Patent number: 9442324Abstract: A source line is provided on a layer above a substrate, and as a whole, extends in a first direction while meandering along the main surface of the substrate. An alignment film is provided on a layer above the source line, and specifies the alignment direction of a liquid crystal. A first protruding section along the source line is formed on the surface of the alignment film. In a cross-section that is parallel to the first direction and perpendicular to the substrate, and that passes through the source line, the inclination of an inclined end face on one side of the first protruding section in the first direction is steeper than the inclination of each inclined end face on the other side of the protruding section.Type: GrantFiled: May 15, 2015Date of Patent: September 13, 2016Assignee: Mitsubishi Electric CorporationInventor: Akinori Sumi

Patent number: 5986062Abstract: Human serum albumin obtained by gene manipulation techniques can be purified by a combination of specified steps in which a culture supernatant obtained from a human serum albumin-producing host is subjected to ultrafiltration, heat treatment, acid treatment and another ultrafiltration, followed by subsequent treatments with a cation exchanger, a hydrophobic chromatography carrier and an anion exchanger, and by salting-out to thereby obtain a pure form of human serum albumin which contains substantially no proteinous and polysaccharide contaminants, which is formulated into a pharmaceutical preparation. The thus obtained human serum albumin can further be purified by treating recombinant human serum albumin with a hydrophobic chromatography carrier at pH of 2 to 5 and a salt concentration of 0.4 to 1 and exposing the carrier to a pH of 6 to 8 and a salt concentration of 0.01 to 0.Type: GrantFiled: October 3, 1995Date of Patent: November 16, 1999Assignee: The Green Cross CorporationInventors: Takao Ohmura, Akinori Sumi, Wataru Ohtani, Naoto Furuhata, Kazuya Takeshima, Kaeko Kamide, Munehiro Noda, Masahide Kondo, Syoichi Ishikawa, Kazuhiro Oohara, Kazumasa Yokoyama, Nagatoshi Fujiwara
