Title: Circuit de commande en technologie mos.
Inventor: JANG HYEON-SUN
IPC: H03K17/687
Filed: 1990-10-31
Abstract: Un circuit de commande en technologie MOS, composé d'un étage de sortie symétrique (transistors NMOS M4 et M5) et d'un circuit survolteur (BT) qui fournit sur le nœud (N1) à l'entrée de la grille du transistor (M4), le survoltage (Vcc + alpha) nécessaire à commander l'état "haut" sur la borne de sortie (OT), caractérisé en ce que ce circuit de commande comprend un circuit limiteur (CP), qui limite le niveau (Vcc + alpha) sur le nœud (N1) à une tension de référence (VR) indépendante de la tension d'alimentation (Vcc), et cela en laissant écouler l'excès de charges du condensateur de suralimentation (Cb) depuis le nœud (N1) vers la borne de sortie (OT). Cette limitation à une tension de référence constante (VR) empêche les variations de tension (Vcc) et le bruit sur sa ligne d'alimentation, de se répercuter sur le niveau de sortie (en OT). Le fait de décharger le condensateur (Cb) vers la borne de sortie (OT) permet à cette sortie (OT) de commander une charge capacitive plus élevée.

Title: Anti-radiating monopode resonator
Inventor: JEAN-PASCAL VALENTIN
IPC: H03H9/08
Filed: 1991-12-20
Abstract: The invention relates to a resonator consisting of a piezoelectric crystal linked to the base of a housing by means of a single fixing occupying a narrow region of the periphery of the crystal, and kept at a constant temperature by virtue of a heating element arranged close to the fixing. The mechanical stresses applied to the housing are not transmitted to the piezoelectric crystal due to the principle of the fixing. Moreover, specific insulation of the crystal forces the thermal exchanges to take place solely through the fixing for holding the crystal, to the exclusion of any other path. This single passage for the thermal flux is regulated in terms of temperature by a temperature sensor placed in thermal contact with the fixing for holding the crystal. The crystal (10) covered with a metallic layer (11) is linked to the base (31) of the housing (30) by a narrow foot (20) equipped with a heating means (22) and with a temperature sensor (21). The housing is evacuated and the electrical supplies are effected by means of sealed passages (32 to 37). The device according to the invention is particularly intended for producing stable frequency references, of low consumption and insensitive to the effects of the environment (on-board avionic and spatial references).

Title: Self=supporting vaulted and collapsible panel - made from thin layer of plastic, e.g. with metallised surface, tensioned by thin elastic metal slats, e.g. of beryllium-copper alloy
Inventor: JOZEF RITS WILLY
IPC: B64G1/22
Filed: 1992-03-24
Abstract: The self-supporting vaulted and collapsible panel, for use e.g. in space as a reflector, comprises a thin supple membrane (2) and a series of ribs (3) to tension it. The ribs are made from thin slats with two main surfaces, one of which faces towards the membrane, and the membrane has guides for the slats. At least one end of each guide has a pocket to receive a slat so that in its deployed state the ends of the slats exert an axial force on the membrane and tension it, while in the collapsed state the membrane occupies only a small volume for stowing inside an orbital launcher. The slats are designed to follow the curvature of the deployed membrane and themselves have a curved cross-section; they can be made from a very elastic metal alloy, e.g. of beryllium and copper. The membrane is made from a plastic such as Kapton (RTM), reinforced with fibres, preferably of Kevlar (RTM), and it can be metallised to reflect electromagnetic waves, especially infra-red, visible light, U-V light and/or microwaves. ADVANTAGE - Large dimensions with great stability and precision.

The correct code activates a laser reflector (22) , by operating a motor (28) to open shutters (24) in front of the reflector. A ground based laser transmitter (20) is synchronised to the interrogation signal, transmitted (21) , reflected off the reflector and received by the detector (23) identifying aircraft position. ADVANTAGE- Directional response gives secure positional response to send transmitter only.
