  • Patent number: 8793045
    Abstract: A hybrid drive device includes a speed change mechanism, a motor drivingly coupled to an input shaft, and a clutch interposed between an engine and an input shaft. Upon engine start during engine traveling, the clutch is engaged, and rotation of the engine is increased. A control device of the hybrid drive device includes start upshift control means that, according to the engagement control of the clutch upon engine start, upshifts the speed change mechanism to output inertia torque. Thus, when the engine is started, output torque as the sum of driving torque of the motor and the inertia torque is output to the driving wheel, which reduces hesitation upon engine start.

  • Patent number: 8335603
    Abstract: Upon the occurrence of the abnormality that the inverter for driving the motor is in the one-phase short circuited state, this inverter is stopped in the three-phase short circuited state and sets the execution torque by subtracting the counter electromotive force application torque that is applied the driveshaft due to the counter electromotive force generated by rotation of the motor and the steering angle application torque corresponding to the steering angle from the torque demand according to the step-on amount of the accelerator pedal. The engine and the inverter for driving the motor is controlled so that the vehicle is driven with the set execution torque. This enables the driving force output to the driveshaft from the engine and the motor to be in accordance with the torque demand.

  • Patent number: 8192193
    Abstract: A notched region in which the outer periphery of a screw flight is cut out is provided in a molding material feed screw. A wedge-shaped portion is formed by both a front wall surface of the screw flight and a wall surface of the boundary where the outer periphery of the screw flight is cut out. As a result of rotation of the molding material feed screw, since the wedge-shaped portion advances while pushing aside resin pellets located in the front thereof in two lateral directions of the front wall surface of the screw flight and the wall surface of the boundary where the outer diameter of the screw flight is cut out, entrapment of the resin pellets between the edge of a material supply port of a molding material supply device and the outer periphery of the screw flight is avoided as much as possible.

  • Patent number: 7758328
    Abstract: Screw rotation speeds and screw rotating torques are measured at predetermined time intervals during metering and substituted into a previously-assumed function to determine a maximum screw rotating torque at each screw rotation speed. An allowable upper limit of screw rotating torque is set for each screw rotation speed on the basis of the determined maximum screw rotating torque. If a screw rotating torque exceeding the allowable upper limit is detected during metering after the allowable upper limit is set, the screw rotation is stopped or changed.
