摘要： A first electronic apparatus is provided with a relay energized at a low voltage, the relay having a contact connected in parallel with a power supply switch for the first electronic apparatus. The first electronic apparatus is further provided with a signal generator circuit for energizing a second electronic apparatus. An output signal generated from a third signal generator circuit of a third electronic apparatus is applied to the coil of the relay of the first electronic apparatus thereby to operatively interlock the first electronic apparatus with the third electronic apparatus. Alternatively, an output signal generated from a signal generator circuit of the first electronic apparatus is applied to a relay of the second electronic apparatus having a contact through which power is supplied to the second electronic apparatus, thereby operatively interlocking the second electronic apparatus with the first electronic apparatus.

摘要： A vertical deflection circuit of the negative feedback type wherein a feedback signal, being generated at a terminal of a deflection current detector resistance connected in series with a vertical deflection yoke, is connected to negative feedback amplifier which guides the output of a sawtooth wave generating circuit through a third order distortion wave generating circuit. The third order distortion wave generating circuit imparts third order distortion of positive polarity to said feedback signals, so that third order distortion of negative polarity is imparted to the current of said deflection yoke, and whereby the third order distortion is compensated and extinguished on the CRT display.
