Abstract: According to one embodiment, a nonvolatile semiconductor memory includes a first electrode and a second electrode spaced from the first electrode. A memory element and a switching element are disposed between the first electrode and the second electrode. The switching element includes a tunnel insulating film enabling carrier tunneling, and the tunnel insulating film includes yttrium and oxygen and at least one of tantalum, titanium, and zirconium Ti, and Zr.

Abstract: According to one embodiment, memory device includes a first, second, and third conductive layers in this order, a resistance change layer between the first and the second conductive layers, and a switching layer between the second and the third conductive layers. The switching layer contains: at least one first substance from a group consisting of oxide of at least one element from a group consisting of Cr, La, Ce, Y, Sc, Zr, and Hf, nitride of the at least one element, and oxynitride of the at least one element; a second substance being at least one metal from a group consisting of Te, Se, Sb, Bi, Ge, and Sn; and at least one third substance from a group consisting of oxide of the second substance, nitride of the second substance, and oxynitride of the second substance.

Abstract: The invention provides an air bag apparatus which is simple in structure and light in weight while assuring a sufficient strength and wherein a pad cover can be mounted readily onto a base plate by a simplified mounting apparatus. The air bag apparatus has at least an air bag for protecting a driver of a vehicle upon collision of the vehicle, a base plate for mounting thereon a gas generator for inflating the air bag, and a pad cover secured to the base plate for accommodating the air bag and the gas inflator therein. A portion of the base plate is deformed into a predetermined shape to secure the pad cover to the base plate. Preferably, a portion of the base plate is bent to form a side inner face portion and is further folded back to form a side outer face portion, and a terminal portion of the pad cover is held between and secured by the side outer face portion and the side inner face portion of the base plate.

Abstract: An air bag includes a pair of laminated films and an opening for inflator, in which each laminated film is at least one elastomer layer and at least one shape holding layer.

Abstract: An air bag comprises a facing sheet and a backing sheet of thermoplastic resin film and laminated on at least an outer peripheral joining region thereof with a thermoplastic resin film. An adhesion reinforcing layer(s) is interposed between the facing sheet and the backing sheet at the joining region and made from a thermoplastic resin provided that an insulating layer is interposed in the adhesion reinforcing layer at a region ranging from a position corresponding to an approximately center of the outer peripheral joining region toward the inside thereof. The facing and backing sheets and the adhesion reinforcing layer are heat-welded together at the outer peripheral joining region.

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.
