Abstract: PURPOSE:To vary a proportion band and control cycles independently by obtaining a pulse width signal by comparing the AD conversion value of deviation passed through an ampoifier, having a variable degree of amplification with the count value of the output of a variable-frequency pulse generator. CONSTITUTION:The output of a detector S is sent to a comparing circuit 3 through a conversion unit, and its deviation from the set value of a potentiometer 2 is sent to an absolute-value circuit 4 and a positive and negative discriminating circuit (consisting of elements 14-17). The output of the absolute- value circuit 4 is sent to an AD converter 6 through an amplifier 5 to be inputted to one-side terminals of comparators 11-13. As the other input signals, the  outputs of counters 8-10 which count the output of an oscillator 7 are sent, and gates 19 and 20 are opened by their coincidence signals. The gates 19 and 20 input the positive-negative signal of a deviation signal to control the discharge  of cooling water or a heater according to the sign of the signal. The gain of the amplifier 5 corresponds to a proportion band, and the frequency of the oscillator 7 corresponds to control cycles, so that both the parameters are varied independently of each other.

Abstract: PURPOSE:To enhance the acid resistance of a membrane by a method wherein a furan resin is uniformed being deposited on the inside and outside surfaces of a separating membrane including a PVA-based polymer as a base and also on the inside surfaces of pores of the membrane. CONSTITUTION:The separating membrane in which the base consists of a PVA polymer having a microstructure with an average pore diameter of 0.01-1mu is impregnated with a solution of a furfuryl alcohol monomer or a monomeric mixture of furfuryl alcohol and furfural, and the solution thus impregnated is hardened so that the furan resin is uniformly deposited on the inside and outside surfaces of the membrane and the inside surfaces of the pores of the membrane, in an amount of 5-90wt% of the base. The hardening of the furan resin is effected by heating in the presence of sulfuric acid, nitric acid, phosphoric acid, Lewis acid or the like as a condensation catalyst. The monomer is used by dissolving it in a solvent prepared by mixing water-soluble polymers such as polyethylene glycol. The membrane has its acid resistance enhanced without sacrificing permeability performance and is excellent in strength and Young's modulus.
