Abstract: PURPOSE:To detect the phase difference of the desired signal and the unnecessary signal correctly, by detecting the zero cross position of the output of the sampling circuit in which the sampling circuit and the sampling position are variable, and by using the detection signal delayed by 1/4 or 3/4 than it. CONSTITUTION:The output of the sampling circuit 15b sampling the demodulated output in which the sampling circuit 15a and the sampling position are variable, is fed to the zero cross detection circuits 33a and 33b and each zero position is detected. The sampling pulse is respectively produced 36a and 36b at the position delayed by about n/4 or 3n/4 from each zero cross position. The sampling pulses Pd and Pu are added to the output of the circuit 15a and 15b with the gates 27a and 27b, the level is compared and DU ratio is displaying 30, and it is fed to the sampling gate 38a and 38b and the level is compared 40. Thus, the phase difference between the desired signal and unnecessary signal is correctly detected.

Abstract: PURPOSE:To make the necessary patterns glow in order to increase the visual impression as well as to enhance studying effect by setting picture card in front of the TV screen. CONSTITUTION:Both the still and motion pictures are drawn on the card with magnetic tape part 3 provided. Part 3 contains the video track and the one on which the information to project the necessary patterns. Thus, the pattern signals of part 3 are written into the field memory and then read out to the TV. The TV screen is partitioned in measure corresponding to the memory, and then the necessary patterns are made to glow selectively. And at the same time, the pictures on the card are illuminated from the back side in order to creat the dynamic effect.

Abstract: PURPOSE:To simplify the structure greatly as well as to increase the accuracy for the telecine device by performing the field scanning via the linear beams. CONSTITUTION:The light given from spot 7 of flying spot tube 1 is converted to line 8 in the horizontal direction via semicylindrical lens 2, and the light on line 8 is irradiated onto film 3. Scanner 6 performs the horizontal scanning while line 8 has a scanning in 1/60 sec. from the upper end to the lower end of frame 4a of film 3. Thus, the TV video signal which is equivalent to 1 field and contains the informations according to the picture of frame 4a can be obtained through scanner 6. Then the 2-field video signal is obtained by scanning frame 4a twice at line 8, and then the 3-field video signal is obtained by scanning next frame 4b three times via line 8. After this, the scannings are performed alternaltely in the same way in order to secure synchronization between the frame of film 3 and the TV field.

Abstract: PURPOSE:To realized deletion of the disturbing signals for the vestigial side-band modulation system of TV by producing a number of combination signals through the matrix circuit and then selecting these signals. CONSTITUTION:Detection output Sd of the modulation signal becomes as Sd = 1/2 + 1/2.mg (t) + K/2.mcosphig (t + pi) + 1/2.Kmsinphig (t + t) h (t + tau) hen the disturbing signal featuring delay time and amplitude ratio K to the original signal is piled on the modulation signal. Then the member containing cosphi and the member containing sinphi are compounded together to draw out 1/2 + 1/2.mg (t), and then subtracted form signal Sd to be deleted. The signal sent from subtraction circuit 2 is supplied to n-bit delay circuit 11, and the output of each unit form circuit 11 is supplied to matrix circuit 12 through filter 7 and via switch Wj. Thus, the signals of m types are formed and then drawn out via switch Xi, and the deletion signal is formed through proper selection of Wj and Xi.

Abstract: PURPOSE:To secure the control of the power supply and the reception channels for the picture main body through reception of the control signal extracted selectively via the switch circuit and transmitted. CONSTITUTION:At controller 20 located separately from picture receiver main body 10, the control signals for the power supply ON/OFF and the channel switching are obtained from control signal generator circuit 41 by the key operation through keyboard 25. This control signal is modulated 43 and supplied to transmission part 44 to be transmitted via the ultrasonic wave, light, electric wave and the like by switching previously change-over switch 42 to contact M. The signals received 11 at main body 10 are demodulated 13 via amplifier 12 and then decoded 14, and the extracted ON/OFF signals of the power supply are supplied to power circuit 15. At the same time, the extracted channel information is written into memory 16, and the output undergoes channel selection 18 via channel control circuit 17. And the selected 18 channel is displayed 19.
