  • Patent number: 10654104
    Abstract: A sintered bearing comprises: a bearing sleeve that is formed of a sintered material and has a shaft hole; an annular ring-shaped seal member that is disposed such that one surface thereof comes into contact with the bearing sleeve; and a washer member that comes into contact with the other surface of the seal member on a side opposite to the one surface and is configured for the seal member to engage with the bearing sleeve. The washer member is fixed to the bearing sleeve.
    Type: Grant
    Filed: November 16, 2017
    Date of Patent: May 19, 2020
    Assignees: Diamet Corporation, MITSUBISHI CABLE INDUSTRIES, LTD.

  • Patent number: 5803938
    Abstract: A liquid vaporizing apparatus includes a container for holding a liquid at a constant temperature with a temperature adjustment unit and a gas that does not react with the liquid is bubbled through the liquid in the container to vaporize the liquid. The container for holding the liquid has an internal space above the liquid and a second temperature adjustment unit for controlling the temperature of the internal space separately from the temperature of the liquid in the container. Since the internal space is maintained at a constant temperature, higher than the temperature of the liquid, the quantity of the vaporized liquid produced is stable.
    Type: Grant
