摘要： PROBLEM TO BE SOLVED: To enhance the uniformity in polishing of a wafer surface by preventing a polishing pad from undulate deformation. SOLUTION: A wafer polishing head H is equipped with a head body 1 consisting of a top plate 1a and circumferential wall 1b, a diaphragm 2 installed stretching inside the head body 1, a carrier 3 to displace a wafer W in association with deformation of the diaphragm 2, a retaier ring 4 fixed to the udersurface of the diaphragm 2 and arranged displaceably in compliance with the deformation of the diaphragm, and a pressure adjusting mechanism 5 to deform the diaphragm 2 in the head axial direction L, wherein between the head body 1 and diaphragm 2, a spacer is removably interposed in such a way as constituting a flange. This reduces the pressure acting on a polishing pad P through the retainer ring and prevents the polishing pad P from undulate deformation.

摘要： PURPOSE:To provide a bearing device having less friction, abrasion, vibration and noise, and having a high durability, by providing a radial magnetic support part composed of cylindrical and ring-like magnets, and a thrustwise mechanical support part for supporting an end part of a rotary shaft. CONSTITUTION:In a bearing device 110, a magnetic field indicated by magnetic force lines 410 is generated by a ring-like magnet 22. A cylindrical magnet 221 is located in the magnetic field, having an S pole surface facing that of the ring-like magnet 222. A magnetic force 420 going into the ring-like magnet 222 along the magnetic force lines 410 acts upon the S pole surface of the cylindrical magnet 221. Meanwhile, a magnetic force 430 going away from the ring-like magnet 222 along the magnetic force lines 410 acts upon the N-pole surface of the cylindrical magnet 221. By the way, the magnetic field has its strength which is maximum in the ring-like magnet 222, and which decreases as it goes outward from the magnet 222, and accordingly, the magnetic force 420 is greater than that of the magnetic force 430. As a result, the force going into the ring-like magnet 222 acts upon the cylindrical magnet 221.
