  • Patent number: 7172958
    Abstract: A high-frequency wiring structure includes a microstrip line having a ground conductor, a dielectric disposed on the ground conductor, and a transmission conductor that is at least partially disposed in the dielectric. The transmission conductor is defined by a flat bottom parallel to the ground conductor, a pair of flat sides that are perpendicular to the ground conductor and are positioned on both sides of the flat bottom in the wiring width direction, and curved parts that continuously join the flat bottom and the pair of flat sides. The curved parts have a radius of curvature within the range of 5% to 50% of the thickness of the transmission conductor.

  • Publication number: 20050218491
    Abstract: The present invention provides a circuit component module having high precision, reliability, and low manufacturing costs, and a method of manufacturing the same. A circuit component module includes an electronic component, wiring lines formed in a predetermined pattern, and a resin layer for covering some of the wiring lines and the electronic component. The wiring lines are made of, for example, Cu, and are composed of first wiring lines and second wiring lines opposite to the first wiring lines with the resin layer interposed therebetween. The first wiring lines and the second wiring lines are electrically connected to the electronic component at predetermined positions.

  • Patent number: 5486403
    Abstract: An alignment layer for use in liquid crystals including a macromolecular material deposited on a glass substrate, the macromolecular material composed of main molecular chains which are, on the average, aligned in a first direction. A series of parallel microgrooves are formed in the macromolecular material and aligned perpendicular to the first direction, each microgroove being separated by a ridge having a triangular cross-section, and each ridge having first and second sides meeting at an apex, wherein the first side has a shorter length than the second side. As a result, disclination does not occur and sufficient reliability against external forces and heat may be obtained. In addition, numerous methods are disclosed for forming the alignment layer.
