Title: Controller for link having low rigidity
Inventor: KURAKAKE MITSUO
IPC: G05B13/02
Filed: 1986-09-16
Abstract: PURPOSE:To effectively perform damping, by converting deviation between the speed of a servo motor, and that of the load of a link with low rigidity coupled to the motor through a spring factor, to acceleration deviation, and changing the feedback gain of the difference of the speed corresponding to the acceleration deviation. CONSTITUTION:The speed X1(s) of the motor, and the speed X3(s) of a mechanical load for a position command signal u(s) can be found by equations I and II, assuming the inertia of the motor and the mechanical load as Jm, and JL, coupling spring factors of them as K, the feedback gain as k1, and a differentiation term as S. Therefore, a speed deviation signal (a) can be obtained from (X1-X3), and furthermore, an acceleration component signal (b) can be obtained by performing the multiplication of the differentiation item S. Meanwhile, the acceleration command signal (c) of the motor is (1/Jm)Xu(s), and the acceleration deviation (d) is a difference between the signals (c) and (b). By selecting the k as 0<k1<1, and setting as an absolute value ¦(1/Jm)Xu(s)-S{X1(s)-X3(s)}¦>= an absulute value ¦(1/Jm)Xu(s)¦, the damping of a control system can be effectively suppressed even when the inertia JL of the mechanical load is varied.

Title: Method and device for correcting ruled line of table
Inventor: IEDA JIRO
IPC: G06F19/00
Filed: 1994-09-12
Abstract: PURPOSE: To simply correct a table constituted of vector ruled lines. CONSTITUTION: An X-coordinate extracting part 1 extracts one or plural X- coordinates from vertical ruled lines in ruled line information recognized from an image. An inter-X-coordinate distance calculating part 2 calculates a distance between plural X coordinates extracted by the extracting part 1. When the distance between the X-coordinate calculated by the calculating part 2 is included within a correcting distance range, an X-coordinate determining part 3 determines one X-coordinate and then determines the X-coordinate of all vertical ruled lines. An end point extracting part 4 extracts the end point of a horizontal ruled line. A distance comparing part 5 calculates a distance between the X- coordinate determined by the determining part 3 and the end point extracted by the extracting part 4.  When the distance calculated by the comparing part 5 is included within the corrected distance range, an X-coordinate correcting part 6 corrects the X-coordinates of the horizontal ruled line. Since vertical ruled lines also are similarly corrected, fine ruled lines can be obtained.

IPC: F16H41/28
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To eliminate remaining tensile stress in the bending part on an outer peripheral corner and to improve the durability of a flat plate by pressing a pressing member against the inside of a corner bending part of the flat plate at a prescribed load. SOLUTION: A lockup piston 21 is set on a jig, load P is added to a roller 81 by a pressing means in the direction of the arrow C and the outer peripheral edge part 85 is pressed against the inside of the bending part 69 on the outer periperal corner. By a shifting means arranged on the roller 81, the outer peripheral edge part 85 is shifted along the surface of the inside of the bending part 69 on the outer peripheral corner in the direction of the arrow D. At this time, the inclination of the center axis 82 of rotation is made constant and an approximate right angle to the direction of the arrow C is made. Consequently, because plastic working is executed in the vicinity of the center (a) of bending on the inside of the outer peripheral bending part 69, it is possible to reduce or remove the tensile stress remaining in the vicinity of the center (a) of bending.  Moreover, by increasing the load P, it also is possible to make compressive stress remain in the vicinity of the center (a) of bending.

Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To suppress temperature fluctuations in the wavelength of laser oscillation by employing a mixed crystal of GaInNAs in an active layer and a III-IV compound semiconductor in a clad layer. SOLUTION: At least a part of an active layer 103 is made a mixed crystal of GaxIn1-xNyAs1-y contains nitrogen, as well as clad layers 102, 104 is made a III-V semiconductor containing nitrogen. Preferably, the clad layers 102, 104 comprise Al1-x-yGaxInyNzAs1-z, Al1-x-yGaxInyNzP1-z or GaxIn1-xNyAszP1-x-y. Since the clad layers 102, 104 comprise a III-IV semiconductor containing nitrogen and lattice matching can be taken with a GaAs substrate, crystal quality deteriorating due to lattice matching is not caused. Furthermore, the temperature dependence of the oscillation wavelength of laser is reduced, because temperature dependence of the band gap and refractive index is low in the active layer 103 and the clad layers 102, 104.
