Abstract: A flexible manipulator is constructed of parallel elements which are layered one over the other along a stacking axis and preferably have at least three bores on the circumference, which are aligned to form a guide arrangement. Projecting sleeves are provided at the bores and extend telescopically into one another from respectively two adjacent elements. Elastic rods are guided through the bores, which rods are fastened at one end of the manipulator and exit freely at the other. The manipulator can be brought into an arbitrary shape through the tension and pressure created by displacing of these rods in a particular manner. In addition, a blocking material is provided in the invention which can lock the sleeves of adjacent elements from movement so that a displacement of a rod will be directed between a different pair of elements. The locking or blocking of the movement of the sleeves can be obtained by utilizing the rotation of the actuating rods.

Abstract: An anti-theft system for a motor vehicle includes a portable code transmitter which transmits a code signal from a distance upon actuation. A receiver unit in the motor vehicle receives the code signal and evaluates it. Upon authorization, only the engine is started, but the vehicle does not have to be unlocked. A further code signal is required in order to drive the vehicle. However, it must be generated in the vehicle interior. Thus the engine can already warm up without the user being located in the vicinity of the vehicle.

Abstract: The MOS transistor has field plates and a subarea of the gate formed from the same polysilicon layer. A gate oxide lying underneath them is produced at the beginning of the fabrication process and it therefore exhibits particularly high quality. The polysilicon in the active area is raised to the same level as the adjoining field oxide areas, resulting in a planar topology.

Abstract: In an arrangement for signal transmission between chip layers of a vertically integrated circuit, a defined, capacitive signal transmission ensues between a part of the vertically integrated circuit in one chip layer and a further part of the vertically integrated circuit in a further chip layer by means of a coupling capacitance. Particularly given high connection densities, a large number of freely placeable and reliable vertical signal connections can be produced directly from the inside of one chip layer to the inside of a neighboring chip layer without extremely high demands being made on the adjustment of the chip layers relative to one another and on the surface planarity of the individual chip layers.

The therapy apparatus preferably contains an ultrasound source that can be transesophageally applied.

Abstract: A digital signal processor employable for utilization for speech processing or for some other pattern recognition overcomes the weaknesses of digital signal processors given the subtraction with following amount formation that must often be implemented in these applications, an auxiliary hardware is provided that contains the feature vector that is to be compared to reference feature vectors from the dictionary in a separate memory. The calculating work is thereby implemented by a separate arithmetic unit that provides a separate difference-forming and amount-forming unit for each feature comparison. The number of clock cycles of the digital signal processor required per comparison can be dramatically reduced by the invention. A suitable addressing method thereby assures that it is always corresponding features of the individual feature vectors that can be compared to one another.

Abstract: In order to avoid sticking effects before a movable micromechanical structure is laid bare, in a production method for a micromechanical component with a movable structure, the structure is joined to a suitable mount, such as the substrate, through an auxiliary structure, and this auxiliary structure is not removed until after the movable structure is laid bare. This method is compatible with IC production processes for integrated circuits.

Abstract: A system for controlling control rods which can be moved into and out of a reactor core of a nuclear power plant, includes a selector device, a monitor device and a rod control device. The selector device contains travel sequences which are selectable and defined for regulating the nuclear power plant, i.e. allocation and movement sequences of the control rods, and it transmits the selector signals allocated to each travel sequence to the rod control device. The monitor device checks the selector signals for acceptability while taking into account the structural features of the reactor core and the control rods, which are allocated to the respective travel sequence, in particular proximity relationships of the control rods. If the selector signals are acceptable, an enable signal is transmitted to the rod control device and the rod control device induces a displacement of the control rods according to the selector signals.

The DRAM cell arrangement can be produced with a storage-cell area of 4F.sup.2 by using only two masks, F being the minimum producible structure size in the respective technology.

Abstract: An optical coupling arrangement consist of a pair of strip-type optical waveguide end segments extending alongside one another and having ends arranged at a small distance from each other so that crosstalk can occur. In order to suppress the crosstalk at a point spaced from the ends of each of the end segments, the segments are arranged so that the distance from one another increases from the distance at the end as the distance from the end along said segments increases.

Abstract: Capacitors, in particular stacked capacitors for a dynamic memory cell configuration are manufactured by first forming a sequence of layers, which include layers made of a first conductive material alternating with layers made of a second material. The second material can be selectively etched with respect to the first material. Layered structures are formed from the sequence of layers, with the flanks of the layered structures each having a conductive support structure. The layered structures are formed with openings, such as gaps, in which the surface of the layers is exposed. The layers made of the second material are selectively removed with respect to the layers made of the first material. The exposed surface of the layers made of the first material and of the support structure are provided with a capacitor dielectric, onto which a counter-electrode is placed. The capacitor is made by etching p.sup.- -doped polysilicon that is selective to p.sup.+ -doped polysilicon.

Abstract: In a nuclear magnetic resonance tomography apparatus and a method in the form of a pulse sequence for operating the apparatus, after an excitation of spins in a subject, two groups of nuclear magnetic resonance signals are obtained in two time intervals at different chronological spacings from the excitation time. An image is obtained on the basis of the signal differences of nuclear magnetic resonance signals of the first and second groups with corresponding locus-encoding. Signal contributions from tissues with longer T2 relaxation time can thereby be screened out.
