Abstract: An automated magnetic field shimming process for magnetic resonance spectroscopic imaging (MRSI) uses doubly phase encoded NMR spin echo responses in conjunction with multiple fourier transformation to derive a spectroscopic plot for each voxel in a three-dimensional array of voxels in an image volume (including portions of a living subject) which is to be subsequently subjected to MRSI using NMR FID or spin echo responses. The thus derived hydrogen peak frequency is taken as a measurement of existing static magnetic field intensity within that voxel and adjusted shim coil currents are calculated so as to reduce or minimize nonuniformity of the static magnetic field. A nonexistent pseudo shim coil having an assumed uniform shim contribution may enhance the resulting field homogeneity. The auto shimming procedure may be applied iteratively as required to achieve the predetermined degree of field uniformity.

Abstract: A spring (17) acts constantly on the upper part (9), which is vertically adjustable by means of a spindle (8), to compensate the weight of the vertically adjustable parts. An additional compensation spring (24) acts via a piston (25) on the upper part (9). By means of a screw (28), which can be screwed to a threaded bore (31), the piston (25) can be coupled to the base (1), which is not adjustable in height, hence cancelling out the effect of the additional compensation spring (24). A plurality of additional compensation springs can be provided, and can selectively be made active or inactive in order to be able to compensate different weights.

Ledit composé présente une plage nématique extrêmement étroite et une transition de phase à bas point de fuison; il contient au moins deux composants, c'est-à-dire le composant A comprenant au moins un 4-n-alkyl-4'-cyanobiphényle représenté par la formule générale (I) (dans laquelle R1 représente un groupe alkyle comportant 8, 9, 10, 11 ou 12 atomes de carbone) et le composant B comprenant au moins un 4-n-alkoxycarbonyloxy-4'-cyanobiphényle représenté par la formule générale (II) (dans laquelle R2 représente un groupe alkyle comportant 8, 9, 10, 11 ou 12 atomes de carbone), dans un rapport entre le composant A et le composant B compris entre 25:75 et 95:5. Etant donné que ce composé peut présenter une plage nématique inférieure ou égale à 2°C, il permet une écriture rapide sur un élément d'affichage et améliore le contraste d'une image projetée, ce qui améliore notablement la qualité d'affichage. En outre, ce composé est utilisé avantageusement dans un affichage à cristaux liquides à écriture thermique destiné à fonctionner à température ambiante, car il présente un point de fusion inférieur ou égal à 0°C.

The optical coupling units (12) are formed into stages. The number of optical coupling units (12) or stages determines further coding of each bit of the input optical signal or code sequence. Stages can be coupled together to process a sequence of optical pulses corresponding in number to the number of optical coupling stages in the system. The outputs of each stage are coupled via optical switches (18) to an optical summing device (24) to simultaneously process the coded data and determine whether the processing has resulted in matching or mismatching of data.

Abstract: The brake system (10) has an electric control circuit (III) with a control device (36) by means of which pressure control valves (27 to 30) which are located in the pressure medium brake circuits (I, II) for wheel brake cylinders (17 to 20) can be controlled. The wheel brake pressure on at least one vehicle axle (e.g. 12) which can be controlled in a load-dependent manner can be varied as a function of the activity of the anti-blocking function on this vehicle axle (12) and/or further vehicle axles (e.g. 11); When the anti-blocking function at the axle (12) which can be controlled in a load-dependent manner is actuated, the brake pressure at this axle is reduced, and, on the other hand, when the anti-blocking function on the other vehicle axle (11) is activated it is increased. When a greater degree of deceleration of the vehicle is desired and the anti-blocking function on the axles (11, 12) is not activated, the wheel brake pressure on the vehicle axle (e.g. 12) which can be controlled in a load-dependent manner is increased. As a result, sensors for detecting the axial load of the vehicle can be dispensed with. The invention can be applied in particular in utility vehicles. <IMAGE>

By adjusting the position of rollers (8) of bending mould (10) in vertical direction a glass sheet is bent to a desired curvature while heating it in furnace mould station (3). The roller mould (10), along with its bent glass sheet (9′), is carried out of furnace (1) and into a chilling station. When using a transferable and adjustable roller mould (10), the apparatus does not set limitations for the size or degree of bending of glass sheets to be bent.

Abstract: A ceramic sinter whose mother phase substantially satisfies a sialon composition. This sialon containing ceramic sinter contains at least one kind of compound selected from the group of oxides, carbides, nitrides, and silicides of hafnium, niobium, or titanium in the range of from 0.2 to 40 weight %. The compound of hafnium, niobium, or titanium is present independently in the mother phase in particle-­dispersive form. The dispersed particles contribute to improving the mechanical strength, fracture toughness, and heat impact resistance because the sinter body is reinforced by dispersion. The sialon containing ceramic sinter is so excellent in high-temperature properties that it is suitable for use in high-temperature structural materials. Further, a β-type sialon containing ceramic sinter made by forming and firing a ternary material powder of silicon nitride, aluminum oxide, and hafnium compound not only is excellent in improved effects but also has an ample freedom in shaping because a slip casting method can be applied.
