    Abstract: A device which supplies timing signal for speed error compensation was composed of many parts, namely, a signal part from the signal storage disk, a part which separates a certain signal from the other signal, a part which detects signal, an output part which generates signal in response to detected signal, a blanking part which generates signal during the vertical synchronizing, and a part which controls speed of disk.

    Abstract: This cct. was composed of Tr. (10) for output, an auxiliary Tr.(20), a res. (25), a volt detecting Tr.(30) and a clamping Tr.(40), the base-emitter of Tr.(10) was k times that of Tr.(20). when an overcurrent flows this composition cct., a part of the collector current of Tr.(10) flow through res.(25) and then the base-emitter or Tr. (30) is turned "ON" by the volt. of res(15) biasing Tr.(40). Thus, the base-emitter of this cct. is clamped.

    Abstract: Signals representing the colour images are analysed by a line scanning process of a given line scanning frequency. The signals are subjected to signal component removal at regular intervals, each corresponding to a non-integral multiple of the line scanning frequency in a given band. Device including a comb filter develops signals representing the images chrominance and occupying only the given band. The comb filter removers chrominance representative components at a scanning group of regularly spaced locations, each an integral multiple of the line scanning frequency.
