    摘要： Disclosed are polyester multi-filamentary yarn useful as a reinforcement for tires and a dipped cord formed therefrom. The polyester multi-filamentary yarn comprises at least 90 mol % of polyethylene terephthalate and has an intrinsic viscosity of 0.70-1.2 and a tenacity of 5.5-8.5 g/d with an intermediate elongation difference (E1−E0) between intermediate elongations E0 and E1 amounting to 6% or greater. The polyester dipped cord is produced by subjecting at least two strands of polyester multi-filamentary yarn to first twisting and second twisting, the polyester multi-filamentary yarn comprising 90 mol % of polyethylene terephthalate; forming the strands into a fabric; and treating the fabric with blocked isocyanate and resorcinol formaldehyde latex (RFL), wherein the cord satisfies the following characteristics: a) a tenacity of 5.0 g/d or greater, b) a dimensional stability index (E4.5+SR) of less than 7.0%, c) a breaking elongation of 9% or greater, and d) an intermediate elongation difference (E1−E0) of 3% or less. Showing a harmony of high elastic modulus and low shrinkage, the filamentary yarn and dipped cords are superior in dimensional stability and fatigue resistance, so they can be used as reinforcements for rubber composites such as tires.

    摘要： A mobile Internet access point is disclosed that connects a wireless LAN terminal to a mobile Internet. The mobile Internet access point includes: a plurality of mobile Internet access units, a wireless LAN access unit, and a converting unit. The mobile Internet access units communicate with one or more base stations, respectively, and are connected to a mobile Internet. The wireless LAN access unit is connected to one or more wireless LAN terminals that can be connected to a wireless LAN and manages connected wireless LAN terminals. The converting unit converts wireless data, received by the wireless LAN access unit, into mobile Internet data following the protocol of the mobile Internet. The converting unit also converts mobile Internet data, received via the plurality of mobile Internet access units, into wireless LAN data following the protocol of the wireless LAN. Therefore, although one of the mobile Internet access units does not work, the remaining mobile Internet access units can continue communicating with the base stations, thereby providing services to the wireless LAN terminal without interruption.
