Title: Position control method
Inventor: FUTAMI SHIGERU
IPC: G05B19/23
Filed: 1988-10-21
Abstract: PURPOSE:To perform position control with fast response and high accuracy by feeding a position and a speed back negatively and feeding acceleration back through a primary delay circuit and the speed back through an approximate differentiating circuit positively. CONSTITUTION:In addition to the negative feedback of the position and speed, the acceleration (a) is measured by an acceleration sensor and passed through the primary delay circuit to constitute a positive feedback loop, or the speed (v) is measured and passed through the approximate differentiating circuit to constitute a positive negative feedback loop. Here, the primary delay circuit and approximate differentiating circuit are easily constituted by using operational amplifiers. Thus, vibrations by the positive feedback of the acceleration (a) are stabilized to increase the gain of a speed and position control system, so a position control system which has fast response and high accuracy can be constituted.

Title: Laminated or coated regenerated cellulose film and its manufacture
Inventor: KUBOTA SHIZUO
IPC: C08L101/16
Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent a solid residue from being generated when a regenerated cellulose film is discarded as refuse and buried in the soil by laminating or coating a biodegradable resin on a regenerated cellulose film through an anchoring agent consisting of a hydrophilic polymer compound. SOLUTION: First, an anchoring agent consisting of a synthetic polymer compound such as a polyvinyl alcohol resin dissolved in a hydrophilic solvent such as methanol is applied to the surface of cellophane and the coat is dried. Further, a resin liquid or an aqueous dispersion consisting of a biodegradable resin with biodegradability such as a polymer of hydrocarboxylic acid dissolved is applied and dried to obtained a coated film. The coated film thus obtained has biodegradability in not only a regenerated cellulose film but also in the biodegradable resin applied. In addition, the anchoring agent is also degradable in the soil and is soluble in water so that no residue is generated. Thus it is possible to bury this regenerated cellulose film in the soil as a method for disposing of refuse.

Filed: 1988-10-24
Abstract: PURPOSE:To prevent the nonuniform heating of a material to be heated during the stoppage of conveyance by stopping the lead of the unextracted group of materials on the heating zone side except the nose part, and continuing the extraction of the extracted group of materials on the soaking zone side at the time of stopping the continuous conveyance in the heating furnace due to the factors of the succeeding stages. CONSTITUTION:A slab 8 is continuously charged into the heating furnace, conveyed successively through a preheating zone, first and second heating zones 2 and 3, and the soaking zone 4 by moving beams 5, 6, and 7, and discharged. When the continuous operation is stopped due to the factors of the succeeding stages (exchange of rolls, etc.), the expected stopping time is inputted to a computer, and the moving beams 5 and 6 are stopped so that the slab 8A to be stopped at the lead on the moving beam 6 is stopped directly before the nose part 10. Only the moving beam 7 is still moved to extract the remaining extracted slab 8B, and then stopped when the slab 8B is extracted. As a result, the temp. lowering of the slab 8 at the nose part 10 during stoppage is prevented, and nonuniform heating is obviated.

Title: Paper roll cutting device
Inventor: HIRATSUKA YOSHINORI
IPC: B65H35/02
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To reduce resources and raw material costs by decreasing the amount of trimming of a paper roll. SOLUTION: In a paper roll cutting device, the trimming width of the end of a paper roll R is restrained to the minimum extent when the wide paper roll is cut into the paper roll having the desired width by a cutter. Many holding needles 5a are erected on a holding plate 5 facing the end surface R1 of the paper roll and to be advanced and retreated, the end surface is pricked with the holding needles, and the end surface of the soft paper roll can be held. When a cutter 13 cuts the paper roll from the outer peripheral part, the cut end is not deformed even if pressing force of the cutter acts on it, and the paper roll can be cut perpendicularly and flat in the longitudinal direction of the paper roll. Since the width of trimming can be decreased to such an extent that the cutter is not brought in contact with the holding needles, a part to be wasted can be decreased.

Title: Partial differential equation processing system
Inventor: IOGI NOBUHIRO
IPC: G06F17/13
Filed: 1990-10-08
Abstract: PURPOSE:To improve the calculation efficiency of this processing system by constituting a rigidity matrix in such a way that detection of lines having the same-value non-zero sections is performed on each line in the rigidity matrix and, when such lines are detected, calculation of a discrete equation is not performed, but an already calculated line having a non-zero component of the same value is used for substituting one of the lines. CONSTITUTION:When a pattern table is prepared against each grid point in a small area by patterning the relative positional relations of the grid points referred by a partial differential equation, detection of lines having same-value non-zero sections can be performed on each line in a rigidity matrix. Accordingly, the lines having the same-value non-zero sections can be processed by performing the calculation of a discrete equation on one grid point and substituting the calculated result for the other line. Therefore, the calculation efficiency can be improved by reducing the number of calculation at the time of producing the rigidity matrix.
