The coating composition produces a coating having a glass transition temperature of from about 50 DEG to about 150 DEG C., a Sheffield surface smoothness of 28 to 50 and, when applied to both sides of the plastic film will generate an opacity of at least 75%. The ...

PURPOSE:To attain sufficient supervision of runaway by discriminating it as program runaway when an execution address is not in use at the execution of program or fetch of an instruction code is detected from a program dismounting address. CONSTITUTION:When a CPU 1 accesses an optional address, logical L is outputted respectively to a terminal RD' or WR' from the CPU 1. An output of a NOR gate 10 ...

DYNAMIC RANDOM ACCESS MEMORY REFRESH CONTROL SYSTEM A system and method are disclosed for automatically refreshing a dynamic random access memory (DRAM) under a plurality of different operational conditions of an associated processor. In a preferred embodiment of the invention, when the processor is normally executing instructions it generates active signals. These active signals enable a generato...

A method of producing a drive shaft with drive elements on a cylindrical basic part includes forming a desired contour for a drive element on pairs of discs, forming holes in the discs of each pair having axes being inclined relative to the surfaces of the discs and having inclinations being opposite to and mirror images of each other, pushing the discs onto a cylindrical basic part with the disc ...

A method of preparing fine polyorganosiloxane emulsions with an average particle size of less than 0.3 micron and polyorganosiloxane microemulsions with an average particle size of less than 0.14 micron is described. A translucent oil concentrate is prepared by mixing a polyorganosiloxane which contains polar groups, a surfactant which is insoluble in the polyorganosiloxane, and sufficient water t...

A cellulosic particle, especially useful as a cat litter, is manufactured by agglomerating a fibrous cellulosic feed material in the presence of water, compacting the surface of the agglomerated particles, and drying the particles.

Polypropylene films having a coextruded ethylene-vinyl alcohol (EVAL) layer cannot be readily oriented because the orientation temperature for the EVAL layer is somewhat higher. By adding an aryl sulfonamide, such as p-toluenesulfonamide to the EVAL layer its orientation temperature is reduced enabling orientation of the composite film.

Methods of making low density modified polyimide/polyimide-amide foams and the resulting compositions. An N-substituted aliphatic imide is prepared by reacting a suitable aromatic dianhydride with a suitable oxime. A polyimide forming material is prepared by dissolving the N-substituted aliphatic imide in an esterifying solvent, then adding a suitable aromatic diamine. This material is dried to a ...

The tear strength of biaxially oriented polypropylene is improved by adding polyethylene, e.g., about 5-40 weight percent, and an ethylene propylene rubber, e.g., about 1-10 weight percent.

Method for improving the strength and impermeability of soils and engineering structures by forming a hydrogel composed of silicic acid and a cross-linked swellable organic polymer in or on the soil or structure treated. According to the invention an aqueous solution of a silicic acid gel precursor is contacted with a water-soluble gel-forming vinyl monomer in the presence of a redox polymerizatio...

PURPOSE:To prepare a large size original printing plate, by dividing an original pattern into plural enlarged partial original plates by photographing and applying these partial original plates to a layout sheet to form a continuous pattern, and printing the pattern on a photosensitive material using a mask plate having registering means.
