Title: Redundant circuit for optical submarine repeater
Inventor: TAKAHASHI TSUTOMU
IPC: H04B10/07
Filed: 1989-12-15
Abstract: PURPOSE:To reduce the number of auxiliary optical output circuits by constituting the redundancy of an optical output circuit with only one auxiliary circuit at a minimum and using the arbitrary optical output circuit while being switched by selective switching at the time of a fault. CONSTITUTION:An optical submarine repeater 1 builds in three regenerators composed of two regenerators 7a and one regenerator 7b and the number of optical output circuits 5 is larger than that of systems in a transmission line only by one. In the optical submarine repeater 1, an electric switch circuit 4 is provided as well to receive the output of a 3R circuit 3 of three lines and to connect this output to three circuits selected out of the four optical output circuits 5 and an optical switch circuit 6 is provided to selectively connect the three outputs of the four optical output circuits 5 to three optical fiber cables 11. When generating the fault, the optical output circuits 5 are arbitrarily switched by combining the electric switch circuit 4 and the optical switch circuit 6. Thus, the number of the optical output circuits 5 required for securing redundancy is suppressed.

Title: Load control system
Inventor: NAKATANI HIROSHIGE
IPC: H04Q9/00
Filed: 1990-11-27
Abstract: PURPOSE:To reduce the burden of a master unit by providing a timer for the timer control of a load and a display device for displaying the operation of the timer at a switch terminal. CONSTITUTION:When an external input switch S1 is operated in the load control system using a time division multiple transmission system, a control circuit 4 of a switch terminal B1 starts a timer 1 and starts turning a display 3 on/off. Thus, it is not necessary for the master unit to manage time for the timer control of the load or to control the ON/OFF of the display device for displaying the timer operation, and the burden of the master unit can be reduced. Further, it is preferable for the control circuit 4 to vary the on/off cycle of the display device 3 corresponding to the remaining time of the timer 1.
