    • In manufacturing molded product of urethane foam, a releasing agent mainly composed of organopolysiloxane is applied on the inner surface of the mold maintained at 60.degree. C. The agent is prepared by dissolving the base composed of organopolysiloxane composition in an organic solvent. The organopolysiloxane composition comprises (a) a first organopolysiloxane of which 0.1 to 5.0% of all organic groups bonded with Si atoms are vinyl groups and at least 80% of the remaining organic groups are methyl groups, and (b) a second organopolysiloxane containing at least three Si bonded hydrogen atoms in one molecule, wherein the first and second organopolysiloxanes contain Si vinyl groups and SiH groups at a ratio in a range of 1:0.5 to 1:5, and do not substantially contain unreactive siloxane. The agent is cured by irradiation with ultraviolet rays, and a thin and uniform film of releasing agent is formed on the inner surface of the mold. Inside the mold coated with this film of releasing agent is injected a raw liquid of urethane foam of cold cure-type, and after the curing step, a molded product of urethane foam in a desired shape is manufactured.
    • 在制造聚氨酯泡沫塑料的成型体中,将主要由有机聚硅氧烷组成的脱模剂施加在保持在60℃的模具的内表面上。该试剂通过将由有机聚硅氧烷组合物组成的基体溶解在有机溶剂中来制备。 有机聚硅氧烷组合物包含(a)第一有机聚硅氧烷,其中与Si原子键合的所有有机基团的0.1至5.0%为乙烯基,并且至少80%的剩余有机基团为甲基,和(b)第二有机聚硅氧烷, 一个分子中至少三个Si键合的氢原子,其中第一和第二有机聚硅氧烷以1:0.5至1:5的比例含有Si乙烯基和SiH基,并且基本上不含有未反应的硅氧烷。 通过紫外线照射固化剂,在模具的内表面形成薄膜均匀的脱模剂膜。 在涂有该脱模剂膜的模具内注入冷固化型聚氨酯泡沫的原液,在固化步骤之后,制成所需形状的聚氨酯泡沫的成型体。

    • The present invention provides flexibility in the shape and material of the cleaning vessel, enables high-power transmission of ultrasonic waves, and reduces audible noise generation. An ultrasonic cleaning machine according to the invention comprises an acoustic lens mounted above an ultrasonic transducer which is immersed in oil held within an external tank as well as a cleaning vessel holding a cleaning liquid further above the acoustic lens so that ultrasonic waves produced by the ultrasonic transducer converge at a point within the cleaning liquid. In one form of the invention, the cleaning vessel is eliminated and the cleaning liquid is held directly in the external tank.
    • 本发明提供了清洁容器的形状和材料的灵活性,能够实现超声波的大功率传输,并且减少了可听见的噪声产生。 根据本发明的超声波清洗机包括安装在超声波换能器上方的声透镜,该超声波换能器浸入到保持在外部罐内的油中,以及保持在声透镜之上的清洁液体的清洁容器,使得由超声波产生的超声波 换能器会聚在清洁液体内的一个点处。 在本发明的一种形式中,清洁容器被清除,清洗液体直接保持在外部罐中。
