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

Patent number: 6878203Abstract: A resin application station has processing units for heating dynamo-electric machine components. In one or more of the processing units batches of components are placed in fixtures on vertically rotating support plates. The vertically rotating support plates are mounted in cabinets. Heated air is circulated in the cabinets to control the ambient temperature. The components travel through regions of the controlled temperature ambient as the support plates rotate and are heated to process temperatures. Intermittent rotation of a support plate in a unit allows loading and unloading of an individual component from the unit while the support plate is stationary. The support plate rotations in all the units are synchronized to increase the station throughput.Type: GrantFiled: February 11, 2002Date of Patent: April 12, 2005Assignee: Axis USA, Inc.Inventors: Raffaele Becherucci, Gianfranco Stratico

Patent number: 6875462Abstract: A method for making a field emission cold cathode for use in vacuum tubes. A carbon velvet material is coated with a low work function cesiated salt and bonded to a cathode surface. Alternatively, the carbon velvet material is bonded to the cathode surface before being coated with the cesiated salt. The coating may be applied by spraying the carbon velvet material with a cesiated salt solution, or by dipping the material into a crucible of molten cesiated salt. This abstract is provided to comply with the rules requiring an abstract, and is intended to allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning the claims.Type: GrantFiled: January 26, 2004Date of Patent: April 5, 2005Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Donald A. Shiffler, Jr.

Patent number: 6875466Abstract: The wafer coated with the resist is deliberately placed in the vapor before being transferred to an aligner that exposes the resist on the wafer, the vapor, for example, the moisture, uniformly adheres onto the resist on the wafer. As a result, the substrate can uniformly be exposed in the following exposing process, and the uniformity of the line width and the like can be improved.Type: GrantFiled: November 21, 2002Date of Patent: April 5, 2005Assignee: Tokyo Electron LimitedInventors: Hidefumi Matsui, Junichi Kitano

Publication number: 20040224158Abstract: A process of coating a refractory turbine part with a protective coating which is ultimately diffusion bonded to the part. A slurry coating material is prepared from a mixture of a silicon alkyd paint and suspended particles of an aluminum or aluminum alloy powder. Parts may be dipped in the slurry and subsequently be heat treated in selected atmospheres and temperatures to diffuse the coating into the surface of the part.Type: ApplicationFiled: June 15, 2004Publication date: November 11, 2004Inventors: Vladimir Moravek, Paul Lowden, Joseph Liburdi

Publication number: 20040214991Abstract: A method for manufacturing a composite collagen film. The method includes providing a collagen film and dipping the collagen film in a solution of collagen and glycosaminoglycans (GAGs). The method further includes sequentially performing a freezing process, a vacuum freezing drying process, a condensing process, and a drying process. Finally, the method comprises using a cross-linking agent for making the collagen film cross link with the collagen and GAGs in the solution so as to produce a composite collagen film.Type: ApplicationFiled: April 22, 2003Publication date: October 28, 2004Inventors: Jo-Yi Hsiao, Hsiao-Cheng Yen

Publication number: 20040202790Abstract: The surface temperature of a coating film after being applied and dried is quickly increased to a thermal treatment temperature in the range of from 60 to 100° C. in a heating zone of a thermal treatment device. Then, the surface temperature of the coating film having been heat-treated is kept at the thermal treatment temperature for a time period in the range of 1 to 60 seconds in a thermal retaining zone. Then, the surface temperature of the coating film having been thermal-retaining-treated is forcefully decreased from the thermal treatment temperature to near a room temperature in a cooling zone. By the three-phase process in the thermal treatment device, the surface of the emulsion layer is prevented from stripping during processing such as slitting, a photothermographic material excellent in photographing performance can be obtained, and productivity is improved.Type: ApplicationFiled: April 8, 2003Publication date: October 14, 2004Applicant: FUJI PHOTO FILM CO., LTD.Inventor: Kenichi Ogata
