Patent number: 11056673Abstract: A covering layer (240) is formed by atomic layer deposition (ALD) and contains an insulating inorganic material. An intermediate layer (220) contains a material having a linear expansion coefficient different from that of a material of the covering layer (240). A buffer layer (230) has a surface in contact with the intermediate layer (220), that is, a first surface. The buffer layer (230) has a surface in contact with the covering layer (240), that is, a second surface. A linear expansion coefficient difference between a material of the buffer layer (230) and the inorganic material of the covering layer (240) is less than a linear expansion coefficient difference between the material of the intermediate layer (220) and the inorganic material of the covering layer (240).Type: GrantFiled: February 2, 2017Date of Patent: July 6, 2021Assignee: PIONEER CORPORATIONInventor: Jiro Fujimori

Patent number: 7965040Abstract: Each of the red, green and blue column electrodes has widened portions each having a row-direction width larger than that of the other portions. Each of the widened portions faces a head portion of each of the transparent electrodes of a pair of row electrodes constituting each row electrode pair. The widened portion of the green column electrode facing the green discharge cell provided with the green phosphor layer is located in a different position in the column direction from a position of each of the widened portions of the red and blue column electrodes respectively facing the red and blue discharge cells respectively provided with the red and blue phosphor layers.Type: GrantFiled: May 12, 2008Date of Patent: June 21, 2011Assignee: Panasonic CorporationInventors: Shingo Iwasaki, Yoshihiko Kamo, Jiro Fujimori

Patent number: 6527904Abstract: The method of producing a two-disc laminated optical video disc, includes first forming, on a first substrate, a first reflecting film capable of partially reflecting and partially transmitting a laser beam. Next on a second substrate, a second reflecting film is formed having a reflectance higher than that of the first reflecting film. A liquid ultraviolet-setting resin is applied to the first reflecting film and/or the second reflecting film. The above treated first substrate and the second substrate are bonded together, with a light-transmissible middle layer interposed therebetween. The liquid ultraviolet-setting resin is solidified by means of an ultraviolet light directed from below the first substrate.Type: GrantFiled: September 11, 1998Date of Patent: March 4, 2003Assignees: Pioneer Electronic Corporation, Pioneer Video CorporationInventors: Haruhisa Maruyama, Masayuki Uno, Hirotoshi Tabuchi, Jiro Fujimori, Masaaki Motokawa

Patent number: 5673251Abstract: This optical disk is two-substrates bonding type. In the optical disk, from the first transparent substrate side toward the second substrate side, at least following layers are laminated in that order; (1) the first transparent substrate, (2) the first optical film, (3) the intermediate layer, (4) the second optical film, and (5) the second substrate. The intermediate layer is formed of a dry photohardenable film of light transmissive type, which has a viscosity of 3,500 to 400,000 poises at a room temperature and in a non-hardened condition and has a thickness of 5 to 200 .mu.m in the non-hardened condition. The shapes of pits or grooves and the extent of light transmissive property are set so that both of the first pit-groove surface on the first transparent substrate and the second pit-groove surface on the second substrate can be read by irradiating the optical disk with the beam for reproduction from the first transparent substrate side of the optical disk.Type: GrantFiled: December 1, 1995Date of Patent: September 30, 1997Assignees: Pioneer Electronic Corporation, Pioneer Video CorporationInventors: Kenji Suzuki, Takahiro Kobayashi, Naoto Kozasa, Jiro Fujimori
