摘要:
A photosensitive member for use in an electrophotographic apparatus in which a bias potential is applied to the member during development. The member comprises a conductive support having at least one support edge and a photosensitive layer formed on the surface of the support and extending up to a point substantially coincident with the support edge. A tapered surface is formed at the extremity of the photosensitive layer adjacent to each support edge which extends from the top of the photosensitive layer to the support edge. The maximum angle between a tangent of the tapered surface and the surface of the conductive support is less then 45.degree. thereby preventing an edge effect by which a background smearing in the form of a black band may appear on copied paper obtained. Such a tapered surface can be easily formed through a vaporizing technique with a special masking in accordance with the present invention.

Either a single copy or a plurality of copies of an original document may be made. Making a single copy or the last copy of a plurality of copies comprises, during a first revolution of a photoconductive drum, electrostatically charging the drum, radiating a light image of the document onto the drum to form an electrostatic image, developing the electrostatic image using a magnetic brush to form a toner image, transferring the toner image to a copy sheet, electrostatically discharging the drum and uniformly radiating the drum with light to further discharge the same. During a second revolution of the drum the drum is cleaned with the same magnetic brush to remove residual toner, and again electrostatically discharged and uniformly radiated. During a third revolution of the drum the magnetic brush is again used for cleaning. For making all but the last of a plurality of copies, the drum is charged, imaged, transferred and electrostatically discharged during a first revolution thereof and cleaned with the magnetic bruch during a second revolution. Whether the process is used to make one or more copies, the same portion of the drum is always used. Subsequently, the drum rotation is indexed so that the next process will use a different portion of the drum.

The apparatus is for heat-fixing a toner image onto a support sheet in which the fixing of toner image is effected through both infrared radiation and direct contact with a heated surface of fixing roller in succession. An endless belt, having a transparency for infrared and trained over a pair of rollers, is disposed within a heat insulating casing, an upper run of the belt defining a path of movement of a toner image bearing support sheet to be fixed. An infrared radiator is disposed beneath the upper run of belt while a reflecting plate is disposed at the opposite side of the belt from the radiator with respect to the path. A fixing roller is disposed downstream of the radiator along the path for completing the fixing.

[Problems] To provide a resin composition containing ultrafine silver particles and having excellent antibacterial property as well as excellent deodorizing power against both the nitrogen type smelling components and the sulfur-containing smelling components.[Means for Solution] A resin composition obtained by heating and mixing a resin composition, a silver carboxylate and a carboxylic acid together. A thermoplastic resin, the silver carboxylate and the carboxylic acid are heated and mixed together at a temperature lower than a temperature at which the silver carboxylate starts decomposing but not lower than a melting point of the thermoplastic resin.[Selected Drawing] None
摘要:
The variable displacement gear pump for a loading system in an industrial vehicle has main and sub gear pump portions, suction, discharge and bypass passages, and check and opening valves. The main gear pump portion has main drive and driven gears, and has suction and discharge side spaces. The sub gear pump portion has sub drive and driven gears, and has suction and discharge side spaces. The bypass passage returns hydraulic fluid in the discharge-side space of the sub gear pump portion to the suction passage. The check valve prevents hydraulic fluid in the discharge-side space of the main gear pump portion from flowing to that of the sub gear pump portion. The opening valve is used for opening and closing the bypass passage, and closes the bypass passage due to a pressure in a discharge conduit of the loading system increased by the load applied to the loading system.

A method for producing glycolide, including the steps of: heating a mixture containing a glycolic acid oligomer, a high-boiling point polar organic solvent having a boiling point of 230 to 450° C., and a tin compound under normal pressure or reduced pressure until a temperature at which the glycolic acid oligomer is depolymerized, to thereby dissolve the glycolic acid oligomer in the high-boiling point polar organic solvent; heating a solution, in which the glycolic acid oligomer is dissolved, under normal pressure or reduced pressure until a temperature at which the glycolic acid oligomer is depolymerized, to thereby form glycolide by depolymerization of the glycolic acid oligomer in the solution; and co-distilling off the high-boiling point polar organic solvent and the formed glycolide from a depolymerization reaction system.
