Title: Furnace for drawing optical fiber
Inventor: TAKIMOTO HIROAKI
IPC: C03B37/029
Filed: 1988-01-29
Abstract: PURPOSE:To keep an atmospheric gas flow in a furnace constant and obtain an optical fiber with hardly any fluctuation in wire diameter, by combining a discharge outlet of an inert gas in a gas diffuser and a flow passage communicating with the discharge outlet and preheating part so as to provide specific action. CONSTITUTION:A high-pressure part is formed by retention of flow in a space sandwiched between an upper sealing gas and lower sealing gas. Thereby, the upper sealing gas mainly discharges upward to seal the opening at the upper end of a diffuser 8 from the outside air. The lower sealing gas mainly discharges downward to seal an opening 14 of a shutter provided at the opening of the lower end of the furnace body from the outside air. At this time, since the lower sealing gas is heated by radiant heat from the atmosphere in the furnace or furnace core tube 3 and heat transfer from the furnace body 12, the gas flows down while minimizing the occurrence of turbulent flow without cooling an optical fiber preform 1. Furthermore, the flow rate and flow velocity of the upper sealing gas and lower sealing gas can be respectively regulated to control the respective flows and enhance sealing effects. As a result, stabilization of the atmosphere in the furnace can be simultaneously contrived.

Abstract: PURPOSE:To obtain a printing head of high efficiency without bringing about an increase in size, by a method wherein a printing wire is composed of an armature formed by a superconductive member held at its one end, a core opposed thereto, and a coil wound on the core. CONSTITUTION:A printing head 19 is composed of an armature 18 formed by a superconductive member of which with one end a prinring wire 3 is held, a plate spring 7 of which to one end the armature 18 is fixed, a core 18 opposed to the armature 18, a yoke 17 to which the other end part of the spring member 7 is fixed with a set screw 10 and the core 13 is fixed, and a coil 16 wound on the core 13. When the coil 16 is excited on a printing signal, intensive eddy current is generated on a surface of the armature 18 opposed to the core 13, and thereby the armature 18 intensively repels the core 13 to spring up the printing wire 3 against energizing of the plate spring 7. Then, when excitation of the coil 16 is turned off, the armature 18 returns to an initial position by energizing of the plate spring 7. Therefore, efficiency is improved and besides miniaturization becomes possible.
