Title: Automatic loop gain control device
Inventor: OGINO TSUKASA
IPC: G11B7/09
Filed: 1990-08-02
Abstract: PURPOSE:To always stable drive a servo system by providing this automatic loop gain control device with a correlation coefficient detecting means for detecting a specific correlation coefficient and a means for changing the gain of a control loop in accordance with the detecting result of the detecting means. CONSTITUTION:The output of a phase compensating filter 11 is sent to an adder 16 and added to a reference signal outputted from a reference signal generating part 17. A correlation value computing part 15 finds out a correlation coefficient between a peak value S1 outputted from a peak value detecting part 13 and a peak value S2 outputted from a peak value detecting part 19, and when the found correlation coefficient is smaller than a prescribed value, sends a prescribed attenuation rate D to a loop gain control part 20. When the correlation coefficient is larger than the prescribed value, an amplification factor computing part 14 computes an amplification factor K = S2/S1 and sends the computed result to the control part 20. Since the variation of the loop gain due to the sensitivity changes of respective elements is effectively corrected and the optimum loop gain is always held, the servo system is stably driven.

Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To obtain a purified sucrose-type liquid sugar at a low cost by filtering a crude liquid sugar containing colloidal impurities as main impurities with a charged filtration film, thereby efficiently removing the impurities dispensing with or simplifying the carbon dioxide saturation step. SOLUTION: The objective sucrose-type liquid sugar can be produced by filtering a crude liquid sugar containing colloidal impurities as main impurities with a charged filtration film coated with a charge modifier generating (+)-zeta potential on a filter material or by desalting a crude liquid sugar containing colloidal impurities, coloring impurities and salts by contacting with an ion- exchange column resin composed of a strongly basic anion exchange resin and a weakly acidic cation exchange resin and then filtering the treated liquid with a charged filtration film. Since a carbon dioxide saturation treatment can be omitted or an extremely rigorous carbon dioxide saturation treatment is unnecessary in the process, the process can be simplified and the colloidal impurities, etc., can be removed in high efficiency while reducing the unit requirement.
