Abstract: 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.

Abstract: A Worldwide Interoperability for Microwave Access (WiMAX) integrated network server is disclosed. The WiMAX integrated network server is integrally includes an Access Service Network Gateway (ASN-GW), an Authentication Authorization Accounting (AAA) connected to the ASN-GW, and a Home Agent (HA). The ASN-GW follows the WiMAX standard, manages a mobile station connected to a base station, and provides connection paths connected to a network. The AAA authenticates the mobile station to be connected to the network. The HA provides a Mobile IP service to guarantee the mobility of the mobile station. The WiMAX integrated network server includes a separate data processing unit, which makes it possible to rapidly process data. The WiMAX integrated network server can independently manage communication among the mobile stations connected thereto, separately from an external network. The WiMAX integrated network server does not require additional equipment, which reduces the installation space and costs.

Abstract: An engaging structure of a support plate and an outer tub which fixes a piston rod. The outer tub and the support plate are firmly fixed by the simple bending and curling. First pieces and second pieces are formed by minutely cutting the surface of a lower end of the outer tub in a same axis as the outer tub. The first pieces are bent by rolling the first pieces towards the inner side of the outer tub. A support plate is positioned on the bent first piece. The second pieces are fixed by curling the first pieces towards the support plate.

Abstract: The present invention relates to an engaging structure of a support plate and an outer tub which fixes a piston rod. The outer tub and the support plate are firmly fixed by the simple bending and curling. First pieces and second pieces are formed by minutely cutting the surfac3e of a lower end of the outer tub in a same axis as the outer tub. The first pieces are bent by rolling the first pieces towards the inner side of the outer tub. A support plate is positioned on the bent first piece. The second pieces are fixed by curling the first pieces towards the support plate.
