Patent WO-8401240-A1 (WO)
Inventor: GATES JAMES L
IPC: H01L23/48
Filed: 1983-09-08
Abstract: Procédé et structure permettant de réduire la surface spécifique occupée par une traversée dans un substrat semiconducteur. Un chemin conducteur horizontal noyé (30) est disposé sur une surface principale (12) du substrat (10), une extrémité (32) du chemin conducteur (30) étant en contact électrique et physique avec la traversée (20) (par exemple le résultat d'une fusion en zones à radient thermique TGZM). Une couche épitaxiale (40) est déposée sur le TGZM et sur le chemin conducteur horizontal noyé (30). On effectue un contact électrique sur l'extrémité distale (31) du chemin conducteur horizontal noyé (30) par diffusion au travers de la couche épitaxiale (40) qu'on vient de déposer ou par gravure du chemin conducteur. La région diffusée (50) présente les mêmes caractéristiques de dopant et le même type de conductivité que le chemin horizontal (30) et le TGZM. La zone de section transversale de la région de la diffusion (50) mesure entre 25 et 30 microns carrés comparée à la zone mesurant entre 507 et 2027 microns carrés du TGZM. Cela se traduit par une réduction considérable de la surface spécifique occupée par les structures de traversée et permet de réaliser davantage de dispositifs sur la surface du substrat.

Title: Method and apparatus for calibrating a surface scanner
Inventor: GALBRAITH LEE K
IPC: H01L21/66
Filed: 1984-01-30
Abstract: A test device for calibrating an optical scanner wherein microscopic patterns (21) of light scattering elements (13, 15) simulate the scattering of light from particles or flaws of different sizes. Simulation of different particles sizes is achieved by means of clusters (25, 29, 33, 37) or arrays of these light scattering elements having different areawise densities. Patterns of such clusters or arrays are disposed on a surface with intervening spaces (17) where a random assortment of foreign particles may be expected. In this manner, the foreign particles may be directly compared to a test pattern. The test surface may be a semiconductor wafer (41) having a thin, inert coating with openings (45) therein forming the light scattering elements. The openings may be made by photolithographic techniques, i.e., masking and etching, so that various patterns on a surface may be all created simultaneously by the same process.
Patent WO-8404878-A1 (WO)
Title: Digitally controlled x-ray beam attenuation method and apparatus
Inventor: MISTRETTA CHARLES A
IPC: H05G1/26
Filed: 1984-05-31
Abstract: X-ray compensation masks (51) are prepared by exposing an X-ray target object (43), such as a patient, to a first beam of X-rays. The X-ray fluence from the patient is received by an electronic image receptor (44) which provides an output signal indicating the intensity of the X-rays at all positions in the image field. The image information is converted by an image processor (47) to transformed X-ray intensity values for a plurality of pixels which cover the image field. A mask generating controller (48) determines the minimum transformed intensity value for any pixel, assigns to each pixel an attenuation number which is proportional to the difference between the transformed intensity value for the pixel and the minimum transformed intensity value, and issues control signals to a mask former (49) which deposits on a non-attenuating substrate (50) attenuating masses in a two dimensional array of pixels with the mass thickness in each pixel proportional to the attenuation number. When the mask (51) is inserted into the beam from the X-ray source (41), and a second exposure taken, the X-ray fluence passing through both the attenuating mask (51) and the patient (43) will be substantially equalized across the image field.

Title: Electronic sound detecting unit for locating missing articles
Inventor: BAYER EDWARD B
IPC: G08B1/08
Filed: 1984-06-29
Abstract: A miniature, battery-powered electronic unit adapted to be attached to a common article such as keys or eyeglasses. The unit is responsive to a plurality of sounds for emitting audible tones to enable a misplaced article to be located. A sound detecting and indicating circuit provides the audible tones upon receipt of a sequence of sounds falling within predetermined frequency, time spacing and amplitude ranges. The correct sequence of sounds is generated by the user by clapping, whistling or making any other loud sounds, and no additional transmitting device is required. Improper sequences of sounds are prevented from producing false activation of the unit. Extremely low power consumption, resulting in part from CMOS technology, allows the unit to remain on continuously for a period of six to nine months using standard camera (button cell) batteries. Special battery-saver circuitry prolongs battery life. The unit can be fabricated using gate array or custom chip technology, which results in extremely small size and low cost of manufacture. A visual indicator (270) allows the user to learn proper operation.
Patent WO-8605052-A1 (WO)
Title: Synchronization recovery in a communications system
Inventor: VAN RASSELL WILLIAM FRANCIS
IPC: H04L7/04
Filed: 1986-02-21
Abstract: Synchronization between a transmitter and a receiver (Fig. 2; Fig. 3) is effected by encoding and transmitting a synchronization pulse as a series of m first waveforms followed by a series of n second waveforms. The first and second waveforms are of the same duration and are transmitted in phase with each other; and m and n are positive real numbers, with m greater than one. The second waveform is different from, and preferably negatively correlated with, the first. When the receiver (Fig. 2; Fig. 3) detects a series of first waveforms in the received signal, it locally generates (212; 312) a series of (either first or second) waveforms and correlates (206; 314; 316; 318) the locally-generated signal with the received signal. A change in correlation is detected as the synchronization pulse.

