摘要： A molding die 1 is constituted by an upper die 1a and a lower die 1b which are made of a material transparent to an ultraviolet light, and has a cavity 3 constituted by grooves 2c, 2d, whereas a resin injection gate 4 and a resin exit gate 7 are provided so as to communicate with the cavity 3. A junction of an optical fiber 10 is inserted into the cavity 3. A UV-curable resin is injected into the cavity 3 surrounding an exposing portion of the glass optical fiber 11 from the resin injection gate 4 positioned at one of coating ends of the optical fiber 10, whereas a part thereof is discharged from the resin exit gate 7 positioned at the other coating end. The ultraviolet light is emitted through the lower die 1b so as to cure the resin, thereby forming a reinforcement resin coating. As a consequence, bubbles can be prevented from occurring due to the residual air within the reinforcement resin coating in the junction of the optical fiber 10.

摘要： A coating film drying method includes a coating process for applying a waterborne coating to a work and forming a coating film on the work, so that a coated member is produced from the work, a preliminary drying process for heating the coated member and preliminarily drying the coated member until a nonvolatile content of the coating film reaches a percentage ranging from 70% to 90%, a final drying process for heating and drying the coated member until the nonvolatile content of the coating film reaches a percentage of 97% or more and a cooling process for cooling the coated member until a surface temperature of the coated member is decreased to a temperature at which the coated member is touchable by hand, whereby the preliminary drying process is carried out by repeatedly heating and cooling the coated member at a predetermined frequency to preliminarily dry the coating film.
