IPC: B32B5/18
Filed: 1993-12-29
Abstract: PURPOSE:To obtain a floor material having excellent cushioning properties by forming a plurality of slits having a specified shape from both end faces of a resin foam block having closed cells. CONSTITUTION:Specified slits 2 are formed to a resin foam block 1 acquired by foaming a raw resin consisting of thermoplastic or thermo-setting foams at a proper expansion ratio. The slits 2 are formed so as to make approximately right angles in the direction that a shock is applied from end faces in approximately parallel with the direction that the shock is applied when the block material is used. The slits 2 are formed while crossing the central section of the resin block 1 in the other end face 3b direction from one end face 3a. The length D1 and D2 of the slits 2 is made longer than the half of the width L of the resin foam 1, and the slits from both end faces are overlapped near centers. The slits having such length are formed, thus instantaneously absorbing the shock applied to the cushioning material, then displaying excellent sound- insulating properties.

Title: Gravitationally flowing-down type polymer tank
Inventor: MATSUNAGA TATSUAKI
IPC: B65D47/22
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To dispense with a pump and prevent hands from getting dirty and completely and uselessly discharge kerosene in a polymer tank without the rest, when kerosene is supplied in a cartridge tank of a kerosene stove. SOLUTION: A rubber ball as a cock is put in an integrally molded polymer tank. At first, a hose of the polymer tank is put in the pouring opening of a cartridge tank for a stove. Then the rubber ball (full line) retained at a protrusion in the hose is picked up from the outside to transfer it from the part 1 of the hose to a protrusion at the second stage so as to be kept therein (chain line). When kerosene begins to flow out and the cartridge tank has been filled with kerosene, the rubber ball is returned to the original position (full line) by picking up the part 2 of the hose to stop the outflow of kerosene. In this way, a polymer tank charged with kerosene is put on an exclusive base or the like and kerosene is discharged from the hose attached to the lowermost part of the polymer tank by means of the natural law and hence, any pump is not required.

Title: Manufacturing apparatus for semiconductor device
Inventor: AMAGASAKI YOSHIHIRO
IPC: H01L21/3065
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device with a good economical yield, reliability, and high productivity in a usual wafer treatment technique, by forming a removable thin film on an inner wall of a wafer treatment chamber and sticking a reactive product on the thin film. SOLUTION: A thin film 8 made of carbon- or silicon-based polymer is stuck with an adhesive on an inner wall of a chamber 1 and a surface of a focus ring 6 in a way that the thin film 8 is removable from these faces, because a gas that tends to generate a carbon-based polymer flows and gets in contact with the inner wall or the surface of the focus ring 6. When etching steps are repeated and a given amount of carbon-based polymer is deposited on the thin film 8 on the inner wall of the chamber 1 or the surface of the focus ring 6, the thin film 8 is removed before dusts flaking from the carbon-based polymer is generated. In this way, maintenance related with the sticking of the carbon- based polymer can be eliminated and a yield in product can be improved.
