Patent CA-2393007-A1 (CA)
Inventor: DENBAARS STEVEN
IPC: H01L25/075
Filed: 2000-11-20
Abstract: This invention describes new LED structures that provide increased light extraction efficiency. The new LED structures include arrays of electrically interconnected micro-LEDs (12) that have an active layer (14) sandwiched between two oppositely doped layers (16, 18). The micro-LEDs are formed on a first spreader layer (18) with the bottom layer (16) of the micro-LEDs in contact with the first spreader (18). A second spreader layer (24) is formed over the micro-LEDs (12) and in contact with their top layer (16). The first spreader layer (18) is electrically isolated from the second spreader layer (24). Each of the spreader layers (20, 24) has a contact (22, 26) and when a bias is applied across the contacts (22, 26), currents spreads to the micro-LEDs (12) and they emit light. The efficiency of the new LED is increased by the increased emission surface of the micro-LEDs (12). Light from each of the micro-LEDs active layer (14) will reach a surface after travelling only a short distance, reducing total internal reflection of the light. Light extraction elements (LEEs) (82, 84, 86, 88, 90, 92, 94) between the micro-LEDs (12) can be included to further enhance light extraction. The new LEDs are fabricated with standard processing techniques making them highly manufacturable at costs similar to standard LEDs.

Abstract: An apparatus and method for sealing the tail (T) of a rolled product (L) against the rolled product. After being positioned in a location upon a roll er (36), the rolled product is rotated between the roller and a conveyor assemb ly (6) until a jet (44) blows the unsealed tail against the roller. By further rotating the roller, a sensor detects the location of the tail end for determining tail length in later operations. The roller is reversed to pass the tail around the roller and preferably to a tail support (40) adjacent th e roller. When the tail reaches a desired position along the tail support, an applicator sensor (52) sends a signal to an adhesive assembly (42) which applies adhesive to the tail and/or the rolled product. After the adhesive h as been applied, the roller is again reversed to roll the tail back upon the rolled product. The rewound rolled product is then preferably rolled over at  least one ironing roller (172).

Title: Probe tip alignment for precision liquid handler
Inventor: NORTON ROBERT
IPC: G01N35/10
Filed: 2001-12-31
Abstract: A probe drive system (24) of a precision liquid handler (20) sequentially inserts probe tips (36) of a multiple probe array (30) into a locator well (76) at a known position on a locator bed (28). The position of each probe tip (36) is determined by driving the probe tip (36) into contact with points on the side wall (88) of the locator well (76) and sensing the contacts. The positions of the probe tips (36) are mapped and checked for skew of the probe array (30). The probe tip positions ae overlaid to determine probe tip scatter. If a probe tip (36) is excessively misaligned, it is inserted into the locator well (76) and driven against the side wall (88) to bend the probe and reduce the misalignment of the probe tip (36). The center of the probe tip scatter is determined and is used by the probe drive system (24) as a global correction factor. Probe tips (36) with known positions are inserted into spaced apart locator wells (78,80) to detect skew of the locator bed.

Title: Oil pressure control mechanism for automatic transmission
Inventor: YOSHIDA YOSHIHIRO
IPC: F16H61/02
Filed: 2002-10-29
Abstract: In the case of a vehicle for running on wasteland that includes an automatic transmission for performing speed change by connection/disconnection of an oil hydraulic clutch provided alongside each speed change gear or the like vehicles, at the time of use on a wild ground, it is impossible to step on the brake, depending on the posture of the driver, so that it may be impossible to achieve creep prevention with a creep preventive mechanism dependent on a brake signal. Therefore, a creep preventive mechanism independent from a brake signal is required.   An oil pressure supply source for an oil hydraulic clutch is provided with a linear solenoid valve for supplying a working oil or interrupting the supply of the working oil, and the supply of the working oil to clutches is interrupted when the vehicle is stopped under an idling condition of an internal combustion engine.

Title: Process for producing catalyst-coated membranes and membrane-electrode assemblies for fuel cells
Inventor: SEIPEL PETER
IPC: H01M8/10
Filed: 2003-02-28
Abstract: The present invention provides a continuous process for producing catalyst-coated polymeric electrolyte membranes and membrane electrode assemblies for fuel cells. The process of the invention uses an ionomer membrane having a polymeric backing film on the back side. After the first coating step, the membrane is dried, during which the residual solvent may be almost completely removed. After this, the polymeric backing film is removed and the back side of the membrane is coated in a second step. The front and back sides of the membrane can be coated by various methods, such as screen printing or stencil printing. Two gas distribution layers are applied to the two sides of the catalyst-coated membrane to produce a 5-layer membrane electrode assembly. The membrane electrode assemblies are used in polymeric electrolyte membrane fuel cells and in direct methanol fuel cells.

Title: Method for controlling deflection and/or position of a deflection-compensated doctor beam
Inventor: MAKINEN JUKKA
IPC: D21H25/10
Filed: 2001-09-17
Abstract: The present publication discloses a method for controlling the deflection and/or position of a deflection-compensated doctor blade support beam relative to web such as a paper or paper-board web. The invention is based on dividing the movement range of the doctor blade support beam, that is, the spatial range within which the reference point of the support beam can be moved with the help of the compensation elements, into radial control sectors so that the working directions of the compensation elements essentially form the interface limits of the radial control sectors. When it is desired to move the support beam, a set point is selected toward which the reference point of the support beam should move. After the position of the set point is established, the specific control sector is determined within which the set point is located and the thus identified control sector is selected as the active control sector. For the control operation are selected those two compensation elements whose working directions are essentially parallel to the limit vectors of the active control sector. The control of the deflection and/or position of the doctor blade support beam is performed through employing these two compensation elements for adjusting the deflection and/or position of the doctor beam so that one of the compensation elements is used for controlling the deflection and/or position of the support beam in the x-axis direction of the coordinate system, while the other compensation element is used for controlling the deflection and/or position of the support beam in the y-axis direction of the coordinate system.

Abstract: A multi-level locking hierarchy for a relational database includes a first locking level applied to a multi-dimensionally clustering table, a second locking level applied to blocks within the table, and a third locking level applied to rows within the blocks. The hierarchy leverages the multi-dimensional clustering of the table data for efficiency and to reduce lock overhead. Data is normally locked in order of coarser to finer granularity to limit deadlock. When data of finer granularity is locked, data of coarser granularity containing the finer granularity data is also locked. Block lock durations may be employed to ensure that a block remains locked if any contained row remains locked. Block level lock attributes may facilitate detection of at least one of a concurrent scan and a row deletion within a block. Detection of the emptying of a block during a scan of the block may bar scan completion in that block.
