Title: Optical waveguide type optical element chip which has warpage deformation and is subjected to light phase adjustment
Inventor: NAGATA HIROTOSHI
IPC: G02F1/035
Filed: 1993-03-31
Abstract: PURPOSE:To enable the execution of the phase adjustment of exit signal light and the adjustment of a so-called operating point without using a DC electric field for control by delicately changing the refractive index of an optical waveguide by the strain generated in the waveguide. CONSTITUTION:The optical waveguide 2 is so formed in the prescribed part of a substrate 1 having a surface parallel with a direction X so as to have a thickness in a direction Z, This waveguide 2 is formed of a ferroelectric material having a photoelastic effect and is formed by diffusing, for example, titanium into Z-cut LiNbO3. A material different from the material forming the optical waveguide, for example, SiO2, is deposited on the substrate 1 having the optical waveguide 2, by which a deposited film layer 3 is formed. The internal stress is generated in this deposited film layer 3 and the laminate obtd. by this internal stress is warped and deformed to an arc shape. The strain parallel with the axial direction of the optical waveguide 2, i.e., the direction X, is generated in the optical waveguide by this warpage and deformation. The adjustment of the operating point of the optical element chip is executed by adjusting the strain quantity of the optical waveguide 2 to adjust the delay of the phase.

Title: Manufacture of semiconductor device
Inventor: KUNII YASUO
IPC: H01L21/3065
Filed: 1982-05-07
Abstract: PURPOSE:To enable the formation of an Si layer with excellent crystallinity by a method wherein the surface of a single crystal Si substrate is treated with HCl up to the temperature of the deposition of amorphous Si after being heat- treated by hydrogen and cleaned. CONSTITUTION:A spontaneous oxide film on the single crystal Si substrate is removed by heating the substrate to 1,100 deg.C or more in the atmosphere of high purity H2. Successively, the substrate is cooled down to 600 deg.C or less. At the temperature over 600 deg.C, it turns poly Si, and therefore amorphous Si of good quality is not depositioned. Thereat, utilizing etching effect by HCl, the surface is prevented from being re-contaminated by impurities in the atmosphere during cooling. An amorphous Si is vapor-grown on a clean Si surface and annealed, and thus the Si layer is formed by solid phase epitaxial growth. By this constitution, the single crystal Si layer of good crystallinity without the disorder of surface shapes can be obtained.

Title: Liquid fuel combustion device
Inventor: KAWAKAMI AKIO
IPC: F23D11/24
Filed: 1983-04-27
Abstract: PURPOSE:To restrict a carbon oxide or soot with the combustion flame from generating at the starting of the combustion by a method wherein secondary air is struck against the mixing gas flow of gasified fuel and the primary air passed in the flow regulator in such a way as it may be crossed at a right angle. CONSTITUTION:The secondary air is injected from the secondary air supplying holes 21 of the inner cylinder 14 over the flow regulator 20 in such a direction as crossing at a right angle with the axis of nozzles 17 and the flow regulator 20, and this air flow abuts (indicated by an arrow b) against the mixing flow of gasified fuel passed through the flow regulator 20 and the primary air. Since the eddy clow is produced at the abutted part of the gas and air, the combustion flame 24 is kept by this eddy flow. The mixing of the gasified fuel and the air is promoted by an agitating action caused by a supplying of the secondary air, resulting in producing a substantial complete combustion.
