摘要： Photoreceptors for use with, for example, pulsed lasers, in particular semiconductor lasors, must be durable, fast, thermally stable and sensitive to wavelengths of usually greater than 780 mm. The present invention provides photoreceptors having a photosensitive layer containing certain azo compounds which are good carrier generators. These azo compounds can be used, preferably with a good carrier transferring material, to produce photoreceptors having the above characteristics.

摘要： A spool for photographic film (1) wherein a film-insertion slit (5) is provided between two flanges (4,4') of a winding shaft (3) for attaching the end of the film (1) and winding the film (1) thereon, and two engagement pawls (9, 10) are provided separately from each other in the axial direction of the winding shaft (3), while a comparatively narrow film-presser rib (8) is provided in part of the other wall facing the first wall between the two engagement pawls (9, 10). Each of the engagement pawls (9, 10) has an inclined part ascending toward the other wall gradually in the direction of film-insertion, and a horizontal pawl part continuing from the inclined part. Each of the horizontal pawl parts is shaped in accordance with part of a virtually oval engagement hole (2, 2') formed in the end of the film (1), and has a film engagement section inclined toward the first wall and toward the film-insertion side of the slit (5) and is separated a distance from the first wall slightly larger than the thickness of the film (1). The film-presser rib (8) has an inclined surface descending toward the first wall gradually in the direction of film-insertion, and a horizontal surface continuing from the inclined surface.

摘要： A radiographic image forming process comprises treating a negative type-silver halide photegraphic light-sensitive material comprising a support bearing on each side thereof a constituent layer containing,
a) light-sensitive silver halide particles, b) metallic salt particles whose surfaces are retarded to be soluble by a dissolution retarder while said metallic salt particles themselves are more readily soluble then said light-sensitive silver halide particles, and which is non-light-sensitive, and c) physical development nuclei, with a processing solution after exposing imagewise to radiation rays in combination with a fluorescent intensifying screen. Problems arising from cross-over phenomena, i.e. images on one side produced by light transmission through the support, can be avoided by incorporating within the constituent layers;
d) at least one water-soluble dye whose maximum absorption in an aqueous solution is from 400 to 600 nm, or a compound comprising said water-soluble dye coupled to a non-diffusive mordant, and employing in the processing solution: i) at least one reducing agent, and ii) at least one substance capable of dissolving the undermentioned metallic salt particles.-
