    Abstract: The present invention relates to a method and an apparatus for driving image pick-up tubes in, particular, a color television camera or the like having more than one image pick-up tube and in particular to a method and an apparatus for driving image pick-up tubes in which the potentials of the cathode electrodes of the respective image pick-up tubes are set to the same common potential, the potential of the target electrode of at least one of the image pick-up tubes is set substantially to earth potential, target drive potentials are individually applied to the target electrodes of the other image pick-up tubes, and the target potential of each image pick-up tube is set to a value near the earth potential, so that a high S/N ratio is obtained. The driving appartatus can be miniaturized and easily driven. According to the invention, a capacitor, such as a chip capcitor or the like, with a low withstanding voltage can be used in a first-stage amplifier to amplify the video signal from the target electrode. This first-stage amplifier can be arranged near a signal output electrode of the target. Thus, the stray capacitance can be reduced.

    Abstract: In a discharge lamp lighting apparatus comprising a short arc type discharge lamp and a power supply unit, a relation of the natural frequency fe (Hz) of the electrodes, the ripple frequency fd (Hz) of the alternating current that is supplied to the discharge lamp, and the ripple power Pr (W) of the alternating current, satisfies a formula: Pr ≤  f e - f d  · ( - 0.13 × Vh Va + 3.0 ) , wherein the volume of the electrode head portion is represented as Vh and the volume of the segment of the electrode axis portion that projects into the arc tube is represented as Va. When the alternating current supplied to the discharge lamp satisfies the formula, it is possible to prevent or control damage in the electrode axis portion, since vibration produced in the electrodes during lighting of the discharge lamp is small even if the discharge lamp is lighted for a long time.

    Abstract: In a light source apparatus, an alternating current is supplied to a high pressure discharge lamp from a power supply apparatus to light the lamp. The arrangement state of the lamp is detected by a detection circuit. When the lamp is horizontally arranged, electric energy, whose flow direction is from one electrode of the lamp to the other electrode, is set to be approximately the same as electric energy, whose flow direction is from the other electrode to the one electrode. When the lamp is vertically arranged, while a cycle, which is the same as a polarity change cycle in the horizontal arrangement, is maintained, electric energy, which flows from an upper electrode to a lower electrode, is set to be smaller than electric energy, which flows from the lower electrode to the upper electrode.
