Patent EP-0455893-A1 (EP)
Inventor: WILLOCX EDDIE LOUIS MARIE
IPC: H04M19/00
Filed: 1990-05-11
Abstract: Each line wire is separately biassed by DC potentials feeding inputs of the respective line wire driver amplifiers, the first potential (BA) being nearer ground and the second at an equal distance from the negative supply used to power the amplifiers so as to allow a suitable AC swing for the speech and metering signals also feeding the inputs of the amplifiers. The second potential (BB) is obtained from a DC synthesizing loop voltage and to which is added (OA6) the first potential, both potentials being also combined (OA5) to control a switched mode DC/DC converter delivering the negative power supply. In addition to both potentials being filtered with reference to ground, another measure reducing noise relies on AC signals push-pull outputs driving the amplifier inputs, also in push-pull, through four resistances.

Abstract: Solutions of hydrogen peroxide in sulphuric acid are used to treat aluminium metal, to form an artificially applied oxide layer having a profiled surface with protrusions which is very suitable for adhesive bonding or the application of organic coatings. A copper salt may be used as an accelerator, alone or with an amine. Treatment may be effected at temperatures up to 90 o C. An inorganic coating may be applied to overlie and protect the profiled oxide layer. An advantage is the possibility of using aluminium metal without a prior cleaning step.

Abstract: An image forming apparatus having a photosensitive drum and a transfer drum including a transfer member carrying sheet substantially contacting the photosensitive drum. In order to enable a toner image formed on the photosensitive drum to be efficiently transferred to a transfer member, the apparatus has a pressing sheet for outwardly pressing the transfer member carrying sheet from the interior of the transfer drum and a conductive member provided on the side of the pressing sheet adjacent the transfer member carrying sheet. The conductive member serves to realize a uniform distribution of surface potential on the pressing sheet and to maintain the surface potential constant, so that the intensity of the electric field applied to the corona discharge is made constant at a low level so that a stable transfer corona is applied to the transfer member carrying sheet, thus ensuring good quality of the transferred image.
