    摘要： A wide bandwidth color video signal, such as a high definition television (HDTV) signal is recorded on a video disc by timebase expanding the luminance component and timebase compressing the color difference components to a bandwidth substantially equal to the bandwidth of the timebase expanded luminance component. The timebase expanded luminance component and the timebase compressed color difference components are time division multiplexed and separated into plural channels of multiplexed signals, each of which is recorded in a respective track on the video disc. Signals recorded in this format are recovered by reproducing the plural channels of multiplexed luminance and color difference components from respective tracks, demultiplexing the timebase expanded luminance component and the timebase compressed color difference components, timebase compressing the separated luminance component to return it to its conventional timebase, and timebase expanding the separated color difference components to return them to their conventional time base.

    摘要： A dropout correcting apparatus has a dropout detecting circuit for detecting a dropout from a reproduced video signal. A mixing circuit superimposes a dropout detecting flag signal from the dropout detecting circuit upon the reproduced video signal. A time base fluctuation correcting circuit removes a jitter component of an output signal from the mixing circuit. A dropout detecting signal separating circuit separates the dropout detecting flag signal from the output signal of the time base fluctuation correcting circuit, and a dropout correcting circuit corrects the dropout of the reproduced video signal in response to the separated dropout detecting flag signal.

    摘要： A camera platform, which is mounted on a tilt member by means of a shaft, is allowed to rock around the shaft, between a horizontal position and a vertical position. A bracket of the platform can slide relatively to a support portion of the tilt member, in the axial direction of the shaft. First and second recesses are formed in an end face of the bracket. The support portion of the tilt member is formed with a projection, which is fitted alternatively in one of the recesses. When the platform is in its horizontal position, the projection is fitted in the first recess. When the platform is in its vertical position, the projection is fitted in the second recess. The projection can be disengaged from the first or second recess by only sliding the bracket of the camera platform in the axial direction of the shaft.

    摘要： A device for fixing a camera to a tripod which comprises a base and a slider to which a camera is to be fitted. Both base and slider are prepared from synthetic resin. The slider is slidably fitted on the base. One of the slider and base is provided with a projection, and the other thereof is provided with an integral elastically deformable piece. This deformable piece involves a protrusion engageable with the above-mentioned projection when the slider is set on the base, and a free end which allows for the elastic deformation to remove the slide from the base.

    摘要： A sintered ceramic has a porosity of greater than about 30 percent and less than about 80 percent by volume. Pores are filled with an epoxy resin. A filling factor of the epoxy resin is about 40 percent by volume or more. A monolithic ceramic electronic component having an inner electrode, for example, a chip inductor is manufactured with such a porous sintered ceramic. When a direct current is superimposed, the resulting monolithic ceramic electronic component has a substantially unchanged self-resonant frequency and also has a rate of decrease in impedance of about 50 percent or less at 100 MHz.

    摘要： An optical disc device is equipped with a high-pass filter for removing a low-frequency noise in a played-back signal, an adder for adding the output signal of the high-pass filter and a correction signal as a low frequency component lost from the played-back data at the noise removal, a first comparator for binarizing the output signal of the adder, and a low-pass filter, having a frequency characteristic complementary to that of the high-pass filter, for suppressing a high frequency component of the output signal of the first comparator to generate the correction signal. In addition, a second comparator for binarizing the output signal of the adder taking a slice level as a reference and outputting played-back data and a controller for varying the slice level and/or a direct current level of the output signal of the adder so that a duty ratio of the played-back data becomes a prescribed value are provided. Thus, the influence of low frequency noise can then be effectively avoided and high-density recorded data can he surely played-back even when the d.c. level of the played-back signal fluctuates due to variations in the laser power.
