    摘要： Transmission line groups consisting of a plurality of loop-like transmission routes (1...5, 10...50, 100...500) are mutually connected via transmission controllers and are arranged in a two- or three-dimensional space. Processing units are thus connected as a homogeneous network in matrix or mesh form by means of the loop-like transmission routes. The transmission controllers corresponding to the nodes (11...51) of the network have a communication management function such that they send the data without grasping the situation on the transmission routes, independently check the trouble between the adjacent transmission controllers, and specify the position of trouble. A communication network system such as a high local area network (LAN) or the like can be realized.

    摘要： A machine tool controlling subsystem for use with a distribut­ed system comprises a plurality of such subsystems (11, 21, 41; 12, 22, 42...1n, 2n, 4n), each of which includes a machine tool, and a transmission medium (30) operatively associated with said subsystems for transmitting information to said sub­systems. Each subsystem includes means (11, 12...1n) for in­dependently determining whether or not the machine tool is operated based on the received information from said trans­mission medium, and means (41, 42...4n) for operating said machine tool based on the determination of said independently determining means.

    摘要： According to the present invention, a file recovery system is provided in which the commands for recovering files such as a historical file are unnecessitated and the recovery system configuration is independent of the host processing system. That is, since the equipment (12) for achieving a file recovery does not have an information about the location of the recovery data, an information about the content of a file to be recovered is transmitted to a transmission line (1). The other equipments (12) asynchronously receive the information and judges whether or not a file containing the same file exists in the own system. If the file exists, the content of the file is transmitted to the transmission line (1). The equipment (12) achieving the file recovery asynchronously receives from the transmission line (1) the file data of files such as a historical file and establishes data consistency by use of the buffered current data (504) and the event number (1004), thereby recovering files such as a historical file.

    摘要： In a distributed processing system which distributively performs a series of processes for a work at a plurality of processing units (2i) connected to a common transmission path (3) and having a circuit (2i, 1i) for transmitting information from a processing unit to the common transmission path, a circuit (2i, 1i) for receiving from the common transmission path the information required for the processing of a program stored in each processing unit, and a circuit (2i, 1i) for detecting if all the information required for the processing of the program has been collected, performing the processing of the program using the collected information as input information for the processing and transmitting the processed result data to the common transmission path, a method of managing programs includes the steps of: transmitting a program stored in each processing unit or a program newly generated or modified by each processing unit, together with program generation information, to the common transmission path; and discriminating a difference between generations of a plurality of developed programs.
