Title: Quadrature modulation circuit for use in a radio transmitter
Inventor: OSAKA MASAHIKO
IPC: H03L7/185
Filed: 1993-08-24
Granted: 1996-11-05
Abstract: A quadrature modulation circuit is comprised of two frequency generators which generate a first frequency signal and a second frequency signal, respectively, and a mixer which mixes the first frequency signal and the second frequency signal to generate the carrier wave whose frequency is different from both the first frequency and the second frequency.  By the quadrature modulation of this carrier wave according to a baseband signal, a transmission wave can be obtained.  Since the first frequency differs from the carrier frequency and the second frequency differs from both the carrier frequency and the first frequency, the output signals of the frequency generators are not affected by the transmission wave.

Title: Polystyrene foam and process for making the same
Inventor: DALKE BRIAN D
IPC: C08J9/228
Filed: 1993-04-12
Granted: 2006-11-21
Abstract: An improved polystyrene foam having less corrugation is disclosed which uses carbon dioxide as the blowing agent and 1-30 weight percent endothermic agent, such as water, with the weight based on the total carbon dioxide blowing agent and endothermic agent weight. This combination of carbon dioxide and endothermic agent decreases the corrugation of the thermoplastic foam, while just slightly increasing density, when the process parameters, including throughput, are equivalent to using only carbon dioxide. The process also allows an increased foaming temperature and greater process throughput of an equivalent density thermoplastic foam at approximately equivalent corrugation levels when compared to the use of only using carbon dioxide.

Abstract: A can opener having a housing, a cutting blade, a can moving system, and a lid retainer. The cutting blade is movably connected to the housing between a cutting position and a retracted position. The lid retainer is pivotably connected to the housing between a recessed position in a recess of the housing and an extended position. The cutting blade is located in front of the recess when it is in its retracted position to keep the lid retainer in the recess. However, when the cutting blade is moved to its cutting position, the cutting blade is moved out of the path of the recess to allow the lid retainer to move from its recessed position to its extended position. The cutting blade can also push the lid retainer back to its recessed position when the cutting blade is moved back to its retracted position.

Filed: 1993-11-18
Granted: 2004-06-08
Abstract: A metal pipe and method of forming the same with an integrally formed liner (16) for use in corrosive and abrasive environments is disclosed. The liner (16) is comprised of a relatively thick high density polyethylene which is thermally bonded to the metal pip e. An intermediate coextruded polymer layer of ethylene acrylic acid and a polyeth ylene/ethylene acrylic acid blend is applied to the meta l pipe to facilitate thermal bonding. The intermediate layer (11) is applied to the sheet metal in a pre-treatment process prior to roll fo rming ribs (12) into the sheet metal. The polyethylene liner (16) is applied after the ribs (12) are formed to provide a smooth, hydraulically efficient surface which is resistant to the corrosive action of sulfuric acid and the like encountered in sanitary applications, as well as ab rasion caused by the flow of water-borne debris such as dirt and gravel as is encountered in culvert applications. Various means for further secur ing the polyethylene layer to the metal pipe surface are disclosed.

Title: Systeme hydraulique pour faire avancer un vehicule et pour le diriger

IPC: F15B13/02
Filed: 1995-05-04
Granted: 2005-09-13
Abstract: Les unités des roues avant et arrière (13, 14) du véhicule sont reliées ensemble par un joint d'articulation ce qui permet de diriger le véhicule. Les roues d'au moins une unité peuvent pivoter par rapport à cette dernière, ce qui permet de diriger le véhicule en plus par pivotement des roues. Une première forme d'exécution permet de diriger le véhicule manuellement, par articulation du véhicule et par pivotement des roues, de manière indépendante. Dans une seconde forme d'exécution, un intégrateur de commande de direction coopère avec des dispositifs d'actionnement (162, 163, 212, 213, 236, 237) commandant l'articulation du véhicule et le pivotement des roues avant (22, 23), en faisant en sorte qu'il y ait automatiquement cohérence entre les deux modes de commande de la direction, en particulier entre l'angle d'articulation de l'unité avant (13) et l'unité arrière (14) d'une part et l'angle de pivotement des roues avant (22, 23) par rapport à l'unité avant (13) d'autre part. Une commande manuelle de la direction, par exemple un volant (186), assure la commande de l'intégrateur de commande. Chaque roue est entraînée par un moteur hydraulique (32, 33, 44, 45) recevant un fluide sous pression d'un appareil d'entraînement comprenant un collecteur de fluide et deux réducteurs de débit montés en parallèle et communiquant avec les sorties des moteurs des roues. On peut utiliser des vannes de court-circuit (114, 115) pour court-circuiter le collecteur de fluide et les réducteurs de débit, lorsque cela est utile, dans certaines applications ne nécessitant pas de collecteur de fluide, ceci afin de diminuer l'échauffement du fluide hydraulique.
