Patent number: 5872541Abstract: A display device consisting of an electron-emitting device which is a laminate of an insulating layer and a pair of opposing electrodes formed on a planar substrate. A portion of the insulating layer is between the electrodes and a portion containing an electron emitting region in between one electrode and the substrate. Electrons are emitted from the electron emission region by a voltage to the electrodes, thereby stimulating a phosphorous to emitting light.Type: GrantFiled: June 7, 1995Date of Patent: February 16, 1999Assignee: Canon Kabushiki KaishaInventors: Seishiro Yoshioka, Ichiro Nomura, Hidetoshi Suzuki, Toshihiko Takeda, Tetsuya Kaneko, Yoshikazu Banno, Kojiro Yokono

Display device with electron-emitting device with electron-emitting region insulated form electrodes
Patent number: 5759080Abstract: A display device includes an electron-emitting device which is a laminate of an insulating layer and a pair of opposing electrodes formed on a planar substrate. A portion of the insulating layer is between the electrodes and contains fine particles of an electron emitting substance, that portion acting as an electron emitting region. Electrons are emitted from the electron emission region by applying a voltage to the electrodes, thereby stimulating a phosphorous to emit light.Type: GrantFiled: June 7, 1995Date of Patent: June 2, 1998Assignee: Canon Kabushiki KaishaInventors: Seishiro Yoshioka, Ichiro Nomura, Hidetoshi Suzuki, Toshihiko Takeda, Tetsuya Kaneko, Yoshikazu Banno, Kojiro Yokono -

Patent number: 5017988Abstract: An image reading device has an entrance window provided in a substrate for receiving the light illuminating an information bearing member bearing information to be read. A photosensor is provided on the substrate for receiving the light that has entered through the entrance window and has been reflected by the information bearing member. Further, a protective layer is formed on the photosensor opposite to the substrate, in order to maintain a constant distance between the information bearing member and the photosensor, and has a multi-layer structure of separate functions, comprising a first layer of a first function at the side of the photosensor, and a second layer of another function different from the first function.Type: GrantFiled: February 5, 1990Date of Patent: May 21, 1991Assignee: Canon Kabushiki KaishaInventors: Katsumi Komiyama, Masaki Fukaya, Kojiro Yokono, Hitoshi Toma
