Filed: 1994-02-08
Abstract: PURPOSE:To improve current constriction and, at the same time, to suppress the breakdown of the p-n junction of an active layer by the diffusion of a dopant contained in a current constricting layer so as to obtain a highly efficient semiconductor laser element having a low oscillation threshold current by forming a quantum well layer which suppresses the diffusion of the dopant to the active layer on the active layer side of the current constricting layer. CONSTITUTION:After forming a quantum well layer 13 which is composed of an i-type GaAs layer and a pair of Al0.4Ga0.6As layers and prevents the diffusion of a dopant by the MOCVD method, an n-type GaAs current constricting layer 8 is successively formed. As a result, the operating current can be reduced and the differentiating efficiency can be improved, because strains generated in the layer 13 store the dopant of the current constricting layer 8 and the diffusion of the dopant to the active layer 4 is prevented. In addition, a high yield can be obtained in the surface of a wafer.

Abstract: PURPOSE:To evaluate the degree of danger with a proper detection of an obstacle by a method wherein a detection area of the obstacle is divided into small areas having lapping parts and the lapping parts are altered according to running condition of a vehicle to judge the degree of danger of the obstacle detecting the obstacle at each small area. CONSTITUTION:A controller detects a steering angle and a vehicle speed with a steering angle sensor 5 and a vehicle speed sensor 6 to estimate a slippage angle of a body, a turning radius and the course of a vehicle. Then, a detection area is set within a scanning range of a light emitting device 2, namely, of a scan type laser and divided to rank the degree of danger. This detection area is determined by an angle of expansion from the center axis in the ongoing direction of the vehicle and has lapping parts in the adjacent small areas. The size of the lapping areas is changed according to operating condition. Then, the controller detects an obstacle to judge which small area the obstacle belongs to from the direction and distance thereof and a relative speed is calculated from changes in the distance. Then, the controller judges the degree of danger comprehensively in the light of the distance of the obstacle, behavior and the small area to which the obstacle belongs to decide how it controls.
