Patent number: 7351449Abstract: Flame produced vapors for combustion chemical vapor deposition are redirected from the direction of the flame by differential atmospheric pressure, such as positive pressure provided by a blower or negative pressure provided by a vacuum. This allows, for example, lower surface temperatures of substrates being coated with flame-produced vapors and coating of interior surfaces.Type: GrantFiled: December 21, 2000Date of Patent: April 1, 2008Assignee: n Gimat Co.Inventors: Andrew T. Hunt, Girish N. Deshpande, Tzyy-Jiuan Jan Hwang, Nii Sowa Laye, Miodrag Oljaca, Subramaniam Shanmugham, Shara S. Shoup, Trifon Tomov, William J. Dalzell, Jr., Aimee Poda, Michelle Hendrick

Patent number: 7282238Abstract: A coherent material is formed on a substrate (10) by providing a precursor suspension (14) in which particulates are suspended in a carrier fluid, and directing the precursor suspension (14) at the substrate (10) from a first source (12). Generally contemporaneously with application of the deposited precursor suspension (14) to the surface, hot gases, e.g. hot gases produced by a flame (16), are directed at the substrate (10) from a remote second source (18) to fuse the particulates into the coherent material.Type: GrantFiled: June 27, 2001Date of Patent: October 16, 2007Assignee: nGimat Co.Inventors: Subramaniam Shanmugham, Andrew Tye Hunt, Girish Deshpande, Tzyy-Jiuan Jan Hwang, Erika Moore, Yongdong Jiang

Patent number: 7033637Abstract: Epitatial thin films for use as buffer layers for high temperature superconductors, electrolytes in solid oxide fuel cells (SOFC), gas separation membranes or dielectric material in electronic devices, are disclosed. By using CCVD, CACVD or any other suitable deposition process, epitaxial films having pore-free, ideal grain boundaries, and dense structure can be formed. Several different types of materials are disclosed for use as buffer layers in high temperature superconductors. In addition, the use of epitaxial thin films for electrolytes and electrode formation in SOFCs results in densification for pore-free and ideal gain boundary/interface microstructure. Gas separation membranes for the production of oxygen and hydrogen are also disclosed. These semipermeable membranes are formed by high-quality, dense, gas-tight, pinhole free sub-micro scale layers of mixed-conducting oxides on porous ceramic substrates. Epitaxial thin films as dielectric material in capacitors are also taught herein.Type: GrantFiled: January 12, 2000Date of Patent: April 25, 2006Assignee: MicroCoating Technologies, Inc.Inventors: Andrew Tye Hunt, Girish Deshpande, Wen-Yi Lin, Tzyy-Jiuan Jan

Patent number: 6939576Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.Type: GrantFiled: June 27, 2001Date of Patent: September 6, 2005Assignee: nGimat Co.Inventors: Girish Deshpande, Andrew Tye Hunt, Subramaniam Shanmugham, Eric J. Yurtkuran, Todd Polley, Miodrag Oljara, Tzyy-Jiuan Jan Hwang, Aimee Poda, George Neuman

Patent number: 6869484Abstract: A continuous feed coater for coating a length of substrate with vaporized or sprayed material, is disclosed. A specific example is a roll-to-roll coater which includes two lower supply rollers for supporting two webs of uncoated material, and two upper take-up rollers for supporting the webs after they are coated. A central web-support forms a plenum that acts as a deposition chimney or chamber by bringing the two webs into close proximity to each other to form two large walls of the plenum. The ends of the webs are sealed using side dams to form the chimney with a rectangular cross section such that the vapor cannot exit from the edges of the material. The vaporized coating constituents to be deposited on the rolled material are directed into the deposition plenum from a coating material supply source located at the bottom of the plenum, and are exhausted through the top of the plenum.Type: GrantFiled: September 15, 2001Date of Patent: March 22, 2005Assignee: Shipley Company, L.L.C.Inventors: Andrew T. Hunt, Wayne Neilson, Miodrag Oljaca, Edward J. Reardon, Tzyy-Jiuan Jan Hwang, William D. Danielson, Jr., James D. Huggins, David E. Bane, Ian H. Campbell, Yibin Xue

Publication number: 20030215644Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray.
