  • Preform and process for the production thereof
    Patent number: 6231243
    Abstract: A preform used for producing an optical fiber fixing member having an optical fiber fixing part and a lower-staged part by a mold shaping method, is formed so as to be composed of a large-thickness portion having an upper surface or a peak portion to which that transfer-shaping surface of transfer-shaping surfaces of a shaping mold which is to shape the said optical fiber fitting portion(s) comes into contact at an initial stage of mold shaping, and a small-thickness portion having an upper surface or a peak portion to which that transfer-shaping surface of transfer-shaping surfaces of the shaping mold which is to shape the upper surface of the lower-staged part comes into contact at an initial stage of the mold shaping, the preform being formed in a configuration in which the said small-thickness portion is adjacent to the large-thickness portion, the form of the preform viewed as a plan view parallels with the form of the said optical fiber fixing member viewed as a plan view and the form of the preform vie
