摘要： The present invention relates to a cue signal recording method in which multi-audio tracks are formed by dividing a magnetic tape in a widthwise direction, and PCM data is recorded in a scanning track segment of an audio track of the multi-audio tracks by a helically scanning rotary head. A cue signal is then recorded in a remaining area of the scanning track segment except for the area recorded with the PCM data, such as in the after-recording-margin area or the track-guard area which is immediately after the PCM data area.

摘要： In a helical-scan tape recorder, a digital signal having a series of M identification words of N bits each is generated. One of the N-bit words is a discrimination word identifying a particular combination of the other N-bit words. The M words are organized into J groups of I words each (where J.times.I=M) and recorded with an information signal at spaced intervals within each of a series of sectors defined along each track of a recording tape so that the word groups are interleaved with the information signal and each of the recorded sub-blocks can be traced substantially simultaneously by a transducer head during a search mode. At least one of the word groups includes data bits identifying distinct, but mutually closely related items of information and discrimination bits which identify the data bits. During search mode, distribution bits can be detected with the data bits of the same word group to allow the closely related items of information to be displayed.

摘要： A circuit for reproducing informaiton signals and four different tracking control pilot signals recorded on respective tracks on a magnetic tape and producing from the pilot signals a tracking error signal indicative of a relative positional deviation between each of a plurality of magnetic heads and each track of the tape. The circuit includes a balanced modulation circuit for successively multiplying reproductions of the pilot signals and a reference signal to produce a multiplication output signal having components corresponding to the respective pilot signals. Respective tuning circuits derive first and second signals from the multiplication output signal, having different frequency components and corresponding to different ones of the pilot signals. A level comparison circuit compares the first and second signals in level to produce a level-compared output signal whose value is indicative of the relative levels of the first and second signals, the level-compared output signal having respective portions corresponding to successive periods of reproducing signals on tracks on which different ones of the pilot signals are recorded. A further portion of this circuit time-divisionally extracts the values of levels of the level-compared output signal. A further comparator calculates the values of the differences between at least two of the extracted level values to produce the tracking error signal. The circuitry eliminates any variations in the tracking error signal which may be caused by any variations in mechanical height of the magnetic heads.

摘要： A two speed or multi-speed video tape recorder of the conventional helical scan type in which the audio signal is capable of being recorded as a time compressed signal at one end of each helical video scan, or alternatively, in conventional longitudinal fashion by means of a stationary magnetic head engaging one edge of the tape.At low tape transport speeds, improved bandwidth (and therefore sound fidelity) is obtained by use of the time compression technique; while at higher transport speeds, there are advantages in utilizing the stationary audio head.Circuitry is provided to automatically utilize the time compression technique at lower tape transport speeds and the stationary head longitudinal recording technique at higher tape transport speeds. A pilot or cue signal is recorded on the tape, to automatically control the reproduction circuitry so that both types of recording methods can be interchanged on the same magnetic tape, with the reproducing circuitry switching accordingly between the two modes, as required.

摘要： A process for the preparation of a 5,5'-bi-1H-tetrazole diammonium salt by dropwisely adding the aqueous hydrogen peroxide to which a small amount of weakly acidic substance has been added, to a starting aqueous solution containing hydrogen cyanide or sodium cyanide or potassium cyanide, sodium azide and a catalytic amount of copper sulfate preferably at a low temperature to maintain the pH of the reaction solution over a range of from 5 to 6, heating the reaction solution to effect the oxidation and cyclization reaction, reacting the reaction product with ammonium chloride or an aqueous solution thereof, and recovering the formed ammonium salt in the form of sparingly soluble crystals. The desired product is obtained in a high yield and in a high purity from the starting materials which are cheaply available and are easy to handle through a decreased number of steps, i.e., through a one-pot reaction without requiring cumbersome after-treatment.

摘要： A video recording and reproducing apparatus with photoelectric image camera in which a color signal processing circuit of a recording system is simplified. For recording, a luminance signal and a chrominance signal are produced in accordance with an image being picked up through a photoelectric transducer. The luminance signal is angle-modulated, while a carrier signal having a lower frequency than the standard carrier signal is directly modulated with the chrominance signal, whereby a chrominance recording signal equivalent to a signal obtained by a frequency conversion of the standard carrier signal to a low frequency band is obtained and added with the angle-modulated luminance signal to be recorded. Upon reproduction, the angle-modulated luminance signal undergoes angle-demodulation to be converted to a reproduced luminance signal, while the color (chrominance) recording signal is frequency-converted to a high frequency band to be reproduced color signal. The reproduced luminance and color signals are added together to obtain a reproduced color video signal.
