Publication number: 20020004909Abstract: 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.Type: ApplicationFiled: June 18, 2001Publication date: January 10, 2002Inventors: Yoichiro Hirano, Yoshiyuki Kitahara, Yukiyasu Hirose, Kentato Ejima

Patent number: 6315466Abstract: 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.Type: GrantFiled: June 23, 1999Date of Patent: November 13, 2001Assignee: Olympus Optical Co., Ltd.Inventors: Naohiro Tsuchida, Yukihiko Sugita, Shinya Takahashi, Hiroshi Terada, Yoshiyuki Kitahara

Patent number: 6295420Abstract: 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.Type: GrantFiled: November 18, 1999Date of Patent: September 25, 2001Assignee: Olympus Optical Co., Ltd.Inventors: Moriya Katagiri, Yukihiko Sugita, Yoshiyuki Kitahara

Patent number: 6039476Abstract: Drive force transmission device for a camera, namely, 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. Moreover, a fork shaft and a spool shaft to be driven by film at the time of winding or rewinding the film can be driven even when the screw gear and the helical gear remain engaged with each other. This film drive mechanism occupies only a small space and is small in weight and is advantageous for the cost thereof.Type: GrantFiled: September 11, 1997Date of Patent: March 21, 2000Assignee: Olympus Optical Co., Ltd.Inventors: Moriya Katagiri, Yukihiko Sugita, Yoshiyuki Kitahara
