Abstract: This invention relates to an improved method of depositing cobalt silicide films on a substrate by chemical vapor deposition at a temperature range of about 100.degree.-400.degree. C. By employing two separate precursors of, preferably, for cobalt, comprised of cobalt carbonyls having a vapor pressure sufficiently high to provide a cobalt stream to support chemical vapor deposition, and for silicon, comprised of silanes or halogenated silanes having a vapor pressure sufficient to support chemical vapor deposition, a cobalt silicide film is grown. The ratio of silicon to cobalt is controlled precisely by varying the substrate temperature while the process is being conducted. In a more specific aspect, the films are grown on substrates of either gallium arsenide or silicon. In the case of silicon, epitaxial growth of the cobalt silicide film is achieved by specific control of process parameters.

Abstract: The invention relates to a sensor system for in-situ monitoring of lubricant oil quality. The sensor system consists of a sensing element located in-situ in contact with lubricant oil. The sensor is corrodable and upon deterioration of the oil the sensor corrodes and eventually the circuit will break. Current flow through the circuit is monitored by conventional power supply and measuring devices and upon breaking of the sensor, an indication is provided to the driver of a motor vehicle indicating that oil is to be changed.

Abstract: A medical laser provides to a biological target both a laser wavelength in the deep red-near infrared region of the spectrum and a wavelength in the blue-near ultraviolet region. The short wavelength blue light cuts the target tissue, while the longer-wavelength red light cauterizes. The long-wavelength radiation may be provided by an alexandrite laser, with a harmonic generator providing half the fundamental wavelength. Alternatively, the short-wavelength radiation may be provided by an alexandrite laser, with a harmonic generator providing half the fundamental wavelength. Alternatively, the short-wavelength radiation may be provided by a xenon fluoride laser, with a Raman cell shifting the radiation from the ultraviolet into the visible. Generally, at least one of the wavelengths is visible on the target and both wavelengths may readily be transmitted by conventional optical fibers.

Abstract: The invention relates to an improved sensor for use in-situ in an electrical circuit which sensor corrodes as a result of deterioration of the oil and provides a changing electrical current due to increased resistance resulting from said corrosion. The sensor preferably is a ceramic tube havign a first layer of electrolessly deposited nickel thereon with a second layer of electrolitically plated lead. Leads are attached to the ends of the tube and the sensor can then be employed in-situ in oil to, as a result of its corroding and change in resistivity, measure deteriorating oil quality.

Abstract: A simple, compact, and rugged laser comprises a solid transparent housing with two cavities. A laser medium is embedded in one cavity and a pump lamp in the other. By choosing for the housing and lamp envelope materials having thermal expansion coefficient similar to that of the laser medium, high power operation is feasible. An optional reflecting coating on the exterior of the housing enhances efficiency. An optional filter coating on the lamp envelope eliminates unwanted components of lamp radiation.

Abstract: A magneto-optical element comprises a magnetic garnet layer on a crystalline substrate. The garnet layer has a faceted structure, which provides high Faraday rotation and controlled coercivity. The faceted structure is preferably formed by depositing the layer onto a substrate whose lattice constant is sufficiently smaller than that of the layer. The resulting elements find application in light modulators, such as switches and displays, where they permit high resolution without having to be cut into an array of small cells.

Abstract: A multi-layer luminescent screen includes a luminescent crystalline sublayer and a faceted overlayer. The faceted overlayer causes the emission from the screen of a greater fraction of the luminescence than would otherwise be the case. The screens, which are typically cathodoluminescent, find application in computer displays, lithography, and flying spot scanners.

Abstract: A partially-transparent, noble-metal protective overcoat is provided to a front-surface silver reflector. The overcoat, preferably of gold, may be applied by vacuum-deposition or electrodeposition. Optimum overcoat thickness is the minimum required to protect the reflector in the environment of its intended use. The overcoated reflector of this invention is particularly well suited for the surface of a laser pump cavity.

Abstract: A single crystal of rare-earth-doped lanthanum beryllate, whose crystal orientation is suitably chosen, provides a laser medium whose index of refraction is substantially independent of temperature. A laser using such a crystal as the laser medium displays little or no thermal lensing, thus permitting high power operation without wavefront distortion.

