Title: Formation of single-crystal magnesia spinel film
Inventor: TAGUCHI EIJI
IPC: H01L21/205
Filed: 1989-08-08
Abstract: PURPOSE:To form a single-crystal MgO.Al2O3 film having a flat surface and good crystallinity by controlling the concentration of reaction gas H2 to obtain a growth rate at which a laminar growth of single-crystal MgO.Al2O3 film takes place. CONSTITUTION:When a single-crystal MgO.Al2O3 film is grown on a single crystal Si layer 8 by vapor-phase epitaxy using MgCl2, AlCl3, CO2, and H2 for reaction, the concentration of H2 is controlled to obtain a growth rate at which a laminar growth of a single crystal MgO.Al2O3 film takes place. For example, an Al source 5, MgCl2 6, and an Si substrate 8 are heated and maintained at 650 deg.C, 900 deg.C, and 950 deg.C, respectively, in furnaces 7-9, while a mixture of HCL and N2 is introduced through a tube 3, N2 through a tube 4, a mixture of CO2, N2, and H2 through a tube 2. Then, the concentration of H2 to be fed into a reaction tube 1 is restricted to be about 10% or less to keep the growth rate of the single crystal MgO.Al2O3 film below 10Angstrom /min.

Title: Automatic copying device of welding
Inventor: WADA KOUICHI
IPC: B23K9/127
Filed: 1982-11-24
Abstract: PURPOSE:To perform adequately automatic welding in a narrow part by exciting a copying roll and providing a restoring characteristic to a weld line by making use of the floating when the roll is excited. CONSTITUTION:When the copying position of a copying roll 13 deviates, the roll is oscillated by an exciter 17 and therefore a welding torch 12 is pressed to a frame body 11 and rotates around a rotary joint 22. The rotating amt. of the joint 22 is detected with a displacement detector 24, and a driving motor 26 operates in accordance with the signal of said detector. When the center of the excitation moves, the roll 13 floats from the body 11; at the same time, the roll is moved to rotate around a contact point 16 by the energizing force of a spring 19, by which the central position of the torch is lowered. The roll 13 is finally brought into uniform contact with the body 11 by the operation of the next excitation cycle. In other words, the effect of restoring the position to the prescribed welding center is obtd. even if the roll 13 deviates in copying to the right or left direction.

Title: Superconducting magnet apparatus
Inventor: KIMURA SHINICHI
IPC: H01F6/04
Filed: 1988-08-22
Abstract: PURPOSE:To avoid vaporization of liquid coolant near a coil caused by radiant heat by a method wherein a liquid coolant container is composed of a double structure and holes are provided at the vapor phase part and the liquid phase part of a liquid coolant container inner chamber respectively. CONSTITUTION:A liquid phase hole 10a and a vapor phase hole 10b are provided at the lower part and the upper part of a liquid nitrogen container inner chamber 10 respectively. As the liquid nitrogen container inner chamber 10 is linked with a liquid nitrogen container outer chamber 11 by the liquid phase hole 10a and the vapor phase hole 10b, the surface levels of liquid nitrogen 4 of both the chambers are always the same. Therefore, as the liquid nitrogen always exists around the liquid nitrogen container inner chamber 10, heat penetration caused by radiation can be avoided. Radiant heat penetrating into the liquid nitrogen container outer chamber 11 from a vacuum container 5 vaporizes the liquid nitrogen 4 in the outer chamber and produces bubbles. the bubbles ascend through the liquid nitrogen in the outer chamber to the vapor phase part of the outer chamber 11 and flow into the vapor phase part of the inner chamber 10 through the vapor phase hole 10b and recovered out of the apparatus through a nitrogen gas port 9b. With this constitution, bubbles are not produced in the inner chamber by radiant heat and the degradation of the cooling effect of a superconducting coil 2 can be avoided.

Title: Picture reading method and device therefor
Inventor: YAMAZAKI YOSHIAKI
IPC: H04N1/04
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To provide a picture reading method which enables highly precise picture reading without causing a problem that a color muddiness is generated by adjusting a light amount balance of a sensor system that composes a scanner and keeping its balance for each color of the amount of light made incident to the scanner in accordance with the kind of an original. SOLUTION: At a scanner 12, a reading light emitted from a light source 22 has a whole light amount adjusted by a variable diaphragm 24, then a color is adjusted in accordance with the kind of an original by a light amount adjustment filter 26. That is, even if the original kind changes, few deviations occur in the light amount among colors, or it is constituted so that the light is made incident to each line CCD sensor 34 of R, G and B of a CCD sensor 34 after the adjustment is performed to suppress the deviation. Thus, it is possible to resolve one frame picture into three primary colors of R, G and B by the CCD sensor 34 and to simultaneously read it by the reading light where an incident light intensity to each line CCD sensor of R, G and B balances among colors.

Abstract: PURPOSE:To improve the fluid efficiency of a turbine by installing a shaft whose one end is locked on the center of gravity of the airfoil of a rotor blade and the other end is rotatably held on the rotor so that it can be prevented from slipping out. CONSTITUTION:A rotor blade 12 is installed on the perimeter of a rotor 11 and a shaft 13 whose one end is locked on the center of gravity of airfoil of the rotor blade 12 is rotatably held on the rotor 11 at the other end so that it can be prevented from slipping out. Thus, since the shaft 13 around which the rotor blade 12 can rotate at the center of gravity of airfoil, can be held only by the rotor 11, the fluid efficiency of the turbine can be increased, reducing the flywheel effect of the rotor rim.
