Title: Scroll type oilless fluid machine
Inventor: OSHIMA HIRONOBU
IPC: F04C18/02
Filed: 1994-09-07
Abstract: PURPOSE: To improve the sealing property at the abutting surface between a fixed scroll and the end plate of an oscillating scroll, and to suppress a friction following the rotation of both scrolls at the minimum, so as to reduce a gas leakage, by providing a labyrinth seal at least at one side of the opposite sliding surfaces of the oscillating scroll and the fixed scroll. CONSTITUTION: At both sliding surfaces 33 and 34 of a fixed scroll 6 and an oscillating scroll 7, a labyrinth seal 35 along the full periphery is provided to the sliding surface 33 of the end plate 11 of the oscillating scroll 7. As a result, a gas pressure of a high pressure or a medium pressure flowing in from a back pressure chamber 39 into a compression chamber 14 generates a pressure loss by plural circular grooves to form the expansion chamber of the labyrinth seal 35, and the gas pressures at the engaging part of laps 10 and 12, and in the back pressure chamber 39 can be balanced. Consequently, the gas flowing in from the back pressure chamber 39 into the compression chamber 14 is reduced along the full peripheries of the scrolls 6 and 7, and the performance of a fluid machine can be improved.

Abstract: PURPOSE: To set recording media of different specifications by placing a recording medium at a predetermined tray when the recording medium is a single body, centering the recording medium according to the presence/absence of a hub, magnetically holding a magnetic body of a clamper or the hub by an annular magnet of a turntable. CONSTITUTION: When a recording medium is a single body, the medium is placed on a predetermined tray. As the tray is raised to a recording/reproducing position, a center hole 52a butts against a flange part 32a, so that the recording medium is automatically centered. Without a hub in the recording medium, a clamper 8 is lowered and a single body 52 of the recording medium is pressed/ held in touch with a supporting face 12d of a turntable by the magnetic attraction between a magnetic body 8a and an annular magnet 30. Meanwhile, a recording medium 51 stored in a cartridge and having a hub 55 is centered similarly at the turntable 12 and the hub 55 is magnetically held at the supporting face 12d by the annular magnet 30.  Accordingly, one recording/ reproducing apparatus is enough to handle recording media of different, specifications, coping with a multimedia system while saving cost and space.

Title: Electrophotographic toner
Inventor: NAKAYAMA KOJI
IPC: G03G9/087
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic toner which can be fixed at a low fixing temp. and has excellent fixing strength on a transfer paper without causing any problems relating to the storage property and offset property for practical use, by incorporating an acryl resin containing specified alkylacrylate and/or alkylmethacrylate [alkyl(meth)acrylate] as the structural component into the toner. SOLUTION: This toner contains an acryl resin containing at least an alkyl(meth)acrylate expressed by the formula as the structural component. In the formula, R is H or -CH3 and n is an integer 19 to 30. The alkyl(meth)acrylate is preferably used by >40 pts.wt. to 100 pts.wt. of the whole monomer components which constitute the resin. Thereby, the toner has enough fixing strength even when the temp. of a thermal fixing roll is low. When the toner is used for a copying machine or a printer, consumption of electric power can be decreased and reduction of the cost for the machine or fast copying rate can be realized due to decrease in the roll pressure.
