  • Patent number: 10975550
    Abstract: In a vibration suppression control OFF state, a signal pressure supply control valve stops supplying a first signal pressure, a pressure-regulating valve is in first position where a supply/discharge port connects to a pump port, and an open/close signal pressure is not supplied to an open/close control valve, so an open/close valve is closed. When the OFF state switches to ON state, the signal pressure supply control valve allows supplying the first signal pressure, and the pressure-regulating valve is in second position where the supply/discharge port connects to a tank port, so the pressure of a pressure accumulator decreases. In the ON state, when the pressure of the pressure accumulator is equal to pressure of a pressure chamber, the pressure-regulating valve is in third position where the supply/discharge port is blocked, and the open/close signal pressure is supplied to the open/close control valve, so the open/close valve is opened.

  • Patent number: 9474793
    Abstract: The present invention provides methods for lowering a viral load of a virus resistant to an antiviral drug by inducing cytotoxic T lymphocytes (CTL) to recognize a predetermined mutated epitope within a viral protein of the drug-resistant virus. CTLs are induced by immunizing a host with a peptide comprising the predetermined mutation. The immunostimulating peptide may be further improved by epitope-enhancement for inducing specific CTLs. The antiviral protection against drug-resistant virus shown by compositions of the present invention and mediated by human HLA-restricted CTL has not been previously achieved.
