  • Patent number: 9136400
    Abstract: In this junction element 1, when a forward voltage is applied, a depletion layer is formed in a semiconductor layer 2, prohibiting electrons present in an electrode layer 4 to move into the semiconductor layer 2. For this reason, a majority of holes in a semiconductor layer 3 do not disappear by recombination with conduction electrons in the semiconductor layer 2, but reach the electrode layer 4 while diffusing into the semiconductor layer 2. Accordingly, the junction element 1 can serve as a good conductor for holes, while avoiding the influence of a resistance value, and allows a current to flow therethrough at a level equal to or more than that achieved by a semiconductor element formed of a Si or SiC semiconductor.

  • Patent number: 7813852
    Abstract: In a navigation system integrated with a diagnostic device, an arithmetic and control unit for diagnostic communication makes an inquiry to electronic control units, such as an engine control unit, a transmission control unit and a brake control unit connected a CAN, about data which is used for the diagnosis of trouble causes based on setting information stored in a memory through diagnostic communication. An arithmetic and control unit for navigation system receives messages responding to the inquiry to sift through the data to be collected based on the setting information in the memory and stores the collected information in a hard disk drive device. The setting information is updated by making an inquiry to an external center via a mobile communication network.
