  • Patent number: 6344272
    Abstract: The present invention is for particulate compositions and methods for producing them that can absorb or scatter electromagnetic radiation. The particles are homogeneous in size and are comprised of a nonconducting inner layer that is surrounded by an electrically conducting material. The ratio of the thickness of the nonconducting layer to the thickness of the outer conducting shell is determinative of the wavelength of maximum absorbance or scattering of the particle. Unique solution phase methods for synthesizing the particles involve linking clusters of the conducting atoms, ions, or molecules to the nonconducting inner layer by linear molecules. This step can be followed by growth of the metal onto the clusters to form a coherent conducting shell that encapsulates the core.

  • Patent number: 6337149
    Abstract: A lanthanum aluminate (LaAlO3) substrate on which thin films of layered perovskite copper oxide superconductors are formed. Lanthanum aluminate, with a pseudo-cubic perovskite crystal structure, has a crystal structure and lattice constant that closely match the crystal structures and lattice constants of the layered perovskite superconductors. Therefore, it promotes epitaxial film growth of the superconductors, with the crystals being oriented in the proper direction for good superconductive electrical properties, such as a high critical current density. In addition, LaAlO3 has good high frequency properties, such as a low loss tangent and low dielectric constant at superconductive temperatures. Finally, lanthanum aluminate does not significantly interact with the superconductors. Lanthanum aluminate can also be used to form thin insulating films between the superconductor layers, which allows for the fabrication of a wide variety of superconductor circuit elements.

  • Patent number: 6329041
    Abstract: The present invention relates to a hard coat film used for various types of displays, wherein cracking and peeling of the hard coat layer is prevented, hardness reduction of the hard coat film is suppressed and the pencil hardness of the hard coat film is in the range of 4H-8H. The hard coat film includes a buffer layer (2) with a thickness of 3-50 &mgr;m, formed on at least one side of a plastic base film (1), which has a buffer function against deformation of the hard coat layer in response to deformation of the plastic base film (1), and a hard coat layer (3) with a thickness of 3-15 &mgr;m additionally formed over the buffer layer. The hard coat film (9) is designed so that the pencil hardness of the plastic base film (1), the pencil hardness of the buffer layer and the pencil hardness of the hard coat layer increase in that order.

  • Patent number: 6294256
    Abstract: A composition of matter for use as dielectric shield in an electric power cable having insulation of XLPE, EPR or EPDM comprises: a base polymer which is a copolymer of ethylene with a mono-unsaturated ester; conductive carbon black in an amount to give the composition an electrical resistivity below 500 Am; and as an adhesion-adjusting additive, 1-20% by weight of the base polymer of a copolymer which consists essentially of ethylene and a comonomer having in its molecule at least one carbon-oxygen dipole, said copolymer having a molecular weight less than 20,000 Daltons but a melting point higher than 30° C. This new class of additive permits use of EVA's with lower vinyl acetate content than prior art additives and so enables the composition to have less rubbery physical properties.

  • Patent number: 6265065
    Abstract: A corrosion-resistant joint for use on concrete reinforcing rods and a method to create such a joint are provided. Metal reinforcing bars are typically coated to resist corrosion. However, cutting, welding and mechanical joining of these rods disturbs the anticorrosion coating and introduces sites of potential corrosion. The corrosion-resistant joint comprises a first rod joined to a second rod with a two-layered plastic sleeve slid over the joint. A corrosion-resistant joint is created by heating the joint, causing the inner layer of the sleeve to liquefy while the outer layer shrinks, forcing the liquid inner layer into the intricacies of the joint creating a corrosion barrier. Ends of rods and regions of a rod from which the anticorrosion coating has been accidentally removed can also be protected from corrosion.

  • Patent number: 6254969
    Abstract: A shelf life indicating structure including a substrate printed with an oxygen sensitive ink in combination with an oxygen scavenging layer is disclosed. The oxygen scavenging layer prevents oxygen reaching the substrate for a predetermined interval. Once the finite oxygen scavenging capability of the layer is exhausted, oxygen reaches the substrate, thereby activating a visible indication such as a color change, in the ink. The substrate and layer may be formed into a patch or label for a package, and covered with an oxygen impermeable layer, such as a strip of aluminum foil which can be peeled off to initiate a shelf life indication structure. A method associated with the shelf life indicating structure is also provided.
