  • Publication number: 20080192020
    Abstract: A method of displaying information in a mobile terminal having a touch screen is provided. The method includes determining whether a touch input is generated by a touch screen, determining whether a touch area moves, calculating a movement direction of the touch area by extracting a value of the touch area movement, determining a current mode according to the calculated movement direction of the touch area, executing a function of the current mode corresponding to the extracted value of the touch area movement, and displaying, while executing the function of the current mode, at least one of a displacement value generated by executing the function of the current mode and a current mode icon indicating the current mode. Accordingly, when displaying information according to a touch input, changes of information may be displayed distinctively, and thereby user convenience may be improved.

  • Publication number: 20080093057
    Abstract: A cooling apparatus having an auxiliary chiller is provided. The apparatus can include a wafer chuck on which a wafer is mounted and in which a cooling cavity is formed. A main chiller having a main coolant reservoir can be spaced apart from the wafer chuck. The cooling cavity and the main coolant reservoir can be arranged in communication with each other through coolant passages. The coolant passages can include an auxiliary chiller detachably installed thereon, respectively. A method of cooling a wafer chuck or process chamber during a semiconductor device fabrication process is also provided. Using the method and apparatuses of this invention, fine temperature adjustments of the wafer chuck are possible.

  • Publication number: 20070008438
    Abstract: A tuner, a broadcast signal processing apparatus and method, which satisfy reception sensitivity of both terrestrial and cable televisions, when selecting a broadcast signal through a single conversion tuner, are provided. A tuner selects a broadcast signal of a selected channel. The tuner includes an input filter that filters a received broadcast signal into plural frequency bands based on a predetermined frequency band. An amplifier amplifies a second signal having an original phase induced by an output signal of the respective frequency bands, and a first signal having an opposite phase of the second signal, and outputs the signal induced by the amplified first and second signals as an amplification signal of the signal in the respective frequency bands. An inter-stage filter filters a frequency of the broadcast signal corresponding to the selected channel among the amplification signals output from the amplifier.
