  • Patent number: 5863232
    Abstract: A method for making a micro tip of an FED device includes the steps converting impurity layer regions into porous semiconductor layer regions by performing an anodic reaction using an HF aqueous solution as an electrolytic solution, oxidizing the porous silicon layer regions, and removing the oxidation layer by etching with HF aqueous solution. The shape of the fabricated micro tip is regular and precise, since the size and height of the micro tip are easily controlled. Hence, the size and direction of an electron beam emitted from the micro tip is regular, and a reliability of the FED device is enhanced.

  • Patent number: 5849742
    Abstract: The present invention relates to organic molecules capable of modulating tyrosine kinase signal transduction and particularly KDR/FLK-1 receptor signal transduction in order to regulate and/or modulate vasculogenesis and angiogenesis. The invention is based, in part, on the demonstration that KDR/FLK-1 tyrosine kinase receptor expression is associated with endothelial cells and the identification of vascular endothelial growth factor (VEGF) as the high affinity ligand of FLK-1. These results indicate a major role for KDR/FLX-1 in the signaling system during vasculogenesis and angiogenesis. Engineering of host cells that express FLK-1 and the uses of expressed FLK-1 to evaluate and screen for drugs and analogs of VEGF involved in FLK-1 modulation by either agonist or antagonist activities is also described.
