    • A mechanical mounting system for a zoom objective having provision for close-up operation includes an actuator serving to perform both focusing and zooming operations as it is turned and axially moved respectively. When the actuator is axially moved to the wide angle position and when it is turned to the lower limit of the focusing range, a drive connection between the actuator and a camming cylinder for the zoom and close-up control is established even in the transverse direction. Upon transverse movement of the actuator beyond the focusing range, the camming cylinder is turned to axially move the variator forwardly while the compensator remains stationary in the wide angle position thereby effecting a close-up operation.

    • A zoom lens assembly having a mechanical mounting system for the lens components thereof wherein zooming, focusing and closeup operations may be selectively performed by operation of a single actuator member. A lens barrel is provided within which a variator lens and a compensator lens are movably fitted with an intermediate sleeve being fitted on the barrel member and arranged to move axially in unison with the actuator member and to be rotatable relative thereto, a drive connection being provided between the actuator member and the variator lens holder member with motion transmission occurring between the intermediate sleeve and the compensator lens holder member. Focusing operation is effected by rotation of the actuator member and by axial movement of the actuator member, the compensator lens and the variator lens are axially moved with a compensation effect being maintained for the optical system by relative movement between the variator lens and the compensator lens.

    • A device in a line part from a LAN to a WAN includes a plurality of cards which includes a TCP converter relaying two TCP communications. The TCP converter exchanges the number of connections in which data transmission is in progress and the number of connections in which data reception is in progress between TCP converters, receives the total number of connections in which data reception is in progress in an opposite device and an access line bandwidth to a WAN from the opposite device for each TCP connection. A control bandwidth is determined on the basis of the retransmission ratio of data, the total number of connections in which data transmission is in progress and an access line bandwidth to the WAN, and the total number of connections in which data reception is in progress and an access line bandwidth to the WAN of which the opposite device notifies.

    • An object of the present invention is to provide a communication apparatus and a data distribution system which are fast in the response speed of data distribution and require less space and less electric power. The present invention provides a communication apparatus which is provided with a broadband transmission module for reproduction by which a constant amount of data is transmitted from an initial data transmission server in a broad band immediately after a client instructs to distribute the data and then, subsequent data is transmitted from a subsequent data transmission server in a normal band, a load balancing module (a module for dispersing a distribution request from a client among plural servers accumulating the same file) and a file dispersion access module (a module for sorting a distribution request from a client into a server storing the file corresponding to the distribution request), and which includes a server arraying module for directly arraying plural servers without using a disk array to integrate resources of the servers into one. Further, the present invention provides a VOD distribution system including the communication apparatus and the plural servers.

    • A communication device, an illegal communication protection device, and network system for providing protection from illegal communications. A communication device is connected to a network, for receiving packets sent and received over networks, and transmitting packets based on the packet destination, includes a control unit, and a storage unit for storing a routing table that stores the destination information. When there is a connection request from a packet that was received, the control unit stores the transmit source address of that packet and the line number where that packet was received, into a routing table, and where there is no connection request from the received packet, the control unit refers to the routing table, acquires the line number linked to an address matching the destination address of that packet, and sends the applicable packet via the acquired line number.
