  • Patent number: 7811667
    Abstract: A carbon nanotube (CNT) film having a transformed substrate structure and a manufacturing method thereof. The CNT film includes a transparent substrate, a plurality of three-dimensional (3D) structures formed distant from each other on the transparent substrate, and carbon nanotubes (CNTs) deposited on the transparent substrate where the plurality of 3D structures is not formed. The method includes forming a plurality of 3D structures distant from each other on a transparent substrate, and depositing a CNT solution on the substrate with the plurality of 3D structures formed thereon, wherein the CNT solution is deposited into a portion of the transparent substrate where the 3D structures are not formed. Thus, the deposition mechanism of the CNT solution is controlled to thereby increase the transparency of the CNT film and the electrical conductivity of an electrode including the CNT film.

  • Patent number: 7595105
    Abstract: The invention relates to composite articles comprising a substrate and additional layers on the substrate. According to one example, the layers are selected so that the difference in the coefficient of thermal expansion (CTE) between the substrate and a first layer on one side of the substrate is substantially equal to the CTE difference between the substrate and a second layer on the other side of the substrate. The stress caused by the CTE difference and/or shrinkage on one side of the substrate during heating or cooling is balanced by the stress caused by the CTE difference on the other side of the substrate during heating or cooling. Such stress balancing can reduce or minimize curling of the substrate.

  • Patent number: 5681671
    Abstract: Electro-conductive oxides showing excellent electro-conductivity, electrodes using the electro-conductive oxide and methods for manufacturing the same are described. The electro-conductive oxides are represented by the general formula: M(1).sub.x M(2).sub.y In.sub.z O.sub.(x+3y/2+3z/2)-d. The above electro-conductive oxides show not only excellent electro-conductivity but also excellent transparency all over the visible region and therefore they are particularly useful as, for example, electrodes for liquid crystal displays, EL displays and solar cells, which require light transmission.

    Abstract: A retro-reflective vision control panel which includes an opaque sheet material coated with retro-reflective light reflecting particles and a dark opaque color on the reverse side thereof, and an image formed over top the retro-reflective particles using colored light permeable translucent inks or films to form an image thereon. The opaque sheet and image have a plurality of perforations spaced thereover such that when the light level on the image side of said panel is slightly less than, equal to, or greater than that on the other side, an observer on the image side clearly sees the image while an observer on the other side sees through the panel without seeing any trace whatsoever of the image or design.

  • Patent number: 5609938
    Abstract: One or more panels define a support for an image layer and a relatively dark layer. Holes extend through the panel and the layer. The holes allow viewing through the panels in one direction without seeing the image, yet the image can be viewed by looking at the panel assembly from the opposite direction. Thus, the image is suitable as an advertising medium as applied to the transparent windows of buildings, vehicles and the like. A person sitting in a building or in a vehicle cannot see the image on a window by looking outwardly through the window. Looking in the opposite direction, from outside to inside the vehicle, a person will see the image through the assembly of panels.

  • Patent number: 5520989
    Abstract: A sheet of writing paper which is white, but which has been colored, or tinted to a pastel color by printing on its surface with a strippable or chemically removable ink. The surface printing with ink allows the paper to have a desirable tinted color, but allows the color to be easily removed so that the paper can be relatively easily recycled and reused without the normal problems associated with recycling of vat-dyed tinted papers. The surface printing can be accomplished by printing a random spotted pattern on the paper to provide for the perception of tinting. The invention allows the printed pattern to have a random-toned effect or allows the visual incorporation of words or symbols which would very subtly appear, macroscopically, in the tinting pattern.

  • Patent number: 5407718
    Abstract: A label sheet assembly for transparent paper labels has a substantially transparent paper label sheet with a substantially transparent, pressure sensitive adhesive coating. Labels are die cut out of the paper label sheet. The paper label sheet is mounted on a backing sheet, which has a release coating to allow removal of the labels. The pressure sensitive adhesive may be stable in the presence of temperatures up to 200 degrees Fahrenheit so that the labels may be printed in a laser printer. The label sheet assembly may be printed in its entirety by an ink jet printer or xerographic printer with a resulting high print quality. A method for printing transparent label sheet assemblies comprises forming double thickness label sheet assemblies, creating a paper supply, feeding label sheet assemblies from the paper supply through xerographic and ink jet printers, removing labels from a backing sheet, and applying the labels to products to be labeled.
