A system having a mother board with a PCI controller and an AGP connector formed thereon is provided. It is assumed that a signal having a rising edge and a step waveform which lags the rising edge by a fixed time interval and a signal having a step waveform and a falling edge which lags the step waveform by the fixed time interval are entered as an input signal to a cell. The alloy exhibits a unique combination of strength, ductility, density, and opacity suitable for use as wire, tube, sheet, or foil products. The reflective area of the first reflective layer has a cholesteric liquid crystalline structure.
