  • Patent number: 6838130
    Abstract: An automotive quality paint coat (44) is laminated to the exterior surface of a molded plastic car body member or panel (118). In one embodiment, the paint coat (44) includes an exterior clear coat (45) above a color coat (46). During processing, the clear coat (45) and color coat (46) are each coated on a temporary flexible casting sheet (42) and dried. A high gloss surface is transferred to the clear coat (45) from the casting sheet (42). The paint coat (44) is then transferred from the casting sheet (42) to a thin, semi-flexible thermoformable plastic backing sheet (72) by dry paint transfer-laminating techniques. The resulting laminate (70) is thermoformed into a complex three-dimensional shape of the car body member or panel. The preformed laminate (116) is then bonded to an underlying plastic substrate material, by injection-cladding techniques, for example, to form the finished article.

  • Patent number: 6827883
    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.
