  • Growth factor anchoring type bone graft material, method for producing growth factor anchoring type bone graft material, kit for producing growth factor anchoring type bone graft material, and method for forming bone
    Patent number: 9248164
    Abstract: Provided is a growth factor anchoring type bone graft material, wherein a bone graft substrate exposing at least a collagen fiber is bound to a collagen-binding-site-containing growth factor which contains a growth factor receptor agonist peptide and a collagen-binding peptide. The same can be produced by mixing a bone graft substrate and a collagen-binding-site-containing growth factor which contains a growth factor receptor agonist peptide and a collagen-binding peptide, and is also superior in osteogenic ability.

  • Method for forming cover layer over wire joint
    Patent number: 4822434
    Abstract: The invention provides an improved method for forming a cover layer over a joint of electrical wires. Portions of insulation layers of wires to be joined are stripped and the bared conductors of the wires assembled in a desired configuration to form a joint. The joint is placed in a transparent mold and the mold is filled with a photosetting resin. Radiation of an appropriate wavelength is then passed through the mold to harden the resin.
