    摘要: A system for compensating for mislanding of electron beams on the screen of a color cathode ray tube as a result of thermal expansion of a beam selecting structure in the tube comprises electromagnetic devices provided on the tube for producing respective magnetic fields by means of a current supplied thereto so as to change the paths of the electron beams passing through the beam selecting structure, and a circuit for supplying to the electromagnetic devices a current varying in response to a difference between the temperature of the beam selecting structure and the ambient temperature about the tube. The circuit for supplying a current to the electromagnetic devices may desirably include two temperature responsive elements, such as, variable resistors, respectively responding to variations in the temperature of the beam selecting structure and to variations in the ambient temperature about the tube, and preferably being connected in series across a voltage source with a connection point between the variable resistors being connected to the base electrode for controlling the current flowing through the collector-emitter path of the transistor to the electromagnetic devices.

    摘要: First, the present inventors assessed the effect of the compound represented by formula (III) below on Huh-7 cells infected with HBV, and demonstrated that the compound alone had an anti-HBV effect in vitro.Formula (III) Then, the present inventors revealed that the HBV replication-suppressing effect of PEG-IFN is enhanced in chimeric mice having a human liver infected with genotype C or A HBV when PEG-IFN is used in combination with the compound represented by formula (III) above. The present inventors also revealed that the HBV replication-suppressing effect of Entecavir is enhanced in chimeric mice having a human liver infected with genotype C HBV (wild-type and Entecavir-resistant strains) when Entecavir is used in combination with the compound represented by formula (III) above. In addition, the present inventors revealed that the compound represented by formula (III) above exerts the anti-HBV effect not only against wild-type HBV strains but also against Entecavir- and/or Lamivudine-resistant HBV strains.
