Abstract: A liquid recovery device includes: an outer pipe that includes an introduction portion into which a gas-liquid two-phase fluid is introduced; an inner pipe disposed inside the outer pipe at a position where the introduction portion is extended to a downstream side in a flow direction of the gas-liquid two-phase fluid; a double pipe portion that includes a clearance part provided between an inner side of the outer pipe and the inner pipe at a downstream side of the outer pipe in the flow direction; a communication hole that communicates the inner side of the inner pipe with the clearance part; and a drainage portion connected to the clearance part to discharge the liquid-phase fluid flowing into an interior of the clearance part.

Abstract: An energy conversion system includes an energy converter, a cold generator, and a liquid water obtainer. The energy converter is configured to convert energy of a source from one form to another form and generate heat and water vapor. The cold generator is configured to generate cold using the heat generated by the energy converter. The liquid water obtainer is configured to condense the water vapor using the cold to obtain liquid water. Accordingly, the water vapor generated from the energy converter can be cooled efficiently. Therefore, efficiency in obtaining the liquid water can be improved compared with a case where the water vapor is cooled by open air.

Abstract: A vehicle driving system control apparatus includes a power transmission device and a power transmission control section. The power transmission device includes an engine input shaft, a motor input shaft, an output shaft, an engine-side gear mechanism transmitting a power of the engine input shaft to the output shaft, a motor-side gear mechanism transmitting a power of the motor input shaft to the output shaft, a first clutch enables and disables a power transmission between the engine input shaft and the motor input shaft, a second clutch enables and disables a power transmission between the motor-side gear mechanism and the output shaft, and a third clutch enables and disables a power transmission between the engine-side gear mechanism and the output shaft. The power transmission control section determines statuses of the clutches and required torques of motor generators in correspondence with a rotation speed of an axle.

Abstract: A drive control apparatus includes a motor control unit and a gear shift control unit, and controls a power transmission system including first and second motors and a gear shift mechanism. When the gear shift mechanism is changed from a first gear stage to a second gear stage during deceleration of the vehicle, the motor control unit controls the first motor to be at a target rotation speed determined based on a gear ratio of a second power transmission gear and a rotation speed of an output shaft, and controls a second motor such that required brake torque is generated by the second motor. The gear shift control unit controls the gear shift mechanism so as to be in a neutral state in which power is not transmitted between an input shaft and the output shaft, until a rotation speed of the first motor becomes the target rotation speed.

Abstract: A vehicle driving system control apparatus includes a regeneration control section that performs a regeneration control when a vehicle is decelerated. In the regeneration control, the regeneration control section drives at least one of a first motor generator and a second motor generator with a power of an axle so as to charge a battery with an electric power generated with the at least one of the first motor generator and the second motor generator. The regeneration control section selects a mode of the regeneration control by controlling engagement and disengagement statuses of first to third clutches in correspondence with at least one of a target energy regeneration amount, a required brake torque and a vehicle speed.
