Abstract:
Disclosed herein are a printed circuit board and a method of manufacturing the same, which can achieve reliable heat resistance because heat radiation characteristics are improved, and processing costs of which are reduced because processing times are shortened.
Abstract:
A method of manufacturing an optical component embedded printed circuit board, the method including: stacking a first insulation layer on one side of a metal core; embedding an optical component in a cavity formed in the metal core; stacking a second insulation layer of a transparent material on the other side of the metal core; and forming a circuit pattern on the first insulation layer, the circuit pattern electrically connected with the optical component.
Abstract:
This invention is related to new ethylaziridine derivatives of formula (I) and their preparation. The compounds are useful synthetic intermediates for the synthesis of HIV protease inhibitors and oligopeptide mimetics.
Abstract:
Secretion signal peptides of inulinases derived from Kluyveromyces marxianus, which makes a heterologous protein produced in a yeast cell be secreted almost completely into the extracellular medium; nucleotide sequences encoding said secretion signal peptides; expression and secretion vectors comprising nucleotide sequences encoding said secretion signal peptides; recombinant yeast cells transformed with said expression and secretion vectors; and a process for producing heterologous proteins by culturing said recombinant yeast cells.
