La composition de l'alliage resultant consiste en au moins 5 pour cent en poids de chrome, de 0 a 3 pour cent en poids de carbone, un composant x, un composant z, et en une balance d'un ou plusieurs composants de nickel, cobalt et fer avec des elements et des impuretes eventuels, ou le composant x est forme par une ou plusieurs des compositions suivantes: i) au moins 2 pour cent en poids au total d'un ou plusieurs des elements suivants: aluminium, titane, tantale et niobium; ii) au moins 5 pour cent en poids au total d'un ou des deux elements suivants: tungstene, molybdene, et iii) au moins 60 pour cent en poids de nickel, le composant z comprend mp pour cent en poids d'un ou plusieurs metaux du groupe platine melanges a mc pour cent en poids d'un ou plusieurs metaux complementaires du platine avec 0,1 <= mp + mc <= 5 et 0,3 <= mp/mc <= 20. La quantite mp du metal du groupe platine se situe, de preference, entre 50% et 95% en poids du total (mp + mc), et plus particulierement les quantites de metal du groupe platine et de metal complementaire du platine sont choisies en proportions stochiometriques par rapport aux composes intermetalliques pouvant se former entre eux. Les alliages ameliores sont d'un usage particulierement approprie aux composants d'une turbine a gaz.

Abstract: Ce procédé consiste d'abord dans l'élaboration d'une structure classique qui comporte un substrat silicium de type P (12) muni d'une région de sous-collecteur enterrée (14) et recouvert par une couche épitaxiale de type N (10). Des régions d'isolation (18) en SiO2 définissent les régions base et collecteur et la région de traversée de collecteur (16). La région base comprend la région extrinsèque (34, 36), formée par diffusion à partir de la couche de silicium polycristallin dopée de premier niveau (24) et la région intrinsèque ou active (38). La région d'émetteur (42) est formée de façon classique. Le contact avec la région d'émetteur est réalisée, soit grâce à la combinaison d'un contact en silicium polycristallin dopé de deuxième niveau (43) et d'un contact métallique (E 48) c'est le cas de la figure 11, soit directement avec un contact métallique (E 58), cette dernière réalisation est montrée sur la figure 14. Le procédé permet la réduction de la résistance de base du transistor et de la capacité collecteur-base. L'invention trouve donc application dans les circuits ulta-rapides à forte densité d'intégration.

Abstract: On the two main surfaces of a semiconductor disc of a large diameter, high-performance semiconductor component, there are soldered one bundle each of metal wires. The other ends of the metal wires are soldered to heat dissipating discs. The metal wires, with increasing distance from the center, are of increasing lengths in order to absorb the differences in the thermal expansion of the semiconductor disc and the heat dissipating discs. Metal ring portions and a ceramic housing complete the semiconductorcomponent. A secure and desirable contact of the semiconductor discs is achieved without the application of pressure.

Abstract: Externally coated steel tube is made from steel strip by longitudinally folding and welding the strip to form the tube (200), preheating (205) the tube and applying powder (206) to the exterior of the preheated tube. The tube is then baked at a higher temperature before cooling. In order to achieve an even and continuous coating when using thermosetting material as the coating powder, the temperature given to the tube by the preheating (205) is such as to cause the coating powder to melt and spread out immediately on application to form a substantially continuous coating, before substantial curing of the coating material occurs. Suitably, this is provided by passage of the tube through a box (207) which maintains the temperature of the tube.

Abstract: Calcined gypsum (stucco) is treated by blending therewith small portions of water (about 1-10% by eight of the stucco), allowing it to heal, and grinding the healed stucco to increase its surface area. This results in a reduction in water demand with good retention of set strength. If the treated calcined gypsum is not used shortly after the healing procedure, it should be dried before grinding to provide storage stability. The reduced water demand is particularly useful in gypsum board manufacture.

Abstract: A fully digitised receiver comprising oscillator (2), mixer (1), IF filter (3) and demodulator (demod) is described which operates by the quadrature method. The oscillator frequency is selected to be equal to the received frequency. All units have their own, partially multiple processors and memory units. The low-pass units of the IF filter (3) consist of the cascading of a transversal (transv. TP) and a recursive (rek. TP) filter. After the transversal filter, the sampling rate is reduced. The transversal and/or the recursive filter can also consist of several stages with the sampling rate decreasing in each case. The transversal filter advantageously exhibits a large form factor whilst the recursive filter determines the final form factor of the IF filter (2). The digital receiver corresponds to the requirements for economy of multiplication and freedom from loops in the time-critical processor sections. It is suitable for input bandwidths of up to 50 MHz as soon as a speed-power product of 30 fJ becomes feasible. <IMAGE>

Abstract: In a push button switch including a housing (1), a depressible plunger (7) which is spring-urged towards a first, rest, position in the housing, and a pair of cooperating blade springs (3) each of which is fixed relative to the housing at one end and at the other, free, end carries a respective electrical contact (10) each spring (3) having a shoulder (14) which is engageable by a respective portion of the plunger (7) during depression of the plunger to cause the springs (3) to move inwardly towards each other such that the respective electrical contacts (10) engage, the arrangement being such that the depression force required on the plunger to cause its said portions to ride over the shoulders (14) is greater than the depression force required to complete the depression once the said portions have ridden over the shoulders, the plunger (7) includes an integral spacing member (12) which is located between the blade springs such that the two springs, and hence their respective electrical contacts, are spaced apart by the spacing member (12) when the plunger is in said first position. The spacing member (12) serves to prevent accidental coming together of the electrical contacts (10) in the event of a mechanical shock to the switch.
