Title: Centrifugal cleaner
Inventor: ITOU KIYOSHI
IPC: B30B9/02
Filed: 1979-01-26
Abstract: PURPOSE: To permit easy disassembling of the rotator liquid-contact part of the centrifugal cleaner by reducing the pressing force between the pole hood for holding a separating plate and its lock ring thereby making the lock ring easier to turn.  
     CONSTITUTION: A hermetic space 18 is formed between the cover 11 fixed to a separating plate holder 3 by way of a guide spindle 6 and a piston 9 having a ring weir part 12. To disassemble the rotator liquid-contact part, air of a suitable pressure is introduced into the space 18 through an air feed pipe 23 to mutually expand  the spacing between the cover 11 and piston 9. A separating plate 1 is then pushed  downward and contracted by the piston 9 by way of a pole hood 4 to annihilate  the elastic repulsive force of the separating plate which has acted upon the lock  ring 5 by the pole hood 4. Hence, the galling of the thread part of the lock ring  5 is decreased. A removing tool is applied to the engaging groove 27 of the lock ring 5 and is lightly tapped, then the ring 5 readily loosens and by removing this, the rotator liquid-contact part may be readily disassembled.

Abstract: PURPOSE:To efficiently generate a long plasma channel by focusing laser beams at continuous focal points or discontinuous focal points on the optical axis without affecting each other. CONSTITUTION:Focal points f1-fn of a concave mirror 1 exist continuously on the optical axis 2, a laser beam 3 reflected at a near portion in the radial direction from the optical axis 2 of the concave mirror 1 forms a focal point on the optical axis 2 near the concave mirror 1, and a laser beam 3 reflected at a far portion in the radial direction forms a focal point on the optical axis 2 far from the concave mirror 1. For the shape of the curved surface of the concave mirror 1, the function f(r) of the curve along the radial direction is expressed by the equation, where (r) is the distance from the center of the concave mirror 1, and alpha, beta are positive constants regarding the focal distance. When beams 3 parallel with the optical axis 2 are fed to the mirror 1, the beam 3 fed at a portion near the center of the mirror 1 is focused on the optical axis 2 near the mirror 1, and the beam 3 fed at a portion far from the center is focused on the optical axis 2 far from the mirror 1. When the intensity distribution of the beams 3 at the focus portions becomes a fixed value or above, a plasma channel 4 is generated over the whole portions.
