Abstract: A process for producing fibrous composite materials from feed stock formed reliminarily from a gypsum binder and chopped cellulose fibers, and saturating the mixture with water to the extent of at least 1.2 times its normal hydrated state, and beating the material to provide a fleece that is then spread on a flat surface and subjected to pressure for a sufficient length of time to drive out a substantial portion of the moisture from the product. The compression step is carried out long enough to achieve a bulk density of approximately 9/10 the dry bulk density of the components prior to hydration.

Abstract: A multi-layered web is produced by providing a first layer comprised of a strip of biaxially oriented polymeric film characterized by an inherent tendency to bend within its own plane. The strip is tensioned so as to overcome the bending tendency and assume a straight orientation. While the strips is held straight, a second layer of material is adhered to the strip. The second layer counteracts the bending tendency of the first layer so that when the tensioning forces are released, the web is straight. The first and second layers may comprise first and second strips of plastic film, respectively, which are arranged such that the bending tendencies of the strips are oriented opposite one another. The strips are adhered together by an adhesive material, or by being directly fused together. Alternatively, the second layer may comprise a coating applied to the plastic strip. The coating can be applied to one or both sides of the strip.

Abstract: A transparent film used as recording media in an electrophotographic apparatus and having different expansion and shrinkage characteristics during heating in length and width directions. At the end portion of the film in the direction in which the film has slighter shrinkage is provided a non-transparent member so that the passage of the film can be detected by means of photosensors without the non-transparent member being peeled away from the film due to the differences in the shrinkage factors of the film and the non-transparent member upon fixing.An image forming method for forming an image on the transparent film. In the above method, the transparent film is set at a supply portion of the electrophotographic apparatus so as to be fed along the direction in which the film has greater shrinkage during heating, so that the film does not jam and roll up on a fixing rollers and is allowed stable image formation.

Abstract: In an optical recording disk comprising a reflective layer in close contact with a recording layer, the recording layer contains a phthalocyanine dye and a second dye having a lower heat decomposition temperature than the phthalocyanine dye. By virtue of a depression of heat decomposition temperature, recording sensitivity is improved.

Abstract: A method in which a multi-layered ceramic circuit board made of a hybrid laminate consisting of green sheets containing hollow silica and green sheets containing no hollow silica is manufactured without failures occurring during the firing of the laminate. By incorporating quartz glass into a first ceramic material containing hollow silica to replace part of the hollow silica with quartz glass, the compositions of the first ceramic material and a second ceramic material containing no hollow silica are controlled so that the difference between the percentages of shrinkage on firing of the green sheets formed of the first and second ceramic materials is within 1%.

The increase in breakdown voltage is achieved by selecting an appropriate aluminum alloy and appropriate processing parameters. Sealing the anodic film increases the breakdown voltage by decreasing corrosion. A preferred sealant is an epoxy cresol novolac having a low room temperature viscosity that cures to a highly cross-linked polymer.
