  • Patent number: 7135235
    Abstract: An optical fiber preform (1) serving as a material of an optical fiber has a shoulder portion (12) thrusting beyond a middle portion (M) in a base end region (K) which is on the upper side when the optical fiber preform is suspended for a drawing process. The optical fiber preform (1) of this configuration can be easily produced by appropriately setting the heating condition, etc. for the sintering step in the production process. Thus, it is possible to omit the elongating step after the sintering step, thereby simplifying the production process. Further, in the prior-art technique, turbulence is generated in the gas flow in the furnace of the drawing apparatus toward the end of the drawing step, making it impossible to draw in a stable manner.

  • Patent number: 7081290
    Abstract: Parts, especially those formed of quartz glass, for film-forming devices, plasma-treating devices and the like have a problem of inner pollution of the devices with particles given by dropping of deposit films from the parts, a problem of hermetical sealing reduction due to bonding failure of the parts to other parts, and a problem of energy efficiency reduction due to the heat insulation failure in the parts. Parts having a thermal sprayed quartz glass film formed on a substrate have an increased ability to hold a deposit thereon, and have an increased ability to hermetically bond to other parts. The parts having a thermal sprayed black quartz glass film have an increased ability of heat insulation property. Even when washed with acid, the abilities of the parts do not lower. The parts can be used for a long period of time and their life is long.
