Title: Image forming device
Inventor: WATANABE TOSHIBUMI
IPC: G03G15/08
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which prevents an irregularity in density irrespective of density distribution in an image by replenishing a developing unit with toner according to a place and timing where toner is consumed. SOLUTION: Six replenishment motors 71-76 are provided in the direction of the length of a toner hopper 77, density distribution data is created in a control system by histogram processing image data, and the length of time that the replenishment motors 71-76 individually rotate with the replenishment timing of six delay timers incorporated in a CPU is determined according to the density distribution data. To the developing unit 70, particularly to an area where much toner is consumed, much toner is added with the corresponding timing, therefore irregularity in the toner concentration of the developer does not occur, and even in the case an image having a notable irregularity in density is copied, degradation of image quality due to the irregularity in density hardly occurs.

Title: Fault-point locating method for line having branch line
Inventor: MIYAMOTO TOSHIHARU
IPC: H02H3/26
Filed: 1993-01-18
Abstract: PURPOSE:To make it possible to judge whether a fault point is in a branch line section or out of the section by providing current detecting parts at both terminating parts of a main transmission/distribution line and the branching part and the terminating part of a branch line, and comparing the polarities of the surge currents detected at both detecting parts. CONSTITUTION:The current signals, which are detected with current detecting parts 7-10, are amplified 11 and inputted into a polarity comparing circuit 12 and a time-difference counter 13. In a CPU 14, at first, the polarities of the first waves of the surge currents detected with the current detecting parts 9 and 10, which are arranged at a branching part 5 and a branch-like terminating part 6 of a branch line 4, are compared, and it is judged that the fault has occurred in the section (outside the section) of the branch line 4 when the polarities are reverse (same). The difference between the arriving times of the surge currents to the detecting parts 9 and 10 is measured. Thus, the distance to the fault point is determined. When it is judged that the fault has occurred at the outside of the section of the line 4, the polarities of the first waves of the surge currents detected with the current detecting parts 7 and 8, which are arranged at the main-line terminating parts 2 and 3 of a main transmission/distribution line 1, are compared. When the polarities are reverse (same), it is judged that the fault has occurred in the line 1 (outside the line 1).
