An actuator of a variable valve operating device includes an electric motor for varying the distance by which an intake valve of an internal combustion engine is lifted. The electric motor has a hollow cylindrical magnet assembly disposed around a hollow cylindrical holder, and a shaft rotatably supported in a housing, with a hollow region being defined between the shaft and the holder. The magnet assembly is skew-magnetized at a predetermined angle to the axis of the magnet assembly.

A laser beam printer capable of changing the printing speed and quality. The laser beam printer includes a speed decoding unit for decoding a specification of the printing speed, and a speed setting unit for setting a transport speed for a sheet of paper taken as an object of recording in accordance with decoded contents of the printing speed.
摘要:
An image forming apparatus having a built in AC voltage control circuit which enables the apparatus to be used in regions of the world having commercial power supplies with different supply voltages. The AC voltage control circuit first compares the input voltage to a reference voltage and then performs a switching operation to ensure that the voltage supplied to the AC electric components of the image forming apparatus is the voltage necessary for operation of those components.

A vehicle includes an internal combustion engine that generates power for rotating drive wheels, a differential mechanism that is provided between the engine and the drive wheels, and has at least three rotary elements including a first rotary element coupled to the engine, and a second rotary element coupled to the drive wheels, and a controller configured to control the engine. The controller is configured to determine whether to perform correction to increase the power generated by the engine, or perform correction to reduce the power, depending on a rotational speed of the second rotary element, when it changes a rotational speed of the engine.

A hybrid vehicle includes an electric steplessly speed changing unit, an engaging device, and an electronic control unit. The electric steplessly speed changing unit includes a differential mechanism including a first rotary element to which an engine is coupled, a second rotary element to which a first rotary machine is coupled, and a third rotary element as an output rotary member of the differential mechanism to which a second rotary machine is coupled. Differential operation of the electric steplessly speed changing unit is controlled by controlling operation of the first rotary machine. The engaging device is provided in a power transmission path between the third rotary element and drive wheels. In control of the hybrid vehicle, when at least one of the first rotary machine and the second rotary machine is operated with a predetermined positive or negative maximum torque, the electronic control unit controls a slip amount of the engaging device by changing the torque capacity of the engaging device.

If an accelerator pedal is released, when a flag indicates 1, a vehicle travels in a traveling environment reflected operation mode where an engine and two motors are controlled in a manner that a required torque is output to a drive shaft while the engine is operated by the motor. If a vehicle speed is equal to or lower than a threshold at the time or after the flag is changed from 1 to 0, the vehicle travels in a normal operation mode where the engine and two motors are controlled in a manner that the required torque is output to the drive shaft with engine rotation stopped. If the vehicle speed is higher than the threshold when the flag is changed from 1 to 0, the vehicle travels in the traveling environment reflected operation mode until the vehicle speed becomes equal to or lower than the threshold.

Disclosed is a heater control device which controls a heater used in an image forming apparatus such as a laser printer, a copying machine, or a facsimile machine. The heater control device includes a switch for connecting and disconnecting an application of an alternating current voltage to the heater used in the image forming apparatus, and a switch control unit for varying a period of time for the application of the alternating current voltage to the heater per unit period of time by controlling the switch in accordance with a value of the alternating current voltage applied to the heater. The heater control device can be used regardless of the differing voltage levels of available commercial power provided in various geographic regions of the world respect to voltage.

A control apparatus for a vehicle including a differential section having a first rotating element coupled to a prime mover and a second rotating element connected to drive wheels via an engaging and disengaging apparatus, including: a controller configured to control connection of the engaging and disengaging apparatus, the controller being configured to adjust a power of the prime mover, the controller being configured to reduce the power of the prime mover when performing connection of the engaging and disengaging apparatus, and the controller being configured to reduce more power of the prime mover as a speed of rotation of the first rotating element is lower.
摘要:
A vehicle includes a transmission between an engine and a drive wheel and includes a differential mechanism (planetary gear mechanism) between the engine and an engagement device (transmission). A controller (ECU) included in the vehicle calculates a variation rate in the whole rotation energy of the planetary gear mechanism when it is in the inertia phase of a shift. The ECU increasingly corrects an engine generated power and decreasingly corrects a transmission transfer power when the variation rate is higher than 0. The ECU decreasingly corrects the engine generated power and increasingly correct the transmission transfer power when the variation rate is lower than 0.

If an accelerator pedal is released, when a flag indicates 1, a vehicle travels in a traveling environment reflected operation mode where an engine and two motors are controlled in such a manner that a required torque is output to a drive shaft while the engine, in which fuel injection is stopped, is operated by the motor. If a vehicle speed is equal to or lower than a threshold at the time or after the flag is changed from 1 to 0, the vehicle travels in a normal operation mode where the engine and the two motors are controlled in such a manner that the required torque is output to the drive shaft with engine rotation stopped. If the vehicle speed is higher than the threshold when the flag is changed from 1 to 0, the vehicle travels in the traveling environment reflected operation mode until the vehicle speed becomes equal to or lower than the threshold.
