    摘要: An automatic pressure control device for detecting and automatically controlling a gas pressure within a quartz tube in an optical fiber preform fabricating apparatus by regulating the flow rate of gas fed into the quartz tube in accordance with a preset pressure value is disclosed. The automatic pressure control device includes: a main flow controller coupled to a soot box to feed the gas into the quartz tube in accordance with the preset pressure value; a sub flow controller coupled to the soot box to feed the gas into the quartz tube to maintain the preset pressure value when there is a pressure change within the soot box; and a gas pressure controller having a pressure sensor inserted into the soot box to compare a pressure value of a signal detected in real time by the pressure sensor with the preset pressure value and to control the flow rate of the gas to maintain a constant level of gas pressure within the soot box.

    摘要: A method and an apparatus for manufacturing an optical fiber preform. The method manufactures the optical fiber preform by depositing soot created through a chemical reaction on an inside wall of a reaction tube. The created soot is charged with a first predetermined charge to adhere soot, which is not deposited on the inside wall of the tube, to an electrified body charged with a second predetermined charge opposite to the first predetermined charge. The electrified body is adapted for movement to transport the unused soot to an exterior of the reaction tube. The electrified body is energized with a charge identical to the first predetermined charge of soot, thereby exhausting soot adhering to the electrified body to an exterior of the reaction tube.