Abstract: An apparatus is provided for the exposure of a recording carrier including alpha numeric characters or faces having a foreground pattern contrasting relative to a background pattern. In accordance with the apparatus, the alpha numeric characters or faces in front of a background pattern are exposed by an intensity modulated scanning beam along scanning lines on the recording carrier. At the character or face borders, a switch-over control logic (3) switches over a modulator switch (2) connected to a scanning beam modulator (1) on various signal sources. The signal sources comprise raster video signal sources (10). A plurality of signal sources, which at the same time are prepared, in parallel relative to each other, to generate foreground pattern signals and background pattern signals, are controlled by a preselection control logic (13) which may be adjusted to maintain a preselection control state over arbitrarily selectable scanning line sections.

Abstract: The invention relates to an improvement in a method for the synchronization of a material web, particularly a photosensitive material web in a photo typesetting process. Typically, an optical path is transverse to the direction of motion of a material web normally transportable with an approximately constant transport speed. The web is deflected into deflection lines, and if necessary scanned, to have images exposed. The transport speed and the deflection speed are controllable by common clock pulses. At the beginning of each deflection line, a reference signal (SOL) for time and deflection position is generated. In order to retain, in case of an interruption of the scanning, the regular scanning structure of the scanning on the material web, the following steps are provided as an improvement. In case of an interruption of the scanning, reference signals are generated while line-wise deflection of the optical path is continued.

Abstract: A fiber optic connector, especially for multiple-core fiber optic cables, in which a ferrule (2), mounted in a ferrule insert (3), and adapted to receive the optical fiber (P), is provided in a plug (A,B). An adaptor (C) is provided for receiving the plug, and includes a holding sleeve (11) which is retained in an insert (10). A split sleeve (12) is mounted in the holding sleeve (11) for receiving the ferrule (2). A terminal part (11b) of the holding sleeve protrudes from the surface of the insert (10) and is snugly received in an insertion recess (14) provided at the forward end of the ferrule insert (10). The terminal part (11b) enters recess (14) after the ferrule (2) has entered the split sleeve (12) at the time of connection of the plug and adaptor.

Abstract: A fiber optic cable connector is disclosed which will prevent the filament from being dislocated from the polished front contacting surface of the connector although the filament tends to move relative to the cable jacket in lengthwise direction of the cable under temperature change or bending influences. The cable jacket is fastened in a rear part of the connector housing, and the filament is fastened to a front part of the connector housing. The fastening zones of the cable jacket and the filament are held in fixed spaced relationship in lengthwise direction of the cable, and a compensating space is defined therebetween for receiving a portion of the filament with substantial looseness or freedom of lateral movement.

Abstract: A system and apparatus for containing and dispensing medications in a prescribed manner, and for reducing the possibility of incorrect dosages being taken and/or medication being taken at the wrong time of the day. A tray contains plural rows and columns of cavities, and each cavity is adapted to contain medication therein. The cavities include structure dividing them into two parts. A first part is open to the user to enable the user to place medication therein and to remove medication therefrom. A second part is closed off from direct access by the user in semi-permanent fashion by a transparent enclosure and is used to contain in a preferred embodiment, an exemplification of a appropriate dosage of medication to be taken. For example, if five green pills are to be taken, the enclosed portion will contain five green pills viewable through the transparent enclosure. The dose example of medication contained therein is the dose amount and type medication to be placed in each open cavity structure each day.

Abstract: An optical flat bed deflection system comprises at least one rotating active reflective face (6) for deflecting a beam of parallel rays (1) along a deflection or scan line in a planar deflection plane (15), and an imaging optical system, i.e., an f.theta. lens arrangement, interposed between the active reflective face and the deflection plane. In order to reduce the disturbing influence of the bearing wobbling during rotation, on the image, a reverse-telescope like optical system is provided in front of the imaging optical system for enlarging one exit angle of the active reflective faces. In connection therewith, only two rotating active reflective faces are provided, each one of which is provided as a prism.

Abstract: A fiber optic connector includes a connector assembly for connecting a fiber optic cable thereto. The connector assembly includes an arrangement whereby the cable can be crimped and attached to the connector without crimping force being exerted on the buffer layer of the cable. The connecting end of the connector has the capillary ferrule extending outwardly therefrom in a spring loaded manner. In connection with another connector the respective ferrules are held in a centering sleeve and retract against the compressive force of a spring into each connector thereof to ensure alignment and tight connection between the core elements held by the ferrules. In order to permit repeat connections, the ferrules are held non-rotatively within the connectors.
