Abstract: An anisotropic conductive adhesive is provided that includes an epoxy resin, a phenoxy resin, a curing agent, an inorganic filler, and conducting particles as components. The phenoxy resin is controlled to have a glass-transition temperature (Tg) in a range of 66° C. to 100° C., so that the anisotropic conductive adhesive has an excellent fluidity in a mounting process, satisfactory electric conductive/insulation performances, and sufficient adhesiveness. Since the properties of the anisotropic conductive adhesive are almost invariant even if the adhesive is used for a long time under a high-temperature- and high-humidity condition, the anisotropic conductive adhesive can be used for applications where a high reliability is required.

Abstract: Proposed is a zinc oxide-based transparent conductor characterized in having zinc oxide as its primary component, containing an element at 1 to 10 atomic % which has a smaller ion radius than zinc in the zinc oxide and serves as an n-type dopant for the zinc oxide, and containing nitrogen in which the atomicity ratio of nitrogen in relation to the n-type dopant (nitrogen/n-type dopant) is 0.3 to 0.6. In the development of a transparent conductor that does not contain In, which is an expensive raw material with concern of resource depletion, the limit of the conventional development technique known as the single-dopant method is exceeded, a guide to dopant selection as a specific means for realizing the co-doping theory is indicated, and a transparent conductor having low resistivity is provided.

Abstract: The present invention relates to a method to produce highly branched polymers with a polyolefin backbone structure of ethylene and precise control of the nature of the branching. In particular, the distribution of branch length and number of branches can be more precisely controlled via the polymerization method of the present invention. The method comprises using anionic chemistry to make unsaturated polydienes with a well-defined, highly-branched structure, and then hydrogenating these polydienes to form highly branched or dendritic saturated hydrocarbon polymers. Highly branched or dendritic polyethylene, ethylene-propylene copolymer and atactic polypropylene are among the saturated hydrocarbon polymers that can be anionically synthesized via the proper selection of diene monomer type, coupling agent, and hydrogenation conditions.

Abstract: A method of manufacturing carpet provides for an old art dyeing effect. Specifically, acid and cationic dyes are provided in a solution to a carpet tufted with cationic and acid dye fibers. The carpet is preferably tufted in such a way that there is a relative scarcity of one of the cationic and acid dye fibers at a first width. An abundance of the other dye accumulates in higher concentration than in surrounding areas at the first width. This higher concentration tends to diffuse and/or be moved by other mechanisms to the surrounding areas or widths where the dye attaches to appropriate contacts. This creates at least one of the dark band, a fade and/or a old art dye effect at that location. By precisely controlling the carpet fiber location at the upper surface, the dye solution and the dyeing process, fades and other process can be precisely controlled for repeatable performance as has not been experienced in the prior art.
