Abstract: Disclosed is a stylus pen combined with an antenna in a touch screen type-wireless terminal. The stylus pen has a built-in antenna and is detachably disposed in the touch screen type-wireless terminal, and the built-in antenna makes electrical connection with an antenna contact portion of an RF board of the terminal when the stylus pen is completely inserted in the terminal, such that the terminal has an improved antenna radiation characteristic and quality when compared with a terminal only having a fixed terminal antenna. The built-in antenna in the stylus pen may be a ?/4 dipole antenna or a ?/4 monopole antenna.

Abstract: Disclosed is a multinuclear transition metal half metallocene catalyst having a multinuclear half metallocene structure in which a transition metal of groups 3 to 10 on periodic table is connected to a cycloalkandienyl group or its derivative group on a side and also connected to phenol or phenolamine compound having a plurality of binding sites on another side. The metallocene catalyst is useful to produce syndiotatic styrene polymer having superior steroreguality, high melting point and broad molecular weight distribution with high activity together with a small amount of a cocatalyst. Further disclosed is a method for preparing styrene polymers using the same catalyst.

Abstract: A display apparatus including a panel to display images, a panel driver to control the panel to display the images, a scaler to process an input image signal according to a previously setup resolution, and to transmit the processed signal to the panel driver, an OSD (On Screen Display) controller to display an OSD message on the panel, and a control part to control the scaler to skip the input image signal in a regular interval and to transmit the processed signal to the panel driver, and to control the OSD controller to display the OSD message warning a frequency over range status, in response to a frequency of the input image signal exceeding a range of the previously setup resolution.

Abstract: A semiconductor wafer processing system having a multi-layered arrangement of wafer processing units included in a spinner to carry out photoresist coating and developing processes for the formation of micro patterns on semiconductor wafers, thereby enabling an easy increase in those processing units coping with an introduction of new processes without increasing the occupying space of the processing units, while being capable of achieving accurate wafer feeding and loading operations, and minimizing the consumption of a chemical solvent coated over wafers. The system includes groups of modules each being selected from first and second modules. The first module includes a plurality of bake units each having bake boxes arranged in a multi-layered fashion, the bake units being arranged adjacent to one another in the wafer feeding direction, and a spin unit, such as a spine coater or a spine developer, fixedly mounted on the bake units.
