    • This invention is a method for forming a protective, strippable, elastomeric film on a highly reflective surface. The method is especially well suited for protecting diamond-machined metallic mirrors, which are susceptible not only to abrasion and mechanical damage but also to contamination and corrosion by various fluids. In a typical use of the invention, a diamond-machined copper mirror surface is coated uniformly with a solution comprising a completely polymerized and completely cured thermoplastic urethane elastomer dissolved in tetrahydrofuran. The applied coating is evaporated to dryness, forming a tough, adherent, impermeable, and transparent film which encapsulates dust and other particulates on the surface. The film may be left in place for many months. When desired, the film may be stripped intact, removing the entrapped particulates and leaving no residue on the mirror surface.
    • 本发明是在高反射性表面上形成保护性,可剥离的弹性体膜的方法。 该方法特别适用于保护金刚石加工的金属镜,这不仅易受磨损和机械损伤的影响,还可能受到各种流体的污染和腐蚀。 在本发明的典型用途中,金刚石加工的铜镜表面用包含溶解在四氢呋喃中的完全聚合和完全固化的热塑性聚氨酯弹性体的溶液均匀地涂覆。 将涂覆的涂料蒸发至干,形成坚固,粘附,不渗透和透明的膜,其将表面上的灰尘和其它颗粒包封。 这部电影可能会留下好几个月。 当需要时,可以将膜完全剥离,除去捕获的颗粒并且在镜面上不留下残余物。

    • PROBLEM TO BE SOLVED: To automate assembly packaging of a napkin and an eating tool while continuously rotating an injection molding machine to enable labor saving, improvement in productivity and stabilization in quality by including the injection molding machine, a napkin folding machine, an automatic packaging machine and a robot for transferring and supplying the eating tool molded by the injection molding machine to the automatic packaging machine. SOLUTION: There is not a little variation in production time intervals. Therefore, speed is adjusted on a side of a packaging machine conveyer 32, and the adjusted information is transferred to a robot 5, a napkin folding machine 2 and a packaging machine body 3A for performing matching correction. The napkin folding machine 2 and an automatic packaging machine 3 adjust speed while continuously operating for interlocking with continuous operation of an injection molding machine 1. Thus continuous operation of the injection molding machine 1 which varies in production time is allowed by timer control or the like, so that a napkin and an eating tool are arranged on the packaging machine conveyer 32 while speeds of the napkin folding machine 2, the automatic packaging machine 3 and the robot 5 are corrected. Therefore manual supply of napkins is eliminated to save labor.
