Title: Storage device, storage system, memory managing method, and recording medium
Inventor: TAKAHASHI TSUYOSHI
IPC: G06F3/06
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce frequency in generating address conversion tables when accessing data. SOLUTION: A CPU 121 prepares a file managing block search index(BSI) and a file managing block pointer table(BPT) for a zone 0 of a flash memory 11 storing directories and a file allocation table(FAT) and stores these BPT and FAT in a static random access memory(SRAM) 123. When a readout request is outputted from a computer 2, the CPU 121 specifies and reads out a directory and a position of the FAT on the basis of the BPT and supplies the readout contents to the computer 2. In the case of accessing data in another zone, a general BPT is newly generated but the file managing BPT is not updated. Even when any zone includes data accessed immediately before, accesses to the directory and the FAT are executed without generating a new BPT again.

Title: Method of carburizing steel product
Inventor: KANO KUNIHIKO
IPC: C23C8/22
Filed: 1988-05-11
Abstract: PURPOSE:To shorten the tie for a carburizing operation without requiring a carburizing device and a carburizing agent by forming a mold coat by a mold coating liquid to the outside of foamed polystyrene, thereby constituting a specific expandable pattern. CONSTITUTION:The pattern 3 is formed of the formed polystyrene having at least 0.8 pond per square foot in density and the mold coating liquid having at least >=45Be concn. is used for the mold coat 4 to be coated on the outside thereof. A molten steel or steel alloy 8 passes a runner 5 through a sprue and arrives at the pattern 3 to gasify and expend the pattern 3 when the molten steel or steel alloy 8 is supplied to the sprue. The gas generated on the expenditure of the pattern 3 passes the layer of the mold coat 4 and emerges to the upper part of a flask 1 by passing the spacings of a packing material 2. However, a part of the gaseous hydrocarbon stays on the inner side of the mold coat 4 and exerts influence to the cast product. The carbon in said gas in particular penetrates to the inner side of the cast product in the mold and the carburization is effected upon lapse of time. Since the time for removing the mold coat 4 from the cast product after the casting is at least 5 minutes and, therefore, the carburized layer of at least 0.5mm depth from the outside surface of the product is obtd. by the carbon in the gas.
