Patent EP-0127382-A1 (EP)
Inventor: PAIK WOO H
IPC: G11B20/10
Filed: 1984-05-16
Abstract: In the scrambling system, an analog audio signal is converted into a digital signal to provide a sequence of digital signal samples. Each digital signal sample is compressed to provide compressed signal samples having a sign bit, three exponent bits and seven mantissa bits. Each bit of each compressed signal sample is exclusive-OR'd with a unique keystream to thereby scramble the autio signal. A Hamming code generator generates code bits for correcting singular errors in a combination of the sign bit, the exponent bits and the code bits; and a parity bit generator generates a parity bit for detecting double errors in a combination of the sign bit, the exponent bits and the code bits and for further detecting an error in the most significant mantissa bit and/ or the parity bit. The bits from a plurality of successive compressed, error-encoded signal samples are interleaved and serialized in orderto separate the bits from any single sample by at least a predetermined duration associated with an FM discriminator click. The serialized signal samples are combined to provide two-bit digital words. The digital words are converted to digital PAM data signals. The digital PAM data signals are converted to an analog signal to provide the pulse-amplitude-modulated signal. The descrambler system descrambles the scrambled audio signal. Singular errors in a scrambled signal sample are detected and corrected by a Hamming error corrector. Double errors are detected by a parity bit check and compensated for by repeating the last received error free signal sample.

Abstract: slicing machine for slicing food products, particularly meat and other meat products 7 comprises a rotating blade 1 which either has a spiral cutting edge or a circular cutting edge and is mounted for planetary motion, and means 8,9,11,12 to feed the product towards the blade 1 so that upon each rotation or gyration of the blade a slice is cut from the face of the product 7. The slicing machine also includes first means 34, 35 for monitoring the position of the blade 1 and outputting a signal when the blade is in a predetermined position, second means 19 for establishing when the blade 1 is cutting the slice to form the last slice in a group of slices and outputting a signal indicating this condition, a manually operated interrupt switch 27, and interrupt means 18 to interrupt the feed of the product to be sliced towards the blade 1 of the slicer. The interrupt means 18 is enabled by the operation of the first 34, 35 and second 19 means and the interrupt switch 27 simultaneously so that, after manual actuation of the interrupt switch 27, feed of material is disabled only at a time when a complete shingled group of slices has been formed.

Abstract: A gating technique is disclosed for split gate bidirectional power FET structure (2), including AC application. First and second channels (14, 16) are initially gated ON to provide fast field effect turn-on. One of the channels such as (14) is then gated OFF such that current is instead injected across the junction (18) between the drift region (4) and the respective channel-containing region (6) to afford bipolar conduction, which is desirable because of its lower ON state resistance. The noted channel such as (14) is then gated back ON to again afford field effect conduction between source regions (10, 12) and enable fast turn-off.

Abstract: Afin de donner à des calibres de travail une longueur extrêmement précise, la pratique habituelle consiste à soumettre un élément de calibre de travail à un traitement de finissage très précis, et à comparer les dimensions obtenues avec des gabarits standard, qui sont très coûteux, ou à contrôler les dimensions à l'aide d'instruments de mesure de haute précision, encore plus coûteux. L'invention concerne un système comprenant des gabarits standard (2) et des éléments spéciaux (44) de calibre de travail, de même qu'un dispositif spécialisé associé de mesure (Fig. 3). Ce système permet de produire un calibre de travail (44) par simple ajustement de la longueur de deux éléments mobiles fixes l'un par rapport à l'autre (4, 8). L'ajustement est réalisé dans l'instrument de mesure par comparaison avec les dimensions d'un gabarit standard mesuré au préalable par le dispositif de mesure. Les gabarits (2) et les calibres de travail (44) peuvent avoir une forme similaire, par exemple celle d'un corps cylindrique (4) sur lequel fait saillie une goupille (8) de définition de mesure, ce qui permet d'obtenir une conception économique des gabarits et un ajustement aisé des calibres de travail.
