    摘要: A high-pressure, dome-type compressor includes a DC motor 5 having a rotor 5a that uses a rare earth/iron/boron permanent magnet having an intrinsic coercive force of 1.7 MA.m−1 or greater in a rotor thereof and has a rated output or 1.9 kW or higher. The motor, which drives a compression element 3 in a casing 2, is disposed in a high pressure, high temperature area 6, which is filled with gas discharged from the compression element. An inverter 10 controls current supplied to the motor such that the motor temperature becomes equal to or less than a predetermined temperature and an opposing magnetic field generated in a stator has a predetermined strength or less. Since the magnet does not reach a high temperature and is not exposed to a strong opposing magnetic field, it is hardly demagnetized. As a result, performance of the motor and of the compressor is stable.

    摘要: Spiral fixed scroll teeth (2a) project from an end plate (2b) of a fixed scroll (2), and spiral movable scroll teeth (4a) project from an end plate (4b) of a movable scroll (4). The end plate (4b) of the movable scroll (4) is provided with a discharge port (8) for discharging compressed refrigerant gas. A pressure chamber (16) is provided on the back surface of the end plate (2b). A port (10) communicating with the pressure chamber (16) is provided on a position of the end plate (2b) opposed to the discharge port (8). Thus obtained is a scroll compressor reducing pulsation when discharging a fluid by feeding the compressed fluid into the pressure chamber.

    摘要: A plurality of compression chambers are formed between first and second spiral bodies 1 and 2, and refrigerant discharge timing advancing means is provided for advancing the timing at which refrigerant is discharged from a first compression chamber 4 which is one of a pair of compression chambers located nearest to the center, relative to the refrigerant discharge timing of the second compression chamber 5. The refrigerant discharge timing advancing means includes an extension 1c of the first spiral body 1 and an opening advancing portion 3a of a discharge port 3.

    摘要: After analog-to-digital conversion, a luminance signal 103 and a chrominance signal 109 are stored in a line memory circuit 128. Such stored signals are read out of said line memory circuit, using a read clock 124 obtained by parabolically modulating a read frequency with both the horizontal period and the vertical period. The read-out digital signal is again converted into an analog luminance signal 132 and analog color difference signals 135, 136 by digital-to-analog conversion. By this procedure, inner pincushion distortion or inner barrel distortion is corrected. Since such distortion is corrected by modulating an image signal itself by digital processing, no circuit drift due to the conventional analog correction occurs and no analog circuit design such as troublesome setting of parts constants is required.

    摘要: A mold includes a first groove part and a second groove part. The first groove part extends with a constant length or a constant width from a center part to an outer circumferential part of the mold. The second groove part extends from a terminal end of the first groove part on an outer circumferential part side of the first groove and merges with any portion of the first groove part. A molding manufacturing method includes manufacturing a preform by semimolten die casting or semisolid die casting using the mold. The method may also include removing a portion of the preform corresponding to the second groove part.
