  • Patent number: 8239324
    Abstract: A mobile terminal capable of causing the user side to grasp whether or not a credit settlement service stops with a simple operation is provided. In the mobile terminal 10, validation and invalidation of a storage area within an IC chip assigned to an issuer application corresponding to one issuer are switched based on switching instruction information received from an issuer terminal 20 managed by one issuer. Then, when the issuer application starts, there is displayed in a lump whether or not the respective issuer applications are available on a display part 16, based on state information indicating whether or not the respective storage areas are validated. Therefore, in the mobile terminal 10, even if plural issuer applications are stored, it is possible to cause the user side to grasp which kind of the credit settlement service stops, with a simple operation of only starting a management application.

  • Publication number: 20080013011
    Abstract: A display panel module such as a liquid crystal display (LCD) panel module in an electronic apparatus is designed to receive a driving signal of a predetermined frequency. An electrically conductive frame or bezel of the display panel module tends to suffer from the transmission of electromagnetic waves which are related to the wavelength of the driving signal. An electrically conductive member is located behind the display panel and electrically connected to the electrically conductive frame. The electrically conductive member serves to diverge the electromagnetic waves out of the electrically conductive frame. This divergence of the electromagnetic waves serves to suppress the electromagnetic radiation out of the electrically conductive frame.

  • Publication number: 20020189086
    Abstract: A grounding assembly, preventing discharge induced by charging and thereby suppressing the propagation of noise, comprising a grounding member to be electrically connected to grounding terminals of computers and a conductive member surrounding the grounding member and having a predetermined resistance. The resistance value of the conductive member is set to at least a value preventing contact current when another metal body touches the grounding member, for example, at least 2.5×104 Q. Further, the resistance value of the conductive member is set lower than a value where the conductive member is charged with static electricity, for example less than 1.0×109 Q, so the conductive member is not charged with high voltage static electricity. For this reason, the energy required for a discharge does not accumulate in this conductive member and accordingly noise due to static electricity can be suppressed.
