Abstract: A flyback converter including a first (6) and a second (8) switching transistor, a first (10) and a second (12) rectifier diode, and a primary winding (14) of a transformer, which parts are connected in a bridge arrangement. The first switching transistor (6) receives its drive by positive feedback via a secondary winding (30), a coupling capacitor (36) and a series resistor (38, 40). Upon commutation of the voltage on the secondary winding (30) the first switching transistor (6) is turned off, a discharge diode (44) providing a discharge path for the coupling capacitor (36) in order to achieve that the first switching transistor (6) is turned on more rapidly in the next switching cycle. However, the discharge diode (44) limits the cut-off voltage on the control electrode of the first switching transistor (6), so that turning off proceeds comparatively slowly. This effect is eliminated by a voltage source (46, 48, 52) and a further switching transistor (54) which is turned on upon commutation. The further switching transistor (54) then produces a higher cut-off voltage on the control electrode of the first switching transistor (6), as a result of which the first switching transistor (6) is turned off more rapidly.

Abstract: A bump structure for bonding leads to a semi-conductor, in which the bump has a thin lower portion (32) which overlaps and seals the edges of the passivation layer (18), and a thicker upper or stem portion (38) of smaller lateral dimensions to fit within the margins of the opening in the passivation layer. Thus, during bonding, downward compressive forces are applied primarily through the bump stem directly to the metal termination pad (14) beneath the bump, and very little force is applied to the edges of the passivation layer. This reduces the likelihood of passivation layer cracking, increasing device reliability. Because the bump stem is formed within the margins of the passivation layer opening, it has a flat top, resulting in better lead bonding. <IMAGE>

Abstract: Improvements to the manufacture of yarn spun on closed-end, high draft spinning systems, in which a yarn structure is formed in which each of the constituent fibres migrates between the surface and the core of the yarn so that part or parts of each fibre are trapped and bound by parts of other fibres in the yarn cross-section. The constituent fibres can migrate cyclically between the core and the surface of the yarn or the migration or withdrawal of individual fibres can be impeded by a degree of inter-fibre entanglement deliberately introduced in the yarn structure. Mechanisms for producing the yarn structure are also described.

Abstract: The present invention relates to a computer tomography system which measures the thickness and edge position of hot-rolled steel. X-rays produced by two X-ray sources are directed, through the sample being measured, to a plurality of radiation detectors. The radiation detectors measure the attenuation of the X-rays caused by the sample. The attenuation levels sensed by each detector are correlated with each detector's physical location. This information is collected as each X-ray source illuminates the radiation detectors. The collected information is triangulated or averaged, as necessary, to determine the dimensions and position of the measured sample.

Abstract: A disk player that will play only athorized disks. Predetermined data blocks, including those in the lead-in section of the disk which contain content-related data, are processed to derive an authorization code. The authorization code is stored on the disk in encrypted form, using the private key of a public-key cryptosystem pair. The player processes the same disk data to derive a computed code; the player also uses the paired public key to decrypt the encrypted authorization code on the disk. Play of the disk ensues only if the decrypted authorization code matches the computed code. The same technique can be used to control not play of the disk as a whole, but play in certain specific modes. <IMAGE>

Abstract: A thermal spraying method involves the creation of a coating comprising titanium wire in the presence of nitrogen. The apparatus of the invention comprises a nozzle which has a cylindrical throat, with feedstock guides which guide the feedstock wires to a point of intersection in the throat. A current is passed through the wires to cause an arc in the throat, and a nitrogen rich gas under pressure is forced through the throat, generating a spray of molten particles which is used to coat a substrate. In a variation of the method, one of the feedstock wires comprises a binder metal, which produces a coating having enhanced toughness.
