IPC: B04B9/12
Filed: 1983-11-21
Abstract: PURPOSE:To make it possible to rotate a vertical shaft in a vacuum molecular turbo- pump, etc. at an ultra high rotational speed, by rotatably supporting the vertical shaft by means of bearings so that the lower end of the vertical shaft is attached immovably in a horizontal plane to a base bed, and the other end of the vertical shaft is swingably attached to the base member. CONSTITUTION:A vertical rotary shaft 4 is pulled up by the attraction force effected between both magnets 11, 12 so that a ball bearing 8 is subjected to only a slight load equal to the difference between the attraction force and the total weight of the shaft 4, an armature 5 of a motor, movable blades 6, the magnet 12, etc. Further, the borh magnets are coaxially positioned so that the confonting areas of both magnetis take a maximum value. Therefore, by making small a gap 16 between a hole in a floating bed 10 and a pin 15, the shaft 4 is held in a substantially vertical posture. When a motor 5 is started, even if the shaft 4 is inclined, the shaft 4 stands upright under the principle of a top having a bearing as a fulcrum, being accompanied with the rise of rotational speed, and carries out a small differential motion having a slight inclined angle due to the difference between the gravitational center and the center line of the shaft 4. Further, the floating bed 10 carries out a circular motion having a small diameter on a flange 13. With this arrangement no strict dynamic balance is required, and as well an ultra high speed rotation may be effected.

Abstract: PROBLEM TO BE SOLVED: To prevent the transfer of silicate ions to a concn. chamber through an anion exchange membrane, to suppress the generation of scale and to enable long-time continuous operation by adding dipolar ions to an aq. alkali silicate soon. and electrodialyzing the soln. SOLUTION: Dipolar ions of an element such as Al, Zn, Pb or Sn, preferably Al are added to an aq. alkali silicate soln. When Al ions are added, aluminum hydroxide or aluminum oxide may be used as a source of Al. The concn. of the dipolar ions in the aq. alkali silicate soln. is preferably 60-620 ppm. Since it is provable that the dipolar ions and silicate ions in the aq. alkali silicate soln. form a certain complex or clathrate compd., the silicate ions are made less liable to pass an anion exchange membrane. The aq. alkali silicate soln. is then electrodialyzed to obtain the objective dealkalized silica sol.
