Abstract: Un circuit de commande de limitation d'intensite (10) recoit un premier signal d'entree de niveau logique (01) et commande une broche de sortie (26). Un noeud (14) est tire a la terre par un transistor d'abaissement (16) qui recoit le premier signal d'entree (01) et est entraine vers un etat de haute tension par un transistor de montee (12). Un transistor de commande (28) est excite par un etat de haute tension au niveau du noeud (14) et est coupe par un etat basse tension au niveau du noeud (14). Le transistor de commande (28) est connecte pour fournir un etat haute tension sur la broche de sortie (26). Un transistor d'abaissement (30) est connecte pour recevoir le premier signal d'entree (01) de maniere a ramener la broche de sortie (26) a la terre. Une serie de transistors (18, 20, 22) sont connectes entre les bornes de porte et de source du transistor de commande (28) de sorte que lorsque la tension de porte-a-source du transistor de commande (28) depasse les seuils combines des trois transistors (18, 20, 22) ceux-ci seront excites et limiteront par consequent la tension maximum porte-a-source du transistor de commande (28). Ceci, a son tour, sert a limiter l'intensite maximum du courant passant par le transistor de commande (28). Des transistors d'invalidation (17, 32) sont prevus pour produire une sortie d'impedance elevee sur la broche de sortie (26).

Abstract: An inductive heating device for uniformly heating a workpiece at rest has in one embodiment of the invention a plurality of heating coil units (31 to 36) disposed so as to surround the workpiece (21). The heating coil units (31 to 36) are connected in parallel to a power source, and a transformer may be used to vary the voltage across the terminals of the outermost units to increase the current flowing through these outermost units. The device, therefore, has a very short insufficient heating temperature zones attributable to end magnetic flux effects. 
     In another embodiment using a non-divided coil, the end effect may be reduced by adjusting the relationship between the distance between the end of the coil and the end of the workpiece and the clearance between the coil and the workpiece.

Abstract: To enhance the intelligibility of speech, the consonant sounds are intensified and, in effect, their intensity equalised to that of the vowel sounds in a speech waveform. A short-time estimate of the relative spectral shape of an input speech signal is determined by envelope detectors (24) operating on the outputs of band pass filters (20). Control means are provided to respond to such relative spectral shape estimate by dynamically controlling a modification of the spectral shape of the actual speech signal so as to produce a modified output speech signal, the control means comprising a combination matrix (28) operating on the outputs of the envelope detectors (24) with a matrix of coefficients and producing weighted signals (29) as control signals. The control signals (29) act on gain selecting logic (30) to determine the gains of multipliers (31) through which respective different portions of the frequency spectrum of the input speech are coupled to a summation circuit (32) producing the consonant - enhanced output speech signal, the respective different portions of the frequency spectrum of the input speech being produced by a bank of filters (20) supplying the envelope detectors (24) or by a set of different filters (26).
