Patent number: 11091432Abstract: An object of the present invention is to provide a method for producing a fluorinated organic compound with a high yield without using carbon tetrachloride in view of the fact that the production of a fluorinated organic compound with a sufficient yield was impossible for a hitherto-known method that uses a fluorinating agent that contains IF5-pyridine-HF alone. Another object of the present invention is to provide a fluorinating reagent that is capable of achieving this object. The present invention provides a composition comprising (1) IF5 and (2) an aprotic solvent (with the proviso that carbon tetrachloride is excluded), wherein the aprotic solvent is contained in an amount within a range of 50 mass ppm to 20 mass %.Type: GrantFiled: April 19, 2016Date of Patent: August 17, 2021Assignees: DAIKIN INDUSTRIES, LTD., NATIONAL UNIVERSITY CORPORATION HOKKAIDO UNIVERSITYInventors: Masahiro Higashi, Yosuke Kishikawa, Shoji Hara

Patent number: 11071460Abstract: In a photoacoustic measurement apparatus and a photoacoustic measurement system, it is possible to generate blood flow information using a photoacoustic image without requiring a separate tourniquet. A light source emits measurement light. A probe detects a photoacoustic wave generated in a subject after measurement light is emitted to the subject in each of the avascularized condition in which the subject is avascularized and the non-avascularized condition in which the subject is not avascularized. Photoacoustic image generation unit generates a photoacoustic image based on the detection signal of the photoacoustic wave. Blood flow information generation unit generates blood flow information based on the signal value of a photoacoustic image in a region of interest set in the photoacoustic image. The avascularization of the subject is performed by pressing the probe against the subject.Type: GrantFiled: June 30, 2017Date of Patent: July 27, 2021Assignee: FUJIFILM CorporationInventors: Kaku Irisawa, Dai Murakoshi, Tetsuro Ebata, Shoji Hara
