Patent number: 7141123Abstract: A cleanling apparatus for removing contaminants from the surface of a substrate includes two parts: one which produces an aerosol including frozen particles and directs the aerosol onto the surface of the substrate to remove contaminants from the surface by physical force, and another part in which a fluid including a gaseous reactant is directed onto the surface of the substrate while the surface is irradiated to cause a chemical reaction between the reactant and organic contaminants on the surface, to chemically removing the organic contaminants. In the method of cleaning the substrate, the physical and chemical cleaning processes are carried out in a separate manner from one another so that the frozen particles of the aerosol are not exposed to the effects of the light used in irradiating the surface of the substrate. Therefore, the effectiveness of the aerosol in cleaning the substrate is maximized.Type: GrantFiled: January 20, 2004Date of Patent: November 28, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Moon-hee Lee, Kun-tack Lee, Woo-gwan Shim, Jong-ho Chung

Patent number: 6905553Abstract: The present invention involves a solvent vapor transfer device for holding an absorbent pad, which receives and disperses solvent vapors over a lacquer-based residue on a textile. A solvent is poured or dripped into an absorbent pad portion of the vapor transfer box, from which solvent vapors are released. The solvent vapors pass through the vapor transfer box and concentrate in a vapor chamber over the lacquer-based residue and textile. As the solvent vapors come into continuous contact with the lacquer-based residue, the residue begins to dissolve and soften. Upon sufficient dissolution, minute quantities of the liquid solvent may be applied directly to the partially dissolved residue and quickly suctioned into an extraction vacuum. This process may be repeated as necessary to achieve complete removal of the residue.Type: GrantFiled: March 22, 2004Date of Patent: June 14, 2005Assignee: Harris Research, Inc.Inventors: Shawn T. Rodeback, Edward E. Durrant

Patent number: 6905552Abstract: A cleaning station for a vertical nozzle plate of an ink jet printer includes a cylindrical cleaning roller that has an outer surface, and has a substantially vertical central axis and a substantially vertical rotational axis. The roller is spaced from the nozzle plate to form a cleaning cavity between the roller and the nozzle plate. The roller has a top end above the nozzle plate and a bottom end below the nozzle plate. A drive element is connected to the roller to rotate the roller about its rotation axis. A fluid outlet near the top of the roller directs cleaning fluid onto the outer surface of the roller, and into the cleaning cavity between the roller and the nozzle plate. A fluid reservoir stores cleaning fluid, and a fluid conduit conducts cleaning fluid from the fluid reservoir to the fluid outlet.Type: GrantFiled: December 19, 2002Date of Patent: June 14, 2005Assignee: Xerox CorporationInventors: Werner Fassler, Marcello Fiscella

Patent number: 6893508Abstract: A foot scrubbing device comprising a pedestal with a rough surface pad to step on and four vertical scrubbing posts for scrubbing in between the toes. Beneath the surface pad is a pressurized soap compartment having several channels through which liquid soap may be pumped to the surface of the surface pad via a foot pump. A person may clean his or her foot by placing it on the scrubbing surface so that the toes are placed in between the scrubbing posts. The person then uses his or her other foot to step on the pump pedal, thereby causing liquid soap to move to the surface of the pad where the foot is resting.Type: GrantFiled: March 6, 2001Date of Patent: May 17, 2005Inventor: Ricky Lee Andrews

Patent number: 6883527Abstract: The compressor cleaning system includes a track mounted about the inlet of the compressor. A circumferential position assembly mounts an insertion drive assembly which is driven about the track into selected circumferential positions. The insertion drive assembly carries a manipulator arm assembly mounting at its distal end a cleaning head. By using pairs of control cables, the proximal yaw, pitch and distal yaw sections of the manipulator arm can be moved to weave the cleaning head past the multiple stages of blading to locate the cleaning head adjacent a selected blade. By repeated extension and retraction of the cleaning head relative to the compressor inlet and about the compressor blades, each blade can be cleaned without disassembly of the compressor casing or removal of the rotor.Type: GrantFiled: July 24, 2002Date of Patent: April 26, 2005Assignee: General Electric CompanyInventors: Andrew Joseph Travaly, William Francis Lopes, Kathleen Lynne Bentzel

Patent number: 6884300Abstract: A cleaning sheet has a base sheet, a first polishing layer formed on the base sheet, a porous foamed layer having air bubbles inside formed on the base sheet, and a second polishing layer formed on the foamed layer. The surface of the foamed layer may be flat or preferably porous with the second polishing layer having openings corresponding to those on the porous surface of the foamed layer. For cleaning a probe by using such a cleaning sheet, the tip of the probe is caused to penetrate the surface of the second polishing layer, to pass through the foamed layer and to be pressed against the first polishing layer.Type: GrantFiled: November 19, 2002Date of Patent: April 26, 2005Assignee: Nihon Microcoating Co., Ltd.Inventors: Satoru Sato, Akihiro Sakamoto

Patent number: 6881274Abstract: A test carrier for testing bumped semiconductor components such dice, chip scale packages, BGA devices, and wafers is provided. The test carrier includes a base for retaining one or more components and contact members for making temporary electrical connections with contact balls on the components (e.g., solder balls). The test carrier also includes terminal contacts formed as hard metal balls, as hard metal balls coated with a non-oxidizing metal layer, or as glass, ceramic or plastic members coated with a conductive material. The contact members on the base protect the contact balls on the components from deformation during testing and handling. The terminal contacts on the test carrier are configured for multiple uses in a production environment without deformation. Also provided is a calibration carrier for calibrating semiconductor test systems for bumped components, and a cleaning carrier for cleaning test sockets for bumped components.Type: GrantFiled: September 6, 2002Date of Patent: April 19, 2005Assignee: Micron Technology, Inc.Inventor: David R. Hembree

Patent number: 6878215Abstract: A method of removing a virgin metal oxide coating from the surface of a superalloy gas turbine engine component. The component bearing the applied metal oxide coating is contacted with an aqueous coating-removal solution, typically containing by weight about 10-25% alkali hydroxide, about 1-8% alkanolamine, and about 0.5-5% gluconate salt at a temperature of from about 170° F. (67° C.) to about 210° F. (99° C.), for a time sufficient to remove the metal oxide coating from the superalloy blade by gentle mechanical means. The metal oxide coating can comprise one or more metal oxide layers, such as a chromium oxide layer and an aluminum oxide layer.Type: GrantFiled: May 27, 2004Date of Patent: April 12, 2005Assignee: General Electric CompanyInventor: Robert G.
