摘要： An optical distribution network system includes an OLT; a plurality of ONUs; a first optical network and a second optical network, one of which connects the OLT with the plurality of ONUs; and a bandwidth controller. The bandwidth controller apportions the plurality of ONUs between the first optical network and the second optical network, assigns a predetermined transmission bandwidth to each of the plurality of ONUs, and accepts a bandwidth change of the transmission bandwidth. It solves a problem of a conventional optical distribution network system in that the maximum bandwidth available by DBA (dynamic bandwidth assignment) is equal to the total transmission bandwidth of working side minus the sum total of the minimum cell rates of the ONUs, and hence it cannot secure a large usable bandwidth for DBA, when congestion of bandwidth increase takes place among the plurality of ONUs.

摘要： In a communications system in which a plurality of subscriber apparatuses and a station apparatus are connected to the same transmission channel for bidirectional communication, a bandwidth allocated in a direction from subscriber apparatuses to a station apparatus is dynamically updated. More specifically, a bandwidth usage rate is calculated from a bandwidth allocated in a updating period and a bandwidth actually used in the updating period. A bandwidth to be allocated in a subsequent period is determined based on the bandwidth usage rate thus calculated. With this construction, the station apparatus is capable of allocating the bandwidth required by the subscriber apparatuses or subscriber terminal apparatuses so that the bandwidth is efficiently used.

摘要： Provided is a method for producing an active material for a lithium secondary battery to enable efficient removal of iron impurities, which would become a problem in production of an active material for a lithium secondary battery, and attain a high quality. The method includes removing iron impurities in an active material for a lithium secondary battery by means of magnetic force. With this method, use of a magnetic force-generating device within a recess portion, which composes at least one part of the recess portion, enables efficient removal of only iron impurities. Thus, it is expected that a voltage drop caused by dissolution of iron compounds, i.e. impurities in a positive electrode, and their migration to a negative electrode in a battery, and decreases in charge and discharge efficiencies and a voltage drop owing to precipitation of lithium can be suppressed.
