    摘要: A process for the production of molded product composed of transparent resin having highly cured cross-linked structure comprises the following three steps:1. the step incorporating a ring-opening and cross-linking catalyst in the initial monomer composition, followed by vinyl-polymerizing the initial monomer composition in a mold into a vinyl polymer at 90% or more conversion by irradiating said composition with an ionizing radiation at such a low temperature that said catalyst is not decomposed,2. the step molding the vinyl polymer thus obtained into the desired shape, and3. the step heating the molded product at a temperature of from about 50.degree. C to about 200.degree. C to highly-cure the molded polymer product by the introduction of cross-linking.

    摘要: A work mounting apparatus according to the present invention comprises a rotating drum divided into upper and lower drums, a head unit arranged on the outer periphery of the rotating drum or the lower drum, a circular work head attached to the head unit, and a suction nozzle protruding from the outer peripheral surface of the work head toward a workbench. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture or orientation kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench. The work mounting apparatus further includes a balance weight for the work head, and a friction brake for applying a frictional force to the turning shaft of the work head, to thereby stabilize the turning motion of the work head.

    摘要: A novel thermosetting resin composition comprising at least one [(2,3-epoxypropoxy)alkyl]trialkoxysilane and at least one selected from polymers, prepolymers, copolymers and coprepolymers of epoxy-group-containing vinyl monomers, which may further contain at least one selected from polymers, prepolymers, copolymers and coprepolymers of vinyl monomers containing no epoxy group, is disclosed. This composition is cured by heating with addition of a ring-opening polymerization catalyst and remarkably improves surface hardness, abrasion resistance, weathering resistance, chemical resistances, heat resistances, etc. of acrylic resins and many other plastic materials without imparing the inherent transparency and other optical properties of these materials when it is applied on the surface of them and cured.
