  • Publication number: 20140239545
    Abstract: Disclosed are a mold and a method of manufacturing a mesh-integrated filter using the same. The mold includes a lower body; a protruding pin provided to the lower body to protrude upward; a plurality of sliders slidably disposed on the lower body to move forward and surrounding a circumference of the protruding pin; an upper body covering upper sides of the sliders and having an injection hole formed therethrough such that a liquid resin is injected into a gap between the protruding pin and the sliders through the injection hole; and a shaping portion for forming a mesh-integrated filter upon hardening of the liquid resin. The mold can form a mesh-integrated filter in a closed state to improve productivity by eliminating a separate process for assembling a mesh and a filter.

  • Publication number: 20070220133
    Abstract: The present invention is directed to a method for correcting time data in a network management application. In a conventional Simple Network Management Protocol (SNMP) application, time errors occur due to a time tick or a time delay in the network. To resolve the above problem, the present invention suggests a method for correcting the time data, wherein the network management application waits for the most polling periods to save system resources, checks time data for the last polling period, and requests performance information and statistic information. With the present invention, the possibility of incurring time errors due to the information request for polling can be resolved.
