Patent JP-S6486581-A (JP)
Title: Semiconductor laser and its manufacture
Inventor: HOSOI YOJI
IPC: H01S5/00
Filed: 1987-09-29
Abstract: PURPOSE:To obtain a semiconductor laser at a good yield which oscillates in a basic lateral mode and a single vertical mode, and has a low threshold level by a method wherein a mesa stripe is formed on a substrate for crystal growth, a current constriction structure and a ray confinement structure are formed by dispersion of impurities from the substrate. CONSTITUTION:N-type block layer 3, P-type clad layer 4 and N-type active layer 5 are formed, and the upper part of the mesa stripe 2 is formed as P-type region 6, then reverse bias state in this part is eliminated to make a current path in that part. On the other hand, in the region outside the mesa stripe, reverse bias is formed on the interface between the P-type clad layer 4 and the N-type block layer 3, accordingly no current passes there. That is, the current path is limited only on the mesa stripe 2 to provide a current constriction structure, and a low threshold can be prepared. Further when a P-type region is formed as in the above, refractive index of the P-type growth layer is greater than that of the N-type growth layer, consequently the structure for beam confinement is formed by the difference of the refractive indexes in the horizontal direction in the active layer to effect confinement of the beam. Accordingly oscillations in basic lateral mode and a single vertical mode are made possible.

Abstract: PURPOSE:To make the printing end times of all printing presses coincident with each other, by providing an arithmetic part calculating the designated number of printing for every printing press from the total number of printing and a drive part controlling a printing speed. CONSTITUTION:A controller is provided with a total printing number set part 4, a first printing press control part 1, a second printing press control part 2, and a third printing press control part 3. With the start of the operation of printing presses 5-7, the numbers of printing As, Bs, Cs which should be printed until the printing presses 5-7 start decelerating are calculated from the numbers of printing per unit time Ai, Bi, Ci outputted from the printing presses 5-7 and the total number of printing Pt, and the printing presses 5-7 are made to start decelerating when the total numbers of printing Ap, Bp, Cp which were printed by the printing presses 5-7 respectively became more than the numbers of printing As, Bs, Cs. Therefore, even with the dispersion in printing speed or with the difference in printing capacity among the printing presses, in all the printing presses the printing end times can be made coincident and the specified number of printing can be efficiently conducted within a specified time.

Title: Minimal/minimum value searching method
Inventor: MAKIMOTO NOBUO
IPC: G06F17/11
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To search only the minimal point of a function without waste by replacing the Hessian of a conventional Newton method with its absolute value. SOLUTION: A positive potential function 520p to rapidly take a large value near a set L of discovered zero points is multiplied a non-negative value function 510e desired to search the zero point. A resulting non-negative value function 530 g=g(θ; L) does not have the solution of gradient (g)=0 near L. When there is any value not included in the zero point of (e), on the other hand, it is the zero point of (g) and the solution of g=0. Therefore, by successively searching the solution of g=0, the plural different zero points of (e) can be searched.  Concerning the Newton method for finding the zero point of gradient (f) in order to search a minimal (minimum) point 550 of a minimal point search object function 530, the Hessian Hf is replaced with its absolute value Hf (as a symmetric matrix) so that only the minimal point (≠ saddle point and maximal point) can be efficiently searched.
