Abstract: Un amplificateur à commande de gain adaptable (12) est décrit en relation avec un système audio, afin de permettre le réglage du volume de sortie d'un haut parleur (16) automatiquement en réponse à un signal d'interférence (21) tel qu'un bruit de fond. Ledit amplificateur comporte un circuit diviseur (30) qui calcule le rapport d'une moyenne de temps d'un signal altéré (20, 21) qui résulte de la combinaison entre un signal de sortie régulé (20) et le signal d'interface (21), afin de produire une tension de commande qui commande le gain de l'amplificateur. Afin de réduire la gamme dynamique du quotient dudit rapport, on incorpore dans le circuit diviseur (30) un circuit à rapport logarithmique. Les circuits de l'amplificateur comprennent ''un canal détecteur'' et ''un canal de référence'', afin de permettre l'extraction desdites moyennes respectivement du signal altéré et du signal de sortie régulé. Un procédé est également revendiqué.

Abstract: DNA sequence which codes DNA polymerase of animal cell origin having DNA synthetase activity but no nuclease activity is cloned, and the DNA polymerase can be produced in a high yield by incorporating the cloned sequence in a plasmid together with a suitable vector and introducing the recombinant plasmid into host cells such as Escherichia coli to express the code. Since the DNA polymerase can be produced in a high yield, DNA polymerase of animal cell origin can be purified with good efficiency.

Abstract: Ein Regelkreis (1,18,19,21,9,8,7,6,5,4,3,2) umfasst den Ultraschallschwinger (1) und den spannungsgesteuerten Oszillator (7). Er hält die Wirkleistungsaufnahme auf einem Sollwert (19), der in einem Komparator (21) mit der momentanen Wirkleistungsaufnahme verglichen wird. Ein Ausgang eines Rechteckoszillators (12) ist mit dem Steuereingang des spannungsgesteuerten Oszillators (7) verbunden. Dieser Rechteckoszillator (12) wird in Betrieb gesetzt, wenn im Regelkreis keine Regelschwingungen oder nur solche auftreten, die kleiner sind als ein vorbestimmter Schwellenwert (14). Der Ausgang des Rechteckoszillators (12) ist über eine Diode (10) mit dem Steuereingang des spannungsgesteuerten Oszillators und über eine andere Diode (11) mit dem Steuereingang des Komparators (21) verbunden. Der Regelkreis stellt die Wirkleistung mittels der Anregungsfrequenz zwischen der Serienresonanz und der Parallelresonanz ein. Am Oszillator (7) wird das Zusatzsignal zusätzlich zum Regelungssignal des Regelkreises angelegt. Die Periode des Zusatzsignals ist länger als die Änderungszeitkonstante am Steuereingang des Oszillators (7) und der Hub des Zusatzsignals ist so bemessen, dass die Frequenz des Oszillators (7) einen vorbestimmten Frequenzbereich durchläuft. Der vom Regelkreis allein erzeugbare Frequenzhub kann kleiner sein als der Frequenzabstand zwischen der Serienresonanz und der Parallelresonanz. Die Spannung am Ultraschallschwinger (1) kann von konstanter Amplitude sein. Eine Verwendung ist die Zerstäubung einer Flüssigkeit durch einen mit einem Zerstäuberteller versehenen Ultraschallschwinger.

Abstract: Speech is analysed to derive the parameters of a synthesis filter and the parameters of a suitable excitation, selected from a codebook of excitation frames. The selection of the codebook entry is facilitated by determining a single-pulse excitation (eg.using conventional "multipulse" excitation techniques) and using the position of this pulse to narrow the codebook search. The codebook entries can be subject to the limitation that some entries are rotationally shifted versions of other entries.

Abstract: A disposable protective gown and process for making the gown. The gown is composed of a body portion (12) which extends over the shoulders of the wearer and which has a pair of sleeves (14) which extend outwardly from opposite sides. Each sleeve (14) is attached to the body portion over an angle of attachment greater than 180° and less than 300°. A thumb loop (48) is formed at the end of each of the sleeves and is shaped to engage the saddle of the thumb of a wearer. In forming the gown, after the body portion has been cut and the sleeves formed, the sleeves are attached to the body portion by heat sealing (42) half the sleeve, then rotating the sleeve so that a second portion of the sleeve is attached to the gown, with the total angle of attachment not exceeding 300°. In order to prevent inadvertent sealing of both sides of a sleeve together, each sleeve includes a circumferential notch (40) which extends for a length up to that comprising the portion of a the sleeve that is not attached to the body of the gown.

L'ensemble pointe d'angle (10) décrit comporte une partie angulaire (18) solidarisée avec l'outil, des premier et second rembourrages de transfert de charge étant définis sur un bord antérieur de ladite partie, et des premier et second trous étant définis à l'intérieur de celle-ci, ainsi qu'une pointe d'angle (20) conçue pour être fixée de façon libérable à la partie angulaire (18). Une partie terminale postérieure de la pointe d'angle présente une portion (56) de transfert de charge comprenant des première et seconde surfaces de transfert de charge (58, 60) destinées, au montage, à coïncider avec les premier et second rembourrages de transfert de charge (28, 30) de la partie angulaire, ainsi qu'une seule portion latérale droite (46) pourvue de premier et second trous destinés, au montage, à coïncider avec des premier et second trous respectifs (24, 26) de la partie angulaire sur un outil (12). En faisant coïncider les première et seconde surfaces de transfert de charge avec les premier et second rembourrages de transfert de charge de la partie angulaire tandis que la pointe d'angle est assujettie à la partie angulaire par un moyen de précontrainte (70), on obtient une fixation serrée entre la pointe d'angle (20) et la partie angulaire (18).

Abstract: A current of predetermined frequency is fed to a coil (24) wound around a ferromagnetic core (23) through a fixed impedance means (22). A magnetic flux measure­ment is performed in terms of a level of a DC component of a voltage (e₀) generated across the coil (24). A DC bias is added to the current of predetermined frequency, and the resultant current is applied through the fixed impedance means (135) to the coil (137) wound around the ferromagnetic core (136). A magnetic flux measurement is performed in terms of a level of a DC component of the voltage across the coil (137). A magnetic flux measuring method and apparatus for embodying the same have a high sensitivity in detecting a minute magnetic flux and an improved temperature characteristic because an output voltage little varies against a temperature variation. A magnetic flux measuring method and appara­tus for embodying the same, when they are applied to a leakage flux flaw detection using a saturable magnetic flux sensor, is capable of expanding a measuring span of the magnetic flux sensor, thereby to improve a flaw detection performance.
