Patent CA-2064423-A1 (CA)
Title: Differential-free space optical signal transmission
Inventor: HUANG ALAN
IPC: H04B10/118
Filed: 1992-03-30
Abstract: DIFFERENTIAL FREE SPACE OPTICAL SIGNAL TRANSMISSION Abstract Alignment problems are mitigated in connection with optical signal transmission and similar multiple path-supporting transmission media by the use of differential optical transmission. When the source signals are electronic, a complementary signal is developed electronically, and the signal and its complement are each applied to a light emitting device. The light of each of the light emitting devices is collimated with a lens and transmitted to a receiving lens. The two receiving lenses focus their respective collimated input onto photodetectors which convert the light to electronic signals, and the electronic signals of the two photodetectors are applied to a differential amplifier. The two lenses that transmit the signal and its complement for a transmitting pair, and the two lenses that receive the signal and its complement form a receiving pair. To utilize the advantages of this invention, the transmitting pair and the receiving pair need to be aligned with respect to each other so that each of the photodetectors receives approximately the same proportion of the transmitted optical signal of the two light emitting devices, respectively.

Title: Cup-type harmonic drive having a short, flexible cup member
Inventor: KIYOSAWA YOSHIHIDE
IPC: F16H49/00
Filed: 1992-05-20
Abstract: A cup-type harmonic gear drive comprises a rigid circular spline, a cup-shaped flexspline disposed inside the circular spline and a wave generator means fitted inside the flexspline for flexing the flexspline into elliptic to engage it with the circular spline and for rotating the engagement portions to thereby produce relative rotation between the splines. The flexspline has a tube, a disc-shaped diaphragm connected integrally to the end of said tube to define the cup bottom, and a thick boss formed on the center of the diaphragm. The diaphragm has a root portion from the boss, a thickness of which is set at least about three times the minimum thickness of the diaphragm. The outer profile of the diaphragm is defined, when viewed along a plane including the axis of the flexspline, by a plurality of curves having a different curvature.      These curves are arranged from one having a larger curvature from the root protion to the tube portion of the diaphragm. Thus, the stress distribution of the flexspline can be made smooth to the extent for practical use even where a shorter flexspline is adopted.

Abstract: Disclosed is a slider with an air bearing surface for flying a magnetic transducer on an air  lubrication film over a moving recording medium.  The air bearing surface allows the slider to fly at a close and substantially uniform height over the disk surface regardless of the skew angle of the air flow.   The  slider  has  a  pair  of  nonidentical, nonsymmetrical rails disposed about the longitudinal axis of the slider,  which through the viscous effects of the air flow, provide the air lubrication film when the recording medium is in motion.

Patent CA-2075050-A1 (CA)
Inventor: BLOCH WILL
IPC: C08J7/046
Filed: 1991-02-15
Abstract: Improvements to the polymerase chain reaction (PCR), a process for in vitro enzymatic amplification of specific nucleic acid sequences, can be achieved by changing the way that PCR reagents are mixed and the enzymatic reaction is started and by the replacement of mineral oil, commonly used as a vapor barrier to minimize solvent evaporation, by a grease or wax. The use of such mixtures allows for the delay of reagent mixing until the first heating step of a PCR amplification, thereby reducing the enzymatic generation of nonspecific products which occurs when a complete mixture of PCR reagents, with or without test sample, stands at room temperature or below. These mixtures increase the shelf-life of PCR reagents and increase protection of the laboratory environment against contamination by PCR product.

Ce fléau social fait actuellement la manchette et est un sujet de préoccupation nationale puisque nos dirigeants gouvernementaux déclarent eux-mêmes et ce, ouvertement, leur absence de contrôle de la situation et ne peuvent prédire jusqu'où la situation va dégénérer. Il s'agit d'un problème national sérieux et il convient d'y trouver une solution rapidement.

Patent CA-2092537-A1 (CA)
Title: Inhibition of restenosis of ultraviolet radiation
Inventor: CLARKE RICHARD H
IPC: A61N5/06
Filed: 1991-09-04
Abstract: Restenosis following angioplasty can be inhibited by reducing the proliferation of smooth muscle cells in the blood vessel walls at an angioplasty site, and such reduction in cell proliferation can be accomplished by an apparatus which irradiates the angioplasty site with radiation in the ultraviolet (UV) wavelength range.  The ultraviolet radiation is preferably delivered via an optical fiber or other waveguide incorporated, for example, into a percutaneous catheter. In operation, the ultraviolet radiation kills smooth muscle cells at the site, thereby reducing the risk of restenosis, while minimizing damage to surrounding tissue.

Title: Curved sanitary napkin with upstanding fluid barrier walls
Inventor: MCDANIEL MARY L
IPC: A61F13/15
Filed: 1993-04-19
Abstract: ABSTRACT OF THE DISCLOSURE   A curved sanitary napkin is disclosed which has a pair of longitudinally extending, upstanding fluid barrier walls.  The sanitary napkin includes an absorbent having a body-facing surface, a garment-facing surface and a pair of longitudinally extending sides. The sides being closest to each other approximate a central portion of the absorbent.  A liquid-impermeable baffle is positioned adjacent to at least the garment-facing surface of the absorbent and a liquid-permeable cover cooperates with the baffle to enclose the absorbent. The cover has an upper surface with a pair of spaced apart longitudinal folds integrally formed on the upper surface.  Each of the folds has an inside surface to which is affixed an elastic member.  The elastic enable the folds to form upstanding walls which extend the entire length of the sanitary napkin.  The upstanding walls are aligned vertically above the longitudinal sides of the absorbent for preventing side leakage of body fluid.  In addition, the elastic members cause the sanitary napkin to acquire a cup-shaped configuration with the central portion forming the deepest portion of the cup.  The central portion corresponds to the perineal area of the user.

Title: Thin offset drawer slide with progression roller
Inventor: KOVARIK FRANZ
IPC: A47B88/04
Filed: 1993-06-04
Abstract: A thin profile drawer slide apparatus for slidably supporting a heavy drawer in furniture, comprising symmetrical, identical channel members for slidably attaching the apparatus to a drawer and an article of furniture, a plurality of bearings slidably retained in the channel members by bearing retainers, and by an intermediate slide member. The intermediate slide member comprises the unitarily formed combination of a generally vertical central wall, a first bearing raceway joined to an end of the central wall, and a second bearing raceway joined to an arcuate wall extending angularly outwardly from the first bearing raceway, whereby the first and second bearing raceways are vertically and angularly separated. The ball bearings are arranged in four linear, slightly offset sets. Use of a single intermediate slide member with raceways for four separate sets of bearings provides a thin, strong drawer slide for carrying heavy loads. The central wall of the intermediate slide member comprises a generally rectangular window with a progression roller mounted therein on a vertical axis of rotation. The roller exerts friction on the inner faces of the channel members by compression against the inner faces when the roller is moved. Each channel member comprises at least one roller clearance window. Edges of window act as a detent on the roller and also urge the slide closed when the slide is brought to rest with the roller against one of the edges. The windows relieve compression of the roller when the slide is fully closed.
