  • Patent number: 6928069
    Abstract: A bandwidth management apparatus determines, when a call whose communication information is to be transmitted as a sequence of datagrams is assigned, a link to be used for transmitting the communication information, judges whether there exists a surplus bandwidth in sections of the determined link, and allocates the call to a bandwidth necessary for transmitting the communication information when the judgement result is true, and informs a node that is involved in call setup for the call about the judgement result. Also disclosed are an address resolution assistance apparatus that cooperates with the bandwidth management apparatus, a band managing method, and an address resolution assisting method which realize the respective apparatuses. In a network to which the invention is applied, good speech quality can be stably maintained irrespective of its configuration and scale.

  • Publication number: 20050099402
    Abstract: The touch panel has a structure such that a projection portion is provided on a second transparent substrate and a flexible printed-circuit board is bonded by thermocompression to the projection portion. By allowing width of a picture frame to be smaller in other portions than the projection portion, downsizing and a lighter weight of a touch panel-carrying apparatus can be attained. By bonding a sheet member such as a polarizing plate to a top face of the second transparent substrate excluding an area of the projection portion, stress to be applied from the sheet member to the thermocompression-bonding portion of the FPC is reduced and, therefore, electric connection stability of the FPC can be enhanced.
