A liquid pressure generating apparatus including a pump; and two one-way clutches arranged coaxially with the pump's drive shaft. Inner races of the respective two one-way clutches are integrated with each other to form a common inner race. Outer races of the respective two one-way clutches are formed independently from each other and are driven respectively by pump driving members different from each other. The common inner race includes a coupling portion coupled to the pump drive shaft and extending in the radial direction and a cylindrical body portion extending from the coupling portion in a second axial direction opposite from the first axial direction on the radially outside the pump drive shaft. The body portion includes a depression indented radially outward on an inner peripheral surface thereof. A lubricant supply portion for the depression is provided radially inside the depression.

An image forming apparatus includes a photoconductor, an optical scanner, a development device, a movable density sensor, a density sensor driver, and a processor. The optical scanner includes a light source to emit light, and irradiates a surface of the photoconductor in a main scanning direction with the light to form a latent image on the surface of the photoconductor. The development device develops the latent image into a toner image. The density sensor detects unevenness in density of the toner image in the main scanning direction. The density sensor driver moves the density sensor in the main scanning direction. The processor corrects a driving signal for the light source according to image data to reduce the unevenness in density in the main scanning direction, according to positional data of the density sensor in the main scanning direction and an output value of the density sensor.

A planetary gear unit inside a case includes coaxial sun and ring gears, a planetary pinion gear that meshes with the sun and ring gears, and a carrier that holds the planetary pinion gear, the ring gear being fixed with respect to the case, and a flange disposed inward of the ring gear. The ring gear is fixed to a case wall, via the flange, the wall extending radially inward, and the flange being prevented from rotating with respect to the wall by a rotation prevention mechanism. The rotation prevention mechanism includes a plurality of case holes on the same circle in the wall, flange holes in the flange at positions corresponding to the case holes, and rotation prevention members fitted into the case and flange holes to prevent rotation of the flange with respect to the wall with the flange relatively movable axially with respect to the wall.
摘要:
A high-power laser unit capable of accurately correcting laser output from low to rated outputs, even when the laser unit has a laser power monitor which may be affected by environmental factors inside or outside the laser unit, by effectively reducing environmental factors. The laser unit has a laser power monitor for measuring laser output, and a laser controller for correcting the laser output by correcting an amount of excitation energy to a laser power supply so that a measurement value coincides with a laser output command value. The laser unit has a laser output commanding part for generating a laser output command. When it is not necessary to correct the laser output command, the laser output command is converted into an excitation energy command value and sent to the power supply. Otherwise, an output correcting part of the laser controller corrects the laser output command.

A control device includes a device state changing unit, a communication unit, a communication unit, a storage unit, a storage unit state changing unit, and a reducing unit. The device state changing unit changes a state of the control device between a power saving state and a normal state. The communication unit communicates with a controlled device. The storage unit is an object of at least one of reading operation and recording operation by the communication unit. The storage unit stores at least part of information which the communication unit needs for communication with the controlled device. The storage unit state changing unit changes a state of the storage unit between a stored content holding state and a normal state in given cycles. The reducing unit reduces frequency of operation of reading and recording to the storage unit in the communication unit.

The control apparatus acquires an ideal velocity characteristic of a control surface, and the temperature of pressure oil of the actuator to be tested and the operating speed of the control surface when the actuator is attached to the control surface. The control apparatus corrects the ideal velocity characteristic of the control surface by using the pressure oil temperature and the control surface operating speed. The control apparatus sets an upper limit and a lower limit by using a predicted value for a fluctuation range for a fluctuation factor that causes a fluctuation of the control surface operating speed, with reference to the corrected ideal velocity characteristic, measures the pressure oil temperature and the operating speed by actuating the control surface, with the actuator to be tested placed in a damping mode, and determines whether the measured value falls within the range between the upper limit and the lower limit.
