Inventor: TAKAHASHI TAKESHI
IPC: B65H5/06
Filed: 1992-07-20
Abstract: A roller supporting structure has a shaft (2) having first grooves (3) for generating a dynamic pressure, and first and second retaining plates (5,6) placed on both sides of a roller (1) when the roller (1) is mounted around the shaft (2). The first and second retaining plates (5,6) have second grooves (7,8) for generating a dynamic pressure on their roller-side end faces. When the roller (1) is placed in an axially central portion of the shaft (2), that is, in the middle between the retaining plates (5,6), there is left a predetermined gap between the roller-side end face of each retaining plate (5,6) and each end face of the roller (1). The gap is large enough for the second grooves (7,8) of the first and second retaining plates (5,6) not to generate the dynamic pressure between these retaining plates (5,6) and the roller (1). The second grooves (7 or 8) of one of the first and second retaining plates (5,6) generate the dynamic pressure when the roller (1) is displaced from the axially central portion toward the one retaining plate (5 or 6).

Abstract: A semiconductor device includes spaced-apart, surface-adjoining, laterally-oriented first and second device regions. A channel region at least partially surrounds the second device region, and a gate region is provided adjacent to, but insulated from, the second device region and the channel region. The gate region extends in a substantially vertical direction adjacent the second device region and the channel region in order to induce a substantially vertical conduction channel in the channel region of the device during operation. The gate region can advantageously be provided in a trench surrounding the transistor device, with a trench-shaped gate dielectric layer being provided on the trench sidewalls and floor to insulate the gate from the remainder of the device. Devices may be fabricated in an epitaxial surface layer, which may be provided either directly on a semiconductor substrate, or else on an intervening insulating layer. These devices provide the advantages of low on-resistance, fast switching speed, high breakdown voltage and high latch up current density.

Abstract: Flexible reaction cuvettes are well known for carrying out reactions, for example, polymerase chain reaction (PCR) amplification. Such cuvettes comprise a plurality of compartments filled with reagents for the reaction, each compartment being sealed from the others. Patient sample is injected into one compartment and is then transferred to a detection chamber by bursting the compartment. However, the presence of air in the detection chamber can reduce the efficiency of the detection. Described herein is a method for forcing liquid out of a burstable compartment (26) into a detection chamber (40) without also forcing residual air of that compartment to interfere with liquid detection. The method features applying pressure sufficient to eject the liquid but not the residual air, and retaining that pressure as long as the reaction period of the liquid takes place and then completing the ejection to eject residual air into the chamber (40).

Abstract: Exhaust gases containing oxides of nitrogen and sulfur from a fired process heater, a fossil fuel fired boiler, or a chemical process are diverted from a stack prior to admission to the atmosphere through a duct system containing heat exchangers that reduce the exhaust gas from an elevated temperature, if any, to about ambient temperature. Any heat extracted from the exhaust gas may be transferred to the boiler feed water which would serve to reduce the energy cost of operating a boiler. Once the exhaust gas is cooled to about ambient temperature, the gas is then mixed with an oxidant, such as ozone, at a preselected molar ratio to transform the oxides to higher orders of nitrogen and sulfur oxides to increase the absorbability of the nitrogen and sulfur oxides in a reagent solution, The reagent absorbs the oxidized contaminants from the exhaust gas. The oxides are transformed to dilute acids which are then neutralized to form salts that are acceptable for discharge to a municipal waste water treatment plant. The treated exhaust gas is then emitted from an exhaust stack containing contaminants at a level meeting air quality standards. Additionally any heat recovered from the exhaust gas can be used to lower operating costs.

Abstract: Tufting apparatus for producing textile goods includes a plurality of hollow needles (10) which are reciprocated vertically to penetrate a backing (12). A selected yarn (92) is fed pneumatically through a respective passageway (102) into a yarn exchanger (70) and through a respective needle and implanted into the backing, the backing being shifted transversely so that a transverse row of tufts is implanted across the backing. There are a series of passageways (102), each carrying a different yarn, communicating with each yarn exchanger. The selected yarn is fed by a yarn feed system and carried by high pressure air flowing in the passageway of the selected yarn, the yarn exchanger and the needle, while air flows in the other passageways under a lower pressure. The yarn exchanger has a funnel shape configuration (108) and when a particular yarn is selected to be fed to the needle, another yarn is withdrawn from the needle to the inlet of the funnel. In order to prevent tangling of yarn within the funnel to preclude clogging at the inlet of the nozzle, an air jet is supplied within the funnel directed toward the inlet of the needle, the air jet being a nozzle (112,114) positioned within the funnel.

Abstract: Procédé de prédiction de la formation pore-pression en avant du trépan de forage (24) lors d'un forage. Pendant le forage, le trépan de forage en contact avec la terre génère un signal séismique. Le signal séismique se propage à partir du trépan de forage de manière radiale, certains rayons se propageant directement vers la surface (16), tandis que d'autres se propageant vers le bas sont renvoyés vers la surface. Les signaux séismiques directs et réfléchis sont reçus par des détecteurs séismiques à un ou plusieurs endroits. Les signaux produits par les détecteurs sont enregistrés pour être traités ultérieurement. A partir des signaux enregistrés, une vitesse d'intervalle pour chaque formation derrière le trépan de forage est déterminée d'une manière très similaire à l'établissement d'un profil séismique vertical. A partir des signaux séismiques réfléchis, une impédance acoustique pour chaque formation au devant du trépan de forage est déterminée. Les résultats de la détermination de la vitesse d'intervalle et les informations d'impédance acoustique sont combinés pour produire une courbe d'estimation d'impédance de type logarithmique qui reflète la formation pore-pression présente dans les unités souterraines en avant du trépan de forage. Ces informations sont utiles à l'ingénieur de forage qui peut estimer le poids de la boue de forage et prévenir ainsi d'éventuelles explosions et des à-coups de pression.
