摘要： Cleaning device for preventing discharge of fly from a card into the atmosphere of a carding room by an air stream emerging from spaces between a plurality of flat bars. A resilient sealing member is disposed in each space between two adjacent flat bars in such a manner that two free side portions of the resilient sealing member are always urged against to each rib of the above-mentioned two adjacent flat bars. Each sealing member is held by a link member of the link chains which carry the flat bars, each flat bar riding on two spaced curved bars. A cover plate is rigidly mounted on each curved bar in such a way that the cover forms a duct with the above-mentioned flat bars moving along the working passage facing the cylindrical surface of the main cylinder of the card and with the above-mentioned resilient sealing members. Consequently such ducts are formed at the two sides of the card. At least one discharge pipe is connected to each duct so as to discharge the aforementioned fly from the card.

摘要： A synchronization (sync) word detection apparatus which, on receiving a signal in which a sync word having a predetermined length (N) is inserted beforehand, detects the sync word out of a demodulated and soft-decided sequence of the received signal. A cross correlator (4) calculates a cross correlation value of the soft-decided and demodulated sequence fed thereto and the sync word. A threshold generating section (1, 2, 3) determines a means power of the demodulated and soft-decided sequence and generates a threshold value on the basis of the mean power. A comparing circuit (5) produces a detection signal when the cross correlation exceeds the threshold value. The apparatus reduces the false detection probability and misdetection prbability even when the receive field intensity sharply changes on a transmission path.

摘要： A carrier recovery circuit comprises a voltage-controlled oscillator with a .pi./2 phase shifter coupled to it for generating carriers of quadrature phase relationship. First and second phase comparators respectively detect phase differences between an offset QPSK modulated signal and the carriers of the quadrature phase relationship. Signal from the first phase comparator is delayed by a 1/2 symbol duration and applied to one input of a quadri-phase detector having stable phase angles at .pi./4, (3/4).pi., (5/4).pi. and (7/4).pi. radian and signal from the second phase comparator is applied to the other input of the quadri-phase detector. A bit timing recovery field (1010 . . . 1010) of the second channel is detected from the output of the second phase comparator. Signal from the quadri-phase detector is applied to a loop filter and thence to the voltage-controlled oscillator during the time when a bit timing recovery field (BTR) of the second channel is not still detected. To stabilize the operation of the carrier recovery loop of the circuit, the output of the second phase comparator from which that BTR is detected is briefly applied to the loop filter in response to the detection of a BTR of the second channel, instead of the signal from the quadri-phase detector.

摘要： In a phase controlled demodulator, a modulated digital input signal is demodulated into quadrature signals with a carrier recovered by a voltage controlled oscillator. A phase difference between the quadrature signals is detected by a phase detector of Costas loop and applied through a loop filter to the voltage controlled oscillator to control the frequency and phase of the recovered carrier when the frequency deviation between the received and recovered carriers is within a phase control range. When the frequency deviation exceeds the phase control range, the output of the phase detector is a beat of the two carriers and a frequency sweep control voltage is applied to the VCO to search for the missing carrier. The magnitude of the beat is detected and compared with a predetermined threshold value. When the frequency deviation is far beyond the control range, the magnitude of the beat is lower than the threshold, but exceeds it at the instant the demodulator enters the control range, whereupon the frequency sweep control voltage is removed from the VCO.

摘要： A circuit for extracting a carrier wave signal from a double binary PSK signal input is disclosed. The PSK input signal is applied to a first frequency doubler which doubles the frequency of the input signal. The output of the first frequency doubler is applied to a second frequency doubler and to first and second band-pass filter circuits. The second frequency doubler serves to quadruple the frequency of the PSk input signal and derives a signal having a line spectrum at the frequency 4fc whenever there is no phase shift between successive time slots of the PSK signal. The first and second band-pass filters derive first and second signals having line spectra at frequencies 2fc + fs and 2fc - fs, respectively, whenever there is a phase shift of +90.degree. or -90.degree., respectively, between successive time slots of the PSK input signal. The outputs of the band-pass filter circuits are combined in first and second frequency mixers with a clock frequency signal which is synchronized with the clock frequency component of the input signal. The outputs of the frequency mixers are combined in a first signal combiner circuit whose output is applied to third frequency doubler. The output of the third frequency doubler has a line spectrum at 4fc whenever there is a .+-. 90.degree. phase shift between successive time slots of the PSK input signal. The outputs of the first and third frequency doublers are combined in a second signal combiner and applied to a carrier wave synchronizing circuit which derives the desired synchronized carrier wave.

摘要： A satellite packet communication system comprising a central station and VSAT stations. The central station generates chip-rate clock pulses and transmits a series of data on timeslots of a frame to a satellite transponder, and a plurality of terminal stations. Each VSAT station receives the frame from the transponder and recovers the chip-rate clock pulses from the received frame. A pseudorandom number (PN) sequence generator, provided in the terminal station is synchronized with the recovered chip-rate clock pulses for generating bits of a PN sequence with which packetized data bits are pseudorandomly modulated and transmitted in burst form to the transponder. The central station includes a correlator which is synchronized with the central station's chip-rate clock pulses to detect correlations between the pseudorandomly modulated data bits a sequence of pseudorandom numbers corresponding to the PN sequence bits of the terminal stations.

摘要： In an error correcting apparatus, an add-compare-select circuit is provided for each state in a given time slot of a Viterbi trellis diagram. The ACS circuit includes first and second pairs of adders coupled to a source of sequentially updated path metrics and to a branch metric generator which generates sums of branch metrics over successive time slots. The updated path metrics of states two time slots prior to the given time slot and the branch metric sums are added up in the adders. The outputs of adders in pairs are compared respectively by first comparators to determine the highest of the adder outputs. The determined highest values are passed through first selectors to a second comparator to further determine the highest of the selected adder outputs, the further determined value being passed through a second selector to the path metric source to update the previous value. Control signals indicating the determinations taken by the first and second comparators are coupled to a path memory for storing data indicating the paths of the selected values.
