    摘要： A treatment method for an optical fiber including accommodating an optical fiber inside a treatment chamber; introducing a deuterium containing gas into the treatment chamber; and in a deuterium treatment step, exposing the optical fiber to atmosphere of the deuterium containing gas. In the deuterium treatment step, a deuterium concentration D in the treatment chamber during the deuterium treatment is calculated from an initial value A of a deuterium concentration in the deuterium containing gas inside the treatment chamber, a concentration B of oxygen in an ambient atmosphere of the treatment chamber, and a concentration C of oxygen in the deuterium containing gas inside the treatment chamber, and the deuterium concentration in the treatment chamber is controlled based on the deuterium concentration D calculated. Other gases such as hydrogen containing gas or nitrogen containing gas may also be used according to the invention.

    摘要： An optical fiber coating die is made such that an interfacial shear rate of the optical fiber to the resin coat is calculated in accordance with a pressure value of resin inside a coating cup, and the interfacial shear rate is in a range of −1.5×105 to 0 sec−1. Also, an optical fiber drawing die is made such that the interfacial shear rate of the optical fiber to the resin coat is calculated in accordance with a diameter of a coating resin, and the interfacial shear rate is in a range of range of −3×105 to 2×105 sec−1. By doing this, an optical fiber drawing die which can be used in an optical fiber drawing method so as to realize stable resin coating operation even in high-speed drawing operation and high productivity can be realized.

    摘要： A solar cell includes a graphite substrate, an amorphous carbon layer having a thickness of not less than 20 nm and not more than 60 nm formed on the graphite substrate, an AlN layer formed on the amorphous carbon layer, a n-type nitride semiconductor layer formed on the AlN layer; a light-absorption layer including a nitride semiconductor layer formed on the n-type nitride semiconductor layer; a p-type nitride semiconductor layer formed on the light-absorption layer; a p-side electrode electrically connected to the p-type nitride semiconductor layer; and an n-side electrode electrically connected to the n-type nitride semiconductor layer. The amorphous carbon layer is obtained by oxidizing the surface of the graphite substrate.
