Abstract: In an audio network system connecting a plurality of nodes in a ring form, a master node transmits a packet of frame data regularly every sampling cycle, such that the packet circulates through the nodes during the sampling cycle. The packet is provided with a plurality of regions for containing audio sample data in correspondence to a plurality of channels. A first node reads audio sample data from a particular region of the packet, which corresponds to a particular channel allocated to the first node, and stores the read audio sample data in a buffer. The first node acquires positional information indicating whether a second node which has written the audio sample data into the particular region is located upstream or downstream of the first node. The first node reads and outputs a previous one of the audio sample data from the buffer if the second node is located upstream of the first node, and outputs a current one of the audio sample data if the second node is located downstream of the first node.

Abstract: An audio network system allows any two nodes among a plurality of nodes to transmit and receive audio data to and from each other. The plurality of the nodes are connected in loop so as to allow transmission of the audio data in loop manner through the plurality of the nodes, and the transmission of the audio data is performed in one direction from an upstream node to a downstream node. One of the plurality of the nodes is set as a master node and the other nodes are set as slave nodes.

The packet has a specific data length and includes an audio data storage region divided into a plurality of blocks corresponding to a plurality of channels, such that each of the blocks stores audio data of the corresponding channel.

Abstract: A bearing with an oil film thickness measuring device in which sensor portions at distal ends of four common optical fibers are connected to sensor mounting portions formed at four positions in an axial direction of a bearing body. A lubricating oil containing a fluorescent agent is supplied to a sliding surface of the bearing body. A laser beam generated from a laser beam generator is branched into four beams, which are applied to an oil film on a sliding surface through each of sensor portions. Fluorescence generated by the fluorescent agent in the oil film, passing through a return-route optical fiber, is introduced into a photomultiplier tube, and is detected. Since the fluorescence intensity detected by the photomultiplier tube is proportional to the thickness of oil film, the absolute value of oil film thickness can be measured. In this case, the oil film thickness can be measured at four positions.
