Filed: 1992-01-31
Granted: 2001-05-15
Abstract: Une famille logique parallèle à entrée logique complémentaire à haute vitesse et faible capacitance (CLIP) comprend un étage de commande d'un transistor à effet de champ FET (11), un inverseur FET complémentaire (14), et au moins un FET de déclenchement (13a-13b). Les dimensions du FET (13) de déclenchement sont déterminées par rapport aux dimensions des transistors à effet de champ FETs (11a-11f) de l'étage de commande pour obtenir un circuit logique à haute vitesse. Des circuits logiques ET et OU CLIP peuvent être obtenus. Un circuit logique CLIP synchronisé peut être obtenu en ajoutant un transistor FET de synchronisation. Un circuit logique CLIP synchronisé de verrouillage peut également être obtenu en ajoutant un transistor FET de verrouillage. Dans le circuit logique CLIP synchronisé de verrouillage, la sortie de la porte est verrouillée de sorte qu'il ne change pas pendant la période de synchronisation indépendamment des modifications des entrées logiques du circuit. La vitesse des circuits logiques CLIP peut encore être accrue en incorporant du germanium dans le canal de ses transistors FETs à canal P de manière à augmenter la mobilité porteuse dans les transistors FETs à canal P. Les transistors FETs à canalN n'ont pas de germanium. La capacitance interne des circuits logiques CLIP est diminuée en utilisant des régions communes de diffusion dans le circuit intégré pour des pairs de transistors FETs de l'étage de commande. Des régions de diffusion de source commune et/ou de drain commun peuvent être utilisées.

Abstract: An acoustic displacement flowmeter determines the flow rate of a fluid in a path containing a controllable valve by establishing fluid flow along the path, directing the flow of the fluid to a transducer having a displacement element by restricting the flow path, generating a signal from the transducer representative of displacement due to fluid flow while the flow path is restricted, using the transducer to determine the fluid flow rate, and reestablishing fluid flow along the path by removing the restriction. The transducer signal is used to determine the fluid flow rate by providing an analog reference signal, integrating the analog reference signal for a predetermined time period, deintegrating the integrated reference signal with the transducer signal until the value of the deintegration signal reaches a threshold value, and using the time required for the deintegration signal to reach the threshold value to calculate the flow rate. The time is accumulated by counting the number N of fundamental sampling periods occurring during the deintegration of the integrated reference signal and determining the flow rate from the equation V = A/N-B, where V is the mass flow rate and A and B are constants. A temperature correction signal for adjusting the calculated flow rate value for temperature variations is generated by providing first and second sensor signals whose ratio is representative of temperature, integrating the first sensor signal for a predetermined time period, deintegrating the integrated first signal with the second sensor signal until the value of the deintegration signal reaches zero, and using the time required for the deintegration sensor signal to reach zero to calculate the temperature correction signal.

Abstract: Detachable chevron-shaped panels that fit within chevron-shaped apertures in the cover of an exit sign.  The panels are dimensioned to fit integrally into the apertures in order to withstand years of stress, temperature changes, and wear and tear but continue to perform in a light-fast and reliable manner.  Yet they may be easily installed from the exterior of the exit sign, with minimum risk that they will fall into the interior during installation.  Surprisingly, the present invention permits such easy installation without the need to use conventional "slide 'n' snap" exit sign arrow fasteners that usually allow reliable installation but have proven to be destructive of a secure fit and light fastness.  The panel accomplishes this by employing at least three tabs positioned in a certain manner about the perimeter of each wing of the panel which engage the (preferably bevelled) edge of the chevron-shaped aperture.   The tabs are disposed in various quadrants around the centroid of each wing of the panel in order to create an integral fit of the long chevron wings to the cover and thus to reduce inadvertent detachment of the whole panel if a part of it is dislodged, or if the cover is deformed through heat or physical stress.  Such positioning also provides multiple retention axes between tabs and creates lateral forces and bending moments, should any tab become dislodged, in order to continue securing the wing and the panel in place.

Granted: 2000-06-13
Abstract: A check valve mechanism is disclosed for a twin tower gas drying system.   The drying system filters unpurified gas to supply purified gas to a pneumatic system.  The purified gas is supplied alternately from each tower to the mechanism for distribution in an output percentage to the pneumatic system and in a purge percentage to the drying system for purging moisture previously collected.  The mechanism includes a valve body and a shuttle choke.  The body defines first and second channels  connected  to  the   first  and  second  towers, respectively;  a shuttle tube having first and second ends connected to the first and second channels, respectively; and an output passage having an initial end communicating with the pneumatic system and a terminal end communicable with the tube.          The choke defines an orifice and slides between the ends.  When purified gas flows from the first tower, the choke slides to the second end.   Purified gas flows from the first tower through the first channel through the output passage in the output percentage to the pneumatic system and through the orifice in the purge percentage through the second channel for purging via the second tower.  When purified gas flows from the second tower, the choke slides to the first end.  Purified gas flows from the second tower through the second channel through the output passage in the output percentage to the pneumatic system and through the orifice in the purge percentage through the first channel for purging via the first tower.
