  • Process and apparatus for controlling bacterial contamination of medical unit waterline and water therein using electric current
    Publication number: 20030044310
    Abstract: An anode electrode is disposed to expose in water in a medical waterline, and a cathode is connected to an outer surface cf the waterline electrically conducting to an inner surface of the waterline or exposed in water in the waterline, and by these electrodes, an electric current of an output within the range from 3 to 50 mA is applied to water in the waterline, thereby providing an electric current sterilization method for the medical waterline and water therein, with improved cost effectivity, safety, and sufficient sterilization characteristic.

  • Coating composition for plastic substrates
    Patent number: 4214057
    Abstract: A coating composition comprising (A) a hydrolyzed product obtained from a tetraalkoxysilane, (B) a hydrolyzed product obtained from a silicon compound of the formula, R'Si(OR").sub.3, wherein R' and R" are as defined in the specification, and (C) a poly(vinyl acetate) resin gives excellent physical and chemical properties such as hardness, wear resistance, scratch resistance, etc., to the coated film, when it is coated on shaped articles particularly made from plastics such as methacrylate resins.

  • Powder molding process for producing thermoplastic articles
    Patent number: 3969475
    Abstract: A novel powder molding process for producing thermoplastic articles having improved surface properties and the molded articles produced thereby. Molding compositions comprising a thermoplastic polymer in the powder state and a curable additive selected from the reactive monomers and prepolymers thereof, which are liquid at the melting or softening temperatures of the thermoplastic polymers, are subjected to powder molding wherein the heating rate of the molding composition during the linear portion of the temperature-time curve after the initiation of melting or softening of the thermoplastic polymer is maintained at a very low rate, i.e., less than 25.degree.C. per minute. A curing agent may be added to the molding composition in order to control the curing time of the curable additives. The obtained thermoplastic articles have a cured thin surface layer of the curable additives, said surface layer being strongly combined with an inner layer of the thermoplastic articles.
