Patent number: 7018483Abstract: Thermal cleaning and separation of metal parts is performed by a stator from an electric motor. Windings embedded in an organic, insulating material are placed and heated to 250°–500° C. under controlled conditions in a heating chamber, evaporating organic material and loosened windings. Flue gas is evaporated organic substances conducted through a closed pipe system to a condensator, where organic gases condense. The pipe system is designed so that condensate is conducted-on in the closed pipe system to a partly liquid filled vessel. Contents of this vessel are air and water that flow concurrently with the condensed flue gas as condensate, increasing content of organic material in the vessel and separating condensate from air. Air may be conducted to the oven for renewed absorption of organic material. All organic material evaporated from the heating chamber is collected in the vessel for later disposal in an environmentally correct and secure way.Type: GrantFiled: June 11, 2003Date of Patent: March 28, 2006Assignee: Maskinfabrikken Fornax A/SInventor: Asbjøm Thoustrup

Patent number: 7013821Abstract: An apparatus for cleaning an object floating at the surface of water, e.g., a ship floating on the sea with ease and efficiency by use of a small amount of a cleaning agent is provided. This apparatus comprises a waterproof sheet having an area of covering a region to be cleaned of the object, and a buoyancy bag at its peripheral edge, air supply unit for supplying air into the buoyancy bag of the waterproof sheet laid under the object floating at the surface of water to float the waterproof sheet, so that a pool for accommodating the object is formed by the waterproof sheet, and a spacer for creating a clearance being filled with the cleaning agent between the waterproof sheet and the object accommodated in the pool. According to this apparatus, it is possible to clean the object floating at the surface of water on the spot without landing the object.Type: GrantFiled: November 9, 2001Date of Patent: March 21, 2006Inventor: Jiro Sakurai

Patent number: 6997196Abstract: A dishwasher includes a washing receptacle for items to be cleaned, a pump for liquid, a flow heater for liquid, a device for spraying items to be cleaned, a control device for wash cycles of the spraying device, and a device for providing steam having a separate steam dispenser and unit for producing a jet of steam supplied by the steam dispenser. The steam dispenser and the steam jet unit are disposed in the dishwasher in such a way that the steam jet unit always supplies steam to the same predetermined location in the washing receptacle specifically identified and configured for receiving particular items to be cleaned, e.g. particularly dirty items. An uncontrolled escape of steam from any section of the entire washing receptacle is prevented, thus improving the cleaning result with maximum usage of the steam and without also being dependent on activation of a separate steam washing cycle.Type: GrantFiled: June 28, 2004Date of Patent: February 14, 2006Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventor: Rüdiger Eiermann

Patent number: 6997197Abstract: A surface cleaning apparatus comprising a chamber, and a thermal transfer device. The chamber is capable of holding a semiconductor structure therein. The thermal transfer device is connected to the chamber. The thermal transfer device has a surface disposed inside the chamber for contacting the semiconducting structure and controlling a temperature of the semiconductor structure in contact with the surface. The thermal transfer device has a thermal control module connected to the surface for heating and cooling the surface to thermally cycle the surface. The thermal control module effects a substantially immediate thermal response of the surface when thermally recycling the surface.Type: GrantFiled: December 13, 2002Date of Patent: February 14, 2006Assignee: International Business Machines CorporationInventors: John P. Simons, Kenneth J. McCullough, Wayne M. Moreau, John M. Cotte, Keith R. Pope, Charles J. Taft, Dario L. Goldfarb

Patent number: 6996479Abstract: An apparatus for measuring the water content of a water-containing liquid mixture contained in a tight chemistry tank includes a heating device for controlling the temperature of the liquid mixture to a temperature near the boiling point of the liquid mixture, a cooling medium system disposed at the top of the tight chemistry tank having a cooling medium inlet and a cooling medium outlet, a temperature measurement system for determining the temperature difference between the cooling medium inlet and outlet, and a computing device for calculating the water content of the liquid mixture from the temperature difference. Also provided is a tank for supplying water to the liquid mixture, and a control system for adjusting the amount of water supplied from the tank based upon the water content measured by the measuring apparatus. Also provided is a method for measure the water content.Type: GrantFiled: March 31, 2003Date of Patent: February 7, 2006Assignees: Infineon Technologies AG, Motorola Inc., Infineon Technologies SC300 GmbH & Co., KGInventors: Stefan Ottow, Martin Welzel, Dan Wissel

Patent number: 6974505Abstract: A cleaning tool for cleaning substrates, comprising a circulation conduit through which is circulated a cleaning liquid or gas. The circulation conduit is disposed in fluid communication with an upstream flow chamber and a downstream cleaning chamber, the cross-sectional area of which cleaning chamber is less than the cross-sectional area of the flow chamber. In use, the cleaning chamber receives a wafer substrate for cleaning of particles or removal of polymer films from the substrate. The smaller cross-sectional area of the cleaning chamber accelerates the flow of a cleaning fluid flowing through the cleaning chamber from the flow chamber. The rapidly-flowing cleaning fluid removes the particles and/or films from the substrate while preventing dropping of the removed particles or re-deposition of the film back onto the substrate. A particle filter may be provided in the circulation conduit downstream of the cleaning chamber for removing the particles.Type: GrantFiled: October 16, 2002Date of Patent: December 13, 2005Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Hsin-Ching Shih, Chun-Li Chou, Ming-Hong Hsieh, Hong-J.
