Title: Gas pressure-welding method of steel pipe
Inventor: ISHIKAWA YASUSHI
IPC: B23K20/00
Filed: 1979-05-02
Abstract: PURPOSE: To improve temperature distribution and form always proper reinforcement of weld and penetration by providing collars of good heat conductivity and large heat capacity near the butt ends of steel pipes and gas pressure-welding the ends.  
     CONSTITUTION: A pair of collars 15 such as copper of good heat conductivity and large heat capacity are mounted on both sides of the butt parts of steel pipe ends 1', 2' in such a manner that their tapered parts oppose to each other. Thence, when they are heated by a burner 8, a flame 11 contacts the uncovered steel pipe ends 1', 2', thereby heating these. As a result of this, in the temperature distribution near the joint ends, the temperature differences in the thickness (t) direction become less and the width of the high-temperature portions in the axial direction becomes less as shown by isotherms 14. When the pipe ends 1', 2' are pressed by hydraulic cylinders upon reaching the proper temperature, the metal at the butt portions is forced in the thickness (t) direction. At the same time, the escaping amount of the metal increases in the outer side of the pipe and decreases on the inner side because there are temperature differences in the thickness (t) direction. As a result of this, no build-up part and penetration are formed and the good joint shape is obtained.

Abstract: PURPOSE:To exactly evaluate an optical characteristic of a circuit to be measured by bringing a propagation light of a specific branch path to phase modulation in the circuit, and extracting a phase modulation component from intensity of a multiplexed light of a back scattering light generated in the circuit and a reference light. CONSTITUTION:A luminous flux from a light source 1 is divided by a half mirror 2, one luminous flux is made incident on a circuit 4' to be measured, and the other is reflected by a total reflecting mirror 5 and multiplexed with a backscattering light generated in the circuit 4', as a reference light. Also, a light beam propagated along a specific branch path 20a in the circuit 4' is brought to phase modulation by a CO2 laser 11, a lens 12 and a beam chopper 13. Also, the multiplexed light is converted to a voltage being proportional to the light intensity by a photodetector 7, and a specific frequency component generated by the phase modulation set in advance is extracted by a selection level meter 8. From the light intensity of this specific frequency component, an intensity distribution of the backscattering light is measured. With regard to each branch path of the circuit 4', as well, the intensity distribution of the backscattering light is measured separately in the same way.

Title: Magneto-optical recording medium
IPC: G11B11/10
Filed: 1992-03-13
Abstract: PURPOSE:To enable ultrahigh density recording to be conducted by using an alloy consisting of a Co-based alloy and at least one element selected from element group of Nd, Pr, Sm, Ce, Gd, Tb, Dy and Ho as a recording material. CONSTITUTION:The recording film of this magneto-optical recording medium is a perpendicularly magnetizable film and is preferably amorphous. When the film is made of an alloy consisting of Co and a heavy rare earth element such as Gd, Tb, Dy or Ho the magneto-optical effect is reduced in accordance with the shortening of wavelength used. When the film is made of a Co alloy contg. a light rare earth element such as Nd, Pr, Sm or Ce, the magneto-optical effect is enhanced. Since the prependicularly magnetizable film is hardly obtd. with a Co alloy contg. only a light rare earth element, a Co alloy contg. both heavy and light rare earth elements in a balanced state is used. High density recording with light having short wavelength is attained.
