    Abstract: First, an object and an applicator for supplying a solution prepared by dissolving an oil repellent in a volatile solvent are arranged with an end of the applicator and the object substantially away from each other. Then, the solution is supplied from a solution reservoir for storing the solution to the applicator through a solution passage connecting the solution reservoir and the applicator to each other, and thereafter the solution is made to ooze from the end of the applicator while one of the object and the applicator is moved relative to the other. A space between the object and the end of the applicator is filled with the solution and a distance between the object and the end of the applicator is determined to allow the solution to be held in the space by surface tension.

    Abstract: A system for cleaning semiconductor lithography tools provides for cycling a polished-side down semiconductor wafer through the lithography tool using conventional automated robotics for loading and unloading the wafer from a vacuum chuck of the lithography tool. The vacuum chuck may provide a continuous clamping vacuum feature and may include a vacuum ring that surround the periphery of the vacuum chuck. The chuck and vacuum ring may advantageously be formed of a high accuracy ceramic or plastic such as ZeroDur ceramic. The polished side of the semiconductor wafer includes grooves in a polished surface and which extend inwardly from a peripheral edge of the wafer, the grooves provide gaps between the wafer and chuck allowing the wafer to be released by a slow loss of vacuum-pressure through the gaps. The pristine clean polished surface of the wafer getters contaminating particles from the chuck.

  • Patent number: 7204890
    Abstract: Many prior art processes for cleaning predominantly organic hard surfaces have been found to be considerably less effective in removing very fine particles on such surfaces than are the best cleaners for metallic surfaces. However, it has been found, and forms the basis of this invention, that fine particles can be removed effectively from organic surfaces by an indirect process of first forming a thin solid coating over the surface and then removing the solid coating, into which the fine particles that formerly contaminated the surface to be cleaned have presumably become incorporated. Substantially hydrolyzed poly(vinyl acetate) has been found particularly useful for forming the thin solid coating when this coating is to be removed by treatment with an acidic aqueous solution; acrylate polymers are preferred if the solid coating is to be removed by an alkaline aqueous solution.

Therefore, the rest of the wipes are not exposed to the exterior, only the wipe that is in use. User may manually handle the device, expose the wipe for cleaning the desired surface, and thereafter user may pull the wipe and detach it from the device by tearing it off with a cutter slot of the device.

  • Patent number: 7189289
    Abstract: Disclosed is a cleaning agent for heater tubes, which is capable of eliminating deposits such as soot particulates in tubes installed in industrial heaters that typically use oil, coal or gas. The cleaning agent of the present invention is prepared by formulating a chemical composition comprising ammonium nitrate into pellets. Also, the present invention discloses a method of cleaning heater tubes using the cleaning agent. When being utilized for cleaning the heater tubes, the cleaning agent can improve mechanical and chemical cleaning effects, thus shortening of working time and reducing a required amount of the chemical composition, as well as preventing rapid evaporation of the chemical composition, thus increasing cleaning effect. In addition, the cleaning agent can eliminate the cementing effect of sulfur oxides or vanadic oxides in the heater tubes and thus control stably emission of NOx, by selectively containing other additives including magnesium and urea.

  • Patent number: 7185663
    Abstract: Methods and compositions for on-line cleaning of internal surfaces of selected sections of a hydrocarbon fuel burning gas turbine and associated heat recovery equipment, during operation. Cleaning solutions containing graphite and/or molybdenum-based particles and oil soluble corrosion inhibitors, aromatic solvents, and surfactants are selectively introduced directly into the combustion chamber (combustor) of the gas turbine, into the fuel stream, water washing system, or the combustion air system (hot gas path). The cleaning process dislodges unwanted ash deposit buildup and, thereby restores the gas turbine to rated power. When introduced into the compressor section, the particles impinge on the metal surfaces, cleaning them prior to entering the hot gas section where the process may be repeated. They may also be carried through the exhaust to additionally clean attendant heat recovery equipment, if present.

  • Patent number: 7182820
    Abstract: Methods and apparatus for cleaning hearing aid devices are disclosed. Drying is facilitated in hearing instruments through a novel combination of heater and desiccant in an essentially closed system. Greater efficiency is obtained by minimizing the volume of gas, e.g., air, requiring moisture extraction.

  • Patent number: 7169235
    Abstract: A method is suitable for cleaning substrates, after polishing, that require a high degree of cleanliness, such as semiconductor wafers, glass substrates, or liquid crystal displays. The method includes polishing a substrate using an abrasive liquid containing abrasive particles, and cleaning a polished surface of the substrate by supplying a cleaning liquid having substantially the same pH as the abrasive liquid or similar pH to the abrasive liquid so that a pH of the abrasive liquid attached to the polished surface of the substrate is not rapidly changed.

  • Patent number: 7156926
    Abstract: A method of removing iron oxide scale from processed sheet metal comprises the steps of: providing a surface conditioning apparatus; and conditioning a surface of the processed sheet metal with the surface conditioning apparatus. In general, the iron oxide scale generally comprises three layers prior to surface conditioning: a wustite layer, a magnetite layer, and a hematite layer. The wustite layer is bonded to a base metal substrate of the processed sheet metal. The magnetite layer is bonded to the wustite layer, and the hematite layer is bonded to the magnetite layer. The surface conditioning apparatus has at least one surface conditioning member. The step of conditioning the surface of the processed sheet metal includes bringing the at least one surface conditioning member into engagement with the surface of the sheet metal.

  • Patent number: 7153371
    Abstract: An extraction cleaning machine comprising dispensing and recovery systems, the dispensing system including a system for generating heat with an exothermic reaction upon activation for heating the cleaning solution prior to dispensing of the cleaning solution onto a surface. The cleaning solution dispensing system comprises a cleaning solution reservoir to which the heat of the exothermic reaction can be added and a dispenser. The heat of the exothermic reaction can also be added in line to the cleaning solution between the cleaning solution reservoir and the dispenser. The recovery system includes a suction nozzle, a recovery tank and a vacuum source for drawing recovered liquid from the suction nozzle into the recovery tank. A method of cleaning a surface comprises the steps of heating a cleaning solution by an exothermic chemical reaction, applying the cleaning solution to the surface and recovering the cleaning solution from the surface.
