Publication number: 20240112499Abstract: An image analysis device comprising: an input interface to acquire image data indicating an image of an operator performing task; and a controller to detect the task performed by the operator sequentially, based on the image data, to generate task detection information indicating a detection result of the task, wherein the task includes a plurality of processes performed by the operator, and the controller compensates the task detection information by interpolating a detection result of the task within an undetected period, in accordance with a pre process and/or a post process of the undetected period, the undetected period being a period in which the task is not detected, the pre process being a process of the task detected previously to the undetected period, and the post process being a process of the task detected subsequently to the undetected period.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Tomoaki Itoh, Tomokazu Ichiriki, Hidehiko Shin, Daijiroh Ichimura

Patent number: 7166138Abstract: A cathode foil and an anode foil, with an oxidized film layer formed on the surface and a separator interposed therebetween, are wound together to form a capacitor element, and prior to subjecting the capacitor element to chemical repair the content of the binder in the separator is adjusted to 10 to 20% with respect to the total weight of the separator. After the chemical repair, the capacitor element is immersed in mixed liquid prepared by mixing a polymerizable monomer and an oxidizing agent together with a predetermined solvent, a polymerization reaction of the electroconductive polymer is induced in the capacitor element, and a solid electrolyte layer is formed. The capacitor element is then inserted in an outer case; sealing rubber is mounted in the open-end portion and sealed with a tightening operation; and the unit is thereafter aged to form a solid electrolytic capacitor.Type: GrantFiled: February 3, 2006Date of Patent: January 23, 2007Assignee: Nippon Chemi-Con CorporationInventors: Naoki Anzai, Shogo Aizawa, Tomohiro Matsuzaki, Norihito Fukui, Atsushi Yoshizawa, Hidehiko Itoh, Atsushi Yamada, Katsumi Abe

Patent number: 7027292Abstract: Negative electrode foil and positive electrode foil having an oxide coating layer formed on the surface thereof with a separator, the separator containing a binder constituted of a compound having a vinyl group, interposed therebetween are wound up to thereby form a capacitor element. The content of binder in the separator is adjusted to 10–20% based on the total weight of separator before subjecting the capacitor element to restoration and chemical conversion. After the restoration and chemical conversion, the capacitor element is immersed in a liquid mixture prepared by mixing a polymerizable monomer, an oxidizer and a given solvent together so that polymerization reaction of conductive polymer is effected in the capacitor element to thereby form a solid electrolyte layer. The thus obtained capacitor element is inserted in a sheath case, and its opening end is fitted with sealing rubber. Sealing is accomplished by fastening operation, and aging is performed. Thus, a solid electrolytic capacitor is obtained.Type: GrantFiled: March 28, 2003Date of Patent: April 11, 2006Assignee: Nippon Chemi-Con CorporationInventors: Naoki Anzai, Shogo Aizawa, Tomohiro Matsuzaki, Norihito Fukui, Atsushi Yoshizawa, Hidehiko Itoh, Atsushi Yamada, Katsumi Abe
