Patent number: 10175390Abstract: An optical element is provided which reflects a reduced amount of light even under a very high intensity lighting system used for a surgical operation, a dental treatment etc., has anti-fogging performance, and is transparent and useful for face protection. The optical element has a flexible transparent substrate and a plurality of structures disposed on opposite surfaces of the substrate at a pitch equal to or less than the wavelength of visible light. The structures are formed from a cured product of a resin having a hydrophilic functional group.Type: GrantFiled: January 16, 2014Date of Patent: January 8, 2019Assignee: DEXERIALS CORPORATIONInventors: Kimitaka Nishimura, Toru Abiko, Shinichi Matsumura

Publication number: 20180305650Abstract: A culture bag includes a culture portion which has a culture space configured to contain and culture a culture fluid. The culture space is an endless circumferential circulation space in which the culture fluid can circumferentially circulate. The culture fluid can continue to circumferentially circulate in one direction in the endless culture space. This suppresses complexification of flow of the culture fluid. As a result, bubbles can be suppressed from generating without decreasing culture efficiency.Type: ApplicationFiled: November 25, 2016Publication date: October 25, 2018Inventors: Akira Higuchi, Hiroyuki Naito, Keiji Honjo, Toru Abiko, Kazuya Hayashibe, Yasuyuki Kudo, Hirokazu Odagiri
