Title: Manufacture of base material for optical fiber
Inventor: KAWACHI MASAO
IPC: G02B6/00
Filed: 1980-04-21
Abstract: PURPOSE:To manufacture a base material giving an optical fiber with superior transmission characteristics by regulating a reaction forming fine glass particles in the vicinity of the growing surface of a porous preform by the photochemical reaction of halogen molecules under ultraviolet rays. CONSTITUTION:Gaseous SiCl4 as principal starting material nd gaseous GeCl4 as starting material for a dopant for controlling refractive index are mixed and fed to torch 1 for synthesizing fine glass particles. On the other hand, the central part of growing surface 20 of porous preform 4 is irradiated with ultraviolet rays 22 emitted from light source 21 through window material 23 attached to reactor 6. SiCl4 and GeCl4 are converted into SiO2 and GeO2 with oxyhydrogen flame 2, respectively. At this time, SiO2 is formed into particles at once, yet GeO2 remaining in the vapor phase state reacts with activated chlorine, so GeO2 is inhibited from being formed into particles in the vicinity of surface 20. As a result, the dopant is deposited on surface 20 of the irradiated part at a lower deposition rate, and the refractive index distribution can be regulated independently of conditions of feeding gaseous oxygen and hydrogen.

Title: Sliding contact material
Inventor: TANI KENICHIROU
IPC: H01B1/02
Filed: 1983-03-28
Abstract: PURPOSE:To obtain a sliding contact material utilizing oxides produced during sliding as a lubricant and having improved wear resistance and low and stable contact resistance by adding specified amounts of Pd, Ag, Cu and In as essential components to Au. CONSTITUTION:This sliding contact material consists of, by weight, 65-75% Au, 3-8% Pd, 5-15% Ag, 10-18% Cu and 0.1-2% In or further contains 0.5- 10% in total of one or more among Sb, Te, Mo, Pb, Se, As and Zn and 0.01- 0.5% Fe group metal such as Ni. When the contact material is used, the amount of oxides produced during sliding is reduced, and the oxides act as a lubricant to improve the wear resistance. Since the oxides are soft and are easily removed by sliding action, the contact resistance is kept low and stable.
