摘要： A time-constant circuit suitable for being fabricated into an integrated circuit comprising a resistive element with its one end connected to a first input terminal, an impedance converting circuit with its input connected to another end of said resistive element and its output connected to an output terminal, a variable gain differential amplifier with its one input connected to the output of said impedance converting circuit and its another input connected to a second input terminal, an adder circuit for adding an output from said amplifier and an input signal appearing on said second input terminal, and a capacitive element connected between the junction of said resistive element and said impedance converting circuit and the output of said adder circuit. A plurality of the time-constant circuits are combined to construct a filter circuit. The gain of the variable gain differential amplifier in each time-constant circuit is controlled by a common DC voltage, whereby the spread of characteristic values of the integrated circuit elements can be compensated.

摘要： A chrominance signal reproducing apparatus is proposed, in which an oscillation frequency of a first voltage-controlled oscillator is controlled by each of the error control voltages produced from APC and AFC circuits and the signal having the frequency component of the 1/4 output frequency of the first VCO and the output frequency signal of a second VCO are added to produce a sum frequency, which is used to frequency-convert a low-frequency converted carrier chrominance signal to a carrier chrominance signal before low-frequency conversion. The AFC circuit operates only when the frequency F'.sub.sc of the carrier chrominance signal before the low-frequency conversion is deviated 1/8 f.sub.H (f.sub.H : horizontal synchronizing frequency) or above with respect to the carrier chrominance frequency f.sub.sc, so as to apply the control voltage to the first VCO thereby to drive the deviation within the range of .+-.1/8 f.sub.H. When the f'.sub.sc is in the range of f.sub.sc -1/8f.sub.H

摘要： A time lapse magnetic recording/reproduction apparatus for recording and reproducing picture signals while intermittently thinning them out in a frame unit is used for monitoring and burglar-proofing in plants, shops, banks, etc. Recording picture information is generated and added to one continuous picture signal obtained by sequentially switching the output of each video camera, and is then recorded. A speed multiple k for a normal tape travelling speed is optimally set by servo circuit on the basis of the recording picture information (the total number m of channels) detected from the reproduction picture signals reconstructed by double-azimuth four heads at the time of search reproduction, and a search reproduction picture throughout the full screen of a monitor television is obtained in full recording channels. At the same time, a write period into an image memory is controlled in accordance with the recording picture information (the total number m of detection channels) and a reproduction head signal level, and read controller then controls sequentially readout of the picture signals from image memory storing therein only specific channels.

摘要： The present invention provides a magnetic recording and reproducing unit of a helical scan type having a slow speed tape running mode in which the speed of running a magnetic tape is slower than that of a standard running mode. The magnetic recording and reproducing unit of the present invention has a pair of azimuth heads of mutually different azimuthal angles which are mutually adjacently disposed on the outer periphery of a rotating cylinder and another pair of azimuth heads of mutually different azimuthal angles which are mutually adjacently disposed at positions symmetrical with the first pair of azimuth heads with respect to a rotating center of the rotating cylinder. Each pair of the two pairs of azimuth heads alternately traces tracks recorded with image signals on a magnetic tape to reproduce the recorded image signals. Further, the magnetic recording and reproducing unit of the present invention has a control head for reproducing from the magnetic tape a control signal which is synchronous with a header position of the recorded tracks, a traced azimuth predicting signal generating unit for generating a predetermined azimuth change over signal in response to the control signal, and a switching unit for selecting one of reproduced image signals from the pair of azimuth heads according to the change over signal in the slow speed running mode.

The recording/reproducing apparatus may include a reader which reads the search reproduction picture from the memory. The search reproduction picture may changes intermittently during search reproduction.
