摘要:
The present invention provides a repeater which automatically closes a dynamically opened port in accordance with prior setting, the repeater including: a port mapping table where a global IP address and an external port number, or an external port number on the Internet is associated with a local IP address and an internal port number of a terminal connected to a LAN; a control unit which, receiving a communications packet to which an external port number is specified, converts the external port number to an internal port number based on the port mapping table and transfers the internal port number to the LAN; a timer unit which counts the unoccupied time of the port after transferring a communications packet to which an external port number is specified; and a port management unit which checks whether the registered machine is present on the LAN and in case it is absent, deletes registration concerning the external port number from the port mapping table.

The present invention has an object to provide a relay device capable of performing dynamic port forward setting to open a port even if performing a connection in two stages and being connected to a network and a port forward setting method, and relates to a router for relaying a data packet which has such a structure as to comprise a control portion for giving a port forward setting request to an upper router 2 to perform the port forward setting of the upper router 2 and to relate port forward setting for a CP4 to port forward setting of a router upon receipt of the port forward setting request from the CP4 when a WAN side I/F portion is connected to an internet 1 through the upper router 2 and a LAN side I/F portion is connected to the CP4.

In a mobile device that can be switched between the portrait orientation and the landscape orientation, improvements are made so that a swivel casing can be supported stably while maintaining a good appearance of the mobile device. A swivel casing 3 of a mobile phone 1 is supported by a swivel support mechanism 10 so that it swivels from the portrait orientation to the landscape orientation or from the landscape orientation to the portrait orientation. A movement opening 25 for allowing the swivel support mechanism 10 to move therethrough is formed in a middle portion in a thickness direction of a side surface of the swivel casing 3.

High-frequency circuit components are disclosed in which parasitic capacitance between a high-frequency circuit element and a substrate is reduced and mechanical strength is improved. An exemplary component has a conductive substrate, a coil as the high-frequency circuit-element, a mounting board including a thin dielectric film on which the coil is mounted, and a support board that couples the mounting board to the substrate. The mounting board is coupled so that it floats relative to the substrate as a result of deliberate warping of the support board.

A gateway apparatus obtains IPv6 address information assigned to a monitoring camera by using a camera search unit and assigns a host name to the monitoring camera by using a camera information registration unit, the monitoring camera being connected to the gateway apparatus via a network. The gateway apparatus stores the host name and the IPv6 address of the monitoring camera in a camera information database, and stores the host name and the IPv6 address of the monitoring camera on a DDNS server in association with the host name assigned to the gateway apparatus.

A ticket processing terminal device includes a hopper to store medium that is to become prescribed tickets, a separation and pick-up section for separating and picking up one sheet of medium at a time from the hopper, a stacker to store those of the tickets inserted through the insertion opening which are replaced by the medium, a print section for printing on the ticket that has been inserted through the insertion opening or the medium picked up from the hopper, and is to be discharged through a discharge opening, a transport path to transport the tickets and medium between the above mentioned component elements, and a ticket information reader for magnetically or optically reading the information that has been given to the ticket, and a magnetic write section disposed along the transport path for writing, erasing or rewriting on the magnetic stripe if the ticket inserted through the insertion opening or the medium picked up from the hopper has such a magnetic stripe. The terminal device can accept a plurality of tickets, temporarily store them, and subsequently reissue either modified versions of less than the original number inserted or a new medium to replace the plural inserted tickets.

A card read/write device comprises a frame having a card insertion opening, electrode terminals arranged according to electrodes provided on a card, and a disconnection mechanism for moving the electrode terminals to and away from the electrodes of the card. The disconnection mechanism is rotatably mounted on the frame and comprises contact members having the electrode terminals, transfer levers interlocked with insertion of the card for permitting the electrode terminals to contact the electrodes of the card, and a spring for urging the contact members in the direction to move the contact members away from the card.

摘要:
Magnetic recording media are provided having separately textured data and read/write head landing zones. Separating these zones on the recording surface allows independent optimization of the topology to maximize both recording characteristics and mechanical durability. The landing or contact start stop zone has an average surface roughness greater than that of the data zone. Preferably, a transition zone extends between the contact start stop zone and the data zone, the transition zone varying between the two in average surface roughness. Preferably, the contact start stop zone is textured first, followed by the data zone, thereby ensuring uniform stiction performance. Texture machines for producing such zone texturing and texturing methods are also provided.
