Abstract: Un système d'éléments pour la constitution de dispositifs de serrage comporte une pièce de base (1) s'étendant dans un plan X-Y, et au moins une pièce de serrage (2) pouvant être fixée sur la pièce de base en différentes positions sélectionnables. La pièce de base (1) possède dans le plan X-Y des proéminences (6) disposées régulièrement selon une trame avec des faces de référence (6a et 6b) agissant dans le sens Z. Le cas échéant, des éléments de fixation s'étendent entre les proéminences (6) et la pièce de serrage (2). Soit la distance entre des faces de référence de proéminences voisines et la distance des faces de référence sur une proéminence est égale, soit la distance entre des faces de référence de proéminences voisines est un multiple pair de la distance des faces de référence sur la même proéminence. On obtient ainsi une grande souplesse d'utilisation du système d'éléments, tout en ayant des possibilités de serrage fiables et faciles.

Abstract: A widescreen television picture is sampled at a higher sampling rate so as to fit all of the information in the current 52.5 us active video line time. A selection signal is also incorporated with the widescreen picture signal, allowing non-widescreen television receivers to display a contiguous portion of the widescreen picture without geometric distortion. The widescreen television signal is transmitted either in MAC or widescreen NTSC format, and is received by a decoder. The decoder allows the entire widescreen picture to be displayed on a widescreen receiver, and makes use of the selection signal to display the selected portion of the picture on a standard receiver without geometric distortion. In another embodiment, a decoder allows television signals having the standard aspect ratio to be displayed on receivers having widescreen aspect ratios without geometric distortion.

Abstract: A method for programming a two-level polysilicon EEPROM memory cell, which cell is implemented in MOS technology on a semiconductor substrate (2) and comprises a floating gate (12) transistor and a further control gate (15) overlying the floating gate (12) with a dielectric layer (11) therebetween, provides for the application of a negative voltage to the control gate (15) during the cell (1) write phase. This enables the voltages being applied across the thin tunnel oxide layer to be distributed so as to reduce the maximum amount of energy of the "holes" and improve the oxide reliability. In addition, by controlling the rise speed of the impulse to the drain region during the write phase, and of the impulse to the control gate during the erase phase, the maximum current flowing through the tunnel oxide can be set and the electric field being applied to the tunnel oxide kept constant, thereby the device life span can be extended.

Filed: 1993-01-27
Abstract: Certaines caractéristiques opérationnelles d'un cristal (104) sont mesurées lors d'un procédé d'essai et d'étalonnage. Une fois déterminées, les informations représentant ces caractéristiques opérationnelles sont stockées dans une mémoire (120) et sont utilisées par un contrôleur (122) pour incrémenter un registre à incrément de phase (114) par détermination de la température ambiante du cristal à l'aide d'un circuit de détection de température (124). La valeur stockée dans le registre d'incrément de phase (114) est ensuite envoyée à un accumulateur de phase (116) où les incréments de phase successifs sont additionnés. Cette valeur additionnée est à son tour envoyée à une table de consultation de sinosoïde (118) où la valeur de phase instantanée est convertie en amplitude sinusoïdale. Finalement, un convertisseur numérique/analogique (126) convertit la chaîne de bit d'amplitude en un signal analogique pour être utilisé comme fréquence de référence d'oscillateur ayant une résolution de fréquence extrêmement élevée. Le procédé susmentionné est répété à chaque cycle d'horloge jusqu'à ce qu'une onde sinusoïdale complète soit produite, moment auquel l'accumulateur de phase est remis à zéro et le procédé recommence.
