Title: Video tone circuit
Inventor: OSAWA IKUO
IPC: H04N5/208
Filed: 1989-12-15
Abstract: PURPOSE:To automatically compensate the excess emphasis of a video tone by limiting the amplitude of a level when the level of a secondary differentiating signal to be obtained from a VCA(voltage controlled amplifier) exceeds a prescribed level and superimposing the signal to an original luminance signal. CONSTITUTION:When the luminance signal expressed by (a) in a figure is impressed to an input terminal 1, the luminance signal is passed through a secondary differentiation circuit, which is composed of first and second differentiation circuits 2 and 3, and a VCA 4 and the secondary differentiating signal shown by (b) in the figure is generated. For this secondary differentiating signal, the amplitude is limited by a limiter 7 like a dashed line (c) in the figure and the signal is superimposed with the luminance signal from the input terminal 1 by a subtracting circuit 5. Therefore, a luminance signal (c) in the figure can be obtained at an output terminal 8 of the subtracting circuit 5. The change of the signal to be generated at time t1 and t2 is made small in comparison with a case not to limit the amplitude and the excess emphasis is corrected. Thus, the excess emphasis of the video tone can be automatically compensated.

Title: Method for recovering sludge of river cleaning equipment and sludge retension hopper
Inventor: NOMURA KAZUHIRO
IPC: C02F3/06
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To recover easily sludge deposited solidified on a slant surface of a hopper by a method wherein a fluid is ejected uniformly upward from an upper part peripheral edge of a sludge retention hopper, and a water current in the sludge retention hopper is made a circulating current which ascends in a peripheral edge part and descends in a central part. SOLUTION: A circulating current which ascends on a peripheral edge and descends near a center is generated in a hopper 10 by air ejected from an aeration pipe 11 provided peripherally on an upper part peripheral edge of a hopper 10. For the circulating current, its flow rate is fastest in a peripheral edge part of the hopper 10 by being urged by air ejected from the aeration pipe 11, and becomes slow near a center having no urge of air. Therefore, sludge becomes more easy to deposite near the center, and since river water in the hopper 10 is always circulated, deposited sludge is also difficult to generate compaction by consolidation. Then, it is very seldom that sludge is adhered onto a slanting surface of the hopper 10, and discharge of the sludge becomes very easy.
