Title: Eiji Tokizaki: Innovator in Crystal Growth Technology
Introduction
Eiji Tokizaki is a notable inventor based in Ibaragi, Japan. He has made significant contributions to the field of crystal growth technology, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is titled "Pull method for growth of single crystal using density detector." This invention emphasizes that the density of a melt accurately represents its stability. The initiation of the pulling-up operation can be determined based on the changing rate of the density. The operation may commence when the density stabilizes or when the changing rate of density concerning temperature diminishes. This method ensures that the obtained single crystal is of high quality, free from minute faults or dislocations.
Another significant patent is the "Measuring device for density of liquid or high-temperature melt." This device features bobs suspended from a weight with wires. The weight can be omitted by using the upper bob for dead weight. The bobs and wires may be coated with a layer unreactive to the melt whose density is being measured. The density of the liquid is calculated from two measured values, eliminating the influence of surface tension.
