Title: Production of glass preform for optical fiber
Inventor: SAITO TATSUO
IPC: C03B8/04
Filed: 1986-02-04
Abstract: PURPOSE:To obtain the titled preform having an uniform refractive index distribution, by preheating fine glass particles bodies obtained by a vapor-phase axial deposition (VAD) method in an unreactive gas, making the density distribution uniform and carrying out addition treatment, dehydration treatment, transparentizing treatment, etc. CONSTITUTION:Fine glass particle bodies produced by a vapor-phase axial deposition (VAD) method are placed in an atmosphere of an unreactive gas, e.g. He or N2, and heat-treated at a temperature below the sintering temperature of the fine glass particle bodies to adjust the density. The resultant fine glass particle bodies are then heat-treated in an atmosphere of an additive gas, e.g. SF6, or dehydrating gas, e.g. chlorine, to carry out addition treatment or dehydration treatment. The heat-treated fine glass particle bodies are further heated at a higher temperature and transparentized to afford the aimed glass preform for optical fibers. Thereby, since the heat treatment for adjusting the density is carried out before the sintering and transparent vitrifying, disturbance of refractive index distribution caused by a nonuniform density distribution of the fine glass particle bodies can be effectively reduced.

Filed: 1989-01-31
Abstract: PURPOSE:To eliminate the need for an optical soft focus filter by using a signal obtained by multiplying a horizontal parabolic wave by a vertical one to control an existing fade circuit and therefore obtaining electrically the video signals which are shaded off in white toward the peripheral part from the center of a screen. CONSTITUTION:The output signal of an output level control circuit 109 undergoes the control of its output level via an output level control terminal 104 as shown by D, E and F of (f). The dynamic ranges of a fade circuit 110 are shown by A and B in the diagram. Thus no fade is applied to those levels exceeding the range A, and the 100% fade is applied to those levels less than the dynamic B. An intermediate area is defined between both ranges A and B. Therefore the output video signal (g) is outputted as it is in the case of D since no fade is applied. While the output video signal (i) is obtained in the case of F since the 100% fade is applied. Then the output video signal which is shaded off in white toward the peripheral part from the center of a screen is obtained in the case of E since this area is positioned between both ranges A and B.
