Title: Fiber optic end connector
Inventor: SZEGDA ANDREW
IPC: G02B6/36
Filed: 1992-07-22
Abstract: ABSTRACT OF THE DISCLOSURE       An end connector for connecting a tubular support structure having at least one optic fiber associated with a fiber optic cable, to a terminal of an associated device. A housing member is configured with a passageway from a front end to a rear end for passing the tubular support structure therethrough.  A clamping portion including a flexible sleeve and compression grommet are received and supported by both the housing and a compression nut which couples to the rear end of the housing. As the compression nut is threaded onto the rear end of the housing, the compression grommet is compressed, and in turn the flexible sleeve constricts to apply clamping pressure to the tubular support structure holding the optic fibers.

Patent CA-2085117-A1 (CA)
Title: Power amplifier
Inventor: BLACK GREGORY R
IPC: H03G3/20
Filed: 1992-04-08
Abstract: An amplifier which contains two amplifier stages. Each amplifier stage (433,435) utilizes a diode (407) to attenuate the RF input signal (401) and to stabilize the bias current over temperature.  The two amplifier stages (433, 435) are cascaded together.  The control voltage inputs are serially coupled through a transistor (423). The transistor (423) shifts the voltage of the control signal (425) down, thereby, shifting the control characteristics and AM characteristics of the first amplifier stage (435) relative to the second amplifier stage (433).

Patent CA-2087356-A1 (CA)
Inventor: BERGER PAUL R
IPC: H01L31/10
Filed: 1993-01-15
Abstract: This invention pertains to a p-i-n In0.53 Ga0.47 As photodiode having an optically transparent composite top electrode consisting of a thin semitransparent metal layer from 10 to 40 nm thick and a transparent cadmium tin oxide (CTO) layer from 90 to 600 nm thick. The metal layer makes a non-alloyed ohmic contact to the semiconductor surface, acts as a barrier between the semiconductor and the CTO preventing oxidation of the semiconductor from the O2 in the plasma during reactive magnetron sputtering of the CTO layer, and prevents formation of a p-n junction between the semiconductor and CTO. The CTO functions as the n or p contact, an optical window and an anti-reflection coating. The top electrode also avoids shadowing of the active layer by the top electrode, thus allowing greater collection of incident light. Since the top electrode is non-alloyed, inter diffusion into the i-region is not relevant, which avoids an increased dark current.

Title: Method of making robust fiber optic coupler
Inventor: MILLER WILLIAM J
IPC: G02B6/287
Filed: 1993-09-29
Abstract: Abstract Of The Disclosure After a plurality of optical fibers are fused to make a fiber optic coupler, the ends thereof are glued to a substrate to provide the outwardly extending fibers with adequate pull strength.  The glue can flow from the point of application toward the fused region where it can adversely affect the the device.  To prevent the glue from flowing too far toward the fused region and yet permit sufficient flow to strengthen the fibers, a beam of UV light is directed onto the fibers at that predetermined point where glue flow should stop.  When the glue is cured by the beam, it stops flowing.  Thereafter, the remainder of the glue is cured.

IPC: E21B/
Filed: 1992-04-24
Abstract: A machine for performing work at great depths utilizes the energy which is released when surrounding water masses at great hydrostatic pressure are admitted into a low pressure reservoir via a hydraulic motor (2). The machine uses a built-in low pressure reservoir (3) as a hydrostatic accumulator, the energy which is released when the surrounding fluid is admitted into the low pressure reservoir being determined by the product of the pressure difference and the internal volume of the low pressure reservoir. In a special version (Fig. 10) the machine is designed as a hydrostatic sampler which is particularly adapted for taking core samples or marine sediments on the seabed.

This key maybe changed from time to time to increase security. To facilitate authentication the corresponding decryption key is encrypted with another key and incorporated on the card. To validate the card the coded message is scanned, decoded, decrypted, expanded and displayed.  The card may then be authenticated by comparison of the displayed representation of the image and the displayed text message with the image and text message printed on the card.
