  • Electronic device
    Patent number: 11765844
    Abstract: A power conversion device, as an electronic device, includes a circuit substrate, a metal housing, an external connection terminal, and an insulator. The external connection terminal projects from the interior to the exterior of the metal housing, and is used to connect an output terminal of the circuit substrate to the exterior. A part of the insulator is disposed between the metal housing and the external connection terminal, and insulates the metal housing and the external connection terminal from one another. A housing extension portion is formed in the metal housing, extending from a body portion of the metal housing, in the inward direction with respect to the metal housing, in a condition facing the external connection terminal. A part of the insulator is disposed between the external connection terminal and the housing extension portion.

  • DRIP CYLINDER NOZZLE AND DRIP CYLINDER
    Publication number: 20190275233
    Abstract: A dripping cylinder includes a housing, a nozzle that has an inflow hole which allows a liquid to flow into the housing and that causes the liquid to drip from an end portion of the inflow hole, and a needle-shaped portion that is held in a state in which at least an end portion of the needle-shaped portion is positioned further downstream than the end portion of the inflow hole of the nozzle in a drip direction.
