Patent JP-H02228027-A (JP)
Title: Manufacture of compound semiconductor substrate
Inventor: FUJITA KAZUHISA
IPC: H01L21/205
Filed: 1989-02-28
Abstract: PURPOSE:To alleviate thermal stress strain and to prevent the deterioration in the crystal property of a semiconductor and the occurrence of the warping of a wafer by epitaxially growing a compound semiconductor selectively on an Si substrate through a metal mask. CONSTITUTION:A metal mask 2 made of Mo for selectively growing a compound semiconductor layer 3 comprising GaAs is provided on an Si substrate 1. When the GaAs layer 3 is grown, the temperature in a furnace is increased up to 750 deg.C in an AsH3 atmosphere. Then, TMC is introduced into the furnace. A GaAs layer 3b is epitaxially grown on a GaAs layer 3a to a thickness of several mum by high temperature growing. Thus the GaAs layer 3 is formed. thereafter, the temperature in the furnace is returned to room temperature, and the Si substrate 1 on which the GaAs layer 3 is grown is taken out of the furnace. When the GaAs grows, the GaAs grows only at the opening part of the metal mask. Therefore, thermal stress strain caused by the difference in thermal expansion coefficients can be alleviated when the temperature is decreased from the growing temperature to the room temperature. thereby, the deterioration in crystal property of the GaAs and the occurrence of the warping of the wafer can be prevented.

Abstract: PROBLEM TO BE SOLVED: To maintain a strong magnetic force and enable easy magnetization, by integrally coupling a plurality of narrow-width rubber magnetic material units having NS magnetic poles directed toward the direction of width of a bandshaped flexible magnetic material with a predetermined width, into the direction of width with respect to the direction of the magnetic poles as the forward direction, thus constituting a magnetic band-shaped material. SOLUTION: A band-shaped flexible magnetic material 1 is formed by coupling a plurality of narrow-width rubber magnetic material units 1a having NS magnetic poles directed toward the direction of width of the band-shaped flexible magnetic material, into the direction of width with respect to the direction of the magnetic poles as the forward direction. Thus, a magnetic band-shaped material having a predetermined width W is constituted. The rubber magnetic material unit 1a is constituted by a composition containing rare-earth based magnetic powder at 30-68 wt.% and a binder at 32-70 wt.%. The rubber magnetic material unit 1a has a rectangular cross section with a thickness of 3-12 mm and a width of 7-15 mm.  Thus, since the spacing between magnetization balls 2 and 2 for magnetizing the narrow-width rubber magnetic material unit 1a can be narrowed to not more than 20 mm, sufficiently strong magnetization can be carried out without increasing a magnetization power source.

Title: Optical fiber
Inventor: KUBO YUJI
IPC: G02B6/036
Filed: 1988-03-04
Abstract: PURPOSE:To obtain a 1.3mum-zero dispersion single mode optical fiber which has a small light transmission loss and is superior in resistance to circumstances and has a high reliability by providing a structure consisting of a center core, whose center part at least consists of pure quartz, and a peripheral core. CONSTITUTION:For the purpose of realizing the zero dispersion wavelength approximating 1.3mum, the difference of specific refractive index between a center core 1 and a clad 3, that between a peripheral core 2 and the clad 3, and radiuses of the center core 1 and the peripheral core 2 are set to proper values. The center core 1 consists of pure quartz (silica) and does not contain GeO2. Though the optical fiber is placed in atomospheric hydrogen and hydrogen molecules are diffused in the fiber, the OH radial is not generated because of the absence of GeO2. Thus, since the increase of transmission loss due to the OH radical in the 1.3mum band is prevented and there is not a problem of the increase of scattering due to GeO2, the transmission characteristic is improved in comparison with the use of conventional quartz where GeO2 is added.

IPC: H05K3/10
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To reduce the labor of a processing process and to add or correct a circuit pattern by oxidizing a part of a solid polyorganosilane thin-film containing onium salt, and doping it with oxidizing substances after that. SOLUTION: A solid polyorganosilane has a molecular skeleton composed of Si-Si bonds. The skeleton construction is not restricted specially, and either of a chain-like, branched, or reticulate one will do. But, it is desirable that a reticulate construction should be formed, considering that the polyorganosilane is solid at the normal temperature and remains solid, even if at least some Si-Si bonds out of the molecules are siloxanized by oxidation reaction, and for preventing low moleculization which proceeds with oxidation reaction. It becomes possible to form an electronic circuit by the change of an electric conductivity, by using the oxidation reaction of the polyorganosilane. It becomes possible to form a thin film in an arbitrary shape.
