The carbon dioxide adsorption element 110 for adsorbing carbon dioxide in air comprises a foil-like or plate-like support member 111, a porous aluminum oxide film 112 covering the support member 111, and the amine groups 113 clinging to the inner surface of each pore 112a of the film 112 for carbon dioxide adsorption. The film 112 is formed by oxidation of aluminum or aluminum alloy. The depth direction of each pore 112a of the film is the thickness direction of the support member 111.Type: ApplicationFiled: February 25, 2005Publication date: July 26, 2007Applicants: SHIMADZU CORPORATION, KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Hidefumi Saito, Yoshihiko Takemura, Takatoshi Shoji

Patent number: 7088312Abstract: A plasma display is provided with a plasma display panel, data drivers which apply data pulse to data electrodes of the plasma display panel, a control circuit which t controls an operation of the data drivers based on a video signal, and a protection signal output circuit. The protection signal output circuit outputs a protection signal to the control circuit when sum of currents supplied from the data drivers to the data electrodes within a time equal to one sub-field or more to less than one frame exceeds a previously set first specified current value. The protection signal restrains the operation of the data drivers.Type: GrantFiled: January 25, 2002Date of Patent: August 8, 2006Assignee: Pioneer CorporationInventors: Mitsuhiro Ishizuka, Eiichi Urushibata, Tadashi Nakamura, Hiroshi Shirasawa, Takatoshi Shoji

Publication number: 20050219158Abstract: A plasma display device in which, regardless of whether the display data amount is large or small, the variances in the luminance can be suppressed, the gradation of the display data can be faithfully displayed, the display quality is excellent, the power consumption is small, and a method of driving the plasma display device. A subfield-by-subfield display load calculating part calculates display load amount allocated to the respective subfields from the display data with respect to each of the subfields. Based on the calculated data of the display load amount, a sustain frequency calculating part calculates optimum sustain frequencies for the respective subfields. A sustain frequency controller within a drive controller generates sustain pulse voltage data based on the sustain frequencies calculated with respect to each of the subfields.Type: ApplicationFiled: March 18, 2005Publication date: October 6, 2005Inventors: Takatoshi Shoji, Shinji Hirakawa, Shinya Tsuchida

Publication number: 20050156824Abstract: A driving method and a driver circuit for improving the definition of display image on a plasma display device. In an initial state in an addressing discharge period, a scanning electrode is applied with a scanning base pulse at a first power supply potential. This suppresses a weak erroneous discharge between a scanning base pulse and a display data pulse. Next, the scanning electrode is applied with a scanning pulse. After the scanning pulse has been applied, the scanning electrode is applied with the scanning base pulse at a second power supply potential. In this way, the level of the scanning base pulse applied to the scanning electrode after the end of the application of the scanning pulse in the addressing discharge period is lower than the level of the scanning base pulse applied to the scanning electrode before the application of the scanning pulse.Type: ApplicationFiled: December 2, 2004Publication date: July 21, 2005Inventors: Sohei Okamoto, Takatoshi Shoji, Hiroshi Shirasawa

Patent number: 6862007Abstract: A method for driving an alternating current (AC) plasma display panel is provided which is capable of making sustaining light emission inconspicuous caused by erroneous discharge during a period when supply power becomes stable even if erroneous discharge occurs due to an influence of residual charges produced at a time of starting operations of the AC plasma display panel. A driving method for one frame is changed between a period (supply power stability waiting period) required until the supply power becomes stable and a display period. Time required until a voltage becomes stable is for example 0.5 seconds to 1 second after power-ON. In a field during this period, one field is divided into a plurality of sub-fields and the number of repeated pulses is smaller during a sustaining period of each sub-field than that of repeated pulses during a sustaining period of a sub-field in the display period. For example, no sustaining pulse is fed to a scanning electrode.Type: GrantFiled: October 25, 2002Date of Patent: March 1, 2005Assignee: NEC Plasma Display CorporationInventors: Takatoshi Shoji, Yukinori Kashio
