Title: Loop island protection system for submarine transmission system
Inventor: ARAKI HIROFUMI
IPC: H04B10/291
Filed: 1991-09-11
Abstract: PURPOSE:To realize a system that can prevent such a case where a submarine repeater cannot be controlled by both end offices on the land and is isolated. CONSTITUTION:A command transmitter 1 is provided at the end offices A and B on the land to transmit the commands to each submarine repeater in a fixed cycle for identification of the loop islands together with a command detector 2. If the detector 2 of a certain repeater does not detect the loop island identification commands received from the transmitters of both offices A and B while each repeater is receiving the loop-back commands from the offices A and B, the loop island state of the relevant repeater is recognized and the switch is reset to the loop backs L1 and L2 of the normal inputs Si1 and Si2 of the repeater. Then a timer 3 starts to count the time when the loop back instructions SV1 and SV2 are received by each repeater from the offices A and B and then produces the pulses at each fixed time to cancel the switch to the normal input loop back of its own repeater station.

Title: Method and device for designing circuit
Inventor: SATO KENICHI
IPC: G06F17/50
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To enable a delay buffer to be inserted uselessly and automatically obtain an insertion position eliminating the need to extend the delay time of a critical path by determining the insertion position in consideration of the delay of other paths passing the insertion position when a logic element is inserted. SOLUTION: The circuit designing device 1 reads hold time violating path information in an insertion position determination part 2 for the logic element and stores its set. Then a circuit description represented in characters are read in and the delay quantities of respective paths are analyzed to obtain a maximum delay time. Then a parameter is set to 1 and it is decided whether the parameter is larger than the number of the elements of a hold time violating path; when an affirmative result is obtained, the insertion position determination part 2 outputs a buffer insertion position result generated as to all paths and finishes the process.  Unless the affirmative result can be obtained, it is confirmed whether or not respective paths corresponding to the parameter violates the hold time and if the time is violated, the most effective position for the improvement of the hold time violation is found.
