IPC: B32B3/26
Filed: 1990-10-18
Abstract: PURPOSE:To enable to inject a liquid at higher speed by coating a release sheet having a shape corresponding to a partition chamber and a flow path with a foaming agent and holding the release sheet between sheet materials to be flexible sheets and sticking both sheets. CONSTITUTION:A film composed of a polyester resin such as polyethylene terephthalate is used preferably as a release sheet. Various foaming agents such as a decomposable foaming agent consisting of inorganic and organic compounds generating a gas by decomposition through heating such as sodium bicarbonate, diazoaminobenzene, etc., a volatile foaming agent made up of a volatile liquid such as hexane, etc., can be utilized as a foaming agent, but ammonium carbonate is preferable from the points of a decomposition temperature and the quantity of the gas generated from it. The release sheet 4 coated with the foaming agent is held between two sheet materials 1a, 1a, and press- vulcanized by using a flat press mold, thus mutually laminating the sheet materials 1a, 1a. Accordingly, the foaming agent coated is foamed and a partition chamber and a flow path formed between two stuck sheet materials are expanded previously, thus facilitating liquid injection work to the partition chamber and the flow path.

Filed: 1987-11-05
Abstract: PURPOSE:To make reduction in starting torque possible by composing fluid of magnetic fluid, and forming either of a supported surface and a supporting surface on a fixed side with a magnetic part to attractedly hold the magnetic fluid. CONSTITUTION:A rotary shaft 9 rotating highspeedly at a fixed number of revolutions generates dynamic pressure within magnetic fluid 42 existing in a bearing gap in an upper and a lower radial bearing 20, 21, and the shaft 9 is therefore rotatingly driven with supporting surfaces 38, 38b on each fixed side mutually kept at about concentric state, and is simultaneously rotatingly driven in a thrust bearing part 22 also as the shaft 9 is kept by the dynamic pressure of the magnetic fluid 42 existing in each bearing gap at an axial position where the total weight of a rotary body balances with the sum of upper dynamic pressure. Even when rotation has been stopped, the magnetic fluid 42 attractedly held on each of magnetic parts 39, 40 is locally existingly kept in each bearing gap. Thus even during a build up period until the dynamic pressure occurs at the time of starting an engine, low frictional driving can be performed without fixed contact caused on a bearing surface to reduce starting torque.

Abstract: PURPOSE:To prevent copying paper sheets from being damaged while they are prevented from abutting abut against a stopper plate which is formed at the rear edge of a loading plate, by enabling the stopper plate to be rotated rearward from its upstanding posture when copying paper sheets are supplied into a paper feed cassette. CONSTITUTION:When a cover 3 is rotated forward about pivot pins 5, 15' as fulcrums to be opened to supply new copying paper sheets in a paper feed cassette 1, the front end 16 of the cover 3 presses the forward section of a loading plate 7 overcoming the urging foces of bent plate splings 6, 6'. Then the rear end edge of the loading plate moves upward until it abuts against a stopper pin 13.
