Abstract: A vehicle driving apparatus (1) integrates an electric motor (10) that is a drive source of a vehicle (100), a power conversion device (30) that is electrically connected to the electric motor (10), and a power transmission mechanism (50) that transmits rotation of power from the electric motor (10). An axial direction of a rotating shaft of the electric motor (10) is arranged in a vehicle width direction. The power conversion device (30) and the power transmission mechanism (50) are respectively arranged on one side and the other side of the electric motor (10) in the vehicle width direction. The power conversion device (30) is provided with a connector part (39) to which power wiring (40) is connected. The connector part (39) is arranged to draw out the power wiring (40) from the power conversion device (30) in the vehicle width direction.

Abstract: “A controller of a corrugated fiberboard sheet manufacturing apparatus can execute a steady operation where a corrugating roll rotates at a first set speed, a deceleration operation where the corrugating roll is decelerated to a second set speed, and an acceleration operation where the corrugating roll is accelerated to a third set speed. In the steady operation, the controller set an on-off valve to a closed state for steam supply to a hollow portion at a first set pressure by a pressure adjusting valve. In the deceleration operation, the controller maintains states of the valves. In the acceleration operation, the controller switches the on-off valve to an open state, and adjusts the pressure adjusting valve for steam supply to the hollow portion at a second set pressure.

Abstract: A rotating electric machine includes: a cylindrical stator core which includes a plurality of slots; a coil which includes a first coil end inserted into the slot and protruding toward one side of the stator core in an axial direction and a second coil end protruding toward the other side in the axial direction; a rotor which is disposed coaxially with the stator core; a shaft which is disposed coaxially with the rotor; and an end wall which is provided at an end side of the shaft and faces the first coil end in the axial direction. The end wall includes a refrigerant outlet which opens in the axial direction so that a refrigerant supplied from the outside is ejected toward the first coil end.

Abstract: A driving system includes: a left electric motor which drives a left wheel of a vehicle; a first parking gear which is provided on a left power transmission path between the left electric motor and the left wheel; a right electric motor which drives a right wheel of the vehicle; a second parking gear which is provided on a right power transmission path between the right electric motor and the right wheel; and a rotation regulation unit that engages with both of the first parking gear and the second parking gear. The first parking gear and the second parking gear have different tooth tip diameters.

Abstract: In a drain recovery section including a recovery tank to which drain generated in a steam-using device is collected and from which the drain is supplied to a boiler, pressure decrease in the boiler under a high load can be suppressed. A drain recovery section includes: a recovery tank in which drain generated by condensation of steam in a steam-using device is stored and from which water stored in the recovery tank is supplied to a boiler; and a control unit that controls an amount of water supply from the recovery tank to the boiler to prevent the water level of water in the recovery tank from decreasing below a predetermined tank reference water level. When the load of the boiler increases to a predetermined load, the control unit reduces the tank reference water level by a predetermined amount.
