Publication number: 20240119215Abstract: For example, an I/O circuit is formed by freely combining a plurality of kinds of standard cells included in a cell library. The plurality of kinds of standard cells include at least first standard cells and a second standard cell. The first standard cells include first protection elements and a first power line formed in a region over the first protection elements to conduct to the first protection elements. The second standard cell includes a second protection element formed in a layout identical with that of the first protection elements, and a second power line formed in a region over the second protection element to conduct to the second protection element while being isolated from the first power line.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: Kenichi YOSHIMURA, Hiromitsu KIMURA, Tomokazu OKADA, Yuji KUROTSUCHI

Publication number: 20180042452Abstract: A spiral tube that forms a flexible tube used for an insertion section is formed by spirally and densely winding a band-like element wire, and being coated by an external layer from the outer periphery side. In the element wire, adjustment portions are arranged in intervals that are greater than half the circumference of the spiral along the longitudinal direction of the band. A plurality of retaining portions are formed as holes or bottomed holes in a continuous manner. The retaining portions are shifted in the circumferential direction of the longitudinal axis so that the retaining portions that are formed in the adjacent portions of the spirally wound element wire would not be next to each other in the direction parallel to the longitudinal axis.Type: ApplicationFiled: October 13, 2017Publication date: February 15, 2018Applicant: OLYMPUS CORPORATIONInventors: Hiromitsu OKADA, Kohei ARAKI

Patent number: 4753498Abstract: The present invention relates to an optical reader for scanning a surface to be scanned by using information beam ray such as laser beam ray and optically reading a recorded information such as bar code recorded in the surface to be scanned. The optical reader is constituted such that optical beam emitted from a light source is reflected on a first rotary multiface mirror to scan on a surface to be scanned, and information beam reflected on the surface to be scanned is reflected on a second rotary multiface mirror to guide to an opto-electric transforming means. A scanning optical path for permitting the optical beam from the light source to pass therealong is formed independently from a reflecting optical path for permitting the information beam from the surface to be scanned to pass therealong.Type: GrantFiled: March 20, 1986Date of Patent: June 28, 1988Assignees: Tokyo Kogaku Kikai Kabushiki Kaisha, Kabushiki Kaisha ToshibaInventors: Hiroshi Saitoh, Hiromitsu Okada, Hironobu Watanabe, Hiroshi Watanabe, Michio Waki, Keizo Shiihara, Hiromitsu Kijima, Yukito Matsuo, Tsuyoshi Ishida
