Abstract: PURPOSE:To improve sphericity of a ball unit, its uniformity and polishing efficiency decreasing dispersion of a magnetic field with a float improved in its restoring force and levitating force and eliminated in the unstability of the flat following its rotation by using a magnetic field forming means provided with two or more magnetic poles arranged with a space not more than a predetermined value alternately changing polarity. CONSTITUTION:While holding a spherical workpiece 3 in abrasive grain- contained magnetic fluid 7 by a driving lap 1, float 5 receiving levitating force by a magnetic field formed in the magnetic fluid 7 by a magnet 6 and the internal peripheral surface of a guide ring 4, the spherical workpiece 3 is polished by rotating the driving lap 1. Here the magnet 6 is formed by a strip- shaped magnet group linearly arranged in one line while changing polarity with a predetermined pitch of 10mm or less. In this way, the flat 5 increases its restoring force and levitating force and eliminates unstability of the flat following its rotation, and stably holding and guiding the spherical workpiece 3, its sphericity, uniformity and polishing efficiency can be enhanced.

Title: Contact-electrifying-means cleaner for image forming device
Inventor: TAWADA TAKAAKI
IPC: G03G15/02
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To keep the surface of a contact electrifying member, used for cleaning the surface of the photoreceptor of an image forming device, clean over a long period. SOLUTION: During image formation, the electrifying belt 7 is rotated accompanying the photoreceptor 1, and it is separated from the photoreceptor 1 by means of a DC solenoid 14 during image nonformation. When being apart from it, the electrifying belt 7 is brought into contact with an electrolytic solution and cleaning member 8, and it is rotated and driven by a motor 13 to clean its surface. Ions such as Na<+> in tap water, as the electrolytic solution, in a container 12 electrostatically attract charged toner on the surface of the electrifying belt 7 and weakens the sticking force of the toner to the electrifying belt 7, and thus the surface of the electrifying belt 7 is easily cleaned by the cleaning member 8, such as felt.
