Filed: 1986-01-17
Abstract: PURPOSE:To remove impulsive noise by providing a limiter circuit on the poststage of an FM demodulator and varying an amplitude limitation center level in accordance with an FM modulation output corresponding to a non- modulating period of a modulating signal. CONSTITUTION:The limiter circuit 22 for limiting the amplitude of a sound signal to be an impulsive noise by FM modulation is connected to the poststage of the FM modulator 15 for modulating an FM modulating video signal, a preamplifier signal to be the non-modulating carrier of said FM modulating video signal and a TV signal obtained by multiplexing a PSK modulating sound signal with time division. The center level of the amplitude limiting with of the circuit 22 can be varied based on an output of a sample holding circuit 23 for sample-holding the FM modulated output during a sample holding period. Consequently, the circuit 22 can limit the amplitude always following the FM modulated output corresponding to the non-modulating period independently of the contents of the modulated signal, so that bad influence due to the frequency variation of the FM carrier which may be exerted upon the limiter effect can be removed and the impulsive noise can be also removed.

Abstract: PURPOSE:To prevent recorded information from being erased against the user's will and to securely erase the recorded information of an erasing object only by inhibiting an erasing operation of recorded information at the time of continuously reproducing plural bits of information. CONSTITUTION:When an erasing switch 33 is pressed under the displaying state of a desired picture at a monitor 19, whether the mode is a drive mode or a reproducing mode is decided, and if it is a normal reproducing mode, 1st erasing processing is executed.

On the other hand, when a continuous reproducing mode is set, the drive mode is once changed from the continuous reproducing mode to the normal reproducing mode. Consequently, even when the continuous reproducing mode is set, the erasing is performed on each track one by one, and the erasing of a recording track against the user's will can be prevented.

Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To provide a printing data transfer device which can shorten the total of compression time and transfer time required for transfer of printing data. SOLUTION: A compression time measuring circuit 17 determines the time required for compressing one page in the previous measurement. A compression, transfer indication means 19 determines a minimum number of pages such that the transfer time under condition of non-compression is longer than the previous compression time of one page. A transfer circuit 14 transfers printing data corresponding to the minimum number of pages from the top thereof without compressing the data to a printing device 12. In parallel, pages to be transferred next are compressed by means of a compressing circuit 15. After completion of transfer of non-compression data, compressed data are transferred to the printing device 12 via the circuit 14. Since compression and transfer are performed parallelly to each other, the total transfer time can be made shorter.  And transfer can be effected without disturbing the order of pages.
