Abstract: A stator includes an annular stator core and a stator coil. The stator core has a plurality of slots formed therein. The stator coil includes first to third phase windings mounted on the stator core and a connection portion located outside the slots of the stator core. The connection portion is formed of a first connection wire connecting the first and second phase windings and a second connection wire connecting the third phase winding to the first connection wire. The first connection wire is arranged so as to extend in the circumferential direction of the stator core. The second connection wire is bent to include a bend and an intersecting part that extends from the bend to the first connection wire so as to intersect the first connection wire. The intersecting part of the second connection wire is joined to the first connection wire with a joint formed therebetween.

Abstract: A pair of meshed gears is disposed in a hydraulic chamber of a housing. Bushes in the chamber contact both end surfaces of the gears. Edge surfaces of the gears are chamfered at intermediate parts between tooth tips and tooth bottoms, and the inclination of the intermediate parts is larger than those of the tooth tips and bottom, thereby protecting the edges from damage due to contact force as the gears mesh and preventing leakage between the gears and the support members. Accordingly, the gears may be operated quietly, at high output efficiency, and increased reliability for an extended period.

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.

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.

Abstract: A base metal composed of a plurality of metallic materials having an oxygen content of 10 ppm is first preheated partly or overall. Then AC (alternating current) current is made to pass through the preheated base metal and an electrode so as to generate an arc for welding the metallic materials. The waveform of the current is changed with time between a peak current value and a base current value excluding a current of zero value only in one of plus and minus polarity sides of the current. A current ratio defined by dividing a current amplitude between the peak and base current values by a current average of the alternating current is a range of 0.5 to 2.0. The alternating current has a frequency of 500 Hz or higher.

Abstract: 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.

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.

Abstract: A reproducing device and method not producing any abnormal sound in fast-forward reproduction and rewind-reproduction modes and not causing any delay in a reproduction mode. In the reproducing device and method a music reproducing circuit (200) comprises a silence encoding data storage section (201) storing encoded silence data created by encoding silence by means of AAC, data selecting section (202) for selecting one of the encoded silence data and coded data inputted from outside and transmitting the selected data to a decoding section (203), and the decoding section (203) for decoding AAC coded data and generating a sound signal. By decoding the encoded silence signal at a point where the frames are discontinuous in the fast-forward reproduction mode, fade-in or fade-out is carried out at the frame discontinuous point.

Abstract: A method for manufacturing a winding for an electric rotating machine includes steps of altering, passing, shaping, and connecting. In the altering step, connecting portions of conductor segments, a part of which is exposed, are altered in shape by a pressing die to provide good contact between the segments when they are connected. The altered segments are passing through slots of a stator core in the passing step. Ends of protruded portions of the segments are shaped so that they make an angle with respect to the radial section of the stator core in the shaping step. Adjacent segments are connected together at ends of the connecting portion in the connecting step.

Abstract: An image processing apparatus structured by combining an image reading apparatus and an image formation apparatus with each other enables a user to freely combine these apparatuses without considering the sum of power consumption of the image reading apparatus and power consumption of the image formation apparatus. When the sum of power consumption of a reader unit and power consumption of a printer unit exceeds, e.g., 1.5 kW, the reader unit is set to be in a low power consumption mode such that the sum of power consumption becomes equal to or smaller than 1.5 kW. Even when the low power consumption mode of the least power consumption quantity is selected and the sum of power consumption still exceeds 1.5 kW, use of the apparatus is inhibited and the inhibition is displayed.

Abstract: An apparatus and method that reproduces a voice signal at different rates without a change in pitch. Neighboring voice waveforms having a same length and minimum form differences from an input voice signal are selected and overlapped. An output voice waveform is then generated that is rate converted by replacing a part of the voice waveform of the input voice signal with the overlapped voice waveforms, or, alternatively, by inserting the overlapped voice waveforms into the voice waveform of the input voice signal.

Abstract: The present invention can obtain a clear velocity converted sound in a sound signal which is recorded in recording media, without changing an interval of the sound signal. An input sound signal (1a) is transmitted from a sound signal storage memory (1) to a voiced sound/unvoiced sound deciding portion (2). In the voiced sound/unvoiced sound deciding portion (2), it is decided whether the input sound signal (1a) is a voiced sound or an unvoiced sound. A decision result is transmitted to a speech velocity converter (4) as a switching flag (1b). The speech velocity converter (4) outputs the unvoiced sound as it is. A predetermined windowing and adding processing is performed to the voiced sound, a time compression is carried out so as to output the voiced sound. An output signal (1e) from the speech velocity converter (4) is output as a frame output signal (1g) through an output sound signal frame buffer (8). In another mode, a switch and an adder may be used.

Abstract: 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.
