Title: Tomoko Hada: Escalator Handrail Manufacturing Innovations.

Introduction

Tomoko Hada is an inventor based in Tokyo, Japan, whose patent work includes methods for manufacturing escalator handrails. She is associated with Mitsubishi Electric Corporation and has 3 patents.

Latest Patents

Hada’s listed patents focus on combining metallic steel wire with thermoplastic resin to produce escalator handrails.

“Method of manufacturing an escalator handrail” describes preheating a steel wire made of a center elemental wire surrounded by strands. The heated wire is integrated with molten thermoplastic resin to form a composite material, which is then cooled.

A second “Method of manufacturing escalator handrail” details producing the steel wire by arranging and tensioning its center wire and surrounding strands so that their spacing is uniform. The wire is heated to at least the temperature of the molten thermoplastic resin, integrated with the resin, and extruded through a die shaped to the handrail’s cross-section. The resulting composite is forcibly cooled.

Career Highlights

Hada’s patent contributions address manufacturing processes for composite escalator handrails, including wire preparation, heating, resin integration, extrusion, and cooling. These methods describe ways to form the handrail material and shape it during production.

Collaborations

Hada is associated with Mitsubishi Electric Corporation. Her listed coworkers include Yoshitomo Nishimura and Hidetoshi Takeyama.

Conclusion

Tomoko Hada’s listed inventions focus on manufacturing escalator handrails by integrating metallic steel wire with thermoplastic resin through controlled preparation, forming, and cooling processes.
