  • Publication number: 20240378341
    Abstract: A lifetime prediction method for nitride semiconductor light-emitting element that is a method for predicting lifetime of a nitride semiconductor light-emitting element, the method including a model creation step of creating a trained model by learning at least a correlation of at least one of a composition parameter or a physical property parameter of a layer constituting the nitride semiconductor light-emitting element and a manufacturing condition parameter, relative to lifetime of the nitride semiconductor light-emitting element; and a lifetime prediction step of predicting lifetime using the trained model. In the model creation step, at least one of the composition parameter or the physical property parameter of a predetermined layer of the nitride semiconductor light-emitting element is used for the learning, and a growth temperature of the predetermined layer is used as the manufacturing condition parameter for the learning.

  • Patent number: 7676029
    Abstract: To provide a technology indicating guidance for a usage method of information equipment and for solving an abnormality of the information equipment to not only users having knowledge about terminology of the information equipment but also users having none of the knowledge about the terminology of the information equipment. A guidance apparatus receives identifying information of information equipment from a device, reads an image from a database containing images about the information equipment with respect to the received identifying information, creates guidance information containing the read image, transmits the created guidance information to the device, receives information determined by a manipulation about the guidance information on the device, and controls so as to read the image used next for the guidance information from the received information.

  • Patent number: 7085761
    Abstract: In the present invention, information for content, software or both that a user set as a desired operation target of a content search rank changing process is stored in a operation target management table. Information for software active during a content search processing is stored in a currently active software management table. In case the content or software relates to the retrieved content as search results is present in the operation target management table or the currently active software management table, the relevancy rating of the retrieved content is calculated by adding a prescribed value to the relevancy rating of the retrieved content. Then, the retrieved content is sorted based on the relevancy rating and outputted in order sorted at a display device.

  • Patent number: 6654744
    Abstract: The information categorizing apparatus comprises a feature element extraction section which extracts a feature element for each categorizing category from a plurality of sample texts included in the categorizing sample data in which a sample text group and a plurality of categories are associated with each other in advance. Further, a categorizing method determination section determines a categorizing method based on the categorizing sample data. A categorizing learning information generation section generates categorizing learning information representing a feature for each category, based on the extracted feature elements, in accordance with the determined categorizing method. An automatic categorizing section categorizes a new text group to be categorized for each category, in accordance with the determined categorizing method and the categorizing learning information.
