  • Publication number: 20070241660
    Abstract: There is disclosed an SED formed by arranging a front substrate having a plurality of fluorescent layers and a metal back and a back substrate having a plurality of electron emitting elements and wiring lines for the elements so that the substrates face each other to join peripheral edge portions of the substrates to each other. The metal back is electrically divided into a plurality of island-like regions, and connected to a common electrode arranged around the regions. The common electrode has a plurality of electrode films separated from one another in a longitudinal direction of the common electrode and an annular resistance film. The resistance film is laminated thereon so as to electrically connect the plurality of electrode films to one another, and connected to an edge portion of the metal back.

  • Publication number: 20070228946
    Abstract: In an image display device which comprises a front plate having phosphor layers, resistance layers formed between the phosphor layers, a matal back layer which is formed on the phosphor layers and the resistance layers and segmented into regions by gaps in a first direction X perpendicular to the scanning direction for image display and by gaps on the resistance layers in a second direction Y which coincides with the scanning direction for image display, and high-voltage supplier which applies a high voltage to the matal back layer, and a back plate which is set opposite to the front plate and has a number of electron emitting elements arranged on it, characterized in that the resistance layer present between each region segmented by the gaps is discretely formed in its portions with low-resistance regions which are relatively lower in resistance than the other portions.

  • Publication number: 20020004909
    Abstract: Systems and methods for managing information and access to information in an information management system comprising an ID control center, at least one owner terminal, at least one third-party terminal, and a network linking the ID control center and the terminals. The present invention provides four types of ID management methods and systems. Service type 1 enables an ID holder to upload, store, and edit the information assigned to the ID via an ID control center. Service type 2 enables an information requester to access the information assigned to an ID with the permission of the ID holder. Service type 3 enables an ID holder to utilize the information assigned to the ID to obtain products and/or services from a third party via an ID control center. Finally, service type 4 enables an ID holder to place an order for a third party's products and/or services to be delivered to another ID holder, using the second ID holder's ID information and with the second ID holder's permission.

  • Patent number: 6315466
    Abstract: A clutch unit according to the present invention includes a driving sleeve fixed to a driving shaft and a driven sleeve fixed to a driven shaft. A coil-like clutch spring is received on the driven sleeve, and a clutch sleeve is received on the driving sleeve. When the driving shaft is rotated normally or reversely, the driving sleeve abuts one of the arm portions of the clutch spring. Consequently, the clutch spring engages the driven sleeve. Torque producing rotation in either direction is transmitted to the driven shaft. The clutch unit also can operate as an overrunning clutch. When the clutch unit is adapted to a film feeding and driving system in a camera, the clutch unit can be positioned to utilize what had been dead spaces in a camera body, thus promoting compact camera design.

  • Patent number: 6295420
    Abstract: A film drive mechanism for a camera, in which a drive force of a motor is transmitted through a differential gear mechanism to a wind shaft and a rewind shaft and is also transmitted through a screw gear to a spool shaft or a fork shaft whereby, operations of winding and rewinding film are performed. The rewind shaft is placed in such a manner as to be inclined to the drive shaft of the differential gear mechanism. Also, a pair of engaging gears in the drive force transmission device are aligned so that their axes of rotation are oblique to one another. This film drive mechanism requires small space than conventional designs and is small in weight and is advantageous for the cost thereof.
