Patent number: 11926246Abstract: In a local cart traveling system, a frame track includes first and second metal rails each with an L-shaped cross section and facing each other. A local cart is within the frame track, and includes a first electricity receiving tire and a second electricity receiving tire to travel on horizontal travel surfaces of the rails. A voltage supplier supplies an AC voltage to the travel surfaces, so that the first metal rail and a first electricity receiving tire define a first capacitor and the second metal rail and the second electricity receiving tire define a second capacitor. The local cart includes a power receiver to receive AC power, and a travel motor that receives power after the AC power is rectified. The frame track includes a connecting plate as an electrical insulator covering portions of the surfaces of vertical walls of the first metal rail and the second metal rail.Type: GrantFiled: June 1, 2018Date of Patent: March 12, 2024Assignees: MURATA MACHINERY, LTD., NATIONAL UNIVERSITY CORPORATION TOYOHASHI UNIVERSITY OF TECHNOLOGYInventors: Minoru Mizutani, Kazuhiro Ishikawa, Masafumi Hayakawa, Takashi Ohira, Naoki Sakai, Hiroki Kuniyoshi, Makoto Teramoto

Patent number: 7750951Abstract: An image sensor repeatedly receives a light from an object through a lens and generates images of the object. A differential image generating unit generates a differential image from at least two images. A detector detects a change cycle or an intensity of an external light. An evaluation unit evaluates an influence of the external light and derives an optimal timing in which a minimum influence of the external light is attained. A controller controls a timing of receiving the light of the image sensor, depending upon the optimal timing derived by the evaluation unit, and repeatedly synchronizes a term of two timings with the change cycle of the external light by shifting the term into the change cycle by a unit of predetermined phase difference.Type: GrantFiled: February 11, 2008Date of Patent: July 6, 2010Assignee: Kabushiki Kaisha ToshibaInventors: Shunichi Numazaki, Miwako Doi, Minoru Ishikawa, Akira Morishita, Naoko Umeki

Publication number: 20080291292Abstract: An image input apparatus. A detection section detects a change cycle of an intensity of an external light inputted to a camera. A timing control section synchronizes the change cycle of the intensity of the external light with a plurality of input timings of the camera by changing a phase difference in order. An evaluation section compares each storage quantity of the external light inputted to the camera at the plurality of input timings synchronized by the timing control section for each phase difference. A selection section selects the phase difference whose difference of the storage quantities of the external light is smallest from all phase difference changed by the timing control section.Type: ApplicationFiled: February 11, 2008Publication date: November 27, 2008Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Shunichi NUMAZAKI, Miwako Doi, Minoru Ishikawa, Akira Morishita, Naoko Umeki
