Abstract: An external storage medium management system takes into account the maintenance of data security in case an external storage medium has been taken out on emergency. It comprises an external storage medium device and an enclosure device, which is connected to a host side device and which accommodates the external storage medium device, the external storage medium device reports the result of authentication to the enclosure device in case authentication operation is done. On detection of extraction of the external storage medium device from the enclosure device, the external storage medium device of inhibits access to retained data and allows access to the data only in case the authentication in accordance with a preset system has met success.

Abstract: The present invention provides an early-maturing transgenic plant, which comprises a nucleic acid that encodes a protein having activity of causing early maturation of a plant, so that the gene can be expressed.

Abstract: A processor 1 provided with a plurality of cores, an interrupt operation dedicated core 20 which is used only for an interrupt operation; a normal core 11 to 1n which outputs an interrupt request when an interrupt source is generated; and an interrupt control part 30 which, upon receipt of the interrupt request, assigns an operation by an interrupt vector to the interrupt operation dedicated core 20.

Abstract: It is intended to provide for a polycistronic expression pattern in a plant used as a host. The present invention provides a polynucleotide which comprises the following DNA (a) or (b) and functions as IRES (internal ribosome entry site) in a plant: (a) DNA of the nucleotide sequence represented by SEQ ID NO: 1, 2, 3, or 4; or (b) DNA of a nucleotide sequence derived from the nucleotide sequence represented by SEQ ID NO: 1, 2, 3, or 4 by the substitution, deletion, addition, and insertion of one or more bases and having a function of positively regulating the translation of a gene located downstream along the translation direction in the plant.

Abstract: An apparatus of an exemplary embodiment of the present invention includes first and second memories and a storage unit. Further, an indication which indicates necessity of a memory dump is provided with the apparatus. A first unit boots the apparatus without using the second memory when the indication indicates the necessity of the memory dump. The apparatus has a second unit which copies the content of the second memory into the storage unit and a third unit which copies the content of the first memory into the second memory, wherein the content of the first memory is formed when the first unit boots the apparatus.

Abstract: A re-recording/re-reproducing device cleans both the magnetic tape and head of dregs which cause errors in writing and reading. A magnetic head records and reproduces input digital data to and from a magnetic tape at a normal speed. When an error in writing or reading the input digital data is detected, the tape is moved to a position where the error is detected and the magnetic head re-records/re-reproduces the input digital data to and from the magnetic tape, but does so at a speed higher than the normal speed of recording/reproducing, resulting in the removal of the dregs from the magnetic tape and head.
