Title: Method for polishing silicon wafer
Inventor: KOMURA TOMOYOSHI
IPC: B24B37/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent contamination on the surface of a silicon wafer due to metal impurity, by using colloidal silica particles obtained by causing methyl silicate refined by distillation to react with water using ammonia as a catalyst in a methanol solvent, and setting the long diameter/short diameter ratio of the colloidal silica particles at a specified or higher value. SOLUTION: Colloidal silica is used which is obtained by causing reaction between methyl silicate of an ultra high purity from which metal impurity such as iron, nickel, chromium, aluminum, copper or the like is removed by single distillation with reflux or continuous distillation with reflux and water with ammonia or ammonia and aluminum salt as a catalyst in a methanol solvent, and the long diameter/short diameter ratio of the colloidal silica particle is set at 1.4 or higher. In this case, the content of metal impurity in methyl orthosilicate is as follows: iron is less than 1.0 wt.ppb, chromium is less than 0.2 wt.ppb, nickel is 0.1 wt.ppb or less, aluminum is less than 0.5 wt.ppb, and copper is 0.2 wt.ppb or less.

Filed: 1994-01-28
Abstract: PURPOSE:To restore picture data of plural color components with one block as the unit by extracting code data related to the lightness, the structure, and the color of each block from received code data and restoring respective code data. CONSTITUTION:An inputted RGB signal is temporarily stored in a 4-line buffer 301 and is read out in the 4X4 size to segment blocks.

Blocks of L* are orthogonally transformed by an orthogonal transformation part 304 to output a lightness signal L and a structure signal S through quantizers 307 and 309. Blocks of a* and b* are averaged in average circuits 311 and 312, and they are collectively quantized to color information C by a quantizer 313. A multiplexer 315 collects signals L, S, and C into one code to output an efficiently compressed encoded code. This encoded picture data is decoded to restore picture data of plural color components with one block as the unit.

Abstract: PURPOSE:To prevent a serious accident with a hydraulic driver for a main steam stop valve, by providing a limit switch which performs action below the overtravel at the time of entire closure, to detect the rupture of the valve spindle in testing and after starting. CONSTITUTION:When a solenoid valve 12a is energized, compressed air is introduced into the upper part of a cylinder 12c to push a pilot valve 12d down. At that time, control oil 10 flows from a port 10b to another 10a and is released out of the cylinder 12c to entirely close an accessory valve 1 and a main valve 1. As a result, an entire closure indication limit switch 21 performs action if a valve spindle 3 is normal. If the valve spindle 3 is ruptured, an oil cylinder descends below an entire closre position A and the valve spindle rupture indication limit switch 21 performs action. According to this constitution, the abnormality of the valve spindle 3 is detected from the fact that the limit switch 21 is acting in the testing of operation of before the starting of a turbine.
