  • Publication number: 20080018314
    Abstract: A DC-DC converter capable of operating in a pulse-skipping mode for transforming power provided by a power generator for a load circuit includes a driving circuit for generating a gate driving signal according to a feedback signal and a pulse-skipping-mode control signal, a converter circuit for transforming power provided by the power generator for the load circuit according to the gate driving signal, a feedback circuit for generating the feedback signal for the driving circuit according to a feedback voltage of the load circuit, and a pulse-skipping-mode control circuit for generating the pulse-skipping-mode control signal and adjusting on-time of the generated pulse-skipping-mode control signal according to voltages outputted from the power generator and the converter circuit, so as to adjust voltage outputted from the converter circuit via the driving circuit.

  • Patent number: 5932219
    Abstract: The entire genome of the hepatitis D virus has been shown to be a circular single-stranded RNA of 1679 bases. Several open reading frames in both the genomic and complementary strands indicate possible protein products. The products encoded in one open reading frame, ORF5, are identified as viral polypeptides p24.sup..delta. and p27.sup..delta., of which the nuclear .delta. antigens in HDV infected liver is comprised. These products, as well as others encoded in ORFs 1, 2, 6, and 7 are produced in recombinant expression systems. The ORF5 products, in particular, are useful for HDV diagnosis and vaccines.

  • Patent number: 5750350
    Abstract: The entire genome of the hepatitis D virus has been shown to be a circular single-stranded RNA Of 1679 bases. Several open reading frames in both the genomic and complementary strands indicate possible protein products. The products encoded in one open reading frame, ORF5, are identified as viral polypeptides p24.sup..delta. and p27.sup..delta. of which the nuclear .delta. antigens in HDV infected liver is comprised. These products, as well as others encoded in ORFs 1, 2, 6, and 7 are produced in recombinant expression systems. The ORF5 products, in particular, are useful for HDV diagnosis and vaccines.

  • Patent number: 5378814
    Abstract: The entire genome of the hepatitis D virus has been shown to be a circular single-stranded RNA of 1679 bases. Several open reading frames in both the genomic and complementary strands indicate possible protein products. The products encoded in one open reading frame. ORF5, are identified as vital polypeptides p24.sup..delta. and p27.sup..delta., of which the nuclear .delta. antigens in HDV infected liver is comprised. These products, as well as others encoded in ORFs 1, 2, 6, and 7 are produced in recombinant expression systems. The ORF5 products, in particular, are useful for HDV diagnosis and vaccines.
