Abstract: A capacitor of the present invention employs one of i) polyimide directly formed by electrodeposition, ii) organic high polymer having a specific structure formed by electrodeposition, and iii) a composite film of the organic high polymer and oxide film of a conductor as dielectrics formed on the surface-roughened conductor. The organic high polymer used in the present invention contains carboxylic radical in its molecular structure. The capacitor of the present invention further comprises an opposite electrode at least containing conductive high polymer on the dielectrics. This conductive high polymer is formed by chemical oxydation-polymerization or both chemical oxydation-polymerization and electro-polymerization. The capacitor element as configured above is strong to mechanical stress, and possible to apply pressure during lamination.

Abstract: Soundproofing materials consisting essentially of zinc oxide whisker particles having a nucleus body and needle crystal portions extending radially from the central body in different plural directions. The materials may comprise a support material for supporting the zinc oxide whisker particles. Such support materials include inorganic materials such as metals, ceramics, glasses, cements, mortars and various fillers in the form of powder, flakes, fibers and the like, and organic materials such as resins, rubbers, waxes and the like. These materials are particularly suitable for sound insulation, sound proofing, vibration damping and vibration insulation.

Abstract: A novel zinc oxide crystal has an octahedral nucleus whose faces are alternately zinc faces and oxide faces, and this crystal has such a geometric shape that a needle is grown on each of the faces. The needle grown on the oxide face is branched into three sections which are disposed in parallel relation, and the needle on the oxide face is shorter than the needle on the zinc face. This novel crystal having oxide films can be produced in a homogeneous manner by mixing zinc-tin alloy powder or tin powder with zinc powder, having an oxide film formed on each particle thereof, to form a powder mixture and then by heating the powder mixture at 820.degree. C. to 1100.degree. C. in an oxidizing atmosphere to oxide the same. The tin concentration in the power mixture is less than 40 wt. %.

Abstract: The present invention provides a method for manufacturing zinc oxide whiskers, whereby zinc powders composed of particles coated with an oxide film, preferably an oxide film having a superior sealing property are, heated for oxidization in an atmosphere containing oxygen.The atmosphere may contain carbon dioxide or steam.The obtained zinc oxide whiskers are formed in a single crystal comprised of a core part and an acicular part spreading in four different directions from the core part.For a baking furnace to obtain zinc oxide whiskers, is employed one that successively forms an atmosphere of a high partial pressure of zinc steam at the source side and an atmosphere of a high partial pressure of oxygen for facilitating formation of whiskers. The zinc oxide whiskers can be controlled in size by selecting the relative ratio of the partial pressure of zinc steam and oxygen.

Abstract: A photoconductive cell comprises a photodetector section which consists of an aggregate of tetrapod-like zinc oxide whiskers. Each whisker consists of a core and needle-shaped crystals extending in four different directions from the core. Since this novel tetrapod-like zinc oxide whisker consists of single crystal zinc oxide, it suffers less deterioration. In addition, since the single crystals are transparent and an aggregate thereof has a high porosity, light tends to enter deep portions of the cell so that it exhibits high sensitivity.

Abstract: Whiskers of zinc oxide whose crystal structure includes a central body and four needle crystal projections radially extending from said central body are described. The whiskers are so unique a structure that they are applicable to various materials such as metals, resins, ceramics and the like as a reinforcing material. The whiskers may be in the form of a mixture of whiskers of zinc oxide having crystal structures including two, three, four and/or five needle crystal projections. A method for preparing such whiskers is also described.

The whiskers comprise at least one needle crystal having a basal part whose diameter is from 0.7 to 14 micrometers and a length from the basal part to its tip of from 3 to 200 micrometers. The metal composition is isotropically reinforced with respect to mechanical strength and is significantly improved in free cuttability.
