Title: Circuit arrangement for driving two I<2>L gates via a single control terminal
Inventor: EBERHARDT KURT DIPL ING
IPC: H03K17/60
Filed: 1982-05-19
Abstract: To drive two I<2>L gates (6, 7), a single control terminal (E) is provided via which the two gates can be separately driven with the logic states: control terminal at operating potential, control terminal at reference voltage, control terminal open. For this purpose, the control terminal (E) is connected, on the one hand, to the tap of a voltage divider (R1, R2) connected between a line (a) carrying the operating voltage and a line (b) connected to reference potential and, on the other hand, to the collector of a dual-collector PNP transistor (1) and via a resistor (R3) to the first collector (C21) of a dual-collector NPN transistor (2). When the control terminal (E) is open, no control currents (I1, I2) flow via the second collectors (C12 and C22, respectively). When the control terminal (E) is connected to the operating voltage (K1), the collector current of the dual-collector PNP transistor (1) is transferred to its second collector (C12). If, in contrast, the control terminal (E) is connected to reference potential (K0), a control current (I2) flows in the second collector (C22) of the dual-collector NPN transistor (2). The circuit operates advantageously above operating voltages of 0.7 V. <IMAGE>

Title: Method for the performance of tests on modifiable memories and control thereof in data and telecommunication systems, in particular telephone systems
Inventor: BLONDEL ERIK
IPC: H04M3/24
Filed: 1982-09-28
Abstract: In order to perform a test on a modifiable memory RAM, memory lines are combined to form a group for subsequent checking, their number being equal to the maximum number of different identifiers which can be represented in one byte. By means of a counting generator with a number supply, for example from 1 to 256, and by means of an address memory, all lines are controlled individually in succession and consecutive numerical values from the number supply are stored, where the numerical values correspond to the line addresses. Errors can easily be detected by comparing the numerical values read out with those newly generated by the counting generator. Similarly, a plurality of lines can be collectively checked in each case for the presence of at least one error. Any errors occurring in the individual memory lines are identified by checking different memory line groups.

Title: Device for notching cylindrical workpieces
Inventor: WEISS JOHANNES
IPC: B21H7/18
Filed: 1983-05-16
Abstract: The invention relates to a device for notching cylindrical workpieces and can be used for the production in large numbers of notched standard parts without a stepped diameter, such as, for example, grooved pins. The aim of the invention is to create a device which achieves the complete processing, particularly of grooved pins, i.e. cutting-off from the starting material and notching, on one machine. The solution according to the invention consists in the creation of a notching device. To produce the notches, notching rollers with a wedge-shaped profile are arranged around the cross-section of the workpiece, the rollers being advanced towards the workpiece in the manner of a crank via their mounting and making a rolled impression in the latter. Each notching roller is mounted on a coupling disc which connects the two-part bearing shaft positively in the manner of an Oldham coupling. The bearing shafts can be adjusted axially parallel to one another to achieve an alteration in the diameter of the circular translation of the mounting of the notching rollers, it thereby being possible to produce different notch shapes. <IMAGE>

Title: Three-dimensional MOS invertor arrangement of integrated semiconductor circuits and method of fabricating it
Inventor: PEISL MARTIN DIPL ING
IPC: H01L27/06
Filed: 1983-06-14
Abstract: This arrangement comprises a silicon substrate (1) in which the source/drain zones (5) of the first transistor have been produced, and a gate electrode (4) which is isolated from the substrate surface (1) by a first insulation layer (3) and which is formed from a first doped polysilicon layer and is also at the same time the gate electrode of the second transistor (28) which is of opposite conduction type and is produced on top of the first transistor in a second polysilicon layer (8). To reduce the overlap capacitances and, consequently, to increase the switching speed in this arrangement, the insulation layer (6, 16, 7, 17) situated between the first (4) and second (8) polysilicon layers is formed in such a way that it has a lower thickness in the region above the gate electrode (4) than in the regions beneath the source/drain zones (5) of the second transistor. In a special embodiment, "oxide spacers" are used. The arrangement is used to produce logic and memory chips having very high integration density and three-dimensional integration for fast applications. <IMAGE>
