    Abstract: A motor speed control circuit, for example, for the turntable drive motor of a phonograph record player, is of the type having a phase-locked loop including a frequencydivider with a dividing ratio which is changeable for altering the rotational speed of the motor, for example, so as to selectively establish turntable speeds of 45 rpm and 33 1/3 rpm, and has the gain of one of the components of the phaselocked loop, such as, the servo-amplifier, the loop filter or the phase comparator, varied in accordance with changes in the dividing ratio of the frequency-divider so that the loop gain of the phase-locked loop is maintained substantially constant regardless of the rotational speed of the motor.

    Abstract: PURPOSE:To display a stereoscopic picture in which an optical image with the parallax information from a subject caught by the first optical path selector varies in the same way as the original in accordance with a viewing angle by supplying through the second optical path selector, said optical image to a transmission-type screen to which incident light and transparent light are symmetrically applied. CONSTITUTION:A display unit 200 consists of a picture tube 6, an optical path selector 7 arranged on its phosphor screen 6a, and a transmission-type screen 9 arranged in front of the selector. When a picture signal S3D is supplied to the picture tube 6, pictures 0'10 to 0'50 are formed on the phosphor screen 6a. The optical path selector 7 is formed by arranging flat convex lenses 71 to 75. A shield Lb1 is arranged on the side of the convex lens while a shield Lb2 with a preset diametrical aperture W'0 is arranged on its flat surface at the section that is opposed to its center. One focal point is focussed at the center of the flat surface sides of these convex lenses 71 to 75 and the other focal point is focussed on the flat surface formed by the end of the shield Lb1 at the convex side of the lens.

    Abstract: PURPOSE:To stereographically display a color picture by correctly generating a picture element with right and left parallax information on the fluorescent screen which corresponds to the first and third semicylindrical lenses taking a color fluorescent stripe as a single unit. CONSTITUTION:When electron beams 5R-5B scan the first line in the double speed horizontal scanning, a color picture signal S01 is supplied to a cathode-ray tube. Simultaneously, the single picture element l of the left eye picture is formed at the preset position of a fluorescent screen 1, i.e. at the position which corresponds to the right side of a semicylindrical lens 8al that is provided for the first line is formed, and the single picture element l of the right eye picture is formed at the position which corresponds to the left side of the lens 8al. On the other hand, when the electron beams 5R-5B scan the second line following the first line, a color picture signal S024 is supplied, the single element of the left eye picture is formed at the position which corresponds to the right side of the lens 8a2 of the fluorescent screen 8a2 and the single element l of the right eye picture is formed at the left side of the lens 8a2. This can perceive a good color stereographic picture.

    Abstract: PURPOSE:To form a clock signal that synchronizes with a reproduced PCM signal by detecting an error component by comparing a clock signal formed by an AFC circuit to a data synchronizing signal separated from the reproduced signal and further by excluding the error component by frequency conversion. CONSTITUTION:AFC circuit 3 generates frequency Nfh'(1Xdelta) of reproduced synchronizing signal HD from frequency fh'. Here, delta is an error in comparison with the reproduced signal. This output and an output from crystal oscillator 13 are supplied to frequency converter 14, the output of which is applied to phase comparator 21. A reproduced PCM signal from terminal 17 is converted by tuning circuit 16 into a signal of a continuous frequency, which is applied to converter 18, whose output is applied to comparator 21 by way of BPF20 to make a phase comparison to the output of converter 14, detecting an error component. Additionally, BPF20 is applied with the output of VCO19 controlled by the output of comparator 21 and the output of VCO19 and that of BPF15 are supplied to converter 23 for frequency conversion, thereby outputting them with the error component canceled.

    Abstract: PURPOSE:To perform a color picture display with an electronic beam without a shadow mask and to realize the miniaturization with high image resolution for a color picture display, by providing a CRT containing a display screen which is divided in R. G and B regions in the direction of screen H. CONSTITUTION:The video signal supplied to an input terminal 1 is separated onto three primary color signals R, G and B by a color demodulating circuit 2. For these color signals, the time axis is compressed down to 1/3 by R, G and B signal processing circuits 3R, 3G and 3B respectively to output a compressed time axis during H/3 different from each other in a horizontal period (H period). These signals are added together by an adder 8 and amplified by an amplifier 9 to be fed to a CRT 10 having a screen divided into R, G and B display regions and in the direction of screen H. In such a way, the use of a shadow mask is eliminated and an electric gun which shoots a single beam is available to attain the miniaturization with high image resolution for a color picture display.

    Abstract: PURPOSE:To obtain the 3-dimensional picture signal of high quality by converting the video signal for reproduction of 2-dimensional pictures into a video signal for reproduction of 3-dimensional pictures via a converting circuit. CONSTITUTION:When the 2-dimensional S2D is supplied to a terminal 109 of a converting circuit 100, the pseudo 3-dimensional signal S'3D of the 3-dimensional video signal is obtained from memories 101A and 101B respectively. The signal S'3D is converted into an analog signal through a D/A converter 111 and then supplied to a fixed terminal 112a at one side of a switch circuit 112. While the signal S3D is supplied to the other fixed terminal 112b of the circuit 112 through a terminal 113. The video signal obtained at a mobile terminal 112c is supplied to a 3-dimensional reproducer 10. The circuit 112 is switched to a state contrary to that shown in the diagram in case the signal S3D is supplied to the terminal 113. Therefore the signal S3D is supplied to the reproducer 10, and a 3-dimensional picture of high quality is reproduced.
