  • Publication number: 20120155505
    Abstract: In a method for detecting the freezing of water within a fuel cell, precise detection can be performed using a phenomenon specific to the time when water starts to freeze to allow a reduction in erroneous activation. Detection at an early stage after the start of freezing is allowed, and hence measures can be taken against an output reduction before the water within the fuel cell completely freezes.

  • Patent number: 8051204
    Abstract: An information asset management system in a network environment includes a monitoring program 11 that monitors operation events performed by users and creates terminal logs 12, a terminal log collection program 21 that stores an integrated log 22 created by collecting the terminal logs 12, and a correlation analysis program 31 that analyzes the whereabouts of information assets using the integrated log 22. When the user exports an information asset from the network environment and when the user imports the information asset into the network environment, the monitoring program 11 monitors these export and import events including feature values of the information assets. The correlation analysis program 31 compares a pre-export feature value of each information asset with a post-import feature value of each information asset to determine whether the information assets are identical and reports a list of information assets in the organization.

  • Publication number: 20110141188
    Abstract: Disclosed is a recording method in which an image is first formed on an intermediate transfer medium by ejection of ink and is then transferred to a printing medium. The present invention solves a problem regarding insufficient transfer of the image to the printing medium, which is caused by roughness on a surface of the ink image formed on the intermediate transfer medium due to non-uniform application amounts of ink. A transferability improving agent is applied in a controlled manner to an ink image which has been formed on a transfer drum by application of ink. The transferability improving agent is applied in a larger amount to regions with a relatively small application amount of the ink as compared with regions with a relatively large application amount of the ink.
