摘要:
A hydraulic device includes a cover plate with a cylinder hole opposite an end surface of a rotating shaft of a gear which receives two thrust forces in the same direction. A piston extends through the cylinder hole. A working liquid in a high pressure side acts on a back surface of the piston to press the piston onto the end surface of the rotating shaft, thereby causing a drag that cancels the two thrust forces acting on the gear.

Disclosed is an image processing apparatus in which, when the apparatus has not been not used for a prescribed period of time, control is performed so as to halt feed of current not only to a display unit and fixing heater but also to other components not required to operate when the apparatus is not in use, and in which on/off control of the power supply also can be performed through a more compact and less expensive arrangement. When a manually operated switch is being pressed by an operator, a transistor is turned on via the contacts of the switch so that power from a smoothing unit is applied to a regulator. The regulator supplies operating power to a microcomputer, which subsequently controls the status of the apparatus power supply depending upon the on/off state of an output port of the microcomputer. Supply of driving power to other components of the apparatus is achieved by opening and closing contacts through control of a relay in response to an output from another output port of the microcomputer.

An electronic apparatus includes a first switch for turning on/off a first power supply, a second switch for turning on a second power supply in response to an ON operation of the first switch, a communication unit for performing an image data communication with an external apparatus, and an operation holding unit for holding the ON operation of the first switch in response to an ON operation of the first power supply. The apparatus controls a holding operation of the operation holding unit, and the first and second switches, in accordance with a signal received via the communication unit.

A developer detecting device includes a developing unit for developing latent images with developer, a stirring unit for stirring the developer, a detector for detecting, during a stirring period, a decrease in the amount of developer and circuitry which outputs a signal detection only after a detection by the detector for at least one stirring period.

When the magnification is changed one or more times during the lens-moving period after a first magnification has been entered the last-entered magnification is made valid to prevent reproduction of an unwanted copy and to allow immediate reproduction of a desired copy. In an enlargement copying operation, the original is scanned for a length corresponding to a transfer paper sheet of a large size; in other copying operations, the original is scanned for a length corresponding to the size of the paper sheet. Over-heating of the original base is thus prevented during reproduction of copies of any size.

A stator for use in an electric rotating machine is provided which includes a stator winding wound through slots of a stator core. The stator winding is made up of a plurality of conductor segments connected together. Each of the conductor segments includes an in-slot portion disposed inside one of the slots and out-slot portions extending from the in-slot portion outside at least one of the ends of the stator core. Ends of the out-slot portions are joined together to form the stator winding. The joints of the ends of the out-slot portions have a given pattern of texture formed on surfaces thereof and coated with an insulating material. The pattern of texture enhances the adhesion of the insulating coatings to the surfaces of the joints and ensures the stability in electric insulation of the joints.

A method for welding copper includes steps of spraying an inert gas to copper that is an object to be welded to cover a portion to be welded on the copper with the inert gas, and performing electrical discharge to weld the portion to be welded. The inert gas that covers the portion to be welded passes a dehumidifying process that removes moisture contained in the inert gas.

A broadcast receiving terminal having a calculating process unit operated at different clock frequencies in response to modes executes a mode switching method comprising the below-mentioned steps. The mode switching method is comprised of: a step for judging whether or not a mode switching instruction is issued while the calculating process unit is operated; a step for setting the calculating process unit to an idling status when the mode switching instruction is issued; and a step for releasing the idling status of the calculating process unit.

A light quantity controller and an input device are disclosed. The light quantity controller comprises a light source, a photo-sensor to detect a light quantity of the light source, a signal source for generating a reference signal, a comparator for comparing the detected light amount with the reference signal, and control circuit to control a duty ratio of the energization to the light source in accordance with the compare result to maintain the light quantity of the light source at a constant level. The light quantity controller further comprises a comparator to compare the energization signal to the light source with a reference signal to detect the degradation of the light source. The input device has a key matrix including a plurality of input ports and a plurality of output ports of a control unit interconnected through switches. A signal source independent from the output ports of the key matrix is connected to at least one of the input ports through switches.

A hydraulic device at least has a pair of helical gears 20, 23, a body 3 containing the gears, bearing members 40, 44 supporting rotating shafts 21, 24 of the gears 20, 23, and cover plates 7, 8, 11 liquid-tightly fixed to both end surfaces of the body. The cover plate 8 has a cylinder hole 8a formed at a portion opposite to an end surface of the rotating shaft 21 of the gear 20 which receives two thrust forces Fma, Fpa in the same direction, and a piston 9 is inserted through the cylinder hole 8a. A working liquid in a high-pressure side is caused to act on a back surface of the piston 9 and thereby the piston 9 is pressed onto the end surface of the rotating shaft 21, thereby causing a drag almost balancing a resultant force of the two thrust forces Fma, Fpa to act on the rotating shaft 21. The thrust forces Fma, Fpa acting on the gear 20 are cancelled by this drag.
