摘要： PURPOSE:To obtain a connection section with the stably high probability that filaments meet by exposing superconductive filaments and dividing them in multiple groups and connecting a bundle of the superconductive filaments braided with these groups by solid phase connection or spot welding. CONSTITUTION:End sections of superconductive cables A, B are etched to expose superconductive filaments. They are then equally divided in three groups, e.g., a filament group (a) belonging to the superconductive cable A, a filament group (b) belonging to the superconductive cable B, and a filament group C belonging to the superconductive cables A, B. These three groups (a)-(c) are braided in turn, and the integrated filament bundle is solid phase-connected or spot-welded in the range of the connection length 11. The positional relationship among the three groups (a)-(c) is changed in the range of the connection length 11, thus the filaments of the groups (a)-(c) meet with the same probability. The meeting probability is thereby increased, and a stable connection section of superconductive cables is obtained.

摘要： PURPOSE:To improve the strength, by abutting a cylinder, to which a non- magnetic plate of high strength and a magnetic plate of high strength are combined by welding, against the outside circumference of a permanent magnet and by integrating it in diffused junction by an isotropic pressing method. CONSTITUTION:A non-magnetic plate 5 such as of stainless steel, etc., and a magnetic plate 4 made of alloy steel having about the equal strength are combined into a cylinder by welding. The magnetic plate 4 is abutted against the outside circumference of a permanent magnet 2 and is axially extended to form a space around the permanent magnet 2 with the remaining part of the opposite surface to a rotor core covered with the non-magnetic plate 5. This space is filled with non-magnetic substance powder 3. The circumference of the above first cylinder 6 is covered and sealed tightly with the second cylinder 7 made of mild steel. The tightly sealed half-assembled rotor is pressed and heated by a hot isotropic pressing method to strengthen each member by diffused junction. After that, the second cylinder is cut and removed. The permanent magnet 2 is then magnetized.

摘要： PURPOSE:To provide an improvement in joint strength, etc. by working preliminarily the inserting and joining part of the 1st work piece to a convergent taper surface of a prescribed angle and forming a rugged part on the tapered surface. CONSTITUTION:The convergent tapered surface is formed to the top end of the bar-shaped first work piece 5 at 10-30 deg. angle of inclination and plural annular rugged parts are formed thereto. The 1st work piece 5 is chucked to a spindle 11 and the 2nd work piece 8 is clamped 12 and is disposed to face the 1st work piece. A cylinder device 13 is operated to move a slider 15 in an arrow direction while a spindle 11 is rotated at a prescribed speed. The rotation of the spindle 11 is stopped and the work pieces are press-welded by the cylinder 13 when the work pieces 5, 8 melt partly. The contact area of the joint part is increased by such method and therefore the joint strength of frictional press welding is improved and the quality of the product is stabilized.
