Abstract: Provided are an elastic cushion member and an ion exchange membrane electrolyzer using the same, which elastic cushion member can be installed even in an ion exchange membrane electrolyzer having such a small gap between an electrode and an electrode current collecting plate that a conventional elastic cushion member cannot be arranged therein. An elastic cushion member (10) has a pair of corrosion-resistant metal thin plates (11) arranged at a distance in parallel fashion and a fixing member (12) which fixes the pair of corrosion-resistant metal thin plates (11) and comprises a metal elastic body (13) wound between the pair of corrosion-resistant metal thin plates (11). The fixing member (12) is attached to the pair of corrosion-resistant metal thin plates (11) in a manner that enables detachment of the fixing member therefrom. The metal elastic body (13) is preferred to be a metal coil body.

Abstract: An ion-exchange membrane method electrolytic cell comprising a coil cushion arranged between a conductive plate and a cathode in a cathode chamber, and further an ion-exchange membrane arranged in contact with the cathode. The conductive plate is not perforated, and the coil cushion is arranged so that its axial direction is in agreement with the vertical direction of electrolytic cell. Preferably the coil cushion is made of a metal coil and has an impact resilience of 7-17 kPa. The cathode preferably has supported electrode catalyst and is made of an expanded metal with strands of 0.1-1.0 mm width and 0.1-1.0 mm thickness, and having SW of 0.5-5.0 mm and LW of 1.0-10 mm, and 48-60% open area. The electrolytic cell is energy-saving, and damage thereof can be avoided over a long period, and elevation of voltage and reduction of current efficiency with time can be minimized.

Abstract: A display device including a display layer displaying a black or white color according to an applied voltage, a transparent and non-transparent electrode that are disposed to sandwich the display layer, and a TFT driving circuit capable of applying any given voltage between the pair of electrodes. Also provided is a connection destination switching switch capable of switching the connection destination of the entire transparent electrode to an earth terminal or a connector power source terminal of an external power source connector. With this configuration, a voltage can be applied between the pair of electrodes without using the TFT driving circuit. Accordingly, if the TFT driving circuit fails to operate due to trouble caused by the displaying of information which is not permitted to be shown to others, a voltage can be applied to the display layer so that the displayed information can be erased.

Abstract: A content processing system includes a content management device storing contents and information associated with the contents, and a plurality of portable terminals capable of accessing the content management device through a network, and performs a process on the contents according to a workflow using the plurality of portable terminals. The content processing system may include a first executing unit that let at least a part of the contents and the associated information be stored in a portable terminal among the plurality of portable terminals to perform a second process when the process to be currently performed in the workflow is moved from a first process to the second process.

Abstract: An information display has an information carrier including a storable display panel separate from a processing unit including a battery, and where there is a need to perform a process such as updating or manipulating information displayed on the display panel, it is possible to perform a desired process by connecting the processing unit to the information carrier.

Abstract: Only the display device stores content files and a management device stores file management information. The content files are managed using the file management information. Because the management device does not store the actual content files, the security policy of an organization is not violated even if the management device is located outside the organization. Furthermore, because the display device stores the content files, the user desire to keep content files locally at hand is satisfied. Furthermore, because file management information consisting of small amounts of data is exchanged between the display system and the management device, the communication environment of the system does not need to be suitable to large data transmissions. Furthermore, because the management device stores the file management information, the storage capacity required by the management device is small.
