Title: Kazuaki Ooyachi and Substrate-Holding Innovations.

Introduction

Kazuaki Ooyachi is an inventor based in Nagoya, Japan, whose patent work focuses on substrate-holding members. His listed inventions address the design of substrate supports, including their raised contact features and ventilation structures. Ooyachi is associated with Niterra Co., Ltd.

Latest Patents

Ooyachi’s listed patents describe two substrate-holding member designs.

The first patent concerns a base body with a vent hole near its outer edge and multiple pin-shaped projections extending upward from its surface. Some projections in the outer region have a two-part structure: a first raised element and a smaller second element extending from its top. This arrangement defines a particular geometry for the substrate-contacting features.

The second patent describes a flat-plate base body with at least one vent hole opening on its upper surface and a groove connecting to the hole and opening on the lower surface. The design also includes raised features on the upper surface and a ring-shaped raised feature along its outer edge. The patent specifies that the groove’s cross-sectional area, measured perpendicular to its flow path, is at least 1.2 mm².

Ooyachi is credited with 2 patents in the information provided.

Career Highlights

Ooyachi’s listed patent work centers on substrate-holding components that combine raised surface features with ventilation paths. The two designs describe different structural approaches to supporting a substrate while incorporating openings and grooves into the base body.
