  • Publication number: 20130257371
    Abstract: A battery module charging system includes a power transmitting device, including a primary coil configured to transmit AC power, and a power receiving unit, including a secondary coil configured to receive the AC power transmitted from the primary coil by electromagnetic induction. The power receiving unit is configured to convert the received AC power into DC power. A positioning mechanism is configured to allow the power transmitting device to be detachably attached to the power receiving unit and to position the primary and secondary coils such that the coils are allowed to be electromagnetically coupled to each other when the power transmitting device is attached to the power receiving unit. Further, a selection circuitry is configured to selectively charge a plurality of cells in a battery module with the DC power. The plurality of cells, the cells being secondary batteries, are connected to each other in a series.

  • Publication number: 20060201155
    Abstract: In a steam turbine plant in which a turbine casing containing a turbine is constituted of an upper-half casing and a lower-half casing, nozzles are provided to the upper-half casing and a steam supplied through main steam piping lines are delivered into the upper-half casing. Main steam pipes for supplying a steam from respective main valves to the respective nozzles are each formed so as to be dividable in a position out of the installation area of the upper-half casing.

  • Publication number: 20030061796
    Abstract: A power generating plant comprises: a boiler; a steam turbine to be driven with steam generated in the boiler; a power generator to be driven according to the rotation of the steam turbine; a strut for supporting the boiler; a base mounting the steam turbine thereon; and a frame for supporting the base. The steam turbine is disposed above the boiler, and the strut for supporting the boiler is used as the frame. Thus, it is possible to package the steam turbine equipment and the boiler, thereby reducing a construction site for the power generating plant.

  • Patent number: 6250068
    Abstract: According to the present invention, the shape of a passage in an intake-air duct communicated with the suction side of the intake-air filter is regulated so that snow is heaped up in the intake-air duct, and accordingly, the volume of snow reaching the intake-air filter is reduce in order to prevent the intake-air filter from clogging, and to prevent the flow rate of intake-air into a gas turbine from being lowered. In order to attain the above-mentioned purpose, there is provided, according to the present invention, an air-intake method for a gas turbine, in which intake-air 18 taken from a fresh air intake port is fed downward through a second intake-air duct in a substantially vertical direction, and then is fed in a substantially horizontal direction. Thereafter, dust is removed from the intake-air within an intake-air filter chamber, and then, is led into the gas turbine.
