Title: Manufacture of fe-b-r based permanent magnet
Inventor: YAMASHITA FUMITOSHI
IPC: H01F41/02
Filed: 1988-06-21
Abstract: PURPOSE:To obtain an excellent Fe-B-R based permanent magnet by adding one-axis pressure and a current to the collected body of Fe-B-R based thin pieces in an unbalanced state, thereby obtaining a high density sintered body. CONSTITUTION:Fe-B-R based thin pieces (R represents one or two or more kinds of rare earth elements incorporating Y) in an unbalanced state which commonly have an R2Fe14B phase and an amorphous phase are filled in a cavity. One-axis pressure and a current are added, and Joule heat is generated at the contact interfaces between the thin pieces. Thus, atomic bonding at the contact interfaces is achieved. The Joule heat is absorbed into the inner part from the surface layer of each thin piece. Thus the surface layer of each thin piece is quickly cooled. In this way, a high density sintered body is obtained, and the excellent Fe-B-R based permanent magnet is obtained.

Title: Centrifugal propulsion speed change pulley
Inventor: TAKANO HIROSHI
IPC: F16H55/56
Filed: 1986-06-30
Abstract: PURPOSE:To improve the efficiency of centrifugal function, by arranging supports for providing centrifugal propulsion respectively to a movable V-pulley chip and a spring stopper integral with the shaft then mounting a plurality of movable members for providing the centrifugal force in a space formed by them. CONSTITUTION:In a speed change pulley, centrifugal force providing members 6, e.g. a plurality of balls, are approximately filled in a space when the rotation is low so as to balance the centrifugal thrust produced by rotation and the returning thrust of a push spring 5. When the rotation increases and the centrifu gal thrust exceeds over the thrust of the push spring 5, a movable V-pulley chip 2 moves in the direction separating from a fixed V-pulley chip 1 so as to reduce the effective diameter of a belt 7. Since the centrifugal force providing members 6 can occupy a large part in the space, a larger thrust can be obtained thus enabling usage with low rotation or small pulley diameter. Consequently, the thrust can be adjusted automatically according to the rotation of pulley.
