Abstract: L'introduction d'une activité de phosphorylase du sucrose dans des plantes par transformation au moyen d'un gène pour cette enzyme accroît la vitesse d'hydrolyse du saccharose, ce qui se solde par une augmentation des concentrations d'amidon, d'huile et de protéines. Le gène préféré dans le cadre de cette invention est issu du Streptococcus mutans. Curieusement, dans des pommes de terre transformées pour que s'exprime ce gène dans les tubercules, on note une tendance réduite à l'altération de la coloration due à des meurtrissures tandis que l'on remarque un dépôt d'amidon plus uniforme sur tout le tubercule.

Abstract: The invention relates to a gas turbine seal structure between end portions of a moving blade platform and a stationary blade inside shroud,  in which a sealing performance is improved by increasing a resistance  of a flow.  A seal plate (21, 31) is mounted to an end portion of a platform (2, 2') of a moving blade (1) and a seal portion is constituted by a seal fin (22, 32) and a honeycomb seal (16,  17) disposed to a lower surface of an end portion (12a,  12b) of an inside shroud (12) of a stationary blade (11).  A sealing air from the stationary blade (11) produces a high temperature in a cavity (14) and is flown into a space (18, 19),  and also an air leaked from a cooling air of the moving blade (11)  is going to escape to a high temperature combustion gas passage from the space (18,  19) through a seal portion, however, since three seal fins (22, 32) of the seal plate (21, 31) are inclined in such a manner as to oppose to the air flow,  the air resistance is increased and the flowing-out of the air is prevented.  Accordingly,  a sealing performance is improved in comparison with the conventional structure having no seal fin (22, 32).

Abstract: A method and apparatus for performing a lens calibration procedure which is executed for each camera and lens pair. The calibration procedure is performed to determine the camera and lens nodal point offset and field of view, plus image offset in both the horizontal and vertical directions as a function of lens zoom and focus settings. The method includes the step of providing apparatus which enables the semi-automatic and rapid entry of data points representing lens zoom and focus setting information, thereby eliminating a source of human error. The general method includes the steps of creating a real environment and an identical virtual environment which is a copy of the real environment. The image from the virtual environment is superimposed on a monitor displaying the real environment. The camera's zoom and focus rings are incremented through a plurality of values by discrete steps. For each value, the virtual environment's settings are manipulated until the real and virtual images are identical. The values from the virtual environment are then recorded as a data point corresponding to a specific camera lens zoom and focus setting. A plurality of data points are then recorded to create the calibration dataset.

Title: Drug-releasing coatings for medical devices
Inventor: TRINH TUYETHOA THI
IPC: A61F2/82
Filed: 1998-04-28
Granted: 2005-01-25
Abstract: The invention is directed to medical devices having a drug-releasing coating and methods for making such coated devices. The coating permits timed or prolonged pharmacological activity on the surface of medical devices through a reservoir concept. Specifically, the coating comprises at least two layers: an outer layer containing at least one drug-ionic surfactant complex overlying a reservoir layer containing a polymer and the drug which is substantially free of an ionic surfactant. Upon exposure to body tissue of a medical device covered with such coating, the ionically bound drug in the outer layer is released into body fluid or tissue. Following release of such bound drug, the ionic surfactant binding sites in the outer layer are left vacant. To maintain the pharmacological activity after delivery of the ionically bound drug, additional amounts of the drug are embedded or incorporated in the reservoir layer in a manner which allows the drug, which is substantially free of ionic surfactants, to complex with the vacant binding sites of the ionic surfactant of the outer layer. As a result, the surface of the medical device is enriched with the drug to provide sustained pharmacological activity to prevent the adverse reaction due to the presence of the medical device. The invention is further directed to medical devices with stabilized drug-releasing coatings. The coatings are stabilized by exposure to a low energy, relatively non-penetrating energy source, e.g., gas plasma or an electron beam energy source.

Abstract: The present invention provides an antenna system, which is used for a mobile wireless device and can be accommodated in or withdrawn from a telephone set main unit, whereby element length is shortened and strength is increased while avoiding deterioration of characteristics when the antenna is accommodated in the telephone set main unit. The antenna (40) comprises a helical antenna (41) having a feeding unit (42) and a whip antenna (43) having a feeding unit (44). The whip antenna (43) passes through the helical antenna (41), and the helical antenna (41) and the whip antenna (43) are electrically insulated from each other. Because the whip antenna (43) is designed to pass through the helical antenna (41), an antenna system for mobile wireless communication can be provided, in which element length is shortened and strength is increased.

Abstract: A vehicle brake includes a compact module having an inlet port connected to the return-to-sump line of a hydraulic operating system on the vehicle. The module includes a path to a filter mounted on the module for filtering the operating system fluid and a poppet valve for bypassing a clogged filter. Passages in the module direct most of the return line fluid through a poppet valve which develops a source of back pressure substantially lower that system operating pressure in a cavity in the module and returns the fluid to an outlet connected to sump. A portion of the fluid in the cavity is communicated via a charge port in the module to a hydrostatic system to replenish leakage and shuttle flow in the hydrostatic system and to prevent cavitation. The source of back pressure in the module is selectively connected to spring-applied, pressure-released brakes through a four-way solenoid valve housed by the module. To release the brakes, the valve is actuated to direct pressure to one side of each of the brake cylinders. To apply the brakes, the valve is deactuated to pressurize the opposite sides of the cylinders for hydraulically assisted braking.

Abstract: There are provided two line monitoring resistors 63a, 63b of high resistance (Rt1, Rt2) branched at nodes 64a, 64b from subscriber line (LN) 3 in line circuit (LC) 4 and connected between each node and earth, and arithmetic operation unit (EP) 60 into which terminal voltages Vt1, Vt2 of line monitoring resistors 63a, 63b are inputted. Arithmetic operation unit 60 monitors Vt1, Vt2 for a predetermined time when subscriber terminal 2 is in on-hook, and hence detects unbalance of DC voltage of both lines and voltage induced on subscriber line 3 to estimate line resistance. When the subscriber terminal is off-hook, line resistance of the line is estimated using a difference between a theoretical value of Vt1, Vt2 when the line is open and silent and a corrected value in a silent state when the sound component is removed.

Granted: 2006-04-18
Abstract: A non-uniform memory access (NUMA) computer system includes at least a local processing node and a remote processing node that are each coupled to a node interconnect. The local processing node includes at least a processor and a local system memory, and the remote processing node includes at least a processor having an associated cache memory, a local system memory, and a node controller that are each coupled to a local interconnect. In response to receipt by the node controller of a request transaction transmitted from the local processing node via the node interconnect, the node controller at the remote processing node issues the request transaction on the local interconnect. If the request transaction receives a retry response at the remote processing node, the node controller does not immediately return the retry response to the local processing node. Instead, the node controller reissues the request transaction on the local interconnect at least once, thus giving the request transaction another opportunity to complete successfully. In one embodiment, the request transaction is reissued on the local interconnect of the remote processing node until a response other than retry is received or until a retry limit is reached.
