  • Electric device sealing structure
    Patent number: 6496090
    Abstract: Casing 5 is formed with a recess 67 toward an internal space in which the internal components are not located. The recess 67 is formed with a gate portion 69 as a resin inlet for forming the casing 5, and a bleeder portion 68 which is opened during a sealing operation and then sealed.
    Type: Grant

    Assignee: Omron Corporation
    Inventors: Takeshi Nishida, Takashi Asao, Jiro Kumagae, Masanori Nakamura
  • Electromagnetic relay
    Patent number: 5969586
    Abstract: In an electromagnetic relay in which a contact mechanism 50 provided on a base 10 is driven by a card 60 which slides and moves in parallel to the axis of an electromagnet block 20 provided in the base 10 as the electromagnet block 20 is magnetized and demagnetized, the base 10 comprises a guide portion 17 for restricting the card 60 in its position. This prevents variations in the performance characteristics so that high productivity and long service life of contacts can be obtained.

  • Gland sealing steam supply system for steam turbines
    Patent number: 4793141
    Abstract: In order to recover the heat of the waste gas from a gas turbine, a waste heat recovery boiler is provided, which has a high-pressure steam generating portion consisting of an economizer, a high-pressure steam generator and a superheater, and a low-pressure steam generating portion consisting of an economizer, and a low-pressure steam generator. The steam from the high-pressure generating portion is supplied to the turbine through a high-pressure steam pipe, and the steam from the low-pressure steam generating portion to the same through a low-pressure steam pipe. The high-pressure gland sealing steam is supplied to a high-pressure side steam gland portion the steam turbine through a high-pressure steam extracton pipe branching from the high-pressure steam pipe, a steam pressure regulator adapted to regulate the steam pressure and introduce the excess steam to a condenser, and a high-pressure gland sealing steam pipe.
