Title: Preparation of cellulose membrane
Inventor: KANZAWA CHIYOJI
IPC: B01D71/10
Filed: 1984-03-07
Abstract: PURPOSE:To increase mechanical strength and to reduce the change of flux of stream in the permeation direction by using an organic solvent which dissolves cellulose but dissolves in the solvent of the cellulose soln., as a component for a coagulating liquid. CONSTITUTION:Cellulose soln. is prepd. using a conventional kind of solvent for cellulose. Any org. material which does not dissolve cellulose but is soluble in the solvent for cellulose may be useful for the solvent in the coagulating liquid. Combination of the cellulose solvent and the coagulation liquid solvent may be eventually restricted, but the problem may be eliminated by the adoption of immersing and stirring or by the use of mixed solvent. A cellulose film is prepd. by immersing a substrate impregnated or coated with cellulose soln. in a coagulating liquid comprising an org. solvent, or the cellulose soln. is casted directly in the org. coagulating liquid without using a substrate.

Title: Scroll turbo machine
Inventor: IWATA TORU
IPC: F04D23/00
Filed: 1990-02-23
Abstract: PURPOSE:To improve pressure characteristics and efficiency by providing a fluid blowing means for blowing off high pressure fluid in the direction so as to promote scroll formation of the fluid flowing into a main passage from an inlet port. CONSTITUTION:In a housing 2 which forms a main passage 24, a blow-off passage 8 as a a fluid blowing means is formed. This blow-off passage 8 is formed by an introduction part 81, a guide part 82 and a blow-off part 83. A part of high pressure fluid in the main passage 24 is introduced to the neighborhood of an inlet port 61 by the blow off passage 8. The fluid flowing into the main passage 24 from the inlet port 61 directly flows into a blade and blows off in the direction to promote formation of a scroll. Thus, the scroll is formed in the main passage 24 without disturbing flow of the fluid near the inlet port 61. Therefore, pressure characteristics and efficiency can be improved.

Abstract: PURPOSE:To stabilize the switching operation and to improve the reliability by providing a semiconductor switching element, an input circuit to give a control signal to the switching element, and a feedback circuit to give a positive feedback to its control input side, between a pair of electrode terminals. CONSTITUTION:To a semiconductor switching element 4 (shown as FET hereafter) to enforce and weaken the solenoid 3 of an electromagnetic valve, a positive feedback circuit 7 is added.

Title: Sheet feed tray control device for copying machine
Inventor: KANETANI KOICHI
IPC: G03G15/00
Filed: 1987-02-28
Abstract: PURPOSE:To prevent the occurrence of choking with a transfer sheet and break of the sheet in a tray, by a method wherein, when the tray is set, a pickup roller is escaped upward. CONSTITUTION:When a sheet is present during setting of a tray, a rising signal is fed to a motor 2 by which a tray table 1 is driven. When the motor 2 is stopped, a transfer sheet is positioned in a sheet feed height. When a tray lower ing switch is depressed or sheets in the tray run out during the feed of the sheets, the motor 2 for a tray table outputs a lowering signal. When a shield plate is detected by a lower limit sensor 14, the motor 2 is stopped. When the sheets do not run out and the shield plate is off an upper limit sensor 13, a rising signal is immediately outputted to the motor 2, and a sheet feed posi tion, being lowered due to a decrease of transfer sheets, is restored to an origi nal position. Even if, when a tray is set during the feed of the transfer sheet, quantities of the transfer sheets are loaded or the transfer sheet is curled to some extent, a pickup roller 9 is escaped upward, and thereby there is no fear of the end part of the sheet making contact with the pickup roller, and reliabil ity is improved.

Abstract: PURPOSE:To easily and economically manufacture a ball bush of least resistance and partial wear by forming the bush so that balls are rotatably fitted into diagonal holes formed in a retainer and the outer surfaces of the balls contact the inner surface of the bush body and the outer surface of a round shaft. CONSTITUTION:A round shaft 11 is inserted for its outer surface to contact each balls 4. A bush body 1 is then inserted and fixed into the inside of a specific, for example, plastic product 12 or metal product. When the plastic product 12 is fixed and the round shaft 11 is moved linearly in the direction of the arrow, each ball 4 tends to move in the direction of movement of the round shaft 11 while it rotates in the direction of the arrow, but the movement of the balls is blocked by a retainer 2, and each ball pushes diagonal holes 3. When the diagonal holes 3 are pressed by the balls 4, the retainer 2 rotates by components of the pressing forces. When the round shaft 11 is moved in opposite direction, each ball and the retainer 2 rotate reversely.
