Abstract: An elliptical photo-acoustic spectrometer chamber design will result in a larger intensity signal at the pick-up microphone and allow high frequency light modulation. This makes the spectrometer have a lower limit of detection threshold, and will increase the signal to noise ratio in general for the instrument, resulting in a more sensitive instrument allowing more precise measurements.

Abstract: A flat-panel display is fabricated by a process in which a spacer (24) having a rough face (54 or 56) is positioned between a pair of plate structure (20 and 22). When electrons strike the spacer, the roughness in the spacer's face causes the number of secondary electrons that escape the spacer to be reduced, thereby alleviating positive charge buildup on the spacer. As a result, the image produced by the display is improved. The spacer facial roughness can be achieved in various ways such as providing suitable depressions (60, 62, 64, 66, 70, 74, or 80) or/and protuberances (82, 84, 88, and 92) along the spacer's face.
