Presicion polishing technology of Diamond wafers

Group of Osaka univ, AIST and TDC are now developing precision polishing technology of Single/Poly crystalline diamond wafers under the support of JST. The article of our research was published in Scientific reports. Diamond is the hardest known substance and essentially does not react with chemicals. Polishing it with a similarly hard tool damages the surface and conventional polishing chemistry is slow. The significant feature of our newly developing technology is efficient(high speed) and damage free (low stress and less scratch marks) . Scientific reports:https://www.nature.com/articles/s41598-020-76430-6 Release from Osaka univ:https://resou.osaka-u.ac.jp/en/research/2020/20201110_3

TDC received “excellent prize” by The Japan society for precision engineering

TDC is awarded by the Japan society for precision engineering. It is 4th “Monodukuri award” and we got “excellent prize”. The reason of award is “development of super fine polishing process for Rolls”. It is a great honor to receive this award. http://www.jspe.or.jp/activity/awards/ For more detailed info about “Roll polishing technology”, please check TDC’s website. https://mirror-polish.com/en/precise-mirror-polish-surface-on-roll-and-shaft/ Precise Mirror Polish Surface on Roll and Shaft

balloon project

I found beautiful movie of electric blue clouds. It is known as noctilucent clouds. It is a kind of weather phenomenon that the clouds shine reflecting sunlight from below the horizon. It happens before sunrise or after sundown. This movie is captured by NASA’s balloon project. A very small part which is made by TDC is used for position control of the camera on the floating balloon. I’m very happy to know that our technology is contributing in such spectacular project. I want to share this beautiful and wonderful movie. https://www.nasa.gov/feature/goddard/2018/nasa-balloon-mission-captures-electric-blue-clouds

Tribology fusion research consortium “International symposium”

International symposium organized by Tribology fusion research consortium will be held at Sendai International conference center on 20-21 Feb. http://tribology.niche.tohoku.ac.jp/sympo2019/ This symposium will deal with broad topics in fusion research for a sustainable society. Keynote speakers are internationally recognized scientists who have been involved in various industry-academic collaborations, and creation of new technologies and venture companies. In the poster session, Tri-F member companies and others will display their successful collaboration with university and their core technologies. This session will provide participants with opportunities to find links for future collaborators and businesses.

TDC’s polishing technology for Modern Art

TDC has collaborated with Yuta Hayakawa creating modern art. This activity has been featured on newspaper Nikkan kogyo Shimbun. TDC developed only-one technology of polishing thin foil in long length. This technology has been used for mold for graphene growth process, hydrogen filter, substrate for flexible devices and so on. I have never anticipated the usage of art work until this time. I feel it is a kind of serendipity.   We polished stainless foil shiny, but it seems like transparent by effect of angle and magic of the artist.
