Patent number: 11472712Abstract: Provided is a metal oxide production apparatus that implements a flux evaporation method. The production apparatus includes a firing furnace configured to subject a metal compound to firing in the presence of flux, a cooling pipe connected to the firing furnace and configured to convert vaporized flux resulting from the firing into powder, and a recovery means configured to recover powdered flux converted in the cooling pipe. Furthermore, provided is a metal oxide production method comprising a step (1) of subjecting a metal compound to firing in the presence of flux and obtaining a metal oxide and vaporized flux, a step (2) of converting the vaporized flux into powder by cooling the vaporized flux, and a step (3) of recovering powdered flux resulting from the converting.Type: GrantFiled: June 13, 2017Date of Patent: October 18, 2022Assignee: DIC CorporationInventors: Kiyoo Kamei, Jian-Jun Yuan, Hitoshi Sekine, Hiroshi Kinoshita

Patent number: 9073018Abstract: Disclosed is a micro mixer which includes a mixing plate (14) with a first channel-forming section and a second channel-forming section. The first channel-forming section has a first channel formed for a first fluid to flow therethrough, while the second channel-forming section has a second channel formed for a second fluid to flow therethrough. Between the first channel-forming section and the second channel-forming section, there is provided a combined channel in which the first fluid and the second fluid merge with each other. The outlet of the first channel and the outlet of the second channel are opposed to each other with the combined channel disposed therebetween. The position of the outlet of the first channel facing the center axis of the combined channel is included in or the same as the position of the outlet of the second channel facing the center axis.Type: GrantFiled: June 23, 2011Date of Patent: July 7, 2015Assignee: DIC CORPORATIONInventors: Fumihiko Ishiyama, Takeshi Hizawa, Kiyoo Kamei
