Abstract: The present invention is to provide an adhesive composition which comprises a copolymer A which contains a recurring unit having a cyclic ether structure and a recurring unit having a benzophenone structure, and a copolymer B which contains a recurring unit having a betaine structure and a recurring unit having a hydroxyl group, a cured product thereof, and a method for producing the cured product. The adhesive composition of the present invention is capable of curing in water, has high hydrophilicity, and is capable of forming a cured product having an excellent ability to inhibit adhesion of biological substances.

Abstract: Provided is a method of producing a polymer-impregnated base resin which is excellent in providing low adsorption of proteins and blood cells such as platelets. The method of producing a polymer-impregnated base resin includes impregnating a base resin with a polymer solution that includes a solvent able to swell the base resin.

Abstract: An anisotropic conductive film (14) and circuit elements (16) are superimposed and disposed on a substrate (10). An isotropic pressing operation is performed by a pressing mold having a flexible layer (22) on the surface to be brought into contact with the circuit elements, and simultaneously heating is performed to bond the circuit elements onto the substrate. Since the flexible layer absorbs differences in thickness of the circuit elements, the plurality of circuit elements can be pressed simultaneously. Further, since the plurality of circuit elements are simultaneously heated, it is unnecessary to consider an influence of heat on unheated adjacent circuit elements in a case where the elements are heated one by one. The isotropic pressing makes it possible to prevent the anisotropic conductive film from protruding sideways. As a result, spaces between the circuit elements can be reduced.

Abstract: A press-forming apparatus is disclosed in which a preform such as green sheets, for example, is charged into a cavity in a pressure container, the cavity is covered with a lid member, and the green sheets are pressed by a pressure medium while the green sheets are heated by heating means, whereby the green sheets are press-formed into an integral laminated product. The pressure force should preferably be fluctuated during the pressing operation.

Abstract: A tape wrapping mechanism in a magnetic recording/reproducing apparatus comprises guide elements for wrapping a recording medium tape onto a head drum, a cam member (3) provided with a cam rift, cam follower following the cam rift to drive the guide elements, and motor (21) for driving the cam member. The mechanism further comprises a loading ring (6) on which members (61) for drawing out the guide element are provided. The guide elements are driven alternately by the cam member (3) and the loading ring (6).
