Title: Magnetic floating type conveyer
Inventor: MINAMINO IKUO
IPC: H01L21/677
Filed: 1987-10-26
Abstract: PURPOSE:To stably support a conveyed object by constituting a device restricting rotation of a conveying shaft or driving it by a conveying shaft member rotary restricting means so as to generate its acting force obtaining only a component of the shaft member in its direction of rotation, in case of the captioned conveyer for a semiconductor manufacturing device or the like. CONSTITUTION:When a conveying shaft member 57 rotates, a rotary control means 75 controls electromagnets 76-79 by a change of impedance due to rotation of a stepped part 57c, and generating magnetic force so as to return the conveying shaft member 57 in its rotation to the original position, the stepped part 57c is restricted so as to stop in the width center in point end parts of the electromagnets 76-79. Here generating magnetic force F by a difference between flows of electric current in each pair of the electromagnets 76 and 78, 77 and 79, the rotation is restricted by generating an intensity difference in the magnetic force F. Here the magnetic force F generates a component FA in a direction of rotation and a component FB in a radial direction, but the component FB in the radial direction is canceled because it is in an opposite direction in each paired electromagnet, and no displacement is generated in the radial direction. Thus the conveying shaft member enables its vibration to be prevented.
