A DA conversion circuit in accordance with the present invention, which is provided with a switch swD, allows a writing operation of a voltage to be performed at a higher speed by first applying a first voltage, which is supplied without passing through a resistor element, to an output line and then applying a second voltage, which is supplied via the resistor element, to the output line. The EASLM is arranged in use to be driven successively by a set of sub-holograms which together correspond to a holographic image. A motion input is recognized at a second screen of the multi-screen system, and the motion input is recognized while the hold input remains held in place. The process reduces the energy by reducing the endothermic properties of intermediate reformed process streams. More preferably, a transition space is provided between the outlet at the end of the nozzle and the revolving flow forming device, and the outlet at the end of the nozzle is made small in diameter. A lift assembly is attached to the tube and the panel.
