided with an annular deformation portion that is deformable in the axial direction so as not to press the protruded portion in the axial direction.
    Type: Application

  • Solid electrolytic capacitor and method for manufacturing the same
    Patent number: 9263193
    Abstract: A solid electrolytic capacitor includes: a porous sintered body; an anode wire extending in a first direction and connected to the porous sintered body such that one end portion of the anode wire in the first direction is exposed; a resin package covering the porous sintered body and the anode wire; and a lead including a terminal exposed from the resin package and a lead side connector connected to the terminal. The anode wire includes a base and a connector placed at one side of the base in the first direction, a sectional area of the connector is smaller than that of the base, and the connector and the lead side connector are welded together.
