  • Patent number: 9199324
    Abstract: A holding wrench includes a clamping assembly and a pair of handles. The clamping assembly includes a housing, a transmission gear, a first latching member, a second latching member, and an adjusting subassembly. The first latching member and the second latching member engage with the transmission gear. The adjusting subassembly includes an adjusting member, a pair of pushing members protruding from the adjusting member, and a pair of resisting members. The adjusting member defines a pair of latching grooves. The pair of pushing members is located between the first latching member and the second latching member. When the adjusting member is moved toward the second latching member, one of the pair of pushing member pushes the second latching member away from the transmission gear, and the pair of resisting members latches into the pair of latching grooves, thereby positioning the adjusting member.

  • Patent number: 8966171
    Abstract: An access optimization method for a main memory database based on page-coloring is described. An access sequence of all data pages of a weak locality dataset is ordered by page-color, and all the data pages are grouped by page-color, and then all the data pages of the weak locality dataset are scanned in a sequence of page-color grouping. Further, a number of memory pages having the same page-color are preset as a page-color queue, in which the page-color queue serves as a memory cache before a memory page is loaded into a CPU cache; the data page of the weak locality dataset first enters the page-color queue in an asynchronous mode, and is then loaded into the CPU cache to complete data processing. Accordingly, cache conflicts between datasets with different data locality strengths can be effectively reduced.

  • Publication number: 20140033066
    Abstract: Disclosed in the present invention are a method and a device for uploading and downloading files, which belongs to the technical field of computers. The method for uploading files includes, judging whether a local file which is dragged and stopped by a user is entering an activation area of a network file folder, prompting the user to choose whether the user confirms uploading the local file to the network file folder or not if it is, uploading the local file to the network file folder if a confirming uploading information chosen by the user according to the prompt is received. The method for downloading files includes, judging whether a network file dragged and stopped by the user is entering an activation area of a local file folder, prompting the user to choose whether the user confirms downloading the network file to the local file folder or not if it is, downloading the network file to the local file folder if a confirmation of downloading chosen by the user is received according to the prompt.
