Publication number: 20220120660Abstract: A cell observation system observes a cell moving in a flow path with a fluid, and includes a first imaging apparatus, a second imaging apparatus, and a control device. The first imaging apparatus includes a first optical system and a first imaging element, and captures an image of the cell at a first position in a moving direction. The second imaging apparatus includes a second optical system, in which a focus is adjusted based on a focus adjustment signal, and a second imaging element, and captures an image of the cell at a second position downstream of the first position. The control device obtains a passing position of the cell in a cross section of the flow path based on the image obtained by the first imaging element, generates the focus adjustment signal, and provides the signal to the second optical system.Type: ApplicationFiled: February 14, 2020Publication date: April 21, 2022Applicants: NATIONAL UNIVERSITY CORPORATION HAMAMATSU UNIVERSITY SCHOOL OF MEDICINE, HAMAMATSU PHOTONICS K.K.Inventors: Hirotoshi KIKUCHI, Hidenao YAMADA, Amane HIROTSU, Daisuke YAMASHITA, Shigetoshi OKAZAKI

Patent number: 11285483Abstract: A cell observation system observes a cell moving in a flow path with a fluid, and includes a first observation apparatus, a second observation apparatus, and a control device. The first observation apparatus includes an objective lens and a line camera. The second observation apparatus includes an objective lens and an area camera. The control device analyzes first imaging data output from the first observation apparatus to determine whether the cell satisfies a specific condition, instructs the area camera to output second imaging data of the cell determined to satisfy the specific condition, and analyzes the second imaging data output from the second observation apparatus to determine whether the cell is a specific cell.Type: GrantFiled: September 5, 2018Date of Patent: March 29, 2022Assignees: HAMAMATSU PHOTONICS K.K., NATIONAL UNIVERSITY CORPORATION HAMAMATSU UNIVERSITY SCHOOL OF MEDICINEInventors: Hirotoshi Kikuchi, Shigetoshi Okazaki, Hidenao Yamada, Yusuke Ozaki, Amane Hirotsu, Daisuke Yamashita

Patent number: 10180387Abstract: The identification apparatus includes a quantitative phase image acquisition unit, a feature quantity extraction unit, a learning unit, a storage unit, and an identification unit. The feature quantity extraction unit extracts a feature quantity of a quantitative phase image of a cell. The learning unit performs machine learning for a quantitative phase image of a known cell of which a type is known based on the feature quantity extracted by the extraction unit. The storage unit stores a result of the machine learning by the learning unit. The identification unit determines, based on the feature quantity extracted by the extraction unit for the quantitative phase image of an unknown cell of which a type is unknown, the type of the unknown cell using the learning result stored by the storage unit.Type: GrantFiled: July 23, 2015Date of Patent: January 15, 2019Assignees: NATIONAL UNIVERSITY CORPORATION HAMAMATSU UNIVERSITY SCHOOL OF MEDICINE, HAMAMATSU PHOTONICS K.K.Inventors: Yusuke Ozaki, Hidenao Iwai, Hiroyuki Konno, Hirotoshi Kikuchi, Toyohiko Yamauchi

Patent number: 7607527Abstract: The present invention relates to a wheel conveyor constructed by installing a wheel assembly, which includes wheels and support plates arranged on both sides and rotatably supporting axles of the wheels, in a groove of a frame material, the wheel conveyor being easily disassembled and cleaned, provided with a damping function, and also provided with a dust-trapping function. Wheels have axle pins, and support plates are provided with pin holes. A wheel assembly is constructed by inserting the axle pins into the pin holes to be rotatably supported. The cross-sectional shape of a frame material is formed such that first groove-like portions formed integrally with lip portions support the support plates to be movable in the longitudinal direction. Bottom groove-like portions formed integrally with a bottom wall are formed to splay more than the edges of the lip portions. The two groove-like portions are integrally jointed to each other through a joint portion.Type: GrantFiled: January 12, 2005Date of Patent: October 27, 2009Assignee: Yazaki Kako CorporationInventors: Atsuhiko Yazaki, Toshitsugu Mizushiri, Ryo Ando, Hirotoshi Kikuchi, Fumio Uematsu

Patent number: 7552808Abstract: A gravity wheel conveyor or roller conveyor is provided capable of braking for moderating and reducing the transfer speed of a relatively lightweight object being transported by using brake wheels or brake rollers, or of brake control for stopping the object being transported at a target position. In the wheel or roller conveyor that is constructed by arranging a plurality of freely rotatable wheels 4 or rollers 10 in the transporting direction of an object, which transports an object being transported 1 by its gravitational operation, one or more selected wheels 4 or rollers 10 are constructed as brake wheels 6 or brake rollers 12 each having an outer circumferential surface onto which a brake material 7 or 11 that is soft and high in its rebound resilience is fixed so as to protrude to form a diameter larger than the outer circumferential surface of each of the wheels or rollers.Type: GrantFiled: March 25, 2005Date of Patent: June 30, 2009Assignee: Yazaki Kako CorporationInventors: Atsuhiko Yazaki, Toshitsugu Mizushiri, Hirotoshi Kikuchi
