Abstract: A desalinization apparatus includes a section for heating up input saline water using the heat released in subsequent water vapor condensation. A solar heater may be used to raise the saline water to a proper evaporation temperature, and a carrier gas is used as a vehicle for transporting water vapor from evaporation to condensation sections.

Abstract: An electric recording system is a novel recording system using an electric heat recording sheet comprising an electric conductive layer and an electric resistant layer, and heating the electric resistant layer by feeding a signal current to the recording sheet by contacting an electrode needle with the recording sheet and recording symbols or figures on the recording medium (e.g., commercial thermo-sensitive paper) through the electric conductive layer.In the other embodiment of the electric heat recording sheet, an electric resistant layer is formed on one surface of an electric conductive layer and an ink layer is formed on the rear surface of the electric conductive layer whereby heat is transferred from the electric resistant layer to print shape image by printing a part of the ink layer on the recording medium, such as a regular paper.

Abstract: A thin metallic film is superposed on a light transmitting, dielectric substrate through a lattice-shaped, electric conductor disposed on the substrate to maintain it spaced away from the latter. The film is provided on the exposed surface with a lattice-shaped electric rib and fixed at the periphery to the substrate by a binder.
