Inventor: SAKAI TETSUYA
IPC: F16C13/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To obtain a stable transfer characteristic by using a specified transfer roller. SOLUTION: In this image forming device where a toner image formed on an image carrier is transferred to a recording medium by transfer rollers 46 and 59, a foaming roller is used as the transfer rollers 46 and 59. The absolute value of a value (log R)/ΔV [(log Ω)/kV] showing the voltage dependency of the resistance of the foaming roller is set to <=0.5. The resistance of the foaming roller means resistance between the metallic center shaft of the foaming roller and the entire surface of the foaming roller. In the case the value (Δlog R)/ΔV showing the resistance of the rollers 46 and 59 is <=0.5, a current does not more easily flow even when the current flows, and uniform discharge is generated at a paper non-passing part where the rollers 46 and 59 directly come in contact with an intermediate transfer belt 41.  Therefore, the discharge does not become locally storing, the belt 41 is not deteriorated, and size memory is not caused.

Title: Electrophotographic method
Inventor: NAKABAYASHI WATARU
IPC: G03G15/00
Filed: 1988-11-18
Abstract: PURPOSE:To stably obtain a picture of preferable picture quality even when temperature fluctuates by varying the potential of a base body of a photosensitive body with respect to the earth potential in response to the temperature change of the photosensitive body, and maintaining a surface potential at a fixed value after light irradiation. CONSTITUTION:The potential of the base body 4 of a photosensitive body 1 is varied with respect to the earth potential in response to the temperature change of the photosensitive body 1 thereby maintaining the surface potential at the fixed value after the light irradiation, and thus, the characteristic fluctuation of the photosensitive body 1 is corrected. A voltage of polarity in response to the temperature of the conductive base body 4 of the photosensitive body 1 is directly impressed thereon, therefore the polarity of the voltage impressed on the conductive base body 4 is determined by whether the temperature of the photosensitive body 1 is higher or lower than the reference temperature. Thus, even when the temperature of the photosensitive body 1 fluctuates, a picture of preferable picture quality can be always stably obtained.

IPC: H01L21/84
Filed: 1988-11-17
Abstract: PURPOSE:To eliminate imbalance of characteristics caused by the uniform thickness of a P-channel region and an N-channel region by nonuniformizing the thicknesses of channel regions of a P-channel transistor and an N-channel transistor. CONSTITUTION:After, e.g., N<-> poly Si is deposited on a transparent quartz glass substrate 1, and an island type active layer 2 is formed, silicon nitride is deposited on the whole surface, and a silicon nitride film 10, in which a portion corresponding to a channel region on one side active layer 2 is lacked, is formed. By thermally oxidizing the substrate, an SiO2 oxide film 6' is formed on the lacked part of the silicon nitride film 10. The silicon nitride film 10 is etched and eliminated. At this time, the SiO2 oxide layer 6, is simultaneously etched, but a part of the oxide layer is left after the silicon nitride film is eliminated, because the etching speed of the silicon nitride film differs from that of the SiO2 oxide layer. The thickness of oxide film of the residual oxide layer is adjusted by, e.g., processing time and processing temperature at the time of oxidizing. Thereby, the thickness of the channel region 5 of the N- channel transistor can be made thinner than the P-channel transistor.
