Abstract: A scroll compressor, whose back pressure is easily controlled and compression efficiency is high, is provided. The scroll compressor includes a plurality of compression chambers formed by engaging a fixed-scroll wrap and a orbiting-scroll wrap, and a back pressure chamber formed at an opposite side of the orbiting-scroll wrap of a orbiting-scroll. The scroll compressor additionally includes a high pressure chamber and a middle pressure chamber, which are formed by dividing the back pressure chamber using a seal. Moreover, the scroll compressor includes a first path for supplying lube oil from the high pressure chamber to the middle pressure chamber, and a second path for supplying the lube oil from the middle pressure chamber to an suction chamber of the compression chambers. The first path is intermittently opened by orbit of the orbiting-scroll.

Abstract: Preferred embodiments of this invention provide a base station and a terminal appropriate for a protocol for realizing a high performance and a low delay by relaying in a base station only if a direct transmission is not performed between terminals and omitting a data transmission channel for relaying if the direct transmission is performed. When a receiver terminal receives data directly from a sender terminal, the receiver terminal transmits a report of a direct receipt of the data to the base station. When the base station receives the report of the direct receipt of the data, the base station omits the data transmission channel for relaying.

Abstract: A hermetic type compressor comprises a hermetic container in which a compressor mechanism and a motor are provided, and a rotor of the motor is comprised of laminated iron plates in which permanent magnets are embedded, and a main shaft of the compressor mechanism is inserted into the rotor over its entire length.

Abstract: The object of the invention is to provide an information processing technology for realizing more efficient physical distribution. Schedule information regarding a form of receiving (for example, “not available for receiving”, “available for receiving”, “forward”, “kept until called for”) a package addressed to the member is received from a terminal of a member and then is registered in a storage device. Further, a delivery form (for example, deliverable or not deliverable for “not available for receiving”) is determined with reference to at least the receiver's schedule stored in the storage device if the receiver is a member. Then, delivery request information for the distributor is generated in accordance with the delivery form if the determined delivery form involves a movement of the package. Accordingly, since a member registers his form of package receiving by himself in advance, he can receive the package in accordance with his schedule.

Abstract: A hermetic compressor includes a plurality of compressing mechanisms. Each of the compressing mechanism includes a rotary cylinder having a groove, and a piston slidable in the groove, so that a compressing stroke is carried out by rotation of said piston on a locus of a radius E about a point spaced apart at a distance E from the center of said rotary cylinder. A partition plate is interposed between the rotary cylinders of the adjacent compressing mechanisms. The partition plate is provided with a communication bore through which a shaft is passed. The partition plate is provided with cranks on which said pistons can be mounted. A motor mechanism section is adapted to drive the pistons of the compressing mechanisms by the common shaft. At least one of the compressing mechanisms is different in phase in a compressing stroke from the other compressing mechanisms.

Abstract: A hermetic compressor includes a compressor mechanism section 40 which includes first and second rotary cylinders 41a and 41b, and first and second pistons 42a and 42b eccentrically rotated in first and second grooves 42a and 43b in the first and second rotary cylinders 41a and 41b, upper and lower bearings 50a and 50b which clamp the first and second rotary cylinders 41a and 41b, and a casing 51. A projection, 64, a projection 66 or a recess 67 is formed on slide faces in the components of the compressor mechanism section 40, whereby the power loss due to the viscosity is reduced remarkably by reducing the sliding area of the slide faces. Thus, the efficiency of the compressor can be enhanced, and the inclination and the eccentricity of the rotary cylinder can be suppressed to the minimum.

Abstract: In a scroll compressor, a stationary scroll is pressed toward a movable scroll by a back pressure of a discharge fluid compressed by a compression mechanism, and wear powder, produced from an annular seal (which receives the pressure of the discharge fluid) as a result of precession of the stationary scroll, is arrested, thereby achieving the scroll compressor high in efficiency and reliability. A pressure-receiving surface for receiving a back pressure of the discharge fluid so as to press the stationary scroll toward the movable scroll is formed on that portion of the stationary scroll disposed around a communication port which is formed in the stationary scroll, and communicates with a discharge port.

Abstract: A hermetic compressor according to the present invention uses a compressing mechanism which includes a rotary cylinder having a groove, and a piston slidable in the groove, so that the piston is rotated on a locus of a radius E about a position spaced apart at a distance E from the center of the rotary cylinder, thereby performing a compression stroke. In this compressing mechanism, the rotary cylinder is rotated and slid within the groove by rotation of the piston on the locus of the radius E about the position spaced apart at the distance E from the center of the rotary cylinder. Therefore, two spaces are defined in the groove by the piston and varied in volume by the sliding movement of the piston, whereby the compression and suction can be carried out.

Abstract: A thrust plate disposed between an orbiting scroll member and a bearing for receiving a force axially exerted thereon is provided with a protrusion formed on the same plane as the thrust plate and projected radially inward. The bearing has a thrust plate holder comprising a recess to which the protrusion of the thrust plate fits in, by which the thrust plate is prevented from rotating while being able to move smoothly in an axial direction. Abrasion caused by rotation of the thrust plate is thus prevented, as well as abrasion on outer circumferential parts of the thrust plate can be prevented as a result of the thrust plate is capable of slightly shifting for adjustment to follow up any precessional movement of a thrust load.
