Abstract: Disclosed is an exercise-data management system, which comprises a wristband 8 including an IC chip 7 recording therein unique information for authenticating a participant, a studio gate 3 set up in a studio and adapted to wirelessly receive and read the unique information recorded in the IC chip, and an exercise-data management server apparatus 4. The studio gate 3 is operable, when the unique information is read, to transmit information indicating the read to the exercise-data management server apparatus 4.

Abstract: A high-frequency horizontal deflection/high-voltage generation apparatus capable of setting inductance of a deflecting yoke without being affected by a collector voltage of a horizontal switching transistor and suppressing power loss while increasing a deflecting pulse voltage so that amplitude adjustment and side-pin correction can be effectuated without incurring any appreciable power loss. A voltage which is higher than the collector voltage V.sub.CP of the switching transistor is applied to the deflecting yoke. A resonant circuit is provided for applying to the deflecting yoke a voltage pulse of positive polarity and that of negative polarity, i.e., the voltage pulses bearing opposite phase relation to each other, for increasing equivalently the voltage applied across the deflecting yoke. The switching waveform outputted from the resonant circuit is synchronized with a switching operation of a high-speed switching element driven by a voltage induced in a winding of the deflecting transformer.
