Title: Hajime Yamanaka: Innovator in Optical Element Technology
Introduction
Hajime Yamanaka is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of optical elements, holding a total of 2 patents. His work focuses on innovative molding methods that enhance the quality and functionality of optical components.
Latest Patents
Yamanaka's latest patents include an "Optical Element Molding Method" and a "Molding Die for Optical Element with Lens-Barrel." The optical element molding method involves heating and pressing a molding material multiple times to create an optical element with a radius of curvature smaller than that of a sphere with the same volume. This technique addresses the issue of appearance defects, such as recesses, by adjusting the size of the closed space between the molding material and the mold's transfer surface before each heating and pressing process. The molding die for the optical element integrates a lens-barrel, allowing the optical raw material to be placed within the lens-barrel and subsequently heated and pressurized between the upper and lower dies. This process results in the integral formation of the optical element within the lens-barrel.
