Title: Preparation of low-oh optical fiber matrix
Inventor: IMOTO KATSUYUKI
IPC: C03B37/018
Filed: 1979-10-12
Abstract: PURPOSE:To easily provide a low-OH optical fiber matrix without reducing its productivity by a method wherein during the growing of a porous glass matrix a chlorine atmosphere treatment is performed so as to control migration of OH gp. into the porous glass matrix. CONSTITUTION:A flame-hydrolysis burner 1 is used to produce a flame 2 including fine glass particles. The flame is used to grow a porous glass matrix 3 on the target 4 which is moving in the arrow direction 5 while revolving itself in the arrow 6 direction. Under this condition, a chlorine-containing oxidizing gas is introduced in the arrow direction 8 from the inlet of the gas-jet device 7 installed around the flame 2. As shown by the arrow 8', the chlorine-containing oxidizing gas is jetted from the periphery of the flame onto the flame so that such a gas is diffused and permeated into the flame. This causes H2O and OH ions in the flame to react with the chlorine-containing oxidizing gas. In this manner, H2O and OH ions are prevented from migrating into the porous glass matrix.

IPC: H03F3/60
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide an amplifier module having small dispersion of passing phases over the necessary bands by placing a phase compensation circuit, consisting of a parallel connection circuit of a tip open line and a tip short- circuited line between a main line, where the input side signal of a phase shifter or an amplifier passes and the ground. SOLUTION: The signal inputted via an input terminal 15 is set at the desired phase value by a phase shifter 13, based on a control signal received from a phase control circuit 17 and sent to an amplifier 14 after undergoing the phase tilt control via a phase compensation circuit 3. The controlled signal is amplified up to a certain level by the amplifier 14, supplied to an element antenna via an output terminal 16, ant then radiated into space. In such a constitution, this amplifier module uses the shifter 13 to compensate the absolute phase of passing phase and also the circuit 3 to control the phase tilt. Thus, it is possible to secure the matching of passing phases over the necessary bands, even if the passing phases have the dispersion among many amplifier modules.
