  • Glare-resistant touch panel
    Patent number: 6572941
    Abstract: A touch panel is constructed of a top sheet member having a resistive membrane on its inner surface and a base sheet member having a resistive membrane on its inner surface, the top and base sheet members facing each other with dot spacers being located in between. The top sheet member is formed by laminating a PET film, a polarizing film, a ¼&lgr; retardation film, and a light isotropic film in this order from its outer surface. The PET film has a thermal expansion coefficient lower than the other films underneath, such as the polarizing film. Accordingly, the PET film serves to keep the other films of the top sheet member from bulging outward when the temperature rises.

  • Particle lock joint
    Patent number: 6572962
    Abstract: The invention comprises a joint formed by mechanical interaction of particles with the parts to be joined. The particles engage an interface surface of each part, creating a high friction condition that prevents further relative movement of the parts once they are assembled. The particles have a substantially flat or flake-like morphology. The surface of each particle is rough to enhance mechanical engagement with each interface surface. The flake-like shape prevents the particle from penetrating an elastomeric part, which would render the particle ineffective in the bonding process.

  • Multilayered polymer films with recyclable or recycled layers
    Patent number: 6569515
    Abstract: A multilayered polymer film is formed with a stack of one or more first optical layers, one or more second optical layers, and one or more non-optical layers. These optical and non-optical layers are typically made using polymer materials, such as polyesters. In one embodiment, the non-optical layers are made from a polyester having a composition which corresponds to the average molar composition of the combination of all of the first and second optical layers. Using this formulation, scrap material from the manufacture of multilayered polymer films may be used to generate the non-optical layers in subsequent films. Alternatively, the non-optical layers of a multilayered polymer film are made using scrap material from prior-manufactured multilayered polymer films with the optional addition of other polymer material which may be either new or recycled.

  • Non-exuding optically brightened polyolefin blends
    Patent number: 6565987
    Abstract: Optical brighteners are widely used for decreasing the apparent yellowness of polymeric materials. Polyethylene, as a coating film for photographic paper has presented unique problems because of its general lack of compatibility with conventional, large, fluorescent brightener molecules. The present invention provides a solution to this problem by incorporating into the polyethylene an optical brightener compatibilizing amount of a second polyolefin having alkyl groups pendant from the polymer backbone which serves to reduce the exudation of the optical brightener in articles or substrates comprised of or coated with such compositions.
