Rotating Work About An Axis Through Itself During Coating Patents (Class 118/409)
  • Patent number: 9631280
    Abstract: Provided is a method of manufacturing a palladium (Pd) thin film by using an electroless-plating method, the method including: manufacturing a reaction mixture by adding Pd salt and an alkaline pH regulator to an alcohol-water mixed solution; and forming a Pd thin film by loading and stirring the reaction mixture in a substrate. Accordingly, a Pd thin film having a surface enhancement Raman scattering (SERS) effect may be easily manufactured without having to use expensive additional equipment, such as a vacuum device, and in detail, electroless-plating may be performed even on an insulating substrate formed of, for example, glass. In addition, since a size of the Pd thin film manufactured on the substrate may be adjusted, the Pd thin film may be applied to various electrochemical products.

The bottom provides an attachment to a conventional part of the wafer coater and also forms part of the shield. The sides are arranged to extend close to the wafer back at a radius just less than the radius of the wafer. In the improved process, the spindle of the wafer chuck is not rotated at more than 1200 revolutions per minute in any of the wafer spinning operations, and the conventional step of washing the wafer back with a solvent is performed only at the end of the other operations.

    Abstract: In a coater for applying a liquid onto a surface of a moving object, the coater includes a front edge surface, a back edge surface and a slit, wherein the back edge surface has an entrance edge from which the coating liquid is introduced into a gap between the back edge surface and the surface of the object and an exit edge from which the extruded coating liquid leaves the gap with the movement of the object. The back edge surface further is arranged in relation to the object so as to satisfy following two formulas; 1.0 mm.ltoreq.L.ltoreq.30 mm and 1.8.ltoreq.h/h.sub.0 .ltoreq.3 where L is a length of a contour of the back edge surface projected on the surface of the object between the entrance edge and the exit edge; h is a gap distance at the entrance edge; and h is a gap distance at the exit edge.

  • Patent number: 5294257
    Abstract: An apparatus and method for spin coating a substrate with a liquid material which prevents the material from contacting the edge or backside of the substrate or forming an edge bead at the periphery of the substrate is disclosed. A spin chuck is equipped with a conformable elastomer which seals the edge of the substrate and forms a continuous surface with a planar surface of the substrate for the liquid material to flow off the substrate unimpeded during the spin coating process. As the elastomer is resilient, small variations in substrate size and shape are automatically compensated. None of the substrate area is lost to masking and/or removal processes as in the prior art, allowing the entire substrate area to be available for further processing.

  • Patent number: 5059453
    Abstract: Method for coating the inside surface of an elongated metal tubular body which includes placing a plurality of elongated pieces of coating metal into the bore of the tubular body in alignment with the axis thereof, to provide a constant amount of coating metal along the length of the bore. The coating metal melts below the melting point of the tubular body. The bore is freed of oxygen by evacuation or by purging with inert gas. The tubular body and the elongated pieces of coating metal within the bore are then rotated at a high rotational speed sufficient to distribute the elongated pieces against the bore surface while maintaining the constant amount of coating metal along the length of the bore. The rotating tubular body is then heated sufficiently to melt the coating metal pieces and insufficiently to melt the tubular body. Melted coating metal is spread about the bore surface by means of the centrifugal force imposed upon the melted coating metal by the continued rotation of the tubular body.

  • Patent number: 5015505
    Abstract: A method and apparatus for imparting a decorative strip onto the sidewall of a cured tire. The tire is sealed between a pair of chucks and inflated. The sidewall portion of the tire to be decorated is maintained in a flat horizontal posture by the chucks and the inflation pressure. The tire is then rotated while a gun, having a nib is contact with the tire sidewall, dispenses a paint directly onto the tire. A heating element for curing or partially curing the paint is maintained in juxtaposition to the sidewall for heating the paint strip as it passes thereunder.

  • Patent number: 4995331
    Abstract: An apparatus for glazing an article of earthenware or porcelain such as e.g. a plate or the like includes a capstan with a plurality of arms each supporting a workpiece holder for at least one glaze vessel which is rotatable about its axis and tiltable relative to the supporting arm. Before being fed to a glazing station, the article is accurately aligned and imprinted with a mark. A suction unit transfers the article from the centering station to the glaze vessel which is rotated and tilted so as to dip the article in a glaze mass. After surface drying the glaze on the article by initially holding it vertically and then horizontally, the article is transported to a transfer station for placement on a spongy belt which removes excess amount of glaze from the bottom area of the article. The glaze vessel, after being cleared by removing the plate, is refilled with fresh glaze mass in a charging station which is arranged prior to the glazing station.

  • Patent number: 4851263
    Abstract: A method and an apparatus for applying molten wax to one face of a wafer is disclosed. A container having an upwardly facing opening contains the molten wax. The wafer is held substantially horizontally above the opening of the container, with one face of the wafer facing downwardly toward the opening of the container. At least one of the container and the wafer is moved toward the other to bring the opening of the container and underside of the wafer into contact with each other to thereby apply a predetermined amount of molten wax within the container to the underside of the wafer. Preferably, the container is filled with the molten wax such that the molten wax stands up, under surface tension, above a peripheral edge of the opening of the container. Preferably, the wafer is spinned around its central axis in a high speed so that the molten wax applied at the central portion thereof is spread on the entire surface of the wafer and that the extra wax is scattered out of the wafer.
