A method for preparing a photothermographic material comprising an organic silver salt is disclosed, comprising a step of treating the organic silver salt under a gas atmosphere containing an inert gas having a volume fraction of not less than 85% or under a gas atmosphere containing oxygen gas having a volume fraction of not more than 15%. Packaging the photothermographic material under the inert gas atmosphere is also disclosed.

Preparation method of photothermographic material

An anti-static-treated film material having an electro-conductive layer is disclosed. The film material contains at least one selected from conductive particles and semi-conductive particles at an amount between 1 and 50 vol. % with respect to said electro-conductive layer and polymer particles having an average particle diameter of 0.01 to 5 .mu.m, and the absolute value of impedance of said film material under frequency at 20 Hz is between 4.times.10.sup.5 and 1.times.10.sup.20 .OMEGA.. The film material is suitably used as a support of asilver halide light sensitive material.

Plastic film having an improved anti-static property

A silver halide photographic light sensitive material is disclosed, comprising a support having on the support a silver halide emulsion layer comprising silver halide grains, wherein at least 50% of the total grain projected area is accounted for by tabular grains having an aspect ratio of 2 or more, at least one of subbing layers provided on both sides of the support comprising colloidal tin oxide sol.

Silver halide photographic light sensitive material

A silver halide black and white photographic light-sensitive material is disclosed, comprising a support having thereon two silver halide emulsion layers, wherein a silver halide emulsion layer provided further from the support contains tabular silver halide grains having an aspect ratio of not less than 3, another silver halide emulsion layer containing silver halide grains having an aspect ratio of not more than 2.5; both silver halide grain emulsions are each spectrally sensitized by adding thereto a spectral-sensitizing dye in the form of a dispersion of solid particles dispersed in an aqueous medium.

Silver halide photographic light-sensitive material

Apparatus for inspecting the electrical stimulation of a patients' heart. The apparatus includes a stimulation device in which electrical stimulating wave is generated by an electrical stimulation wave generating device for effecting pacing of a patients' heart in accordance with an externally set stimulation pattern impressed upon the wave and applied to the heart through a catheter, wherein intracardiac electrocardiogram signals are induced, amplified, and recorded on a recorder which is annexed to the stimulation device. The recorder is designed to commence the recording operation in response to a recording start signal in advance of the generation of the final electrical stimulation wave, and to stop the recording operation in response to the intracardiac electrocardiogram signal generated for the first time after the generation of the final electrical stimulation wave. During the operation, waveforms of the final stimulation signal and the intracardiac electrocardiogram signal are recorded and the characters representing the stimulation pattern are printed.
