Publication number: 20240399647Abstract: Control closely based on sets of winding data of a fiber bundle is performed even if at least one set of the winding data is skipped. A controller includes a data conversion unit, a reference data setting unit, a transfer unit, and a selector. The data conversion unit converts sets of first winding data generated based on winding conditions into sets of second winding data in which a processing order number is associated with information of a state of a winder. The reference data setting unit sets some of the second winding data as sets of reference data in advance. The transfer unit transfers a selected set of the second winding data to the winder, each time a unit time elapses. The selector is able to set an override value that is used for determining a skip number.Type: ApplicationFiled: May 29, 2024Publication date: December 5, 2024Applicants: Murata Machinery, Ltd., Toyota Jidosha Kabushiki KaishaInventors: Motohiro Tanigawa, Masatsugu Goyude, Toshihiro Matsui, Hirotaka Wada, Yoshihiro Kino, Hidehiro Takeoka, Yasuhiro Sakanashi, Dai Shimizube, Daigoro Nakamura, Wataru Sawabe

Patent number: 6324942Abstract: An engine crankshaft (1) made by forging, that has larger counter weights (8) without increasing a manufacturing cost. Engaging two dies with each other performs the forging. Each counter weight (8) has a plurality of inclinations (&thgr;1, &thgr;2) to facilitate removal of the dies from the crankshaft after the forging process is complete. The inclinations are reduced as they are apart from a die mating surface (P). The maximum thickness (T) of each counter weight (8) is not enlarged so that interference between the counter weights and neighboring parts is avoided. No machining is required after the forging process.Type: GrantFiled: January 4, 2000Date of Patent: December 4, 2001Assignee: Isuzu Motors LimitedInventors: Takayuki Koike, Toshihiro Matsui

Patent number: 5543903Abstract: A toner image fixing device includes a heat roller, and a backup roller engaged with the heat roller to form a nip therebetween. A paper carrying a toner image is passed through the nip whereby the toner image is thermally fused and fixed on the paper. The heat roller, which is stained by a part of the fused toner during the fixing process, should be cleaned before a toner image is fixed on a successive paper without staining. To this end, a cleaning roller made of a felt material is pressed against the heat roller so as to be rotated together with the heat roller by a frictional force acting therebetween. The cleaning roller must be periodically replaced. The fixing device is constituted such that the replacement of the cleaning roller can be easily and quickly carried out.Type: GrantFiled: January 4, 1995Date of Patent: August 6, 1996Assignee: Fujitsu LimitedInventors: Nobuo Fujita, Hideyuki Nanba, Masato Kawashima, Akihiro Komuro, Susumu Fujishima, Toshihiro Matsui
