摘要:
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.

The present invention discloses a dual stack mobile communication system for building a single interworking network of an old network which is a 2G/2.5G synchronous mobile communication network such as CDMA2000 communication network and a new network which is a 3G asynchronous mobile communication network such as a universal mobile telecommunications service (UMTS) network in a mobile communication network where the old network and the new network have coexisted the dual stack mobile communication system of the mobile communication network in which the old synchronous network and the new asynchronous network coexist forms a single node by combining same kind nodes of the old network and the new 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. As a result, the dual stack mobile communication system can smoothly interwork the old network and the new network in all the services which have been individually provided in the old network and the new network by overcoming mismatching of messages and subscriber profiles due to different protocols of the two networks, without introducing a gateway and a complicated message flow.

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.

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.

A display device including a display panel displaying an image; a light source unit supplying light to the display panel, and a light guiding unit including a light guiding section which has a light receiving surface positioned adjacent to the light source unit and a light emitting surface positioned opposite to the display panel and which guides light emitted from the light source unit to the display panel, a side wall section forming a reception space for receiving the display panel along the edges of the light guiding section, and a fixing section fixing the light guiding section to the display device.
摘要:
A non-aqueous electrolyte solution for a lithium secondary battery includes a lithium salt and an organic solvent and further includes a solvent having a fluoro group and a specific siloxane compound. A lithium secondary battery having the above non-aqueous electrolyte solution exhibits greatly improved capacity recovery characteristics after high temperature storage and also reduces side effects such as swelling.
摘要:
Disclosed are a novel thiazole-containing benzophenone derivative represented by formula 1, and an isomer thereof, a pharmaceutically acceptable salt thereof, a hydrate thereof and a solvate thereof, a pharmaceutical composition comprising the derivative, a use of the derivative as therapeutic agent and a method for preparing the derivative. The benzophenone thiazole derivatives inhibit formation of microtubules and eliminate actively proliferating cells of malignant tumors to control general cell proliferation. In formula 1, R, R1 and R2 are defined as above.
