Title: Mixing valve device
Inventor: SEKOGUCHI KOTOHIKO
IPC: F16K11/10
Filed: 1987-04-23
Abstract: PURPOSE:To produce mixed liquid having constant temperature regardless of pressure variation of cold liquid, in a mixing valve device for mixing steam with cold liquid to produce mixed liquid having predetermined temperature, by arranging a pilot valve body at the upstream side of a valve seat. CONSTITUTION:Control pressure is transmitted by a pilot valve V3 into a pressure-sensitive chamber for driving a valve body which controls steam flow and cold liquid flow through pilot paths R1-R3. A spherical pilot valve chip 40 is energized by a valve spring 39 through a micro gap L in the direction of a valve seat. The pilot valve 40 is operated by a temperature sensitive moving chip 9, where the micro gap L decreases when the temperature sensitive movable chip 9 moves to high temperature side X while decreases when the chip 9 moves to low temperature side Y. Consequently, even when the pressure of cold liquid increases to cause pressure rise in the pilot path R3, the pilot valve chip 40 is pressed by the liquid pressure so as to reduce the micro gap L and maintain the pressure in the path R3 constant thus causing no temperature variation of mixed liquid.

Title: Method of polishing semiconductor wafer
Inventor: UEMATSU EI
IPC: B24B55/12
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent the clogging of a grinding wheel by performing a grinding while spraying water to the grinding wheel. SOLUTION: A nozzle is mounted within a grinding machine, so that the grinding surface of a grinding wheel can be washed every time during the carrying of a wafer after grinding. To prevent the clogging, it is necessary to remove the chip adhered to the grinding wheel every grinding. Although the adhered chip can be removed by periodically dressing the grinding wheel by use of a dress board, the periodic dressing results in the shortening of life of the grinding wheel because the dressing means the shaving of the grinding wheel. As the method for removing the chip without shortening the life of the grinding wheel, it is effective to spray high-pressure water to the grinding surface of the grinding wheel. Accordingly, the grinding wheel is washed with high-pressure water every grinding, whereby the clogging of the grinding wheel can be prevented.
