  • Patent number: 7917406
    Abstract: Introduction service is supported, in order to activate and facilitate community activities. A community management center 1 searches for offered-service information that matches at least partly with an application designated by a coordinator terminal 2, and selects participants specified by detected offered-service information, as introduction candidates. Then, an introduction candidate list that describes private information, desired terms, and possessed value of ticket for each of the selected introduction candidates is displayed on a coordinator terminal 2. When the coordinator terminal 2 selects a participant to be introduced to the applicant, out of the introduction candidates described in the introduction candidate list, then, the private information and the desired terms of selected participant is displayed on a participant terminal 3 of the applicant.

  • Publication number: 20100178564
    Abstract: The present invention provides a highly reliable energy storage device capable of preventing a reaction current from flowing in a carbon nanotube electrode by ionizing a catalyst metal or a substrate metal to cause the metal to flow out to an electrolytic solution. An energy storage device of the present invention includes: at least a pair of electrode bodies that are a cathode and an anode; and an electrolytic solution. At least one of the electrode bodies is configured such that a layer of carbon nanotubes is formed on an electric conductor. A coupling region where one ends of the carbon nanotubes are coupled to and electrically connected to the electric conductor and a non-coupling region where ends of the carbon nanotubes are not coupled to the electric conductor are formed on a surface of the electric conductor. The carbon nanotubes having one ends connected to the coupling region are toppled to cover a surface of the non-coupling region.

  • Patent number: 7652784
    Abstract: In the image forming apparatus, upon reception of a job containing a file to be printed, it is determined whether or not the job contains a template indicating that a plurality of files are to be merged. If it is determined that the job contains the template, then the job is stored in a storage section. Based on the template, it is analyzed whether or not all jobs containing files to be merged have been stored in the storage section. If it is determined that all the jobs have been stored in the storage section, then control is exerted based on the template so as to merge and print the files contained in all the jobs. Thus, a plurality of files can be automatically merged and printed, and therefore the workload on the user can be reduced.
