Title: Substrate processing equipment and substrate processing system
Inventor: SATO MASANOBU
IPC: H01L21/68
Filed: 2002-10-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide substrate processing equipment and a substrate processing system in which a substrate can be processed well by effectively preventing the mist generated in processing from adhering to the other major surface of the substrate.  <P>SOLUTION: Since atmospheric gas is fed into a space SP formed between an atmosphere interrupting member 2 and a substrate S, the space SP has a positive pressure as compared with the circumference of the substrate (mist scattering atmosphere) and thereby intrusion of mist to the other major surface S2 side of the substrate SP is prevented effectively. Furthermore, the micro gap CL between the circumferential edge of the atmosphere interrupting member 2 and the substrate S is set in the range of 0.3mm-1mm. Consequently, mist can be prevented from leaking through the micro gap CL while stabilizing the attitude of the substrate S. When the interval is set in the range of 0.3mm-0.8mm, atmospheric gas supply into a micro space SP is suppressed and the attitude of the substrate is stabilized furthermore. Consequently, the substrate can be processed at a low running cost.  <P>COPYRIGHT: (C)2004,JPO

Title: Disk player improvement
Inventor: SHEPHERD DAVID
IPC: G11B33/12
Filed: 2002-11-12
Abstract: <P>PROBLEM TO BE SOLVED: To provide a disk player that can be miniaturized and manufactured at reduced cost.  <P>SOLUTION: The incorporation of an integrated damping system 13 within the base of the disk player eliminates the requirement for the manufacture and assembly of separate rubber AV mounts. Additionally, because the damping system 13 is integrated with the base, the allowed clearance between the disk and the inner surface of the base can be reduced. This reduction enhances the miniaturization of the dimensions of the disk player. As a direct result of this miniaturization, the overall wind drag experienced by the disk is reduced, resulting in reduction in the current required to drive the spindle motor. An obvious advantage of this will be an increase in the lifetime of battery cells employed by portable disk players.  <P>COPYRIGHT: (C)2003,JPO
