An apparatus for the production of a synthetic resin skin uses a mold for forming at least two separate skin sections which are then joined prior or after a final heat treatment. The synthetic resin skin sections are produced in at least two separate mold members, and the skin sections are then caused to contact each other along determined faces or margins which are joined under light pressure. An...

An optical sensor apparatus receives visible light and converts that light to electrical signals for use by a control system. Visible light enters the apparatus through a hemispherical "fisheye" lens which provides a 360 DEG field of view in azimuth and a 180 DEG field of view in elevation. The light exiting the fisheye lens is projected through a shutter mechanism onto a receptor of a camera. Th...

Acylated chitin derivatives prepared by acylating a soluble derivative of chitin using an organic acid anhydride hitherto have not been able to effectively adsorb or separate substances with a molecular weight greater than 70,000. This problem has now been overcome by effecting acylation in the presence of a diluent, a porosity-regulating agent and one or more surfactant so as to obtain a porous a...

A process which improves the handleability of resilient, acrylic graft rubber particles which comprises coagulating the rubber particles, then contacting the coagulated particles in the coagulation medium with a dispersion of a non-resilient alkyl methacrylate resin and coagulating the alkyl methacrylate resin on the surface of the rubber particles. The particles of alkyl methacrylate resin adhere...

PURPOSE:To obtain a fine Nb3Sn superconductive wire having multi-cored structure by subjecting a small-sized ingot which contains less segregation and impurities and has excellent workability to cold working and aggregating many sets of many assemblies of such worked materials and Sn (alloy) thereby constituting the composite body equiv. to a large-sized ingot. CONSTITUTION:Many pieces of the Nb b...

A process for treating a stone surface is disclosed. Stone floor surfaces, such as, marble and terrazzo, are treated with an acid conditioner followed by buffing with a crystallizing agent whereby a durable, high gloss finish is produced in situ on the floor surface.

The surface of a shaped article of a vinyl chloride-based resin is subjected to two-step exposure to low temperature plasma produced in low pressure gaseous atmospheres. One of the two steps is performed in an atmosphere of a nitrogen-containing organic compound such as an amine, amide or diamine. The other step is performed in an atmosphere of an organic silicon compound such as an alkoxy-contain...
