  • Patent number: 11493240
    Abstract: The amount of consumption of gas is reduced when the gas is expanded to be cooled by using a plurality of expansion turbines. A high-pressure expansion turbine includes: a gas supply passage through which bearing gas is supplied to a bearing portion; and a gas discharge passage through which the bearing gas which has been supplied from the gas supply passage to the bearing portion is discharged from the bearing portion. A low-pressure expansion turbine includes: a gas supply passage through which the bearing gas is supplied to a bearing portion; and a gas discharge passage through which the bearing gas which has been supplied from the gas supply passage to the bearing portion is discharged from the bearing portion. The bearing gas discharged from the gas discharge passage of the high-pressure expansion turbine is supplied to the gas supply passage of the low-pressure expansion turbine.

  • Patent number: 11331798
    Abstract: A robot system includes: a robot; a portable operation terminal having a teaching function; and a robot controller having operation modes including a teaching mode and another operation mode different from the teaching mode, the teaching mode being an operation mode for teaching a motion to the robot through the portable operation terminal. The robot controller is configured to: detect electrical connection and electrical disconnection between the robot controller and the portable operation terminal; change an operation mode in which to operate the robot to the teaching mode when detecting the connection between the robot controller and the portable operation terminal; and change the operation mode in which to operate the robot to the other operation mode different from the teaching mode when detecting the disconnection between the robot controller and the portable operation terminal.

  • Patent number: 10358961
    Abstract: An exhaust apparatus for a diesel engine rapidly burns an unburned deposit in an upstream exhaust catalyst with heat of a heater. The exhaust apparatus includes a downstream exhaust cleaner, an upstream exhaust catalyst provided in an exhaust passage, upstream of the downstream exhaust cleaner, a heater disposed at an exhaust inlet of the upstream exhaust catalyst, and an engine starter apparatus. A control unit controls the power supply to the heater and an engine start process is performed by the engine starter apparatus. A start command unit is connected to the control unit. When the engine has been stopped and then the start command unit gives the control unit a start command, the control unit powers the heater without performing an engine start process, thereby keeping the engine stopped for a predetermined period of time after the start command has been given, and subsequently performing the engine start process.
