Title: Production of polyester
Inventor: KURIHARA HIDEYORI
IPC: C08G63/78
Filed: 1986-03-13
Abstract: PURPOSE:To obtain a polyester freed of coarse particles and containing uniform fine particles, by adding a slurry formed by uniformly dispersing fine CaCO3 particles in a glycol in the presence of fine MgCO3 particles to the production system of the polyester. CONSTITUTION:A glycol slyrry is produced by uniformly and finely dispersing fine calcium carbonate particles of an average-particle diameter <=5mum in a glycol (e.g., ethylene glycol) in the presence of magnesium carbonate. This slurry is added to the production system in an arbitrary stage before completion of the polycondensation in producing a polyester by the esterification and polycondensation of an aromatic dicarboxylic acid (esterifiable derivative), e.g., terephthalic acid, and a glycol. Because the obtained polyester contains a number of uniformly dispersed fine calcium carbonate particles, a film obtained by molding it can show excellent surface smoothness, etc.

Title: Predicted value adaptive block encoding method
Inventor: OTSUKA YOSHIMICHI
IPC: H04N19/189
Filed: 1991-02-27
Abstract: PURPOSE:To prevent block distortion which is caused by adaptive mixing from being generated by using the predicted value adaptive block encoding system which obtains a function value from an input signal and a prediction signal. CONSTITUTION:A prediction unit 7 predicts the level of the input signal by using a predictive encoding method and a function converter 1 obtains the function value in specific relation with the input signal by inputting the prediction signal and input signal. Then the block encoding of the signal from the function converter 1 is performed discrete cosine transformation 2, and its output is quantized by a quantizer 3 to generate a sent signal. This sent signal is led to a reverse quantizer 4 and processed inversely to the quantization and inverse discrete cosine transformation 5 is carried out to generate a signal put back in time series and a signal decoded locally by an inverse function converter 6 from the prediction signal, so that they are fed back to the prediction unit. Consequently, the block distortion due to block adaptive switching is eliminated and the hardware is simplified.

Since the vidual field 21 of the leading end of the optical fiber is expanded like a cone as shown in the figure, the vidual field 21 is expanded also into the inside of the pipe. Consequently there is no trouble even if the leading end of the optical fiber 20 is arranged on the outside of the pipe or the inside of the pipe or the angle of attachment is inclined. The other end of the optical fibers 20 is guided to the photodetecting part of the radiometer 2 arranged on the outside of the furnace. This invention makes it possible to measure the temperature and temperature distribution of the steel pipe in the furnace precisely by a simple and easy method.
