Title: Crystal growth method of ii-v compound semiconductor
Inventor: FURUHATA NAOKI
IPC: H01L21/205
Filed: 1986-10-08
Abstract: PURPOSE:To eliminate the distortion of lattice while attaining the higher carrier concentration by a method wherein, when III-V compound semiconductor is doped with donor impurities, said semiconductor is simultaneously doped with impurities with larger or smaller atomic radii than that of host element. CONSTITUTION:Material gas and doping gas led in a reaction tube 2 from a gas inlet 1 are decomposed on a substrate 3 mounted on a carbon-made pedestal 4 heated by high-frequency coils 5 to produce a compound semiconductor. Within the reaction tube 2, GaAs is doped with Si, Sn using trimethylgallium (TMG), arsine (AsH3) as material gas as well as silane (SiH4) containing Si, tetramethyl tin (TMSn) containing Sn as doping gas. Si and Sn are impurities substituting for Ga to be donors subject to the atomic radii of Si<Ga<Sn i.e. respectively represented by 1.17A, 1.26A, 1.40A of the atomic radii. Through these procedures, when the substrate 3 is doped with impurities with larger or smaller atomic radii than that of III group element, lattice can be relieved to eliminate any distortion thereof.

Title: Method for measuring optical characteristics of soft contact lens and measuring container used therefor
Inventor: IKEZAWA YUKIO
IPC: G01M11/02
Filed: 1997-09-05
Abstract: PROBLEM TO BE SOLVED: To suppress natural drying and deformation due to empty weight of a contact lens by measuring the optical characteristics of a soft contact lens being placed on a lens pad in the air while dipping a circumferential part into liquid for preventing drying. SOLUTION: A lens pad 19 of a measuring container 6 is a conical trapezoid- shaped cylinder body, and a placement part 19a for placing a soft contact lens 9 is provided at the upper part of the lens pad. Also, a liquid storage part 21 is provided around the lens pad 19 and stores a preservation liquid 25 for preventing the contact lens 9 from being dried.

Title: Three-dimensional image pickup method and device
Inventor: TOKAI KEN
IPC: G01B11/00
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To precisely perform the range finding of a wide range with a simple light source by projecting a projecting light changing with time to a subject to be measured, and decoding the reflected light from the subject to be measured according to the time change of the projecting light. SOLUTION: A projecting light 2 changing with time projected from a stroboscopic light source 1 is diffusively reflected by the surface of a subject 9 to be measured, and a reflected light 3 reaches a light receiving optical system 41. The reflected light 3 passes an intensity modulator 42 arranged on the imaging surface of the light receiving optical system 41 and reaches a light receiver 43. The intensity modulator 42 decodes the reflected light 3 with an intensity modulation based on the signal from a phase shifter 6. Namely, the reflected light 3 is decoded according to the time change of the projecting light 2. The decoded light is received by the light receiver 43, converted into an electric signal and accumulated for a fixed time.  The distance information and luminance information are calculated from the decoded and accumulated signals by an unknown variable calculating processor 7 and stored in a three- dimensional image memory 8.
