Title: Heat exchanger
Inventor: AKIMOTO RYOUSAKU
IPC: F25B39/00
Filed: 2000-05-30
Abstract: A heat exchanger is used for an air conditioner installed in a vehicle such as an electric car and is basically designed as a laminated type, which is constructed by assembling a pair of heat-exchanger units (A, B) together.   Herein, each of the heat-exchanger units is constructed by a pair of headers (10, 11), which are arranged in parallel with each other in a vertical direction and between which tubes (12) and cooling fins (13) are alternately arranged along a horizontal direction. Herein, each of the tubes and each of the cooling fins are extended in the vertical direction between the headers. Partition plates (16) are arranged inside of the headers at selected positions such that an overall front area in which the tubes and cooling fins are alternately arranged between the headers is divided into a number of parts (PA, PB), among which refrigerant sequentially flow from one part to another in a reciprocating manner. Herein, all the parts can be equally divided to have a same sectional area, or they are gradually changed (i.e., reduced or enlarged) in sectional area along a refrigerant flow direction corresponding to the horizontal direction. It is possible to change an overall front shape of the heat exchanger, which is originally a rectangular shape, to a prescribed shape such as an L-shape using an intermediate header (17), by which the heat exchanger is arranged not to interfere with some device or equipment inside of the vehicle.

Patent CA-2322141-A1 (CA)
Inventor: KARL CLIFFORD W
IPC: G01N35/00
Filed: 1997-02-12
Abstract: An automatic sample testing machine for testing samples stored in test cards.  The machine has a test sample positioning system for moving a tray containing a plurality of test sample cards and fluid receptacles among various stations in the machine. The machine has a diluting station for adding a predetermined quantity of diluent to the receptacles as needed. A pipetting station transfers fluid from one receptacle to another. A  vacuum station is provided having a vacuum chamber moveable relative to the tray between upper and lower positions. The chamber cooperates with the tray to make a sealing engagement with the top surface of the tray when it is lowered to the lower position. A vacuum generator supplies vacuum to the chamber. When the vacuum is released from the chamber, the fluid samples are loaded into the cards from the receptacles. The test sample positioning system moves the tray to a cutting and sealing station and then to an incubation station and loads the cards one at a time into a carousel within the incubation station. A test card transport station transports the test cards from the incubation station to an optical reading station, where optical measurements (e.g., transmittance and/or fluorescence optical testing) is conducted on the wells of the card. When the card has been read, it is either moved back to the incubation station for additional incubation and reading or transferred to a stacking card disposal system when the reading is complete.

Title: System and method for arithmetic operations for electronic package inspection
Inventor: KING STEVEN JOSEPH
IPC: G06V10/147
Filed: 1999-08-09
Abstract: An inspection system and method uses a first illumination apparatus to illuminate one or more features. Once the object being inspected is illuminated, a first reflected image of the features is captured by an illumination detection device (420). The image is then stored (430). The object being inspected is then illuminated by at least one additional illumination apparatus (440). Each additional illumination apparatus is selected so that it differs from other illumination apparatuses in either geometrical arrangement, degree of diffusion or illumination characteristic.  An additional reflected image is then captured by each additional illuminati on apparatus (450). Each additional reflected image is then stored (460). Once at least two reflected images are captured and stored, they are combined by an image processor using at least one arithmetic operation to create a resultin g image in which at least one selected feature is enhanced (470). The enhanced  features appearing on the resulting image can then be inspected using additional image processing equipment using standard image analysis techniqu es.

Abstract: Cette invention se rapporte à des séquences d'ADN synthétiques modifiées, permettant une meilleure action insecticide, en raison de la plus grande maturation de l'ARNm, de leur stabilité et de leur translation accrue dans les plantes supérieures. Ces séquences d'ADN synthétiques sont des outils utiles pour gérer la résistance, en particulier pour surmonter les problèmes de résistance croisée. On obtient des améliorations en effectuant des modifications synthétiques de la séquence d'ADN tronquée (numéro d'identification de séquence 3) du gène cry9Aa, de préférence du numéro d'identification de séquence 2 codant pour une protéine se caractérisant par une séquence d'acides aminées de numéro d'identification de séquence 1, ou pour des altérations de celle-ci, produisant pour ainsi dire la même action insecticide que la protéine insecticide codée par le gène cry9Aa du Bacillus thuringiensis ssp. gallieria (Btg). Cette invention concerne également l'utilisation de ces séquences d'ADN synthétiques modifiées pour produire une telle protéine insecticide et pour produire des plantes transgéniques exprimant des quantités efficaces de ces protéines insecticides.

IPC: A61K31/47
Filed: 1999-10-12
Abstract: Receptor blocker (antagonist) drugs which suppress the binding of the D4 class of leukotriene molecules to leukotriene receptors can reduce the frequency and severity of recurrent primary headaches, including migraine and cluster headaches. Various LTD4 receptor blockers are commercially available, including montelukast and zafirlukast. In the past, these drugs have been used to treat asthma. During human clinical trials on asthma patients, headaches were one of the most commonly reported side effects of each of those two drugs; therefore, they apparently were never tested as agents which might prevent or reduce migraine or cluster headaches. However, it has been shown that in at least some patients who suffer from acute recurrent migraines, LTD4 receptor blockers can greatly reduce the frequency, duration, and/or severity of their headaches, when taken chronically on a daily basis. Tests also indicate that LTD4 receptor blockers can effectively treat onset of acute migraine or cluster headaches, and can also be combined with a triptan drug to achieve a synergistic effect against acute headaches.