Title: Multiple-stage coal seam fracing method
Inventor: PERLMAN WILLIAM
IPC: E21B43/27
Filed: 1986-08-13
Abstract: An improved method of multiple-stage hydraulic fracturing of coal seams to improve the rate and total recovery of gas therefrom. In one aspect, the improvement comprises completing the well with 7-inch or larger casing and 3-1/2 inch or larger tubing. In another aspect, the stagewise fracturing is continued until the following quantity of 60-140 mesh proppants has been deposited in the formation: for 5 <= h < 10, m >= 500,000; for 10 <= h < 15, m >= 750,000; for 15 <= h < 20, m >= 1,000,000; for 20 <= h < 25, m >= 2,000,000; and for h >= 25, m >= 3,000,000; wherein h is the vertical thickness of the coal seam in feet and m is the minimum quantity of the fine proppants in pounds deposited therein. In another aspect, a coal seam fractured by the multiple-stage method is refractured after producing or shutting in the well for a period of time to permit closure of the fractures on the proppant placed therein in the earlier multiple-stage fracturing of the coal seam.

Title: Ultra high density pad array chip carrier
Inventor: FREYMAN BRUCE JOSEPH
IPC: H05K7/06
Filed: 1986-12-22
Abstract: An ultra high density pad array chip carrier which includes a ceramic substrate (200) having a plurality of electrical conductors (204, 210) each of which connect to a respective through-hole plugged with solder (206) on its bottom surface. These holder (206) plugs form a pad array for the chip carrier as well as provide a hermetic seal for the ceramic substrate (200). A polymer dielectric layer (304, 600) is affixed to the top surface (212) of the ceramic substrate (200) which provides an insulated metal die mount pad (302, 602) thereon. The electrical conductors (204, 210) on the ceramic substrate (200) are formed using well-known vacuum metallization techniques to achieve much narrower widths. Approximately a 40 percent reduction in overall size and cost is achieved utilizing this improved arrangement, which improves reliability and facilitates post-assembly cleaning of the chip carrier when mounted to its final board.
Patent WO-8707763-A1 (WO)
Inventor: GALLAGHER PATRICK KENT
IPC: H01L21/285
Filed: 1987-05-27
Abstract: Procédé pour fabriquer un dispositif, par exemple un dispositif à semiconducteur, dans lequel on fait réagir au moins deux substances réactives afin de produire un matériau contenant du métal (par exemple 130 et 140; 150) dans une région ou des régions d'un substrat traité ou non traité. Le procédé tient compte du fait que l'une des substances réactives réagira souvent avec un matériau du substrat pour donner des résultats inattendus et très peu souhaitables, par exemple l'érosion presque totale d'éléments du dispositif qui ont déjà été réalisés. Par conséquent le procédé prévoit l'utilisation de l'une quelconque d'un ensemble de techniques afin de réduire la vitesse de réaction entre le matériau du substrat et la substance qui réagit avec celle-ci, tout en évitant une réduction substantielle de la vitesse de réaction entre les deux substances.

IPC: A61K8/00
Filed: 1987-07-15
Abstract: Plusieurs effets du photovieillissement ou des brûlures dues à l'exposition de la peau au soleil, y compris une réduction de la différentiation des cellules épithéliales de l'épiderme et une perte des fibres de collagène, des altérations anormales des fibres élastiques et une détérioration des capillaires dans le derme de la peau sont retardés par l'application topique sur la peau, pendant un programme thérapeutique de soutien, des quantités efficaces de rétinoïdes, y compris de dérivés de rétinoïdes et de stéréoisomères de ceux-ci, de façon à réduire sensiblement et à prévenir des excroissances épithéliales. La peau récupère et retient ainsi sa fermeté, sa turgescence et son élasticité. En outre, par un traitement suivi, les vaisseaux et les cellules sanguines du derme se multiplient, l'épiderme et le derme s'épaississent, ce qui mène à une capacité accrue de la peau à pressentir des irritations ou des blessures, à y résister et à se récupérer de celles-ci. L'hyperpigmentation, les lignes et les rides dues au vieillissement sont également réduites. Le traitement est particulièrement utile pour la peau du visage d'un être humain et on applique de préférence des quantités insuffisantes pour causer une irritation excessive.

