  • Publication number: 20100083093
    Abstract: A content conversion system of the present invention includes a divider that determines a division point in content data using a determination reference based on a distance (content distance) on a data description between content components in the content data, and divides the content data based on the determination result, a reconstructing unit that reconstructs the divided data as the respective content data, and a division parameter setter that, based on the difference between a variation in distances in the data description between content components in reference content data and a variation in distances in the data description between content components in division target content data, corrects an optimum determination reference of the reference content data, and creates a determination reference for the division target content data.

  • Publication number: 20100065540
    Abstract: Setter transmits information of an instruction that changes a content of a welding condition item to welder power supply, which then selects a content of the welding condition item from welding-condition-item memory & selector based on the information. At the same time, welder power supply selects data of the welding condition, which data corresponds to the content selected, and then transmits the selected content to setter, which displays the content on display section. The foregoing structure allows setter to set a content of a welding condition item for welder power supply without modifying or replacing setter presently used.

  • Publication number: 20090228413
    Abstract: A plural number of training vectors are randomly selected from a total of unused training vectors, and from among the selected training vectors, a vector having the largest error amount is extracted. Subsequently, the extracted vector is added to the already used training vector so as to update the training vector, and the updated training vector is used to learn the SVM. When the largest error amount becomes smaller than a certain setting value ? or when the already used training vector becomes larger than a certain value m, learning of a first phase is stopped. In learning of a second phase, the learning is performed on a predetermined number of or all of the training vectors having a large error amount.

  • Patent number: 6822404
    Abstract: An energy-saving, high-outputting and high-efficiency, electric discharge type of illumination apparatus and associated units having thin divisional electrode pieces arranged at relatively narrow intervals on an electrode-application area, which is defined on the bottom of a flat container. The divisional electrode pieces are fixed to the electrode-application area with an intervening sheet of good electrically insulating and thermally conductive material laid therebetween. A front glass having a fluorescence coating on its inside is placed to confront the electrode-application area. Cooling water is circulated in the electrode-application area for cooling the divisional electrode pieces. A multi-poled magnet sheet arranged outside the electrode-application area is aligned with the electrode-to-electrode space. Lower frequency power supplies are connected to the divisional electrodes to supply that with voltages of the same amplitude.
