Abstract: An apparatus for continuously producing polyester comprises three single reactors, i.e. a single esterification reactor (first reactor), a single initial polymerization reactor (second reactor) and a single final polymerization reactor (third reactor or final polymerizer), where at least one of the first reactor and the second reactor is free from an external stirring power source, or the third reactor is a horizontal, one-shaft-type, low speed rotation type reactor. Necessary number of reactors for the esterification and polycondensation reactions can be a minimum and necessary stirring power consumption for the reaction can be a miminum, and thus polyester polymers of good quality can be efficiently produced at a minimum energy cost in a necessary minimum reactor structure.

Abstract: In a network management system in which a management application performs management operations on respective managed objects in a communication network, a template management portion stores a processing sequence described by the user into a database, and when a start request is given from a management application, a processing sequence execution portion issues a table generating request to an internal table generating portion. The internal table generating portion generates tables and then delivers an end report and the generated tables to the processing sequence execution portion, so that the processing sequence execution portion executes management operations for managed objects on the basis of the set of tables. The aforementioned processing is repeated whenever a start-up request arises from the management application. Thus, a user not only can describe behavior of management services without consciousness of a program language but also can execute management operations by describing the behavior.
