Title: Innovations by Yo Tajima

Introduction

Yo Tajima is a notable inventor based in Ashiyashi, Japan. He has made significant contributions to the field of microscopy through his innovative patents. With a total of 2 patents, Tajima has focused on enhancing the functionality and efficiency of surface inspection systems.

Latest Patents

One of his latest patents is an "Automatic focus adjusting system of microscope employed in surface." This system includes a sheet setting stage, a microscope for observing a sheet surface, and a television camera for capturing images. The focus adjusting system works by irradiating the back or front of an optically transparent sheet, creating an image on the front surface. The contrast of this image varies based on the inner physical structure of the sheet. The television camera's video signals are processed by a focus evaluation circuit, which calculates the focus evaluation degree and automatically adjusts the stage accordingly.

Another significant patent is the "Surface inspection apparatus." This apparatus features a microscope and a television camera that samples signals from the video output. It compares the instantaneous voltages of a filtered signal with a reference voltage. The system counts the number of pulses from the high-level portions of the filtered signal and moves the focal point of the microscope step by step. It determines the optimal focal point based on the maximum number of pulses, ensuring accurate surface inspection.
