Title: Method and system for detecting leakage of distributing piping
Inventor: KURATA SAKUJI
IPC: E03B1/02
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a leakage detecting method for a distributing pipe to be strong on noise and detect leakage of water with higher precision than precision of a conventional method, and specifying a leakage position with high precision, and to provide a leakage detecting system to concentratedly monitor leakage of a plurality of distribution lines by using the detecting method. SOLUTION: Leakage noise detecting sensors S1 and S2 are disposed at the two ends of a detecting section set at the distribution pipe 1 of a distribution line. A sound in water from the sensors S1 and S2 is A/D-converted by an A/D conversion sensor 3 and inputted to a leakage noise data processing device 6 through a telephone line 5. The waveform of an underwater sound is classified at each frequency by a data processing device 6 by using a plurality of filters and through synthesis of waveforms, it is decided whether a leakage water sound is present. In this case, when it is decided that it is a leakage water sound, this position is displayed at a leakage detecting displaying device 7, and when occasion demands, an estimated value of a leakage water quantity is displayed and printed by a printer 8.

Title: Distribution constant line-type filter
Inventor: SASAKI YUTAKA
IPC: H01P1/203
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To reduce the loss of distribution constant line-type resonators and the insertion loss of a filter and to prevent a filter size from being enlarged by setting the line width of a distribution constant line ground-side to be wider than an opening-side and reducing line resistance of the ground-side of high-frequency current. SOLUTION: A signal from an input distribution constant line 7 resonates only around a target frequency through connection capacity 5 and signals except for the signal are inputted to the resonance circuits of the reflecting distribution constant line-type resonators 2 and 3. The resonated signals are outputted from an output distribution constant line 8 through a connection capacity 6. One end of the respective constant line-type resonators 2 and 3 is opened, and the other end is grounded. Much high-frequency radio waves flowing in the distribution constant line exist in the ground-side, and they are reduced toward the opening-side. Thus, line resistance on the ground-side, where much high frequency current flow, can be reduced by setting the line width of the ground-side to be wider than the line width of the opening-side.
