  • Publication number: 20080190691
    Abstract: A shock absorbing lanyard is a one-piece webbing. The shock absorbing lanyard has a tubular-shaped high strength outer sheath and a high elongation member inside of the outer sheath. The outer sheath and the high elongation member are secured together at spaced apart connection locations and the high elongation member is generally not secured to the outer sheath between the connection locations. Heat treatment shrinks the length of the high elongation member. The outer sheath does not substantially shrink from the heat treatment relative to the high elongation member and gathers together in an accordion-like arrangement. A tensile load applied to the lanyard stretches the high elongation member and unfolds the gathered outer sheath. The high strength outer sheath supports the tensile load when completely unfolded while the high elongation member absorbs energy as it stretches or elongates.

  • Patent number: 7157843
    Abstract: A transfer film comprising a base film (11), a parting-agent layer (12), a protective film (13), and a metal film (14), the latter three being formed on the base film (11) in order, wherein the protective film (13) contains a softening agent such as a phosphate, an aliphatic monobasic acid ester, an aliphatic dibasic acid ester, or a dihydric alcohol ester. By using such a transfer film, a metal back layer is formed. Since the transfer layer of the transfer film has a surface resistivity of as high as 102–108 ?/, the surface resistivity of the formed metal back layer is high, and discharge is suppressed.
