Patent number: 11975322Abstract: An optical positioning code disk, device and method for a microfluidic chip are provided. A cross section of an outer contour of the code disk is circular. N light transmissive openings are arranged uniformly around the code disk. The device includes: the code disk, a positioning pin, a rotating shaft, a motor, an internal photoelectric switch and an external photoelectric switch. A positioning surface is provided on the rotating shaft. The motor is fixedly connected with an end of the rotating shaft, and the other end of the rotating shaft passes through a center of the cross section of the code disk. The internal and external photoelectric switches are configured to identify the light transmissive openings on the code disk.Type: GrantFiled: October 26, 2020Date of Patent: May 7, 2024Assignee: CAPITALBIO TECHNOLOGY (CHENGDU) CO., LTD.Inventors: Chicheng Song, Guanbin Zhang, Yong Huang, Yong Tao, Ruoran Li, Hongcheng Zhou

Patent number: 11959844Abstract: There is provided a cool box for use in an automatic analyzer. The cool box has a box body and an air circulator. The box body has a receiving space capable of accommodating therein receptacles for analytes or reagents. The circulator has an intake portion, a fan, and an exhaust portion and operates to circulate air in the receiving space by rotation of the fan. The circulator further includes an inhibitor removing agent retaining portion on which a pouch is set. The pouch contains an analysis inhibitor removing agent for removing components (analysis inhibitor) which adversely affect or inhibit analysis of the analytes.Type: GrantFiled: July 30, 2021Date of Patent: April 16, 2024Assignee: JEOL Ltd.Inventors: Takashi Yaginuma, Kiyohiro Ishikawa, Yusuke Yamanaka

Patent number: 11946930Abstract: A device for use in the detection of binding affinities comprises a substrate, a planar waveguide arranged thereon and having an outer surface. The device further comprises a grating for coupling coherent light of a predetermined wavelength into the planar waveguide such that the coherent light coupled into the planar waveguide propagates through the planar waveguide in a predetermined propagation direction. An evanescent field of the coherent light propagates along the outer surface of the planar waveguide. The outer surface of the planar waveguide has receptor molecules arranged thereon capable of binding target samples to the receptor molecules such that light of the evanescent field is diffracted by the target samples bound to the receptor molecules. The receptor molecules are arranged along a plurality of straight parallel lines such that a portion of the light of the evanescent field is diffracted by the target samples bound to the receptor molecules.Type: GrantFiled: February 28, 2019Date of Patent: April 2, 2024Assignee: HOFFMANN-LA ROCHE INC.Inventor: Christof Fattinger

Patent number: 11906534Abstract: Provided is an automated analyzer comprising a temperature regulator that can be made more compact in size while maintaining high-precision temperature regulation. In a temperature-regulating unit (20) of the automated analyzer, a first chemical reservoir (1) is constituted by a large-diameter spiral-shaped pipe, and a second chemical reservoir (2) is constituted by a large-diameter chemical reservoir container. The first chemical reservoir (1), which is positioned upstream of the second chemical reservoir (2), has an internal capacity that is set so as to be greater than the volume of a single discharge of each of syringe pumps (29, 30, 31), and the second chemical reservoir (2) also has an internal capacity (volume) that is set so as to be greater than the volume of a single discharge of each of the respective syringe pumps (29, 30, 31).Type: GrantFiled: June 24, 2019Date of Patent: February 20, 2024Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Sunao Funakoshi, Takenori Okusa, Nobuyuki Isoshima, Koki Yokoyama
