Abstract: A communication terminal apparatus (separate type portable telephone) separated into a first communication apparatus (parent device) and a second communication apparatus (child device), the first communication apparatus and the second communication apparatus in a separated state being wirelessly connected through direct communication. The communication terminal apparatus includes a joining detecting unit and a power supply control unit. The joining detecting unit detects joining between the first communication apparatus and the second communication apparatus. The power supply control unit performs control for conforming a power control state of the second communication apparatus to a power control state of the first communication apparatus if the first communication apparatus and the second communication apparatus are joined while the power control states are different between the first communication apparatus and the second communication apparatus.

Abstract: A mobile terminal device including a first housing, a second housing, the device having multiple configurations, including a first configuration in which the second housing is closed with respect to the first housing, a second configuration in which the second housing is slid relative to the first housing from the first configuration, and a third configuration in which the first housing is separated from the second housing, and a first input key is provided on the first housing, and is covered with the second housing in the first and second configurations and is exposed in the third configuration.

Abstract: A portable terminal apparatus includes a first enclosure, a second enclosure, and a control unit. The second enclosure takes modified forms including a first form and a second form. The second enclosure is closed over the first enclosure in the case of the first form. The second enclosure is separated from the first enclosure in the case of the second form. In the case of the first form, the control unit controls communication to be performed between the first enclosure and the second enclosure via a contact between the first enclosure and the second enclosure. In the case of the second form, the control unit controls communication to be performed between the first enclosure and the second enclosure by a radio communication unit.

Abstract: A system for controlling topology views for operators in network management includes a data-storage unit which stores data of a base topology view, a security-management unit which controls access-authorization information with respect to each of the operators, the access-authorization information for a given operator defining network elements accessible by the given operator, and a topology-view-management unit which generates data of a dependent topology view by making a partial copy of the data of the base topology view only with respect to the network elements accessible by the given operator, thereby providing the dependent topology view to be presented to the given operator.
