摘要:
A light-sensitive silver halide emulsion is disclosed, which comprises light-sensitive silver halide grains in a binder, wherein tabular grains having a diameter of at least 0.15 .mu.m account for at least 70% of the total projected area of said silver halide grains, said tubular grains have a mean aspect ratio of not more than 8.0, and at least 50% (by number) of all of said tabular grains are tabular grains in which the ratio (b/a) of the thickness (b) of said tabular grain to the longest spacing (a) between two or more parallel twinning planes of said tabular grain is at least 5. A color photographic material using the light-sensitive silver halide emulsion for at least one of the silver halide emulsion layers other than the outermost silver halide emulsion layer is also disclosed.
摘要:
A photosensitive silver halide emulsion whose grain diameter/grain thickness ratio is 5 or more. The grains of the emulsion each comprises a core that consists substantially of silver bromoiodide containing from 4 to 20 mol % of silver iodide, and a shell that covers the core and consists substantially of silver bromide or silver bromoiodide containing 3 mol % or less of silver iodide, and the relative standard deviation of the silver iodide content among the grains of the emulsion is 20% or less.

摘要:
A pierce nut having a central pilot, a cylindrical flange portion surrounding the pilot and a groove in the flange portion having at least one inclined side wall and a bottom wall having a convex annular protuberance preferably comprising spaced arcuate protuberances extending around the pilot which deforms panel metal beneath the inclined side wall and providing anti-rotation means when the nut is attached to a metal panel. The outer groove side wall includes radial notches or grooves which receive panel metal to provide anti-torque means. The improved die button includes an annular lip having an inside piercing edge spaced from the end to pierce a smaller slug and an annular convex fillet which deforms more panel metal into the nut groove to form a secure mechanical interlock between the nut and panel.
