Abstract: Described is a plasma switched organic photoluminescent display including lower and upper plates. The lower plate includes a transparent rear substrate, a plurality of address electrodes arranged in a first direction on the transparent rear substrate like stripes in parallel each other, a white back dielectric layer on the transparent rear substrate including the address electrodes, a plurality of barrier ribs arranged in parallel each other on the white back dielectric layer between the address electrodes in the first direction, respectively, a plurality of organic photoluminescent layers on the exposed white back dielectric layer between the barrier ribs, respectively, and a plurality of photoluminescent-layer-protecting layers on the organic photoluminescent layers, respectively.

Abstract: Described is a plasma switched organic electroluminescent display, which includes an electroluminescent part including a cathode layer, an electroluminescent layer on the cathode layer, and an anode layer on the electroluminescent layer, a first power supply unit connected electrically to the anode layer and disconnected electrically to the cathode layer so as to supply the electroluminescent layer with a first power, a plasma generating part generating a plasma wherein the plasma becomes contacted with the cathode layer, and a second power supply unit generating the plasma by supplying the plasma generating part with a second power, wherein the cathode layer is connected electrically to the first power supply unit through the plasma, thereby enabling to emit light by organic electroluminescence as well as drive the display by a low driving voltage using a plasma discharge as a switch.

Abstract: A transmission apparatus with reduced current consumption for a mobile terminal is disclosed. The transmission apparatus includes an automatic gain control (AGC) amplifier for AGC-amplifying an input baseband signal; an attenuator for attenuating an output signal of the AGC amplifier; a multiplier for multiplying an output signal of the attenuator by a carrier frequency signal to convert the signal into a radio frequency (RF) signal; a first filter for filtering an output signal of the multiplier; a drive amplifier for amplifying an output signal of the first filter; a second filter for filtering an output signal of the drive amplifier; a power amplifier for amplifying an output signal of the second filter; and an antenna. When output power of the mobile terminal is lower than predetermined maximum output power of the AGC amplifier, the output signal of the AGC amplifier is transmitted through the multiplier, the first filter and the antenna.

Abstract: Polytetramethylene ether glycols (PTMEG) are fractionated with liquid propane in an extractor under high pressure. Fractions are separated by altering the extraction pressure, which alters the solvent power of the propane. The polydispersities of all extracted PTMEG fractions are generally below 1.3. The addition of a cosolvent, preferably tetrahydrofuran, can effectively lower the initial extraction pressure and increase the efficiency of the extraction.
