Abstract: A gap control part controls a clamping device so that mating surfaces in a die face each other across a gap, and thereby a cavity and an external part of the die communicate across the gap. A molten metal feed control part controls a molten metal feed device so as to feed molten metal into a sleeve when the gap is being maintained. An injection control part controls an injection device so as to start a forward movement of a plunger at a time when the gap is maintained and there is the molten metal in the sleeve. A clamping control part controls a clamping device so as to make the mating surfaces abut against each other to eliminate the gap after the forward movement of the plunger is started and before the molten metal reaches a molten metal surface height at which the molten metal flows into the gap.

Abstract: Provided is an electrically driven vehicle, wherein unexpected vibration or shock is prevented during interruption of torque transmission. An electric vehicle having an electric motor as its power source is provided with an F/F calculation or operation unit, an F/B calculation or operation unit, an adder, model determination units, and target torque value switching units. The F/F calculation unit calculates a first target torque value by F/F operation. The F/B calculation unit calculates a second target torque value by F/B operation using a model. The adder adds the first target torque value and the second target torque value, to obtain a motor torque command value. The model determination units evaluate whether or not an interruption in the torque transmission to drive shafts occurs. The target torque value switching units stop the F/F- and F/B operations while torque transmission interruption is confirmed.

Abstract: A rotary compressor for helium gas has a cylinder defining a closed space therein, a rotor disposed in the closed space for eccentric rotary motion while making a sliding contact with the inner peripheral surface of the cylinder, and a blade slidably mounted on the cylinder and resiliently projected into the closed space for sliding contact with the rotor so as to divide the closed space into a suction chamber and a discharge chamber. The compressor further has an oil relief passage which is arranged to allow the discharge chamber to communicate with a space outside the discharge chamber in the final stage of the discharging stroke before the crank angle of the compressor reaches an angle corresponding to the position of a discharge port.

Abstract: In a rotary compressor provided with a motor to be controlled by an inverter, the power-supply frequency or impressed voltage during one rotation of the induction motor is varied in accordance with the changes in the load torque to make the production torque of the induction motor correspond to the changes in the load torque so as to fundamentally and effectively reduce the oscillations which are caused by the load torque changes.

Abstract: A multi-vane type compressor formed with vane back pressure spaces having introduced thereinto a suction gas pressure in the suction and compression strokes and a discharge gas pressure in the discharge stroke. The compressor includes supply grooves for introducing the discharge gas pressure into the vane back pressure spaces, which are each split into a trailing side portion and a leading side portion. Each leading side portion for coping with the terminating stage of the discharge stroke is exposed to the discharge gas pressure via a passageway offering large resistance to the flow of fluid, to throttle the gas forced out of the vane back pressure spaces as the vanes are forced into vane grooves to thereby raise the vane back pressure. This is conducive to prevention of the jumping action of the vanes, and wear of the tips of the vanes and to minimization of vibration and noise.
