Abstract: For trimming an archway, a drywall-trimming has a nose with an outer surface and an inner surface. The outer surface has a curved portion conforming substantially to an arcuate profile with a radius in a range from approximately 1/4 inch to approximately 3/4 inch. The drywall-trimming strip has a series of slits defining a series of tabs spaced from one another along a tabbed edge but not extending into the nose. Near the tabbed edge, the slits have widened, oblong portions. Usually, the drywall-trimming strip has a flange extending from and along an opposite edge, but the flange is omitted for some applications. A comparatively softer portion, which includes the juncture where the tabs are joined to the tabbed edge, is made from a comparatively softer, more flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer 92 Shore A. A comparatively harder portion, which includes the flange and at least a substantial portion of the nose along the flanged edge, is made from a comparatively harder, less flexible, polymeric material, such as polyvinyl chloride having a hardness of Durometer Shore 82 D. In one contemplated embodiment, the comparatively harder portion includes at least substantially all of the nose, except for the juncture where the tabs are joined to the tabbed edge of the nose. In another contemplated embodiment, each of the comparatively harder and comparatively softer portions includes a substantially equal portion of the nose. The comparatively softer portion may include the entire tabs or substantially all of the tabs are made from the comparatively harder material except for the juncture where the tabs are joined to the tabbed edge of the nose. Because the comparatively softer portion includes the juncture where the tabs are joined to the tabbed edge of the nose, the outer surface of the nose of the drywall-trimming strip tends to continue to conform substantially to an arcuate profile, even after the drywall-trimming strip has been curved so as to conform to an archway.

Abstract: A feed forward amplifier with digital intermodulation control (214) includes an up-converter (219), a feed forward amplifier (150), a down-converter (230), and a digital intermodulation controller (214). The up-converter (219) receives a first digital input (218) and generates an analog composite signal (140) and a reference frequency signal (221). The feed forward amplifier (150) receives the analog composite signal (140) and produces an amplified analog composite signal (147) and an amplified analog composite signal sample (126).  The down-converter (230) mixes the amplified analog composite signal sample (126) with the reference frequency signal (221) in a mixer (216) to produce an adjusted amplified analog composite signal sample (128) which is then converted to a second digital input (226) via an analog-to-digital converter (215). A digital intermodulation controller receives a first and second digital input (218, 226) and subsequently generates a phase and gain adjuster input (224, 225) for adjusting the feed forward amplifier (150).

Title: Bus switch and bus switch system
Inventor: KAGANOI TERUO
IPC: G06F13/36
Filed: 2000-11-03
Granted: 2005-08-09
Abstract: In the bus switch system of the invention, with the adapter, the first input and first output registers in cascade connection on the data transferring bus of bus switch compose a shift register.      Also, with the bridge, the second input and second output registers in cascade connection on the first data transferring bus compose a shift register. This allows data to be transferred to the adjacent adapter at one clock cycle, thereby the clock rate in data transfer is made faster. Also, the data transfer on the first and second data transferring buses is conducted in one direction and the input/output control is optimally conducted by the first and second control means. Thereby, the switch control in data transfer is made easier.

Abstract: L'invention concerne une membrane (8) servant de substrat de captation dans un filtre électrostatique. Cette membrane peut être constituée de fibres sous forme de mats tissés, d'écrans constitués de fils en acier inoxydable ou de membranes composites polymères renforcées de fibres. Ces membranes subissent une contrainte de traction (14) pendant le fonctionnement ainsi qu'une résistance à la traction par impulsion pendant une étape de dépoussiérage. La combinaison d'un champ de membrane de filtre électrostatique sec et d'un champ de nettoyage à film humide permet d'améliorer l'efficacité de captation en réduisant la turbulence et en éliminant les pertes de réentraînement dues à l'ébranlage. En mettant en oeuvre de nouvelles matières qui résistent aux environnements hostiles des dépoussiéreurs électrostatiques, l'invention augmente les possibilités d'utiliser de nouvelles techniques, telles que l'impulsion de couronne et analogues indiquées pour la suppression de molécules telles que les oxydes d'azote et de soufre, ce qui est important pour être conforme aux règlements PM2.5 EPA proposés sur les émissions.

Abstract: A rotary cone bit, having a functionally-engineered surface of this invention, comprises a bit body having at least one leg extending therefrom, and a cone that is rotatably disposed on the leg. The cone typically comprises a plurality of cutting elements that project outwardly therefrom. The cutting elements comprises a cermet material selected from the group consisting of refractory metal carbides, nitrides, borides, carbonitrides and mixtures thereof. A functionally-engineered material is disposed over a surface portion of at least one of the cutting elements to form a wear resistant surface thereon. The wear resistant surface has a hardness that is different than that of the underlying cutting element. The wear resistant surface is provided by forming a conformable material mixture by combining one or more powders selected from the group consisting of cermets, carbides, borides, nitrides, carbonitrides, refractory metals, Co, Fe, Ni, and combinations thereof, with an applying agent. The applied material mixture is pressurized under conditions of elevated temperature to consolidate and sinter the material mixture, thereby forming the wear resistant surface. The material mixture is consolidated and sintered in a manner that avoids unwanted material migration between the applied material mixture and substrate, thereby providing a fully-densified wear surface having desired properties of hardness and/or fracture toughness.
