    摘要： A process for producing a molding having an embedded member which comprises: a first step in which a mold (1) having pins (3) which extend from the outside to the inside of the mold and can be withdrawn outward is heated to a given temperature; a second step in which a member (2) to be embedded is held in a given position within the mold by supporting the member, including an upper part thereof, with the pins (3); a third step in which a thermoplastic resin is packed through a gate (1d) first into that part of the cavity of the mold (1) which is located under the member to be embedded to thereby cause the thermoplastic resin to press the member against the pin (3) located in an upper part of the mold; a fourth step in which the thermoplastic resin is packed into the remaining part of the cavity of the mold (1); and a fifth step in which the pins (3) are withdrawn successively from the lower side of the mold before cooling to a temperature at which the thermoplastic resin solidifies and loses its flowability.

    摘要： A novel epoxy resin composition is prepared by first mixing 100 parts by weight of an epoxy resin having an epoxy equivalent of no more than 200 with 0.5-10 parts by weight of a phenoxy resin to form a uniform mixture, then blending the mixture with a curing agent (i.e., a condensation product of a polybasic carboxylic acid and bisphenol A) and an inorganic filler. The epoxy resin composition has a suitable degree of rigidity and softness within the molecular chain without sacrificing its resistance to heat or thermal shock and will not cause precipitation of any portion of the filler in the resin composition. This resin composition is useful in the making of cast insulators employed in electric machines.

The epoxy resin (A) is a bifunctional brominated bisphenol A or a brominated bisphenol F, "epoxy resin and at least one bisphenol A, bisphenol F or bisphenol epoxy resin". The coupling agent (D) is selected from the group consisting of epoxysilane type coupling agents, phenylaminosilane type coupling agents, mercaptosilane type coupling agents and titanate type coupling agents, which has an average particle diameter of not more than 60 .mu.m and in which the content of particles having a diameter of not more than 5 .mu.m is not less than 5% by weight. The filler (E) comprises at least one of silica fillers or alumina fillers. The ratio of the number of acid anhydride groups of the acid anhydride (B) to the number of epoxy groups of the epoxy resin (A) is 0.5 to 1.5; the amount of the curing accelerator (C) is 0.5 to 10 parts by weight based on 100 parts by weight of the epoxy resin (A); the amount of the coupling agent (D) is 0.05 to 5 parts by weight based on 100 parts by weight of the filler (E); and the content of the filler (E) is 35 to 95% by weight of the resin composition. The epoxy resin composition has excellent mechanical properties such as high mechanical strength and toughness, and excellent thermal resistance.
