Title: Division system and its device
Inventor: OKAMOTO FUYUKI
IPC: G06F7/535
Filed: 1988-06-23
Abstract: PURPOSE:To realize the high-speed processing with a division device by performing the repetitive multiplication for convergence of the divisor side and the repetitive multiplication for convergence of the dividend side in parallel with each other via two multipliers. CONSTITUTION:The convergence factors obtained recurrently are repetitively multiplied by a divisor and a dividend respectively. Then the repetitive multiplication result is converged to 1 at the divisor side together with the repetitive multiplication result converted to the quotient at the dividend side respectively. In such a convergence type division, the repetitive multiplications for convergence of the divisor and dividend sides are carried out in parallel with each other via two multipliers.In other words, two multipliers 140 and 141 of m-bit Xm/2-bit are used to carry out the repetitive multiplications in parallel to each other for convergence at the denominator (divisor) and numerator (dividend) sides respectively (m: valid digit number of the data on divisor, dividend, quotient, etc.). In such a way of the parallel calculations carried out via both multipliers 140 and 141, the processing time can be shortened in a division system.

Abstract: PROBLEM TO BE SOLVED: To prevent the effect of detection delay of a fuel pressure sensor while improving atomization of injection fuel by high fuel pressure. SOLUTION: This control device is provided with a variable high-pressure regulator 32 for regulating fuel pressure on the discharge side of a high-pressure pump 32 to be driven by an engine to optional set pressure or less. Supplied fuel is received from a fuel passage between the variable high-pressure regulator 32 and the high-pressure pump 31, and a fuel injection vale 33 injects and supplies the fuel amount corresponding to the driving time to the engine. A calculating means 34 calculates target fuel pressure PTG on the discharge side of the high-pressure pump 31 on the basis of a predetermined fuel pressure increasing speed basic value, and a control means 35 controls set pressure of the variable high-pressure regulator 32 so that fuel pressure on the discharge side of the high-pressure pump 31 may become the target fuel pressure PTG.  A calculating means 36 calculates the driving time TPULS of the fuel injection valve 33 according to the target fuel pressure PTG, and a driving means 37 drives the fuel injection valve 33 by using the driving time TPULS.

Title: Submarine topography reproducer
Inventor: SHIBUYA SHOZO
IPC: G01S15/89
Filed: 1984-07-26
Abstract: PURPOSE:To reproduce a 3-D configuration of the sea bottom, by determining position data for the depth of the sea bottom and cutting identifying sea bottom signals within wave means received to form the configuration of the sea bottom into pattern paper pieces by cutting based on individual position data while the pattern paper pieces are laminated in the sequence of time. CONSTITUTION:As the depth of the sea bottom and position data are determined with a transmitter/receiver and a computer, cutting starts with a laser light generator 28. The cutting is repeated starting from the (m1)th in sequence of m1+1, m1+ 2... and stops immediately shifting to (m2)th. Then, the subsequent transmitting and receiving operation is performed. After the formation of the pattern paper pieces 30, cut pieces left are removed by a paper removal signal, for example, with a sucker or the like (not illustrated). A rotary arm 31 turns right from the bottom to the top by 180 deg. to load an overlap drum 32 with the pattern paper pieces 30. A fastener 33 holds the pattern paper pieces 30 overlapped. As the rotary arm 32 returns down to the original position, upon the end of loading with paper pieces, a motor 25 rotates by a signal to set the original 23 at the specified position through a roller 27. In this manner, one pattern paper piece for the sea bottom displocation is formed each time transmission or reception is done while the pattern pieces are laminated in the sequence of time thereby enabling the reproduction of the configuration of the sea bottom in a wide range.

Abstract: PURPOSE:To achieve stabilization of paper delivery from which shear in printing among several sheets superimposed duplicate paper layers is removed by a method wherein a height of a separator which guides paper discharged from a paper delivery opening is so constructed as to vary in several stages or continuously. CONSTITUTION:Paper P is wound around a platen 12 by a specific angle, and printing is performed with a printing head 13. When paper P is discharged from a paper delivery opening 17 by rotating a platen 12 thereafter, a height of a separator 16 which guides the delivered paper P is so constructed as to vary in several stages or continuously. For instance, in the case where the height of the separator is manually varied in no stage, a rack 20 is formed to a support lever 19 attached almost vertically the separator 16. A driving gear 22 and a pinion 21 are rotated by operating manually a manual driving knob 23 to make the support lever 19 slide vertically. Further, in the case where, for instance, the height of the separator is electrically varied in no stage, when paper selective buttons 29a-29c are selectively pushed down, a motor control circuit 27 rotates a stepping motor 28, and the separator 16 is located at a height corresponding to the selected paper.

Pressure air is delivered backward and the sludge removal by back washing is executed when the amt. of the sludge sticking to the outside wall of the filter attains a prescribed value in the filtration process. This stripped sludge is discharged together with the remaining fluid into a back washing junction tank 17 and is made into the thick sludge liquid. The thick liquid is force-fed to the dehydration filter machine 3 and is filtered. The high-pressure air is blown to dehydrate the sludge when the amt. of the sludge sticking to the inside wall of the filter attains the prescribed value. The dehydrated sludge is stripped by rotation of a blade, etc., and is discharged. The filtration of the waste fluid and the dehydration of the sludge are thus efficiently executed.
