摘要： A device management system is provided which is used in a client/server architecture system, enabling safe sharing of a device without compromising user convenience. In a case where the device which is connected to a client is accessed from a server, in order that the device connected to the client can be used from the server by merely connecting the device to the client without performing another operation, a filter is provided on the client side, and a pseudo bus driver is provided on the server side. The filter in the client exclusively controls client operations to the device and server operations to the device. The pseudo bus driver virtually functions as a device driver between a communication unit for the client and the application in the server.

摘要： Disclosed is a secure remote access system for improving convenience of a user by utilizing a storage device including an anti-tampering device as a user authentication device in the secure remote access system for making access and execution of job while a user is making the encrypted communication to a server from an unspecified client. Usability can be improved and thereby the job executing function can be used smoothly at the internal and external sides of the working office by providing a server client system where the server can be manipulated remotely by distributing a storage device loading the authorized anti-tampering device to users, connecting the storage device to unspecified clients by users, and using the authentication information and application stored in the storage device. A remote access system having improved security and convenient during usage of client from the user can also be provided by reducing the secret information remaining in the manipulated client.

摘要： An optical fiber comprising a core region 100 doped with Cl which raises the refractive index; and a cladding region 200, provided at the outer periphery of the core region 100, having a cladding layer 201 doped with F which lowers the refractive index is formed. The cladding region 201 to become the outermost cladding layer is configured such that the doping amount of F successively decreases within an outer peripheral part 205 including the outer periphery thereof to a predetermined doping amount which is the minimum doping amount of F within the cladding layer 201. Therefore, the stress within the optical fiber is dispersed into the outer peripheral part 205 having an enhanced viscosity, whereby the stress concentration into the core is suppressed. Since the favorable tension range at the time of drawing the optical fiber becomes wider at this time, tension control is facilitated.
