Title: Production of polyester
Inventor: NISHINO YASUHIRO
IPC: C08G63/78
Filed: 1988-12-29
Abstract: PURPOSE:To suppress agglomeration of an additive, etc., formation of insoluble particles and obtain a polyester with hardly any contamination of foreign materials or internal defects by mixing and dispersing the additive, etc., in a raw material for producing the polyester in a continuous hermetically sealed stirred device in a stage to the completion of initial polycondensation reaction. CONSTITUTION:(B) An additive (e.g. alkali metal compound) or (C) inert particles (e.g. silicon oxide) or both are added to (A) an ester (e.g. an ester having >=80mol% recurring units consisting of ethylene terephthalate) prepared by polymerizing an aromatic dicarboxylic acid and glycol, mixed and dispersed therein in a stage to the completion of initial polycondensation reaction in a continuous hermetically sealed stirred device. Since deposition of insoluble particles in the polymer can be suppressed or prevented, defects, such as fish eye, or deficiencies in magnetic recording signals in uses thereof as magnetic tapes hardly occur in films formed therefrom.

IPC: H04N19/85
Filed: 1992-12-15
Abstract: PURPOSE:To easily know why a user can not reproduce a picture by generating encoded data by predictively encoding picture data and outputting predictive- structure class information as well as the encoded data. CONSTITUTION:A predictive-structure class signal discriminating device 54 detects a predictive-structure class signal to be superimposed on the header of a bit stream to be inputted through a terminal 40, discriminating whether or not picture data can be reproduced from the inputted bit stream based on the signal. In short, it discriminates whether or not a picture decoding device can decode the predictive-structure more than the predictive-structure class of the bit stream, outputting the discrimination result as a signal S30. Further, a light emitting diode 56 is lit by the signal S30, notifying the user of it. As the result, the user can easily know why the picture can not be reproduced and the convenience can be improved.

Abstract: PROBLEM TO BE SOLVED: To detect BFG with high accuracy by making the current application width of the current flowing in the specified stator winding smaller than that of the current flowing in the stator winding other than the specified stator winding. SOLUTION: A revolution detecting means 1 receives the input of the counter electromotive force e1, e2, and e3 induced in the stator windings of three phases.

Moreover the revolution detecting means 1 detects the zero cross points of the counter electromotive force e1, e2 and e3 of three phases and converts it into a pulse n. This pulse n shows the zero cross point of the counter electromotive force e1, e2, and e3 of three phases, and is inputted into the logical pulse generating means 2 of a position signal generating means 10 and an inclination wave generating means 3. Accordingly, highly accurate BFG can be made detected, so highly accurate control can be performed.
