  • Patent number: 8351235
    Abstract: A feedback circuit by which an output of a memory device for storing level-shifted data can be fed back to the input side includes inverters, resistors, and transistors. The resistance value of combined resistance for pulling up or down first and second switching devices is varied in accordance with the output of the memory device by the feedback circuit, so that malfunction caused by dv/dt noise can be dealt with out generating any through current. In this manner, it is possible to provide a level shift circuit which can deal with malfunction causing dv/dt noise regardless of an on or off state of a high-potential-side switching device, while generation of a through current can be suppressed.

  • Patent number: 8347861
    Abstract: In a gas engine system, air fed through a turbocharger is mixed with fuel gas flowing through a fuel gas supply line and supply into a combustion chamber is controlled. In case that the fuel gas has a low calorie or the engine output power is high, a portion of the fuel gas is diverged from the fuel gas supply line, and the flow rate thereof is set to a constant rate less than that of the diverged side fuel gas. The diverging fuel gas is fed into the combustion chamber through a divergence control valve while the remainder of the fuel gas is fed into the fuel flow control valve. In case that the fuel gas has a high calorie or the engine output power is low, the divergence control valve is closed so as to feed the fuel gas only into the gas supply main pipe.

  • Patent number: 8338978
    Abstract: A wind power plant includes a wind turbine generator and an electrical storage device that supply electric power to a utility grid. A wind-turbine controller performs for the wind turbine generator an acoustic-noise suppression operation in which the rotational speed of blades is controlled in order to suppress acoustic noise, and also calculates a reduction in output power that is the difference in output power between the normal output power and the acoustic-noise-suppression output power. An electrical-storage-device controller causes the electrical storage device to be charged or discharged, based on the reduction in output power, the acoustic-noise-suppression output power, and the grid-demanded output power demanded from the utility grid. Therefore, the wind power plant can supply, to the utility grid, the electric power demanded from the utility grid even when the operation of suppressing the occurrence of acoustic noise is performed for the wind turbine generator.
