Publication number: 20230329551Abstract: An ophthalmic apparatus includes an examination unit examining a subject eye, a drive unit moving the examination unit relative to the subject eye, a first imaging unit capturing a face image, a second imaging unit capturing an anterior segment image of the subject eye, a controller, and first and second acquisition units. The controller performs an adjustment process including a position acquisition of the subject eye based on the face image, a first drive control such that the subject eye is positioned within an imaging range of the second imaging unit based on the acquired position, and a second drive control based on the anterior segment image to adjust a position of the examination unit relative to the subject eye. The first acquisition unit acquires the position of the subject eye through a detection. The second acquisition unit acquires the position of the subject eye through an input operation.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Applicant: NIDEK CO.

Patent number: 7232261Abstract: An optical ferrule is disclosed in which a concave portion 17c having a gate G in resin molding disposed therein is formed in a ferrule body 11. According to this constitution, it is possible to easily cut a flash 10 left after a gate of the concave portion 17c of the ferrule body 11 is cut after molding with a gate cutter, so that, when the ferrule body 11 is fitted in a housing of an MPO connector and the like, the problem that the flash 10 protrudes from the concave portion 17c and the flash 10 hitching to an inner wall of the housing dose not occur. Accordingly, the labor required for removing the flash 10 by polishing can be eliminated, and hence productivity of the ferrule body 11 can be improved. Thus, a large number of ferrule bodies 11 can be automatically manufactured without requiring much manpower.Type: GrantFiled: April 20, 2000Date of Patent: June 19, 2007Assignee: Fujikura Ltd.Inventors: Akito Nishumura, Toru Arikawa, Yasuhiro Tamaki

Patent number: 5706930Abstract: When a carrier arm is retracted, a semiconductor wafer carried thereon passes between three light-emitting elements and three light-detecting elements associated therewith. At this time, a controller determines six points on the outer circumferential edge of the semiconductor wafer based on signals from sensors made up of the light-emitting elements and the light-detecting elements. The controller selects three of the determined points, determines the center of a circumscribed circle passing through the selected three points, and regards the determined center as the center of the semiconductor wafer. Then, the controller controls movement of the semiconductor wafer toward a rotary-cup coating device, an evacuating drying device, or an edge cleaning device based on the center of the semiconductor wafer.Type: GrantFiled: April 24, 1996Date of Patent: January 13, 1998Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Tsutomu Sahoda, Koji Ueda, Hidenori Miyamoto, Toru Arikawa
