Patent number: 6461689Abstract: The specular gloss of a polyurethane wear layer of a surface covering is controlled by controlling the thermal conditions of a substrate before and after it is coated with a liquid polyurethane and by controlling the termal conditions of the liquid polyurethane before it is coated on the substrate. The liquid polyurethane is photo-curable or radiation-curable and it contains a matting agent. Changes in specular gloss are attained without changing the composition of the polyurethane or the conditions of photo-curing or radiation curing.Type: GrantFiled: August 31, 2000Date of Patent: October 8, 2002Assignee: Domco Tarkett Inc.Inventors: Martin Gauthier, Claude Charest, René Ménard, Jean-François Courtoy

Patent number: 6458431Abstract: A method for depositing nanoparticles in a thin film through the dispersion of such nanoparticles in a precursor solution which is deposited on a substrate and converted into a metal or metal oxide film. The resulting metal or metal oxide film will contain embedded nanoparticles. Such films can be used in a variety of applications such as diffusion barriers, electrodes for capacitors, conductors, resistors, inductors, dielectrics, or magnetic materials. The nanoparticle material may be selected by one skilled in the art based on the particular application.Type: GrantFiled: July 30, 2001Date of Patent: October 1, 2002Assignee: EKC Technology, Inc.Inventors: Ross H. Hill, Juan Pablo Bravo-Vasquez

Patent number: 6410107Abstract: Methods for manufacturing an electrostatic actuator that comprises electrode members having opposing surfaces with a gap disposed therebetween. In an ink jet head, a bottom surface of a diaphragm may be one of the electrodes (common electrode) of an eletrostatic actuator, the diaphragm forming a wall of an ink chamber in the ink jet head that is displaced relatively by an electrostatic force. A hydrophobic film, preferably hexamethyldisilazane (HMDS), is formed on at least one of the opposing electrode surfaces to improve the durability of the electrostatic actuator so that electrostatic attraction between opposing electrode members does not decrease and the opposing electrode members do not stick together. HMDS molecules are smaller than PFDA molecules, and a uniform, variation-free hydrophobic film can therefore be formed even when the gap between opposing electrodes is narrow. Durability and film stability of a HMDS hydrophobic film are also high.Type: GrantFiled: November 30, 2000Date of Patent: June 25, 2002Assignee: Seiko Epson CorporationInventors: Kazuhiko Sato, Hiroyuki Maruyama, Masahiro Fujii, Tadaaki Hagata, Koji Kitahara, Keiichi Mukaiyama
