Patent number: 7924493Abstract: A Faraday rotator mirror which is compact, allows high workability of manufacturing and has high reliability and high coupling efficiency is provided. The Faraday rotator mirror comprises a graded-index fiber, a Faraday rotator and a reflector mirror, wherein light incident via the graded-index fiber passes through the Faraday rotator to be reflected on the reflector mirror, and the reflected light passes through the Faraday rotator and emerges through the graded-index fiber.Type: GrantFiled: February 24, 2006Date of Patent: April 12, 2011Assignee: Kyocera CorporationInventors: Yusuke Takei, Tetsuya Suga, Satoru Tomie, Yasushi Sato, Michifumi Shoda

Kit for determining polysaccharide-binding activity of mononuclear cells present in peripheral blood
Patent number: 7553824Abstract: A kit for the determination of the ability of a peripheral blood mononuclear cell to bind to a polysaccharide herein provided comprises a detection reagent comprising a fluorescence-labeled immunostimulant polysaccharide; and a reference reagent comprising a fluorescence-labeled material of a polysaccharide different from that used in the fluorescence-labeled immunostimulant polysaccharide, and/or an immunostimulant polysaccharide which is not labeled with any fluorescent material and whose polysaccharide moiety is identical to that included in the fluorescence-labeled immunostimulant polysaccharide. The use of this kit would permit the estimation of the polysaccharide-binding ability of a peripheral blood mononuclear cell in a higher precision of estimation.Type: GrantFiled: May 9, 2008Date of Patent: June 30, 2009Assignee: Ajinomoto Co., Inc.Inventors: Tetsuya Suga, Yasuyo Suga, Masahiro Murata -
Patent number: 7449452Abstract: The ability of a polysaccharide to act as an immunostimulant may be assessed by comparing the degree of binding of a detection reagent, which contains a fluorescence-labeled version of the polysaccharide, with the binding of a reference reagent, which contains a fluorescence-labeled version of a different polysaccharide. The ability of a polysaccharide to act as an immunostimulant may also be assessed by comparing the degree of binding of a detection reagent, which contains a fluorescence-labeled version of the polysaccharide, with the binding of a different type of reference reagent, which contains both the same fluorescence-labeled version of the polysaccharide and an unlabelled version of the same polysaccharide.Type: GrantFiled: October 16, 2006Date of Patent: November 11, 2008Assignee: Ajinomoto Co., Inc.Inventors: Tetsuya Suga, Yasuyo Suga, Masahiro Murata

Patent number: 5410626Abstract: An optical coupler having a tapered fused region produced by locally heating the periphery of a plurality of aligned optical fibers, each having a core and a cladding, so that the optical fibers fuse together at the heated part, and then drawing the resulting fused region by pulling. The length of the fused region is not longer than 10 mm. The tapered fused region may be provided in such a manner that a plurality of optical fibers are disposed to intersect each other at a predetermined angle, and the intersecting portions are locally heated so as to fuse together and then subjected to pulling. The tapered fused region may be provided at each of two or more positions.Type: GrantFiled: June 23, 1993Date of Patent: April 25, 1995Assignee: Kyocera CorporationInventors: Michitaka Okuta, Tetsuya Suga, Akio Tsugawa, Kiyohiko Kuramoto
