Title: Takayoshi Takushima and a Safer Substrate Transfer System.
Introduction
Takayoshi Takushima is an inventor associated with Sumco Corporation in Tokyo, Japan. His patent work addresses a practical challenge in substrate handling: preventing scratches on a substrate’s mirror-like main surface during transfer.
Latest Patents
Takushima is associated with 1 patent, titled “Substrate Transfer System.” The invention describes a transfer section that moves a substrate relative to a system component, while an imaging section captures both the component’s mirror image reflected on the substrate and its real image. A judgment section analyzes these images to determine whether the clearance between the substrate and the component is abnormal. This approach is designed to help prevent contact that could damage the substrate’s polished surface.
Career Highlights
Takushima’s listed patent highlights his contribution to substrate-transfer technology and surface protection. The system uses image-based inspection to assess clearance during movement, helping identify potential contact risks.
Collaborations
Takushima is associated with Sumco Corporation. Kento Maruyama is identified as a coworker.
Conclusion
Takayoshi Takushima’s substrate transfer system applies imaging and clearance assessment to help protect delicate substrate surfaces during handling.
