Patent EP-0264046-A1 (EP)
Inventor: HOFMANN RUEDIGER
IPC: H03K3/356
Filed: 1987-10-05
Abstract: In the switching matrix, column lines (s), in each case with two signal conductors connected to differential outputs of differential line drivers (E), lead via switching element pairs (Kij) to row lines (z), each one similarly having two signal conductors to which the two signal inputs of a differential amplifier (A) with a switching response are connected. The switching elements (Kij), in each case formed with a switch transistor, its control electrode (s) being supplied with a through- connecting or blocking signal, while its main electrode is connected to the matrix output line, each have a preceding transistor (Tne), which forms a series connection with the switch transistor and which is connected by its control electrode to the matrix input line (sj), while its main electrode which faces away from the series connection is connected via a sampling transistor (Tna) to USS (earth); the relevant matrix output conductor (zi) is connected via a pre-loading transistor (tpi) to UDD. The pre-loading and sampling transistors are controlled in opposite directions to one another by means of a switching matrix select clock which divides a bit through-connection time span into a pre-loading phase and the actual through-connection phase.

Abstract: Device for displaying television pictures by means of a deflection unit placed on the neck of a colour picture tube and comprising a system of line deflection coils and a system of field deflection coils. The neck accommodates an electron gun system for producing three coplanar electron beams: a central beam and two outer beams. The system of field deflection coils is provided on the gun side with two (bent) plate-shaped elements of a soft-magnetic material located at a distance from each other in the circumferential direction of the neck of the tube which elements each have a neutral position, in which neutral positions the distance between the centres of each element and the outer beams is equally large and in which the distance between the centres of the two elements and the one outer beam can be rendered larger than the distance to the other outer beam for correcting picture balance errors.

Abstract: The invention relates to a CCD having a so-called diode cut-off input, a reference voltage being applied to the input diode and the input signal being supplied to an input gate located in front of the first clock electrode. Especially if the electrodes are composed of a transfer part and a storage part with an incorporated potential dif­ference, it is possible that incomplete charge transport occurs from the input to the first clock electrode. In or­der to avoid this incomplete charge transport and/or to be able to enlarge the dynamic range of the input signal, a larger clock voltage, for example 10 V, is applied to the first clock electrode than to the following clock elec­trodes, for example 5 V. In a preferred embodiment, the 5 V clock voltage can be supplied for this purpose  via  a boots­trap circuit ot the first clock electrode.

Abstract: Procédé de production de tissus non tissés consistant à collecter les fibres véhiculées par un fluide à haute vitesse sous la forme d'une bande, et à les introduire dans un dispositif d'emballage de tissus pour qu'elles se superposent. Dans ce procédé, la bande présente de préférence une distribution en section transversale telle que le poids par unité de surface dans les deux bords va en diminuant graduellement en direction du bord. Ce procédé permet de produire une bande filamenteuse ou un tissu non tissé filamenteux de grande largeur et présentant une quantité remarquablement faible d'irrégularités, à l'aide d'une installation de production de tissus non tissés dans laquelle des machines à filer mono- ou bibroches sont reliées directement entre elles. Il est ainsi possible de produire de manière économique un tissu non tissé large en petites quantités par le procédé de filage en connexion. En outre, la largeur ou le poids par unité de surface du produit peut être modifié sans modifier les conditions de filage, de sorte que ce procédé est également indiqué pour produire une variété de produits avec moins de perte lors du changement du type de production.

Abstract: A curved cylindrical segment platen (18) has a concave touching surface (18b). An interrogating slit light beam is scanned around the platen to scan a finger held against the touching surface. An optical imaging system images (20) the zone illuminated onto an array of photo-transducers (22) to provide a signal representing the fingerprint. The optical system is rotated (40) around the platen. The axis (17) of the interrogating light beam (16) is substantially normal to the touching surface (18b). The axis (28a) of the imaging system is off normal by about 56 degrees, an amount which is greater than a critical angle equal to the maximum angle of refraction (MAR) in the platen. This critical angle is approximately 41 degrees. The axis (28) of the imaging system is also off normal to the non-touching surface (18a) by an angle that is less than this critical angle of 4l degrees and thus less than the angle of total internal reflection (TIR). As a consequence, the image at the photo-transducers provides a completely dark valley zone and a sharply contrasting light image ridge ,zone.

Date Jan. 12, 1989.In a manually operable discharging apparatus, the discharge nozzle has an at least two-stage atomizer, in which the medium flow, following pre-atomization, is atomized by surge-like acceleration with a whirled, fine compressed air flow, e.g. according to the Laval, effect, so that even finer droplets are obtained. For this purpose to the discharge nozzle, a separate compressed air channel portion upstream of the end opening supplies compressed air from a time immediately before the supply of medium to a time after its supply. The compressed air can be produced in simple manner by a compressed air pump combined constructionally with the medium pump and operable together therewith by means of a single handle and which in the extension of medium pump is provided immediately adjacent to its outer end and whose pump cylinder is formed by the cap-like handle. The compressed air flow can also be passed to other points of the discharging apparatus, e.g. for cleaning the medium outlet channel for discharge nozzle and can be used for control functions for valves, particularly outlet valves.
