Abstract: A layout of a sense amplifier configuration for a semiconductor memory is described. The layout has a plurality of read/write amplifiers, extending as strips in the form of rows one under the other, and having NMOS and PMOS transistors. At least one of the two driver transistors is disposed with its doping regions between the associated NMOS or PMOS transistors of the read/write amplifiers. A gate of the driver transistor is configured as a two-strip gate, in order to accelerate the signal evaluation in the sense amplifiers.

Abstract: A shaft bearing system having a housing including a spherical collar for the shaft. The shaft bearing is made up of a cage (19) into which the spherical collar (20) is inserted. The cage is installed in a recess (18) in a housing (16); a sleeve (21) is arranged in the interior of the spherical collar, and an axle stub (22) is inserted into the shaft bearing. The rotational movement preferably takes place between the sleeve (21) and the axle stub (22). The use of the spherical collar in a shaft bearing made up of a cage and a guide bushing has the advantage of greater flexibility in selecting the material or materials from which the housing and the rotatable component installed therein may be formed. The shaft bearing of the invention is particularly useful for accommodating a centrifuge rotor (10) in a centrifuge housing (16).

Abstract: A semiconductor memory of the dynamic random access type (DRAM) includes memory cells combined in addressable units of bit lines and word lines. Each memory cell array is allocated a row decoder for selection of one of the word lines and a column decoder for selection of one of the bit lines, in the memory cell array. The row decoder is connected to a row selection signal line for transmission of a selection signal. The row decoder is disposed at an edge of the memory cell array allocated thereto, and between the memory cell arrays. The column decoder is connected to the row selection signal line. The column decoder is disposed on the outer edge area both of the memory cell array allocated thereto and of the memory field.

Abstract: A bar device has one end portion supporting a test body and is pivotable about a pivot center. The bar device comprises a measuring device together with a probe, which works on the basis of measuring the thickness of thin layers. An energizing means acts on the bar device and comprises a first part rigid with a housing and a second part rigid with the bar device. A geometric first longitudinal axis passes through the center of the probe and the center of the test body. The part rigid with the housing comprises a cylindrical electromagnetic coil having a geometric second longitudinal axis parallel with the first longitudinal axis. The coil has a clear space parallel with the second longitudinal axis. Substantially coaxial with the second longitudinal axis, a carrier rod is rigid in its longitudinal direction relative to the end portion of the bar device and is connected in entraining fashion to the bar device. The carrier rod carries an upper magnet carrier above the coil and a lower magnet carrier below the coil. Fixed to the magnet carriers are rigid permanent magnets of which one pole points axially in the same direction. The travel of the carrier rod amounts to a few millimeters.

Abstract: As a function of the occurrence of first square-wave signals the circuit arrangement generates a time window and monitors the appearance of second square-wave signals during the time span defined by the time window. If the second square-wave signals appear during the time window, appropriate output signals are generated. The circuit arrangement contains an integrator which is reset by the first square-wave signals and released subsequently. A comparator compares the voltage at the integrator with two threshold values. If the first threshold valve is exceeded, the time window is opened, and it is reclosed if the second threshold value is exceeded. The threshold values are generated by means of a switchable voltage divider. This voltage divider is switched by means of a flip-flop if the voltage at the integrator exceeds the first or second threshold value, respectively.

Abstract: For suppressing faults in binary data signals, two circuit branches respectively allocated to one of the polarities of the data signals and each comprising an integrator element and a comparator are provided. The integrator elements, triggered by an edge change of the data signals into the allocated polarity, regardless of a following edge change, acquire the signal components of this polarity up to a prescribed threshold. In response to a corresponding output signal of the following comparator, both integration elements are reset in common. The comparator output signals are also supplied to the set or reset inputs of a bistable switch means which outputs the noise-deinfested data signals.
