Abstract: A duplexed control system comprises: two control devices, whereof one is set to operate as a reserve system and the other is set to operate as a regular system; a tracking bus that connects the two control devices to enable these to exchange tracking signals; and a control transmission channel that transmits computational information of these two control devices; wherein: the control devices respectively have: an own-system state evaluation section that transmits the result of state evaluation of its own system as a tracking signal through the tracking bus to the other system; an other-system signal confirmation section that receives the tracking signal through the tracking bus from the control device of the other system and thus performs state confirmation; and a transmission channel changeover section that, if the tracking signal cannot be received through the tracking bus, effects transmission of the tracking signal to the other-system signal confirmation section of the other system, through the control tr

Abstract: A method of producing a gas discharge panel includes forming a surrounding unit by positioning a first panel and a second panel together with barrier ribs to partition the space between the panels into cells for light emission when charged with a plasma gas and appropriately addressed. An anti-sealing material inflow rib surrounds the barrier ribs. Sealing material is positioned outside the anti-sealing material inflow rib. The pressure inside the surrounding unit is adjusted to be lower than pressure outside the surrounding unit while applying heat to fuse the sealing material between the first panel and the second panel whereby sealing material is prevented from inflowing into the cells between the barrier ribs during production.

Abstract: Barrier ribs 18 formed on a back substrate PA2 are brought into contact with a bonding paste layer 40 having an even surface, applying a bonding agent Bd evenly to the tops of the barrier ribs. Furthermore, a gas discharge panel having a structure in which discharge mainly occurs at locations distanced from parts of the panel connected using the bonding agent Bd is realized.

Abstract: A method is provided to steadily produce a gas discharge panel, such as a PDP, in which a panel and the top of the barrier ribs are in intimate contact in entirety. First a surrounding unit for the gas discharge panel is formed, then a process for sealing the surrounding unit with a sealing material inserted between two panels at the rim is performed while pressure is adjusted so that pressure inside the surrounding unit is lower than pressure outside. With this construction, the panels constituting the surrounding unit are bonded together while they are pressurized from outside. As a result, a panel and the top of the barrier ribs on the other panel are bonded together while they are in intimate contact in entirety. To fully acquire these effects, it is preferable that the adjustment of pressure starts before the sealing material hardens.
