摘要:
The control unit of a computer system comprises a first storing device for holding written data while the power is on, a second storing device for holding the written data, even when the power is off and a power-off preserving device for terminating power to the system after transferring the data held in the first storing device to the second storing device. The control system can be utilized to only store the effective contents of the operating data to thereby enable data reconstruction upon resumption of power. The control device can interface with a window system processing device which can enable the refreshing of graphic display information upon resumption of power. The second storing device may have limited memory capacity and the operator can be informed of its capacity prior to a final shut-off of power. The control unit can further identify those programs that are not capable of being restored to their original condition and accordingly canceling any program execution when such a condition is judged.
摘要:
There is disclosed a control unit of a computer system comprising a volatile storing device for holding written data while the power is on, a non-volatile storing device for holding the written data even when the power is off, and a power-off preserving device for powering off after transferring the data held in the volatile storing device to the non-volatile storing device. The control unit of the computer system further comprising a power-on resuming device for returning the data held in the non-volatile storing device to the volatile storing device. There is also disclosed a control unit of a computer system comprising a non-resumable condition judging device for judging whether the status of the computer system meets the process non resumable condition or not when the powering off operation is directed, and a non-resumable condition informing device for informing the user that the status has been judged to meet the condition.
摘要:
A control unit for a computer system regulates the removal of power from the computer system when a user's power off signal is received in correlation with a process control table monitoring those programs in use in a volatile memory. The volatile memory is supplemented with a temporary storing means for reserving certain types of computer programs when the computer system is turned off. The status of a program is determined upon receiving a power off signal and a decision is made on the storage of the program in a temporary storage memory of limited space.
摘要:
A control unit of a computer system comprising a process resuming device for resuming the execution of the program it was running before the powering off operation by resuming the previous contents stored in a memory device containing registers in CPU, registers in input/output control units, and a volatile memory there were before the powering off operation, a non-resumable condition judging device for judging whether the status of the computer system meets the substantially non-resumable condition or not even the stored contents in the storing device has returned to the previous status at the powering back on, and either one of a program execution control device for restarting the execution of a program from the beginning at the powering back on according to the judged results by the non-resumable condition judging device, or a power control unit for powering off after the process has been judged to be in the substantially resumable status by the non-resumable condition judging device. There is also disclosed a construction in which programs loaded by a volatile memory are preserved to a storing device capable of holding data even when the power is off according to the executing status. There is also disclosed a construction in which data exceeding the capacity of the storing device is preserved to a hard disk or the like.

A multimedia data reproduction apparatus comprising an optical disk library containing a plurality of optical disks and a plurality of optical disk drives, a file management unit for managing names of motion picture files stored in the respective optical disks, a media management unit for managing whether each of the optical disks is being used or not, a drive management unit for managing whether each of the optical disk drives is being used or not, an open processing unit for deciding whether to accept a request to start reading or reject it according to information from the file management unit, media management unit and the drive management unit, a close processing unit for performing close processing of a motion picture file for which a request to end reading is issued, a data readout control unit for reading motion picture data in response to the request to start reading, and a network control unit for controlling communication between the above-mentioned units and terminal PCs 20. In this apparatus, it is possible to continuously reproduce motion pictures from the optical disk library.
摘要:
A virtual file management system constructed with a plurality of servers and a plurality of terminals that share file services provided by said servers, is that a virtual file management apparatus operating in at least one of said plurality of servers is provided that has: a management table which manages files stored on said plurality of servers by using virtual file identifiers, and in which a server name of a server where real data is stored and a real file identifier in said server are stored as a set for each of said virtual file identifiers; a receiving section which receives a file access request from each of said terminals; a request analyzing section which checks said management table by using the virtual file identifier contained in the file access request received by said receiving section, and thereby determines the server where the real data of the requested file is stored; a transmitting section which transmits data; and a request modification processing section which modifies said file access request so that a response to said file access request can be sent back to the terminal that issued said access request, directly from the server determined by said request analyzing section, and which instructs said transmitting section to transmit said modified file access request to said determined server, andsaid plurality of servers each include a request processing section which receives the file access request transmitted from said transmitting section of said virtual file management apparatus, and processes said received file access request, and which transmits the processed result to said terminal at least when said file access request is a request to read file contents.

A data processing device for playing back a digital work reduces the processing load involved in verification by using only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on a DVD. In addition, the data processing device improves the accuracy of detecting unauthorized contents by randomly selecting a predetermined number of encrypted units every time the verification is performed.

The present invention relates to a method of manufacturing a micro reactor device that includes a tubular reactor (1) as a flow path, for allowing reaction species to react in the reactor (1). The micro reactor device is manufactured by forming a particle layer (2) on an inner wall of the reactor (1). The particle layer (2) can be formed by causing a dispersion liquid of particles to flow through the reactor (1) and drying. In this way, it is possible to provide a method of manufacturing a micro reactor device having an inner wall modified so that the reaction species can react more efficiently, and to provide the micro reactor device.

A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.
