摘要:
An image forming apparatus includes a main controller for controlling the operation of the entire apparatus, an operating section for setting print jobs, a scanner for reading a document, and a printer for printing print data. The main controller includes an HDD serving as a storage device and a main CPU serving as a data processing section. The HDD includes a data-storage region divided into multiple subregions for storing print data and a file-management region for storing file-management information on the print data stored in the data-storage region. The main CPU divides the print data to be stored in the HDD into multiple data units, stores the multiple data units into multiple subregions of the HDD in a distributed manner, stores the file-management information on the multiple data units into the file-management region, and erases the file-management information stored in the file-management region after completion of the print jobs.
摘要:
In a storage device having redundant input/output paths, both a transmission data amount and a reception data amount are smoothed among paths. A storage device predicts not only a transmission data amount to be formed by an output request in a transmission queue but also a reception data amount to be formed by an input request in the transmission queue. The storage device stores a newly occurred output request in a queue having a minimum predicted transmission data amount and stores a newly occurred input request in a queue having a minimum predicted reception data amount. In a storage device having redundant input/output paths, transmission data amounts and reception data amounts can be smoothed among the paths.

摘要:
A method is provided with which a name of a virtual port is not changed when virtualized storage is moved among switches. Information about a creator and a borrower of name information is added to a table including name information and address information of a virtual port of a name server managing the name information and the address information. The name information is provided to plural switches and managed. In addition, name information, which can be used commonly among name servers managing the name information and the address information is pooled in advance, and the name information of the virtual port is borrowed from there.
摘要:
A continuous casting method and apparatus therefor wherein a reaction force/reduction controller selects a pivot reduction roll such that the thickness of the solidified shell of the cast slab having a liquid core is equal to the target thickness T.sub.ref, and calculates a difference between a thickness T.sub.in of the cast slab having a liquid core at the inlet of the reduction roll zone PRT and the target thickness T.sub.ref, i.e., .DELTA.T. The resulting value of .DELTA.T, i.e., a target reduction is provided to the reduction controllers 2 of the pivot reduction roll. The reaction force/reduction controller 1 assigns target reductions 1/3 .DELTA.T and 2/3 .DELTA.T to the two reduction rolls upstream of the pivot reduction roll. The reaction force/reduction controller 1 calculates a target pressure (P.sub.i +.alpha.) on the basis of the selected value for .alpha., and the resulting target pressure (P.sub.i +.alpha.) is provided to each of the reduction controllers 2 of the reduction rolls, downstream of the pivot reduction roll.

An integrated submerged entry nozzle for thin slab continuous casting has a plate member 12 corresponding to the lower plate of a slide gate and a nozzle member 11 having a flat molten steel passage section in the part to be submerged into molten steel of at least the tip, the both 11. 12 being integrated together by the use of an organic adhesive. The plate member 12 and the nozzle member 11 are separately formed followed by baking or firing, the both 11, 12 are adhered together by the use of an organic adhesive, the adhesive is dried, the outside is covered with a shell, and refractory mortar is filled in the space. Thereafter, a refractory ring 28 is adhered in such a manner as to cover the inside of the adhesive joint part followed by drying.

In a flat casting nozzle 10 having a taper 13, the position of the terminal end 14 of the taper 13 formed on the long edge side and the position of the terminal end 17 of a taper 16 formed on the short edge side are mutually shifted.
摘要:
A thin slab that is free of internal cracks is formed by reducing a continuously cast strand having a liquid core. The placement of the reduction rolls is controlled to effect a suitable amount of reduction. The methods effectively reduce bulging strain, as well as strain associated with reduction of the strand. As a result, total accumulated strain is reduced and a thin slab free of internal cracks can be manufactured at high speeds. The apparatus includes reduction blocks which are capable of shifting the rotation angle of an upper roller segment frame. Misalignment strain is reduced and the thickness of the strand can be changed without stopping the manufacturing operation.
摘要:
A multiprocessor bridge construction allows ports that are operable under a spanning tree protocol to coexist with ports that are inoperable under the spanning tree protocol, thus making it possible to improve the frame-repeating capability of the bridge, to equip the bridge with a large number of ports, and to divide the spanning tree topology into a plurality of portions to be managed.
