  • Publication number: 20240079575
    Abstract: Provided is a secondary battery including a negative electrode, a positive electrode, a separation layer in contact with an active material-containing layer of the negative electrode, and an aqueous electrolyte. A first concentration corresponding to a first metal concentration represented by Equation 1 (first metal concentration=atomic concentration of Hg, Pb, Zn, and/or Bi/sum of atomic concentrations of elements B to U in periodic table, excluding carbon and oxygen) in a boundary region between the active material-containing layer and the separation layer is 2% or more and 8.2% or less. A ratio of the first concentration to a second concentration corresponding to the first metal concentration represented by Equation 1 in the active material-containing layer excluding the boundary region is 2.5 or more and less than 4.

  • Publication number: 20060026282
    Abstract: A decentralized system managing method is provided for adapting a decentralized service changing day by day without having to recreate the overall existing application and for optimally executing the application without having to burden the overhead of the network load. The managing method is arranged to obtain the log information in executing the program, accumulate and work the log information, and present the result to the user. At a time, the managing method is served to create and issue an improving instruction for making the application execution the most approximate according to the optimization rule instructed by the user.

  • Patent number: 6983268
    Abstract: Even when a user does not know a structure of a computer readable program, a technique capable of analyzing log information is provided. A log analyzing method for analyzing log information outputted when a program is executed by a computer is comprised of: a step for acquiring log information outputted when a program is executed to thereby read the acquired log information; a step for accepting a user designation condition indicative of log information which is extracted; a step for extracting information from the log information based upon the accepted user designation condition, and for judging as to whether or not each of operations while the program is executed can satisfy an initial condition thereof so as to analyze a cause of an error occurred while the program is executed; and a step for providing a result of the error cause analysis to a user.

  • Publication number: 20050033779
    Abstract: Database optimizing method and system are provided to optimally locate data. Only data satisfying conditions desired by a user is extracted among an access log. Values of a part of the data are translated on the basis of a translation table, and aggregated on the basis of aggregation condition rules. The obtained aggregation result is presented to the user. In addition, data in the database are optimally relocated on the basis of the obtained aggregation result.

  • Publication number: 20030014273
    Abstract: A method and system for assisting application preparation are provided for assisting in preparing an application for making a document-based application to a public organization. A world-wide standard reference unit acquires and utilizes information on a world-wide standard which defines contents that should be described in the application. A country-based published information reference unit acquires and utilizes information on a standard unique to each country which is defined in detail in conformity to the world-wide standard, and information on published applications and examinations unique to each country. A document preparation management assisting unit assists in preparing application documents based on the acquired information on the world-wide standard, information on the standard unique to each country, and information on the application and examination.

  • Publication number: 20020143737
    Abstract: A retrieval device and retrieval service are provided for reserved retrieval of document information, so that, when there are duplicates in retrieval conditions registered by a plurality of users, these duplicates are eliminated from the retrieval conditions to thereby execute efficient retrieval. Copies of information regarding the retrieval result are made correspondingly to the number of the duplicates among the users and the copied information is expanded respectively in accordance with the registered retrieval conditions desired by the users. The expanded information is edited in a form desired by the user, and the edited result is delivered to a delivery destination such as an e-mail address registered by the user.

  • Publication number: 20020019822
    Abstract: Different heterogeneous databases that are accessible in at least one of the data management method and the data structure. A heterogeneous database manager accepts an access request in a common format, identifies a database management system to be accessed, and accesses the database management system to acquire a database and a data item to generate an access information table. The heterogeneous database manager references the table and generates a access command specific to the database management system to manage, collect, create, and update data desired by the user.
