Patent number: 6132818Abstract: Prepared is a transcribing plate comprising a glass substrate and a chromium film formed on a surface of the glass substrate. The transcribing plate is disposed on a surface of an object (for example, a glass substrate of a plasma display panel) such that the chromium film faces the surface of the object. The transcribing plate is pressed toward the object, if necessary. A predetermined identification code pattern is drawn on the transcribing plate by a YAG laser beam. The laser beam reaches, through the glass plate, the chromium film to heat it. Chromium vapors generated by the heating are deposited on the surface of the object. This means that the identification code pattern is transcribed on the object surface.Type: GrantFiled: December 29, 1997Date of Patent: October 17, 2000Assignees: Omron Corporation, Miyachi Technos CorporationInventors: Chiharu Tanaka, Tatsuya Nakano, Mitsuo Yonemori, Takeshi Tomita, Masayuki Abe

Patent number: 6066357Abstract: Methods of making a full-color organic light-emitting display are disclosed. The methods include ink-jet printing of fluorescent dopants selected to produce red, green, or blue light emission from designated subpixels of the display.

For an embossed appearance, the ridge of ink is uniformly smooth. For an etched appearance, the ridge of ink is formed with a textured pattern. A sheet having a thin layer of adhesive on one side is pressed onto the substrate over the ridge of ink to adhear the sheet to the substrate and conform the sheet to the ridge to give the appropriate appearance for the design. Alternatively, the sheet may be replaced by a solidified stratum of a metallic-based solution or powder which may be sprayed or electroplated, respectively, onto the substrate.Type: GrantFiled: May 24, 1990Date of Patent: January 21, 1992Inventor: Lawrence J. Longobardi

Patent number: 5034244Abstract: Heat resistant substrates of glass, metal or ceramic are coated by applying onto the substrate a layer of radiation-curable and firable printing ink containing an inorganic ceramic color, curing the layer by exposure to radiation and applying onto the substrate on or adjacent to the radiation curable ink a firable printing ink in the form of a gel containing a precious metal. The coatings may be applied at successive stations of a single automatically operated printing machine, after which the substrates can be fired.Type: GrantFiled: June 5, 1989Date of Patent: July 23, 1991Assignee: Johnson Matthey Public Limited CompanyInventors: Irmin Berrer, Johannes F. Witteveen

Patent number: 5019424Abstract: A decorative container is made by dipping into baths of molten wax, different colors of wax being provided in different baths for successive dipping to provide a multi-colored laminated wax coating on the container. Decorative designs at various locations on the container are formed by carving the wax and turning the laminae outward various degrees, and entirely in use instances, inverting the layers to provide various colors of design.Type: GrantFiled: December 12, 1988Date of Patent: May 28, 1991Assignee: Moonflower Vases CompanyInventor: John Strelnieks

Patent number: 4933218Abstract: A sign with an etched or embossed appearance comprises a transparent substrate on which an extraordinarily thick ridge of viscous ink has been deposited to form a design. For an embossed appearance, the ridge of ink is uniformly smooth. For an etched appearance, the ridge of ink is formed with a textured pattern. A sheet having a thin layer of adhesive on one side is pressed onto the substrate over the ridge of ink to adhere the sheet to the substrate and conform the sheet to the ridge to give the appropriate appearance for the design.Type: GrantFiled: December 28, 1988Date of Patent: June 12, 1990Inventor: Lawrence J. Longobardi

Patent number: 4925705Abstract: A method of printing a number of superimposed or otherwise geometrically related layers on a substrate with exact registration which comprises printing said layers over one or more areas on said substrate so as to overlap the boundary of said one or more areas and then removing the layers outside said areas. The product produced by the method and the intermediate product prior to removal of layers outside the areas can be used for security purposes.Type: GrantFiled: December 23, 1986Date of Patent: May 15, 1990Assignee: Contra Vision LimitedInventor: George R. Hill

Patent number: 4894278Abstract: A decorative mirror having a reflective silver layer deposited on a transparent sheet. A substance which reacts with silver is applied to the silver layer to create randomly distributed areas containing reaction products including non-metallic silver where the visible light reflectance of the mirror is modified or interrupted. In order to manufacture the mirror, a transparent sheet is wetted with a silvering solution to form a reflective silver layer, and while the sheet is still wet with the silvering solution the sheet is contacted with randomly distributed droplets of a solution of a substance which reacts with silver, the two solutions being made up using different solvents. The substance which reacts with silver may be a tin compound in an alcoholic solution, the silvering being effected with an aqueous solution. The silver layer whose reflective properties have been modified may be overcoated with a second silver layer, and the whole protected with further layers, for example of copper and paint.Type: GrantFiled: June 22, 1988Date of Patent: January 16, 1990Assignee: GlaverbelInventors: Albert Servais, Bernard Somerhausen

Patent number: 4835012Abstract: Method and apparatus for applying a curable material having variable curing characteristics to a surface in a defined application cycle which includes the steps of applying only a first slow curing component to the surface of an article at least at the beginning or at the end of an application cycle and applying during the remaining part of the application cycle a mixture of the slow curing component and a curing agent which accelerates the curing of the first component.Type: GrantFiled: December 3, 1986Date of Patent: May 30, 1989Assignee: Gurit-Essex AGInventor: Wolfgang K. Saur

Patent number: 4748054Abstract: A method of providing different colored layers of paint on glass, which method comprises roughening a surface of the glass, applying a first lot of soluble resist to predetermined areas of the roughened glass, then applying a first color paint to the glass, drying the paint, washing off the first lot of soluble resist to expose unpainted roughened glass, drying the glass, applying a second lot of soluble resist on top of some of the first colored paint and on top of some of the exposed unpainted roughened glass, applying a second color paint to the glass, and washing off the second lot of soluble resist to leave the glass with at least one area where the first and the second colors are overlaid, at least one area where the roughened glass only has the first color, and at least one area where the roughened glass only has the second color.Type: GrantFiled: January 13, 1987Date of Patent: May 31, 1988Inventor: Penelope J. Wurr
