Publication number: 20040060743Abstract: In the case of playing cards such as playing cards and the like, the switching of cards have been conventionally performed using automatic switching apparatuses in a place such as a casino where there are many participants. Many of such conventional apparatuses, however, need a technical skill in operation of the apparatuses themselves, or have a complicated structure themselves. In such conventional apparatuses, moreover, there has been no switching apparatus which is enjoyable to game participants when they see the apparatus.Type: ApplicationFiled: October 27, 2003Publication date: April 1, 2004Inventor: Masaharu Hara

Patent number: 6621533Abstract: The present invention provides a polarization separation element comprising a first array of prisms having a wedge-shaped cross-section, and a second array of prisms also having a wedge-shaped cross section. One of the prism arrays is an array of birefringent prisms. The present invention also provides a polarization conversion system having a polarization separation element of the above type for directing light having a first polarization in a first direction and for directing light having a second polarization different from the first polarization in a second direction different from the first direction; and one or more polarization conversion elements for converting light having the first and second polarizations to light having a substantially common output polarization. The polarization conversion system of the invention is suitable for use in a projection display system.Type: GrantFiled: October 11, 2001Date of Patent: September 16, 2003Assignee: Sharp Kabushiki KaishaInventors: Jason Kempton Slack, Marina Vladimirovna Khazova, Tamotsu Takatsuka, Keisuke Mitani, Kazuhiro Inoko, Graham John Woodgate, Masaharu Hara, Grant Bourhill, Emma Walton

Patent number: 5950023Abstract: A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.Type: GrantFiled: July 8, 1997Date of Patent: September 7, 1999Assignee: Nikon CorporationInventors: Masaharu Hara, Norikazu Yokonuma, Hidenori Miyamoto, Hideya Inoue, Toshio Sosa
