Patent number: 7205024Abstract: Prior to transfer of an wafer W, a mixed gas is being generated and exhausted, thereby fluctuation of concentration and temperature of a solvent component at the beginning of gas introduction into a chamber 3 is suppressed. A step of gelling after the wafer W is carried into an aging unit is divided into several steps. Until a temperature of the wafer W reaches a predetermined treatment temperature, an average concentration of the solvent component in a mixed gas is gradually raised relative to the temperature of the wafer W. Thereby, immediately after the wafer W is transferred into a sealed chamber, the gas of the solvent component is prevented from condensing.Type: GrantFiled: February 5, 2004Date of Patent: April 17, 2007Assignee: Tokyo Electron LimitedInventors: Kazuhiro Takeshita, Shinji Nagashima, Makoto Muramatsu, Yoji Mizutani, Kazutoshi Yano, Kyoshige Katayama

Patent number: 7189285Abstract: Solutions comprising a sodium silicate waterglass having a modulus of less than 3 and at least 8% by weight of an organic polyhydroxy compound such as glycerol are useful in the production of interlayers used in fire resistant glass laminates. The solutions are dried on a flat surface such as glass to produce a clear intumescent interlayer having improved impact resistance. The dried interlayer may be removed from the surface in the form of an elastomeric material which may also be used as an interlayer in a fire resistant glazing.Type: GrantFiled: March 16, 2001Date of Patent: March 13, 2007Assignee: Pilkington PLCInventors: John Richard Holland, Karikath Sukumar Varma, David William Holden

Patent number: 6887367Abstract: The invention relates to a process which is suitable for applying a permanently adhering, stable, dirt and water repellent coating to metallic surfaces, specifically chromium surfaces, specifically sanitary and kitchen fixtures, and also to the components coated in this manner. The process is based on first chemically activating the surface and then coating it by means of a sol.Type: GrantFiled: July 10, 2002Date of Patent: May 3, 2005Assignees: Fraunhofer-Gesellschaft zur Forderung der Angewandten Forschung E.V., FEW Chemicals GmbHInventors: Siegfried Berg, Thomas Bolch, Friedrich Auer

Patent number: RE40517Abstract: Materials variously treated with sodium silicate were studied until enough information was obtained to find a way to solve the problems that have prevented sodium silicate from being the used as a fire retardant. These problems are: 1) water solubility (miscible with water), which results in extensive leaching when exposed to water, 2) cracking, chipping and peeling of treated surfaces, and 3) surface granulation. During flame tests it was discovered that sodium silicate formed a foam-like material, and this material was found to have become water insoluble, yet its elemental composition had remained virtually identical to that of the unmodified sodium silicate. This investigator proposes that under the influence of heat and dehydration, sodium silicate undergoes a polymerization process resulting in particles sizes too large to dissolve in water, and then developed a mechanism to explain how the process could occur.Type: GrantFiled: March 18, 2004Date of Patent: September 23, 2008Inventors: Robert A.
