Title: Pretreating method for anion analysis
Inventor: KUMAMARU NAOHIRO
IPC: G01N21/31
Filed: 1990-11-06
Abstract: PURPOSE:To analyze anions in a strong alkaline sample accurately by using an electrodialysis tank, and performing neutralization by electrodialysis. CONSTITUTION:Sample liquid passes through a sample chamber 2 from a tank 8 and returns into the tank 8. Anode liquid containing hydrogen ions is supplied into an anode chamber 1 from a tank 16. Cathode liquid is supplied into a cathode chamber 3 from a tank 9. When a current is conducted through an electrodialysis tank, the hydrogen ions in the anode chamber 1 pass through a cation exchange film 4 and moves into the sample chamber 2. Meanwhile, the cations contained in the sample liquid pass through a cation exchange film 5 from the sample chamber 2 and move into the cathode chamber 3. Therefore, the cations which are inherently present in the sample liquid are substituted by the hydrogen ions which are supplied from the anode chamber 1 with the passing of time. Thus, the sample liquid is neutralized.

Title: Micro flaw detector
Inventor: NAGAMUNE AKIO
IPC: G01N27/83
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To detect a micro flaw efficiently with high S/N ratio regardless of the traveling speed of a material to be inspected without decreasing the lift off too much. SOLUTION: A traveling object 3 to be inspected is magnetized in the traveling direction through a magnetizing unit 7. When a leakage flux caused by a micro matter present in the object 3 to be inspected passes directly under an E type magnetic sensor 1, an electric signal is outputted therefrom. Output from the E type magnetic sensor 1 is amplified electrically through an amplifier 9 and passed through a filter 10 in order to suppress noise thus enhancing the S/N ratio. It is then rectified through a rectifier 11 and the defect is determined by a decision circuit 12 which produces the results. An automatic cut-off frequency setter 13 reads in the interpole distance of E type magnetic sensor, lift off L and the traveling speed V of the object and calculates a cut-off frequency which is set in the high-pass filter 10.
