Title: Production of optical fiber
Inventor: YAMAUCHI RYOZO
IPC: C03B37/014
Filed: 1987-02-24
Abstract: PURPOSE:To contrive to reduce loss of optical fiber in heat-treating a perform having glass fine particle deposited layer on a transparent glass rod dividedly at two stages, by specifying the heat treatment temperature. CONSTITUTION:For example, SiCl4 is sent to O2/H2 burner 2, glass fine particles 4 are produced in oxyhydrogen flame 3 and deposited on a transparent glass rod 1 to form a glass fine particle deposited layer 5. A composite preform consisting of the glass rod 1 and the glass fine particle deposited layer 5 is inserted into a heating furnace 7 having a heat source 8. In the operation, the preform is heat-treated in a fluorine-containing atmosphere at a temperature >=1,000 deg.C and not to transparentize glass as the first stage. Then the perform is heat-treated in a fluorine-containing atmosphere at >=1,600 deg.C to give a transparent glass preform. By this method, optical fiber having sufficiently low loss can be readily produced.

Title: Image extending system
Inventor: NAGASHIMA TAKASHI
IPC: H03M7/46
Filed: 1986-02-28
Abstract: PURPOSE:To extend a compression data at a high speed by writing a changing point coordinate generated in a changing point coordinate generating means into a changing point coordinate buffer by a changing point coordinate write means and supplying it to a dot pattern generating means. CONSTITUTION:A compression requiring the extension is fed to a code decoding section 21. A changing point coordinate generating section 23 generates sequentially a changing point coordinate of a new line based on a code data (mode identification code and a rum length code in the horizontal mode) from a code decoding section 21 and on a changing point coordinate of a preceding line stored tentatively in a changing point coordinate buffer 22. A dot pattern generating section 24 generates an expanded dot pattern based on the changing point coordinate. Thus, a changing point coordinate generating section 23 generates a changing point coordinate of a new line without awaiting the generation of the expanded dot pattern of the preceding line by the dot pattern generation section 24 and the entire circuit speed is quickened.
