    摘要: A plurality of different fault locating functions are provided in a communication system comprising a plurality of terminals connected to a data transmission channel. The functions are at different levels, respectively, ranging from a level for rapid fault location to a level for reliable and sure fault location. Upon detection of an occurrence of a fault, one fault locating function is performed. If the fault is not located accurately located, another fault locating function of a level for more reliable is performed, thus the functions are performed sequentially in the order from the level for rapid location to the level for more deliberate and reliable location. Preferably, the channel is reconfigured to avoid the fault, according to the fault located by the functions of the respective levels. With this arrangement, a fault which does most possibly occur can be located quickly, while another fault difficult to locate can be located accurately.

    摘要: Method and apparatus for instruction restart processing in a microprogram - controlled data processing apparatus, wherein, in restarting an instruction execution after instruction suspension, the internal information of the data processing apparatus at the time of instruction execution suspension is saved in a memory, and after a suspension cause removal process performed the saved internal information is recovered. A check point address associated with the address of a currently executing microprogram is stored in accordance with a designation by the microprogram. After a suspension causes removal process is performed, the execution of the instruction restarts using the check point address. If a check point address has not been stored after the suspension cause removal process is performed, the execution of the instruction restarts from a read operation of the suspended instruction from the main storage.

    摘要: A central station and a plurality of transmission stations are connected in cascade by a serial transmission line, and constitute a looped data highway system. The central station controls the whole system. The system allows the transmission station having a data signal transmission request to send out a data signal by means of a normal polling signal, but only the station having sent out the data signal by means of the preceding normal polling signal is allowed to send out the data signal again in response to a retry polling signal.

    摘要: In a convergence distortion correction method and apparatus for raster-scanned color CRT having a dynamic convergence magnet assembly, the CRT display screen is divided into a plurality of zones. A digital memory is provided with a data storage field and a flag bit field at each address. Addresses of the zones are generated by means of a sync signal regenerated from an input video signal. First, the addresses of zones to be subjected to the adjustment of convergence distortion are selected to set flags in the flag bit fields of the digital memory at its addresses specified by the selected zone addresses. Then, by referring to the flags, guide patterns are displayed on the selected zones and are used to adjust the convergence distortions in those zones. Preferably, one of the displayed guide patterns is flickered. Correction data based on the results of the adjustment are stored in the data storage fields of the digital memory at the corresponding addresses. Correction data for zones other than the selected zones may be interpolated from the correction data for the selected zones.

    摘要: Disclosed is an optical switch of the rotary-type in which a pair of opposing optical transmission path mounting members are disposed on the same axis.A plurality of junction faces of optical transmission paths disposed on the respective opposing plane portions of the mounting members along phantom circles which are opposite to each other and concentric with the pair of mounting members respectively with respect to the axis so that the junction faces on the respective plane portions are capable of being correspondingly opposite to each other.When the pair of the mounting members are relatively rotated about the axis, the facing mates of the opposing junction faces of the optical transmission paths are changed over to switch the optical transmission paths.In the case where an optical path relay member is interposed between the pair of the optical transmission path mounting members, the optical transmission paths can be switched by only the rotation of the optical path relay member.

    摘要: A CRT picture display apparatus of the raster scan type comprises a cathode ray tube for raster scanning, a horizontal deflection circuit for supplying a horizontal deflection current to a horizontal deflection coil of the CRT, a vertical deflection circuit for supplying a vertical deflection current to a vertical deflection coil of the CRT, and a display data generator for supplying data to be displayed to the CRT. The horizontal deflection circuit produces as the horizontal deflection current a triangular current having one period which is twice a horizontal scanning period, and the triangular current has a first portion which increases in response to a horizontal sync signal at a predetermined inclination and a second portion which decreases in response to the next horizontal sync signal at the predetermined inclination and continues until the further next horizontal sync signal, whereby the period for a scanning line to proceed from lefthand end to righthand end of a raster on a screen of the CRT is made substantially equal to the period for the next scanning line to proceed from righthand end to lefthand end, and data is displayed during both the periods.
