摘要： A discarded industrial product recycling system capable of acquiring pertinent data required for processings of discarded industrial products such as discarders, reception dates, persons responsible for disposal, disposal dates and so forth for selecting proper disposal for each of the discarded industrial products while automatizing the article data acquisition to a possible maximum for enhancing the enhance disposal rate. An electronic tag (radio-frequency identifier tag) is attached to each of discarded industrial products to allow data required for the processing to be written and read by readers/writers. At a time point and a place where a discarded industrial product is received, basic data required for the processing of that article is written in the electronic tag. Pertinent processing route for each of the manufactured articles is decided by reading the data from the electronic tag while writing additional data in the tag as occasion requires. Properties of plastic material are measured, results of which are written in the electronic tag. Classification of component parts resulting from disassembling is carried out by affixing an electronic tag to each palette, reading the data from the electronic tag attached to the discarded industrial product and writing a code of assortment destination for the parts carried by the palette in the electronic tag affixed thereto on the basis of the data read from the electronic tag attached to the discarded industrial product.

摘要： In a gas pressure increasing system for increasing the pressure of a refrigerant gas or air having a scroll compressor, a condenser, a pressure reducing means and an evaporator or a scroll compressor and a gas cooler, an exhaust gas released from the scroll compressor after having its pressure increased by the scroll compressor itself is cooled and expanded to reduce its pressure to an intermediate pressure level to produce a gas of an intermediate pressure having a cooling capability. The gas of the intermediate pressure is used to provide a force for axially sealing an orbiting scroll member of the scroll compressor as well as to cool the scroll compressor and a motor.

摘要： [Problem] To provide a scroll compressor that can be easily mass-produced as a compact and lightweight structure at a low cost, and in which efficient low-capacity control is possible in a super-low speed operation mode. [Means for Resolution] In the compressor, a discharge guide pipe 120 that guides a refrigerant gas in a discharge head space 123 within a discharge head cover 118, which is disposed on a top plate of a fixed scroll 102 equipped with a release mechanism on an outer circumference of a discharge port 108, from the space 123 to the outside of a sealed case 115, and a suction pipe 113 for sucking in the refrigerant gas are coupled to each other and communicated with each other by a solenoid valve 122 whose opening and closing are controlled in accordance with a pulse-width modulation control signal, and a bypass passage that guides the refrigerant gas within the space 123 from the guide pipe 120 to the suction pipe 113 is formed. When low-capacity control is required in a low-speed rotation range, a motor 100 is driven by an inverter 128 and an operation is performed in which the ratio between the operation for closing the valve 122 and the operation for opening the valve 122 in accordance with the pulse-width modulation control signal from a solenoid drive circuit 129 has been altered.

摘要： A scroll compressor includes: a fixed scroll 112; an orbiting scroll 109; a crankshaft 103 having an eccentric section 108 at an end portion; an oil supply hole 115 penetrating an inside of the crankshaft in an axial direction and having an opening portion on an end surface of the eccentric section: an orbiting sliding bearing 110 provided at the orbiting scroll and sliding by engaging with the eccentric section; and an oil supply passage 116 provided at an outer circumference of the eccentric section. The scroll compressor is structured so as to lubricate a gap between the eccentric section and the orbiting sliding bearing by lubricating oil supplied through the oil supply hole. At the outer circumference of the eccentric section, an axial loss reduction groove 117 is provided separately from the oil supply passage, and seal sections 118a, 118b are provided on at least one of the end surface side and a base end side of the eccentric section of the loss reduction groove. With this configuration, shear resistance of an oil film by the lubricating oil, which exists between an outer circumferential surface of the eccentric section of the crankshaft and an inner circumferential surface of the orbiting sliding bearing, can be reduced, and a bearing loss during fluid lubrication can be reduced.

摘要： PROBLEM TO BE SOLVED: To reduce a loss due to a back-pressure adjustment to adjust an attracting force between a stationary scroll and a rotating one.
SOLUTION: A scroll compressor is provided with: a back-pressure chamber 18 which is provided on the back side of the rotating scroll 8 rotatably provided opposite the stationary scroll 7 and which an intermediate pressure between a discharge pressure and a suction pressure is introduced into; a back-pressure adjustment valve 2 which releases fluid in the back-pressure chamber into a suction chamber or a compression chamber in an initial stage of compression through a communication passage 2f formed at an addendum of the outermost circumference lap 7e of the stationary scroll, according to a difference between a suction pressure introduced through the communication passage 2f or a compression initial pressure and a pressure in the back-pressure chamber. The rotating scroll 8 is provided with a through hole 1 which communicates a compression chamber 13 uncommunicated with the communication passage 2f, with the back-pressure chamber 18, and the compression loss due to reexpansion is reduced by releasing part of an excessive pressure of the back-pressure chamber 18 into the compression chamber 13.

摘要： PROBLEM TO BE SOLVED: To make it possible to ensure smooth lubrication of end plate surfaces in a scroll compressor through adoption of a simple structure and to prevent the cut-off or baking on end plate surfaces by lowering sliding surface pressure.
SOLUTION: The scroll compressor 1 is equipped with a fixed scroll 100 made of a spiral-shaped lap 102 erected on a board 101; with a revolving scroll 200 made of a spiral shaped lap 202 erected on a board 201, and arranged to revolve in engagement with the fixed scroll 100 so as to form a compression chamber 130; and with an external circumference space 411 in which a pressure lower than the discharge pressure prevails, and to which oil is supplied outside the revolving scroll 200. The fixed scroll 100 has, on the external circumference side of the compression chamber 130, a end plate surface 105 to which the board 201 for the revolving scroll 200 touches. Further on the end plate surface, a closed oil supply groove 106 is formed with one of the ends linked to the external space 411 and another end extending to the circumference direction.
