摘要:
A controller for a storage device is connected to a host system and the storage device. A buffer memory includes first and second storage areas. A timer counts a preset given time in response to an instruction to start counting and sends a deadline notification when A given time is elapsed. A command responding portion, when receiving a read command from the host system, instructs the timer to start counting and thereafter outputs a read instruction to read data from the storage system. A data processing portion, in response to the read instruction by the command responding portion, reads specified data from the storage device and holds the read data in the second storage area of the buffer memory. A read control portion sends the host system the data held in the second storage area of the buffer memory when the deadline notification is received from the timer.

To achieve both information confidentiality management and early discovery of information leak.A file encrypting/decrypting program makes a computer execute a process including a step of creating a session key (a1); a step of encrypting a file (f1) with the key (a1), thereby creating a file (f2); a step of encrypting the key (a1) with a public key (b1), thereby creating a key (a2); a step of encrypting the key (a1) with a public key (c1), thereby creating a key (a3); and a step of creating a combined file (f3) including the file (f2) and the keys (a2, a3); and a process including a step of separating the file(f3) into the file (f2) and the keys (a2, a3); a decrypting step of decrypting the file (f2) into the file (f1) with the key (a1); a step of decrypting the key (a2) into the key (a1) with a private key (b2) corresponding to the key (b1) and then proceeding to the decrypting step; and a step of decrypting the key (a3) into the key (a1) with a private key (c2) corresponding to the key (c1) and then proceeding to the decrypting step.

For a control apparatus to be boundary scan testable even when running, including processor cores in an operator to be capable of self-repairing a troubling part, an operator (2) has processor cores (2a, 2b) connected to a boundary scan bus (12), and adapted to mutually diagnose opponent processor cores for troubles, by boundary scan testing each other in a time-dividing manner.

A turntable, swing hammers and fixed teeth of a garbage disposer are combined with a cylindrical pipe in one body, and arranged to be attachable/detachable with respect to a hopper. A guide pipe branching upward from an upstream upper end portion of a S-trap formed in a drainage pipe in the garbage disposer is provided, and a water injection nozzle is set on the guide pipe.

The process involves stripping ammonium nitrogens and organic materials, as gases, which are present in process waste waters to be discharged from plants wherein gases for use in ammonia synthesis are manufactured by reforming hydrocarbons with steam, decomposing the organic materials selectively in the presence of a catalyst at a temperature of about 120.degree. to 400.degree. C., mixing the remaining gases with the flue gases from said plants so as to provide a gaseous mixture having ammonia therein in an amount of about 0.3 to 10 moles per mole of nitrogen oxides present in the flue gases, reacting the gaseous mixture over a catalyst at a temperature of about 150.degree. to 700.degree. C. and oxidizing the unreacted ammonia, if any, in the presence of a catalyst at a temperature of about 150.degree. to 700.degree. C. to render the nocuous substances innocuous.
摘要:
According to one embodiment, a controller for a storage apparatus is disclosed having interfaces connectable to a host system, a first storage apparatus and a second storage apparatus. A data in the first storage apparatus and a data in the second storage apparatus are duplicates. A status table stores the operating state regarding the first storage apparatus and the second storage apparatus, wherein the operating state indicates among writing, reading, or standing by. A monitor monitors the interfaces and set up the operating state into the status table. A buffer memory buffers the data for writing in the first storage apparatus and the second storage apparatus. A command response unit receives the data for writing and write-in request from a host system, and directs the writing of the data to the first storage apparatus and the second storage apparatus while making the buffer memory buffer the received data.
