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 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.

摘要： A semi-molten or semi-solid molding method is used to cast a scroll member having a tabular panel, a spiral section, and a columnar part. The method includes filling a cavity formed inside of the molding die with semi-molten or semi-solid metal from a section for forming the columnar part via a runner that forms a channel. The cavity forms a space for casting the scroll member. An angle of intersection θ1 between the runner and the section for forming the columnar part is set such that to 97°≦θ1≦135°, and/or a ratio R/√S is set such that 0.12≦R/√S≦0.96. R is a radius of curvature of a chamfered section in which the runner intersects the section for forming the columnar part, and √S is the square root of a cross-sectional area S of the section for forming the columnar part.
