Title: Image forming device
Inventor: NISHIO TAKEFUMI
IPC: G03G15/01
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To obtain the sufficient amount of data concerning an LDC curve without substantially decreasing image output speed by detecting the potential of the surface of a photoreceptor layer of a toner carrier where a pattern is exposed after electrifying the photoreceptor layer to different potential at the different image non-forming time. SOLUTION: In printing operation for one sheet, initial potential for a photoreceptor respectively suitable to cyan, magenta, yellow and black colors is given to them, and an image is exposed with exposure in accordance with the image data. In a very short time before starting next printing after finishing printing for one sheet, how the potential of the surface of the photoreceptor is changed according to the initial electrification potential and the exposure on the surface of the photoreceptor is examined. The initial electrification potential on the surface of the photoreceptor and the electrification potential in the case of increasing the exposure are measured by a surface potential detection means 232. The electrification potential and the exposure for the next printing are controlled based on the obtained new data on the LDC curve.

Abstract: PURPOSE:To prevent divergence due to miscorrection by inserting a nonlinear circuit not generating an output when an input signal is smaller than a prescribed value, betwen a subtractor subtracting a pseudo echo signal from an input signal at the transmission side and a pseudo echo signal generating circuit. CONSTITUTION:A receiving signal Xn is transmitted to a signal storage circuit 12 at the receiving side. The circuit 12, a tap coefficient storage circuit 14 and a superimposed integrating circuit 15 constitute a transversal filter 16, its output is the pseudo echo signal, and a subtractor 17 cancels echo from a transmission side signal Yn. A residual signal eh being an output of the subtractor 17 is changed into a signal e'n by the nonlinear circuit 19 according to the input/output characteristic as shown in a figure. A tap gain correcting circuit 21 corrects the tap coefficient of the tap coefficient storage circuit 14 by using output signals X(n-1) and en' of the receiving side signal storage circuit 12. A circuit 21 is a pseudo echo signal generating circuit. Thus, when the residual signal en is a prescribed value or belw, the output signal en' of the nonlinear circuit 19 is clamped to zero, and the correction of the tap gain correcting circuit 21 is not performed substantially.

IPC: G02B6/12
Filed: 1993-08-12
Abstract: PURPOSE:To obtain a good propagation characteristic with low loss by preventing the deformation of core waveguides to be generated at the time of sintering porous glass. CONSTITUTION:The core waveguide parts 1a which largely vary in the shrinkage rate of the porous glass at the time of sintering between one side and the other side of the core waveguides 1 are provided with dummy core waveguide parts 6 which prevent the deformation of the core waveguide parts 1a near these parts.

Abstract: PROBLEM TO BE SOLVED: To stably provide a satisfactory image over a long period without deteriorating the transfer performance even by long-term use by providing a surface skin layer consisting of a resin layer whose change of electric resistance is a specified value or lens when exposed to ozone under a specified condition. SOLUTION: A surface skin layer 202 formed on a conductive rubber layer 201 is formed of a resin layer in which the change of electric resistance is 0.5 digits or less when exposed to ozone under the condition of ozone concentration 10 ppm, 35 deg.C and 120 hrs. When the change of electric resistance exceeds 0.5 digits, an image failure is often caused in a long-term use although a satisfactory image is provided in the initial stage, and the effect is insufficient. Examples of the resin material forming the surface skin layer 202 include fluorine resin, urethane resin and the like, and urethane resin is particularly preferably used because it has satisfactory follow-up property to elongation of the conductive rubber layer 201 and is hardly cracked even by long-term use. The urethane resin is preferably mainly composed of a polyester or polyoleftn polyol or the like.
