Title: Electrophotographic sensitive body
Inventor: UMEDA MINORU
IPC: G03G5/09
Filed: 1987-03-09
Abstract: PURPOSE:To enhance sensitivity and to lessen the degradation in electric chargeability arising from pre-exposing fatigue by incorporating polypropylene glycol monoether into a layer in which an electric charge generating material is dispersed. CONSTITUTION:An electric charge generating layer 1 and charge transfer layer 2 are successively laminated on a conductive base 3. The polypropylene glycol monoether is incorporated into the layer 1 in which the charge generating layer is dispersed. Namely, the polypropylene glycol monoether is chemically adsorbed in the charge generating material and provides the recombination center of the charges generated by light absorption and, therefore, the charges generated by the pre-exposing fatigue are quickly recombined and are thereby annihilated, conceivably by which the drop of the charge potential of the photosensitive body is suppressed. The electrophotographic sensitive body which has the high sensitivity, extremely lessens the degradation in the electric chargeability arising from the pre-exposing fatigue and obviates the drop of the charge potential even after repetition of the electrical charging and exposure is thereby obtd.

Title: Manufacture of duplicating magnetic playback medium, duplicating device for above manufacture and magnetic duplicating head
Inventor: DUURLAND JOZEF MARIA
IPC: G11B15/43
Filed: 1993-03-16
Abstract: PURPOSE: To transfer a signal at a high speed tape transferring speed by increasing a tape tension and also making a distance between the centers of a conversion gap shorter than those of a reproducing head. CONSTITUTION: With a tape 1 travelling in the direction of the arrow on the head surface 7 of a duplicating head 2 during duplication, the tape 1 is held on the duplicating device 4 at a tension higher than an ordinary tension at the time of reproducing the signal already recorded in an DCC recording and reproducing device. In addition, with a space between conversion gaps 5 made shorter than the one between the centers of a reproducing head, tracks are separated after duplication even with a higher tension of the tape 1; therefore, the separation of the tracks are corrected even with the tension of the tape 1 increased. Thus, contraction is eliminated in the transverse direction of the tape 1 even at a fast transfer speed of the tape, enabling a high speed movement.  Then, transfer is made possible so as to satisfy the signal without being influenced by the extent of a track deviation.
