    摘要： A fixing device receives a recording material having a toner image and applies pressure and heat to fix the toner image. The fixing device includes a fixing member, a sliding member, a pressing member, and a heating member. The fixing member has a rotatable endless belt shape that includes an inner circumferential resin layer. The sliding member is pressed against the inner circumferential surface of the fixing member with a lubricant interposed between the sliding member and the inner circumferential surface. The sliding member has a resin coating layer and slides on the inner circumferential surface. The pressing member presses the recording material toward an outer circumferential surface of the fixing member. The heating member generates heat to heat the recording material. A surface hardness of the inner circumferential surface of the fixing member is smaller than a surface hardness of the sliding surface of the sliding member.

    摘要： Fluctuations in output of an AC electric motor are restrained without increasing electromagnetic noise of a boost converter. When subjecting the AC electric motor to rectangular wave voltage control, output torque T is controlled by varying a voltage phase φv. In a region where a voltage phase is large (φv=θ2), fluctuations in torque T relative to changes in a DC voltage VH corresponding to the amplitude of a rectangular wave voltage are larger than in a region where the voltage phase is small (φv=θ1). The AC electric motor is controlled such that the rectangular wave voltage control in a region where voltage phase φv is larger than a limit-phase line PLN indicated by a set of limit phases set for each DC voltage VH is avoided.

    摘要： An electrically powered vehicle includes a motor generator configured to be capable of transmitting and receiving torque to and from a driving shaft coupled to a driving wheel; a DC power supply including a power storage device; and an inverter for performing bidirectional DC/AC power conversion between the DC power supply and the motor generator. The MG-ECU controls a plurality of power semiconductor switching elements to be turned on/off in accordance with a torque command value and a state value of the motor generator. When an accelerator pedal is released, the MG-ECU controls the inverter to superimpose a DC current component on an AC current of each phase in the motor generator in accordance with the state of charge of the power storage device.
