Title: Production of glass
Inventor: TAKEUCHI TETSUHIKO
IPC: C03B19/12
Filed: 1986-10-27
Abstract: PURPOSE:To produce a large-sized glass with high quality by allowing a gelling temp. of the sol to be a specified low temp. and keeping the temp. until the shrinkage of the wet gel begins to start in the production of glass by the sol-gel method. CONSTITUTION:A liquid sol consisting of the component of the aimed glass is prepared from alkyl silicate and hyper-fine powdery silica as main raw materials and then the glass is produced by the sol-gel method wherein the gel is dried and sintered after gelatinization of the sol. Now the prepared sol is gelatinized at the temp. of <=5 deg.C and the obtained gel is allowed to stand still while slowly returning from the above-mentioned gelatinized temp. to the room temp. at the point when the shrinkage of the wet gel begins to start. In this way, because the sol is gelatinized in low temp., the reaction speed of the dehydration polycondensation is slowed, so the nonuniformity of the reaction in the sol is eliminated. Therefore, large-sized glass of high quality is obtained without any defect in the strength distribution and the bonding of the gel.

Title: Semiconductor laser device
Inventor: TANAKA TOSHIO
IPC: H01S5/00
Filed: 1987-10-09
Abstract: PURPOSE:To improve the reliability and service life of a semiconductor laser device by forming a dislocation getter layer having a large crystal defect density on the part of a crystal layer grown partly on or on a semiconductor substrate, and forming an active region on a section isolated from the getter layer. CONSTITUTION:A dislocation getter layer 8 having a large crystal defect density is formed on the part of an epitaxially grown crystal layer, i.e., on the part between P-type AlGaAs clad layers 2 on a P-type GaAs substrate 1. A region having many dislocations is intentionally formed on the part of the epitaxial layer, and an active region 10 for generating a laser oscillation is formed on the part of a P-type GaAs active layer 3 isolated from the layer 8. The dislocation generally very improves crystallinity near the dislocation by its gettering effect. Since the dislocation in a crystal is concentrated only in the layer 8, the crystallinity in the region 10 can be effectively improved. As a result, the reliability and the service life of a semiconductor laser device can be sufficiently enhanced.

Abstract: PROBLEM TO BE SOLVED: To make the whole optical system small in size and simplified and to obtain a focusing error signal, photometric signal or the like by disposing a beam separating means to separate the incident light into a plurality of beams near the entrance face or exit face of an optical element. SOLUTION: The light 6 from an object OB is controlled for the quantity of the incident light by a diaphragm 4 and then enters a concave refraction plane R1 of an optical element 1. The light entering the concave refraction plane R1 is changed into divergent light of the objective light 6 by the power of the concave refraction plane R1 and is reflected by a concave mirror 2 to form a primary image of the object on an intermediate imaging plane N1 by the power of the concave mirror 2. The incident light 6 is separated by a diffraction grating 10 into zero-order light and first-order diffracted light.  The first- order diffracted light as a separated beam 13 separated from the main beam along the referential axis 5 enters the concave refraction plane R1, propagates in the direction to a transmitting plane T1 without reflected by reflection planes R2, R3, and exits from the transmitting plane T1 to the outside of the optical element 1. The separated beam 13 exiting from the device passes a condenser lens 11 and enters a photodetector 12, which detects the quantity of the light.
