摘要： PURPOSE:To prevent a system from breakdown and to specify a fault position, by connecting a common bus channel device to a common bus and a bus for an input and output controller, and thus preventing a bus fault of the input and output controller from extending to the common bus. CONSTITUTION:In the common bus control system wherein a central controller 3 is connected to the same bus with input and output controllers 9-13, and a main storage device 2, common bus channel devices 7 and 8 having an interface converting function or a data buffering function are connected to the common bus 1. Then, the plural input and output controllers 9-13 are connected in groups to the devices 7 and 8 through input and output buses 14 and 15. Consequently, a bus fault of the input and output controllers 9-13 never extends to the common bus, and the system is prevented from beins shut down to limit the fault range.

摘要： PURPOSE:To eliminate the need for jobs such as main class reading, listening to sub-class and interpretation to the content of failure, at a maintenance in charge station, by using the combination between a DC voltage polarity and a multi-frequency signal, and transferring failure information. CONSTITUTION:When a failure takes place in an exchange, the main class and the sub-class corresponding to the accommodated terminal number of a failure display are selected at a code conversion circuit 1. The main class is transmitted to an A, B line voltage control circuit 2, and a voltage to be applied to a relay line is selected and transmitted out of BB, B snd G. The sub-class is transmitted from a PB oscillation circuit 3 and one figure out of four figures assigned as the sub-class of the PB signal is transmitted to the relay line via a coupling transformer T. The DC signal and the PB signal transmitted from an unattended station are received at a maintenance in charge station and translated at the processor, allowing to read the content of failure automatically.

摘要： PURPOSE:To secure the correspondence between the amount of the stored coins and the calling frequency of the exchange side, by providing the coin storing pole inversion signal detection means and the continuous time identification means of the AC signals outside the aural band between the automatic exchange and the entrusted public telephone for simultaneous use of different types of coins. CONSTITUTION:Public telephone set PSZX for use of different types of coins is connected to public telephone trunk OGT-P for talking via switch frame SWF and in correspondence to public circuit unit PSLE. The PSZX stores the coins when the pole inversion signal of the coin storage is sent from OGT-P under the busy state. At this moment, the AC signals outside the aural band featuring different continuous times are transmitted from the PSZX and according to the types of coins. Receiving the signals, the PSLE generates the timing pulse to identify the types of coins due to the continuous time of the signal and then to operate call meter MET. In such way, the correspondence is secured between the amount of the stored coins and the calling frequency of the exchange side.

摘要： PURPOSE:To arrange so that an optimal threshold value corresponding to a phase detection output may be selected and a change in the output be met by providing a circuit to change a threshold value of a comparator for phase detection in accordance with the condition of detection output. CONSTITUTION:When a phase detection output of a row of ink droplets from an input end 34 is detected by a comparator 27, first a switch 32, 33 is put in ''OFF'' position and a threshold value is set at a maximum V1 by a resistance 28, 29. Then said value is compared by the comparator 27. If the threshold value was detected, it is the highest against a noise, indicating a satisfactory phase detection. On the contrary, if said value was not detected, the switch 32 shall be put in ''ON'' position, so that the threshold value voltage is equivalent to V2

摘要： PURPOSE:To arrange so that stable detection may be achieved even if the amplitude of a flow speed detection signal were changed, by obtaining a logic product of an output of a flow speed detection signal compared by a comparator for detecting a threshold value and an output compared by a comparator for detecting a zero cross point. CONSTITUTION:Ink droplet flow speed detection signal from an input part 30 is first converted to a direct current through a diode 31, a condenser 32 and a resistance 33, and then is compared with a threshold value indicated by a resistance 34, 35 by a comparator 36. After this process, the signal enters a logic product circuit 40. In addition, a flow speed detection signal is inputted to a comparator 39 through a resistance 37. The signal rises sharply to both positive and negative poles each time it crosses O volt, and reaches a saturation voltage when it falls. A logic product circuit 40 carries out a logic product arithmetic operation of a signal exceeding in value a sufficiently larger threshold value than the noise level of a flow speed detection signal and a signal which does not delay a detection time even if the amplitude of a detection signal were changed. Therefore, it is possible to detect the flow speed stably and control the flow speed of ink droplets stably.

摘要： PURPOSE:To maintain a constant deflection volume, regardless of a change in the velocity of ink globules, by detecting a flow velocity of ink blobules and by controlling with programs, using a micro CPU. CONSTITUTION:During the time when a pulse (a) is being generated from a charge pulse generating circuit 10, if a gate opening pulse (b) is generated from a micro CPU circuit 11 for printing control, a high voltage test pulse (c) is generated at a charge electrode 14 by a charge circuit 13 through an AND circuit 12, and ink globules are charged. A flip-flop 15 is also energized, and it goes into a counter 16 and a counting action is started. The charged ink globules are deflected by deflection electrodes 21a and 21b, and detected by a detector circuit 24. Then, they are detected by a comparator 26 through an amplifying circuit 25. By this output (e) the flip-flop 15 is reset and the counter 16 stops the counting. With this value of counting a comparison is made by a programmed control of a micro CPU 11, and the difference is fed back to a pump 17, and the flow velocity is controlled therewith.

摘要： PURPOSE:To satisfactorily remove echo even when an input voice signal is switched or a sound image localizing position is changed. CONSTITUTION:Voice signals from counter spots are converted to voice signals for respective speaker parts by sound image localization processing parts 31-3m corresponding to the spots. The voice signal for the same speaker part are synthesized by synthesizing means 20r and 20l, sounded and outputted from speaker parts Sr and Sl. The voices from the respective speaker parts are arrived at a microphone part M as echo. Transmitting signals containing echo components are transmitted while the echo components are removed successively through plural echo canceler parts 11-1m. The respective echo canceler parts 11-1m fetch the voice signals before sound image localization processing as reference signals for pseudo echo formation. In the case of the echo canceler between multiple spots to change the sound image localizing position, a switch part 60 is provided on the input side of the sound image localization processing parts, and the voice signals from the other spots are imparted to the sound image localization processing part corresponding to a change command.

摘要： PURPOSE:To maintain respective echo canceller parts in a state capable of removing echo signals well even when plural input sound signals simultaneously sound. CONSTITUTION:The input sound signals are converted to the sound signals for respective speaker parts by corresponding sound processing parts 31-3n. The sound signals for the same speaker part are synthesized by synthesis means 20r and 20l and sound-outputted from the speaker parts Sr and $1 and the sound reaches to a microphone part M as an echo. Transmission signals including echo components are successively passed through the plural echo canceller parts 11-1n to which the corresponding input sound signals are supplied as reference signals, the echo components are removed and transmission is performed. In this case, based out output from plural sound/silence detection parts 61-6n, a reception condition monitoring and controlling part 70 stops the adaptive operations of at least the echo canceller parts 11-1n to which the input sound signals of the sound are supplied as the reference signals when more than two input signals sound.
