摘要： A horizontal deflection circuit which including a horizontal output transistor; a damper diode connected in parallel with the horizontal output transistor; a resonant capacitor connected in parallel with the damper diode; a horizontal deflection coil connected in parallel with the horizontal output transistor; and a series resonant circuit connected in parallel with the resonant capacitor. The series resonant circuit is constituted by a series connection of a capacitor and an inductor to perform composite resonance in cooperation with the resonant capacitor. The capacitor and the inductor of the series resonant circuit are designed to have a tertiary resonant frequency. The composite resonance by means of the series resonant circuit and the resonant capacitor enables the top of the flyback pulse to be flattened, so that the waveform of the flyback pulse becomes near the form of rectangular wave. Accordingly, a horizontal deflection circuit having higher retracing capacity can be provided through the same horizontal output transistor as generally used in the prior art.

摘要： A discriminator apparatus for a television multivoice system comprises a mixer for mixing a program identifying signal with a reference signal thereby to produce a differential beat signal. A reference signal generator includes a signal source of an original frequency, and a frequency converter for converting the original frequency to the reference frequency which is close to the frequency of the program identifying signal and so selected that the frequency of the differential beat signal is lower than the lowest audible frequency. A low-pass filter is employed for extracting the differential beat signal. Need for expensive mechanical filters of a narrow fractional bandwidth is thereby eliminated.

摘要： Red, blue and green color difference signals are supplied to the bases of first, second and third transistors amplifying the tri-color signals of red, blue and green, and a luminance signal is introduced to the emitter of each transistor through a parallel circuit of two resistors. One of the resistors in each parallel circuit is connected through a switch. The switches are associatively operated so that the on-off operation of the switch connected to the emitter of the first transistor is opposite to that of the switches connected to the emitters of the second and the third transistor. By operating the switches, the amplification degree of the first transistor is increased and simultaneously the amplification degrees of the second and third transistors are decreased, and therefore an image with red emphasized can be obtained with no change in luminance.
