  • Patent number: 11296497
    Abstract: Provided is a surge protection circuit, which includes a bidirectional voltage suppressor; and a thyristor surge suppression unit connected in parallel with the bidirectional voltage suppressor. The first end of the bidirectional voltage suppressor is connected to the first end of the thyristor surge suppression unit, and the second end of the bidirectional voltage suppressor is connected to the second end of the thyristor surge suppression unit. The breakover voltage or the breakdown voltage in the direction from the first end to the second end of the thyristor surge suppression unit is greater than the clamping voltage in the direction from the first end to the second end of the bidirectional voltage suppressor. The breakover voltage in the direction from the second end to the first end of the thyristor surge suppression unit is less than the clamping voltage in the direction from the second end to the first end of the bidirectional voltage suppressor.

  • Patent number: 8968727
    Abstract: The present invention provides a telomerase activity inhibiting polypeptide. The expression of the polypeptide in tumor cells can inhibit significantly tumor cell telomerase activity, tumor cell growth, and lead to the death of such cells. The present invention further provides a preparation method for the polypeptide and an application thereof in targeted treatments of tumors.
