Title: Production of parent material of optical fiber
Inventor: KONYA YOSHIHARU
IPC: C03B37/014
Filed: 1988-12-20
Abstract: PURPOSE:To obtain a parent material of optical fiber having slight defect related to oxygen by hydrolyzing a gaseous silicon compound containing chlorine in flame comprising fixed ratio of oxygen to hydrogen, stacking resultant fine powder of glass on a carrier and making resultant porous glass parent material to a transparent glass. CONSTITUTION:A silicon compound such as SiCl4 is hydrolyzed in oxyhydrogen flame containing Cl2 and <=1 oxygen/hydrogen molar ratio, then generated glass fine particles are stacked on a carrier. Thus, resultant porous glass parent material is subjected to heat and dehydration treatment in a tube furnace and melted to a transparent glass to afford the aimed parent material of optical fiber. Said parent material of the optical fiber has not defect related to oxygen, thus an optical fiber suitable for long-distance transmission having excellent transmission loss and hydrogen characteristics is obtained from said parent material.

IPC: G06K9/20
Filed: 1990-11-26
Abstract: PURPOSE:To speed up the processing of the optical character reader by providing a discriminating means which decides whether character patterns written into a document are handwritten characters or type characters and reading the character patterns with low resolution when the characters are the type characters. CONSTITUTION:The signal generated by reading the document 1 by the scanning of an image sensor 31 at right angles to the moving direction of the document while the document 1 is moved is passed through an A/D converter 32 and data on the ID part 201 and read field 202 of the document are stored in a many-value memory 11 as a quadri-value signal.
