摘要： A method of heating a quartz glass tube with microwaves, which method comprises supplying a gas for plasma generation in the quartz glass tube, applying microwaves to the quartz glass tube so as to generate a hot plasma in the quartz glass tube and to preheat the quartz glass tube, and then discontinuing the supply of the gas for plasma generation while applying the microwaves, whereby the quartz glass tube absorbs the microwaves to heat the quartz glass tube to a sufficient temperature in a very quick and clear manner.

摘要： Each of optical fibers has a core and stress applying members disposed around the core. End portions of the optical fibers are mounted on a fusion-splicing apparatus, and aligned through the image observation from two different lateral directions of the optical fibers. Then, a distance between positions of a bright portion end and a luminance peak closest to the bright portion end is obtained on each bright portion end of a luminance distribution of the optical fiber obtained from at least one picked-up image. The optical fibers are fusion-spliced by aligning the stress applying members so that the sum of the distances is adjusted to be minimum. Alternatively, a distance between positions of the luminance peaks respectively closest to the respective bright portion ends is obtained and the optical fibers are fusion-spliced by aligning the stress applying members so that the distance is adjusted to be maximum.
