  • Publication number: 20130228228
    Abstract: Provided are a temperature sensor 15 for detecting a temperature surrounding an EGR valve 12, judging means (IC chip 16) for judging on the basis of the detected temperature from the temperature sensor 15 whether an inside of a gas passage in the EGR valve 12 is frozen or not and a controller 17 for controlling an operation of the EGR valve 12. The controller 17 is adapted to forbid and allow an output of an operating command 17a to an actuator 14 for the EGR valve 12 when an inside of a gas passage in the EGR valve 12 is judged by the judging means (IC chip 16) to be frozen or unfrozen, respectively.

  • Publication number: 20020154628
    Abstract: Only information that has reached a disclosure day among information registered in a database of a first information providing server (32) having access through an intranet (10) is downloaded to a second information providing server (42) having access through the Internet (20), and the information is provided to clients (22 to 26) that are provided with access rights and that are connected to the Internet (20) from the second information providing server (42). As a result, information that has not reached the disclosure day can be prevented from being leaked by an illegal access to the second information providing server (42). The establishment of access rights makes it possible to hierarchize clients (12 to 16, 22 to 26) connected to the intranet (10) and to the Internet (20).
