  • Patent number: 10690242
    Abstract: An abnormality determination device of a lock up clutch includes a controller and a determining unit. The controller sets a lock up clutch in a torque converter at an engaged state or a disengaged state. The torque converter is provided in an automatic transmission of a vehicle. The determining unit determines, on the condition that deceleration of the vehicle on travel with the lock up clutch in the engaged state causes a control signal for disengagement to be outputted from the controller, the presence or the absence of the abnormality in the lock up clutch, on the basis of a determination result as to whether or not a difference between the number of engine rotations and the number of turbine rotations is equal to or larger than a first threshold that varies with a rate of deceleration of the vehicle.

  • Patent number: 10641170
    Abstract: One of the objects of the invention is to provide a water-saving type advanced humid air gas turbine system (AHAT) that can decrease the amount of makeup water to be supplied from the outside, by reducing the amount of water consumed when the gas turbine system is starting up, shut down, or subjected to load rejection. The gas turbine system includes a compressor, the compressed air header for generating humidified combustion air, a combustor for generating combustion gas, and the turbine. When the gas turbine system is starting up, shut down or subjected to load rejection, steam coming from the heat recovery steam generator is recovered by blocking the first steam system and making the second steam system communicate with the heat recovery steam generator.
