Patent CA-2083121-A1 (CA)
Inventor: CHO ALFRED Y
IPC: H01L33/40
Filed: 1992-11-17
Abstract: This invention embodies a LED in which an optical cavity of the LED, which includes an active layer (or region) and confining layers, is within a resonant Fabry-Perot cavity. The LED with the resonant cavity, hereinafter called Resonant Cavity LED or RCLED, has a higher spectral purity and higher light emission intensity relative to conventional LEDs. The Fabry-Perot cavity is formed by a highly reflective multilayer distributed Bragg reflector (DBR) mirror (RB ~ 0.99) and a mirror with a low to moderate reflectivity (RT ~ 0.25-0.99). The DBR mirror, placed in the RCLED structure between the substrate and the confining bottom layer, is used as a bottom mirror. Presence of the less reflective top mirror above the active region leads to an unexpected improvement in directional light emission characteristics. The use of a Fabry-Perot resonant cavity formed by these two mirrors results in optical spontaneous light emission from the active region, which is restricted to the modes of the cavity. While the bottom DBR mirror reduces absorption by the substrate of that light portion which is emitted toward the substrate, the two mirrors of the resonant cavity reduce the isotropic emission and improve the light emission characteristics in terms of a more directed (anisotropic) emission.

Inventor: EDELEN STEPHEN A
IPC: F16H61/28
Filed: 1992-12-03
Abstract: A position-feedback-control servomechanism for shifting the transmission (10) of a vehicle has a control algorithm that adjusts the loop gains (148, 156) in a proportional-integral-differential controller to compensate for manufacturing variations in the apparatus as well as for temperature changes and wear.          The resulting control system moves the shifting servomechanism (26) into the selected positions accurately and as quickly as possible without permitting excessive overshooting (71) or resonance.

Title: Antithrombosis agents
Inventor: WOLF DAVID
IPC: C07K14/745
Filed: 1991-09-04
Abstract: Analogs of Factor Xa (Factor Xai) which are inactive as proteases in the prothrombinase reaction are useful in treatment of diseases characterized by thrombosis. These antithrombotic agents can be conveniently prepared using recombinant techniques. In addition, modified forms of Factor Xa that generate Factor Xa in serum but have extended half-lives are useful in treating hemophilic conditions. These modified forms of Factor Xa are typically acylated forms of the serine residue in the active site which are slowly deacylated in vivo.

Patent CA-2099522-A1 (CA)
Inventor: BARRETT CHARLES D JR
IPC: F16H1/06
Filed: 1993-07-02
Abstract: A lubricator for large diameter open gearing or other fluid dispensing system utilizes a header having a series of orifices which direct streams of oil onto a deflector plate which produces a spray directed at the teeth of a drive pinion in close proximity to the point of first engagement on the approach side of the pitch point.  Air turbulence generated by movement of the gear teeth is prevented from affecting the spray pattern by utilizing a collector for excess lubricant as a baffle and by utilizing the deflector plate to block the movement of air.  Uniformity of spray pattern from the orifices is enhanced by providing a pressure relief valve remote from the feed points of the header.

Title: Process and a device for the continuous nondestructive control of rails on a railway line by ultrasonics
Inventor: JAEGGI JEAN-PIERRE
IPC: G01N29/06
Filed: 1993-12-21
Abstract: ABSTRACT   The continuous nondestructive process for controlling the rails on a railway line by ultrasounds is novel in that the emission of ultrasounds takes place successively at different points along the rail which are spa-ced apart by a measured value. For each echo, the acoustic distance bet-ween the point of emission and the point of reflexion of the beam of ul-trasounds is determined, and then a bidirectional map of the echoes is established by correlation. Finally, this echo map is compared to a mask having a window, of which the shape, the orientation and the dimensions are determined by the characteristic features of the rail to be examined and by the type of defect looked for, only those echoes which appear in this window being then taken into consideration.
