Patent number: 7567383Abstract: An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I(?+1)/I(?) is more than 0.1 to 0.6, where I(?) is an intensity of a light reflected toward an arbitrary angle ? of 10° or less from a specular reflection direction of an incident light upon the surface at an angle of 5° to 30° from the surface normal, and I(?+1) is an intensity of a reflected light deviated from the arbitrary angle ? by 1° in a wide-angle direction. The gain of a light reflected in the direction at 20° or more from the specular reflection direction of the incident light is 0.02 or less, in which the gain is obtained by normalizing a reflected light intensity using a specular reflection intensity of a standard diffuse plate as 1. The diffuser elements have an average space therebetween of 50 to 300 micrometers.Type: GrantFiled: February 13, 2008Date of Patent: July 28, 2009Assignee: Sony CorporationInventors: Tsutomu Nagahama, Yumi Haga, Hitoshi Watanabe, Shinichi Matsumura

Patent number: 7404998Abstract: A synthetic resin card in which card warpage can be reduced and a method for producing the same are provided. By setting the difference ? in the angle of orientation between outer layers symmetrically laminated on a card core section, it is possible to reduce imbalance of stress resulting from the difference in the shrinkage factor between the outer layers, and card warpage can be suppressed. Furthermore, by setting the thickness of the outer layers at 25 ?m to 125 ?m, rising of the surface of the synthetic resin card can be reduced. By reducing the card warpage and the rising of the surface of the synthetic resin card, it is possible to improve moving characteristics when the synthetic resin card is allowed to move in a device.Type: GrantFiled: June 23, 2004Date of Patent: July 29, 2008Assignee: Sony CorporationInventors: Miki Sudo, Eiji Ohta, Shinichi Matsumura
