Abstract: A novel photographic silver halide emulsion is disclosed, which is useful in a color photographic silver halide material to provide improvements in image quality, storage stability and pressure resistance. The photographic silver halide emulsion comprises silver halide twinned crystal grains each having a ratio of grain diameter to grain thickness of 5 or less which amount to 50% or more by projection area of total grains, wherein X-ray diffraction pattern of the twinned crystal grains with Cu-K.alpha. ray as a radiation source has a (420) diffraction signal having a single peak; and the width of the peak at a height of 0.13 times the maximum peak height, based on the signal intensity, is 1.5 degree or less in a diffraction angle, 2.theta..

Abstract: A door impact beam, which is arranged in a door panel structure, comprises a beam body, arranged along the longitudinal direction of a door, and attachment portions arranged individually at two opposite ends of the beam body. The beam body is formed of a heat-treated hollow member steel. The attachment portions are individually fixed to the door panel structure. The beam body has a section in the form of a quadrilateral frame having four sides and four rounded corners. The outer radius of curvature R of each of the four corners is adjusted to a value such that the radius R falls within a range of 1.5 t.ltoreq.R.ltoreq.3.5 t, where t is the wall thickness of the hollow member.
