摘要： Picture display device having a display tube (3) and a deflection unit (9) comprising a field deflection coil and a line deflection coil (11). To comply with a predetermined interference radiation standard, the picture display device comprises a first set of (horizontal) interference suppression coils 18, 19 arranged symmetrically relative to the plane of symmetry of the line deflection coil and a second set of (vertical) interference suppression coils 18a, 19a arranged at right angles to the plane of symmetry of the line deflection coil, which coils are oriented in such manner and in operation are energizable in such manner that, measured at a predetermined distance from the picture display device, at least the strength of the local magnetic dipole field is below a desired standard. Each coil of the second set preferably comprises at least two sub-coils arranged parallel to each other at a given distance in order to reduce the energy content of the coil system.

摘要： A method of manufacturing a plate-shaped permanent magnet (7) which is to be arranged in an air gap of a core (1) for a transformer or choke coil and which consists of a number of permanent magnetic portions (29) which are made of a metal alloy having a high magnetic remanence and which are magnetized perpendicularly to the plane of the plate. A plate (11) of the alloy is fixed between two insulating foils (13, 15) after which this assembly is arranged on a flat backing (17) and is rolled in two mutually perpendicular directions (25, 27) by means of a cylinder (19) whose outer surface is provided with grooves (23). The plate (11) is thus very simply fractured to form a very large number of portions (29).
