Title: Noboru Yamazaki: Innovator in Optical Fiber Technology
Introduction
Noboru Yamazaki is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of optical fiber technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
Yamazaki's latest patents include a method for producing optical fiber preform and a sintered diamond tool. The method for producing optical fiber preform focuses on preventing accidental spiking during the drawing of a preform. This involves controlling the residual helium concentration in the center part of the preform by using a transparent glass rod that is sintered but not yet doped with an alkali metal. The annealing process is conducted in an atmosphere devoid of helium gas, with specific annealing times determined by previously recorded data. His second patent, the sintered diamond tool, features a diamond sintered body that boasts superior adhesion resistance, chipping resistance, and high strength. This tool includes a base material with an inner portion containing a higher content of iron group metal and a surface portion with a lower content.
