    摘要: An epoxy resin composition having a remarkably improved storage stability and an excellent hardening characteristic when heated, which comprises an epoxy resin and an aromatic amino carboxylic acid or a derivative thereof as a hardener for the epoxy resin. This composition can be molded by injection molding, heretofore being deemed inapplicable to epoxy resin compositions, whereby the molded articled of epoxy resin can be produced with a high molding efficiency.

    摘要: A thin film multilayer wiring board-producing method of the present invention is intended to decrease thermal stresses developing during the formation of the multilayer construction, and also to greatly reduce the number of the steps of the process, as compared with a conventional method. A film material can be used as an insulating film of the multilayer wiring board, and is adhesively bonded to a predetermined portion. Wiring conductors are formed by electroplating. The wiring layers are repeated laminated to form the multilayer construction. A metallic film serving as an electrode is formed on one of upper and lower surfaces of a substrate, the metallic film being removed after a multilayer wiring is formed. A soluble insulating film is formed on a metallic undercoat film on the substrate, and grooves are formed in the soluble insulating film, and wiring conductors are formed in the grooves, using either electroplating or both electroplating and electroless plating. Thereafter, the soluble insulating film and the metallic undercoat film are removed. Subsequently, an insoluble insulating film is formed at those locations from which the soluble insulating film and the metallic undercoat have been removed.

    摘要: A method of and an apparatus for molding a plastic wherein the injection pressure (transfer pressure) is switched to a holding pressure when the internal pressure of the mold cavity sensed by a pressure sensor reaches a predetermined injection pressure (transfer pressure), to initiate holding of the pressure applied to the cavity. The holding pressure is removed when the internal pressure thereof becomes zero or in accordance with the detection of a predetermined inflection point in the internal pressure which is indicative of a gate sealing point in the mold cavity or is brought to a predetermined value close to zero. The molded articles are of high precision finishes, and conservation of energy and natural resources can be achieved.
