20090016378 | Packet transfer apparatus - A packet transfer apparatus connects two networks of different protocols. The packet transfer apparatus, connected to a first communication network and a second communication network, performs the steps of: storing first destination correspondence information; receiving a packet of the first communication protocol; based on the first destination correspondence information, determining destination information of a packet of the second communication protocol corresponding to destination information of the received packet of the first communication protocol; generating the header of the packet of the second communication protocol, based on the determined destination information of the packet of the second communication protocol; converting the received one or more packets of the first communication protocol into one or more packets of the third communication protocol; and adding the generated header of the packet of the second communication protocol to the packets of the third communication protocol. | 01-15-2009 |

20100021161 | PON SYSTEM - Disclosed herewith is a PON system and a bandwidth controlling method capable of controlling congestion with use of an upstream bandwidth in a PON section efficiently when congestion occurs in a gateway (GW) connected to an OLT. An OLT connected to a plurality of ONUs through a passive optical network (PON) and to a gateway (GW) through a communication line, when receiving a congestion occurrence notice indicating a congestion occurred output number from a GW, identifies the identifier of the ONU that is using a GW output line having the congestion output port number and shifts the bandwidth controlling of the PON section in a normal mode for allocating a bandwidth to each ONU normally to that in a bandwidth suppression mode for allocating a congestion time allowable bandwidth that is less than the current bandwidth to the ONU having the identified ONU identifier and a bandwidth to each of other ONUs according to its transmission queue length. | 01-28-2010 |
20100135162 | TRANSMISSION APPARATUS AND TRANSMISSION SYSTEM - A link aggregation function and maintenance function by MPLS OAM. Identical entry information is stored in plural circuits IF which perform a LA setting. In this way, multiplexing to the same LSP is possible even with different IF. The first network IF is assumed to be OAM ACT, and the second network IF is set to OAM SBY (SBY). OAM frame insertion is performed only by an OAM ACT port. In this way, in an opposite MPLS transmission apparatus, it is possible to prevent CV frame reception above a specified number of frames. Further, a switch forwarding table is set to forward frames from the network side to the first network IF of OAM ACT. The second network IF which was set to OAM SBY does not perform fault detection by CV reception. In this way, incorrect detection of faults due to non-reception of OAM can be prevented. | 06-03-2010 |
20110096794 | Packet transfer apparatus - A packet transfer apparatus connects two networks of different protocols. The packet transfer apparatus, connected to a first communication network and a second communication network, performs the steps of: storing first destination correspondence information; receiving a packet of the first communication protocol; based on the first destination correspondence information, determining destination information of a packet of the second communication protocol corresponding to destination information of the received packet of the first communication protocol; generating the header of the packet of the second communication protocol, based on the determined destination information of the packet of the second communication protocol; converting the received one or more packets of the first communication protocol into one or more packets of the third communication protocol; and adding the generated header of the packet of the second communication protocol to the packets of the third communication protocol. | 04-28-2011 |
20110268435 | COMMUNICATION SYSTEM, SUBSCRIBER ACCOMMODATING APPARATUS AND COMMUNICATION METHOD - Switching process at the occurrence of a path trouble is performed more quickly to reduce the number of packet discards during a traffic transition from a currently used system path to a standby system path within a section to be protected. An OLT ( | 11-03-2011 |

20140161711 | FLAME-RESISTANT HEAT TREATMENT FURNACE - A furnace to flame-resistantly treat a precursor fiber strand by sending hot air to a heat treatment chamber through a hot air blowing nozzle in a direction parallel to a running direction of the strand is provided. The hot air passes through a porous plate and a rectifying member satisfying the following conditions: (1) AB≧4.0; (2) 0.15≦α≦0.35; (3) 0≦B−d≦20; and (4) 80% or more of the area of one opening of the porous plate when facing surfaces of the porous plate and the rectifying member overlap is included in one opening of the rectifying member, where A is the rectifying member hot air passage distance (mm), B is a horizontal maximum distance (mm) of one opening of the rectifying member, α is a rate of hole area of the porous plate, and d is the porous plate equivalent diameter (mm). | 06-12-2014 |
20150299909 | Horizontal Heat Treatment Device - A horizontal heat treatment device continuously subjects an untreated continuous flat object to heat treatment while horizontally transferring the untreated object within a heat treatment chamber. Seal chambers are interconnected to the untreated-object loading opening and treated-object unloading opening of the heat treatment chamber. A passage is connected to an opening of each of the seal chambers, the opening located on the side opposite the heat treatment chamber. The untreated-object passage loading opening interconnected to the untreated-object seal chamber loading opening and the treated-object passage unloading opening interconnected to the treated-object seal chamber unloading opening are the untreated-object loading opening and treated-object unloading opening of the heat treatment device.
