Abstract: PURPOSE:To enable the removal of a resin coating layer of optical fiber without carrying out the screening in a method for producing metal-coated optical fiber by performing the spinning and resin coating, then removing the resin and further coating the optical fiber with the metal. CONSTITUTION:Optical fiber 51 spun with a spinning furnace 11 is coated with a resin in a resin coating device 21 and the resin is then irradiated and cross- linked with ultraviolet rays in a resin cross-linking device 22. An ultraviolet ray shielding cylindrical unit 26 of a shutter device 25 is moved to periodically shield the ultraviolet rays and prepare optical fiber having a resin coating layer in which cross-linked parts and uncross-linked parts alternately appear. The resultant optical fiber is then dipped in an organic solvent to initially peel the resin in the uncross-linked parts and the organic solvent is subsequently penetrated into the cross-linked parts.

Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a flame detector prevented from an erroneous operation state even if noise above a fire level is produced so as to prevent a delay in fire detection. SOLUTION: When a detection element detects flame, a narrow-band filter extracts necessary frequency constituents and a smoothing means smoothens these constituents so as to output a detection signal. If the detection signal exceeds a predetermined fire determination level, generation of flame is determined and the detection signal is discharged, and the determination of the generation of flame is counted. When the count value reaches a predetermined value, the occurrence of a fire is determined, and the count value is canceled if the detection signal is below the fire level.

Abstract: PURPOSE: To provide a method of manufacturing a high-quality aggregation at a low cost by preventing the internal tissue of an aggregation from breaking down to improve its quality, and realizing a highly efficient operation and the easing of maintenance services for a manufacturing device by employing two independently separate sits of a manufacturing device instead of a single sit for the enhancement of mass-productivity. CONSTITUTION: Each lumber from thinning 2 is molded one by one in a compression- molding device 40 and is dried to reduce the moisture content of each lumber from thinning 2. Thus, its specified shape is temporarily set. In addition, the material is thermally treated by vapor under high pressure using a permanently setting device to set its specified shape permanently. The internal tissue of an aggregation is prevented from breaking down by thermal treatment under a low moisture content state. Further, it is possible to simplify the device for treating each lumber from thinning 2 because it is treated by two independently separate sits instead of a single unit as the compression-molding device 40 and the permanently setting device.  Besides it is possible to enhance the thermal efficiency significantly, reduce the operating volume and maintenance services, and utilize the existing equipment. Each lumber from thinning 2 is adhered to the other by clamping using an adhesive to obtain the aggregation.
