    摘要: 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.

    摘要: An image processing system contains a plurality of recording units, each for recording an image on a separate recording material, which are coupled together so that a recording material on which an image is recording on a first recording unit is detected and fed to the next recording unit so as to receive a second image from the second unit and thereby form an overlay on a single recording material.

    摘要: A temperature and humidity compensating device is provided in electrophotographic apparatus including a photosensitive medium having a photoconductive layer, an image forming unit for forming an electrostatic latent image on the photosensitive medium, a heat source disposed near the photosensitive medium for heating the latter, a temperature detector disposed remotely from the heat source for detecting the temperature of the photosensitive medium, and control means for controlling the heating of the heat source so that the temperature of the photosensitive medium detected by the detector is not lower than the ambient temperature. Thus, the photosensitive medium may be prevented from deterioration due to falling temperature and moisture absorption, thereby permitting a normal image formation to be achieved.

    摘要: There is disclosed an invention for generating contract information for an image forming apparatus for which the user is going to conclude a contract. The history information of an image forming apparatus used by the user and having a contract history is stored and managed in correlation with the user. Such management is executed in a center server capable communication with the image forming apparatus through a predetermined communication channel. The above-mentioned information includes contract term, machine type, number of print outputs etc. of the image forming apparatus. Also the image forming apparatus to be managed includes that currently contracted and that contracted in the past. In case the user wishes to conclude a new contract for an image forming apparatus, new contract information is generated according to the history information managed by the center server in correlation with the user. This invention provides a system capable of realizing the foregoing.
