Inventor: TOGO TORU
IPC: C23F1/46
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To regenerate an etching solution without polluting working environment. SOLUTION: An electrolytic cell 3 having anode chambers 9a, 9b and a cathode chamber 10 segmented by cation exchange membranes 8a, 8b. An aq. proton donative electrolyte soln. such as dilute sulfuric acid, is supplied to these anode chambers 9a, 9b and the etching solution contg. cupric chloride and hydrochloric acid is supplied to the cathode chamber 10. When a DC voltage is impressed between the anode chambers 9a, 9b and the cathode chamber 10 by a power source 5, copper precipitates on the cathode 11 of the cathode chamber 10 and the chlorine ions in the cathode chamber 10 forms hydrochloric acid by reacting with the hydrogen ions permeated through the cation exchange membranes 8a, 8b. As a result, the concn. of the copper ions in the etching solution decreases, the concn. of the hydrochloric acid increases and the etching liquid is regenerated.

Filed: 1990-07-17
Abstract: PURPOSE:To precisely detect whether or not the operation of control rods is normally executed by providing an arithmetic means to predict control rod position and a comparison means to compare an accordance with the predicated control rod position and indicating the comparison result. CONSTITUTION:This device is provided with an arithmetic means 7a to predict control rod position by inputting a control rod operation command 100, a comparison means 7b to compare the accordance of an actual control rod position input as an actual control rod position signal 103 and the predicated control rod position which is predicted by the said arithmetic means 7a. These two means form a control rod position predication and judgement part 7. An indicator 8 to indicate the result of comparison by the control rod position prediction and judgement part 7 is also provided. If the predicted control rod position and the actual control rod position disagree as the result of comparison, it is judged whether the control rod did not operate by some event or it moved too much. By this, whether the control rod operation was executed or not is precisely detected and thus safety is improved compared with the conventional method.
