Title: Data transmission device, and method and program for controlling transmission rate
Inventor: SANJEEWA RANATUNGA VIJITHA
IPC: H04L12/841
Filed: 2008-04-25
Abstract: <P>PROBLEM TO BE SOLVED: To properly control the transmission rate during a multi-stream transmission.  <P>SOLUTION: A rate controlling section 206 of a data transmission device 200 performs statistical processing (averaging processing) on packet loss rates and RTTs of streams supplied from RTCP communication sections 204a and 204b. Then, the rate controlling section 206 calculates an overall transmission rate by, for example, a TCP throughput formula in IETF RFC3448, using the results of the statistical processing, that is, an average value of the packet loss rates and an average value of the RTTs of the streams supplied. Thereafter, the rate controlling section 206 sets a transmission rate for each stream based on the overall transmission rate and an allocation ratio of each stream. Since the transmission rate is set for each stream based on the allocation ratio after calculating the overall transmission rate, an overall traffic to be caused to flow in an network can be controlled and thereby congestion in the network can be controlled. Moreover, the ratio of transmission rates of the streams can be maintained.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a stem which can utilize in writing utensils such as a pencil used by shaving the stem covering a lead material therewith and in cosmetics such as an eye shadow and the extent of the shaving force of which can be modulated arbitrarily.  <P>SOLUTION: The stem 2 covering the lead material is formed with a resin molded body made of a thermoplastic synthetic resin 21 blended with wood powder 22 and thermally expansible micro-capsules 23. As the foam molding is performed by blending the thermally expansible micro-capsules 23, the foaming gas generated from a foaming agent stays within the cells of the micro-capsules, resulting in causing no change of expansion ratio through escaping of the foaming gas from the thermoplastic resin 21 and easily molding the resin molded body so as to have a predetermined expansion ratio. Thus, the lightly and slashingly shaveable hardness of the stem can be modulated even under the condition that the rigid thermoplastic resin 21 is employed in the stem.  <P>COPYRIGHT: (C)2010,JPO&INPIT
