Abstract:
Provided are a method for authenticating a user terminal in an interface server, and an interface server and a user terminal using the same. The method includes receiving authentication request information from an application service providing server in order to request the interface server to authenticate the user terminal receiving an application service provided from the application service providing server, authenticating the user terminal according to the authenticating request information using an authentication method selected by the interface server or a user of the user terminal, and transmitting authentication response information including an authentication result of performing the authentication method to the application service providing server. The interface server provides an interface for a network to the application service providing server.
Abstract:
Disclosed are a non-aqueous electrolyte solution for a lithium secondary battery and a lithium secondary battery comprising the same. The non-aqueous electrolyte solution for a lithium secondary battery comprises a silicon-based compound represented by a specific chemical formula and having both a hydroxyl group and a hydrocarbon group having a carbon-carbon double bond. When it is applied to a lithium secondary battery, the non-aqueous electrolyte solution improves deterioration of cycle life characteristics occurring after repeated charge/discharge cycles and prevents swelling phenomena by suppressing a decomposition reaction of an electrolyte solution even when a battery in a fully charged state is stored at high temperature or is charged/discharged, thereby enhancing the life characteristics at high temperature.

Abstract:
A dual stack mobile communication system is provided for building a single interworking network of an asynchronous network and a synchronous network. A single node is formed by combining the same kind nodes of the asynchronous network and the synchronous network, wherein the single node searches information for generating two output signal points according to a synchronous protocol and an asynchronous protocol in one input signal point according to the synchronous protocol or asynchronous protocol, and generates one output signal point.
Abstract:
A mask is provided. The mask includes a mask body, a first exposing part and a second exposing part. The first exposing part is on the mask body. The first exposing part includes a first light transmitting portion and second light transmitting portions. The first light transmitting portion exposes a portion of the photoresist film corresponding to the output terminal to a light of a first light amount. The second light transmitting portions exposes an adjacent portion of the photoresist film adjacent to the output terminal to a light of a second light amount smaller than the first light amount. The second exposing part is on the mask body. The second exposing part includes third light transmitting portions for partially exposing the photoresist film corresponding to the storage electrode to a light of a third light amount that is between the first and second light amounts.
Abstract:
A non-aqueous electrolyte solution for a lithium secondary battery comprises a lithium salt and an organic solvent. The non-aqueous electrolyte solution further comprises a specific siloxane compound and a sulfonate compound. This non-aqueous electrolyte solution solves the capacity degradation phenomenon, which appears in a lithium secondary battery using a non-aqueous electrolyte solution containing only a specific siloxane compound when the lithium secondary battery is used for a long time, so this non-aqueous electrolyte solution is especially useful for high-capacity batteries.
Abstract:
A lithium secondary battery comprises an anode capable of intercalating or disintercalating lithium ions, a cathode configured with a lithium-containing oxide, and a nonaqueous electrolyte solution. The lithium-containing oxide comprises a lithium nickel based oxide. The nonaqueous electrolyte solution comprises vinyl ethylene carbonate (VEC) and a mono-nitrile compound. This lithium secondary battery solves the deterioration of charge/discharge cycle characteristics caused by a lithium nickel based oxide used for a cathode, and also controls the decomposition reaction of electrolyte to solve the swelling phenomenon even though the battery is stored at a high temperature or charged/discharged in a fully-charged state, thereby improving high-temperature life characteristics.
