  • Identification card printer
    Patent number: 6241332
    Abstract: Information is printed onto an identification card using an ink jet printer. The ink jet printer includes a tray which moves the card in a first direction and a print head which moves relative to the card in a second direction. An ink receiving surface may be deposited onto the card prior to ink jet printing. A magnetic recording head is optionally included in the printer whereby information may be magnetically recorded onto the card.
    Type: Grant
    Filed: October 20, 1999
    Date of Patent: June 5, 2001
    Assignee: Fargo Electronics, Inc.
    Inventors: Robert P. Cummins, Darren W. Haas, Erick Hagstrom, Matthew K. Dunham, Bradley A. Paulson
  • Ink jet printable surface
    Patent number: 6051306
    Abstract: An ink jet receiving surface includes a first hydrophilic polymer containing a hydroxyl group and a second hydrophilic polymer containing an amid, amine, imide, or imine group. A multicarboxylic acid or derivative thereof is provided which polymerizes the second hydrophilic polymer around the first hydrophilic polymer. Optionally pigment and binder are included in the surface.

  • Method of making patterned metal oxide films comprising a sol-gel of metal oxide and a photoactive compound
    Patent number: 5100764
    Abstract: A method of making patterned metal oxide films on microelectronic wafer substrates. They are prepared by making a sol-gel of a metal oxide in combination with an ultraviolet light sensitive photo-active compound. The sol-gel is applied to a silicon wafer substrate, and the wafer subjected to a predetermined pattern of ultraviolet light to cause the photo-active compound to respond to the ultraviolet light. The wafer is thereafter aqueous alkali metal hydroxide washed to wash away the portions of the metal alkoxide film which have been exposed to UV light.

  • Use of sol-gel derived tantalum oxide as a protective coating for etching silicon
    Patent number: 5011568
    Abstract: Thin film resonators are prepared by an improved process involving coating a patterned wafer with a sol-gel derived tantalum (V) oxide passivating film so that the circuitry can be protected from etching chemicals during the etching of vias through the back of the silicon wafer.
