Abstract: A photochromic display and storage element having a relatively high photochromic efficiency at temperatures above room temperature and a relatively low photochromic efficiency at room temperature consists of a substituted thioindigo dye dissolved in a heat-cured epoxy resin having a glass transition temperature of between above room temperature and 100*C. Information is placed on the element by heating it to or above the glass transition temperature and shining light of a first wavelength (write light) on the element. The image is stored by cooling the element to room temperature. In order to read the image, light of a second wavelength (read light) is passed through the element at room temperature. The image is erased with light of this second wavelength by first heating the element to or above the glass transition temperature.

Abstract: The recording element comprises an electrically conductive substrate and a layer of a photoconductive, pyroelectric compound on the substrate. The layer comprises one or more wafers of the pyroelectric compound, each wafer being similarly oriented on the substrate so that its polar c-axis is transverse to the opposite large surfaces of the layer. The novel electrophotographic recording element is charged by merely changing the temperature of the layer a few degrees.

Abstract: A high power, solid state, coaxial microwave switch wherein a plurality of diodes are mounted between the inner and outer conductors and a plurality of conductive rods are connected between the inner and outer conductors. The rods are selected such that the inductance of the rods and the capacitance of the diodes when reversed biased provide a resonant circuit at a predetermined frequency, whereby microwave energy incident upon the reversed biased diodes passes through the switch with little attenuation. When forward biased, the diodes provide a low impedance, whereby microwave energy incident thereon is substantially reflected.
