Title: Breakwater
Inventor: HONDA TORU
IPC: E02B3/06
Filed: 1985-07-24
Abstract: PURPOSE:To reduce the energy of waves with good efficiency by a method in which water paths are formed piercingly in the wall of a breakwater by varying the cross sectional areas of the water paths from the front opening to the back opening. CONSTITUTION:Waves which collide with the concrete wall face A of a breakwater form reflecting waves possessing the entire energy reflected immediately. Waves which collide with the reduced diameter path 2 easily go into the water path 1 but small amounts of waves are discharged from the back side B because the waves are consolidated due to the reduced diameter of the tip portion. Waves which collide with the increased diameter path 3 can not go into the water path 1 easily, but the water coming into the path 3 goes out from the back side B easily. Since the reflected waves possessing three kinds of different energies have many kinds of phase differences due to different generating times, they breakby cancelling each other and the energy of waves can thus be damped.

IPC: H04N9/78
Filed: 1984-07-31
Abstract: PURPOSE:To reduce effectively the deterioration of picture quality by providing a synthesization control means which changes each weighting of a synthesizing means according to the size of the detected horizontal and vertical components and controlling the specific gravity of correlation separation and the frequency separation of the 1st and 2nd Y/C separators in response to the results of detection of both horizontal and vertical components. CONSTITUTION:A synthesization control circuit 50 supplies a coefficient (k) to a synthesizing circuit 30. The coefficient (k) has the value accordant with the combination of an amount A showing the intensity of the vertical component supplied from a vertical component detecting circuit 40 and an amount B showing the intensity of the vertical component given from a vertical component detecting circuit 60. The coefficient (k) is reduced with increase of the amount A. In other words, the specific gravity of the signal occupied and coorelation separated in a synthetic signal is reduced as the intensity of the horizontal component is increased. This reduces the deterioration of picture quality due to the deterioration of correlation. While the (k) increase with increase of the amount B. In other words, the specific gravity of the signal occupied and frequency separated in the synthetic signal is reduced as the intensity of the vertical component is increased. This reduces the deterioration of picture quality owing to the cross colors or color ooze.

Title: Vibrating conveyor
Inventor: AKAMA MASARU
IPC: B65G27/20
Filed: 1978-12-29
Abstract: PURPOSE: To convey powdery and fragile materials safely, by turning two unbalanced weights for transmitting only horizontal vibration to a trough.  
     CONSTITUTION: A flat spring 34b is fixed to a carrier trough 1 through an angle 30, while its other end is fixed to a vibrating mechanism 6 through an angle 32. The vibrating mechanism has a pair of unbalanced weights 7, 8 set to rotary shafts 15, 16 in a bracket 10, and gears are arranged and driven by a motor M, so that the weights are turned at a certain ratio. Since only horizontal vibration is transmitted from the vibrating mechanism 6 through the flat spring 34b so as not to transmit vertical vibration to the trough, powdery matters never fly about nor fragile materials break off.

Abstract: PURPOSE:To count the number data of over all bits in a frame of even a high speed data by using a comparison circuit so as to compare simply the result of count of the (n-1)th frame and the n-th frame thereby obtaining the result of count for parity check. CONSTITUTION:A counter 100 counting the number of data of a reception data and a comparator circuit 102 detecting whether or not the count of the counter just before the reception of the said frame and the count of the counter just after the number of data of the said frame is counted, are provided and an output of the comparison circuit 102 is used as the counted result of the said frame. The counted result of the said frame is changed depending on the initial state frame when the counter 100 starts the count of the said frame. Since the initial state depends on the output of the counter 100 just before the reception of the said frame, the number of data of the said frame is known by comparing the said information with the output of the counter just after the count of the said frame is finished.

Title: Flip-flop association method between two logic circuits
Inventor: SAKAKI HIROMOTO
IPC: G06F17/50
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a method which can always secure the accurate FF association by performing this association via the comparison of functions if no association is secured by an FF association means. SOLUTION: The logic circuits 1 and 2 are inputted from the logic circuit files 120 and 121 respectively, and the labels F1 to F5 and G1 to G5 are attached to the FFs of circuits 1 and 2 respectively. In such cases, all FFs are not associated yet with each other. Thus, the FF association is first secured between both circuits 1 and 2 by an FF association means 1 based on the external signal/FF sharing rate. Then an FF association means 2 secures the FF association via the comparison of functions if no FF association is secured by the means 1. If no FF association is secured by the means 2, an FF association means 3 compulsively secures the FF association. Then the FFs which are associated with each other by the means 1 to 3 are outputted.
