Abstract: A magnetic resonance method is known with cycles comprising a 90° excitation pulse and gradient recalled echoes wherein after each excitation and sampling of the recalled echoes a waiting time is introduced for having magnetization return to thermal equilibrium. In said method the cycles are applied with a time integral of a phase encoding gradient getting successive magnitudes from a minimum to a maximum value in a number of successive cycles in order to obtain data for forming an image e.g. representing proton densities in an object to be examined. 
     A magnetic resonance method is suggested with α° excitation pulses where 0<α<90°, and gradient recalled echoes whereby there is no substantial waiting time between successive excitation cycles, so that a steady state equilibrium of magnetization will occur, and whereby a best possible image quality is obtained by assigning magnitudes in a sequence of decreasing absolute values over a number of measurement cycles. Signal sampling takes place from the first measurement cycle i.e. there is no waiting for steady state conditions. This implies e.g. amplification of the highest image frequencies giving a better edge definition in the image so that image quality is improved.

Abstract: A method and apparatus for improving the quality of an electronic image generated by a charge coupled device (CCD) array (28) that senses scene images through a prism (28A, 28B) or prismatic filter movable into and out of the path of image-containing light rays impinging on the colour filter overlying the CCD array that alternately shifts the scene image between colour filters of the CCD array that absorb particular scene image colours and those that transmit these colours to their associated CCDs while in the case of the prismatic filter absorbing the dominant scene colour generated by the coloured optical filter. Scene image signals generated by a CCD array (18) in this manner are processed such that their spatial relationship with respect to the second scene image is precisely monitored and electronically counter-shifted for subsequently scene image reconstruction. By shifting the scene image between individual CCDs having different colour optical filters, most of the CCDs in the CCD array can generate image signals for two different scene colours or scene colour combinations and thereby improve the image resolving capabilities and/or the colour balance of electronic images generated by the CCD array.

Title: Electronic detector for a logic binary level
Inventor: KOWALSKI JACEK
IPC: G06F21/86
Filed: 1988-07-01
Abstract: To avoid the fraudulent activities of malevolent users, detection of the secret codes contained in a MOS integrated-circuit memory card, and transmitted to an input/output unit, is prevented by interposing in the transmission chain, in the integrated circuit itself, a read amplifier (50) essentially comprising two identical circuits (4, 5) in parallel and which are intended to take complementary logic states when they receive a same logic level to be detected. This results in the electrical consumption of the amplifier being the same whatever logic level is transmitted. Under these conditions it becomes impossible to deduce the nature of the logic level transmitted. As an improvement, the outputs of the detector are provided with bistable circuits (15, 18) and are mutually coupled (19, 20) to one another so as to be able to take account of detected information of transient or corrupted type.

Abstract: An acrylic multifilamentary material possessing an internal structure which is particularly suited for thermal conversion to high strength carbon fibers is formed via a specifically defined combination of processing conditions. The acrylic polymer while in substantially homogeneous admixture with appropriate concentrations of acetonitrile, C₁ to C₄ monohydroxy alkanol, and water is melt extruded and is drawn at a relatively low draw ratio which is substantially less than the maximum draw ratio achievable. This fibrous material which is capable of readily undergoing drawing is passed through a heat treatment zone wherein the evolution of residual acetonitrile, the monohydroxy alkanol and water takes place. The resulting fibrous material following such heat treatment is subjected to additional drawing to accomplish further orientation and internal structure modification and to produce a fibrous material of the appropriate decitex for carbon fiber production. One accordingly is provided a reliable route to form a fibrous acrylic precursor for carbon fiber production without the necessity to employ the solution-spinning routes commonly utilized in the prior art for precursor formation. One can now eliminate the utilization and handling of large amounts of solvent as has heretofore been necessary when forming an acrylic carbon fiber precursor. Also, acrylic fiber precursors possessing a wide variety of cross-sectional configurations now are made possible which can be   thermally converted into carbon fibers of a similar cross-sectional configuration.

Abstract: Both aluminum scrap covered with a volatile coating and a heated airstream having a low oxygen content pass through a kiln (2) where the airstream causes the coating to volatilize. The temperature of the airstream, where it enters the kiln, is maintained essentially constant, slightly below the melting temperature of the aluminum, and likewise the temperature of the airstream is maintained es­sentially constant where the airstream leaves the kiln (2) , this being achieved by varying the mass flow of the airstream to compensate for variances in the nature and mass of the aluminum scrap within the kiln (2). Beyond the kiln the airstream enters an afterburner (8) where it is heated in the presence of sufficient oxygen to effect combustion of the volatile components of the coating. The airstream then passes through a heat exchanger (12) and back to the kiln (2). The mass flow within the kiln (2) is controlled by diverting some of the airstream upstream from the heat ex­changer (12) or by varying the speed of the fan (6) which creates the airstream.

Abstract: Porous shaped articles made from a molded composite of ultra high molecular weight polyethylene and polyethylene wax are disclosed. These articles are produced by free-sintering a non intensively mixed blend of UHMW-PE particles and particles of a polyethylene wax. The process involves mixing the UHMW-PE and wax both in powdered form until a heterogeneous mixture is formed, but under conditions which do not lead to any substantial fracturing of the UHMW-PE particles or melting of either component. The heterogeneous mix is then transferred to a press mold to form a shape and pressure is applied sufficient only to maintain the enclosed volume of the shape. The mold is heated to a temperature above the melting point of the UHMW-PE for a period of time to allow the particles to soften, expand, and contact one another at their surfaces. The mixture is then quickly cooled. 
     Porous articles so produced may exhibit stiffness values in excess of about 2000 psi while at the same time showing excellent porosity values of less than about 25 inches water pressure drop.

Abstract: A flash EPROM cell is fabricated using a two polysilicon enhancement mode n-channel transistor process. An active transistor region is formed in a silicon substrate (14) by growing a field oxide (16) around the region. A first polysilicon layer is deposited, etched, and oxidised to form an insulated control gate electrode (18). A second polysilicon layer is deposited over the active transistor region and the control gate electrode (18) and then anisotropically etched to remove all of the second polysilicon material except for a filament (20) adjacent to the control gate electrode (18), which forms a floating gate electrode (20). Source and drain regions (10, 12) are formed in the active transistor region with the control gate electrode (18) and the floating gate electrode (20) positioned over the channel region interconnecting the source and drain regions. The cell is programmed by hot electron channel current injection by proper voltage biasing of the control gate electrode (18) and drain (12). The cell can be either symmetrical or asymmetrical depending on the configuration of the floating gate filament electrode (20).
