Title: Winding device of photoreceptor
Inventor: YAMAGUCHI TOMOYUKI
IPC: G03B27/32
Filed: 1979-06-27
Abstract: PURPOSE:To smoothly wind a photoreceptor, eliminate its creasing and waving and prevent the unevenness and drop-out of copied images by making the inner side of the side plates at both end parts of a winding pipe to a convex form and  supporting these side plates by a pair of drum-form rollers. CONSTITUTION:Turn rollers 11 and a winding pipe 14 are disposed next to a transfer drum 8. Side plates 15 which are made centrally tall at the face on the mutually opposing in side are provided to the two end parts of the winding pipe 14. These side plates 15 are supported by a pair of rollers 16 having a concaved surface and  one of them is driven. As a result of this, even if a photoreceptor 4 comes zigzag, it is led to the curved faces of the side plates 15 and is wound in the correct winding position, thus telescoping of the end faces does not occur. Since the rollers 16 are just supported by said concaved surface, they do not restrain lateral movement and  therefore the photoreceptor 4 returns automatically to the central part of the drum,  thus it is kept free from any undue stress and does not cause creasing either. This  makes it possible to correctly wind the photoreceptor 4.

CONSTITUTION:The rotating direction of a pressure attaching roller 5 is the same direction as that of a developing sleeve 1, therefore, the surfaces of both of them are attached by pressure in a contact part C and moved in the opposite directions, and as the pressure attaching roller 5 rotates, a carried toner is inserted and pressed between both the surfaces and brought to a frictional electrification, becomes a toner layer of a mode-rate thickness and adheres to the surface of the developing sleeve 1. Subsequently, the layer thickness is controlled by a doctor blade 7, and the toner thin layer to which a sufficient charge has been electrified is carried by the surface of the developing sleeve 1 and carried, supplied stably to an electrostatic latent image which has been formed on a belt 8, and it is converted uniformly to a visible image. In the downstream side of a developing area D, a residual toner whose unnecessary charge has been eliminated by a destaticizing brush 9 is destaticized and scraped down by the pressure attaching roller 5 moving in the direction opposite to the surface of the developing sleeve 1. In this way, the generation of an image failure caused by a residual developer can be prevented.

Title: Insulating oil deterioration sensing device
Inventor: ISHICHI TORU
IPC: G01N27/416
Filed: 1991-03-19
Abstract: PURPOSE:To selectively sense the acetilene contained in an insulating oil. CONSTITUTION:At a window 3 installed in the wall surface of a vessel 2 a working electrode 4 is furnished, in which a metal 4b is formed on a diaphragm 4a consisting of a porous insulative film, while a reference electrode 7 is arranged at a window 5 installed in the other side wall surface, and therein dilute sulfuric acid is accommodated as an electrolyte 8. By a constant voltage circuit 10 a potential is impressed between these working electrode 4 and reference electrode 7, which is higher than the oxidating potential than acetylene and lower than the oxidating potential of ethylene. The acetylene having passed through the diaphragm 4a is oxidated and generates an oxidative current between the electrodes which is proportioned to the concentration. No electrolytic current will be generated even though ethylene passes the diaphragm 4a. Hydrogen, ethane, methane, CO, and CO2 are also contained in insulating oil, but a gas sensor 1 of constant voltage electrolysis type exhibits a very low sensitivity to these components, and therefore the acetylene in the insulating oil can be sensed with high sensitivity as long as the ethylene sensitivity is set low relative to the acetylene.
