Title: Video signal scramble system
Inventor: UEHARA SHOJI
IPC: H04N7/171
Filed: 1989-03-31
Abstract: PURPOSE:To eliminate adverse effect onto an audio signal and a video signal and to simplify the constitution of the system by utilizing only a sinusoidal wave whose frequency is a multiple of (n) of a fundamental horizontal frequency as a signal to be superimposed onto an audio intermediate frequency signal at a sender side. CONSTITUTION:An oscillation section 121 generates a sinusoidal wave whose frequency is nfH (fH is a horizontal frequency) synchronously with a synchroniz ing signal from a synchronizing separator circuit 113 and supplies the wave to an inversion switch 122. The inversion switch 122 inverts into a forward or a backward the nfH signal based on a control data from a data insertion device 133 and supplies the result to an AM modulator 102 as a privacy data QA. When the privacy data QA is extracted by a receiver side, the privacy data QA is converted inversely, reproduces an output data of a descramble timing data generating circuit 131 representing the synchronizing compression location to decide the generating timing of the expanded pulse. Thus, a key data of the descramble key data generating circuit 136 to apply inverse conver sion of the privacy data QA is sent to the receiver side via a formatter 137, an FSK modulator 138 and a mixer 104.

Title: Audio signal amplifier
Inventor: KUMAGAI KICHIJI
IPC: H03F3/68
Filed: 1984-04-27
Abstract: PURPOSE:To improve the distortion factor at a small signal by providing a class A single current amplifier stage, a class A, AB or B push-pull current amplifier stage and a transformer coupling electromagnetically outputs of both the current amplifier stages and obtaining a superimposed output signal so as to prevent a switching distortion at zero cross point from being generated. CONSTITUTION:When a large input signal is fed to a point A, a liner output of an input fed to the point A appears at a point B. Since a signal level at the point B is at the outside of the operating region of an amplifier 12, a voltage waveform at a point C is a waveform clipped at both peaks. A difference between the voltages at points B and C is fed to an amplifier 13 as an input signal, and an output waveform of the amplifier 13 is a waveform between the points C and D identical to the clipped waveform shown in broken lines and become discontinuous. The voltage with the clipped waveform at the point C is fed to a middle tap of the transformer 14, the clipped waveform at the point C and the discontinuous waveform at the point D are superimposed and the waveform is identical to that at the point B. Thus, an output waveform at a point E has no distortion.
