Patent number: 8298484Abstract: The present invention relates to an analyzer (1) which includes a placement part (11) for placing an analysis piece, and a photometric measurer (7) for photometric measurement of the analysis piece (2). In the analyzer (1), the placement part (11) holds the analysis piece (2) in such a way that a row of reagent pad (20) on the analysis piece (1) lie in right-and-left directions (D3, D4). The photometric measurer (7) is farther from a front than the placement part (11). The analysis piece (2) placed on the placement part (11) is conveyed from front toward rear (Direction D1), with the row of reagent pads (20) laid in right-and-left directions (D3, D4), toward the photometric measurer (7).Type: GrantFiled: May 10, 2005Date of Patent: October 30, 2012Assignee: ARKRAY, Inc.Inventors: Yasumitsu Takagi, Hisakazu Sugie, Toshiyuki Otsuki, Norimasa Nishida, Yoshikiyo Hongo

Patent number: 7884787Abstract: The invention has an object of providing a display device which can make a full use of a mirror functionality even in a dark environment. A display device comprising: image forming means (50, 60, 70, 71) for displaying information to be displayed during one state external light during the other state; input means (30) for inputting a mirror function executing instruction; and control means (82) for causing the image forming means to be switched to the other state in response to the mirror-function executing instruction. The display device further comprises an illumination unit (91) for irradiating an object to be reflected in the mirror (60) with light during the other state.Type: GrantFiled: April 27, 2005Date of Patent: February 8, 2011Assignee: TPO Hong Kong Holding LimitedInventors: Yusei Ukawa, Toshiyuki Otsuki
