  • Patent number: 5983324
    Abstract: When the OS judges that a read request to the secondary storage device from the user process is the sequential access, the OS judges whether prefetching is to be stopped before the data succeeding to the data designated by the request is prefetched, so as to decrease replacement of data prefetched to the main memory by other data before the data is used. The judgment is executed to prevent that succeeding data from being replaced by other data after the succeeding data is prefetched to the cache area in the main memory. That is, it is judged whether the data requested by the read request has already been prefetched, and has already been replaced by other data before the requested data is used by the user process, if the requested data has been prefetched. When these two conditions are met, prefetch is useless. The prefetching accompanying this read request is not executed, the prefetch stop flag is set, and prefetching is prohibited to the succeeding sequential access by this prefetch stop flag.

  • Patent number: 5982181
    Abstract: An insulated device diagnosing system is capable of judging the deterioration, lifetime, and defects of a device. The intensity at each voltage phase angle is measured at a plurality of specific frequencies, taking high voltage phase angles as the abscissas. The deterioration, lifetime, and the kind and extent of abnormality of the device are judged from the pattern and intensity of the spectral distribution, which is obtained by peak-holding the measured intensity for a defined time period. According to the present invention, partial discharge can be measured highly sensitively and precisely to diagnose the deterioration, lifetime and the extent of defect of the device. As a result, the insulation reliability of the device can be improved, and the part of the device that should be repaired/replaced can be grasped before disassembly of the device, thereby cutting the maintenance cost.

  • Patent number: 5978890
    Abstract: In a data processing system in which main and sub disk storage devices are under the control of individual each disk control devices, the write processing time is reduced by selectively sending data according to the command-chaining time between main and sub disk control devices. A section for judging cable length and function of the sub disk control device 36 estimates command-chaining time between a pair of main and sub disk storage devices. The channel command analyzing section 31 estimates the number of records to be transferred and the length of a record using a LOCATE RECORD command. The command judgment section for the sub disk control device 32 optimizes the command-chain to be issued to the sub disk control device using the above-mentioned information. Then, the section for issuing command to the sub disk control device 35 issues the optimized command chain. Thus, a shorter transmission time is realized by either sending individual records or an entire track of data.
