IPC: F04C15/00
Filed: 1980-06-04
Abstract: PURPOSE: To prolong the service life of a pump by forming a jacket for fluid along the outside wall of a drum and by fastening a vane to the other end of an input shaft and by providing a cooling device which forms a water pump and cooling a pumping tube.  
     CONSTITUTION: A cylindrical drum 1 forms a jacket 1a which has a proper sectional area along the outside wall which contacts a tube inside. A flow inlet nozzle 1b and a flow outlet nozzle 1c are provided on the lower part of the wall and the upper part of the wall. A water pump is constituted by forming a casing 1e, having a suction nozzle 1d, which is integrated with a drum 1, and which covers a vane fastened to an end 5b of an reactionary input shaft 5a of a rotary shaft 5. At the same time when an arm 6 rotates through the rotary shaft 5 and performs pumping action, the vane 11 also rotates and starts the action of the water pump. The cold water sucked up from the suction nozzle 1d enters a jacket 1a through the flow inlet nozzle 1b and cools a tube 3, thereby prolonging the service life of the pump.

Title: Optical recording device
Inventor: KATAOKA KEIJI
IPC: B41J2/44
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a highly precise optical recording device where an error hardly occurs in an interval between the scanning lines of multibeams even if an arrangement error of a photosensitive drum occurs by crossing the main beams of multibeams on the more scanning lens side than a rotary polygonal mirror position in an auxiliary scanning direction. SOLUTION: In the position of the reflection face 5 of a rotary polygonal mirror, the parallel beams of multibeams cross one another. Namely, the main beams of the multibeams in a meridional direction cross in a rotary polygonal mirror position. Thus, the size of the rotary polygonal mirror can be similar to the case when only one beam exists even if the multibeams are used. The multibeams deflected in the rotary polygonal mirror are converged on a photosensitive drum 7. When the optical system is used, the main beams of the multibeams emitted from the scanning lens move in parallel to an optical axis against an auxiliary scanning direction. Even if an arrangement error occurs in the photosensitive drum 7, the interval of the scanning lines which the multibeams form is difficult to be fluctuated.
