    摘要: A thermal transfer printer has a platen and a thermal head between which are pinched a transfer paper sheet and an ink film, so that the ink is transferred from the ink film to the transfer paper sheet as heat is applied to the transfer paper sheet by the thermal head. The film is supplied by a supply roll and is taken-up by a take-up roll. The thermal head is swingable between a position where it contracts the platen and a position away from the platen. When the thermal head is in the position away from the platen, the distance therebetween is greater than the maximum diameter of the supply roll. A film drum can hold a plurality of films each being constituted by the supply roll and the take-up roll. Swing arms are provided for demounting the supply roll of a selected film from the film drum and for bringing the same to a position away from the film drum, and also for returning the same from this position to the film drum. During the movement of the supply roll between the position in the film drum and the position away from this position, the thermal head is moved away from the platen so as not to hinder the movement of the supply roll.

    摘要: In a dynamoelectric machine having a stator assembly of coil windings and a core, a heat-dissipating, uninflammable, electro-insulative housing encapsulates the coil windings and the core. The housing is made of a cured molded article or material formed of a resin-filler composition which comprises a liquid unsaturated polyester resin, a finely divided calcium carbonate powder, an inorganic mineral particulate having a particle size larger than that of the calcium carbonate powder, a chopped glass fiber and an aluminum hydroxide powder, wherein the ratio by weight of the calcium carbonate to the mineral particulate is 0.3 to 4, the ratio of the weight of glass fiber to the total weight of the composition is 0.05 to 0.25, the ratio of the weight of the polyester resin to the total weight of the composition is 0.1 to 0.4, the weight ratio of the calcium carbonate powder, the mineral particulate and the glass fiber to the total weight of the composition is 0.15 to 0.80, and the weight ratio of the aluminum hydroxide powder to the total weight of the composition is 0.1 to 0.6.
