IPC: G03G15/00
Filed: 1989-03-17
Abstract: PURPOSE:To avert the generation of a toner splashing and the increase in the burden of a cleaning part and to eliminate the influence on the image formation after a jam treatment so as to prevent the degradation in image quality by providing a backward rotation control mechanism which drives various developing members of a developing device in a backward direction in accordance with the detection of a jam state in a paper feed passage. CONSTITUTION:The backward rotation control mechanism 156 which drives the various developing members of the developing device in accordance with the jam detection signal from a jam detecting means 150 is provided. Namely, the various developing members of the developing device are driven in the backward direction by the backward rotation control mechanism 156 and the toner remaining on a developer carrier is successively returned into the developing device when transfer paper jams in the paper feed passage. There is no more toner in the developing region in this state and the toner is not supplied from the developing device to the electrostatic latent image remaining on a latent image carrier. The transfer and adhesion of the fresh toner onto the latent image carrier do not arise. The generation of the toner splashing in the jam state and the increase in the burden of the cleaning part are averted and the image formation after the jam is well executed.

IPC: G02F1/1333
Filed: 1986-03-24
Abstract: PURPOSE:To prevent almost completely the lowering of visibility due to a light reflaction of a display surface by using a thin film composed of polyvinyl butyral resin which has almost the same extent of the refractive index to those of a glass substrate and a polarizing plate, and has a less tendency for generating light absorption at the visible ray range as an intermediate film. CONSTITUTION:The thin film of the polyvinyl butyral resin which has almost the same extent of the refractive index to that of the transparent glass substrate and does not display almost light absorption at the visible ray range is used as the intermediate film 2. The glass plate 1 which is effected an anti-reflection treatment by etching, vacuum-depositing, or sputtering, is stuck directly on an upper surface of a glass substrate 4 placed in the upper side of the titled device or the polarizing plate 3 by means of a vacuum-thermocompression bonding method to form the most outer surface of the terminal display device. Thus, the surface reflaction does not occur. Further, since any air layer does not present in the inside of the titled device, the refractive indexes of a glass, a butyral resin and a polarizing plate are closely with each other, the surface reflaction and the back reflaction in the inside of the titled device are remarkably reduced.

Filed: 1981-04-30
Abstract: PURPOSE:To form fine pattern with good coverage accurately by a method wherein a smooth thin film of setting type coating substance is formed on the surface of an Al thin film and the pattern is formed on this thin film by photo- etching. CONSTITUTION:Al is deposited on an Si substrate 1 while the substrate 1 is heated and an Al thin film 3 is formed with good coverage. Then a film 4 is formed by coating the thin film 3 with setting type coating substance so as to make the surface smooth. Then a thin film 5 of light reflecting material or light absorbing material is formed on the film 4. Then the thin film 5 is coated with photoresistor and the pattern corresponding to the required masking is formed  on the thin film 5 by photo-lithographic method. As the thin film 5 does not give the light diffused reflection, the pattern which corresponds to the masking  very accurately can be formed. Then the thin film 4 and 3 are selectively removed by using the thin film 5 as a mask. With the this constitution, fine pattern with good coverage can be formed accurately even on a substrate with uneven surface.
