摘要： PURPOSE:To use a direct memory controller, which is used before extension, continuously when plural memory devices are extended, by specifying areas requiring access in respective memory devices and by adding a simple-constitution switching device. CONSTITUTION:A processor 1 and a direct memory access controller 2 are connected by a data bus 5 and the 0th - the 13th digit lines 61 as an address bus. These digit lines 61, the 14th digit line 62, and the 15th digit line 63 are distinguished from other digit lines and are connected to memory devices 31-34 having specific areas 311-341 requiring access. A control line 70 from the processor 1 is connected to devices 31-34 through a register 7 to designate respective devices 31-34. The 0th - the 13th digits of the memory address signal from the controller 2 are connected to digit lines 61 directly, and two bits of the 14th - the 15th digits are connected to digit lines 62 and 63 or a decoder 8 through a switching circuit 11. Thus, the controller is used continuously when devices 32-34 are extended.

摘要： PURPOSE:To raise the precision of fitting of a type head to a selecting axis and facilitate the preparation by engaging insert arms with an insert-retaining pin and molding all in a unitary body. CONSTITUTION:An upper mold 17 being removed, an insert 11 is fitted to an insert-retaining pin 15, a chipped part 16 being pressed against a plane 12. Each arm 13 is engaged with the insert-retaining pin 15. Under the condition, the upper mold 17 is put on a lower mold 14 and the synthetic resin is poured into the molds, thereby a type head being formed. Accordingly, the insert 11, being tightly pressed against the insert-retaining pin 15, is molded solidly with the resin. Therefore, the type-head being fitted to a selecting axis, the plane plate 12 is stuck fast to the chipped part of the selecting axis, while each arm 13 being stuck to the peripheral surface on the opposite side to the chipped part of the selecting axis. In this way, the part requiring the anti-abrasiveness is to be formed by a contact of metallic parts, which improves the anti-abrasiveness. In addition, since the sufficient fitting precision can be obtained by processing the insert-retaining pin with high precision, the processing can be facilitated.

摘要： PURPOSE:To realize each constitution circuit economically by dividing and multiplexing the frequency by means of a transmitting circuit and a signal incoming from each input circuit to transmit it to each receiving circuit and selecting and receiving a signal in a necessary frequency band in a receiving circuit which is an exchanged and connected object. CONSTITUTION:Each transmitting circuit 3-i (i=1-n) modulates an original signal d0 from an input circuit 1-i by means of an inherent carrier fi, and after it converts the signal into a convertion signal di through a BPF32, it transmits the signal to a single bus 5. As the result its frequency is divided and multiplexed, and transmitted to each receiving circuit. A receiving circuit 4-j (j=1-n) separates the convertion signal di by BPFs 41-1-41-n and demodulates it to the original signal d0 in demodulators 42-1-42-n. On the other hand, a common control circuit 6 specifies a carrier to be selected for the receiving circuit based on exchange information. For instance, when the input circuit 1-n is exchanged and connected to an output circuit 2-1, the circuit 6 specifies the carrier fn with respect to the circuit 4-1, which selects an output signal of the demodulator 42-n by a selecting circuit 43 and transmits it to the output circuit 2-1.

摘要： PURPOSE:To avoid an increment of hardware, by mixing both sound and control data on the same highway to transmit them, and detecting a fault of the sound data separated from a signal. CONSTITUTION:A pattern of the sound data for detection of fault is transmitted to a common part 3 of line concentration stage from a distributing stage 4 and then fed to a parallel-serial converting part 36 via a line concentration switch 32 to be mixed with the control data fed from a control memory 34. The mixed data is sent to a separating part 12 of a subscriber line interface part 1 through down-highways 207 and 208 to be separated to the sound and control data. Then the sound data is folded and mixed with the down-control data at a multiplexing part. This mixed data is sent to a serial-parallel converting part 35 through up-highways 205 and 206. Then only the sound data is sent back to the stage 4 via a line concentration switch 31. The contents of the sound data are checked at the stage 4. Then it is decided that the control highway has no fault if no fault is detected with the contents of the sound data.

摘要： PURPOSE:To ensure the stable operation for subscriber circuits in the same unit, through the suppression of heat generation value, by suppressing the number of simultaneous calls a prescribed number or more for a plurality of subscribers in the unit. CONSTITUTION:A plurality of subscriber circuits are loaded in one unit and a subscriber terminal 7 is connected to a power supply 26 via a telephone cable 6, equivalent power feeding resistors 23, 24 and a channel controlling circuit 25. The circuit 25 controls a channel current with a signal from a subscriber circuit controlling circuit 29 receiving the subscriber state signal of a subscriber state monitoring circuit 28. In this case, the controlling circuit 29 discriminates a subscriber state signal and gives a channel current stop signal to the control circuit 25 of subscriber circuits which are not busy, when the simultaneous calls of the subscribers in the same unit is a prescribed criterion or over. Thus, the circuit 25 inhibits the calling of the subscribers except tentative call.

摘要： PURPOSE:To suppress the production of discharge based on the pyroelectricity when a rapid temperature change is caused, by covering the crystal surface except the energizing converter and reception converter with electric conductor and covering the residual surface including the converters with resistive film. CONSTITUTION:On the surface of the piezoelectric crystal plate 41 having pyroelectricity, the reed-screen-shaped electrode by the conductive thin film is formed with photoetching, one reed-screen electrode is taken as the energizing converter converter 12R is covered with the metallic film 42 being electric 12S and another reed-screen electrode is taken as the reception converter 12R. The surface of the crystal plate 41 except the energizing converter 12S and reception conductor and the surface forming the converters 12S, 12R is covered with the resistive film 43. The film thickness (h) of the resistive film 43 and the specific resistivity rho are obtained so that rho/h is ohms - >=10 ohms at room temperature. Further, if rapid temperature change is caused to the crystal plate 41, the production of discharge based on the pyroelectricity is suppressed, allowing stable operation.

摘要： PURPOSE:To simplify the control for path setting by using the bit of a digital control signal after inverting it at the side of a switch having (n) pieces of inputs and (n/k) pieces of outputs respectively. CONSTITUTION:Highways 10 and 20 are multi-connected to switches 1 and 2 respectively, and a controller 3 controls the connection between input and output highways. Then the same control information is supplied to the switches 1 and 2 respectively from the controller 3 via a control information line 30. The control information of the switch 1 is edited at a bit inversion editing part 12 provided at a control signal receiving part; while the control signal of the switch 2 is edited by a bit inversion editing circuit 22 provided at the control signal receiving part respectively. The digital control signal has a binary display, and the specific bit of the control signal functions to group the highways 10 and 20. As a result, the controller 3 can perform its control operation regardless of the operating difference between switches 1 and 2 due to storage of highways.
