  • Patent number: 6168721
    Abstract: The present invention relates to a process for the treatment of arsenic-containing sludge obtained by adjusting arsenic-containing waste water to a PH of 12 or greater by the addition of a calcium compound and subjecting the waste water to solid-liquid separation, the process comprising the steps of adding a calcium compound to the arsenic-containing sludge slurry obtained by the solid-liquid separation, dewatering the resulting sludge, drying the dewatered sludge, and calcining the dried sludge. According to the present invention, arsenic-containing sludge obtained by treating waste water to precipitate arsenic present therein can be calcined to yield a calcined product which involves no risk of arsenic redissolution when it is dumped. Moreover, there is no possibility that arsenic compounds may be volatilized during calcination.

  • Patent number: 6018790
    Abstract: For the high-speed data access machine, data is distributed in a plurality of hard disk drives coupled to slave processors to achieve ever-higher data reliability and maintenance. One master processor is provided with a plurality of slave processors, each of which is coupled to two hard disk drives containing the same data. A synchronous signal permits two hard disk drives to operate in synchronous rotation in half-a-turn phase difference from each other. The hard disk controller writes the same data in both hard disk drives but reads data from whichever hard disk drive requires less access time to obtain the data. A plurality of hard disk drives holding exactly the same data improves data reliability. Also, by rotating a plurality of hard disk drives in different phase, the rotational delay in data access is cut by half.

  • Patent number: 5930817
    Abstract: A data storage managing system and method in which a HOST system obtains operation information of a storage device from a system connected to a network without the need for a specific device driver are disclosed. When disks shared between systems connected to the network are managed by a disk manager, monitoring and control information for the shared disks may be accessed by a file access command of the operating system on the HOST system. An operation information storage device is formed in a file format which can be accessed by a file access command of the operating system on the HOST system and the HOST system reads the operation information of the storage devices stored in the operation information file according to the file access command. The information to control the operation of the storage devices is written in the operation information file according to the file access command.

  • Patent number: 5915081
    Abstract: The present invention relates to an arrayed recording apparatus having spare devices for replacing faulty disk drives. Each of the SCSI controllers in the arrayed recording apparatus connects to a driver/receiver and further connects to spare disk drives. Each of the SCSI controllers accesses the spare disk drive by setting a receive/enable signal effective to the driver/receiver. Unused ID numbers are assigned to the spare disks. If a disk drive develops a fault, the RAID controller RC requests the SCSI controller to replace the faulty disk drive with the spare disk drive.It is possible to attain the function of the hot stand-by system without comprising a specific spare controller.

  • Patent number: 5901280
    Abstract: A transmission monitoring and controlling apparatus is provided between a first system and a second system. The transmission monitoring and controlling apparatus monitors information transmitted through a Fibre Channel. Then, a back controller analyzes the monitored information and stores the information in a controlling memory based on the analysis. For example, when the first system writes data on the second system, the back controller stores the data in the controlling memory. Therefore, even if a failure has occurred in the second system, the transmission monitoring and controlling apparatus is able to read the data from the controlling memory and send the data to the first system instead of to the second system.

  • Patent number: 5878203
    Abstract: A recording device which improves a response time to write data by reporting to a host computer the completion of writing operation prior to the completion of writing redundancy data. Data writing command information from the host computer is stored in a command/status memory backed up by a power source in an array controller, and the completion of writing operation is reported to the host computer at the time of the completion of writing updated data prior to the completion of writing redundancy data. Redundancy data is written as a background process. If redundancy data could not be written due to any abnormality of the power source or the like, such redundancy data may be generated from the data in other disk units of the same redundancy group in accordance with writing command information stored in the command/status memory, thereby completing the writing of redundancy data.

  • Patent number: 5840194
    Abstract: The present invention provides a process for treating arsenic-containing waste water, comprising adding an oxidizing agent, if necessary, to arsenic-containing waste water to oxidize trivalent arsenic in the waste water into pentavalent arsenic; adding a calcium compound to adjust the pH to 12 or higher; separating it into solid and liquid (first solid/liquid separation); calcining the resulting sludge, while adding a ferric salt to the treated solution to adjust the pH to 6-9 after the solid/liquid separation; and separating it into solid and liquid (second solid/liquid separation). According to the present invention, it is possible to remove arsenic from waste water efficiently to yield treated water satisfying various tolerance limits under various regulations, while the arsenic-containing sludge separated from the waste water can become harmless in subsequent continuous steps.

  • Patent number: 5758057
    Abstract: In case of consecutive transmission of a large amount of data such as dynamic image data, a multi-media storage system of the invention generates and transmits data stored in a faulty disk drive when one of a plurality of disk drives being faulty caused by an internal calibration or an error of the disk drive and the faulty disk drive does not respond within a predetermined length of time set in a timeout table. The multi-media storage system cancels an access to the faulty disk drive, generates data to be read from the faulty disk drive based on data stored in the other disk drives of the plurality of disk drives and the redundant data and continues to transmit data.

  • Patent number: 5737745
    Abstract: In a redundant array of disks, the disks are divided into areas of different sizes, so that small amounts of data can be stored in an area of an appropriate size on a single disk, instead of being spread over multiple disks. A usage status table indicates which areas are in use. Check information is generated and stored only for areas indicated to be in use. When new check information is generated, it is therefore possible to omit the reading of unnecessary old data and old check information. When a disk fails and is replaced with a standby disk, only the data in areas indicated to be in use are reconstructed. Check information can be stored on a solid-state disk.
