An exhaust heat recovery apparatus is installed proximate an engine and at a front side of a warm-up catalytic converter in an exhaust system, where the exhaust system includes an exhaust line connected with the engine, and the warm-up catalytic converter is installed at the exhaust line. The exhaust heat recovery apparatus includes a bellows unit which is of a dual-pipe type and exchanges heat between exhaust gas emitted through the exhaust line and coolant circulating from a cooling system to the engine.

Exhaust heat recovery apparatus

A shift register includes a plurality of scan stages to output scan pulses to a plurality of gate lines, a first dummy stage to output a first dummy scan pulse to a first of the plurality of scan stages, and a second dummy stage to output a second dummy scan pulse to a last of the plurality of scan stages.

Shift register

Disclosed is a dual shift register that includes a first shift register configured to include a plurality of stages which sequentially output scan pulses using at least two clock signals with sequential and circular phases, and a second shift register configured to a plurality of stages which form pair with the respective stages of the first shift register and sequentially output the scan pulses using at least two clock signals. Each stage includes: a scan direction controller configured to respond to the scan pulses from previous and next stages and to selectively output forward and reverse direction voltages with opposite electric potentials to each other; and an output portion configured to respond to the output signal of the scan direction controller, to generate two sequential scan pulses using two of the at least two clock signals, and to distribute the sequential scan pulses to the previous and next stages.

Dual shift register

A color filter substrate includes a first color filter layer on a substrate, and a second color filter layer on the substrate, the first color filter layer having a thickness different from a thickness of the second color filter layer.

Color filter substrate and method of fabricating the same

An apparatus and method of driving a flat panel display device is disclosed, to prevent the appearance of afterimages on the flat panel display, the apparatus comprising an image displaying unit which includes a plurality of pixel cells in regions defined by a plurality of gate and data lines on a display panel; and an means formed on the display panel to be connected with the respective gate lines, wherein the means carries out an inspection or discharges electric charges from the image displaying unit when a system power is turned-off, wherein the electric charges are discharged from the image displaying unit by detecting the turning-off point of system power so as to remove the afterimage from the image displaying unit.
