Publication number: 20080201940Abstract: The invention prevents reduction of a pickup rate even when a storage tape in use and a new storage tape are connected to each other with a connection tape. A component recognition camera takes an image of an electronic component held by a suction nozzle, and a recognition processing device performs recognition processing. When a positional shifting amount calculated by CPU based on the recognition processing result is more than ?, a board recognition camera takes an image of a storage portion of a storage tape storing a next electronic component to be picked up. When a positional shifting amount of the storage portion calculated based on the recognition processing result is more than ?, the CPU enables seam passage processing. Based on the image taking of the storage portion by the board recognition camera and the recognition processing by the recognition processing device which are performed each time the storage tape is fed N times, the CPU controls correction of a pickup position.Type: ApplicationFiled: February 25, 2008Publication date: August 28, 2008Applicant: Hitachi High-Tech Instruments Co., Ltd.Inventors: Akio WATANABE, Takuya Imoto, Yoshiharu Fukushima

Patent number: 6656872Abstract: Methods for producing ruthenium perovskite represented by a chemical formula LaRuO3, wherein La is lanthanum to which twelve oxygen ions are coordinated, Ru is ruthenium to which six oxygen ions are coordinated, and O is oxygen, which comprises reacting an aqueous mixed metal ion solution containing metal ions of La and Ru with a precipitate-forming liquid in a reaction container to co-precipitate hydroxides of La and Ru, and subjecting the precipitate to a heat treatment. Alternatively, the co-precipitated mass is deposited on a suitable carrier and subsequently heated to form supported LaRuO3. The co-precipitated La and Ru hydroxides can also be directly formed on a carrier by precipitation from a homogenous solution containing La, Ru and urea. This provides a uniform dispersion of co-precipitated hydroxides on a carrier, subsequent heating of which results in formation of supported LaRuO3. The materials thus obtained are to be used as efficient catalysts for certain reactions of environmental importance.Type: GrantFiled: February 19, 2002Date of Patent: December 2, 2003Assignee: National Institute for Materials ScienceInventors: Nitin Kumar Labhasetwar, Takefumi Mitsuhashi, Akio Watanabe
