摘要:
An electric double layer capacitor has a pair of polarized electrodes in the form of electrode bodies each comprising a porous sintered body, and a pair of current collectors for collecting electric charges stored in the polarized electrodes, the current collectors being in the form of electrically conductive films. The electrically conductive films have surfaces dissolved by a solvent and joined to the electrode bodies with dissolved portions of the electrically conductive films being present in pores of the electrode bodies. The polarized electrodes and the current collectors are held in stable contact with each other, with a reduced contact resistance therebetween. The electric double layer capacitor thus has a small internal resistance.

A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.

摘要:
A management device of a license management system acquires a usage request of a content from an SD card or a printer via a relay device, analyzes the acquired usage request, acquires usage environment information of the SD card or the printer from the relay device, analyzes the acquired usage environment information, generates license information including a usage rule corresponding to the analysis results of the usage request and the usage environment information, generates instruction information indicating how to handle the license information in the relay device based on the analysis result of the usage environment information, embeds the generated instruction information in the license information, and sends the license information to the relay device. The relay device receives the license information in which the instruction information is embedded, and transfers the received license information to the SD card or the printer according to the instruction information which is embedded in the license information with performing certain processing or without performing any processing to the license information.

摘要:
An explosion-proof battery includes a cover unit fit into an open portion of a cylindrical cup-like casing. The cover unit is electrically connected to a lead tab extended from an electricity generating unit installed in the casing. The cover unit includes a metal terminal plate of relatively high rigidity, a pressure sensitive plate in the form of a metal plate having relatively high flexibility and vulnerability, a fixing plate of insulating material, an electrical conductive member including an upwardly projecting portion and a base portion, and a ring-shaped gasket of insulating material. The terminal plate and the fixing plate have respective vent holes. The electrical conductive member and the pressure sensitive plate are connected to each other at a connecting portion on the projecting portion of the conductive member by welding. A tip end portion of the lead tab is connected to the base portion of the conductive member. When the pressure sensitive plate expands outwardly due to an extreme increase of the inner pressure, the conductive member is pulled upwardly with the pressure sensitive plate in the vicinity of the connecting portion thereof and is broken to cut off the current path between the lead tab and the terminal plate.
摘要:
A content usage device includes (i) a license management unit that holds license information and (ii) a content output unit that uses a content in compliance with license information and outputs the content in at least one manner of a sound, video and data. The license management unit, upon receiving a request of license information from the content output unit, requests a license management unit of another content usage device to transfer the license information and acquires the license information, and passes the acquired license information to the content output unit. The content output unit uses a content in compliance with the license information passed from the license management unit.
摘要:
A mail gateway generates an identifier for each attached file included in the e-mail addressed to a user and held in a mail server, and notifies a mail terminal belonging to the user of a list of generated IDs. When the user selects attached files that the user wants to attach to the e-mail from the list of IDs that is notified from the mail gateway, the mail gateway constructs e-mail including the selected attached files and the mail server transmits the constructed e-mail to addresses of the receivers of the e-mail.
