Latest Patents

Takaaki Nacao holds a patent for a method of elongating optical fiber base material, as well as an apparatus for elongating the same. This method involves heating and softening the base material ingot in an electric furnace. The ingot is then drawn with a pair of pinch rollers, resulting in a base material rod with a smaller diameter than the ingot. The process features the formation of either a roller groove with a curvature radius larger than the outer diameter of the base material rod or a V-shaped roller groove with a cross-section consisting of straight lines on the surface of the pinch roller made of metal. The method also includes nipping with the facing roller grooves formed on the surfaces of the pinch rollers and drawing the base material rod.
