    摘要: A distributed data processing system is provided in which two computers, each running under a different operating system, are coupled so that jobs initiated by a first one of the computers can be executed on a second computer by using the resources of the second computer. This enables the user of the first computer to use the second computer under the environment of the first computer. The first computer acts as the interface between the user and the data processing system. Service programs running on the system can handle or provide for input/output operations during the execution of jobs on the second computer so that the jobs seem to the user of the first computer to be executed on the first computer. The system has means for creating a dummy file in the file system of one operating system which is used as a place holder for a corresponding file in a storage device attached to the other operating system, and accessed by programs controlled by that other operating system.

    摘要: The invention provides a discharging method by which charge can be removed readily, uniformly and efficiently from a surface of a working object even where the surface has a complicated charge pattern of a large number of small positive and negative charged portions present closely to each other at random in a mixed condition. A working object is passed between a positive and negative ion producing discharging electrode and an ion attracting electrode opposed to the positive and negative ion producing discharging electrode and having a face extending in a travelling direction of the working object and a perpendicular direction. During such passage, high positive and negative voltages are applied alternately to the positive and negative ion producing discharging electrode to alternately produce positive and negative ions. Simultaneously, a high ac voltage is applied to the ion attracting electrode to induce positive and negative potentials in the working object so as to attract the positive and negative ions produced by the positive and negative ion producing discharging electrode by the induced potentials of the working object.
