  • Patent number: 6316052
    Abstract: A method for the surface treatment of vacuum materials reduces the H2O sticking probability on the surface of the vacuum material. The H2O sticking probability is reduced by selectively depositing silicon oxide, for example, and covering the regions which are in an active state on the surface of the vacuum material, and by setting the coverage to less than 100% of the state where film formation is achieved. If the abovementioned coverage is within the range from 40 to 80%, then it is possible to reduce the H2O sticking probability to a minimum.

  • Patent number: 6296695
    Abstract: The method and formula for tinting glass described herein employs a transparent acetate lacquer. The transparent acetate lacquer is derived from a base of cellulose acetate dissolved in an appropriate solvent. Preferably, additional ingredients are added to the formula to provide a lacquer that is easy to apply and which provides superior adhesion to the glass. The method of this invention includes applying a transparent acetate lacquer to glass and allowing the lacquer to dry. Application of the lacquer may be conducted by any conventional method including spraying and brushing. When dried, the lacquer provides excellent tinting properties.

  • Patent number: 6287636
    Abstract: A coating apparatus comprising a plurality of paint supply devices, a mouthpiece for dispensing a paint supplied from the paint supply devices, and a stage for holding a coated object. The mouthpiece comprises a plurality of outlet ports. Also, a coating method comprising relatively moving a mouthpiece and a coated object to coat the coated object with paint in which a diluent is added to the paint to form a paint/diluent mixture upon the start of the coating process. This paint/diluent mixture is used to coat the coated object upon the start of the coating process and until the process reaches a steady state. The flow of diluent is then stopped and the coating process is continued using only the paint in a steady state coating process. The flow of diluent is then started again to form a paint/diluent mixture as the coating process ends. A coating with a highly uniform thickness along the entire length of the coated object is produced by this method.
