  • Publication number: 20240134575
    Abstract: The storage system is a storage system comprising a plurality of storage nodes each including a non-volatile storage device, a storage controller that processes data read/write to the storage device, and a volatile memory, in which the storage controller stores data related to the data write in the memory, stores data that needs to be non-volatile among the data stored in the memory as log data in the storage device, makes the log data stored in the storage device redundant among a plurality of storage nodes, and performs a recovery process for the log data when a problem occurs in the log data stored in the storage device of one of the storage nodes.

  • Patent number: 11954155
    Abstract: An information processing device according to the present application includes a generation unit and a providing unit. The generation unit uses a model that is trained to learn a relationship between a criterion for classifying users of a first company and a criterion for classifying users of a second company to generate a criterion (common key) for classifying the users of the second company into a first category, from the criterion for classifying the users of the first company into the first category. The providing unit provides a criterion generated by the generation unit.

  • Publication number: 20220242155
    Abstract: Provided is an ink jet recording method that enables recording of an image with a wide expressible color gamut and high fluorescence intensity. The ink jet recording method comprises a step of recording an image by applying first and second inks to a recording medium by using an ink jet recording apparatus, including a recording head having ejection orifices configured to eject the first and second inks, respectively, such that an area where the first ink is applied and an area where the second ink is applied at least partially overlap each other. The first ink contains an alkaline buffer and a pigment particle dispersed by an effect of an anionic group, the second ink contains a fluorescent particle dispersed by an effect of an anionic group, and a density ?1 (g/cm3) of the pigment particle is more than a density ?2 (g/cm3) of the fluorescent particle.

  • Patent number: 6766244
    Abstract: A technology is provided for timely reporting on vehicle positions to a control center without unnecessary spending on communication costs. The positions of a plurality of moving bodies which are being managed are detected. Determinations are made on whether or not the positions of these moving bodies are within specified multi-stage distance ranges. As a result of this determination, when the position of the moving body enters into a distance range for one of the stages, the position of this moving body is wirelessly reported to a control center.

  • Patent number: 6528708
    Abstract: The present invention provides an exterior structure for an electronic keyboard instrument which has excellence in an outward appearance and which can be produced easily without detracting acoustic characteristics. In the present invention, a recess groove 9 extending in a direction in which keyboards 3 are arranged is formed at an upper portion of a back panel 4 of the electronic keyboard instrument 1, a locking edge 8a formed at an upper edge of a speaker cover 8 is fitted into the recess groove 9, and a lower edge of the speaker cover 8 is fixed to a lower portion of the back panel 4 by a screw 11. A lower portion of the back panel 4 is provided with a positioning stopper 4d which abuts against a back surface of a keybed 12 of the electronic keyboard instrument 1, and a fixing piece 4e which abuts against a lower surface of the keybed 12. A thick plate 14 having rigidness is provided around the periphery of the speaker-mounting hole 6.

  • Publication number: 20020123840
    Abstract: Embodiments of the present invention are directed to a technology for timely reporting on vehicle positions to a control center without unnecessary spending on communication costs. The positions of a plurality of moving bodies which are being managed are detected. Determinations are made on whether or not the positions of these moving bodies are within specified multi-stage distance ranges (S100 to S200 to S500). As a result of this determination, when the position of the moving body enters into a distance range for one of the stages, the position of this moving body is wirelessly reported to a control center 200 (S600).

  • Patent number: 5306645
    Abstract: Methods of conducting Thin Layer Chromatography (TLC) involving using a TLC plate having sample spots and including no support material, placing the TLC plate on a porous substrate, and allowing solvent to move upwardly from the porous substrate toward the TLC plate by capillary action to be vaporized from the surface of the TLC plate, thereby concentrating the sample spots developed in the thin layer on the surface of the TLC plate.
