摘要:
Adhesive compositions of a selected class of epoxy resins combined with a selected class of carboxylic group-containing acrylonitrile-butadiene and methacrylonitrile-butadiene copolymers, maleimide derivatives and an imidazole compound. The resultant compositions are electrically insulative, thermally resistant, highly capable of fabrication at low pressure and storage stable.

By using a composite film comprising an additive layer and an insulating layer containing an epoxy resin and a synthetic rubber as major components, printed wiring boards having a higher circuit density and higher reliability can be produced simply and effectively.
摘要:
Composite films for use in printed wiring boards are comprised of an insulating layer and a copper foil laminated thereover, the insulating layer being made up predominantly of a selected epoxy resin and a selected acrylonitrile-butadiene rubber, whereby voidlessness, thickness uniformity and insulation adjustment are enhanced. Also disclosed is a method of producing a printed wiring board using the film by a subtractive process.

摘要:
A metal terminal adapted to be fixedly held between a terminal connecting portion and a fastening member provided at the terminal connecting portion, the metal terminal comprising an electrical contact portion which can be slid to be inserted between the fastening member and the terminal connecting portion so as to be connected to the terminal connecting portion; a wire connecting portion which extends from the electrical contact portion, a wire being adapted to be connected to the wire connecting portion; and an upstanding piece portion which is provided so as to extend in an upstanding manner from the electrical contact portion, and is disposed rearwardly of a connection part of the electrical contact portion in a direction of sliding of the electrical contact portion. The connection portion of the electrical contact portion is adapted to be held between the fastening member and the terminal connecting portion.
摘要:
The invention relates to processes for removing chlorate salts from an aqueous alkali chloride solution employed in cation-exchange membrane electrolysis, comprising the steps of adding hydrochloric acid to an aqueous alkali chloride solution to form a reaction solution, and maintaining the absolute pressure of the reaction solution at a range not higher than 600 mmHg and not lower than the saturated vapor pressure of the solution in a decomposition vessel and/or feeding the reaction solution to the bottom portion of a decomposition vessel and causing the reaction solution to flow upward in the decomposition vessel.
摘要:
A structure for screw-tightening and connecting a terminal to an electrical junction box is provided. The terminal mounting structure in the electrical junction box ensures mounting operation with an insertion direction of the terminal obliquely oriented, and prevents heating of the terminal due to power supply. The terminal is secured and connected to a busbar of the junction box by a bolt, with a head and a shaft of the bolt inserted into a vertical opening and a horizontal notched hole of the terminal, respectively. A pair of opposed guiding walls are provided on a junction box body at both sides of the bolt. The guiding wall includes an entrance's side sloping surface obliquely extending from top to bottom, and a straight horizontal surface continuing to the sloping surface. The terminal includes a pair of outward projecting pieces at an upper portion to be slid on the sloping surface and the horizontal surface. A heat release portion extends integrally at an upper portion of a vertical plate portion of the terminal having the vertical opening. Linear indentations are provided on front and back surfaces of the heat release portion to be exposed outside.
