Abstract: The flange-like lid rim of a packaging container, including the outwardly projecting gripping part shaped thereon, is laterally enclosed by an all-round rim portion, so that it is not accessible for opening the packaging container. The actuation of the gripping part leads to the separation of a rim extension of the container body engaging below the gripping part and to which the latter is non-detachably connected by a pushbutton connection. The sealing fixing of the lid to the container body takes place by interlocking engagement beads. The packaging container avoids any hot sealing joint as a guarantee seal and is made from completely burnable plastic.

Abstract: Nuclear fuel elements are provided that are resistant to pellet-clad interaction. The closed end nuclear fuel elements comprise a zirconium or zirconium alloy tubular cladding (3) that has a layer of lubricant (7), preferably graphite, on the inner surface (5) thereof, and enriched uranium dioxide pellets (9) that have a coating (15) on the outer surface (13) thereof of a thick­ness sufficient to absorb fission products. The coating (15) on the pellets (9) may be a burnable absorber or a material that has a relatively low neutron absorption compared to a burnable absorber. The combination of the layer (7) on the tubular cladding (3) and the coating (15) on the pellets (9) reduces both the stress level and the concentration of damaging fission products that would contact and react with the layer of lubricant (7) about the inside surface (5) of the tubular cladding (3) and thus reduces conditions for pellet-clad interaction.

Abstract: A filter comprises an amplifier circuit arrangement having a signal input (1) and a signal output (8) and a coupling (36) between a point (37) on a signal path (39) to the signal input and a point (38) on a signal path from the signal output. The amplifier circuit arrangement comprises an inverting amplifier (6) to the input (5) of which the signal an input (1) is connected via a series impedance (7), e.g. a resistor. A feedback impedance (9), e.g. a capacitor, connects the amplifier output (8) to its input (5) so that this input constitutes a virtual earth. The phase relationship between the input and output signals of such an arrangement changes from inverting to non-inverting at frequencies at which the gain of the amplifier drops to below unity, because of forward feed through the feedback impedance (9), thereby upsetting the phase relationship between the signals passing through the arrangement and those passing through the coupling. Accordingly a further impedance (10), e.g. a capacitance, is provided between the common point (11) of the series and feedback impedances and ground. At frequencies at which the amplifier gain is high this has virtually no effect, because of the virtual earth existing at the common point (11). However, at frequencies at which the amplifier gain drops to unity or below the virtual earth effect is lost and the further impedance forms a potential divider with the series impedance (7), reducing the proportion of the input signal which can take the direct forward path through the feedback impedance.

Abstract: Apparatus suitable for processing semiconductor slices, the apparatus comprises a tank (1) for receiving a jig carrying semiconductor slices, a first supply line (2) for supplying a processing liquid to the tank (1), a supply valve (3) for controlling liquid supply through the first supply line (2), the supply valve (3) being operable in response to changes in fluid pressure at a control port (4) of the supply valve (3) and a second supply line (5) for supplying fluid to the control port (4) to control operation of the supply valve (3). The second supply line (5) communicates with an inlet (8) of the tank (1) via a control valve (7) which is operable in response to changes within the tank to control the fluid pressure at the control port (4) and so control operation of the supply valve (3). 
     In the arrangement shown in Figure 1, a valve member (7a) of the valve (7) is carried by a platform (9) pivotally mounted within the tank (1). The weight of a jig carrying semiconductor slices acting on the platform (9) causes the platform (9) to tilt to close the control valve (7) thereby increasing the fluid pressure at the control port (4), causing the supply valve to open and so supply liquid to the tank via the inlet (1ʹ).

Abstract: In processing plate-type objects, especially semiconductor chips, for example in vacuum technology, they are often heated to elevated temperatures. It is then desirable to apply the thermal energy in a controlled and homogeneous manner. In other cases it is necessary to cool the chips in a controlled and uniform manner. 
<??>Gas conduction technology is known to make possible a so-called thermal coupling between two adjacent surfaces and this can be combined with the advantages of thermal transfer by gas conduction. The invention makes full use of the advantages of this gas conduction heat transfer for the transfer of heat between a backplate and a chip and in doing so avoids the disadvantages of a mechanical loading by prestressing the chip. For this purpose, a gas is used both as a gas cushion to improve the heat transfer between chip and backplate and also to press the chip onto the backplate avoiding a mechanical loading.

Abstract: A magnetic resonance imaging method and apparatus wherein a spin echo (52) and a gradient echo (60) are generated in each magnetic resonance sequence repetition. The spin echo is phase encoded by a phase encode gradient (44) in regular steps spanning about a quarter of k-space. More particularly, steps from -n to G max /2, where n is a small integer and G max  is the maximum phase encode gradient. An off-set phase encode gradient (58) shifts the phase encoding of the gradient echo by G max /2 relative to the first phase encoding gradient. Data to fill the empty portions of k-space (142, 267) between -n and-G max  are generated from the complex conjugate (140, 160), of the first echo data (74) and the second echo data (76). The first and second echo data and the complex conjugate data are transformed (122, 132, 146, 166) to generate parted image representations (124, 134, 148 168). The first echo image representation and the corresponding conjugately symmetric image representation are phase correction (126, 150) in accordance with a phase map (112) derived from the central most first echo data (78). The partial image representations are summed (170) to produce a resultant image representation (172).
