Publication number: 20190194598Abstract: The present invention provides a method for culturing photosynthetic microalgae with which xanthophyll can be obtained more efficiently than before. The culture method of the present invention comprises a step of performing light irradiation of encysted photosynthetic microalgae containing xanthophyll in an amount of 3 to 9% by mass in terms of a dry mass. Preferably, in the step of performing light irradiation, the xanthophyll content in photosynthetic microalgae is kept at 2% by mass or more in terms of a dry mass. Preferably, the step of performing light irradiation includes step (A) of increasing the number of cells in which light irradiation (a) is performed; and step (B) of increasing the xanthophyll content in photosynthetic microalgae in which light irradiation (b) of the photosynthetic microalgae subjected to the step (A) of increasing the number of cells is performed.Type: ApplicationFiled: August 17, 2017Publication date: June 27, 2019Applicant: SHOWA DENKO K.K.Inventors: Yoko MATSUMOTO, Masaharu ISHIKURA, Hiroshi SUZUKI

Patent number: 7054668Abstract: A makeup mirror apparatus comprises a case body, a case lid, and a rotary shaft rotatably connecting the case body and the case lid. The case body is provided with a cosmetic-material containing area, a brush containing area, and operation buttons. The case lid is provided with a mirror unit, a camera portion, and a memory slot. The mirror unit is constituted such that an LCD panel is stacked on a half mirror. By manipulating the operation button, a sample image is read from a memory card loaded in the memory slot. The read sample image is displayed on the LCD panel and is overlapped with a user's face reflected in the half mirror. Makeup is performed by tracing the sample image.Type: GrantFiled: September 5, 2002Date of Patent: May 30, 2006Assignee: FUji Photo Film Co., Ltd.Inventors: Hiroshi Endo, Yoko Matsumoto

Patent number: 5391695Abstract: A process for producing a binder resin is disclosed, which comprises blending in a reactor a raw monomer for a first polymerization system and a raw monomer for a second polymerization system which undergoes polymerization through a reaction path different from a reaction path of said first polymerization system and then conducting said first and second polymerization reactions in the same reactor. A toner and a developer composition employing the binder resin are also disclosed. The binder resin can easily be pulverized and can give toners and developer compositions which hold a good charge and from which an environmentally stable fixed image can be obtained.Type: GrantFiled: November 10, 1993Date of Patent: February 21, 1995Assignee: Kao CorporationInventors: Kuniyasu Kawabe, Yoko Matsumoto
