Title: Production of polyester fiber with low polymerization degree
Inventor: TANI KATSUYA
IPC: D01F6/62
Filed: 1979-03-01
Abstract: PURPOSE: A polyester of low polymerization degree is subjected to a simplified  direct-spin- draw process to give pilling-resistant fibers in stable operations.  
     CONSTITUTION: A synthetic linear thermoplastic polyester of low polymerization degree is melt spun through spinnerets and cooled at once to a temperature of lower than 0°C by blowing a cooling fluid to the spun yarns under the spinnerets. Then, the yarns are heat drawn by passing through the heating zone and taken up by the first taking-up rollers at over 2500m/min, preferably 3,000W5,000m/min, to give said polyester fibers of 0.53 or lower, preferably 0.35W0.48, intrinsic viscosity (IV) measured in a mixed solvent of phenol/tetrachloroethane (6/4) at 30°C. The fibers produced by the process in the present invention have lower tensile properties than those of fibers produced by conventional processes, reflecting the feature in microstructure, and show high pilling resistance. Therefore, high pilling-resistant fibers can be obtained without large reduction in polymerization degree.

Title: Printer focusing method
Inventor: OZAWA YOSHIO
IPC: G03B27/46
Filed: 1988-02-05
Abstract: PURPOSE:To attach importance to a focus and to correct an AF curve in a short time by correcting the AF curve from a lens position and an actual magnification; said lens position is selected when photo-printing in pitch responding to minimum resolution is performed. CONSTITUTION:If a specified pitch is different from a pitch responding to the applied minimum resolution of a lens, the specified pitch is subdivided and heightened in accuracy, and the photo-printing process is performed. Suitable lens position with a high accuracy can be selected by repeating said operation and by subdividing the specified pitch in order. Then, when the most suitable lens position is selected when the photo-printing process is performed, the AF curve is corrected by the lens position and by the actual magnification. Accordingly, the most suitable lens position and conjugate length are obtained even if any other magnification is selected. Thus, converging time for obtaining the lens position for the most suitable focus is reduced, since the focusing is performed with the magnification fixed.
