Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To solve any rolling stoppage of a container in an automatic manner by installing a rock driving part for imparting such a motion as rocking in an interval between a stationary position and a push-in position to the rail central side, in a rail. SOLUTION: In the case where a drum can (d) takes its oblique course and it is stopped after being contacted with the flange of a rail 1, a camshaft 10 is rotated as far as 180 degrees, and a connecting rod 8 is moved to the left in the maximum by dint of an eccentric cam 9. With this, the rail 1 gets tilted to the right with a rocking fulcrum W as the center, whereby the rail flange pushes the drum can (d) therein. Simultaneously the rail at the opposite side performs a symmetrical push-in operation as well, thrusting the drum can (d) into the central side.  Successively the cam 9 is restored to the original position by dint of rotation of the camshaft 10, restoring the flange of the rail 1 to its vertical position again, and a position of the thrust drum can (d) is corrected in the center direction, and thus any contact with the rail flange is set free, and readvancement is performed by means of rail inclination.

Title: Preparation of thin belt of permanent magnet
Inventor: SAHASHI MASASHI
IPC: H01F1/04
Filed: 1982-04-21
Abstract: PURPOSE:To prepare a thin belt of permanent magnet which is excellent in magnetic property, surface smoothness and flexibility by such an arrangement wherein molten liquid of Fe-Cr alloy or Fe-Cr-Co alloy is processed by alpha single phase treatment under specific conditions and at the same time it is formed into a thin belt, and after that the belt is processed by ageing treatment. CONSTITUTION:When molten liquid of adjusted Fe-Cr alloy or Fe-Cr-Co alloy is spouted onto the rotating surface of a drum or roll which is rotated at a peripheral speed of more than 1m/sec, the molten liquid becomes a thin belt as it is quickly cooled and solidified. A cooling speed of more than 1,000 deg.C/sec is necessary and if it is less than that, it is difficult to pull out phase in single phase condition to a room temperature. An alloy consisting of 30wt% Co, 25.0wt% Cr and the residue of Fe is put in a quartz container equipped with a nozzle at its top end, and it is melted in argon atmosphere by high frequency induction heating method, and the molten liquid being applied with gas pressure is caused to spout onto the rotating surface of a single sided roll made of copper from the nozzle. The crystal construction of a thin belt to be obtained by a peripheral speed of 15m/sec and cooling speed of 100,000 deg.C/sec is alpha phase of single phase which is verified by X ray diffraction method. A thin belt of permanent magnet can be obtained by processing the thin belt by ageing treatment in a magnetic field.
