Patent number: 6969538Abstract: The present invention relates to a method for heat processing a substrate. After a coating film is formed on the substrate, the substrate is baked at a predetermined high temperature. The baking step is performed by first increasing the substrate temperature from a predetermined low temperature to a predetermined intermediate temperature that is lower than a predetermined reaction temperature at which the coating film reacts. Next, a second baking step maintains the substrate at the predetermined intermediate temperature for a predetermined period of time, and is followed by a third step of increasing the temperature of the substrate to the predetermined high temperature that is higher than the predetermined reaction temperature. This results in uniform temperature within the surface of the substrate when the temperature of the substrate reaches the reaction temperature. Consequently, a chemical reaction due to heat processing of the coating film within the surface of the substrate is performed uniformly.Type: GrantFiled: September 7, 2001Date of Patent: November 29, 2005Assignee: Tokyo Electron LimitedInventors: Masatoshi Deguchi, Eiichi Sekimoto, Koichi Asaka, Yuji Matsuyama

Color coated landscape stones, surface coating, preparations therefor, and methods of producing same
Publication number: 20020006481Abstract: Vibrantly colored stones for use as decorative landscape elements are disclosed. The invention includes a process, including coating formulations, apparatus, and a method for preparing and applying specific acrylic-based color coatings to river rocks, stones, and the like thereby resulting in brightly colored decorative stones suitable for use in landscaping. End use stabilizers prevent color degradation, while the addition of faceted grains of mineral material enhance visual appearance. Colored stones produced according to the process herein are durable, colorfast, non-toxic, mildew resistant, algae resistant and otherwise environmentally safe. The stones may be used as decorative elements in a wide variety of landscape settings.Type: ApplicationFiled: January 3, 2001Publication date: January 17, 2002Inventor: Barrington A. Morris -
Patent number: 6339117Abstract: The present invention relates to polymers whitened with optical brighteners obtained by (a) emulsion polymerization of acrylonitrile with or without a comonomer in the presence or absence of a graftable substrate, and (b) addition of an optical brightener before, during, or after the emulsion polymerization.Type: GrantFiled: February 28, 2000Date of Patent: January 15, 2002Assignee: Bayer AktiengesellschaftInventors: Udo Eckstein, Siegfried Korte, Ulrich Feldhues, Hans-Peter Geiger, Bernhard Hunke, Thomas Roick, Günter Sackmann
