Patent number: 8648888Abstract: The present invention relates to an image display device and a method of manufacturing the image display device that make it possible to form pixels with a smaller number of sub-pixels as compared with a case where one pixel is formed so as to separately include one each of sub-pixels of three colors of R, G, and B, and make full-color display by making the sub-pixels emit light by time division. The present invention can provide an image display device that makes it possible to reduce the number of sub-pixels and form pixels at a high density by sharing respective sub-pixels between pixels and displaying the sub-pixels by time division and thus realize high picture quality and reduction in the number of parts.Type: GrantFiled: August 21, 2007Date of Patent: February 11, 2014Assignee: Sony CorporationInventors: Takehisa Natori, Yoshimitsu Tanaka

Patent number: 8167478Abstract: A kneading screw is disclosed which comprises a screw body, the screw body comprising a feed section and a kneading section, the feed section comprising screw segments for feeding a to-be-kneaded material to a downstream side and the kneading section comprising kneading segments for kneading the material. The screw body is provided within the kneading section with a multi-stage portion which gradually changes axially in rotating outside diameter. It is preferable that the multi-stage portion be constituted by kneading segments of plural kneading discs different in rotating outside diameter. With such a construction, it is possible to avoid stress concentration on an axial part of the kneading screw and thereby prevent breaking of a spline shaft and abnormal wear of kneading flights.Type: GrantFiled: November 10, 2008Date of Patent: May 1, 2012Assignee: Kobe Steel, Ltd.Inventors: Yutaka Narukawa, Yoshimitsu Tanaka
