20090201819 | Network System and Data Transfer Device - To prevent, in using a multicast DA in an OAM frame, an increase in the network bandwidth usage and in the load of node processing and a degradation of the network reliability caused by a frame being transmitted to all routes in a broadcast domain. A MAC address and other basic frame information and the MEGID are associated with each other, and the MEGID information is added to the OAM frame, and these information are transmitted from an edge node serving as an end point of an ME. In a relay node of the ME, a route control table used for OAM frame control is provided, and a filter is generated by snooping of the OAM frame. Furthermore, when the relay node does not support the OAM function, the MEGID is denoted by a VLAN tag and the route control is made using the snooping function of each VLAN tag. | 08-13-2009 |

20100232838 | DEVELOPING DEVICE AND IMAGE FORMING APPARATUS - A developing device includes a conveyance path, a conveyance member, a return path, and a pre-agitation region. The conveyance path conveys a toner while agitating the toner. The conveyance member has a rotational shaft, which is rotatably disposed along an upstream end to a downstream end of the conveyance path, and conveys the toner toward the downstream end due to rotation of the rotational shaft. The return path communicates with the downstream end and an intermediate portion of the conveyance path, thereby forming a circulation path, and returns the toner from the downstream end to the intermediate portion. The pre-agitation region is formed at the upstream end side, extending from the intermediate portion and outside the circulation path, and pre-agitates the toner to be conveyed to the circulation path. | 09-16-2010 |
