  • Publication number: 20100191749
    Abstract: A method of externally sorting large files in a computer system is presented. The contents of the input file to be sorted are investigated in order to identify presorted portions thereof. The presorted portions of the input file as thus identified are incorporated as sorted strings into an external sortwork file, by rearranging directory information rather than physically transferring data. If merging is necessary, the data may then be merged by a procedure wherein blocks of sorted data to be merged are incorporated into an output (sortout) file, by rearranging directory information rather than physically transferring sorted blocks to the sortout file. As a result of the process, portions of sorted data incorporated into the sortout file may physically remain in external storage space allocated to the input file, and/or in external space allocated to sortwork, thereby eliminating or reducing reading and writing from disk during sort-merge processing.

  • Publication number: 20100155205
    Abstract: A connector structure of waterproof and explosion-proof button is provided. A waterproof element completely covers the connecting part of the connecting element. By pressing a first button bar of the waterproof element, a second button bar is driven to depress the button therein. A companion part inside the connecting element is connected and fixed with an explosion-proof element. The connector structure thus achieves the waterproof and explosion-proof effects and has the button function at the same time. The structure solves the problem of having too many elements and too complicated assembly process for achieving the waterproof effect in the prior art. According to the structure, the assembly of the connector structure is simple and both waterproof and explosion-proof effects are simultaneously achieved.

  • Patent number: 7723181
    Abstract: A small-size (w<0.5 micrometers) alignment mark in combination with a “k1 process” is proposed, which is particularly suited for the fabrication of trench-capacitor DRAM devices which requires highly accurate AA-DT and GC-DT overlay alignment. The “k1 process” is utilized to etch away polysilicon studded in the alignment mark trenches and to refresh the trench profile, thereby improving overlay alignment accuracy and precision.

  • Patent number: 7673911
    Abstract: A safety type quick connector has a body, a socket base, a moving base, a pushing assembly, an outer sleeve, multiple springs, multiple first balls and second balls. The socket base is connected to the tubular body and has an inserting end, a connecting end, multiple ball slots and ball bores. The moving base is movably mounted in the socket chamber and has a closed end, an open end, a sealing flange, multiple ball holes and at least one vent. The sealing flange is formed around the closed end and abuts against and closes the connecting end of the socket base. The pushing assembly is movably mounted in the moving base. Accordingly, the moving base can be kept stationary when a plug is inserted into the connector and pushes the pushing assembly to move, and this can keep air from leaking.

  • Publication number: 20090222496
    Abstract: Facility for using images created by backup software to recreate an entire machine as it was at the point in time in the past when the backup was taken. The facility can be extended so as to bring up a set of machines which together serve some logical business function as in a cluster or federated servers, and further extended so that an entire data center may be virtualized from backup images. The virtualized servers provided may serve as an alternate data center standing in case of disaster or to meet maintenance windows achieving low cost Instant Disaster Recovery. A set of virtual machines may stand in for physical machines for a period of time and then resynchronized or re-seeded to physical machines via a combination of bare metal recovery and re-synchronizing from live LXJNs that form the virtual machine disks.
