Publication number: 20110073138Abstract: A cleaning system that utilizes an organic cleaning solvent and pressurized fluid solvent is disclosed. The system has no conventional evaporative hot air drying cycle. Instead, the system utilizes the solubility of the organic solvent in pressurized fluid solvent as well as the physical properties of pressurized fluid solvent. After an organic solvent cleaning cycle, the solvent is extracted from the textiles at high speed in a rotating drum in the same way conventional solvents are extracted from textiles in conventional evaporative hot air dry cleaning machines. Instead of proceeding to a conventional drying cycle, the extracted textiles are then immersed in pressurized fluid solvent to extract the residual organic solvent from the textiles. This is possible because the organic solvent is soluble in pressurized fluid solvent. After the textiles are immersed in pressurized fluid solvent, pressurized fluid solvent is pumped from the drum.Type: ApplicationFiled: December 9, 2010Publication date: March 31, 2011Applicant: EMINENT TECHNOLOGIES LLCInventors: James E.

Publication number: 20100173477Abstract: A cause of deteriorating the hydrogen termination on the surface of a wafer is found to be water adsorbed on the surface. By exposing the wafer to an inert gas atmosphere containing an H2 gas so as to suppress the oxidation reaction due to the water, it is possible to improve the hydrogen termination on the wafer surface.Type: ApplicationFiled: September 13, 2005Publication date: July 8, 2010Inventors: Tadahiro Ohmi, Akinobu Teramoto, Hiroshi Akahori

Publication number: 20100083991Abstract: The present invention describes a drying system for a dishwasher having a washing tub (2). The drying system comprises: a first fan (3) for propelling a first air stream through the washing tub (2) to an air transporting space (9) situated in the dishwasher outside the washing tub (2), wherein the first air stream is propelled in such a way that humidity in the washing tub (2) is absorbed by the first air stream and propelled to the air transporting space (9); and a second fan (4) for propelling a second air stream received from an area outside the dishwasher to the air transporting space (9). The drying system is further arranged such that the first and the second air streams are mixed in the air transporting space (9), and in that the mixed air stream is propelled to an exhaust opening (10) leading out from the dishwasher. Thereby, an efficient drying process can be achieved wherein air leaving the dishwasher has an appropriate temperature and humidity.Type: ApplicationFiled: February 20, 2008Publication date: April 8, 2010Applicant: ELECTROLUX HOME PRODUCTS CORPORATION N.V.Inventor: Anders Tolf

Patent number: 7678199Abstract: A method is provided for reducing the amount of film fragments discharged into a processing liquid circulation system during removal of films from wafers, thereby reducing the frequency of filter cleaning or filter replacement. The method includes exposing a wafer containing a film formed thereon in a process chamber of a substrate processing system to a processing liquid, where the wafer is not rotated or is rotated at a first speed and the processing liquid is discharged from the process chamber to a processing liquid circulation system. Subsequently, exposure of the wafer to the processing liquid is discontinued and the wafer is rotated at a second speed greater than the first speed to centrifugally remove fragments of the film from the wafer. Next, the wafer is exposed to the same or a different processing liquid and the processing liquid is discharged from the process chamber to a processing liquid drain.Type: GrantFiled: September 6, 2006Date of Patent: March 16, 2010Assignee: Tokyo Electron LimitedInventors: Shogo Mizota, Minami Teruomi, Kenji Yokomizo, Taira Masaki
