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

Patent number: 7842142Abstract: High-strength parts and a method for producing them can be provided, where such parts exhibit hydrogen embrittlement resistance and strength after high-temperature forming. For example, the atmosphere in a heating furnace can contain less than about 10% hydrogen and/or have a dew point of about 30° C. or less. The amount of hydrogen penetrating a steel sheet during heating can thereby be reduced. After forming, quench hardening in a die assembly and post-working can be performed. Post-working can include shearing followed by re-shearing or compression forming; punching with a cutting blade having a continuously reduced base width; punching with a tool having a curved blade and a protrusion at the tip of the cutting blade, where the curved blade may include a shoulder portion of given radius and/or angle; fusion cutting; etc. Tensile residual stresses after punching can be reduced and resistance to hydrogen embrittlement can be improved.Type: GrantFiled: September 15, 2005Date of Patent: November 30, 2010Assignee: Nippon Steel CorporationInventors: Kazuhisa Kusumi, Hironori Sato, Masayuki Abe, Nobuhiro Fujita, Noriyuki Suzuki, Kunio Hayashi, Shinya Nakajima, Jun Maki, Masahiro Oogami, Toshiyuki Kanda, Manabu Takahashi, Yuzo Takahashi

Patent number: 6326981Abstract: A color display apparatus, such as a color liquid crystal display apparatus, is composed of a multiplicity of sub-pixels each designed for displaying one of a plurality (k) of mutually different mono-colors and arranged in rows and columns so as to form pixels each with a plurality of mutually adjacent sub-pixels. The sub-pixels and pixels are so arranged that a number n given by dividing a total number of sub-pixels arranged in a row or column with a total number of pixels arranged in the row or column is set to satisfy: 1<n<k, wherein k denotes the plurality of the mono-colors displayed by the sub-pixels. As a result, the pixel pitch can be reduced to provide an increased display density and an improved display quality.Type: GrantFiled: August 28, 1998Date of Patent: December 4, 2001Assignee: Canon Kabushiki KaishaInventors: Hideo Mori, Eisaku Tatsumi, Kazuhiro Matsubayashi, Masanori Takahashi, Toshiyuki Kanda

Patent number: 5816677Abstract: A backlight device suitable for illuminating a transmission-type display device, such as a liquid crystal device, is constituted by a reflection member for reflecting light, a transmission member disposed opposite to the reflection member so as to form a space from the reflection member, and a light source disposed to emit light into the space. Light issued from the light source into the space is reflected by the reflection member and transmitted through the transmission member. The transmission member is preferably provided with a reflection layer having apertures having an aperture ratio which increases with an increase in distance from the light source toward a center of the space in a linear function, a hyperbolic function or a function intermediate therebetween of the distance from the light source. Between the transmission member and the display device, a prism sheet and/or a diffusion sheet may be disposed so as to improve the frontal illumination performance.Type: GrantFiled: May 22, 1995Date of Patent: October 6, 1998Assignee: Canon Kabushiki KaishaInventors: Katsumi Kurematsu, Yoshihiro Onitsuka, Toshiyuki Kanda

Patent number: 5808597Abstract: An illumination device for a liquid crystal display apparatus to be disposed on a back side of a liquid crystal display panel is constituted by a plurality of illumination circuits, and plural hot cathode tubes including at least one hot cathode tube associated with each illumination circuit. Each illumination circuit includes a life detection circuit for detecting an end of life of a hot cathode tube, and a turn-off circuit for turning off the hot cathode tube depending on an output of the life detection circuit. Each illumination circuit controls said at least one hot cathode tube associated therewith independently from the other hot cathode tubes. As a result, even when a hot cathode tube approaches its end of life, the illumination device can be partially turned off to allow an operator to continue the operation on the liquid crystal display apparatus.Type: GrantFiled: March 4, 1996Date of Patent: September 15, 1998Assignee: Canon Kabushiki KaishaInventors: Yoshihiro Onitsuka, Hiroshi Takabayashi, Toshiyuki Kanda

Patent number: 5796450Abstract: An illumination device includes a plurality of linear light sources disposed with a prescribed spacing therebetween, a light guide means disposed between or among the linear light sources, and a reflection means disposed behind the light guide means so that light issued from the linear light sources is transmitted through the light guide means and reflected by the reflection means to be emitted in a direction forward from the light guide means. Further, a luminance distribution-adjusting means for reflecting light transmitted through the light guide means is disposed along the light guide means in a disribuption density which varies continuously at a changing rate free from discontinuity so as to adjust the luminance distribution of the light emitted in the direction forward from the light guide means. The illumination device may be suitably used as a backlight behind a liquid crystal panel to provide a liquid crystal display apparatus having improved display qualities.Type: GrantFiled: December 13, 1995Date of Patent: August 18, 1998Assignee: Canon Kabushiki KaishaInventors: Toshiyuki Kanda, Hiroshi Takabayashi, Yoshihiro Onitsuka
