Title: Method for manufacturing reinforced piston
Inventor: TODA HIROYUKI
IPC: C22C1/00
Filed: 1989-08-18
Abstract: PURPOSE:To prevent the development of detachment, crack, etc., at interface between a formed body and a base material by constituting part needing mechanical improvement in a light alloy-made piston of the formed body formed with aluminum fine wire as reinforcing material and composite material consisting of matrix of aluminum or the alloy. CONSTITUTION:The part specially needing the improvement of high temp. strength, wear resistance, etc., in the light alloy-made piston, is formed with the ring-like formed body 1 of aluminum fine wire. Successively, this formed body 1 is set in a metallic mold 2 composed of outer mold 2a and lower mold 2b, and after pouring the molten light metal of aluminum or magnesium, etc., or the alloy thereof into the metallic mold 2, this is pressurized with a plunger 4 and solidified to produce the piston of reinforced composite material. Therefore, as the interface between the formed body 1 and base material is made to Al-Al or Al-Mg, stickness and suitability in the interface are good and further, as difference between both coefficients of thermal expansion is small, the development of detachment, crack, etc., can be eliminated.

Filed: 1988-08-26
Abstract: PURPOSE:To prevent the spreading of the foam polyurethane material to the surface of a floor carpet by sticking tapes partially only at the rear side of a backing layer responding to largely uneven parts of the floor. CONSTITUTION:A carpet material is prepared. The carpet material is a sheet- form material made by laminating a backing layer 3 to the rear side of a surface layer material 2 which is formed by a needle punching or a tufting. The backing layer 3 is composed by a heating device such as an infrared heater or the like, heating up to the softening and melting point of the thermal-plastic resin. Then, the carpet material is pressed with a formation pattern responding to the form of the floor, and cooled to fix the formation. Tapes 4 are stuck only to the parts of a large unevenness of the floor carpet 1. As the tape, a material not to spread the foam polyurethane is used. After that, the foam polyurethane layer is formed at the rear side of the backing layer 3 in a normal polyurethane pouring foam method. Consequently, the foam polyurethane never spreads to the front side of the carpet.

Title: Paper feeding device
Inventor: OOTSUKI KAZUTOSHI
IPC: G03G15/00
Filed: 1994-09-07
Abstract: PURPOSE: To improve the reliability of the separation action for the paper sheets and prevent the generation of a nonsent-out state, by the simple structure in which a paper sheet pressing is formed integrally on the rotary shaft of a paper feeding roller. CONSTITUTION: A paper pressing 12 is formed integrally on the rotary shaft 9 of a paper feeding roller 8. When a small-sized paper sheet 3 is used, each loop which is formed on both the sides of the paper sheet 3 is pressed by the paper feeding roller 8 which is close to a separating hook 4, during the separation operation. As the size of the used paper sheet 4 increases more, the distance between the paper feeding roller 8 and the separating hook 4 increases more, and each loop formed on both the sides of the paper sheet 3 increases, and the increased state of the loop is restricted by the paper sheet pressing 12. Accordingly, independently of the size, the stiffness of the paper sheet 3 is kept within a proper range, and the separation action for the paper sheet 3 is accelerated.  Further, each loop formed on both the sides of the paper sheet 3 is pushed out in the paper feeding direction by the revolution operation of the paper sheet pressing 12, and the generation of a nonsent-out state is prevented.

Abstract: PROBLEM TO BE SOLVED: To effectively utilize quantity of heat flowing out of a fluidized bed incinera tor in a drying process by a method wherein hot sands being fluidizing medium of a fluidized bed incinerator, as a heat source, flow into a fluidized bed drier and exhaust gas of the fluidized bed incinerator, as a fluidizing gas, flows into the fluidized bed drier. SOLUTION: Combustion gas flows upwards through a riser 12 and exhaust gas flows from an upper end of the riser into a hot cyclone 14 together with fly ashes and hot sands being a fluiding medium 9. The cyclone 14 separates the hot sands in the combustion gas and the separated hot sands are recovered from a separated solid discharge port 26 as heat sources for a drying chamber 4 of a fluidized bed drier 2. On the other hand, after the ashes are removed, the exhaust gas flowing through an exhaust gas discharge line 15 flows through a waste heat boiler 17, as a heat source fluid, and then flows into a heat exchanger 18 and into an exhaust gas processing device 19 comprising an ash cyclone for collecting ash, a dust collector etc., and is discharged to the outside from a stack 16 by means of a fan device 20.  And a part of the exhaust gas is passed through an exhaust gas circulation line 22 and a drier fluidizing gas feed line 21 of the drier 2 so as to flow into the drying chamber 4 as a fluidizing gas.
