Abstract: A display device is equipped with a panel having a common electrode layer to which a voltage changing at a fixed frequency is applied and a tabular member which is arranged at a fixed gap from said panel. A voltage which is changed in synchronization with the change of a voltage which is applied to the common electrode layer is applied, and an electrode layer which is arranged so as to be nearly parallel to the fore-mentioned tabular member and the fore-mentioned panel is provided.

Abstract: In a routing control apparatus and method for a composite network, a decision is automatically made as to whether a connection to a public telephone network via a leased line is allowed, by examining the dial information entered from a calling party and judging the communications applicable to the receiving node, the type of communication requested, and other factors. A connection judging unit extracts, from the dial information entered by the calling party, a node identifier CC for specifying the receiving node and a connecting type identifier V/F for directing the initiation of judgment as to whether a connection to a public network via a leased line is allowed and for providing a parameter for determining the type of communication requested, and which judges, based on the extracted identifiers CC and V/F, whether a connection to a public telephone network accommodating the called party is allowed via a leased line destined for a receiving node.
