  • Publication number: 20240112499
    Abstract: 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.

  • Patent number: 7166138
    Abstract: 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.

  • Patent number: 7027292
    Abstract: 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.

  • Patent number: 6493211
    Abstract: An electrolyte having a high conductivity, an excellent high-temperature life characteristic and leading to improvement of the shelf characteristic of an aluminum electrolytic capacitor. At least one phosphate ion producing compound and a chelating agent are added using a solvent largely composed of water. Therefor, an aluminum electrolytic capacitor comprising such an electrolyte has a low impedance, an excellent high-temperature life characteristic, and an improved shelf characteristic.
