Title: Innovations of Yoshimasa Shimura
Introduction
Yoshimasa Shimura is a notable inventor based in Katsuta, Japan. He has made significant contributions to the field of technology, particularly in the development of advanced apparatuses for scientific applications. With a total of 2 patents, his work reflects a commitment to innovation and precision.
Latest Patents
One of his latest patents is a charged particle beam apparatus. This apparatus focuses a beam of charged particles emitted from a source onto a target in a predetermined size and shape through multiple aperture members. Each aperture member is paired with a deflecting unit that enables a two-dimensional scan of the charged particle beam, responding to a supplied scan signal. The center axis of the aperture is determined based on the time-based variation in the quantity of charged particles trapped during the scan. Additionally, any deviation from a reference axis is corrected by sliding the aperture member on a plane perpendicular to the center axis.
Another significant patent is a method and apparatus for recognizing smears. This invention involves a microscope with a movable stage that positions a slide glass with blood smeared on it. The stage moves to center the view field of the microscope, allowing for sequential measurement of red blood corpuscle densities along the smear. A computer then determines the optimal test area for recognizing white blood corpuscles, facilitating an efficient scanning operation that automatically classifies the detected cells.
