CONSTITUTION:It is assumed that the branch ratios of two optical fiber branching circuits 3 are set as 1:x, and 1:y. A light amplifier 12 has light amplification degree of 1/xy, that is the inverse number of the product (xy) of the branch ratios, and the amplification degree possible to compensate the difference of loss between optical fibers 1-A and 1-C. And the degree of coupling of two variable coupling connection parts 5-1 and 5-2 are synchronized and changed by a signal from a controller 13. The degree of coupling of the variable coupling connection part 5-1 is reduced, and adversely, that of the variable coupling connection part 5-2 is increased, then, branching loss is compensated by the amplifier. The light output from an optical fiber 1-2 becomes the sum of the light output from the optical fiber 1-A, and the light output from the optical fiber 1-C, then it is regulated in a time aspect. By reducing the degree of coupling of the variable coupling connection part 5-1, and increasing that of the variable coupling connection part 5-2, keeping the rgulated level of the light output, switching from the optical fiber 1-A to the optical fiber 1-C can be performed.

Title: Transmission line control system for double loop-type communication equipment
IPC: H04L12/42
Filed: 1992-03-19
Abstract: PURPOSE:To obtain the transmission line control system for a double loop LAN where a communication line is secured even between nodes which lose the communication line with a master node MN by fault occurrence. CONSTITUTION:When a fault occurs in the transmission line 10 between SN1 and SN2, a node device SN2 is permitted to autonomously execute an operation for transmitting fault information which informs of fault occurrence to the adjacent node device SN1 at a side where the fault occurs and a loop back operation. The node device SN1 which receives the fault information is also permitted to autonomously execute the loop back operation. Thereby, the nodes SN1 and SN2 being adjacent to the fault respectively execute the loop back operation so that the ring-shape transmission line which evades the fault is generated. The loop control is completed in a short time, since MN is not made to interpose.

Title: Anchoring of marine structure
Inventor: YAMAMOTO SHIYUUHEI
IPC: B63B21/00
Filed: 1978-07-27
Abstract: PURPOSE: To reduce the dynamic load upon an anchorage line for connecting a marine structure to a dolphin or the like, by hanging a horizontal resistance plate under water with a rope coupled to the intermediate part of the anchorage line.  
     CONSTITUTION: The marine structure 1 floats on the sea. The dolphin 2 is set up on the bottom of the sea so that the top of the dolphine is located above the surface of the sea. The anchorage line 5 made of rope or chain is coupled to the marine structure 1 and the dolf dolphin 2 to anchor the structure in a prescribed position on the sea. The horizontal resistance plate 7 is hung under the surface 4 of the sea with the rope 6 from the intermediate part of the anchorage line 5. When an external force A is applied to the marine structure 1 oppositely to the anchoring direction, the anchorage line 5 is tensioned to lift the resistance plate 7. The external force is thus opposed by the fluid resistance which acts on the resistance plate. This results in reducing the increase in the tension of the anchorage line 5.
