  • 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.

  • Publication number: 20150203830
    Abstract: The present invention provides peptides and proteins for use in second generation HIV vaccines and as diagnostic tools in the treatment and control of HIV infection. The antiviral protection shown by compositions of the present invention has not been previously achieved with an HLA epitope-enhanced vaccine. These findings define a critical balance between MHC affinity and receptor crossreactivity required for effective epitope enhancement and also demonstrate construction and efficacy of such a component of a new generation vaccine.

  • Patent number: 8474971
    Abstract: A transport apparatus transports a recording medium fed from a feeding roll and wound up onto a take-up roll. A transport roller is arranged in a path between the feeding roll and the take-up roll. A first tension bar is arranged in a path between the transport roller and the take-up roll to apply tension to the recording medium in a first direction different from a transport direction of the recording medium. A second tension bar is arranged in a path between the first tension bar and the take-up roll to apply tension to the recording medium in a second direction different from the first direction. The first and second tension bars apply tension to the recording medium in the first and second directions so that the recording medium is tightened by the first and second tension bars and the tightened recording medium is wound up onto the take-up roll.

  • Publication number: 20110242245
    Abstract: Provided are a transport apparatus and a printer capable of transporting a recording medium with no slack even when a disturbance or the like has occurred, and maintaining horizontal attitudes of tension bars, as well as easy loading of the recording medium and easy placing of the tension bars after the recording medium is loaded. The tension bars apply tensions in a transport direction and in a direction perpendicular to the transport direction to the recording medium in a roll shape that is fed from a feeding roll and wound up onto a take-up roll. Accordingly, predetermined tensions are applied to the recording medium. Before the recording medium is loaded, the tension bars are supported at retrieval positions, respectively, and the respective tension bars are placed at predetermined positions after the recording medium is loaded, with the result that the recording medium may be loaded with ease.
