摘要： A method of preparing a paper having a reinforced strength wherein a polymer latex is added to a paper stock in an amount of from 2.5 to 30% by weight. The polymer latex is prepared by neutralizing a seed polymer with an acid or a salt or by quaternizing it with a quaternizing agent. The surfaces of the emulsion grains are provided with a large number of cationic groups. The seed polymer is formed by adding a monomer represented by the following formula (I) or a mixture of the monomer (I) and copolymerizable ethylenic unsaturated monomer(s) (II) to a seed latex of a carboxyl-modified synthetic rubber latex or synthetic resin emulsion and polymerizing them: ##STR1## R.sub.1 represents H or CH.sub.3 ; R.sub.2 represents an alkylene group having from 2 to 5 carbon atoms;R.sub.3 and R.sub.4 each represents H or an alkyl group having from 1 to 5 carbon atoms;A represents ##STR2## and R.sub.1, R.sub.3 and R.sub.4 are so selected that the monomer is hardly soluble or insoluble in water.The paper has a noticeably improved paper-strength.

摘要： A method and an apparatus for recording and reproducing a PCM audio signal either alone or together with a video signal, using a rotary-head type scanner. An analog audio signal is converted into a digital signal having a predetermined number of quantization bits in each predetermined sampling period. The digital signal is recorded on a recording medium such as a magnetic tape, and an analog audio signal is reproduced from the digital signal reproduced from the recording medium. In the reproducing mode, the signal reproduced from the tape is written into a memory where error detection, correction and deinterleaving are carried out, and the signal is then read from the memory and applied to a D/A converter. The write rate from the memory depends on the video field period, and the read rate depends on the sampling period. Accordingly, the difference between the write address and the read address of the memory depends on the difference between the field period and the sampling period. By changing a master clock, which defines the sampling period controlled by the read address, in accordance with the address difference, the difference between the video signal field period and the audio signal sampling period can be controlled and compensated.

摘要： Errors in input data are concealed by interpolation using a mean value and the previous word which are automatically interchanged in accordance with the conditions of occurrence of errors. A series of data words in the input data is first modified into a form in which when the input word is erroneous it is replaced by correct input word immediately preceding the erroneous word. Then, in association with each word in the modified data word series a mean value between words immediately before and after that word or between that word and a word thereafter is produced, and if that word is the replaced word it is further replaced by the mean value produced in association with that data. Thus, an independent error is concealed by a mean value between the correct word immediately before and after the erroneous word while continuous errors are concealed in such a manner that the last erroneous word is replaced by the mean value between correct words occurring immediately before and after the continuous erroneous words and the other erroneous words are all replaced by the correct word occurring immediately before the continuous erroneous words.

摘要： Digital data units representative of analog audio signal are constructed into a data unit sequence with an error detection code being added to each of the data units for detecting coding errors within the data unit, and data synchronizing signals are inserted one for every predetermined interval of the data unit sequence to constitute a PCM data sequence, which is recorded and reproduced. The number of times of coding errors detected within the data unit by the error detection code during the time period between one data synchronizing signal and the next following data synchronizing signal is monitored and when the number exceeds a first predetermined count, the audio output is muted, and when the number decreases below a second predetermined count which is much smaller than the first predetermined count, the muting mode of the audio output is released to prevent the noise output.

摘要： When error detection codes are added to a sampled signal word which is a digital version of audio information and a control signal which is a digital version of system control information to construct a data frame and a control signal frame, respectively, the error detection code for the data frame is generated under an arithmetic condition different from that for the control signal frame. In this manner, frame identification information is superimposed on the error detection codes. In a reproducing unit, the error detection codes containing the identification information are used to check an error in the reproduced sampled signal word and control signal and to effect the discrimination between the data frame and the control signal frame.
