  • Patent number: 7153701
    Abstract: A method for quantitatively detecting an antigen which comprises (1) a first step of providing an Fab? antibody having a uniform isoelectric point, said antibody forming an immune complex with an antigen in an analytical sample and being modified by adding an amino acid sequence comprising a charged amino acid residue and by being labeled with a fluorescent dye, (2) a second step of mixing the Fab? antibody having a uniform isoelectric point with the analytical sample containing the antigen to obtain a mixture comprising the immune complex, (3) a third step of separating the mixture by performing electrophoresis in a carrier, (4) a fourth step of irradiating an excitation light which excites the fluorescent dye to the mixture separated in the third step to cause fluorescence in the immune complex, and (5) a fifth step of detecting the fluorescence.

  • Publication number: 20040190183
    Abstract: Data blocks and redundant data are distributed across disk drives. In response to a first read request transmitted from a host device, a controller issues second read requests to read the data blocks and the redundant data from the disk drives. Further, the controller detects the disk drive which is no longer required to read the data block or redundant data from among the disk drives, and issues a read termination command to the detected disk drive to terminate reading therefrom. In a disk array device with such structure, even reading of one parity data with much time required does not affect other reading.

  • Patent number: 6750680
    Abstract: There is provided a semiconductor integrated circuit, a logic operation circuit and a flip flop capable of operating at a high speed and having a leak electric current reduced. In a semiconductor integrated circuit according to the present invention, only a gate circuit on a critical path is constituted by an MT gate cell obtained by combining transistors having a low threshold voltage with transistors having a high threshold voltage, and any other gate circuit is constituted by a transistor having a high threshold voltage. Consequently, the gate circuit on the critical path can be operated at a high speed, and the overall leak electric current can be suppressed, thereby reducing the consumption power.

  • Patent number: 6714986
    Abstract: When a get resource message arrives from an exterior, a resource allocation part reserves a resource. In case of data reading or data writing, a declared value management part checks parameters and a slot allocation part allocates the resource, thereby constructing an efficient file system guaranteeing delay quality in relation to data reading. As the result, it is possible to provide a file system providing pictures in a quick response time for requests from users and supporting users requiring various regeneration speeds.

  • Patent number: 6408359
    Abstract: A configuration managing part stores the number of storage devices and respective identifying information. An empty area managing part stores empty-block addresses for each storage device. A destination determining part recognizes the number of storage devices with the information stored by the configuration managing part, and fetches one or more empty-block addresses for specifying empty storage areas included in each storage device from the empty area managing part. The destination determining part then repeatedly rearranges the empty-block addresses at random to determine destination of data.

  • Patent number: 6397258
    Abstract: A file system capable of performing bandwidth setting is realized. Further, a bandwidth assuring function and a prefetching function are added thereto, and are organically coupled to a bandwidth setting function, thereby realizing a real-time remote file system. For these purposes, a bandwidth setting request issued by an application 302 is fed to a bandwidth setting part 305 through an extended API 313. The bandwidth setting part 305 sets bandwidths, respectively, for transmission bandwidth control parts 311 and 314 and a prefetching amount control part 310. The transmission bandwidth control parts 311 and 314 and the prefetching amount control part 310 respectively control a transmission bandwidth and control the amount of prefetching on the basis of the bandwidths respectively set.
