Title: Cooling of optical fiber
Inventor: IINO AKIRA
IPC: C03B37/12
Filed: 1983-09-16
Abstract: PURPOSE:To carry out the quenching of an optical fiber obtained by the thermal elongation and spinning of a preform rod, and to keep the spun optical fiber in a stable state free from meandering and fluctuation, by quenching the fiber with a gyrating cooling medium. CONSTITUTION:The preform rod 7 is inserted slowly into the spinning furnace 1, and the lower end of the heated and softened rod 7 is drawn at a high speed to produce an optical fiber 8, which is quenched with a quenching means 2. A gyrating flow of a cooling medium is applied to the outer circumference of the optical fiber 8 passing through the cylinder 4 of the quenching means 2 by the following manner. When a cooling medium is introduced into the cylinder 4 through the plural injection nozzles 51-54 opened at the outer circumference of the cylinder 4 at the part 4a having large diameter, the cooling medium descends under gyration along the inner surface of the part 4a having large diameter to form a gyrating flow S. The flow is accelerated at the tapered part 4b, and further accelerated with the rotating blades 6 at the part 4c having small diameter. The optical fiber 8 passing through the cylinder 4 maintained to the above state is quenched, aligned at the center of the gyrating flow, and held at a definite position.

Furthermore, a field of several thousand degrees of temperature and 100 to 1,000 atm. pressure is locally formed. The gas in the liquid when exposed to the field, generates light and this light can be used for illumination. Also, the liquid moves in the moving direction of the supersonic wave and, therefore, causes the motion of dusts or the like included in the liquid, acting for the removal thereof. Furthermore, the attenuation of the supersonic wave in the liquid is extremely small and even a far-away object can be illuminated. Accord ing to the aforesaid system, a wide range can be clearly illuminated in the liquid.

Title: Method for gas sealing for paint film drier
Inventor: MIURA MITSUGI
IPC: B05D3/02
Filed: 1980-12-05
Abstract: PURPOSE: To surely and safely perform gas sealings, by forming gas curtains at the inlet and outlet of paint film driers, respectively, by injecting an incombustible gas at high speed.  
     CONSTITUTION: An incombustible gas is injected at high speed by gas injectors 15 above and below a paint film for the overall width of the paint film through a narrow jet 17. The incombustible gas thus injected moves at low speed through a passage 18 and the gas is absorbed by a fan 16, and the gas is again injected at high speed from the jet 17. Thus the incombustible gas is circularly used. At this time, mutual mixings between the outside air and the incombustible gas containing solvent vapor in the hollow are prevented by gas curtains formed by injecting a gas at high speed. As the injecting speed of the gas increases, the blocking effect increases. Moreover, since the returning speed of the incombustible gas to the fan 16 is low, it also maintains the blocking effect of the injected gas curtain under an excellent condition.

Abstract: PURPOSE:To dispose chips produced by cutting without flying them to surroundings by a method wherein chips produced by a cutting edge tip is sucked through the tip opening part of a cylinder body to a suction part togetherwith intake air. CONSTITUTION:Compressed air is fed from the outside to a drive part 22 of a turbine part 28 in a cylinder body 19 to rotate drive blades 30 at a high speed, and simultaneously suction blades 29 are rotated in an interlocking manner to exhaust air in a suction part 23 through an exhaust port. Thereby, a negative pressure is generated in the suction part 23, and air around the tip opening of the cylinder body 19 is sucked in the suction part 23. Thus, chips produced by a cutting edge tip 3 are sucked through the tip opening of the cylinder body 19 to the suction part 23 togetherwith intake air, and is discharged from a chip discharge part 27a. Since air in the suction part 23 is always in a suction state in which it is raised upward, the chips are pushed upward with high efficiency.
