    • A printing or copying apparatus including a rotatable member, a number of processing devices for forming an electrostatic latent image on the rotatable member, for developing the latent image and for transferring the developed image from the rotatable member to an image transfer medium, a circuit for generating a series of clock signals in response to the rotation of the rotatable member, an element for repetitively generating control pulses in each process in accordance with the clock pulses, the control pulses determining the timing with which the processing devices are operated, and a controller for controlling desired operations of the processing devices in accordance with necessary ones of the control pulses. The apparatus includes control elements for processing elements to produce a set number of repeated images on transfer mediums from a single primary image formed on the rotatable member, and for retaining the primary image during an interruption for use in producing the set number of repeated images on resumption of operation.

    • A diagnostic program determines whether the machine is in a proper or improper operational state, and the scanning device is moved to a predetermined position in response to the positioning program after the entry of the key inputs by the entry program, and a copying operation is then enabled. The key entry program is executed after the machine starts, and the positioning program is executed before the start of the scanning device and after the key input entry, wherein the scan is inhibited from exposing the recording medium when the diagnostic program determines that the state of the machine is improper, or when the positioning program determines that the scanning device is not in the predetermined position. Also, the scan is enabled for exposing the recording medium when the diagnostic program determines that the state of the machine is proper and the positioning program determines that the scanning device is in the predetermined position.

    • In a data base processing method including a central processing unit for analyzing a plurality of queries made from a plurality of users so as to determine an internal processing procedure with respect to a data base, and for performing the internal processing procedure; a secondary storage for storing data capable of being shared by each user; and, an input/output controlling processing unit including at least one cache storage, for controlling a transfer of a plurality of records which are required for input/output processing operations between the central processing unit and secondary storage. The data base processing method is featured in that a decision is made whether or not a prefetching operation is carried out at a start of an input/output processing operation by judging the internal processing procedure which has been formed by the query; a retrieval range into which a record to be fetched has been stored is formed when the prefetching operation is performed; and, a prefetching record number is determined as an input/output processing demand unit, taking account of an access characteristic of the internal processing procedure and also a system characteristic containing a size of the cache storage, a performance, of the central processing unit, and a traffic of the input/output processing unit.
    • 一种数据库处理方法,包括:中央处理单元,用于分析从多个用户进行的多个查询,以便确定相对于数据库的内部处理过程,并用于执行内部处理过程; 用于存储能够被每个用户共享的数据的辅助存储器; 以及输入/输出控制处理单元,其包括至少一个高速缓存存储器,用于控制中央处理单元和辅助存储器之间的输入/输出处理操作所需的多个记录的传送。 数据库处理方法的特征在于,通过判断由查询形成的内部处理过程,判定在输入/输出处理操作开始时是否执行预取操作; 当执行预取操作时,形成已经存储了要获取的记录的检索范围; 并且,考虑到内部处理过程的访问特性以及包含高速缓冲存储器的大小,中央处理单元的性能的系统特性,将预取记录号确定为输入/输出处理需求单元, 以及输入/输出处理单元的流量。
