Abstract: A drop-out detector circuit for use in a device such as a video disc player or the like is provided using a minimum of added components. The input analog signal read from the disc is compared with the upper and lower (maximum and minimum) reference levels provided for the A/D converter otherwise provided for converting the input analog signal to digital form. When either limit is exceeded, a drop-out signal is generated.

Abstract: A drop-out detector circuit for use in a data reproducing device in which a reproduced high-frequency signal is digitized. The most significant bit of the digitized signal is sampled, and its logic state detected over a predetermined number of sampling periods. Both high- and low-frequency drop-outs can be detected from the detected logic state pattern of the most significant bit.

Abstract: A digital television circuit in which the analog FM video signal is first digitized and all processing is performed digitally, including FM demodulation. Clocks at the subcarrier frequency and four times this frequency are synchronized with the horizontal synchronizing circuit or color burst signal.

Abstract: A method for recording and reproducing video and accompanying audio information whereby various reproduction modes are made possible, including displaying a still image with appropriate sound, without adversely affecting the quality of the played-back signals. A video format signal, containing two-dimensional image information, is divided into a plurality of blocks. Audio information is inserted into predetermined ones of these blocks, and video information is inserted in the remaining blocks. The video format signal is recorded in this form on a magnetic medium. Upon reproduction, the blocks into which the audio information was inserted are, for video reproduction, either masked or replaced with other video information. Control information, including information correlating the audio and video information and, preferably, error correcting code information, is also recorded.

Abstract: The invention relates to new trichloroacryloyl oxime compounds of the general formula (I) ##STR1## wherein each of R.sup.1 and R.sup.2 represents a hydrogen atom, a lower alkyl group, a benzyl group, a benzylthio group, a lower alkylthio group, a cycloalkyl group, a halogen atom, a styryl group, a halogenophenylthio group, a naphthyl group, or a phenyl group which may optionally be substituted by at least one substituent selected from the class consisting of a halogen atom, a nitro group, a lower alkyl group, a lower alkoxy group, a phenoxy group, a benzyloxy group, a lower alkylthio group, a thiocyanato group, a di-lower alkylamino group, a halogenopyridyloxy group and a methylenedioxy group, or R.sup.1 and R.sup.2, together with the carbon atom to which they are bonded, may form an aliphatic ring, said ring being optionally substituted by at least one methyl group, and their use as fungicides.
