Abstract: A signal transmitting-receiving system which has a signal transmitting side system constructed by signal transmitter T1, voice processor T2 and signal receiver T3 and also has a signal receiving side system constructed by signal receiver R1, synthesis circuit R4, signal transmitter R5 and delay circuit R3. The signal transmitting-receiving system is constructed such that no processing for making a video signal coincide with a voice used in communication using voices in position on a time axis is performed.

Abstract: A digital-to-analog converter which is effective for an interpolative decoder for decoding a linear PCM signal is disclosed. An output signal of a binary rate multiplier which develops signals of several less-significant bits of the linear PCM signal onto a time axis is directly applied to a driver circuit, by which is driven the segment of a ladder resistance network corresponding to the least significant bit, the ladder resistance network having segments corresponding to signals of several more-significant bits of the linear PCM signal. Thus, an adder for the digital addition between the output signal of the binary rate multiplier and the signals of the several more-significant bits is dispensed with.

Abstract: An interpolative PCM decoder converts PCM signals having polarity bits, segment selection bits and uniform quantization bits into an analog signal. The PCM decoder may be used both for .mu.-law and A-law conversion by use of simple circuits and includes an AND gate circuit which produces a logical product between a selection signal for selecting a minimum unit of an analog value of a lower end of a segment and a control signal for change-over between the .mu.-law and the A-law, and a circuit generating the same analog values as the minimum unit of the analog value in accordance with an output of the AND gate circuit.

Abstract: This invention relates to a process for producing a curl shrunk silk yarn. One of the features of the invention is to absorb collagen derived protein into raw silk material after sericin is removed therefrom. Thereafter, silk fibers are twisted in a S- or Z-direction and then saturated with moisture. Another feature of the invention is to maintain the moisture saturated silk fibers at prescribed temperature and under prescribed pressure for a given time. Thereafter, the fibers are untwisted in the reverse direction and given a curl shrinkage characteristic under the circumstance of saturated vapor.

Abstract: In accordance with the present invention, there is provided an economical and compact frequency sampling filter comprising a comb filter and resonators, in which the difference between the output of a frequency sampling filter of the bandpass type or the low-pass type, or the bandstop type or the high-pass type and the output of a circuit having the same gain as that at each sampling point in the pass band of said filter and having a similarly varying phase to that in the pass band is obtained.

Abstract: A multi-frequency signal receiving circuit comprising a check circuit for discriminating the existence of a predetermined number of signal frequencies constituting a signal to produce an output, a timing circuit for delaying the output of the check circuit, a rectifying circuit for receiving the signal to detect the received signal energy and produce an output, a timing circuit for delaying the output of the rectifying circuit, an AND gate circuit for receiving the outputs of the two timing circuits to produce an output, and control means for controlling the transmission of the signal to the output circuit of the receiving circuit in accordance with the output of the AND gate circuit, whereby the normal operation of the receiving circuit can be ensured even when the signal frequencies arrive with a large arriving time difference and the operation start time is quickened.
