Abstract: A fuel pump apparatus is made free from the influence of height fluctuations of the surface of fuel in a fuel tank by providing a fuel inlet window in the side wall of a float chamber for containing a fuel gauge, which is provided inside the side wall of a housing. The fuel inlet window provides communication between the float chamber and the fuel storage chamber in the fuel tank. Even when there are height fluctuations of the surface of fuel in the fuel tank due to vibrations or turning during running of the automobile, the height fluctuations of the fuel surface are damped in the float chamber because the fuel inlet window acts as a buffer to prevent direct influence of the height fluctuations of the fuel surface.

Abstract: An optical recording medium having at least one aluminum nitride and silicon nitride composite dielectric layer is provided. The amount of aluminum nitride in the dielectric layer, x, is more than zero and less than or equal to about 95 mol %. The amount of silicon nitride in the layer is represented as (100-x) and is equal to or greater than about 5 and less than 100 mol %. The refractive index of the composite dielectric layer is between about 1.70 and 2.15. The composite dielectric layer is sandwiched between a transparent support such as a plastic transparent support and an optical recording layer adapted to be irradiated by laser light in order to read, write or erase information in order to protect the recording layer.

Abstract: Sheets of laminated paper are stacked and made into air-tight flat bags with air inlets. After air is supplied into the bags, the air inlets are air-tightly closed to form shock absorbers 50 encapsulating the air. The laminated paper is made by stacking on a paper base a water-soluble polyvinyl alcoholic layer, having a saponification of 80 to 90 mol % and a degree of polymerization of 500 to 2500, to a total thickness of 90 .mu.m or less and a gas permeability of 800 thousand seconds per 100 ml or more. The air is introduced into flat bags 51 to 50 to 80% of maximum inflation to ensure their shock absorbing function. A package 100 is made by putting an appropriate number of discrete shock absorbers 50, or a continuous series of shock absorbers 50, in gaps between a casing 10 and the package content 70. The shock absorbers 50 need not be spread all over the entire surface of the package, so long as they are sufficient to provide the needed contact area to ensure a maximum static load of 0.07 kgf/cm.sup.

Abstract: Equipment which automatically manufactures cushioning material by filling air inside polyvinyl alcohol laminated paper and sealing the filled material into individual bags. The manufacturing equipment 1 is provided with a material roll 20 on which a sheet material of polyvinyl alcohol laminated paper is wound. The sheet material 10 is rolled out by a feeding roller 40 from the material roll 20, and the sheet material 10 in a known length, adjusted by a length adjusting device 50 having a roller 42 which goes up and down, is supplied intermittently to a bag forming device 100 located downstream thereof. The bag forming device 100 is provided with a pipe member 105 and a sailor 110, which is a guide plate to reverse the sheet material 10 and form it into a tubular shape, and the sheet material 10 is fed along the pipe member 105 after being formed into a tubular shape. Feed rollers 130 and auxiliary belt 120 are arranged at the periphery of the pipe member 105.

Abstract: A magnetic thin film recording layer comprised primarily of a light rare earth element and a transition metal element is disclosed. Other elements are optionally included in the film. The film has an easy axis of magnetization perpendicular with respect to the surface of the film. Magneto-optic recording systems using such films are also disclosed.

Abstract: A magneto-optic recording medium including a transparent substrate and a non-oxide dielectric layer formed thereon is provided. The dielectric layer includes a first dielectric material of the type which exhibits cracks running in a generally radial direction when deposited on a surface and which is designated dielectric Group A and a second dielectric material which exhibits cracks running in a generally tangential direction when deposited on a surface and which is designated dielectric Group B. The dielectric layer may be separate layers or a mixture of the two dielectric materials.

Abstract: An optical recording medium having two adhered substrates one of which has a magneto-optic recording layer thereon and the other of which has at least one dielectric layer thereon so as to improve stability and weatherability. The dielectric layer is a transparent oxide, a nitride or a mixture of an oxide and a nitride and has a thickness between about 30.ANG. and 10 .mu.m. In an especially preferred embodiment, neither substrate is provided with any layers in either the internal area or the circumferential area of a disk and the substrates themselves are exposed and adhered together with adhesive.

Abstract: A magnetic head for perpendicular magnetization recording especially suitable for operation from only one side of a magnetic tape includes a central magnetic pole surrounded in spaced relationship by a peripheral magnetic pole. An exciting coil is wound around the central magnetic pole for maintaining the central and peripheral magnetic pole at different magnetic potentials. Both magnetic poles are located on the same side of a multi-layer magnetic recording medium to be magnetized by the recording head.

Abstract: The invention provides a novel method for imparting water-repellency to a woven fabric such as velveteen by use of a silicone-based water-repellent agent. In addition to water-repellency, the fabric treated by the inventive method has many excellent characteristics required in a fancy fabric as well as susceptibility to bonding with a lining cloth by use of a hot-melt adhesive. The water-repellent agent used in the method comprises, in addition to an organohydrogenpolysiloxane, either one or a combination of a linear organopolysiloxane, in which at least 5% by moles of the organic groups are alkenyl, e.g. vinyl, groups, and a resinous organopolysiloxane composed of the monofunctional organosiloxane units and tetrafunctional siloxane units SiO.sub.2 in a limited molar proportion.
