Title: Material for spring
Inventor: AYADA TOMOHIKO
IPC: F16F1/02
Filed: 1988-05-13
Abstract: PURPOSE:To obtain the material for springs which is relieved in notch sensitiveness, is improved in fatigue resistance and has good workability by tempering the material to the hardness distribution in which the peak of hardness is formed on the surface layer part and the hardnesses on the surface and central surface are smaller than the above-mentioned peak value. CONSTITUTION:This material for springs is so tempered as to have the hardness distribution in which there is the peak of the hardness on the surface layer part and the hardnesses on the surface and the side nearer the center than the surface layer part are both smaller than the above-mentioned peak value. Said material has the excellent fatigue resistance and ductility and can be easily formed to springs, etc. The above-mentioned hardness distribution is preferably set at l1>=2l2 when the distance from the surface to the point where the hardness begins to change is designated as l1 and the distance to the peak position of the hardness as l2. Further, such a hardness distribution that the peak position of the hardness is between the peak position of the residual compressive stress imparted by shot peening and the position to generate the max. stress at the time of using the spring is more preferable.

Title: Preparation of light-emitting diode
Inventor: KANEKO TOSHIAKI
IPC: H01L33/40
Filed: 1979-09-11
Abstract: PURPOSE:To improve the external quantum efficiency of a light-emitting diode by diffusing p type impurities into a semiconductor substrate of a III-V group compound containing Ga by using an insulative film mask having an opening, before selectively removing the film on the opening circumference and providing an electrode on the shallow projecting diffused region produced on the circumference. CONSTITUTION:An n type GaAlAs substrate 1 is coated with an SiO2 film 3, in which an opening 2 is made. Zn is diffused in the opening 2 to produce a p type region 4 in order to form a pn junction 8. On doing this, since the film 3 allows not As, P and the like but Ga to pass through, the Ga in the substrate 1 slips out and is replaced by Zn, which is activated to form a shallow p type region 4'' projecting on the circumference of a desired region 4'. Therefore, this is positively used. The film 3 on the region 4'' is removed by etching with a portion of the film 3 left on the region 4'', and an electrode 6 of Cr-Au-Zn is provided on this covering the film 3. An Al2O3 film 9 produced on the region 4' is let as it is, because it is thin. Thus, the electrode 6, which usually extends into the region 4', is made to retreat  to make the light-emitting surface and the light lead surface the same size.

Abstract: PURPOSE: To increase the light output from the light-take-out surface, by providing fine and irregular indentations on the light-take-out surface of an N-type Ga 1-x  Al x As layer and thereby reducing the total reflection taking place at the boundary of air and the light-take-up surface.  
     CONSTITUTION: In this photodiode, N-type Ga 1-x Al x As layer 3, N-type Ga 1-y  Al y As layer 11 and P-type GaAs layer 6 are formed by epitaxial growth on N-type GaAs base 2, a window reaching N-type Ga 1-x Al x As layer 3 is provided on a part of N-type CaAs base 2, and the surface on N-type Ga 1-x Al x As layer 3 is made rough. The junction between P-type region 13 diffused from P-type CaAs layer 6 and N-type Ga 1-x Al x As layer 3 forms light-emission region 9. Since N-type Ga 1-y  Al y As layer 11 has a larger band gap than N-type Ga 1-x Al x As layer 12, current does not flow in the junction with P-type region 13 but concentrates and flows in the junction between P-type region 13 and the Ga 1-x Al x As layer.
