Patent CA-2171188-C (CA)
Inventor: ZOOK JAMES DAVID
IPC: G01P15/097

Abstract: Une jauge de contrainte résonante comprend un substrat de silicium, une flèche de flexion en polysilicium fixée aux deux extrémités du substrat, et un couvercle rigide en polysilicium coopérant avec le substrat pour enfermer la flèche de flexion dans une chambre à vide scellée. Une électrode de polarisation supérieure est formée sur le couvercle et une électrode de polarisation inférieure est formée sur le substrat directement en-dessous de la flèche de flexion et espacée par rapport à cette dernière. Une électrode d'attaque est formée dans la flèche ou sur la flèche, centrée entre les électrodes de polarisation supérieure et inférieure, transversalement par rapport à la direction d'allongement de la flèche. Les électrodes supérieure et inférieure sont polarisées à des niveaux de tension constants, d'intensité identique et de polarité opposée. L'électrode d'attaque, généralement polarisée à la terre, est chargée sélectivement en appliquant une tension d'attaque oscillatoire afin de provoquer l'oscillation mécanique de la flèche. Un élément de piézorésistance, formé sur la flèche, détecte l'oscillation de la flèche et fournit un signal d'entrée d'indication de position au circuit oscillateur qui excite la flèche. La flèche tend à osciller à sa fréquence de résonance naturelle. La piézorésistance fournit ainsi la fréquence de résonance naturelle au circuit oscillateur, ajustant la fréquence du signal d'attaque de la flèche pour la faire coïncider avec la fréquence de résonance naturelle. Une électrode de protection peut être formée sur la flèche de flexion entre la piézorésistance et l'électrode d'attaque pour assurer une protection contre les capacitances parasites. Dans d'autres modes de réalisation, le signal d'attaque est appliqué à l'une des électrodes de polarisation pour faire osciller la flèche, puis l'oscillation de la flèche est détectée de manière capacitive.

Title: Improved process and apparatus for producing non-woven webs
Inventor: LU FUMIN
IPC: D01D5/12
Filed: 1996-08-12
Granted: 2009-02-24
Abstract: A process for producing a non-woven polymeric fabric web, such as a spunbond web, having filaments of 0.1 to 5 denier with equivalent production rates is described. A plurality of continuous polymeric filaments (F) is extruded from an extruder (22) and attenuated by a drawing unit (31) that includes a longitudinal elongated slot (32) strategically positioned at an optimum distance very close to the spinneret (26). A web forming table (90) is positioned below the drawing unit for collecting the filaments and forming the filaments into a non-woven fabric web. At startup, throughput is nominal, air pressure is below 20 psig, and the spinneret is positioned more than 100 cm away from the drawing unit. Gradually, throughput is greatly increased by simultaneously increasing air pressure while reducing the distance between the spinneret and the drawing unit. Coordinating the adjustment of the throughput with air pressure and distance reduction of the spinneret and the drawing unit produces the finest filaments at equivalent production or the same filament size at the highest production rate and lowest cost.
