Title: Excitation de capteurs de pression a base de polysilicium
Inventor: FUNG CLIFFORD D
IPC: G01L9/00
Filed: 1995-12-15
Granted: 2003-12-30
Abstract: Le but de l'invention est d'éliminer un comportement transitoire à long terme quand un silicium polycristallin est soumis à une excitation électrique et à produire une excitation électrique, dont la période de stabilisation et la consommation de puissance sont réduites au minimum. L'invention concerne un circuit d'excitation électronique pour un capteur en silicium polycristallin qui détecte la pression dans un déroulement de processus. Ce capteur est constitué par des capteurs piézorésistifs en silicium polycristallin (22) déposés sur une membrane de détection en silicium polycristallin (14), une couche diélectrique (18) étant interposée entre lesdits capteurs et ladite membrane. L'excitation électrique des capteurs piézorésistifs s'effectue au moyen d'une onde électrique de courant alternatif possédant une amplitude constante inférieure à 10 volts et une fréquence inférieure à 100 kHz. L'onde est appliquée à une première borne d'entrée (40a) d'un pont de Wheatstone présentant une polarité opposée à celle d'une deuxième borne d'entrée (40b) du pont. On utilise la différence de tension obtenue entre les bornes de sortie afin de détecter un déséquilibre dans les résistances électriques provoqué par la pression appliquée. Le niveau de tension et la plage de fréquence sélectionnés sont tels que la puissance utile du circuit est d'environ 1mW.

Title: A recirculating paint system
Inventor: HOLT EARL R
IPC: B05B9/03
Filed: 1996-07-17
Granted: 2001-11-13
Abstract: A recirculating paint supply system supplies single or multiple paint coating to paint spray stations arranged in parallel or series relation, each station including manually operated flexible monoline and coaxial conduits (102, 104) to supply paint to an improved spray gun (88). In one aspect of the invention, the improved spray gun is comprised of a polymeric material to reduce the overall weight of the spray gun thereby reducing operating fatigue and ailments caused by the use of conventional spray guns. In another aspect, the improved spray gun includes larger air passages (338) which provide for a greater volume of air to pass through the spray gun, thereby providing increased atomization of the liquid coating composition. Thus, the reduced weight, as well as the increased atomization, increases the overall finish quality of the object being painted.

Abstract: A handle assembly of the type used in railway locomotives has been improved. The handle assembly includes a base plate, a cam mount attached to the base plate, a cam disk, and a shaft assembly interconnecting the mount and disk to allow rotation of the disk. The improvement includes a yoke, a bail bar, first and second bearing members anchored to the plate, and first and second switches attached to the plate. Pivotally connected to the disk and accommodating a handle, the yoke rotates along with the disk as the handle is moved along its range of motion and tilts as the handle is moved perpendicularly thereto. The bail bar is rotatable between the first and second bearing members. A first mechanism imparts a rotational force to the bail bar so that its middle section presses against an upper portion of the yoke. A stop limits rotation of the bail bar to a point at which the yoke and handle attain an untilted state. Operating against a lower portion of the yoke, a second mechanism provides a counterbalancing force to normally bias the yoke in the untilted state. No matter where the handle is positioned along its range of motion, when it is tilted by a preset amount, the yoke overcomes the rotational and counterbalancing forces so that a third mechanism causes both the first and second switches to change state.

Abstract: An anode installation apparatus has an pilot auger to which an anode may be attached, plus a cylindrical drive tube which engages the pilot auger when rotated in one direction, such that the drive tube is drawn downward into the ground along with the pilot auger. When the pilot auger has been augered to a desired depth below ground, carbonaceous material may be introduced into the drive tube so as to surround the anode. The drive tube is then rotated in the opposite direction, whereupon it will disengage from the pilot auger and may be pulled out of the ground, and the cavity thus formed in the ground may be backfilled. The drive shaft may be re-used for installation of additional anodes.

Abstract: A method for operating a group of gaming machines interconnected by a network to play both primary and secondary games from the machines. Each of the gaming machines has a primary game associated with it. Play is allowed to occur on the gaming machines while a triggering event is detected. In a preferred embodiment, the triggering event is detected by monitoring an operating parameter of the gaming machines over the network, such as total coins played. A predetermined criterion or threshold is set for the operating parameter and, if the operating parameter meets the predetermined criterion, a triggering event signal is sent through the network. Upon the occurrence of the triggering event, a secondary game is initiated from a selected one of the gaming machines whereby the secondary game is common to the group of gaming machines. The secondary game is most preferably a wheel-of fortune-type game and is displayed in common to all of the machines and local spectators on a plasma-based display monitor of the type marketed by Fujitsu under their Plasmatron TM brand.  Driving the plasma-based monitor is an animation computer that contains software coded animation programs for displaying the wheel-of fortune and related audio/video events responsive to a stand-alone bonus server (SBS).
