Title: Innovations of Hideki Ohtsubo
Introduction
Hideki Ohtsubo is a prominent inventor based in Ube, Japan. He has made significant contributions to the field of materials science, particularly in the development of ceramic composites for light conversion. With a total of 6 patents to his name, Ohtsubo's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Ohtsubo's latest patents is focused on a ceramic composite for light conversion, which is capable of maintaining a high radiant flux even when the proportion of Gd and Ce is increased to tune the fluorescence peak wavelength to the longer wavelength side. This patent also includes a process for producing the ceramic composite and a light-emitting device that incorporates it. The ceramic composite is characterized by a solidification product that includes a specific formula, featuring a texture of continuously and three-dimensionally entangled oxide phases. These phases include a YAlO fluorescent phase activated with Ce and an AlO phase, which together account for 97% or more of the cross-section of the solidification product.
Another notable patent involves a ceramic composite material consisting of two or more crystal phases of different components. Each crystal phase has a non-regular shape and features three-dimensional continuous structures intertwined with each other. By removing at least one crystal phase, a porous ceramic material can be created, consisting of at least one crystal phase and pores, both having non-regular shapes and being three-dimensionally continuous.
