Patent number: 6656017Abstract: The present invention is a method and apparatus for providing a low-cost and less complex micro-environment for treating a substrate using an impingement cryogenic or steam spray jet. A substrate and fixture is contained within an open-architecture prophylactic or cleaning cell whereupon the substrate and fixture is continuously bathed in a regenerated and re-circulating stream of filtered, inert, dry, heated and ionized atmosphere which bathes both the entire substrate and fixture. This prevents the intrusion of contaminating ambient atmospheres onto critical surfaces. The cleaning cavity is constantly regenerated and re-circulated through the cleaning cell to maintain a majority of the clean atmosphere wherein the clean cavity is pressurized slightly with a small volume of clean dry air or inert gas to prevent the intrusion of ambient atmosphere into the cleaning cell.Type: GrantFiled: April 24, 2002Date of Patent: December 2, 2003Inventor: David P. Jackson

Patent number: 6609960Abstract: A granule dishwashing apparatus with easily removable granule collectors and method of use. The dishwashing apparatus consists primarily of a treatment chamber, a tank, one or more granule collectors and one or more pumping devices. Soiled articles are placed in the treatment chamber to be washed with a mixture consisting of liquid and granules that is sprayed at the articles under high pressure. The mixture falls toward the tank after impacting the articles, passing through the granule collector(s). A liquid only portion is separated from the mixture at some point using the granule collector(s) so that the articles can be rinsed. At any point following a cleaning cycle, the granule collector(s) can be removed to add more granules and to simplify the cleaning of the apparatus. In a multiple collector system, the granule collectors are connected to actuators so that the collectors can be placed in a release mode or a collect mode depending on the function desired.Type: GrantFiled: July 5, 2001Date of Patent: August 26, 2003Assignee: National Conveyor CorporationInventor: Bertil Rogmark

Publication number: 20030134574Abstract: Apparatus for processing a surface of a substrate includes a chamber containing a cavity that has one side that is open, the chamber wall including a lip surrounding the open side of the cavity. Gas ports, disposed within the chamber wall and opening through the lip, emit a pressurized gas so as to create a gas cushion between the lip and the surface when the open side of the cavity is placed adjacent to the surface, thus creating a seal between the cavity and an environment external to the chamber.Type: ApplicationFiled: July 30, 2002Publication date: July 17, 2003Applicant: APPLIED MATERIALS, INC.Inventor: Yoram Uziel

Patent number: 6572457Abstract: Humidity within the workspace of a cryogenic aerosol spray cleaning system is controlled by circulating the workspace atmosphere through a dehumidifier. Advantageously, the need for purging of the workspace atmosphere prior to each cleaning cycle is eliminated. A system and method are thereby provided for cleaning of large workspaces. The system amd method of the invention are especially well-suited, economical, and practical for cleaning operations in which a dry air or inert gas purge of a large volume cleaning chamber would be impractical.Type: GrantFiled: July 31, 2001Date of Patent: June 3, 2003Assignee: Applied Surface TechnologiesInventors: Philip W. DePalma, Robert Sherman

Patent number: 6524394Abstract: The present invention provides a cleaning method in accordance with a degree of soiling and a type of contaminant on a surface to be cleaned of a cleaning target. In the method of cleaning a cleaning target, such as an electrical component, with dry ice, during a process of blasting the dry ice toward the surface to be cleaned from a location where the dry ice is stored, a size of the dry ice is adjusted, so cleaning is performed while a cleaning performance of the dry ice is changed in accordance with the type of soiling or contaminant on the surface to be cleaned.Type: GrantFiled: November 29, 2001Date of Patent: February 25, 2003Assignee: Canon Kabushiki KaishaInventors: Masaki Okazawa, Hideo Iwama
