Title: Method for deciding echo connection coefficient and echo delay time in bidirectional electric communication system
Inventor: WALKER MICHAEL
IPC: H04M1/58
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To compensate an echo generated in a bi-directional electric communication system by analyzing a conversation and using a method for deciding a state whose probability for erroneously evaluating a connection coefficient between transmission routes and echo delay time is considerably low and a time segment. SOLUTION: Information is exchanged between a local subscriber X and a subscriber Y at the remote end of a transmission link. An echo suppressor 5 is allocated to one subscriber between the subscribers X and Y and the parameter of the echo suppressor 5 is set in accordance with an echo connection coefficient CF and echo delay time (i) by a control circuit 6. A state showing the feature of information and a time segment are decided while information is exchanged between the local subscriber X and the subscriber Y at the remote end of the transmission link. Then, the reliability of the measurement of the echo connection coefficient CF and that of echo delay time (i) depends on the decision.

Title: Method and device for improving lean oxygen layer in sea region
Inventor: WADA YOSHIMASA
IPC: A01K63/04
Filed: 1986-12-11
Abstract: PURPOSE:To accelerate the propagation and living of aquatic product resources by forming circulation flow between the lean oxygen sea water region of the bottom layer of the sea region and the rich oxygen sea water region of the front layer thereof to mix the sea water in the two sea region layers, thereby eliminating the lean oxygen water lumps. CONSTITUTION:The rich oxygen sea water in the front layer beta of the sea region is fed to the lean oxygen sea water region of the bottom layer alpha of the sea region and is ejected therefrom to generate upward gushing flow J in the sea region so that the circulation flow is generated between the front layers beta of the rich oxygen sea water region to stir and mix the bottom layer beta and the front layer alpha of the sea regions. Associated buoyancy to the ejected rich oxygen sea water is energized by previously incorporating fine air bubbles into the rich oxygen sea water prior to the feeding or ejecting the fine air bubbles O from the lower side of the rich oxygen sea water injected laterally into the lean oxygen sea water region, by which the pressure increasing force of the upward gushing water is energized and accelerated. As a result, the lean oxygen water lump layer to be formed in the bottom layer is eliminated and the environment of the sea region is improved, by which the propagation and living of the aquatic product resources meeting the areas and seasons are accelerated.
