Latest Patents

Aoki’s patent for an X-ray source and fluorescent X-ray analyzing apparatus describes a layered target design. An electron beam strikes a primary target, producing continuous X-rays that excite a superimposed secondary target. The secondary target then emits characteristic X-rays, and the arrangement is designed to improve the efficiency of their generation for fluorescent X-ray analysis.

Another patent for an X-ray source describes an electron-optical system operated at a positive potential while the transmission target remains at ground potential. The electron beam is focused at higher energy as it passes through the optical system, then decelerated just before reaching the target. This approach reduces the effects of spatial charge and chromatic aberration, helping to achieve a smaller focus size.

Career Highlights

Aoki’s listed organizational affiliations include Toshiba Electron Tubes & Devices Co., Ltd. and The University of Tokyo. His patent work reflects an emphasis on X-ray source design and the control of electron beams.
