IPC: H04L12/28
Filed: 1994-10-04
Abstract: PURPOSE: To suppress the number of times of master clock node switching during system operations to the minimum by periodically changing a node most stably operated at that time point into the master clock node among the nodes on the same LAN. CONSTITUTION: A monitoring part 6 collects the fault information of a transmission line IF part 1, multiplex part 2, terminal IF part 3, control part 4 and power source part 5 and reports it to a LAN managing device 8. The priority arithmetic means of the device 8 collects the fault information generated at these plural node circles 1, 2, 3... and find the priority of respective nodes by using a statistical method. For example, the degrees of instability for respective nodes are calculated for each node from the number of times of fault generation and the degree of importance for that fault in the communication system. Then, the decision of priority is started from the node with the least degree of instability, namely, from the most stable node and the change instruction of the master clock node and the priority data are transmitted to the respective nodes.  Since each node performs an automatic change corresponding to the received priority data so that the most preferential node can be the master clock node, the number of times of node switching is suppressed to the minimum.

Filed: 1983-12-20
Abstract: PURPOSE:To improve measurement precision by correcting the film thickness of one metallic film of a metallic plate composed of two metallic layers measured by an eddy current type film thickness measuring instrument according to variation in the overall film thickness. CONSTITUTION:The thickness T of the metallic plate 11 is measured by a sensor 16 for ultrasonic film thickness measurement to obtain an electric signal corresponding to variation in T from the ultrasonic film thickness measuring instrument 18. A detection coil 14, on the other hand, generates an eddy current in the metallic plate 11 by a high frequency power source 21. If the lower metallic film 13 varies in thickness B and the eddy current increases or decreases, the impedance of the detection coil 14 varies. This eddy current, however, operates on a compensating coil 15 and the output of a bridge circuit 20, therefore, corresponds to the impedance variation of the detection coil 14. This impedance variation is passed through an amplifier 22 and a phase detector 23 and then detected as a signal proportional to the reactance component and resistance component of the impedance.
