Patent CA-2475000-A1 (CA)
Inventor: TANIDA MUTSUMI
IPC: B32B15/04
Filed: 2003-02-05
Abstract: Martensitic stainless steel whose steel composition is restricted within a specific range for each element is provided. The scale layer formed on the surface of the base material consists of an inner layer scale mainly including FeCr2O4 and an outer layer scale having a thickness of not more than 20 ~m, which outer layer is deposited on the inner layer scale at a surface coverage of not less than 1% and not more than 15%. The application of rust preventive oil onto the surface of the steel ensures an excellent weather resistance during a long term, and therefore a martensitic stainless steel forming no rust either in the outdoor depository or in the indoor depository can be provided. The steel can be used to manufacture, not only steel pipes, but also steel plates, steel rods and others in a wide application field.

Inventor: MACGLINCHY TIMOTHY BRYAN
IPC: E06B3/673
Filed: 2003-06-26
Abstract: A method and apparatus for heating and/or pressing sealant of an insulating glass unit. The apparatus may include an oven and a press. The oven includes a detector that detects an optical property of the insulating glass unit. The detected optical property is used to regulate the amount of energy applied to the insulating glass unit to adjust the amount of energy applied to the sealant.

Patent CA-2481239-A1 (CA)
Inventor: JETTE CICELY A
IPC: C12Q1/68
Filed: 2003-04-07
Abstract: L'invention concerne de nouveaux procédés de détection de composés pour traiter le cancer du colon. A l'aide d'une technique de profilage d'expression de microréseaux, on a mis en évidence, sur le plan moléculaire, que l'absence de différentiation constituait le mécanisme de développement des polypes du colon et des tumeurs. Une absence de gènes de réponse à l'acide rétinoïque des tissus du colon néoplastques a été observée. On a établi un parallèle entre l'absence de ces gènes et le manque d'expression de la rétinol déshydrogénase 5 et d'un nouvel homologue de la rétinol déshydrogénase, RDHL. L'expression de RDHL est essentiellement restreinte au colon normal, et les facteurs de transcription spécifiques au colon, cdx1 et cdx2 peuvent réguler RDHL. En outre, une nouvelle introduction du gène APC se traduit par une nouvelle expression de RDHL.

Title: Improved fuel cell
Inventor: SAITO YUJI
IPC: H01M8/00
Filed: 2003-05-09
Abstract: A simple, inexpensive and highly efficient fuel cell has boundary structures made of a photo-sensitive material in combination with selective patterning.  Printed circuit board (PCB) fabrication techniques combine boundary structures with two and three dimensional electrical flow path. Photo-sensitive material and PCB fabrication techniques are alternately or combined utilized for making micro-channel structures or micro stitch structures for substantially reducing dead zones of the diffusion layer while keeping fluid flow resistance to a minimum. The fuel cell assembly is free of mechanical clamping elements.  Adhesives that may be conductively contaminated and/or fiber-reinforced provide mechanical and eventual electrical connections, and sealing within the assembly. Mechanically supporting backing layers are pre-fabricated with a natural bend defined in combination with the backing layers' elasticity to eliminate massive support plates and assist the adhesive bonding. Proton insulation between adjacent and electrically linked in-plane cell elements is provided by structural insulation within the central membrane.

Patent CA-2497036-A1 (CA)
Title: Surgical needle manufacturing process
Inventor: BOGART MICHAEL
IPC: B21G1/00
Filed: 2005-02-15
Abstract: A process for manufacturing a surgical needle incorporates at least one pressing operation which, preferably, in conjunction with a trimming and/or etching process, ultimately forms the sharpened needle end. The grinding operation in the preferred process does not produce the primary sharpened edges of the needle, but, rather is incorporated, in one instance, to reduce excess needle material prior to the pressing operation. Consequently, the amount of flash material generated during pressing is substantially reduced. This feature desirably enhances the subsequent trimming and etching operations, and produces a needle which is extremely sharp, durable and exhibits an improved retention of sharpness over periods of prolonged use.
