Patent number: 7924243Abstract: The present invention relates to an image display apparatus for forming an image with a plurality of luminescent spots to be precisely aligned in a matrix. For example, a spacer disposed between an electron source and a face plate causes luminescent spots on the face plate spaced unevenly. The luminescent spots spaced unevenly will produce a visual unevenness in luminance which deteriorates the quality of produced image. By modifying the quantity of light of luminescent spots spaced unevenly, the visual unevenness in luminance is compensated.Type: GrantFiled: April 21, 2006Date of Patent: April 12, 2011Assignee: Canon Kabushiki KaishaInventors: Izumi Kanai, Yukio Hiraki, Makiko Mori, Kohei Inamura, Masaru Tada, Toshiyuki Kanda, Tatsuro Yamazaki

Publication number: 20100308816Abstract: Provided is a highly sensitive sensor system that can improve the S/N ratio by use of an electronic circuit without complicating the sensor body or degrading temporal resolution. A broad spectrum sensor element outputs an electric signal corresponding to a detected physical quantity, the sensor driven by multiplying a carrier signal by m-sequence code. The spread spectrum signal, after phase adjustment, is used to demodulate the sensor output signal, which corresponds to the broad spread spectrum of the physical quantity. The electrical noise generated in the sensor is a broad spread spectrum and is suppressed by low-pass filtering so as to improve the S/N ratio.Type: ApplicationFiled: October 29, 2008Publication date: December 9, 2010Applicant: Tokyo Institute of TechnologyInventors: Tomoaki Ueda, Masanori Abe, Takashi Nakagawa, Masaru Tada, Tetsuya Mizumoto, Hiroshi Handa, Adarsh Sandhu, Kiyomichi Araki
