Patent EP-0298936-B1 (EP)
IPC: C04B35/64
Filed: 1988-04-27
Granted: 1993-10-06
Abstract: This invention relates to sintered ceramic materials in which the densification during sintering takes place with a liquid phase preferably based on silicon nitride. During sintering such materials are often embedded in a powder of inert material such as BN etc. The invention resides in the fact that by embedding the material to be sintered in a protective powder with a composition similar to that of the intergranular phase a surface zone with a composition and/or structure different from that of the core can be obtained.

Title: Device for measuring distances between an optical element with high chromatic aberration and an object
IPC: G01B11/02
Filed: 1988-06-21
Granted: 1992-03-25
Abstract: In a process for measuring the profile of an irregular reflecting surface as a function of the distance between each point of this profile and a polychromatic light source, a flat beam of light is produced from the light from this source, for example, and represented on the profile by a chromatic lens element. The height of the profile is derived from the differentially coloured light strips so formed. The relief of the object is reconstructed by analysis with a spectral dispersion apparatus.

Abstract: An improved method of operating a membrane separation system is provided, which comprises applying a reduced pressure to one side of the or each membrane to thereby cause fluid to be drawn through the or each membrane from the other side thereof. As the method does not utilize fluid under pressure, which has typically been required in prior art procedures, the risk of damage to the membranes is eliminated, or at least minimised.

Abstract: A precision liquid dispenser comprises a positive displacement diaphragm pump and a hydraulic system for selectively deforming the diaphragm. The diaphragm pump comprises: pump body 109, pump cavity 110, pump diaphragm 111, and pump input/output port 117. A solenoid operated valve assembly 125 selectively connects the port 117 to a source of liquid to be dispensed 113 and to an output filter 123. A hydraulic system for selectively deforming diaphragm 111 comprises: body 104 with cavity 106, piston 107, sealing ring 108 and hydraulic fluid in the space between the top of piston 107 and diaphragm 11. The position of piston 107 is controlled by the stepping motor 102 and the mechanical coupling of the output shaft of the motor to the piston 107, Mating threads on the shaft 120 and on the interior of the member 121 convert rotary motion of the motor output shaft to linear motion of the piston 107. The volume of fluid dispensed per cycle of dispenser operation is determined by the number of pulses applied to the stepping motor 102; and the output flow pattern as a function of time is controlled by the pattern of pulses applied to motor 102 by the control logic 150. The solenoid valve assembly 125, under the control of signals from the dispenser control logic 150, selectively connects the valve input port 115 to the valve input/output port 116, or connects the input/output port 116 to the valve output port 112. Valve control signals from control logic 150 are coordinated in time with control signals for the reversible motor 102 over path 151.

Abstract: On connaît un mécanisme de direction véhiculaire de structure excessivement complexe, qui déplace une soupape de commande de rotation à gauche ou une soupape de commande de rotation à droite par l'intermédiaire de cames séparées, en réaction à la rotation d'un volant. Le mécanisme de direction (42) décrit est plus simple, plus économique et plus compact car il comporte un arbre d'entrée (92) et une seule came d'actionnement (94) qui sont conjointement rotatifs à l'opposé d'une position neutre dans l'une ou l'autre direction. Une came d'actionnement (94) définit une fente de guidage profilée (96) sensiblement en spirale, et un ensemble contre-came (98) coopère avec celle-ci et comprend une roue à galet (100) qui fait office de poussoir de came et est logée dans la fente de guidage profilée (96).

Abstract: Une pseudo-variance locale pondérée centrale dans le voisinage d'un pixel d'image détermine le facteur d'amplification multipliant la différence entre le pixel d'image et son homologue flou avant qu'il ne soit combiné avec l'image originale. Le facteur d'amplification est calculé pour chaque pixel se trouvant dans l'image, et varie d'une valeur minimum d'environ -1 lorsque la variance pondérée centrale se trouve à une valeur minimum, jusqu'à une valeur maximum donnée lorsque la variance pondérée centrale atteint une valeur maximum. La pseudo-variance pondérée centrale est calculée par convolution du voisinage local entourant chaque pixel d'image à l'aide d'un noyau de poids centraux ayant une valeur maximum au niveau du pixel central. La pseudo-variance pondérée centrale est la différence entre la moyenne pondérée centrale du carré du voisinage local des pixels d'image et le carré de la moyenne pondérée centrale. On parvient à obtenir à la fois la netteté d'image et la suppression du bruit dans la même image, en permettant au facteur d'amplification de varier entre une fraction d'unité et au delà de l'unité à mesure que la variance pondérée centrale varie d'une valeur faible (image uniforme) à une valeur supérieure (image texturée).

Abstract: A fixation system for tubular bone fractures (3, 4) consists of an elongated, flattened fixation element (20) and bone screws (10) connected to each other by means of a screw (11), a cone (16) and a conical segment section (15). The fixation element (20) has an essentially rectangular cross-section and is made of tissue-compatible, high-strength material, in particular implant steel. At least two holes in each of the two end sections (21) of the fixation element (20) extend through its opposing wide faces. The bone screws (10) are inserted through these holes. The fixation element (20) is made in one piece from the two relatively rigid end sections (21) and an intermediate connecting section between them, or from two superimposed parts connected to each other in the end sections. The connecting section (31) is elastic in comparison with the end sections (21), because its cross-section is smaller than that of the end sections (21). This compact fixation device can be implanted under the skin and eliminates transverse forces as well as flexing and torsional moments in the region of the fracture, without the implantation affecting the circulation. In addition, the normal forces in the fracture region can be adjusted as required.

Abstract: The present invention is directed towards the production of a single crystal semiconductor device mounted in intimate contact with a polycrystalline CVD diamond substrate which allows the high heat conductivity of diamond to keep the device cool. This device is made by a method comprising the steps of placing in a reaction chamber, a single crystal of silicon heated to an elevated CVD diamond-forming temperature. A hydrocarbon/hydrogen gaseous mixture is provided within the chamber and is at least partially decomposed to form a polycrystalline CVD diamond layer on said silicon. During this deposition/growth phase, an intermediate layer of single crystal SiC has been found to form between the single crystal of silicon and the polycrystalline CVD diamond layer. In the next step of the process, the silicon is etched or removed to reveal the single crystal SiC supported by the polycrystalline CVD diamond layer. Finally, a semiconductor layer (e.g. silicon, SiC, GaAs, or the like) is grown on the exposed single crystal of SiC to produce a single crystal semiconductor polycrystalline CVD diamond mounted device.
