Patent number: 11619644Abstract: An analysis device employs an analysis kit including a chip provided with a capillary through which a sample flows and a cartridge superimposed on the chip and provided with a liquid reservoir. The analysis device includes a guide-in section into which the analysis kit is guided, a placement section on which the analysis kit placed so as to be supported, a pusher member that pushes the analysis kit from one side face of the analysis kit, contact members that oppose another side face on an opposite side in the horizontal direction to the one side face of the analysis kit placed on the placement section, and contact the other side face of the analysis kit being pushed in by the pusher member so as to position the analysis kit in the horizontal direction, and a measurement member that measures a component present in the sample in the analysis kit.Type: GrantFiled: August 29, 2022Date of Patent: April 4, 2023Assignee: ARKRAY, Inc.Inventors: Akihiro Yamamoto, Shigeru Kitamura, Naoto Shichi

Patent number: 11327006Abstract: An analysis device includes a guide-in section, a placement section, an illumination member, a pressing member, and a measurement member. The guide-in section is configured to guide a rectangular block shaped analysis kit containing a sample. The analysis kit is placed on the placement section in the guide-in section. The illumination member is inserted into an insertion hole formed in the analysis kit, contacts a bottom of the insertion hole, and illuminates light onto the sample. The pressing member is configured by a separate body to the illumination member and presses the analysis kit such that the analysis kit placed on the placement section is sandwiched between the pressing member and the placement section and retained at a predetermined position. The measurement section measures a component present in the sample using light illuminated from the illumination member onto the sample in the analysis kit placed on the placement section.Type: GrantFiled: October 26, 2018Date of Patent: May 10, 2022Assignee: ARKRAY, Inc.Inventors: Akihiro Yamamoto, Naoto Shichi

Patent number: 11231028Abstract: A method of driving a pump is used in a pressure-applying apparatus, the apparatus including a flow passage, a pump configured to impart pressure into the flow passage, an opening and closing valve configured to open and close the flow passage, a pressure detector configured to detect pressure in the flow passage, and an atmospheric air open valve configured to open an interior of the flow passage to atmospheric air. The method includes driving the pump after closing the opening and closing valve and opening the atmospheric air open valve, and evaluating a state of the pump, based on one of: the pressure detected by the pressure detector at a time at which a predetermined time period has elapsed after closing the atmospheric air open valve, and a time from closing of the atmospheric air open valve until detection of a predetermined pressure by the pressure detector.Type: GrantFiled: October 26, 2018Date of Patent: January 25, 2022Assignee: ARKRAY, Inc.Inventors: Naoto Shichi, Daisuke Matsumoto, Takanari Shigemitsu

Patent number: 10126631Abstract: Excitation light of two wavelengths is incident to an optical crystal from a first face side, and a terahertz wave THzb is generated from a second face, and the excitation light that has passed through the optical crystal is reflected, made incident to the optical crystal from the second face side, and a terahertz wave THza is generated from the first face. Terahertz waves with similar characteristics to each other are thereby generated reliably in plural directions.Type: GrantFiled: January 3, 2014Date of Patent: November 13, 2018Assignee: ARKRAY, Inc.Inventors: Hirohisa Uchida, Naoto Shichi
