摘要:
This invention provides a rolling mill and a rolling-mill train which are compact. Reducers to be coupled with them can be made compact. The inner surfaces of pipes to be rolled with the rolling mill and the rolling-mill train can be prevented from becoming squarish. The rolling mill comprises a plurality of rolls disposed symmetrically around the pathline of the rolling mill, an annular driving bevel gear of a large diameter for driving and rotating the rolls, an input-shaft mechanism for rotating the driving bevel gear, a plurality of transmission mechanisms disposed at regular intervals along the driving bevel gear, and a housing for holding them. The input-shaft mechanism (i) has an input shaft inserted in the housing from its outside and an input bevel gear of a small diameter mounted on the input shaft and engaging with the driving bevel gear and (ii) is disposed between two adjacent transmission mechanisms. With the input shaft disposed horizontally, the phase angle of the roll unit can be adjusted minutely.

摘要:
A sheet feeding and separating device incorporated in image forming equipment for feeding sheets one by one from a sheet stack while preventing two or more sheets from being fed together as far as possible and, when a plurality of sheets are accidentally fed together, surely separating one of them from the others. A pick-up member is implemented as an endless dielectric belt. An AC power source forms a charge pattern on the belt via an electrode. As a result, the belt retains a sheet by attraction and transports it due to the Maxwell stress generated in the sheet. When a plurality of sheets are fed together, an arresting member which faces the belt separates one of them from the others. Alternatively, a charge pattern may be formed on the surface of the arresting member.

The present invention provides an electrostatographic apparatus having a control circuit (35) which controls an optical unit (5) to scan a photoconductor (1) during a predetermined time period with laser beam lit irrespective of recording signals after stoppage of power supply from a power source (34) to a charger (2) and a developer (7), thereby lowering potential on a surface of the photoconductor (1) after the stoppage of power supply.
摘要:
In order to allow the surgical operator and his assistant to make stereoscopic viewing of the region of surgery with a same magnification and in coaxial relationship, the surgical microscope comprises: a common objective lens; a pair of variable magnification optical systems disposed on the image side of the objective lens; and a pair of light beam splitting members disposed on the image side of the pair of variable magnification optical systems, respectively, wherein arrangement is provided so that paired observational optical paths are to be directed to extend respectively in a plurality of directions each having a predetermined angle relative to a plane containing the optical axes of the pair of variable magnification optical systems, within a plane crossing these optical axes at right angles, respectively. The pair of light beam splitting members are constituted as an optical path splitting unit, and the barrel section and the optical path splitting unit are removably coupled to each other.
