Title: Color image forming device
Inventor: SAKAUCHI KAZUNORI
IPC: G03G15/01
Filed: 1990-03-15
Abstract: PURPOSE:To obtain a picture without density unevenness by forming alternating charge density patterns on the entire surface of a transfer paper carrying means corresponding to transfer paper at the time of each color transfer stage. CONSTITUTION:A charge pattern forming electrode roller 22, whose opposite electrode is a roller 18, is made abut on a transfer belt 17 wound around the driving belt roller 18, and this electrode roller 22 is connected to an AC power source 23. On the other hand, a charge pattern forming electrode roller 22A, whose opposite electrode is a roller 19, is made abut on the transfer belt 17 wound around the follower belt roller 19, and this electrode roller 22A is connected to an AC power source 23A. Since the negative and positive charge density patterns are formed on the transfer belt 17 corresponding to the transfer paper at the time of the transfer stage, the comparative position of the transfer paper is not deviated from that of the transfer belt 17. Thus, transfer efficiency is made entirely uniform and a preferable picture without density unevenness can be obtained.

Title: File exchange system for real time data processing system
Inventor: SAKURAI YASUO
IPC: H04Q3/545
Filed: 1983-04-15
Abstract: PURPOSE:To avoid an interruption of a system operation during a file exchange by applying previously the initialization to a call which is set under a non-relief state. CONSTITUTION:When a new file is loaded to a memory 14 of a spare system, a new file is set on the memory 14 for call processing. Then the initialization is applied to the area of new call information NCD25. Hereafter a control processor 11 performs the normal call processing and at the same time converts the call information CD21 of an old file into the corresponding information NCD25 in an idle time with use of a new/old call information conversion table 23. The information NCD25 is loaded to an idle area of a memory 13. In case the state of the call is shifted to a relief state during the normal call processing, the information NCD25 is set in a relief state. While the initialization is applied to the NCD25 in a relief state when the relief state is shifted to a non-relief state. Thus an old file is switched to a new file.
