Abstract: PURPOSE:To reduce an operation current and to simply form electrodes by narrowing an interval between impurity diffused regions at an active layer position to be diffused with the impurity near an active layer as compared with the width of a clad layer of an electrode forming side. CONSTITUTION:A p-type impurity of Zn, Be or the like is implanted by an ion implanting method to a surface including a MQW active layer 1 of a region etched at both sides for holding a stripe, thereby forming an ion implanted region 60. Then, a mask 50 is removed, the implanted impurity is diffused and moved by heat treating so that the interval between the diffused parts becomes 2mum or less at the layer 1. In this case, the thickness of an n-type AlGaAs clad layer 2 is sufficiently increased to eliminate the influence of the diffused part to an n-type GaAs contact layer 20, and a p-type electrode 100 and an n-type electrode 101 are eventually formed. Thus, the threshold value of an operation current can be reduced, and a laser having a stable oscillation mode is obtained.

Title: Checking method for wheel alignment and apparatus thereof
Inventor: FUKUBAYASHI SHINJI
IPC: G01M17/00
Filed: 1979-01-25
Abstract: PURPOSE: To conduct measurement of a caster and a camber angle in a simplified manner at an  improved accuracy, by using ameasuring jig which is provided with two inclinometers and which  is set on the axis of a king pin, whereby the inclination of the king pin in the direction of the  length of the vehicle and the inclination of the king pin in the direction of the width of the vehicle  are measured.  
     CONSTITUTION: A vehicle is placed on an alignment regulation mechanism. A link 25 is operated  to set clamp members 11, 12 of a jig 10, which is provided with two inclinometers, between studs  20, 21 provided on the axis of a king pin, and an inclination α of the axis K of the king pin in the  direction of the length of the vehicle and an inclination γ of the axis K in the direction of the  width of the vehicle are measured. The inclination α in the direction of the length of the vehicle  indicates a caster as it is. A camber angle β is then determined by subtracting the inclination γ of  the axis K in the direction of the width of the vehicle from a constant angle L between the perpendicular center line Sv, which is at right angles to the axis S of a spindle, and the axis K of the  king pin. A caster and a camber angle can thus be measured simultaneously with one measuring  jig. In other words, a caster and a camber angle can be measured in a simplified manner at a  high accuracy.
