Abstract: A process for producing a heat-insulating cavity mold, characterized by producing two members, i.e., a metallic surface layer member (1) for forming a metallic surface layer (5) of a cavity mold in a mold for thermoplastic resin molding and a cavity mold main body member (9) for forming the cavity mold, forming a heat-insulating layer (10?) on a bonding surface of the member (9), bonding the two members to each other, and subsequently eliminating an unnecessary part (3, 12) of the metallic surface layer member to form the metallic surface layer (5); a heat-insulating cavity mold; and a mold for thermoplastic resin molding which employs the cavity mold.

Abstract: An adhesive tape comprising a substrate and an adhesive agent layer formed on one surface of the substrate; wherein a shape of non-adhesive section having an edge in a width direction of the adhesive tape as a part of an outer periphery of the shape of non-adhesive section is formed consecutively in a length direction of the adhesive tape, in at least one edge region in the width direction of the adhesive tape on a surface thereof on which the adhesive agent layer is formed, and an area fraction of the non-adhesive sections on the surface on which the adhesive agent layer is formed is in the range of from 1 to 40%, is good in adhesive characteristic and peelability; and further, good in loading stability on the adherent to which it is adhered.

Abstract: A mold for injection molding of a thermoplastic resin. The mold comprises a cavity block, a core block, and a cavity formed between the cavity block and the core block and adapted to be filled with a molten resin. The cavity block includes an insulating layer on a cavity side thereof, the insulating layer being made of a material selected from the group consisting of ceramic materials, porcelain enamel, glass materials, heat resistant plastic materials and their composites. The core block includes a release insulating layer on a cavity side thereof, the release insulating layer being made of a material selected from the group consisting of fluorocarbon resins, fluorocarbon resin composite materials, silicone resin composite materials and metal platings with fluorocarbon resin dispersion, the release insulating layer further being adapted to effect both mold releasing and heat insulation.

Abstract: A data transfer unit for a small computer system which has a host computer and main and auxiliary storage units, transfers data between the host computer, and the main and auxiliary storage units. The data transfer unit transfers the data, which is outputted from the host computer, from the data buffer to both the main and auxiliary storage units simultaneously, in an operation mode in which data is transferred from the host computer to the storage units. When an error occurs in the main or the auxiliary storage unit, the data transfer unit transfers the correct data from the other storage unit which is operating normally, to a substitute address in the storage unit in which the error has occured.

Abstract: An element having a molding surface defining the cavity of a mold for molding thermoplastic resin and a method of making the element. To regulate the cooling speed of the molten resin to be injected or placed into the cavity, the molding surface is provided by a thin metal layer and a layer of heat insulating material is formed on the inner side of the metal layer.
