Title: Disk recording system
Inventor: TSUKIHASHI AKIRA
IPC: G11B7/0045
Filed: 1999-07-21
Granted: 2001-05-28
Abstract: When a buffer underrun decision circuit (17) decides that a buffer underrun is about to occur, data recording on the disk is interrupted by a recording control circuit (18). On the other hand, when the buffer underrun decision circuit (17) determines that a buffer underrun situation has been avoided, data recording is resumed by the recording control circuit (18). At this time, data recording is resumed from a position of the disk which is continuous to data recorded by the time the data recording was interrupted, thereby recording new data continuous to the last recorded data.

Title: Method of improving loading effect in wet oxidation process
Inventor: YE SHU-YOU
IPC: H01L21/31
Filed: 1999-11-02
Granted: 2001-03-01
Abstract: The present invention provides a wet oxidation process which is applicable in a furnace so that a silicon oxide layer is formed on a semiconductor chip in the furnace. The method comprises performing a main oxidation step and an auxiliary oxidation step. When performing the main oxidation step, the partial pressure of H2O gas is a first H2O partial pressure to form a silicon oxide layer on the semiconductor chip. When performing the auxiliary oxidation step, the H2O gas partial pressure is a second H2O gas partial pressure that is lower than the first H2O gas partial pressure to dilute the H2O gas in the furnace, and continue increasing the thickness of the silicon oxide layer. The auxiliary oxidation step can reduce the difference in the thickness of the silicon oxide caused by different closing speed of the flowrate valve for the H2O gas, thereby improving the loading effect of the wet oxidation process.

Abstract: A disposable solder receiving capsule for a hand held vacuum solder extracting desoldering tool is formed of an outer tube which is closed at one end by a porous filter and has an opening at its opposite end, and a hollow solder collection chamber part, having a tubular member with an open end and which is closed with respect to the passage of solder therethrough at an opposite end, forming a solder receiving space within it. The solder collection chamber part is concentrically positioned within the outer tube with an air plenum disposed between the closed end of the chamber part and the filter and with at least one air channel extending the length of solder collection part for providing a path for gases entering the open end of the outer tube to the plenum and the filter that is separated from the solder receiving space. For facilitating solder reclamation, the capsule can be formed entirely of materials which are shape-sustaining when exposed to a temperature of 400 DEG F, are not reactive with either solder and flux, which will burn with little or no residue at a temperature less than 800 DEG F. A desoldering tool for use with the capsule has a detachable, tubular capsule holding part that is open at each of its opposite ends for enabling a solder receiving capsule received in it to be removed from one of the end of the holding tube by pushing another soldering capsule into the opposite end of the holding tube when the detachable holding part is detached from the body of the desoldering tool. In a most preferred embodiment, the tool is designed so that solder cannot be drawn into it if the capsule has not been inserted or has been inserted incorrectly.
