  • Patent number: 7050007
    Abstract: A communication-capable electronic device is provided which includes a metallic housing (122) to accommodate electronic parts of the device, and a communication terminal (90) that makes communications with a communication-cable IC card (110) incorporating an antenna (115). The communication antenna (90) is located such that when the IC card is placed near the housing (122), the antenna (115) built in the IC card (110) faces, at a part thereof, a part of the communication terminal (90) while the rest of the antenna (115) of the IC Card (110) does not face the housing (122). Thus, it is possible to prevent the inductance in the antenna (115) of the IC card (110) from being reduced.

  • Publication number: 20050231858
    Abstract: A method for preventing corrosion of a contact, includes comparing a potential of a signal line connected to the contact with a predetermined potential corresponding to the corrosion of the contact; flowing a corrosion-prevention current into the contact when a result of the comparing shows that the contact is corroded; inputting into the signal line a signal used for judging a logical value of a connection state of the contact; and in the magnitude relation, setting the predetermined potential on another side of a threshold level used in the judging of the logical value of the connection state of the contact.

  • Publication number: 20050231876
    Abstract: An apparatus for preventing a contact from being corroded includes a power source, a signal line connected to the contact, a resistance connected to the signal line, a switching section, a comparator, and an overheat detecting section. The switching section has a switch between the power source and the signal line. An impedance of the switch is smaller than that of the resistance when the switch is turned on. The comparator compares a potential of the signal line with a predetermined potential to determine as to whether or not the contact is corroded. The comparator outputs a driving signal when the comparator concludes that the contact is corroded. The overheat detecting section detects whether or not temperature of the apparatus exceeds a predetermined temperature. The overheat detecting section decreases current flowing through the switching section when the temperature of the apparatus exceeds the predetermined temperature.

  • Publication number: 20050125501
    Abstract: A method is disclosed for setting a master node of a ring network that has adjacently connected nodes situated on rightward and leftward lines of a bidirectional transmission channel. The method includes the steps of: counting the number of nodes interposed between a designated node and each node other than the designated node on the rightward and leftward lines of the bidirectional transmission channel; and setting one of the nodes as the master node. The master node satisfies a relation of, NHC_L=NHC_R or NHC_L=NHC_R-1, wherein NHC_L is the number of interposed nodes counted from the leftward line, and NHC_R is the number of interposed nodes counted from the rightward line.
