Title: Gamma correcting device
Inventor: KOIKE KAZUMASA
IPC: G06T5/00
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To execute gamma correction only by the arithmetic circuit of multi- valued digital data by executing a specified operation. SOLUTION: A gamma part 2 is the digital arithmetic circuit and executes gamma correction as against multi-valued picture data which is generated in an input part 1. In the gamma part 2, the operation of an expression: y=x+ i.(MAX/2-|MAX/2-x|) is executed. Wherein followings are adopted. x is input data, MAX is the max. value of input data, y is correction data and i is a conversion frequency. The setting of the conversion frequency (i) is constited so as to be optionally executed from an inpu/display means (for example, a control panel constituted of a display equipment, tenkeys and a switch, etc.) or to be executed to be programmable in a host device. It may be adopted that setting is executed at the time of assembling a device.  Thus, gamma correction is executed only by the arithmetic circuit of multi-vauved digital data without using a RAM look-up table, so that a cost is reduced.

Abstract: PURPOSE:To inhibit the formation of projections on the surface of a vacuum deposited layer and to improve the matchability of the resulting receptor with an electrophotographic copier, by working the metallic surface of an electrically conductive support by the vibration and sliding of a grindstone so as to regulate the surface roughness to a specified value. CONSTITUTION:The metallic surface of an electrically conductive support of Al, stainless steel or the like is ground by sliding a grindstone having a grain size by which the surface roughness Rs can be regulated to 0.05-0.3mum along the surface of the support while vibrating the grindstone. The surface of the support ground by the super-finishing method has a complex shape composed of grinding loci crossing each other, and the bonding strength of the surface to a vacuum-deposited layer is remarkably improved. Se or an Se material such as an Se-Te alloy or As2Se3 is vacuum-deposited on the support to about 40-80mum thickness by a conventional method. The formation of projections on the surface of the resulting Se receptor using the support having 0.05-<0.3mum surface roughness is reduced to such a degree that projections are allowable with respect to the matching of the receptor with an electrophotographic copier.

Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an intermediate transfer belt from hardly coming off. SOLUTION: In the process of producing the intermediate transfer belt 91, it is produced in a state where an inner peripheral side is turned outward, at the beginning and finally tuned inside out, so that the intermediate transfer belt 91 is completed. Coming off occurs because strain remains on a rib 92, at the time of turning the belt 91 inside out. Therefore, notches 93 are provided in the respective places of the rib 92, so as not to exert an excess stress thereon, at the time of turning the belt 91 inside out. When very small holes are provided on the inner peripheral side of the rib 92, the same effect can be obtained as well. Further, when the belt 91 is turned inside out and then, the rib 92 is heated to remove the strain, the same effect can be obtained as well.
