Abstract: A method and a system for multiplexing voice packets without delay variation even if the number of multiplexed channels is increased, wherein a packet buffering unit receives compressed voice data, and stores voice data groups during voice activity intervals in each channel as talk; a scheduling FIFO block sequentially stores the channel numbers of a predetermined number of multiplexed channels which are read according to priority over the other channels, thereby controlling reading contention. A write decision block controls writing of talk spurts in the buffer areas of the respective channels in a packet buffering unit and also controls writing of the channel numbers in the scheduling FIFO block. A scheduling FIFO controller selects channel numbers from the scheduling FIFO block and a read decision block outputs voice packets by controlling the multiplexing sequence of talk spurts of the selected channel numbers.

Abstract: The present invention provides a rolling bearing in which an oxide layer of an iron/chromium oxide series is formed at a thickness of from 1 to 1000 nm to at least one of raceway surfaces of bearing rings or rolling contact surfaces of rolling elements and a manufacturing method thereof. The oxide layer can inhibit hydrogen formed by decomposition of water incorporated in the lubricants from intruding into the matrix of the bearing members, thereby preventing early peeling for the raceway surfaces of the bearing rings or the rolling contact surfaces of the rolling elements and, thus, greatly improving the rolling life. The oxide layer can be formed simply by merely tempering the bearing member and then applying a re-heating treatment in air at a temperature lower than the tempering temperature.
