Abstract:
A first air bag comprises an upper cloth and a lower cloth, the peripheries of the both cloths being connected, characterized in that the upper cloth consists of an airtight sheet obtained by weaving a composite fiber composed of a filament core and a thermoplastic polymer bonded thereto which has a melting point lower than that of said filament core, and then fusing said thermoplastic polymer so that the surface of said upper cloth has a continuous thermoplastic polymer layer. A second air bag consists of a membranous material having a breaking extension of 100% or more. A third air bag comprises an elastomer body and a shape-retaining member partially attached to the elastomer body, said member being composed of elastic fibers or threads and high-modulus fibers.
Abstract:
A porous ceramic structure suitable for use as a filter for molten metal, in which a porous ceramic body having pores capable of passing a fluid therethrough is covered with a metal layer over the wall surface of the pores such that a fluid may flow through the pores while in contact with the metal layer. The filtering efficiency can be improved due to the increased wettability between the ceramic filter and the molten metal.

A backside covering member (1) for a solar battery is made by integrally laminating an outer film (3) and a moistureproof film (2) with EVA adhesives (4). The moistureproof film (2) is constituted of a base film and a coating layer of an inorganic oxide deposited on a surface of said base film. A backside covering and sealing film is made by integrally laminating the aforementioned backside covering member (1) and an EVA film (6) together. A solar battery (10) is made by sealing solar cells (7) between a front side transparent protective member (8) and the aforementioned backside covering member (1) as a back side protective member. The present invention provides a backside covering member for solar battery and a backside covering and sealing film which are light and thin, are excellent in moistureproof property and durability, further have good insulation performance, and do not cause leakage of current and a durable, high-performance solar battery using the aforementioned backside covering member as a back side protective member.
Abstract:
A sealing film for sealing a solar cell is provided which can effectively prevent solar cells from being damaged, prevent inferior deaeration, and prevent resin of the layers from flashing during a sealing integration process of manufacturing a solar battery. The sealing film is composed of a film formed of ethylene-vinyl acetate copolymer resin. The film is processed by an embossing treatment to have concavities. A percentage defined by VH / VA x 100% is in a range from 5% to 80%, wherein VH is the total volume of the concavities per unit area of the film and VA is the apparent volume of the film which is the product of the maximum thickness of the film and unit area. A solar battery is manufactured by laminating a front-side transparent protective member 11, A sealing film for sealing a solar cell 13A, the solar cells 14, another layer for sealing solar cells 13B, and a back-side transparent protective member 12 to make a laminated body, and pressurizing and heating the laminated body to be integrated.
Abstract:
A sealing composition including ethylene-vinyl acetate copolymer (EVA), a cross-linking agent, and either a polymerization inhibitor or chain transfer agent. A method of sealing a device between two substrates through the following steps of; forming a layered structure by interposing the device sandwiched with two sheets or films made of the sealing composition in between two substrates to make a layered structure; deaerating the layered structure by heating under reduced pressure; unit the layered structure by curing (cross-linking) ethylene-vinyl acetate copolymer. By controlling an initial curing rate of the EVA sealing composition, sealing can be carried out with good productivity and high yield without problems of left bubbles and poor adhesion.
Abstract:
A film-reinforced glass, characterized in that it comprises a sheet of flat glass, an organic resin membrane comprising EVA as a main component laminated on the glass and, laminated on the membrane, a film comprising an organic polymer, these laminated materials being crimped with each other. The organic resin membrane may have electrical conductivity, and a hard coat layer may be formed on the film. The film-reinforced glass can be used for producing a thin glass which is excellent in impact resistance and the resistance to being cut through.

A solar cell cover material/sealing film formed by laminating for integration the cover film and an EVA film. A solar cell formed by sealing solar cell elements between the cover material and a rear-surface-side protection member. A transparent film combining a moisture-proof feature with a light-fast feature can reduce the weight of the solar cell and improve its shock-resistance and durability.
Abstract:
A covering member is used as a transparent protective member for protecting solar cells of a solar battery. The covering member includes a transparent high-sunproof film, a transparent high-moistureproof film laminated on the transparent high-sunproof film, and ethylene-vinyl acetate copolymer adhesive disposed between the transparent high-sunproof film and the transparent high-moistureproof film. The high-moistureproof film is formed of two transparent polyethylene terephthalate films and inorganic oxide coatings coated on the respective films. The inorganic oxide coatings are formed of silica and/or alumina, and coating surfaces thereof are bonded to each other. The ethylene-vinyl acetate copolymer adhesive contains ultraviolet absorbing agent and organic peroxide as a cross-linking agent.
Abstract:
An air bag assembly has a base plate (108) and a rupturable pad cover (107) housing the air bag (114). The edge of the pad cover (107) is secured around the edge of the base plate (108) by bending in caulking portions (106) of the base plate periphery to trap edge projections of the pad cover. To assemble the air bag components, the base plate (108) is positioned on a support table (104) of an assembling apparatus having an upper press portion (101). The workpiece constituted by the air bag assembly components is surrounded by a cam slide apparatus (102) having press blocks (103) which, by means of sliding cam faces (103A, 105A) convert the downward force of the press portion (101) to an inward force on caulking blocks (105) surrounding the workpiece. The caulking blocks (105) act to bend the caulking portions (106) of the base plate into the securing position to hold the airbag assembly together.
