Abstract: A multi-band receiver and a multi-band tuner are provided to reduce power consumption by using a single chip. Receiving units(210-230) form one-to-one correspondence with respective band signals to receive multi-band signals. A mixer unit(240) converts one of the multi-band signals into one of a baseband signal and an IF(Intermediate Frequency) signal. An LO(Local Oscillation) unit(250) provides a local oscillating signal corresponding to one band signal to the mixer unit. If the converted signal corresponds to a baseband signal, a reconfigurable bandpass filter unit(260) serves as an LPF(Los Pass Filter), and if a signal outputted from a selected receiving unit corresponds to an IF signal, the reconfigurable bandpass filter unit serves as a complex bandpass filter. An LFPGA(Low Frequency Programmable Gain Amplification) unit(270) amplifies a signal outputted from the reconfigurable bandpass filter unit.

Abstract: An apparatus for printing bead spacers at selected locations on an LCD substrate includes a cylindrical transfer roller and a printing plate having a plurality of semispherical recesses respectively located at positions corresponding to the selected locations of the spacers on the LCD substrate. A volume of an ink containing the spacers is loaded into each of the recesses, and the substrate is translated tangentially relative to the rotating transfer roller such that the volumes of ink are transferred onto the roller. A support plate having the LCD substrate mounted thereon is then translated tangentially relative to the roller such that the volumes of ink on the roller are transferred onto the surface of the LCD substrate at the selected locations. The apparatus enables the spacers to be printed onto the LCD substrate accurately and inexpensively, and prevents the spacers from being inadvertently printed in double layers.
