IPC: H01S5/00
Filed: 1983-02-07
Abstract: PURPOSE:To oscillate a semiconductor laser in low threshold value and high efficiency by forming two ridges having P-N junction parallel to the main surface of a substrate on the surface of the substrate and forming layers including active layers thereon. CONSTITUTION:The P type first current narrowing layer 9, the N type second current narrowing layer 10 and the P type third current narrowing layer 11 are epitaxially grown on an N type substrate 1. Two parallel ridges are formed by etching on the wafer. The first layer, N type clad layer 2, the second non-doped active layer 3, the third P type clad layer 4 and the fourth N type current limiting layer 5 are further grown on the substrate 1. Then, P type impurity is selectively diffused in stripe shape on a groove between the ridges from the grown surface. Since the ridge becomes reverse bias of the P-N junction, the current implanted from the diffused region to the layer 4 is not flowed to the ridge, but concentrated to the active layers which oscillate.

Title: Production of magnetic powder for sr-ferrite magnet
Inventor: TSUGAI NORIJI
IPC: C01G49/00
Filed: 1992-02-04
Abstract: PURPOSE:To lower super-fine powder content to the utmost so as to prevent the formation of coarse crystal grain due to burning by adding B2O3, etc., after calcination of magnetic powder. CONSTITUTION:Sr-ferrite calcined substance in which Fe2O3/SiO is 5.5-6.1 in mole ratio is coarsely crushed into grains with a mean grain diameter of 2-3.5mum. The obtained coarse powder is added with at least one of B2O3, Bi2O3, and In2O3 by 0.2-0.5wt.%, and is applied with heat treatment at 1000-1150 deg.C for 0.5hr or longer, then it is finely crushed. Through addition of the calcined coarse powder and heat treatment, super-fine powder disappears and the grain distribution becomes uniform. Further, irregular grain surface as well as crystal strain inside the magnetic powder as driving force for coarse grain growth, which are generated by crushing the Sr-ferrite calcined substance, are removed by performing such a heat treatment. When mean grain diameter of the calcined coarse powder exceeds 3.5mum, super-fine powder will be generated during fine- crushing of post-process, resulting in forming coarse crystal grain when a ferrite magnet is subject to burning.

Title: Apparatus for inspecting printed board
Inventor: TAKAHASHI KAZUYA
IPC: H05K3/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To simply exchange springs and press rods, and protect parts such as wires or the like from being hooked by springs. SOLUTION: In an inspecting apparatus 30 for printed boards, a top plate 37 is fixed at the side of a face of a supporting plate 36 opposite to a printed board 2. Springs 22 are set at a lower face of the top plate 37 so as to urge upper ends of press rods 35. In order to inspect the printed board 2, the printed board 2 is loaded at a predetermined position of the apparatus and a board- pressing part 34 is lowered. At this time, the press rods 35 are urged to the printed board 2 by the springs 22. Even when a leading end of the press rod 35 butts against an electric, electronic part (element) on the printed board 2, the spring 22 is shrunken in accordance with the fall of the board-pressing part 34 and therefore elements and printed board 2 are not damaged.  Since the springs 22 are arranged at the side of the upper face of the supporting plate 36 which is opposite to the printed board 2, a lead wire or the like component disposed on the printed board 2 is prevented from being hooked, and moreover, the springs 22 and press rods 35 can be exchanged simply by detaching the top plate 37.

Abstract: PURPOSE: To prevent the mixing of mists into condensed water, and to obtain the condensed water with high purity, by a mechanism wherein steam flow paths and the collecting passages of the mists are formed by means of a condensed liquid tray and a guide plate additionally mounted to the tray.  
     CONSTITUTION: Seawater fed from a water supply port 12 for heating is heated by a heating medium fluidized in heating tubes 2, and flashed and vaporized. The surface of a brine liquid oscillates when the seawater is flashed and vaporized, and steam currents are accompanied by liquid-drops and mists. Steam accompanied by the liquid-drops and the mists is divided into two directions against a condensed liquid tray 4 and rises in the pan, and collides near an inlet of a void portion 7, and the grain diameters of the mists that the steam currents are accompanied are enlarged. The steam currents joining near the inlet of the void portion 7 are admitted into the tray 4 by sucking force in the tray 4. The mists collide with a guide plate 6 by centrifugal force at that time and adhere to the plate and are collected, flow down along an inwall, and are discharged outside the pan through a drain extracting pipe 9. Steam whose mists are separated at the void portion 7 condenses in the tray 4, and is extracted from a condensed water extracting port as generated distilled water.
