Patent number: 8393543Abstract: An optical aberration is intentionally introduced into the optical system which produces the scanning beam of an optical code scanner, in order to produce a scanning beam which has plural focal points or waists at different distances from the scanner. The operating range of the scanner can thereby be increased by taking advantage of different beam waist locations when the optical code is at different distances from the scanner. In accordance with an embodiment of the invention, coma is intentionally introduced to an optical system providing a light beam for an optical code scanner. This provides a scanning beam with plural beam waists at different distances from the scanner. This may be accomplished by orienting the light source and focusing optical system so that their optical axes intersect or by introducing an optical member, such as a prism, between the original light source and the focusing optical system.Type: GrantFiled: December 10, 2008Date of Patent: March 12, 2013Assignees: Optoelectronics Co., Ltd., Opticon, Inc.Inventors: Zhihui Duan, Masayoshi Yamanouchi, Kazunori Noborio, Yo Tanaka, Hiroshi Hayakawa

Patent number: 8012258Abstract: The liquid surface position of the melt in the crucible in the silicon single crystal growth process utilizing the Czochralski method is monitored using the melt surface position on the occasion of seeding as a reference position and an estimated melt surface position can be calculated according to every situation, so that the distance between the melt and the thermal shield or water-cooling structure can be controlled with high precision. When the estimated melt surface position passes a preset upper limit and approaches the thermal shield, an alarm goes off and, further, when the melt comes into contact with the thermal shield or approaches the water-cooling structure, an alarm goes off if desired and, at the same time, the crucible is forcedly stopped from moving, so that a serious accident such as steam-incurred explosion resulting from the melt coming into contact with the water-cooling structure can be prevented.Type: GrantFiled: May 25, 2007Date of Patent: September 6, 2011Assignee: Sumco CorporationInventors: Hiroshi Hayakawa, Tokuji Maeda

Publication number: 20100181378Abstract: A compact barcode reader is provided in which the imaging lens and a linear sensor are in a straight line path with the barcode (no bend in path). By using a wide angle lens with a short back focus, it is possible to reduce the distance between the barcode and linear sensor to a fraction of what it was in the prior art. In addition, the maximum image height and the downward projection of the sensor are reduced to a fraction of what they were in the prior art. As a result, despite the straight line optical path, compact barcode reader becomes so small that it does not interfere with the operation of the beverage maker.Type: ApplicationFiled: March 9, 2007Publication date: July 22, 2010Applicants: Optoelectronics Co., Ltd., Opticon, Inc.Inventors: Hiroshi Hayakawa, Naoki Yoshihara, Naoya Niizeki, Yo Tanaka, Kazunori Noborio
