Title: Image forming device
Inventor: IKESUE TATSUYA
IPC: G03G15/043
Filed: 1988-04-28
Abstract: PURPOSE:To obtain a sharp image in which sensitivity can be improved and fogging is prevented from being generated by forming an electrostatic latent image on the image carrier of an organic photoconductor to be electrified to a positive value by image exposing stage, and applying whole image exposure on a stage between an image exposure stage and a developing stage at the time of developing the electrostatic latent image by the developing stroke. CONSTITUTION:The electrostatic latent image is formed on the photosensitive drum 1 of the organic photoconductor 1a to be electrified to the positive value by the image exposure stroke, and at the time of developing the electrostatic latent image by the developing stage, the whole image exposure is applied on the surface of the organic photoconductor 1a at the stage between the image exposure stroke and the developing stage by an exposure means 3. Thereby, an electric charge remaining in the neighborhood of the boundary of the electric charge generating layer and the electric charge migrating layer of the organic photoconductor 1a is moved to a substrate side, and ground potential is decreased, and the sensitivity of a 1/10 exposure quantity can be increased. In such a way, it is possible to prevent the fogging due to the splash of a developer 5a from being generated, and to form a satisfactory image.

Title: Production of one side zinc plated steel plate
Inventor: KAJI MAKOTO
IPC: C23C2/22
Filed: 1981-07-07
Abstract: PURPOSE:To produce a one side zinc plated steel plate having little residual zinc on the ground side by carrying out zinc hot dipping by the use of a bright finished steel plate of small surface roughness then grinding one surface thereof thereby removing the zinc. CONSTITUTION:The bright steel plate of <=5mu, more preferably about <=2mu Rmax surface roughness obtained by controlling the roughness and transfer rate of finishing rolls in the cold rolling or skin pass rolling state is carried out with zinc hot dipping then the plating layer on one side is ground with grinding rolls or grinding belts pressed thereto, whereby it is removed of the zinc. Since the surface roughness of the steel plate is made small, the residual zinc owing to the ruggedness on the surface of the steel plate is reduced. Also, the plating thickness can be controlled thin, the grinding is extremely easy, the electric current for pressing the grinding wheels or grinding belts is less required and the wear of the grinding rolls or grinding belts is reduced considerably.

IPC: G09G5/36
Filed: 1992-04-27
Abstract: PURPOSE:To prevent the overtaking a plotting by a display and the occurence of defective image by making a display selecting signal effective only when the counter value of a counter circuit set beforehand is decremented every time a plot controlling signal is made active and an output signal from the counter circuit is made active. CONSTITUTION:Plotting data and a plotting address outputted from a plotting circuit 2 are inputted to a selector circuit 6 via a plotting selector circuit 4 and outputted to a second VRAM 8. At a counter circuit 9, a presetting is made at a specified set value by a plot selector signal outputted at the time when the plotting of one frame is finished. The count value of this counter circuit 9 is decremented every time the plot controlling signal is inputted and when this value becomes 0, the output of the counter circuit 9 is kept active untill next PR signal is inputted. Thus, even when a display rate for one frame is faster than a plotting frame, the overtaking of the plotting by the display is eliminated.
