  • Patent number: 10428995
    Abstract: A heat-insulated pipe assembly includes a pipe allowing a fluid to flow therethrough, and a heat insulating member covers at least a part of the pipe. The pipe is used in an exhaust gas purification system using an SCR catalyst. The heat insulating member has a closed-cell structure and suppresses an increase in a temperature of the fluid due to heat exchange with air. In the exhaust gas purification system using the SCR catalyst, the interior of the pipes is thermally insulated from the exterior by the heat insulating member. Thereby an increase in the temperature of the fluid flowing through the pipe due to heat exchange with air is suppressed.

  • Patent number: 10044054
    Abstract: A separator of a fuel cell to be laminated while sandwiching a membrane electrode assembly forming a power generation region includes a source connection point tab for inputting and outputting an alternating current for internal resistance measurement, a sense connection point tab for detecting a potential of the alternating current input and output to and from the source connection point tab and separation portion configured to separate the sense connection point tab from a current path of the alternating current for internal resistance measurement from the source connection point tab to the power generation region.

  • Patent number: 7764099
    Abstract: DLL circuit operating more stably at reset. Voltage comparator circuit 21 outputs comparison result signal to hold circuit 22 at first level when power supply voltage VAA is not higher than reference voltage REF and at second level when power supply voltage VAA exceeds reference voltage REF. Hold circuit 22 outputs reset signal RST that it has received to DLL circuit 23 as it is when comparison result signal indicates first level and at second level, hold circuit 22 holds reset signal RST until comparison result signal becomes first level and then outputs it to DLL circuit 23.

  • Publication number: 20090019014
    Abstract: Version identification information for identifying the version of content data stored in a multidimensional database is generated preliminarily. When the version identification information of a predetermined version, multidimensional identification information (information indicating the combination of members) and update data are received, the content data updated on the basis of the update data is stored in a version management table so as to be associated with the version identification information of the predetermined version and the multidimensional identification information. The content data of the predetermined version is identified on the basis of the version identification information and the multidimensional identification information.
