Patent CA-2233329-C (CA)
Title: Method for electrolytic deposition of metal coatings
Inventor: DAHMS WOLFGANG
IPC: C25D3/38
Filed: 1996-11-21
Granted: 2005-07-26
Abstract: The invention relates to a process for the electrolytic deposition of metal layers, in particular copper layers, of specific physico- mechanical and optical characteristics and of even thickness. With known processes using dissolving anodes and direct current, only an uneven metal layer distribution can be achieved on articles of complex shape . The problem of uneven layer thickness at different points on article surfaces can be alleviated by using a pulsed current or pulsed voltage process, but this does not solve the other problem of continually changing geometry during deposition as the anodes dissolve. This problem can be eliminated by using non-dissolving anodes. To ensure adequate anode stability and a high lustre of the layers even at points on the workpiece surface where the metal is deposited with high current density, compounds of an electrochemically reversible redox system must be added to the deposition solution.

Inventor: KOBAYASHI TETSUTARO
IPC: G06F7/72
Filed: 1998-11-04
Granted: 2002-06-25
Abstract: The present invention is directed towards a method and system for modular inversion for information security. The modular inversion, including an extended binary GCD, can be determined with a reduced time overhead by the present invention. For determining the modular inversion, digital signals representing values X and N of n-bits and a parameter t are input, then Y is determined where Y is X2-t mod N. Using Y, an extended GCD is used to find S where S is Y-1 2k modN and k and R is determined for S where R is S2-(k+t-2n). A Montgomery inverse of X may be found on a residue class ring Z/NZ using R=X-1 2 2n.

Title: Color display device
Inventor: ARITAKE YASUO
IPC: G09F9/35
Filed: 1998-12-11
Granted: 2006-12-05
Abstract: A color display device has a single light guiding plate, and first, second and third light sources that respectively independently exhibit three primary colors. On a one end surface of the light guiding plate there are disposed the first and second light sources that exhibit two different ones of the three primary colors . On the other end surface side of the light guiding plate there is disposed the third light source that exhibits the remaining one primary color. Since the light guiding means is needed only one in number, the structure can be simplified and miniaturized. Also, on the one end surface of the light guiding means there are disposed, of the three light sources exhibiting the three primary colors, the first and second light sources that exhibit two different ones of the three primary colors. And, on the other end surface side of the light guiding means there is disposed the third light source that exhibits the remaining one primary color. Therefore, the probability that the light which enters into the light guiding means from one light source is hindered by another light source decreases. Accordingly, the loss of the light becomes lessened and the amount of light emission increases.

Title: Mixed gas refrigeration method
Inventor: RADEBAUGH RAY
IPC: F28D7/12
Filed: 1997-08-06
Granted: 2007-04-03
Abstract: A miniatured mixed gas refrigeration system and method of operation are disclosed, having a coaxial catheter (18) with an inner high pressure supply lumen and an outer low pressure return lumen. An optimum gas mixture is formulated from a group of component fluids, according to calculated thermodynamic properties of a group of candidate flu id mixtures. The gas mixture is pressurized by a compressor (12) to a pressure less than 420 psia, for safety reasons. The distal portio n (20) of the outer lumen contains a micro-miniature heat exchanger constructed of laminated plates or sheets. The plates or sheets establish hi gh pressure and low pressure passageways, with high surface area, having a tortuous path for the gas flow to maximize heat exchange. The high pressure outlet of the heat exchanger is connected to a Joule-Thomson expansion element where the high pressure gas is expanded isenthalpically to a lower temperature at least as low as 183K. This low temperature gas cools a heat transfer element mounted in the outer wall of the catheter, to cool an external object. Return gas flows back through the heat exchanger to pre-cool the incoming high pressure gas mixture.

Title: Robust technetium removal method and system
Inventor: GRANT DAVID C
IPC: B01J47/04
Filed: 1998-03-11
Granted: 2007-01-02
Abstract: The invention provides a method and processing system (10) for removing both anionic and cationic technetium complexes from an aqueous solution by adjusting the pH of the solution to greater than approximately 2, and directing the solution into an integrated resin and electrochemical plating device (30). The integrated resin and plating device (30) has a resin bed (32) or resin membrane in which is disposed one or more cathodes (38), and one or more anodes (36). A potential generator (34) produces at least a 1 volt potential between the cathodes (38) and anodes (36). As the solution passes through the resin (32), the technetium complexes are absorbed onto it. When a sufficient concentration of technetium complexes is adsorbed, the plating process can alternatively be driven to plate out the technetium onto the cathodes, or to collect various species in system anolytes/catholytes.

Title: Method and apparatus for detecting modified color burst signals to prevent the copying of a video program
Inventor: RYAN JOHN O
IPC: H04N5/91
Filed: 1998-03-20
Granted: 2002-12-10
Abstract: A video signal is modified so that a television receiver will provide a norm al color picture but a video tape recorder will detect the modification and prohibit the video signal from being recorded. The color burst phase of the video signal is modified so as to make inferior quality pictures in the even t that the resulting modified video signal is recorded. A disabling circuit (2 2) associated with the recorder (20) detects the presence of the modified video  signal. This detection is done by determining the presence of modified color  burst phase signals in even a single television line of the video signal. A control signal (26) is produced when the modified color burst phase signal i s detected, which disables the recorder (20). If no modified color burst phase  signal is detected, the recorder (20) is enabled to allow an acceptable recording of the video signal.

Abstract: A stentless aortic bioprosthesis having patent, non-ligated coronary artery segments extending therefrom, and methods for surgical replacement of aortic and/or non-aortic (e.g., pulmonary) heart valves with such stentless aortic bioprosthesis. The presence of the patent, non-ligated coronary segments facilitates end to end anastomosis of the patient's native coronary arteries and/or existing coronary artery bypass grafts to the coronary segments of the bioprosthesis even when such native coronary arteries (or coronary grafts) arc too short to reach the wall of the aortic segment of the bioprosthesis. The presence of such patent, non-ligated coronary segments also eliminates the need for removal of a "button" or segment of the native aorta in connection with the native coronary artery segments prior to implantation of the bioprosthesis, and is thus advantageous for patient's whose ascending aorta is diseased or otherwise compromised.
