Abstract: A data transmission and receiving system in a mobile communication system is provided. The system includes a first data providing server which contains detailed data and to which a user gets an access by inputting a predetermined code or number through a mobile communication terminal; a second data providing server which contains a simplified data including the predetermined code or number information associated with the detailed data; and a mobile communication terminal including a user interface that allows a user access to the second data providing server to search the simplified data to access the detailed data in the first data providing server, wherein the user interface includes a search section allowing a user to input certain keyword data to search simplified data associated with the keyword data from the second data providing server and a data display section for displaying the simplified data searched by the searching section.

Abstract: The present invention relates to a carrier cup of a planet carrier that improves strength thereof and reduces noise occurring in an automatic transmission by changing an interior circumferential shape of a leg. The carrier cup of a planet carrier according to an exemplary embodiment of the present invention at which pinion gears are mounted such that the pinion gears are rotatably supported thereby may include a carrier plate provided with a carrier hole for mounting a carrier shaft and a plurality of pinion holes for mounting the pinion gears, and a plurality of legs extending perpendicularly from one side surface of the carrier plate, wherein radial thickness of the leg is changed along a circumferential direction thereof.

Abstract: A hydraulic control system includes a key detector that detects whether an ignition key is in an on state, a control portion that outputs different control signals according to whether the engine is on if the key is on, and a valve, such as a solenoid valve, that controls gear shifts according to the control signals from the control portion. A hydraulic control method includes determining whether an ignition key is on; determining whether an engine is on or off if the key is on; and controlling a valve, such as a solenoid valve, that controls gear shifts, differently depending on whether the engine is on or off, such as by applying different duty values to the valve. A low duty value may be applied to the valve when the engine is off, and a higher duty value may be applied to the valve when the engine is on.
