Title: The Innovations of Yoshihiro Akashi
Introduction
Yoshihiro Akashi is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of materials science, particularly in the production of single crystals. With a total of 6 patents to his name, Akashi's work has advanced the methods used in crystal manufacturing.
Latest Patents
One of his latest patents is a method for manufacturing a single crystal. This innovative approach improves productivity when a single crystal is pulled while being mechanically held at a knob section formed at the upper end of the crystal. By controlling the crucible rotational speed, a reproducible knob section with a complex shape can be formed more efficiently than if the knob section were formed by controlling the temperature of the heater. Another significant patent is an apparatus for producing single crystals. This process and apparatus enhance the production of silicon single crystals with excellent dielectric strength of gate oxide films. It achieves this by adjusting the temperature gradient of the pulled-up silicon single crystal without losing its rate of pulling. The apparatus includes a heating element outside a crucible and a pulling shaft, which allows for the effective pulling of a single crystal from the melt of the material in the crucible.
