    摘要： In an optical fiber coating method comprising the steps of; applying an injecting first coating resin to the outer periphery of the optical fiber while inserting the optical fiber through a first die hole provided in a first coating die; and applying an injected second coating resin onto the first coating resin while inserting the optical fiber through a second die hole provided in a second coating die. Wherein a disk-shaped upper end face of the second coating die and a basically disk-shaped lower end face of the first coating die having a protrusion formed around the first die hole and projecting in the passing direction of the optical fiber are opposed to each other so as to arrange the first and second die holes concentrically, and the second coating resin is injected into the second die hole by way of a gap formed between the lower end face of the first coating die and the upper end face of the second coating die, so as to reduce an annular lower-pressure region formed around the optical fiber in a flow of the second coating resin within the gap.

    摘要： In an optical fiber coupler making apparatus which makes an optical fiber coupler by thermally fusing a plurality of optical fibers together by use of a heater and then elongating thus thermally fused part, the heater comprises a heating element which is made of zirconia and which has a slit for containing the optical fibers. The inner face of the heating element is preferentially heated due to a characteristic of its material. Consequently, if optical fibers are contained in the fiber receiving slit, then they can be thermally fused at a sufficiently high temperature in a short period of time, whereby reducing mingling of impurities into the optical fiber coupler. Therefore, the heating element made of zirconia is effective as means for preventing impurities from mingling from the outside thereof. Also, performances of the heating element can be maintained over a long period of time even if the optical fibers are thermally fused at a high temperature. Further, the evaporation of impurities, which may adversely affect characteristics of the optical fiber coupler, hardly occurs from the heating element.

    摘要翻译： 在通过使用加热器将多根光纤热熔合在一起并随后拉伸这样的热熔融部分而制造光纤耦合器的光纤耦合器制造装置中，加热器包括由氧化锆制成的加热元件， 用于容纳光纤的狭缝。 由于其材料的特性，加热元件的内表面被优先加热。 因此，如果在光纤接收狭缝中包含光纤，则可以在短时间内以足够高的温度热熔融，从而减少杂质混入光纤耦合器中。 因此，由氧化锆制成的加热元件作为防止杂质从其外部混合的手段是有效的。 此外，即使光纤在高温下热熔融，也可以长时间保持加热元件的性能。 此外，可能不利地影响光纤耦合器的特性的杂质的蒸发几乎不会从加热元件发生。
