  • Patent number: 7570447
    Abstract: There are provided a cache region that stores write data from a host device, storage media, a data storage region for the storage media, and a comparison unit. A first comparison object is generated for N items of write data on the cache region and the N items of write data are transferred to the data storage region. Write data is read from a designated address of the data storage region and this write data is written to the storage media. When N items of write data have been read, a second comparison object is generated in respect of the write data. The comparison unit compares the first comparison object and the second comparison object, and if the result of the comparison is a mismatch, the N items of write data on the cache region are again transferred to the data storage region.

  • Patent number: 6125818
    Abstract: A laminated fuel swirl element is employed, in which a strong swirl force flow is imparted to the fuel at a remote position relative to an injection hole, while on the other hand, at a position near the fuel injection hole, a weak swirl force is imparted to the fuel. A complex solid cone spray can be obtained in this way, which spray has a superior dispersion characteristic obtained by attracting small diameter droplets, which are generated at an outer peripheral portion of the spray, through a spray portion which is generated in the vicinity of a central area of the spray and has a large velocity.

  • Patent number: 6044353
    Abstract: A baggage ATM is provided at curbside at an airline terminal to allow passengers to check bags without the assistance of a baggage agent. The baggage ATM reads an identification card provided by the passenger to verify the passenger's reservation by accessing a passenger record in central storage, verifies the passenger identity by comparing graphic data obtained by fingerprint or retina scan with similar graphic data stored in the passenger record, and issues baggage tags bearing identifying data to the passenger for each bag to be checked. The identifying data on the baggage tags is stored in the passenger record. At the destination terminal, an exit gate is provided with a card reader which reads the passenger identification card to access the passenger record and a scanner that reads the identifying data on the baggage tags. If the identifying data read from a tag does not match the identifying data stored in the passenger record, the passenger is not allowed to leave with that bag.
