Inventor: TAKAHASHI SUSUMU
IPC: G02B3/00
Filed: 2002-12-03
Abstract: A lens array sheet capable of controlling horizontal- and vertical-direction viewing angles on a screen without posing problems involving lowered gain (brightness) due to light absorption caused by an excessive use of a light diffusing agent (fine particles) and reduced S/N ratio due to an increase in white scattering; and a transmission screen and a rear projection type displ ay unit using this sheet. A lens array sheet comprising a lens array layer (13b ) including a first lens array (18) and a second lens array (20) that comprise a plurality of semi-cylindrical cylindrical lenses (17, 19) arranged in parall el and are arranged and integrated on the same plane (one surface of a base material layer (13a)) so that the lengthwise directions of the cylindrical lenses (17, 19) cross perpendicularly, and a light shielding layer (16) form ed on the image forming surface side of the lens array layer with its non-light - transmitting portion shielded; and a transmission screen comprising the lens array sheet and a Fresnel lens additionally combined therewith.

Patent CA-2470633-A1 (CA)
Inventor: SHARMA DEVESH
IPC: B01J47/08
Filed: 2002-12-19
Abstract: La présente invention concerne un procédé de traitement de liquide conçu pour un retrait séquentiel d'espèces ioniques de force ionique progressivement décroissante, sans précipitation, ni entartrage. Un mode de réalisation de la présente invention concerne des opérations d'électrodésionisation double. La première opération d'électrodésionisation est réalisée à une tension calculée pour retirer des espèces fortement ionisées, telles que le calcium et le magnésium, de l'eau d'alimentation, sans entartrage. Le produit de la première opération d'électrodésionisation est ensuite soumis à une seconde opération d'électrodésionisation. Cette seconde opération d'électrodésionisation est réalisée à une tension supérieure à celle de la première opération d'électrodésionisation et est conçue pour retirer des espèces plus faiblement ionisées, telle que la silice et le dioxyde de carbone atmosphérique. Cette invention permet d'éliminer le danger constitué par la précipitation ou l'entartrage normalement présent lors d'une électrodésionisation d'espèces faiblement ionisées, en ce que les espèces fortement ionisées responsables de l'entartrage à des tensions supérieures ont déjà été retirées du flux d'alimentation au moyen de la première opération d'électrodésionisation. On peut réaliser plus de deux opérations d'électrodésionisation à la suite si on le souhaite. Les multiples opérations d'électrodésionisation peuvent avoir lieu dans une seule colonne d'électrodésionisation ou dans de multiples colonnes d'électrodésionisation.

Inventor: MAYNARD ALLISTER J
IPC: C12Q1/68
Filed: 2004-06-14
Abstract: Methods and systems for generating pharmacophore models are characterized both by molecular features that are present in the model and features that are defined as absent. Thus, models can be developed that take into account features such as steric bulk that inhibit activity for a specified target as well as features such as functional groups that promote activity. Features that inhibit activity can be identified by comparing known active molecules with known inactive molecules. Features that are present in the inactive molecules but absent in the active molecules can be defined in a pharmacophore model.

Title: System and method for mixing at least four components
Inventor: DAMM CHRISTIAN
IPC: A61M5/19
Filed: 2004-07-13
Abstract: A system for mixing four components (K1, K2, K3, K4) has a first syringe arrangement (10) and a second syringe arrangement (20). The first and second syringe arrangements (10, 20) each contain at least two chambers (11, 12; 21, 22) for holding one each of the components (K1, K2, K3, K4).

By transferring the components (K1, K2) from one of the syringe arrangements (10) into chambers (21, 22) of the other syringe arrangement (20), the transferred components (K1, K2) are mixed with components (K3, K4) which are contained in this chamber (21, 22).
Patent CA-2474396-A1 (CA)
Inventor: FURCHHEIM BODO
IPC: B21D26/033
Filed: 2002-10-04
Abstract: The invention concerns a method whereby components are arranged in a mounting device, outside an internal high-pressure forming press, in accordance with their position and their function, such that they are linked to one another. The mounting device comprises an upper part and a lower part (1, 2) including cavities identical to the cavities of the internal high pressure tool (4). Once the components have been installed, the mounting device is introduced in the internal high-pressure press, then the upper part or the lower part of the mounting device is withdrawn, the part of the mounting device remaining in the internal high-pressure press being displaced against the upper tool or the lower tool. For the forming process, the components are maintained in a part of the tool by depression or by clamping, then the part of the mounting device is removed from the internal high-pressure press, thereby ensuring high precision positioning of components. Additionally, the production rate is substantially increased. The invention is particularly applicable for the production of camshafts.

Title: Precipitate test for microorganisms
Inventor: MARSHALL ELLIOTT D III
IPC: C12Q1/34
Filed: 1990-04-27
Abstract: An improved method for testing for the presence of a particular microorganism and/or group of microorganisms characterized by a particular enzyme is provided. The method uses a dye-forming and/or fluorogenic-generating substrate throughout a polymer matrix or on the surface of a solid support member that forms a colored precipitate or fluorescent by-product when cleaved by the enzyme. The precipitate is concentrated on the polymer matrix and/or solid support member to create a visible reaction product, Whereas the fluorescent by product will normally be dispersed into the surrounding medium to some extent. The amount of dye-forming substrate needed is independent of the sample size. The present invention further comprises an enzyme indicatordevice comprising a dye-forming and/or fluorogenic-generating substrate throughout a polymer system or on the surface of a solid support member.

Title: High quantum efficiency x-ray detector for portal imaging
Inventor: ROWLANDS JOHN ALAN
IPC: G01N23/04
Filed: 2003-10-07
Abstract: The present invention provides a practical design of a megavoltage x-ray detector with both high quantum efficiency (QE) and high resolution. The x-ray detector disclosed herein has a QE that can be an order of magnitude higher than that of current flat panel systems and yet has a spatial resolution equivalent to that of current flat panel systems used for portal imaging. The x-ray detector includes a large number of micro-structured electrically conducting plates (12), packed together with thin spacers placed between neighboring plates with the micro-structured plates oriented to be parallel to the incident x-rays in operation. Each plate includes an electrically conductive substrate (14, Fig.3) having a planar surface on which are formed elongate electrically conductive strip electrodes (Fig.3, 18) separated from each other with strip spacers (Fig.3, 16) placed in between and sitting on an insulating layer interposed between the first planar surface of the electrically conductive substrate and the strip electrodes. A power supply applies a bias voltage between each electrically conductive substrate and the electrically conductive strip electrodes, whereby x-rays absorbed in the conductive substrate generates high energy electrons which produce ions in an ionization medium located in spaces between the conductive substrate and the electrically conductive strips. A detector detects an electrical current generated in the electrically conductive strip electrodes and a 2D active readout matrix is coupled to the detector.
