Title: Method for recovering and purifying suspension solution and device therefor
Inventor: SHIBAYAMA YOSHIO
IPC: C02F1/60
Filed: 1993-12-27
Abstract: PURPOSE:To make a closed system, to prevent environmental pollution by recovering water mainly used in a silicone semiconductor manufacturing process from waste water and purifying it to be reused by circulation, and to provide a means for saving maintenance expenses by repeatedly using water being a solvent. CONSTITUTION:A refrigerating coil or a brine coil are directly used in a refrigerating tank 1 of about 301 capacity containing waste liquid primarily treated to cool the liquid to <=-10 deg.C. Solid matter which is frozen taking silicone particles as neuclei is taken out to transfer it to an adjacent thawing tank 2. After the solid matter is washed to remove impurities stuck on its surface, it is thawed. After that, solid matter mainly consisting of silicone particles which is classified and made coarse is separated from water in a liquid state, which is mixed in a circuit of fresh treated water to form a circuit of a closed system.

Abstract: PROBLEM TO BE SOLVED: To easily execute the liquid immersion observation of a sample without consuming much time and labor by attaching liquid to the tip of an objective lens through a hole just before the liquid immersion observation is executed by leaving the sample to be arranged at an observing position as it is. SOLUTION: The objective lens 21 is lowered and sufficiently separated from a sample stage 40. By rotating a revolver, the lens 21 is deviated from the observing position of the sample. At this time, the stage 40 is rotated so that the hole 42 is positioned on the rotating locus 21a of the lens 21. Then, a Petri dish 51 is set on the stage 40 and the observing position is specified by the low-magnification lens 21. The tip of the lens 21 is opposed to the hole 42 by rotating the revolver and the revolver is fixed at the position by a hand. Next, oil is attached to the tip of the lens 21 through the hole 112 by using a pipet 60. Then, the lens 21 is arranged at the observing position by rotating the revolver and made to approach the dish 51 so as to execute the oil immersion observation of the sample in the dish 51.  When water is attached to the tip of the lens 21, it is executed by the same process.