Title: Electro-optic measurement (network analysis) system
Inventor: NEES JOHN
IPC: G01R27/28
Filed: 1988-02-05
Abstract: A measurement system using electro-optic sampling and operative in the time domain characterizes devices over a bandwith extending to upper microwave frequencies (e.g., 100 CHz). The device under test is mounted to or integrated on a substrate (10, 12) of electro-optica semiconductor material and is connected to transmission, lines (14, 16) on the substrate. Sampling signals are electro-optically generated and propagate along the lines toward and away from the device under test, using a laser pulse beam incident on the substate. The signals are electrically sampled by a laser pulse sampling beam. The sampled waveforms are processed by subtracting (58) the waveform, corresponding to the signal incident on the tested device, from the waveform corresponding to the sum of the incident and reflected signal and Fourier transforming (62) to derive the scattering parameters.

Title: Improved side gear mounting for differential assembly
Inventor: PEDERSEN HARRY
IPC: F16H48/29
Filed: 1988-10-17
Abstract: A differential gear assembly of the type including worm or helical-type gears mounted on crossed non-intersecting axes is provided wherein a pair of drive axles (12, 14) are received in bores (10) formed in the sides of a differential housing (4), and wherein axially aligned worm or side gears (18, 30) are coupled to each axle end for meshing engagement with torque transfer gears within said housing. One of the side gears (30) is provided with an outwardly directed flange (36) which overlaps an inwardly directed flange (42) associated with the housing to maintain the end faces of the side gears (18, 30) out of contact with each other to preclude axial thrust forces developed in one side gear (30) from passing to the other (18) and to eliminate frictional forces at the interface of the side gears, thereby reducing differences in bias ratios associated with opposite directions of differentiation without significantly reducing the overall bias ratio of the assembly.

Title: Chilling assembly line workpieces by cryogen counterflow
Inventor: STEARNS THORNTON
IPC: B23P11/02
Filed: 1989-07-13
Abstract: Workpieces (e.g. valve seats, valve guides, or cylinder liners for an internal combustion engine) are chilled as they are supplied to a station on an assembly line (50) using a feeder/chiller that includes a passage (32) to convey workpieces downwardly from a location at the top of the passage to an assembly line station (50). The chiller/feeder is fed cryogen from a reservoir of liquid cryogen. Because cryogen fluid (chilled nitrogen vapor) entering the passage (32) is denser than air, downward flow of cryogen fluid must be restricted. For example, the passage (32) includes a constriction (34) below the position at which cryogen is fed to the passage (32). The constriction (34) is configured and sized to allow workpieces to move through the constriction (34), yet the constriction (34) is small enough to restrict the downward flow of cryogenic fluid when a workpiece is positioned in the constriction (34).

Abstract: Système d'ordinateur interactif dans lequel de grandes quantités d'images vidéo et de signaux audio de grande qualité sont reproduites simultanément, et dans lequel des images individuelles d'un disque vidéo (30) sont visualisées sur le moniteur du système (40) pendant des périodes de temps déterminées, pendant que des sons isolés et des mots en provenance d'un CD/ROM (20) sont reproduits par le haut-parleur (50) du système. Les signaux audio émis par le disque vidéo (30) et par l'unité centrale de l'ordinateur (10), ainsi que les images infographiques fixes (41) ou animées (42), sont également disponibles. Un mécanisme ''barre de commande'' (60) assure une interface appropriée qui isole l'utilisateur des différentes sources d'informations audiovisuelles, lui permettant de se concentrer sur les informations proprement dites. L'apparence d'intelligence que l'utilisateur voit dans le système est due en majeure partie à un mécanisme ''brasseur'', lequel sélectionne un composant audio et/ou visuel particulier en fonction d'un ''niveau de performance'' déterminé par l'interaction entre l'utilisateur et le système.

Title: Treatment of aluminum reduction cell linings combined with use in aluminum scrap reclamation
Inventor: GARDNER OWEN M
IPC: C22B21/00
Filed: 1989-12-04
Abstract: Spent potlinings from aluminum reduction cells are fed to an aluminum reclamation furnace (10) as a partial replacement for or supplement to the molten salt flux used in the reclamation process. This rids the spent potlinings (14) of materials which would leach into soil or groundwater if the potlinings (14) were otherwise disposed of at dumpsites, rendering them suitable for dumping with no hazard to the environment. Benefits to the reclamation process may be had at the same by substituting the less expensive potlinings (14) for the salt flux materials and by using the fuel potential of the potlinings (14) to reduce the external fuel requirement.
