IPC: G03G15/16
Filed: 1989-11-24
Abstract: PURPOSE:To prevent faulty transfer from occurring without using a transfer bias power source by providing an optical semiconductor on the surface of a transfer guide plate which guides a transfer paper introduced between a photosensitive body and a transfer charger and making the transfer guide plate face a position where it is electrostatically charged by the transfer charger. CONSTITUTION:The transfer guide plate 2 is at the position where it is electrostatically charged by the transfer charger 4, and the optical semiconductor 7 provided on the surface of the guide plate 2 is electrostatically charged by the corona discharge of the transfer charger 4. As a result, since the transfer paper 3 is supplied in contact with the transfer guide plate 2 by the electrostatic attracting force of the optical semiconductor 7, it is made in contact with the photosensitive body 1 excellently. Then, the dirt such as paper powder, etc., caused by the transfer paper 3 is eliminated by the electrostatic attracting force of the optical semiconductor 7. However, the electrostatic attracting force of the optical semiconductor 7 on the surface of the transfer guide plate 2 is eliminated, for example, when the optical semiconductor 7 is exposed to light at the time of cleaning, so that the dirt is easily removed from the guide plate 2. Thus, the faulty transfer such as the missing of an image, etc., is prevented from occurring without using a transfer bias power source.

Abstract: PURPOSE:To sufficiently protect a charging circuit by providing a charging current forced cutoff circuit, and forcefully cutting off the charging circuit preferentially to power feed control if charging is not stopped when a fixed time elapses after high-voltage capacitors are started charging. CONSTITUTION:A timer circuit 16 is operated when a power switch 3 and a charging switch 4 are turned on, and a charge stop signal S2 is fed to a charging switch control circuit 14 when the period required to normally operate an X-ray tube 9 or slightly longer or the period until the permissible maximum charging voltage is attained elapses.

Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To change the seal performance of only the required portion and make the width of a seal section as narrow as possible by continuously forming the seal section by printing such as screen printing on the seal portion of the coupling face of a member, and forming a recess or a stripe groove in the middle in the width direction of the seal section. SOLUTION: A seal section 21 is constituted of a one-ridge section 22 with a ridge-like cross sectional shape along a seal portion, a two-ridge section 23 with a ridge-like cross sectional shape formed with a stripe groove 25 at the center section in the width direction and having two apexes continuously connected along the seal portion and nearly equal in height and a bottom section in common, and a merge section 24 with a ridge-like cross sectional shape formed with a recess 26 at the center section and having two apexes continuously connected and nearly equal in height and a bottom section in common. When the stripe groove 25 and the recess 26 are formed, the contact area of a coupling face is reduced, face pressure is increased, and a compressive deformation easily occurs.  For this reason, the two-ridge section 23 is formed at a portion where the face pressure becomes higher than the required pressure or a portion requiring high seal performance.
