A mono- or multi- layer recording member, suitable for recording using e.g., a laser, comprising a support having a recording layer thereon wherein the recording layer contains (a) a metal selected from the group consisting of Sn, Bi and In and (b) a halide capable of being thermally or photo-chemically activated by high energy density light irradiation and which thereby can promote a thermally initiated phase or structure change of the metal (a).

A recording method wherein electrostatic atomization of a liquid is applied to the phenomenon that when a coloring material solution holding member is partly immersed in a solution of coloring material, the solution juts up from the surface thereof in accordance with the affinity of the material of the coloring material solution holding member with the solution. The coloring material solution holding member is formed of an insulating material and has strips of a conductive material arranged in s...

A recording device for reproducing image information onto a recording medium as a visible image, the device including an original mounting table for supporting original containing information to be recorded, an original feeding device to feed the original into the mounting table an image original detector to detect arrival of the original at a predetermined position on the mounting table, an image recording device to record the image information in the original onto a recording sheet, instructio...

Magnetic recording media including permanent structures of aligned acicular particles have been proposed as a means of identifying and authenticating a medium. A structure which has an improved remanence difference signal is described. A method of making and examining such a structure is described. Arrangements of such media and record/read-out apparatus by which information can be recorded and read-out without interference from the structural remanence differences are described. The use of the ...

A recording material comprising a support having thereon a layer contaning (i) at least one metal and (ii) a layer containing one or more metal sulfides other than GeS, metal fluorides or metal oxides. A mono-layer mixture of (i) and (ii) may also be used.

A tape recording apparatus comprises a first mechanism capable of varying, between a maximum and a minimum length, a tape travel path extending between a recording and reproducing head and a tape take-up roll. A second mechanism controls the first mechanism so that the length of the tape travel path becomes the maximum length at the time of ordinary recording and at the time of editing. The length of the tape travel path becomes the minimum length at the time of a pause mode prior to the editing...

A recording system for a HUD comprises a prism optical system for combining light from the symbol generator and from the scene as viewed by an observer light so that the combined image emitted from the system has the correct orientation, and a camera for mounting on the side of the HUD

A recording stethoscope includes a transducer assembly for converting variations in atmospheric or air pressure within the stethoscope into analog electrical signals. The transducer assembly includes a transducer responsive to variations in atmospheric pressure mounted with a housing that includes at least two sections that support the transducer by engaging and clamping the periphery thereof. The variations in atmospheric pressure are intensified by providing a conical chamber in front of the t...

A recording device for making a permanent record of a manually entered variables versus time includes a single toothed lever driven by an electric motor in an orbital path for intermittent engagement with an internal ring gear on a chart carrying platen. Manually movable marking means for entering the variables are carried by a transparent cover hingedly mounted over the chart.

A recording apparatus of the non-impact type comprises a thermal head having a plurality of islands generally disposed in a common plane which are thermally independent and can heat separately and selectively. The apparatus employs a print member composed of a heat-resistant back-up layer and a thin film of an adhesive resin of low melting point disposed over the back-up layer, and also employs a web of recording paper free of any thermosensitive material. When the thermal head and the recording...
