Title: Thrust dynamic pressure bearing
Inventor: TAKAHASHI TAKESHI
IPC: F16C33/10
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a thrust dynamic pressure bearing which can efficiently collect lubricating fluid at a radially center portion of a herringbone-shaped dynamic pressure generation groove, and show maximum load application performance. SOLUTION: In this thrust dynamic pressure bearing, a dynamic pressure generation groove on an outer peripheral part 3A under the strongest centrifugal force has maximum depth for increasing performance of capturing lubricating fluid. A dynamic pressure generation groove on an inner peripheral part 3C under the minimum centrifugal force but requiring performance for collecting the lubricating fluid at a center portion 3B has secondly deeper depth. A groove on the center portion 3B has the least depth due to herringbone typed form of the dynamic pressure generation grooves. It is thus possible to take balance performance for collecting the lubricating fluid from the outer peripheral part 3A under the maximum centrifugal force to the center portion 3B, and collecting the lubricating fluid from the inner peripheral part 3C under the minimum centrifugal force to the center portion 3B.  The lubricating fluid can efficiently be collected to the radially center portion 3B of the dynamic pressure generation groove 3.

Title: Means for attaching and detaching bobbins
Inventor: TSUKUMO ZENZABUROU
IPC: B65H67/06
Filed: 1981-10-08
Abstract: PURPOSE:To provide easy means for attaching and detaching bobbins to and from auto-doffers in which bobbins are held suspended by energizing and deenergizing a solenoid to move an inner core rod up and down thereby causing the balls supporting the bobbin to move into or out of place. CONSTITUTION:When the iron core 7 within the case 3 is magnetized by magnetizing means, the iron core 7 attracts the iron piece 8 in opposition to the force of the spring 4 so that said iron piece is pressed against the integrated head 5' of the inner core rod 5, which in turn is moved downward. Thus the end of the inner core rod 5 pushes the ball 1 outward through the hole 2 in the case 3, thereby permitting the bobbin to be detachably and self-aligningly supported in the internal diameter of the hole on its top so that the bobbin can be held in the suspended position. Next, when the iron core 7 is demagnetized, the inner core rod 5 is pushed upward by the force of the spring 4 and consequently the ball 1 is allowed to move back in place in the hole 2 in the case 3.
