A switch apparatus includes: a plurality of ports; a VLAN setting management unit storing entries, in each of which VLAN information and at least one of the plurality of ports are associated with each other, and adding or updating, if an entry corresponding to a combination of VLAN information included in a packet received from a port and the reception port of the packet is not stored, a corresponding entry for the received packet; and a functional unit notifying a predetermined control apparatus of an added or updated content of the entry.

Switch apparatus, VLAN setting management method, and program

In the present situation, a switch cannot identify inner tag data (VLAN ID data before QinQed in the input of OF-NW) given to each of packets which flow in an open flow network (OF-NW). Therefore, OF-NW composed only one VLAN cannot handle a plurality of VLANs. Specifically, a controller handles a plurality of VLANs in the OF-NW in which there is only one VLAN, by mapping the inner tag data given to the packets which flow through the OF-NW, and flow cookie data showing the flow entry corresponding to the packets which flow through the OF-NW. Specifically, the flow flowing into the OF-NW is transferred from the switch to the controller, and the controller learns VLAN ID data in the input of the OF-NW, and handles the plurality of VLANs by mapping this VLAN ID and the flow cookie data showing the flow entry corresponding to the packet in the OF-NW.

Network system and VLAN tag data acquiring method

A communication system includes a communication apparatus that processes a packet according to control information set by a control apparatus; a first control apparatus that controls the communication apparatus by setting the control information in the communication apparatus; and a second control apparatus that operates in concert with the first control apparatus. The first control apparatus transmits information necessary for interoperation between the first and second control apparatuses to the second control apparatus via the communication apparatus.

Disc brake

In the pushing anchor type disc brake device, reduction of noise and prevention of uneven wear can be accomplished especially in the brake device in which brake torque of the outer pad is transmitted via the caliper. In the disc brake device, the caliper is guided by a pair of guide pins composed of a main pin and a sub-pin. In order to transmit the brake torque of the outer pad via the caliper and the main pin, the back plate of the outer pad and the caliper are engaged with each other by engaging a protrusion with a recess, wherein the engagement is conducted at a plurality of portions in the circumferential direction of the rotor, so that the brake torque can be transmitted from the outer pad to the caliper. The main pin is arranged on the rotor run-out side, so that a pushing anchor structure can be formed. A pair of guide pins and guide holes of the support member which engage with the pair of guide pins stride the rotor and extend exceeding a facing section where the rotor faces the outer pad. The main pin is arranged on the rotor run-out side. Brake torque on the outer pad side is transmitted by the protrusion and recess engaging section arranged on the rotor run-out side.

The present invention relates to a tape transport apparatus and a tape introduction method for forming a magnetic tape into an endless loop by splicing a leader tape to the magnetic tape and running such endless-loop magnetic tape therein. When an endless loop is shaped by splicing the magnetic tape and the leader tape to each other, the starting (front) end of the magnetic tape is drawn out to a splicing position while the front (fore) end of the leader tape is also brought thereto and, after the respective ends are spliced together, the endless loop is moved until the spliced portion between the magnetic tape and the leader tape is shifted to the splicing position for the leader tape. The starting front end of the magnetic tape led by such leader tape is then spliced to the terminal rear end of the magnetic tape, so that an endless loop is formed automatically without the necessity of the performance of operation by hand upon the magnetic tape.

Tape transport apparatus and method of introducing tape thereto

A magnetic tape container for use in combination with a magnetic tape duplicating apparatus in which a long, endless, master magnetic tape is circulated to produce many duplicates of the master magnetic tape. The magnetic tape container has most of the long, endless, master magnetic tape in a zigzag fashion for circulating the master magnetic tape through the magnetic tape duplicating apparatus. The magnetic tape container is comprised of a tape case, a feed mechanism having a capstan disposed near the entrance of the tape case, a pinch roller mounted for free rotation on a swing lever being brought into contact with the capstan or retracted from the capstan, provided with at least one annular air guide groove in the circumference thereof. A first tape guide is disposed near the capstan, and a second tape guide is disposed near the pinch roller opposite to the first tape guide to form a gap between the first tape guide and the second tape guide. An air blowing member is disposed near the pinch roller to blow air toward a gap between the second tape guide and the pinch roller so that air blown by the air blowing member flows through the gap between the pinch roller and the second guide and through the annular air guide groove of the pinch roller to impinge on the magnetic tape to separate it from the pinch roller, so that the surface of the magnetic tape facing the pinch roller is not abraded by the pinch roller.
