A cold formation method of composite silver nanoparticles has been established. Thus, provided are composite silver nanoparticles comprising a silver core, which is made up of aggregated silver atoms and has an average particle diameter of from 1 to 20 nm, and an organic coating layer formed thereon which comprises at least one member selected from an alcohol molecule derivative having 1 to 12 carbon atoms, an alcohol molecule residue or an alcohol molecule; a composite silver nanopaste which contains at least the composite silver nanoparticles and a solvent and/or a viscosity grant agent added thereto; a method of producing the same; an apparatus for producing the same; a method of bonding the same; and a method of patterning the same. The method of producing the composite silver nanoparticles comprising mixing silver salt microparticles with an alcohol solvent in excess to prepare an excess alcoholic solution, reacting the solution in a reaction chamber for a predetermined period of time at a predetermined temperature, and thus forming silver cores from the silver salt at a low temperature by the reducing effect of the alcohol and also forming an organic coating layer derived from the above-described alcohol around the silver cores.

摘要:
A sheet processing apparatus including a stacking portion for stacking sheets, an alignment reference wall disposed in approximately parallel with a conveying direction of the sheet, an alignment moving wall for performing alignment by making an end portion of the sheet hit with the alignment reference wall, a processing mechanical section for carrying out binding with respect to the sheet bundle thus aligned, and a plurality of rotating pairs disposed in a widthwise direction approximately perpendicular to the conveying direction of the sheet for conveying the sheet bundle in a pinching manner. The sheet processing apparatus is capable of performing a process such as binding in the processing mechanical section after the sheet bundle which has been aligned by the alignment reference wall and the alignment moving wall is conveyed by a predetermined distance by the rotating pairs, and it is characterized in that each of the plurality of the rotating pairs disposed in the sheet widthwise direction has a pressure different from that of other rotating pairs for pinching the sheet.

A discharged sheet stacking apparatus includes a sheet feed-in device for pinching and feeding a sheet onto a sheet stacking portion on which a plurality of sheets are stacked and for causing a tip end of the sheet to abut against a sheet stopper. The sheet feed in device is disposed at a position spaced apart from the sheet stopper by a distance smaller than a length of the sheet. The sheet feed-in device continues the feeding operation while pinching a tail end of the sheet even after the tip end of the sheet abuts against the sheet stopper so that, after a loop is formed in the tail end of the sheet, the sheet is discharged onto the sheet stacking portion.

A process cartridge detachably mountable within an image forming system, including an image bearing member, a processing device for acting on the image bearing member, a housing for supporting the image bearing member and the processing device, and a cover shiftable between a protecting position where the image bearing member is protected and a retard position where the cover is retarded from the protecting position. The cover is spaced apart from the housing at least in the retard position and contacts a housing guide member. An image forming system includes a mounting device for mounting such a process cartridge, an air flow generating device for generating an air flow passing between the housing guide member and the cover, a transfer device for transferring a developed image formed on the image bearing member onto a recording medium, and a conveying device for conveying the recording medium.
摘要:
An optical scanning apparatus can record image information in a plurality of resolutions by changing the pitch (scanning interval) of light beams in a direction orthogonal to the scanning direction. In the apparatus, a plurality of light beams emitted from a light-source unit having a plurality of light-emitting portions are guided to a deflector via an optical system, and are deflected and reflected by the deflector. The light beams are then guided to a surface to be scanned via an imaging unit, so that the surface is simutaneously scanned by the plurality of light beams. At that time, an angle .theta. between a first line connecting imaged positions of the plurality of light beams on the surface and a second line obtained by the scanning line of the light beams in the scanning direction on the surface, can be changed by an angle adjusting unit.
