Abstract: Nouveau procédé pour former un cristal du groupe quaternaire III-V sur le cristal du groupe III-V en conservant la superposition du réseau par rapport à celui du cristal du groupe III-V. Il est facile de former un super-réseau composé d'une première couche de cristaux du groupe binaire III-V (désigné III1-V1) et d'une couche de cristaux du groupe ternaire III-V (III1-III2-V2) sur un substrat d'un cristal du groupe III-V, les réseaux des deux couches étant maintenus par rapport au substrat. On obtient une couche de super-réseau plus stable si le rapport de l'épaisseur de pellicule du cristal III1-V1 par rapport à celle du cristal III1-III2-V2 est choisi pour que les compositions ainsi constituées gardent la superposition du réseau par rapport au cristal d'origine lorsque le super-réseau forme spontanément un cristal mélangé ou dopé d'impuretés.

Title: Radiant heating element
IPC: F24C15/10
Filed: 1987-05-28
Granted: 1991-11-13
Abstract: In a radiant heater unit (1) for heating through a hotplate (2), the periphery of the heating field is formed by an initial cooking marginal heating system (9), which is e.g. operated by a short-circuit connection (19), so that it passes much more rapidly from the cold state into the visible glowing state and also in the marginal region use is made of the faster heat transfer there to the bottom (3) of the cooking utensil. The increased radiant power density can also be obtained by other measures, namely by modified insulating conditions in the vicinity of the marginal heating system, by using a PTC resistor in the vicinity of the inner partial power system and similar measures.

Date Nov. 6, 1986.Si-N groups in silazanes (which may be siloxazanes) are cleaved in the presence of a suitable catalyst or one or more reactants containing an Si-H group and an N-H group (in the same molecule or in different molecules) are reacted in the presence of a suitable catalyst. New silazane products result including oligomers and polymers. Suitable catalysts include metal carbonyl complexes and heterogeneous metal catalysts such as platinum on carbon. Immediate products of reaction such as products containing Si-H and N-H groups resulting from Si-N cleavage and Si-N products resulting from Si-H+N-H reactions undergo further reaction, resulting in many cases in a mixture of oligomers or of oligomers and polymers. The initial reactants may be open chain or ring compounds containing Si-N or Si-H+N-H in an open chain or in a ring or as pendant groups.

Abstract: An optimal parametric signal processor, which receives autocorrelation coefficients, provides lattice coefficients in an optimal manner, and allows the use of any number of available parallel processing units. The signal processor may be implemented in a fully parallel or fully sequential manner, or in a "parallel-partitioned" implementation which provides the benefits of parallel processing, manageable hardware complexity, and optimal signal processing for a given number of available processors. By using a "lattice basic cell" structure, hardware complexity is minimized.

Abstract: A process and device for producing pipes or similar elongated profiles by powder metallurgy. A thin-walled sheath is filled with a metal and/or metal-alloy powder, if necessary after the powder has been pre-compressed by vibration or a similar process. The thin-walled sheath is then closed and cold- and/or warm-pressed by all-round isostatic pressure and the compact produced is further treated, especially by extrusion. To form a tubular compact, the sheath filled with powder (3) is centrally holed (bore 26) by a spike (4, 5) at the same time as the powder (3) is radially pressed from the inside to the outside, after the sheath has been closed (lid 9; 9'; 9'') and subjected to isostatic pressure. The sheath is composed of a cylindrical outer casing (8), a bottom part (14) and a lid (9; 9'; 9'').

Title: Thread-cutting device for zig-zag sewing machines
IPC: D05B65/02
Filed: 1988-04-19
Granted: 1992-09-30
Abstract: The blade (28) of the thread-cutting device is movable in a plane parallel to the thread catcher (33) and connected by a drive (45 to 58) provided with stopping sections (54, 55) with the drive of the thread catcher (33) in such a way as to be movable with the latter as far as the cutting position below the center of the eye of the needle. While the blade (25) of the thread-cutting device remains stationary in the cutting position, the thread catcher completes the thread-cutting operation. The blade (28) of the thread-cutting device moves back during the backward movement of the thread catcher (33) only after the threads have been cut. The drive (45 to 58) for the blade (28) of the thread-cutting device functions by interlocking engagement, which ensures reliable sectioning even of thick threads.

Abstract: Procédé de fabrication de dispositifs de circuit CMOS sur un substrat (26) isolant, dans lequel un procédé d'épitaxie en phase solide est appliqué à des îlots (28, 30), pour les dispositifs indivuduels dans la même étape que les implants (8, 10) dopants de canaux. Une espèce d'ions (12), de préférence du silicium pour un îlot de silicium, est implantée dans chaque îlot (28, 30) à une énergie et un dosage suffisants pour rendre amorphe une couche noyée de l'îlot à proximité d'un substrat (26) isolé sous-jacent; on emploie de préférence du silicium-sur-saphir (SOS). Les couches noyées sont ensuite recristallisées, en utilisant des parties non amorphes de l'îlot semi-conducteur comme graines de cristallisation. Des îlots de matériau semi-conducteur de haute qualité généralement uniforme sont ainsi obtenus, lesquels utilisent plus efficacement des implants dopants, et évitent les transistors parasites de l'art antérieur et les courants de fuites. En implantant l'espèce d'ions à une profondeur plus grande que l'épaisseur d'îlot nominal pour des dispositifs de canaux n, et à une profondeur inférieure à l'épaisseur d'îlot nominal pour des dispositifs de canaux p, la fuite de courant du canal arrière est réduite alors que l'auto-dopage indésirable de l'aluminium est évité pour les dispositifs de canaux p.
