Research results of Professor Tsubaki and Professor Matsushita exhibited at Innovation Japan 2015

イノベーション・ジャパン2015ちらしToyo University exhibited the research results of Professor Kotaro Tsubaki at the Department of Information Sciences and Arts, Faculty of Information Sciences and Arts, and Professor Yoshio Matsushita at the Department of Architecture, Faculty of Science and Engineering, at “Innovation Japan 2015: University Trade Fair & Business Matching” held at Tokyo Big Sight on Thursday, August 27 and Friday, August 28, 2015.

“Innovation Japan” is one of Japan’s largest industry-academia matching events aimed at linking research results to industry, with the participation of over 500 universities and startups and the attendance of more than 20,000 corporate visitors every year.

In each exhibition booth, specific exhibits showing research results were displayed, and information was actively exchanged between exhibitors and attendees.

Exhibition themes

Exhibition No.K-02 «Environmental preservation & purification»: Portable fine-particle-size measuring device using a consumer digital camera

by Kotaro Tsubaki, Department of Information Sciences and Arts, Faculty of Information Sciences and Arts

椿教授ブース

This device measures particle sizes, particle-size distribution, and the number of particles using the laser diffraction method, and has the following features:

  1. It adopts the method of measuring light in front of particles, instead of measuring light beside or behind particles as in the conventional way.
  2. A consumer digital camera is used to measure the front light diffracted by the particles.
  3. To detect weaker front light than possible with an incident laser beam, the difference between images with and without particles is observed to obtain diffraction circles particular to the particles.
  4. The image recognition technology is used to measure the radius of the obtained diffraction circle and calculate the fine particle size in real time.

These features led to the simplification of the structure of the measuring device, resulting in the possibility of easy and rapid fine-particle measurement.

Exhibition No. D-03 «Disaster management»: Tougher anti-earthquake panel material using a thin stainless-steel board

by Yoshio Matsushita,Department of Architecture, Faculty of Science and Engineering

松下教授ブース

This newly developed anti-earthquake panel is an anti-earthquake reinforcement material containing stainless steel, designed to demonstrate high performance during large earthquakes. The process of installing this type of panels is: producing TPT anti-earthquake panels in a plant; transporting them to the construction site; and installing them in pillars and beams of the building to increase its seismic resistance.

Stainless steel enhances the toughness of the building structure, and the production of panels in a plant helps save on-site labor, resulting in a shorter construction period and more accurate construction work.

Additionally, because the panels can be installed while maintaining a wide-open space, they can be used in the interior frames of a building, instead of exterior frames, enabling the reinforcement work to retain openings for lighting and evacuation and avoiding detracting from the building’s appearance.。
