Abstract: The invention relates to a clamp-shaped sheet metal nut for automatic assembly on a carrier plate. The sheet metal nut in this case consists of a threaded limb (1), having an impressed thread (4), and a clamp limb (2), connected thereto via a lateral web (3), which is provided with a screw penetrating hole (5), both limbs running inclined with respect to one another in the direction of their free ends and the free end of the threaded limb (1) having an insertion plate (6) projecting away obliquely from the clamp limb (2). 
<??>In order to be able to place the sheet metal nut automatically by means of a correspondingly designed assembly device even on attachment points where access is difficult, that is to say to be able to push it onto the edge of the carrier plate, outwardly projecting guide wings (12) are integrally formed laterally on one of the two limbs (1 or 2), on which guide wings the sheet metal nut is held in the retaining head of the assembly device while being pushed on.

Abstract: The invention relates to a static memory having a plurality of hierarchical levels (H0...H3). Good ways of accomplishing this are specified here, since the area requirement for the driving and reading circuits on the second hierarchical level (H1) is particularly critical. Memory cells which produce a strong cell signal, so that the read circuit is uncomplicated, are advantageously used for this. By relocating peripheral circuits to higher hierarchical levels, a reduced access time and a reduced area requirement are obtained. <IMAGE>

Abstract: In a test of a fabricated semiconductor memory chip, a test control signal is supplied to a test control circuit, so that a spare memory cell array is tested whether spare memory cells are functionable for writing and reading of data. The test control signal is applied to terminals which are used for the supplying of an address signal, etc. For this purpose, the test control signal has a level different from that of the address signal. Therefore, the spare memory cell array can be tested simultaneously with a test of normal memory cell array.

Abstract: A regulated switch mode DC-DC converter comprises a logic gate package connected to a DC power supply and providing four NOR logic gates. Two of the NOR gates are connected for providing an oscillator circuit producing one or more AC outputs which are applied to the inputs of the other respective NOR gates which act as driver gates for power transistor means. The power transistor means conducts intermittently in order to provide from a DC power supply a regulated current which may be fed to the primary of a de-coupling or isolating transformer the secondary of which feeds a rectifier circuit which provides a DC regulated output. The ON/OFF periods of the power transistor means are controlled by control means in order to provide the requisite regulation of the DC output of the converter.

Abstract: In a semiconductor device, an inter-level insulating film (3) is formed at solid crossing points between upper level interconnections (6) and lower-level interconnections (2), excepting via hole portions. This means that mechanical support between interconnection levels is given by solid crossing points between interconnections. For this, a semiconductor device having high durabilities against thermal and mechanical impacts can be obtained. 
     Further, since inter-level regions other than the solid crossing points are made vacant to form a cavity, coupling capacity can be reduced to 1/3 to 1/2 of an ordinary multilevel interconnections wherein inter-level regions are fully filled with an inter-level insulating film.

Abstract: A method of providing an appropriate strobe pulse width for a print head element in a thermal printer wherein a look-up table is created for determining target strobe pulse durations. These durations are computed functions of power supply voltage levels, measured in real time, print head element temperatures, measured previously, and average element resistance, also measured previously. Once such a table is established, strobe pulses are initiated for driving current through print head dot elements. Periodically the power supply voltage levels in the print head are measured and the values temporarily stored. The look-up table is consulted to obtain a target strobe pulse width which is compared to the elapsed time of the strobe. The strobe pulse is continued so long as the latest target pulse width exceeds the width or elapsed time of the strobe pulse. The strobe pulse is terminated when the latest target pulse width has been equaled or exceeded by the elapsed time of the strobe pulse.

Abstract: The disclosure relates to a radar apparatus of the type which comprises a transmitter which substantially continuously transmits a modulated carrier wave signal, and a receiver for receiving the carrier wave signal (the echo signal) reflected against an object, and in which the carrier wave signal is modulated with an encoding signal in which one bit in the code is of a duration which is several times longer than the period time of the carrier wave signal, and in which the code of several bits forms a block which is characterized by modulation of a carrier wave at constant frequency. Furthermore, the frequency of the carrier wave is changed between the blocks, so that the transmitter transmits one block with a carrier wave frequency which is different from the carrier wave frequency or frequencies which the receiver is set to receive. The apparatus includes means for dividing code blocks of the same frequency into a number of subunits, for example eight in number, in which each subunit is first correlated individually, and thereafter doppler analysis is carried out on the subunits of the block.

Abstract: A non-destructive method of determining the amount of deformation induced in a material by a compressive force comprises the steps of uniformly dispersing a quantity of a particulate tagging substance in the material whose presence and distribution is detectable by a form of radiant energy, applying a compressive force to the material, and then determining the extent to which the material is compressively deformed by transmitting the appropriate radiant energy through the material to determine changes in the density and distribution of the particulate tagging substance. The method may advantageously be applied to determine the extent to which a granular material such as asphalt concrete has been compacted over a roadbed, as well as to determine strain and wear patterns in gaskets formed from elastic materials.

Abstract: In a TDMA cellular mobile communication system, a mobile station receives a TDM signal from a cell site and detects a signal indicating the propagation delay time of signals between the cell site and the mobile station. From an assigned timeslot, a time interval from a detected frame sync to the time of transmission of a burst signal from the mobile station is determined. The propagation delay time indicated by the detected signal is subtracted from the determined time interval. When a frame sync is detected from the received TDM signal, clock pulses are counted until it corresponds to the subtracted time interval, whereupon a timing pulse is generated to cause a burst signal to be transmitted from the mobile station to the cell site.
