Abstract: PROBLEM TO BE SOLVED: To reduce an effluent polymer to be reprocessed under the condition that the excessive rise of the polymer viscosity of a polymerization reaction vessel is prevented from occurring during the period ranging from the occurrence of a cutter trouble in a following process or a chipping process to its restoration in the controlling of the polymer viscosity of the polymerization reaction vessel in a polyester plant. SOLUTION: This controlling device controls with a viscometer 2 and a viscosity controlling meter 4. However, when the rotational frequency of a transferring gear pump is reduced, the calculation result of a gradient setting function generating calculating block equipped with a program holding function is inputted in the set point of a vacuum pressure controlling meter 7. Thus, the vacuum pressure controlling meter can be gradually controlled to the atmospheric pressure side, resulting in allowing the suppress an excessive polycondensation reaction.

Abstract: PURPOSE:To correct a count error without using a clock of high repetitive frequency by dividing one period T of a clock equally by (m) and delaying a rectangular wave by T/m at every time. CONSTITUTION:A delay circuit 13 consists of m/2 delay circuits which divide one period T of the clock equally by (m) and delay the rectangular wave by T/m at every time. A detecting circuit 14 detects the difference between the leading edge of the output of an FF 12 operating with the rising rectangular wave and clock and the leading edge of the output of a phase detector 1 from the output of the delay circuit 13. A detecting circuit 15, on the other hand, detects the difference between the trailing edge of the output of the FF 12 and the trailing edge of the output of the phase detector 1 from the output of the delay circuit 13. Then, the phase difference found by a phase meter is N1+(N2-N3), where N1 is the output of an output terminal, N2 is the output of the detecting circuit 14, and N3 is the output of the detecting circuit 15. Consequently, a value which can not be corrected because of <=1 count of the counter 3 can be measured with the accuracy of the delay circuit 13.
