Title: Semiconductor light emitting device
Inventor: OGIWARA MITSUHIKO
IPC: H01S5/02
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a light-emitting-element structure which can be integrated at high density and whose production yield is high. SOLUTION: In a structure which is provided, a first clad layer 103, a first- conductivity-type active layer 104 and a second clad layer 105 are formed on a first multilayer reflection layer 102, and a second multilayer reflection layer 106 is formed on them. In a semiconductor substrate 100, the energy band gap of the multilayer reflection layers 102, 106 and that of the clad layers 103, 105 are larger than the energy band gap of the active layer 104. A second- conductivity diffusion region 110 is formed selectively on the semiconductor substrate 100. A second-conductivity electrode 102 which comes into contact with the second-conductivity diffusion region 110 is formed. A first-conductivity electrode 109 which comes into contact with a first-conductivity substrate 101 is formed on the rear side of the substrate 101.  As a result, a surface light emitting element of a planar structure which comprises a p-n junction to be used as a light emitting source can be formed inside the active layer 104. Since a mesa etching groove does not exist, a light emitting element can be integrated at high density, and a defect in a photolighographic process can be reduced.

Patent JP-S6348876-A (JP)
Title: Laser oscillator
Inventor: NAWA AKIYOSHI
IPC: H01S3/03
Filed: 1986-08-19
Abstract: PURPOSE:To decrease position deviation of an optical axis even if the temperature of a base is changed, to keep stable oscillating characteritics and to improve reliability, by using Ni cast iron as the material of the base, on which a plurality of discharge tubes and both reflecting mirrors are provided. CONSTITUTION:In the Table, thermal expansion coefficients of materials (a) constituting a base 1 are compared. Among the materials, the coefficient of Ni cast iron (b) has the smallest value. Above all, the thermal expansion coefficient of high Ni cast iron, which includes 30 wt % or more Ni, is about 1/3-1/4 those of gray cast iron (c) and steels for general structures. Therefore, the base 1 is formed with the high Ni cast iron having the small thermal expansion coefficient. In a laser oscillator constituted in this way, the position deviation of an optical axis becomes very small even if the temperature of the base 1 is changed due to radiant heat and the change in ambient temperature. A resonator can be maintained stably. Thus, deterioration in oscillating characteristics accompanying the temperature change of the base 1 is largely suppressed, and the highly reliable laser oscillator is obtained.

IPC: B41J11/58
Filed: 1983-10-20
Abstract: PURPOSE:To stabilize the frictional force necessary for the driving-out between paper sheets and a driving-out means by keeping the pressing pressure acting onto the driving-out means always nearly constant, independently of the number of pieces of paper sheets stored. CONSTITUTION:A pressing body 26 maintains inclined posture with respect to the upper surface of paper sheets by the urging of a spring, and one edge of the lower part is formed so as to be swung along the surface of the paper sheets, and a driving-out means 3 is formed in shiftable ways. A pressing-body posture detecting means 37 for detecting the swing posture of the pressing body, pressing-body driving means 42 for shifting the pressing body in the direction of accumulation of paper sheets, and an urging-force detecting means 23 for detecting the pressure applied onto the driving-out means from the displacement of the driving-out means are provided. Since the pressing-body driving means is controlled according to the signals supplied from a pressing-body posture detecting means and the urging-force detecting means, the friction force generated between the driving-out means and the paper sheets can be stabilized independently of the amount of the paper sheets piled into a receiving part.
