Title: Optimizer for cell treating apparatus
Inventor: IMAI KATSUYUKI
IPC: G01N1/28
Filed: 1991-11-29
Abstract: PURPOSE:To enable handy and quick fine adjustment of voltage by performing a fine adjustment of voltage varying opposed areas of a pair of opposed electrodes in a liquid to eliminate the need for adjustment by moving in or out the liquid. CONSTITUTION:Coarse setting of voltage is performed with a coarse adjuster. Then, a knob 9 of an optimizer 4 is turned manually for fine adjustment to rotate electrode plates 7a and 7b in a container 5. As the electrode plates 7a and 7b are immersed into an ion water, the resistance of the optimizer 4 lowers with a mutual increase in opposed areas of the electrodes 7a and 7b in the ion water. As a result, a voltage applied to the electrodes drops. This eliminates the need for work of injecting and draining the ion water in the container 5 in the fine adjustment of the voltage by the optimizer 4 thereby achieving the fine adjustment of the voltage handily and quickly.
