Filed: 1986-08-30
Abstract: PURPOSE:To avoid waste of an operation, and to improve the copying efficiency by executing an image formation in the going path and the returning path, respectively, of a latent image forming unit for scanning on a belt photosensitive body. CONSTITUTION:Transfer paper 7 on which a toner image has been formed is carried to a fixing part 9 by a carrying belt 8, and the toner image is transferred on the transfer paper 7 by a fixing roller. At the time point when the rear end of the transfer paper 7 has been peeled off from a belt photosensitive body 1, the belt photosensitive body 1 is stopped again. Simultaneously, a latent image forming unit 2 which has been brought to holding moves in the direction as indicated with an arrow E, and on the belt photosensitive body 1, an electrostatic latent image corresponding to an original image is formed. As for this latent image formation in the going path, a second main electrification charger 24 functions. At the time point when the latent image forming unit 2 has ended to scan the original in the returning path and has returned to a home position H, the belt photosensitive body 1 is turned, and given to the same copying process. Simultaneously, the latent image forming unit is stopped at a spot H. By executing repeatedly this operation, copies of two sheets each are obtained in the going and returning paths of the latent image forming units 2, and a copying machine of a high speed is obtained.

IPC: G03G15/08
Filed: 1994-08-05
Abstract: PURPOSE:To prevent the flowing out of liquid toner to the side of a developing unit by preventing a supplying unit from being moved to connect to the developing unit while the toner replenished to the supplying unit is liquefied at a position away from the developing unit.

Title: Perpendicular magnetic recording and reproducing head
Inventor: MIZUNO MASANOBU
IPC: G11B5/127
Filed: 1987-08-18
Abstract: PURPOSE:To use a high-sensitivity main magnetic pole of large magnetic saturation and to simultaneously obtain a perpendicular magnetic recording head having high recording and reproduction resolving power by forming a thin film of a superconductive material having a gap consisting of a high permeability magnetic material to the sliding surface of a single magnetic pole head for perpendicular magnetic recording.

The magnetic flux of the excited main magnetic pole 3 is passed concentrically through the magnetic material formed in the gap part by the Meissner effect of the superconductive material on the head-sliding surface so that the magnetic recording medium 6 is strongly and sharply magnetized near the gap part at the time of recording. The peripheral magnetic field is shielded by the Meissner effect of the thin superconductive material film and only the magnetic field of the magnetic recording medium 6 existing near the gap is passed to the main magnetic pole 3 side. The head which allows the strong and sharp perpendicular magnetization and has the high resolving power simultaneously is thereby obtd.
