Abstract: A process for restoring magnetic recording tape damaged by “Sticky Shed” syndrome cleans magnetic tapes of the Backcoating which is causing their eventual degradation and destruction. The Backcoating is first removed in a multi-step process. A liquid cleaner, such as isopropyl alcohol, is applied to the Backcoating to dissolve it from and clean it off the Mylar Base. Before the liquid cleaner is applied, steps are taken to prevent the cleaner fluid from getting onto the Oxide side of the tape. The chemical cleaning is done as quickly as possible. The second step is to dry clean the Base surface of the tape to remove the remaining solvent and the debris of any remaining Backcoating. Then, the Oxide side of the tape is given a dry, non-chemical cleaning to remove the residue of contamination of the Backcoating which was deposited on the Oxide side of the tape as the result of physical contact with the Backcoating from the storage on the reel of tape.

Abstract: A method for providing a high flux of point of use activated reactive species for semiconductor processing wherein a workpiece is exposed to a gaseous atmosphere containing a transmission gas that is substantially nonattenuating to preselected wavelengths of electromagnetic radiation. A laminar flow of a gaseous constituent is also provided over a substantially planar surface of the workpiece wherein a beam of the electromagnetic radiation is directed into the gaseous atmosphere such that it converges in the laminar flow to provide maximum beam energy in close proximity to the surface of the workpiece, but spaced a finite distance therefrom. The gaseous constituent is dissociated by the beam producing an activated reactive species that reacts with the surface of the workpiece.

Abstract: A cleaning method for removing solid deposits of the oxides of nitrogen, especially dinitrogen pentoxide, from ozone generator tubes and dielectrics is described. The method circulates warm dry gas in the tube section of the generator, warm water in the shell section or both to clean the ozone generator. The oxides are evaporated and evacuated from the system. The method substantially reduces or eliminates the formation of nitric acid on the tubes and dielectrics when the generator is exposed to humidity upon being opened to the atmosphere.

Abstract: Toner xerographically adhered to a material, such as a sheet of paper, may be removed using a solvent-based or solventless approach. The application of ultrasonic tamping, scraping and brushing may aid in removing toner particles. In a solvent-based approach, a solvent may be applied generally or the solvent may be targeted specifically to the toner covered portions of the material to loosen the adhesive securement of the toner to the material. Thereafter, the toner is subjected to a mechanical abrasion using ultrasonic and physical agitation to cause flaking of the toner.

Abstract: A glass workpiece being processed in a vacuum plasma processing chamber is dechucked from a monopolar electrostatic chuck by gradually reducing the chucking voltage during processing while maintaining the voltage high enough to clamp the workpiece. A reverse polarity voltage applied to the chuck at the end of processing assists in dechucking. The workpiece temperature is maintained at a high value at the end of processing to assisting in dechucking. Peak current flowing through the chuck during lifting of the workpiece from the chuck controls the amplitude and/or duration of the reverse polarity voltage during the next dechucking operation.

Abstract: Contaminants are removed from a surface of a substrate by applying a fluid to the surface; lowering the temperature of the fluid to form a solid layer of the fluid and entrap contaminants therein; and applying energy to the layer and/or substrate to cause the layer containing the contaminants to separate from the surface.

Abstract: A cleaning device for a paint brush comprises a hollow nozzle attached to a source of pressurized cleaning solution such as water, solvent, liquefied hot soap or alike. The distal tip of the nozzle is equipped with a poppet valve such that the body of the valve protrudes from the distal tip. The proximal section of the nozzle is adapted to be attached to a source of cleaning solution, that in the most basic configuration being a common tap water valve. When the water valve is opened, the brush is moved towards the nozzle. Upon engaging with the heel or bristles of the brush, the poppet valve moves inwards and opens the flow of water towards the center of the brush allowing washing out any remaining wet and dissolved paint. In another embodiment of the invention, the cleaning device includes a hollow handle attached to a source of pressurized cleaning solution and equipped with one or more nozzles each having a poppet valve.

Abstract: An apparatus and method are provided for removing contaminate particulate matter from substrate surfaces such as semiconductor wafers. The method and apparatus use a material, preferably a liquid curable polymer, which is applied as a sacrificial coating to the surface of a substrate containing contaminate particulate matter thereon. An energy source is used to dislodge the contaminate particulate matter from the surface of the wafer into the sacrificial coating so that the particles are partially or fully encapsulated and suspended in the sacrificial coating. The sacrificial coating is then removed. The coating is preferably formed into a film to facilitate removal of the coating by pulling (stripping) the film providing a cleaner substrate surface.

Abstract: The present invention relates to a method of cleaning a container having an amount of anhydrous ammonia contained therein. The container is first inspected thoroughly for leaks. Heated nitrogen gas is then fed into the container. The heated nitrogen gas may be transported from a nitrogen storage tank to the container via at least one pipe. Liquid nitrogen may be fed into a vaporizer for vaporizing the nitrogen. The liquid nitrogen gas may then be heated via a heater, such as a steamer, to expand the nitrogen gas and ensure that no liquid nitrogen enters the container. The heated nitrogen gas may vaporize any liquid anhydrous ammonia contained therein. Further, the heated nitrogen gas may transport the anhydrous ammonia to a flare for incineration. The heated nitrogen gas may be added any number of times to reduce the concentration of the anhydrous ammonia therein to a desired level. The container may then be steam cleaned and opened to enter and thoroughly clean the inside of the container.

Abstract: An electrode for the alkaline storage battery includes a binding agent containing thermoplastic xylene-formaldehyde resin. Since the thermoplastic xylene-formaldehyde resin is non-aqueous, it is not dissolved into moisture in the air or the alkaline electrolyte within the battery. The electrode is prepared by immersing an active-material-applied or -filled electrode substrate in a solution in which the thermoplastic xylene-formaldehyde resin is dissolved; immersing it in an emulsion of the thermoplastic xylene-formaldehyde resin with an emulsifier; or applying or filling a slurry of the active material with an emulsion of the thermoplastic xylene-formaldehyde resin to or in the electrode substrate. The electrode retains the active material using a binding agent which has excellent adhesion to the active material and imparts high binding capacity of the active materials with one another.
