In a sealed-type scroll compressor having a stationary scroll member and an orbiting scroll member, the stationary scroll member is fixed after rotating it in an orbiting direction of the orbiting scroll member by a predetermined angle from a phase angle position where a possible orbiting radius between both scroll members is made maximum at the temperature before driving the scroll compressor.

When sliding elements, slide bushings, vanes and Oldham rings employed in various types of refrigeration compressors and other applications meet the following conditions, they resist sticking to aluminum-base components, resist depletion of the oil film on slide faces, and exhibit excellent wear resistance. Firstly, the elements must comprise an iron-base sinter having closed cells on at least the slide face. Secondly, in order for the oil film to be maintained on the slide face by the closed cells and to enhance lubricating properties, the proportion of closed cells having circular-equivalent diameter of 10 &mgr;m or less, i.e. the number of ≦10 &mgr;m cells/total number of cells, must equal 85% or more, and the opening area of the closed cells on the slide face must equal 5% or less. Finally, the sliding element density must be 7.3 g/cm3 or higher.

An orbiting scroll is engaged to and moved orbitally in relation to a fixed scroll at variable speeds. An offset surface is provided in at least one of the wraps of the fixed scroll and/or the orbiting scroll, by which a space S is created in one of the compression chambers formed between the fixed scroll and the orbiting scroll, which is thereby unsealed and opened to the inlet port side. The offset surface has a length from a position in the spiral length which satisfies the required compression ratio of one of the compression chambers in a low speed operation to the end of the spiral. An injection port is positioned such as to open to an unsealed area of this compression chamber, and gas injection shutoff and resumption is controlled through this injection port as appropriate to the situation.

The present invention provides a rotary sinker capable of suppressing energy loss and achieving reduction in the driving load, a knitting machine provided with the rotary sinker, and a knitting machine control apparatus. The sinker 3 comprises a rotating body 4 that can rotate about an axis, and supporting members 32, 34 which rotatably support the rotating body 4. A circumference edge portion of the rotating body 4 is provided with sinker teeth 41 formed of a plurality of projecting sections to which rotational drive force is transmitted and with which a knitting yarn can be engaged.

The knitting element has a rotor capable of rotating about an axis and makes a stitch by using rotational motion of the rotor. The knitting element has a rotor having a rotating shaft which protrudes in the direction of the axis and a bearing which slidably supports the circumferential face of the rotating shaft. An engagement recess capable of engaging knitting yarn is formed in the circumferential face of the rotor.

A reinforcing plate is overlaid with a decoration sheet with a first adhesive layer interposed, and heated and pressed to form first laminate. A surface of the decoration sheet in the first laminate is coated with a clear second adhesive layer of a liquid polyurethane resin, a surface of which in turn is overlaid with a clear film and heated and pressed to prepare a second laminate. The second laminate is placed within a mold and a resin is insert molded on the reinforcing plate in the second laminate. A clear hard coating is preferably formed on a surface of the second laminate in order to provide higher abrasion resistance.

The knitting element has a rotor capable of rotating about an axis and makes a knit stitch by using rotational motion of the rotor. The rotor is formed in a circular disk shape. A pair of bearing plates is separated from each other in a radial direction of the rotor. The rotor is supported rotatably by bearing plates support slidably the circumferential surface of the rotor. A plurality of teeth to which rotational drive force is transmitted is formed in a circumference edge portion of the rotor. An engagement recess capable of engaging knitting yarn is formed in the circumferential face of the rotor.
