Title: Gate door opening and closing device for sluice
Inventor: MATSUI KATSUNORI
IPC: E02B7/26
Filed: 1982-08-24
Abstract: PURPOSE:To prevent the blocking of the water channel by counter-ballast by a method in which a pair of counter-ballasts are connected to the gate door through a wire rope in such a way that the counter-ballast can move vertically in the sliding grooves of weir pillars. CONSTITUTION:A sluice consists of a floor slab 1, paired weir pillars 2, retaining walls 4, and a gate door D vertically moving along the coupling grooves 2A of the weir pillars 2. The gate door opening and closing device consists of a pair of counter-ballasts 5, a pair of wire ropes 8 to connect the counter-ballasts 5 with the gate door D, and a drive mechanism for the wire ropes. The counter- ballasts 5 can vertically move in the sliding grooves 9 formed in the weir pillars 2. Since the inner face of the ballasts 5 are matched with the inner face of the retaining walls 4, no blocking occurs in the water channel when moving the ballasts 5 vertically.

Title: Self-diagnosing method
Inventor: NAKAO SADAO
IPC: G01R31/3185
Filed: 1981-09-17
Abstract: PURPOSE:To allow an exclusive arithmetic circuit which is used only for the execution of specific instructions to self-diagnose all the time, by inputting the counted value of a counter for diagnostic data generation as diagnostic data to the arithmetic circuit, and performing arithmetic and collation. CONSTITUTION:Before using an exclusive arithmetic device HSA, a central processing unit sets a control bit CB to 1 and when the CB is set to 0, the central processing unit enters into a diagnostic mode and a counter for diagnostic data goes by one successively to perform counting from an all-0 value to an  all-1 value. While the CB is 0, a multiplexer MPX is switched to input the data  of the CTR to arithmetic units ALU1 and ALU2, so three-divided data A, B,  and DF of the counter CTR are inputted to the ALU1 and ALU2 together. A comparator COMP compares them mutually and when they do not coincide with each other, an error signal ER is generated. The capacity of the counter  CTR is equal to data width and it adds by one successively, so a diagnosis is  performed by combinations of all input patterns.

Abstract: PURPOSE: To continue stable feed-water operation, by precedently adding a stabilized compensation signal in response to the change of a system head.  
     CONSTITUTION: A system head is detected by means of a detector 6, the detected output is given to a primary delay element 8 of a compensation circuit 7, deviation between the delay output and the detected output of the system head detector 6 is computed by means of an adder 9 and the computed results are input to said adder 1 as a leading compensation control signal COM. Consequently, the compensation control signal COM functions as incomplete differentiation, and becomes large in response to the sudden change of the system head even if there happens the sudden change, thus precedently working the signal to a feed-water controller 2, then beforehand avoiding the effects of the disturbance that must be formed to the response of flow rate discharged. As a result, stable feed-water operation can be continued.

Abstract: PURPOSE:To automatically correct correcting value for weighing, by setting the next correction value for difference by adding or subtracting a value obtained by multiplying a correction factor of 0-10% to the difference between the weighed value and set value to or from the last correction value for difference. CONSTITUTION:The next correction value for difference is set by adding or subtracting a value obtained by multiplying a correction factor of 0-10% fixed for each weighing brand to the difference between the last weighed value and the set value to or from the last correction value for difference, and it is arranged that, when the diffeence between the weighed value and the set value exceeds a prescribed value, no corecting operation is made and only an alarm is generated. For example, after a rough weighing is completed in a 2-step weighing controlling system, preset DELTAWN(=set value for minute weighing - last correctin value for difference) is comparted with the minute weighed value, and, when the difference is within an allowable range, the next correction value is set by adding or subtracting a value obtained by multiplying a pescribed correction factor to the difference, and then, the next correction value is stored. When the difference exceeds the allowable range, an alarm is generated and the processing is performed through manual operations.
