Yoshio Mori

Title: Yoshio Mori: Inventor in Optical and Imaging Technologies

Introduction

Yoshio Mori is an inventor associated with Kawasaki, Japan. His work includes inventions in projection optics for semiconductor photolithography and color image pickup technology. His patent record includes 3 patents.

Latest Patents

Mori’s listed patents include “Projection Optical Apparatus and a Photographic Mask Therefor.” The invention concerns projecting patterns during semiconductor-device fabrication. Rather than using light transmitted through a mask pattern, the apparatus uses reflected light, guided from the mask to a projection optical system. The associated mask has a pattern made up of two opaque areas with different reflectances.

Another listed invention is “Color Image Pickup Device.” It uses an electrochromic element to adjust the spectral transmittance of light entering a pickup tube. A differential amplifier detects the difference between two primary color signals and applies a corresponding voltage to the element, helping the device achieve optimal white balance.

Career Highlights

Mori’s professional associations include Nippon Kogaku K.K. and Tokyo Shibaura Denki Kabushiki Kaisha. The patent descriptions reflect work spanning optical systems for semiconductor manufacturing and color imaging.

Collaborations

Mori’s listed coworkers include Kazushige Ooi and Nobuaki Yoshida.

Conclusion

Yoshio Mori’s documented inventions address practical challenges in photolithographic projection and color-image white balance, illustrating his contributions to optical and imaging technologies.
