A network system with integrated security protection facilities. The system involves a transmission unit and a reception unit, which are coupled to each other via a network. In the transmission unit, a data management unit performs centralized management of source data that is stored in a plurality of storage units in a distributed manner. In response to a data transmission request from a terminal local to the transmission unit, a data collection unit collects requested data items from the data management unit. A security processor applies appropriate security protection processes to the collected data, depending on its data confidentiality level. An identification data attaching unit attaches identification data to the transmission data. This identification data informs the recipient of what sequence of security process primitives has been applied to the source data. A transmitter sends out the security-protected data over the network. In the reception unit, a receiver accepts the data sent from the transmission unit, and an identification data extracting unit extracts the identification data attached to the received data. With this identification data, an unprotection unit unprotects the received data, thereby reconstructing the original data contents.

A personal identification terminal includes a plurality of identification means or a plurality of identification levels that are selectable for use, and means for selecting one of the plural identification means or one of the identification levels in accordance with identification means/level setting information that is received from a server every time when receiving a request for identification from the server. The personal identification terminal sends used means/level information that indicates one of the identification means or one of the identification levels that was used for the real identification back to the server in a format that enables detection of an alteration thereof together with a result of the identification.

A long-life, inexpensive rotary anode for use in an X-ray tube having an X-ray generating layer formed by CVD on a graphite substrate and capable of producing high-power X-rays without the possibility of thermal cracks or delamination. When forming the X-ray generating layer of a tungsten-rhenium alloy on the graphite substrate through a rhenium intermediate layer by CVD, material gases are supplied intermittently so that the entire part or only the surface area of the X-ray generating layer will be formed of laminated structure of ultra-thin films each 0.1-5.0 microns thick. The content of rhenium in the tungsten-rhenium alloy forming the X-ray generating layer has a gradient form, i.e. increases from the interface with the rhenium intermediate layer toward the surface, so that the total amount of rhenium added can be reduced.

A slide cover apparatus for partitioning a machining head unit from a workpiece support unit comprises first and second cover assemblies. A main board and plural sub-boards of the first cover assembly are telescopically movable in a first horizontal direction, and the main board is formed with a vertically extending rectangular window. A center board and plural sub-boards of the second cover assembly which cover the rectangular window are guided by the main board for vertical movement. The main board is connected with a cross slide table of the machining head unit which is movable in the first horizontal direction, so as to be moved bodily by the cross slide table, while the center board is connected to be moved by a spindle head of the machining head unit. The spindle head on which a tool spindle is rotatably carried extending in a second horizontal direction perpendicular to the first horizontal direction is guided for vertical movement by a column, which is movable on said cross slide table in the second horizontal direction. The center board is formed with a tool-path hole which permits the tool spindle to pass therethrough, whereby the machining head unit is partitioned from the workpiece support unit except for the tool-path hole.

A fillet rolling machine having a frame, on which a work spindle with a chuck is carried for rotation about a horizontal axis. A tailstock is mounted on the frame for supporting one end of a crankshaft to be processed while the same is grasped and rotated by the chuck. A head support is movable on the top of the frame in a direction parallel to the axis of the work spindle and carries first to third support shafts in parallel relation with the axis of the work spindle. The first and second support shafts, disposed in parallel with each other, respectively carry first and second rolling heads which respectively effect rolling treatments on fillets formed at one of journals and one of crankpins adjacent thereto of the crankshaft. The third support shafts, disposed co-axially with the first support shaft, carries a third rolling head which effects a rolling treatment on a fillet formed at a front journal of the crankshaft. Each journal and crankpin gripped by the front ends of the associated rolling heads are given rolling treatments during the rotation of the work spindle. A servomotor controllable in accordance with numerical control data is drivingly connected to the head support, so that first and second rolling heads can be brought into respective alignments with any pair of a journal and a crankpin of the crankshaft.

A communication hole (55) is provided in a pickup base (51). A laser light source (61) is provided at an end of the communication hole (55). A grating (71) is provided at another end of the communication hole (55). The communication hole (55) is provided with a heat radiation path (81) which connects the inside of the communication hole (55) with the outside of the pickup base (51). Heat generated from the laser light source (61) is radiated from the heat radiation path (81).

A memory management unit manages a memory that stores a code, and sets that the memory that stores the code to be executed is valid to make a processor execute the code stores a verification key used to verify a validity of the code in a verification-key storing unit. When the code is stored in the memory and ready to be executed by the processor, the memory management unit verifies the validity of the code using the verification key stored in the verification-key storing unit and verification information assigned to the code. The memory management unit controls to set that the memory is valid when the validity is verified by the verifying unit, and not to set that the memory is valid when the validity is not verified by the verifying unit.
摘要:
A film laminating apparatus attaches films to electronic circuit boards, such as printed circuit boards and silicone boards or wafers. The film laminating apparatus conveys a plurality of boards at intervals, forms pieces of lamination film at the intervals of the boards on a base film with a processing area between boards and continuously conveys the base film into a reduced-pressure chamber having a board loading port, a film loading port, a laminating mechanism for attaching the lamination film on the base film to the boards, and a board unloading port for ejecting the laminated boards. Shutters are provided for opening and closing shutter sections provided in the board loading port and the board unloading port of the reduced-pressure chamber, and a vacuum source is provided for evacuating the reduced-pressure chamber when the reduced-pressure chamber is closed by the shutters. A shutter section is equipped with a shutter in the film loading port of the reduced-pressure chamber, and a detector is provided for detecting when a processing area in the film between boards being fed into the reduced-pressure chamber is in the shutter section of the film loading port. A control means then operates the shutter means of the film loading port, the board loading port, and the board unloading port to close the reduced-pressure chamber according to the result of detection by the detecting means, and actuates the vacuum source to evacuate the reduced-pressure chamber to a desired degree of vacuum. Then, the laminating means is actuated.
