PURPOSE:To increase life without decreasing battery performance by covering the surface of a plate with a solid layer comprising acid resistant and electrochemically inactive oxide powder, water absorbable high polymer fibers, and a binder. CONSTITUTION:2-5g of polyacrylonitrile fibers having a length of 10mm. are mixed to a mixed solution of acid resistant and electrochemically inactive powder su...

PURPOSE:To prevent coming off of active material and increase life by forming a porous rigid layer comprising electrochemically inactive, and acid resistant inorganic powder and an acid resistant inorganic binder on the surface of a plate. CONSTITUTION:SiO2, water, and monobasic aluminum phosphate which is an acid resistance inorganic binder are mixed to form slurry. A positive plate is made by fi...

PURPOSE:To increase life without sacrifice of battery performance by coating the surface of a plate with a mixture comprising electrochemically inactive oxide powder, water, and a binder, and making them foam and drying to solidify. CONSTITUTION:Metallic aluminum powder is added to a mixed solution of alumina powder, water, and monobasic aluminum phosphate which is a binder to form a mixed paste. ...

PURPOSE:To prevent swelling of a plate and coming off of an active material by filling and covering between a positive plate and a negative plate and circumference of a plate group by a porous rigid layer comprising electrochemically inactive inorganic powder and an acid resistant inorganic binder. CONSTITUTION:Al2O3, water, and monobasic aluminum phosphate which is an inorganic binder are mixed t...

Raw materials are reclaimed from magnetic tape scrap by cutting the scrap into small pieces; treating the cut scrap with aqueous alkali solution; stirring the alkali-treated scrap at high speed thereby completely separating them into tape substrate and magnetic powder; washing the scrap with water and draining it; stirring only the tape substrate fragments at high speed under vacuum and at a tempe...

PURPOSE:To end and stop work precisely by calculating the proposed number of times of reciprocation on an automatically formed travelling course, and when a service car travels more than a prescribed distance under non-detecting status after passing the calculated number of times, stopping the service car forcibly. CONSTITUTION:An unmanned traveling service car V such as a lawn mower is provided w...

A heel holder of a ski binding for assuming an open position from a closed position when a ski boot is released from a toe holder of the binding, the heelholder including a baseplate, a housing mounted on the baseplate, a soleholder pivotally mounted on the housing for rotation between open and closed positions, a retaining member mounted on the soleholder for releasably retaining the soleholder i...

Generally, the present invention relates to a resin-treated filter fabric which comprises a surface or batt layer comprised of glass fibers which is joined, by needling, to an underlayer which is comprised of mineral fibers. The present invention includes within its scope a method of manufacturing such a filter fabric.

A process for the detoxication of waste slurries, in particular from the leather and skin industry, containing heavy metal salt complexes and organic materials comprises treating a suspension containing at most 100 kg/m<3> of solid material with sulphuric acid and/or a mineral acid mixture composed of at least 30% by weight of sulphuric acid. The acid liquid containing the heavy metal salts is sep...

A pickup system for an optical disc reading/recording apparatus in which a micro Fresnel lens, formed with concentric circular gratings, is used in place of an optical element, such as an objective lens, for focussing and collimating light beams from a semiconductor light source. The pickup system so formed is light in weight, easily miniaturized, and inexpensive to manufacture. The micro Fresnel ...

PURPOSE:To obtain a homogeneous dielectric film that is high in dielectric constant and dielectric strength and can be spread widely, by forming an uncrosslinked polyvinylidene fluoride type resin having a specified inherent viscosity value by a solution process into a film having a specified degree of surface orientation and a specified thickness. CONSTITUTION:To a copolymer (A) of 95mol% or more...

A tile or other building product is manufactured by firing a green product from a coarse component such as metallurgical slag or crushed rock and a fine component such as fly ash, with sodium silicate or other alkali metal compound which reacts with at least the fine component to form a binding matrix.

The adherence of polyolefins to polar polymers and/or metals is improved by mixing the polyolefin melt with polymers (I) which improve adherence and opt. a small amt. of an organic peroxide to partly graft (I) on the polyolefin. (I) is a copolymer of olefins and anhydrides contg. double bonds and/or a polymer contg. unsatd. polyester gps.. - The process avoids drawbacks resulting from monomer radi...
