Patent number: 11959914Abstract: The automatic analyzer includes: a sample dispensing unit that dispenses a sample into a reaction vessel; a reagent dispensing unit that dispenses a reagent into the reaction vessel; a control unit that controls the sample dispensing unit and the reagent dispensing unit; and a measurement unit that measures a mixed solution of the sample and the reagent mixed in the reaction vessel. The reagent includes three types of reagents of: a first reagent that specifically binds to an antigen in the sample; a second reagent that specifically binds to a site different from that to which the first reagent binds with respect to the antigen and has a label to be detected by the measurement unit; and a third reagent that specifically binds to a site different from the binding site of the first reagent and the antigen and contains insoluble carriers.Type: GrantFiled: January 29, 2019Date of Patent: April 16, 2024Assignees: HITACHI HIGH-TECH CORPORATION, ROCHE DIAGNOSTICS OPERATIONS, INC.Inventors: Tatsuki Takakura, Kenta Imai, Takaaki Hagiwara, Yoshihiro Yamashita, Taku Sakazume, Beatus Ofenloch-Haehnle, Michaela Windfuhr, Ursula Pauselius-Fuchs, Rita Haerteis

Patent number: 11806899Abstract: The present invention provides a technology in production of a prepreg and enhances the production efficiency, in which the technology allows the arrangement property and rectilinearity of reinforcing fibers to be well maintained and allows any resin to be applied stably at a high speed. A prepreg is produced by a method which includes: discharging a molten resin in planar form to form a resin film, and applying the resin film onto a reinforcing fiber sheet conveyed continuously, wherein the reinforcing fiber sheet is conveyed substantially in the horizontal direction, and wherein an angle made between the discharge direction of the resin and the conveyance direction of the reinforcing fiber sheet 1a is 80° or less.Type: GrantFiled: February 22, 2018Date of Patent: November 7, 2023Assignee: Toray Industries, Inc.Inventors: Junichi Aoki, Takashi Ochi, So Nishino, Satoshi Enzaki, Takaaki Yamashita

Patent number: 11208535Abstract: The invention enhances the production efficiency in the production of prepreg by allowing the arrangement property and rectilinearity of reinforcing fibers to be well maintained, allowing the basis weight uniformity of an applied resin to be good, and further allowing a high line speed and suppression of contamination in the process to be achieved. The invention provides a method of producing a prepreg, which includes: discharging a molten resin from a discharge portion; introducing the discharged resin by an air flow; and capturing the discharged resin on a reinforcing fiber sheet conveyed continuously, wherein a key point is that the discharged resin is captured in a region in which the reinforcing fiber sheet is conveyed substantially in planar form.Type: GrantFiled: February 22, 2018Date of Patent: December 28, 2021Assignee: TORAY INDUSTRIES, INC.Inventors: Takashi Ochi, Junichi Aoki, Takaaki Yamashita

Patent number: 8647698Abstract: A fermentation product (fermented food) that has high functionality by subjecting a fructan-containing material (in particular, a material including garlic or rakkyo containing fructan at a high concentration) directly to lactic acid fermentation without performing a heat treatment or an enzymatic treatment. More specifically, provided are: a fermentation product having an immunopotentiating effect, which is obtained by lactic acid fermentation of a fructan-containing material using a lactic acid bacterium Lactobacillus plantarum S506 strain (MITE BP-643) having fructan-utilizing ability, a mutant strain of the S506 strain having fructan-utilizing ability, or a strain isolated from Lactobacillus plantarum and having the same bacteriological properties as those of the S506 strain; and a fermented food which contains the fermentation product.Type: GrantFiled: February 15, 2010Date of Patent: February 11, 2014Assignee: Fuji Sangyo Co., Ltd.Inventors: Shuichi Kusano, Hiroshi Tamura, Takaaki Yamashita
