  • Patent number: 6673390
    Abstract: A method for manufacturing a touch screen linearization pattern which is necessary for a five wire resistive type or current sensing type touch screen, and directly affects the accuracy, production price, and border area size of the touch screen, includes the steps of printing a linearization pattern on the border area of a conductive glass surface with a selected ink. The ink is made by blending highly conductive silver powder between about 59% to 62% in weight and carbon powder between about 14% to 16% in a contact agent solvent between about 24% to 25% in weight. The touch screen thus formed has a resistance value ratio of about ten between the square surface of the glass layer and the two ends of the linearization pattern.

  • Patent number: 6663143
    Abstract: An artwork is made on a surface of a matrix or plate with acrylic paint and then allowing the paint to dry. A layer of a backing material adhesive, such as an acrylic gel, is next applied to the acrylic layer and a backing material (such as paper or cloth) is placed upon the gel, and the wet gel is then allowed to dry. The dry artwork is then removed from the matrix. The invention allows the inclusion within a single image of other media (wet or dry), such as paper, fabric, dry acrylic elements, watercolor, waterbase crayons and pencils, felt pens, waterbase inks, water mixable oil paints, oil pastels and oil paint sticks because of the bonding abilities of acrylics.

    Abstract: This is a fabrication process for Y-branch nickel/zinc-indiffused polarization splitters on lithium niobate. The fabrication technology needs only two nickel/zinc indiffusions; one at a high temperature and the other at a lower temperature. Nickel/zinc-indiffused waveguides can support single-ordinary, single-extraordinary, and random polarization waves depending on the fabrication process parameters. High extinction ratios can be achieved due to the inherent single-polarization of the waveguides. The splitting ratios of the TE and TM modes are sufficiently high for practical applications.

    Abstract: 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.

    Abstract: A method is described for the nucleation controlled deposition of ferroelectric thin films by chemical vapor deposition in a novel processing sequence wherein a higher density of bismuth nucleation sites is achieved either by the use of a substrate member which has been treated in a manner to yield a controllably and reproducible rough surface on which SBT films with excellent properties may be produced or by using a chemically modified substrate surface upon which surface chemical properties are modified. Typical techniques for achieving surface roughening include reactive ion etching, inert ion milling and chemical mechanical polishing, each of which may be used to delineate patterned bottom electrodes. The chemical properties of the substrate may be modified by alloy deposition, deposition of seed layers which are then partially or completely in-diffused ion implantation with or without heat treatment and changing the chemistry of the surface by a pre-exposure to chemical agents prior to deposition.

    Abstract: A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellent material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellent material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.

  • Patent number: 5891520
    Abstract: A method for decorating and/or labelling glass articles and like ceramic ware by screen printing. The present method comprises the steps of (a) treating a glass article or the like with a silane adhesion promoter; and (b) applying a non-ceramic screen ink directly onto the silane-treated glass article by screen printing. The non-ceramic screen ink is preferably a heat-set ink which includes an organic resinous binder, a non-heavy metal colorant and a vaporizable solvent system. Examples of the binder include, but are not limited to, one or more of polyamide, polyester, polyester-vinyl, acrylic, vinyl and acrylic-vinyl resins. Examples of the non-heavy metal colorant include titanium dioxide and organic colorants (e.g., insoluble derivatives of organic dyes). The non-ceramic screen ink may additionally comprise one or more rheology-adjusting agents for making the ink well-suited for screen printing and may additionally include other additives of the type commonly found in screen or other printing inks.

  • Patent number: 5872655
    Abstract: A process suitable for forming multi-layer (up to at least several hundred layers) monotonic/linear variable/wedge filter coatings on a single substrate surface and for forming monolithic filter assemblies which incorporate such filters, is disclosed along with the designs for such filters. The monolithic process uses radially variable filter fabrication techniques in combination with ion-assisted deposition to form stress controlled, radially variable filter coatings of the desired varied optical profile, preferably using high and low index materials stich as tantala and silica. Stress is minimized by balancing the amount of ion assist and the coating rate. Slices are cut radially from the substrate to form quasi-linear variable filters. Other coatings such as, but not limited to, a wide band hot mirror can be formed on the opposite surface of the substrate from the radially variable LVF method.

  • Patent number: 5800860
    Abstract: A novel planar waveguide structure has been constructed by sintering substantially pure SiO.sub.2 layers in a He.sub.2 /BCl.sub.3 atmosphere. This results in the generation of a liquid phase of substantially lower viscosity than that of the deposited silica by itself. Since viscous sintering is enhanced by the presence of this liquid, consolidation occurs at lower temperature, e.g. 1000.degree.-1100.degree. C., than those used in the prior art, e.g. 1350.degree.-1500.degree. C. Much of the B.sub.2 O.sub.3 remains unreacted with the silica particles it helps to sinter, acting like a flux to bring about consolidation. This remaining B.sub.2 O.sub.3 is removed at the conclusion of the consolidation procedure by steam treatment at temperatures of 900.degree.-1100.degree. C. Some boron is incorporated into the silica layer, changing its CTE without substantially increasing its index.

  • Patent number: 5741557
    Abstract: A method for forming a desired pattern of a material of conductive or non-conductive type on a variety of substrates. It is based on the use of a pen which essentially consists of a refractory tip wetted with the material in the molten state. The pen preferably consists of a pointed tungsten tip attached to the top of a V-shaped tungsten heater, forming a heater assembly. The tip and the heater top portion are roughened at the vicinity of the welding point. In turn, the ends of the V-shaped heater are welded to the pins of a 3-lead TO-5 package base. The pen is incorporated in an apparatus adapted to the direct writing technique. To that end, the pen is attached to a supporting device capable of movements in the X, Y and Z directions, while the substrate is placed on an X-Y stage for adequate X, Y and Z relative movements therebetween. The two pins of the pen are connected to a power supply to resistively heat the heater.
