Filed: 1984-04-11
Abstract: PURPOSE:To make stably a low-price steel sheet usable by providing a stepped part close to the cut part of a plastically-worked steel sheet and changing a residual stress in the circumference of a step-pushing part into a different kind of stress. CONSTITUTION:The inner diameter of a hole is secured accurately by using a boring tool 16 and a step-pushing die 17 in one body, for working a material in a state that the tool 16 is inserted in the hole before the die penetrates into the material. Because an inner surface part 15 receives a force, tending to move the material structure, by the step-pushing work, it produces a stress different in kind from a residual stress of drawing work, existing in the periphery of step- pushing part. Accordingly, a state almost free from the effect of residual stress of drawing work is produced in the inner-surface part of step-pushing part. As mentioned above, a low-price material can be used for a closed-vessel material without causing a crack at the time of pipe welding.

Title: Divider of magnetic bubble
Inventor: IKEDA HITOSHI
IPC: G11C11/14
Filed: 1985-04-05
Abstract: PURPOSE:To divide a magnetic bubble by a relatively small current by providing an island-shaped ion implantation area between major line formed by implantation of bead-shaped ions and a minor loop. CONSTITUTION:A margin circuit is formed between a minor loop 9 formed by implantation of bead-shaped ions and a major line 10, and an island-shaped non- ion implantation area 11 is provided across a gap with the width of a diameter of a magnetic bubble 1. When a current is impressed to a conductor 12 at the time of arrival of the bubble 1 to a corner of the loop 9, the bubble 1 is stretched along the gap so as to be the sneak-shaped magnetic domain 6. As a phase of a rotational magnetic field 14 advances, it becomes the sneak-shaped magnetization and stable. After this, when the current is cut off, some part of the magnetization 7 intersects with the conductor 12 orthogonally or obliquely, and divided into two parts by a reverse current. They will not reverse owing to the margin circuit, and one of them and the other are transferred to the loop 9 and the line 10, respectively. Thus the stretched magnetic bubble will not pass through the non-ion implantation area, and can be divided by a small current.
