    Notes: Abstract A dc photovoltaic effect has been observed in thin films of Pb(Zr, Ti)O3 evaporated on stainless steel, in the absence of applied field. The spectral photovoltaic response of the film has a peak sensitivity around 4000 Å. The photovoltage exists only below the Curie temperature. The film device becomes semiconductive under illumination.

    Notes: Abstract Thermal radiation calorimetry has been applied to measure the thermal diffusivity of a solid specimen, along with simultaneous measurements of specific heat capacity and thermal conductivity. In this calorimeter, a disk-shaped solid specimen whose surfaces are blackened is heated and cooled slowly on one face by irradiation in a vacuum chamber. A quasi-steady-state approximation in which a linear temperature gradient within the specimen was assumed is considered in the analysis. The validity of this approximation was confirmed by the results of computer simulation based on the control-volume method. Measurements of Pyroceram 9606 and Pyrex 7740 by use of thermocouples in the temperature range between 250 and 400°C gave values consistent with those obtained by previous authors, within experimental error, for all three thermophysical properties.
