Publication number: 20200348578Abstract: An optical wavelength converter of one embodiment comprises: a substrate comprised of a crystalline material or an amorphous material; plural first crystal regions each having a radial first polarization-ordered structure; and plural second crystal regions each having a radial second polarization-ordered structure. In the substrate, a first and second regions are defined to be directly adjacent to each other with a virtual axis therebetween when the substrate is viewed from a reference direction orthogonal to the virtual axis. Radial centers of the first polarization-ordered structures located in the first region and radial centers of the second polarization-ordered structures located in the second region are alternately arranged along the virtual axis. The plural first crystal regions partially protrude to the second region. The plural second crystal regions partially protrude to the first region.Type: ApplicationFiled: July 16, 2020Publication date: November 5, 2020Applicant: Sumitomo Electric Industries, Ltd.Inventors: Shigehiro NAGANO, Takumi Fujiwara, Yoshihiro Takahashi, Nobuaki Terakado

Patent number: 9859596Abstract: The purpose of this invention is to provide a repeatedly chargeable and dischargeable quantum battery that is available for a long period of time without an aging change. The quantum battery is charged by causing an n-type metal oxide semiconductor to have a photo-exited structural change, thereby the electrode of quantum battery is prevented from being oxide and a price reduction and stable operation are possible. The repeatedly usable quantum battery is constituted by laminating; a first metal electrode having an oxidation preventing function, charging layer in which an energy level is formed in the band gap by causing an n-type metal oxide semiconductor covered with an insulating material to have a photo-exited structure change and electrons are trapped at the energy level; p-type metal oxide semiconductor layer; and a second metal electrode having the oxidation preventing function, the electrodes are passive metal layers formed of metals having passive characteristics.Type: GrantFiled: October 30, 2011Date of Patent: January 2, 2018Assignees: KABUSHIKI KAISHA NIHON MICRONICS, GUALA TECHNOLOGY CO., LTD.Inventors: Takuo Kudoh, Akira Nakazawa, Nobuaki Terakado

Patent number: 9799927Abstract: A repair apparatus of a sheet type cell is capable of appropriately repairing and detoxifying defects of a sheet type cell having semiconductor characteristics. The repair apparatus repairs a sheet type cell in which a storage layer is sandwiched by layers of a positive electrode and a negative electrode and at least the storage layer has semiconductor characteristics. The repair apparatus applies electrical stimulation between the positive electrode and the negative electrode, measures electrical characteristics of the sheet type cell when the electrical stimulation is applied, and specifies a value of the electrical stimulation by the electrical stimulation source while considering measured electrical characteristics.Type: GrantFiled: November 14, 2011Date of Patent: October 24, 2017Assignees: KABUSHIKI KAISHA NIHON MICRONICS, GUALA TECHNOLOGY CORPORATIONInventors: Kiyoyasu Hiwada, Harutada Dewa, Akira Nakazawa, Nobuaki Terakado
