Abstract:
The present invention provides a method of forming a conductive pattern, comprising the steps of: (1) applying a positive, energy-sensitive paste composition containing a conductive powder to a substrate, followed by drying, to form a positive, energy-sensitive coating, (2) irradiating the coating with active energy rays or heat rays directly or through a mask so as to obtain a desired pattern, and (3) removing the irradiated part of the coating by development to form a conductive pattern coating; and a method of forming a conductive pattern, wherein the above paste composition is applied to a release film and dried, and using the resulting dry film, a conductive pattern coating is formed in a manner similar to the above.
Abstract:
The invention relates to a process for the coating of a wooden, wood-like and/or cellulose-containing substrate comprising the steps of: a) applying a press coating to the substrate; b) applying heat and pressure to the coated substrate to cure the press coating and to obtain a substrate with a smooth coating film, with the pressure being such that the substrate is not substantially compressed; c) applying a top coat on the substrate after the curing of the press coating; and d) curing said top coat. As a result of this process, the amount of unreacted double bonds in the coated substrate is at a low level.

Abstract:
Magnetic composites exhibit distinct flux properties due to gradient interfaces. The composites can be used to improve fuel cells and effect transport and separation of different species of materials. A variety of devices can be made utilizing the composites including a separator, a cell, an electrode for channeling flux of magnetic species, an electrode for effecting electrolysis of magnetic species, a system for channeling electrolyte species, a system for separating particles with different magnetic susceptibilities. Some composites can be used to make a dual sensor for distinguishing between two species of materials and a flux switch to regulate the flow of a redox species and a flux switch to regulate the flow of a chemical species. Some composites can control chemical species transport and distribution.
Abstract:
A treatment method for the internal surface of a moulded polyethylene plastics material container such as a drum, comprising the steps of: introducing an ionisable gas, such as argon, into the container; generating a plasma of the introduced gas by applying electric field of sufficient strength to the container and introduced gas, so as to cause an interaction with the internal surface of the container; coating the internal surface of the container with a curable epoxy-based first polymeric composition; and then curing the polymeric composition to form a coating on the internal surfaces of the container. A second coating, preferably with electrical conductive properties, may be applied and cured over the first coating. Conductive properties may provided by including conductive particles such as antimony doped tin dioxide, graphite or metal powders, in the second composition.

Ethylene copolymer elastomer compositions, acrylate rubber compositions, nitrile rubber compositions, fluoroelastomer compositions, and chlorinated elastomer compositions are provided which are curable by exposure to UV radiation. The compositions are particularly suited for production of elastomeric seals using hot melt equipment and a gasketing in place technique.
Abstract:
A laser marking apparatus and method for marking the surface of a semiconductor chip are described herein. A laser beam is directed to a location on the surface of the chip where a laser reactive material, such as a pigment containing epoxy, is present. The heat associated with the laser beam causes the laser reactive material to fuse to the surface of the chip, creating a visibly distinct mark in contrast to the rest of the surface of the chip. Only reactive material contacted by the laser fuses to the chip surface, and the remaining residue on the non-irradiated portion can be readily removed.
