Abstract: In a gradient coil set for a magnetic resonance system, the y gradient coils 102, 104 are located substantially closer to the patient than are the x and z gradient coils. As a result, one may design the y gradient coils to produce a stronger y gradient, to have reduced inductance or otherwise better tailor the magnetic/electrical properties of the gradient coil set for MRI imaging sequences. In the exemplary embodiment, at least portions of the y gradient coils have a first spacing from the z-axis while the x and z gradient coils have a second substantially larger spacing from the z-axis. Furthermore, while the x and z gradient coils are centered about the z-axis in the patient access space, alternate sides of the y gradient coil set are centered about respectively off-set centers C˝ y , C′ y  vertically displaced from the z-axis center of the patient access area. The result is a substantially rectangular or elliptical patient access opening 100 with horizontal dimensions defined by the x, z coils sets and vertical dimensions defined by the y coil set.

Abstract: An envelope is described with a closing and sealing device (1), comprising a closed end (25) and transverse opening (26) in the region of the other end, and a flap (27) which extends beyond the opening in the form of a continuation of at least one side of the envelope. The flap is for­med with a series of orifices (28, 29) as is also the body of the envelope ad­jacent said opening (30). Such orifices are positioned to co-operate with locking pins (5) and co-operating female formations (15) present on the closing and sealing device which is wrapped in said flap. 
     The device may then be doubled over itself to close the ope­ning of the envelope, the locked end of the pins being inaccessible from outside due to the whole device being wrapped in or covered by the material of the flap.

Abstract: A transmission unit (1) for motor vehicles is described, in which a continuously variable belt transmission (8) is in driven connection with, on the one hand, a primary shaft (5) and, on the other hand, with a secondary shaft (12) arranged parallel thereto. The primary shaft (5), on the input drive side, is connected via a torque sensor (7), a starting clutch (6) and a wheel set (4) to an input drive shaft (2). The latter is arranged on the same axis as an output drive shaft (3). The secondary shaft (12) is connected on the output drive side to an epicyclic transmission (13) which allows the direction of rotation to be reversed via a single friction clutch (19). As a result of the allocation of the epicyclic transmission (13) on the output drive side to the belt transmission (8), the torque on the belt transmission (8) is not increased when driving in reverse. An annular wheel (16) of the epicyclic transmission (13) drives a wheel set (18) which is connected to the output drive shaft (3) in a manner compensating for the axis offset. The torque sensor (7) is located in a space-saving manner inside the starting clutch (6). <IMAGE>

Abstract: A cuvette has a base (9) which can be inserted into it from above, and a lid (10) which can be pushed in from above in a telescopic fashion. The base (9) sits on tabs (5-8) on the lower edge of a sleeve (1) of the cuvette designed as a tensioning strip. When duplicating, the working model is placed on this base (9). When covering over, that is to say when producing the casting mould, the embedded mass model produced previously in the cuvette is placed instead of the base (9) into the cuvette. The cuvette is thus a duplicating mould and muffle moulder. <IMAGE>

Abstract: The color original image is pre-scanned in order to detect respective color components of sample pixels. Then, it is judged whether or not each sample pixel has color components corresponding to a designated memory color under a predetermined allowable error. When the number of sample pixels having the memory color is larger than a threshold value, a predetermined color separation rule is corrected to obtain a corrected color separation rule which is actually used for separating the color original image into components for image reproduction thereof.

Abstract: A memory element is formed of a thin film tran­sistor. The thin film transistor has a semiconductor layer (4), a source electrode (6) electrically connected to the semiconductor layer, a drain electrode (7) elec­trically connected to the semiconductor layer and formed separately from the source electrode, a gate electrode (2) for controlling formation of a channel of the semi­conductor layer, and a gate insulation film (3) for iso­lating the gate electrode (2) and the semiconductor layer (4) from each other and causing a hysteresis in the relation between the drain current and the gate circuit. The insulation film is a silicon nitride film whose composition ratio of silicon to nitrogen is in a range of approx. 0.85 to 1.1. According to this invention, the relation between the gate voltage and the drain current can be set to have a hysteresis. Therefore, the thin film transistor can be used as a memory element. Further, according to this invention, data can be written, erased and read out by selectively applying an electric field to the gate insulation film. Therefore, the thin film transistor can be used as a memory element.
