Provided is a copper alloy tube that is a drawn tube made from a CuCrZr alloy which suppresses the deterioration of mechanical strength and, in particular, the coarsening of crystal grains even in a temperature zone of a solutionizing treatment, and is thus excellent in high-temperature brazeability, as well as the manufacturing method therefor. The manufacturing method comprises a solutionizing step of heating and holding a tubular extrusion material at a solutionizing temperature of 900&#xb0; C. or greater and then water-quenching the tubular extrusion material; a main process step comprising a set of steps including a drawing process step of drawing the tubular extrusion material, and an intermediate annealing step of heating at an annealing temperature and then water-quenching the drawn material; and an adjusting process step of further drawing the drawn material and setting average crystal grain sizes in a vertical cross section along an axis as well as a horizontal cross section orthogonal to the axis to 50 &#x3bc;m or less each. The average crystal grain sizes of the vertical cross section and the horizontal cross section are each set to 100 &#x3bc;m or greater and the annealing temperature is set to 900&#xb0; C. or greater after the solutionizing step, thereby making it possible to make the average crystal grain sizes of the vertical cross section and the horizontal cross section 100 &#x3bc;m or less after the adjusting process step, even if heating is performed at at least 980&#xb0; C. for 30 minutes followed by air-cooling.

Provided is a hinge device easy to machine and manufacture. A shaft guiding recessed section and a fitting recessed section are formed on a first face of substrate of a hinge device base. As a first position adjusting mechanism, a substrate side guiding section is provided on a bottom face of the shaft guiding recessed section, and a first adjusting shaft is provided between the substrate and a first movable member. A first shaft-side guiding section of the first adjusting shaft engages with the substrate side guiding section by being accommodated in the shaft guiding recessed section, and a first shaft part of the first adjusting shaft rotatably engages with the first movable member. A fitting section is provided in the first movable member, and the fitting section is inserted into the fitting recessed section so as to be able to slide in a first direction.

One embodiment provides a printed matter managing system configured to print a file to which a label in accordance with identifying information of the file is applied and to manage the printed file as a printed matter, comprising: a detection unit configured to detect the label applied to the printed matter in one of reading the printed matter by a computer configured to limit one of using a result from the reading of the printed matter by the computer and physically carrying out the printed matter and the identifying information contained in the detected label.

Printed matter managing system

An information asset management system in a network environment includes a monitoring programthat monitors operation events performed by users and creates terminal logs, a terminal log collection programthat stores an integrated logcreated by collecting the terminal logs, and a correlation analysis programthat analyzes the whereabouts of information assets using the integrated log. When the user exports an information asset from the network environment and when the user imports the information asset into the network environment, the monitoring programmonitors these export and import events including feature values of the information assets. The correlation analysis programcompares a pre-export feature value of each information asset with a post-import feature value of each information asset to determine whether the information assets are identical and reports a list of information assets in the organization.

The policy setting support tool according to the present invention simplifies the operation required for setting up policies by providing a policy creation unitand a user interface unit. The policy creation unitcreates a draft policy from a combination of sample policies prepared for each kind of software, association information providing information on the programs that are likely to access a given object, and an access log showing a history of behavior of a given program. A user interface unitdisplays the draft policy and allows the user to check and revise it. The support tool also facilitates the maintenance of policies, by providing a differential detection unitfor detecting items for suggested change referring to the current objectand the subject information database, for presenting them to the user as through a user interface unit, and for allowing the user to revise the policy in simplified operation.

Techniques of improving the safety of an information processing system at low cost are provided, the information processing system having an OS provided with an access control function based upon discretionary access control for preventing illegal accesses to files. A method and apparatus for providing the information processing system with functions and areas usable only by a specific user different from a system administrator. The areas are provided with an access control function in order to prevent the access control function from being tampered.

Trusted computer system

A key managing system including information transmitting apparatus which transmits a date and time when secrecy protection is ended to a key controlling apparatus. The key controlling apparatus searches a key control table for an encryption key associated with a decryption key and the date and time. The key controlling apparatus transmits an encryption key from the search to the information transmitting apparatus. The key controlling apparatus discloses a decryption key for the present date and time to an information receiving apparatus in response to a request for a decryption key. The information transmitting apparatus, upon receipt of the encryption key, encrypts information using the encryption key and transmits the encrypted information to the information receiving apparatus. The information receiving apparatus, for the present date and time matching with the date and time, acquires a disclosed decryption key and decrypts the encrypted information by using the decryption key.
