Patent DE-3434677-A1 (DE)
Title: Direction-finding arrangement
Inventor: BODEMANN GERHARD DIPL ING
IPC: G01S3/58
Filed: 1984-09-21
Abstract: In a direction-finding arrangement in which the angle of incidence of a wave, the direction of which is to be found, is determined from the phase angle of an audio-frequency amplitude modulation of a radio-frequency voltage relative to a reference signal, several individual antennas are combined in pairs and arranged in such a manner that the lines linking the individual pairs of antennas are differently aligned and uniformly subdivide the angular range to be monitored. From the antenna voltages of the two individual antennas of each pair, a difference voltage and a sum voltage are obtained which are then combined in the same phase in an adding element to form an output voltage. The audio-frequency-amplitude-modulated radio-frequency voltage is produced by cyclically progressively connecting the output voltages of the various antenna pairs to a receiver.

Title: Method for measuring distortion effects in an electro-acoustic transducer, in particular a loudspeaker, headphones or the like
Inventor: HEINEMANN GERHARD DIPL ING
IPC: G01R23/20
Filed: 1984-10-11
Abstract: Method for measuring distortion effects in an electro-acoustic transducer, in particular a loudspeaker, headphones or the like. The transducer is activated sinusoidally by a sine-wave generator. The acoustic signal of the transducer is preferably received by a sound pick-up. A signal impaired by the distortion effect is sampled and subjected to analog/digital conversion and to a digital filtering process. The sum of the harmonics representing the distortion effect is separated from the useful signal without corrupting their phase angles, the curve pattern of the useful signal is compared at specific points with the curve pattern of the signal impaired by the distortion effect and the difference between the compared patterns is assessed as a distortion effect whenever a predefined limit value is exceeded.

Patent DE-3442988-A1 (DE)
Title: Electrically controllable optical directional coupler
Inventor: SCHLAAK HELMUT DIPL ING DR
IPC: G02F1/313
Filed: 1984-11-26
Abstract: The power splitting at the output of an electrically controllable optical directional coupler can be controlled by electrooptical variation of the coupling coefficient. In this case, the coupler can be switched from the crossed state to the parallel state for any desired geometrical lengths. The combination of this novel control effect with the electrooptical detuning of the two waveguides of a directional coupler (which may also have an intrinsic detuning as a result of their dimensioning) allows the modulation characteristic to be optimised. Intensity modulators which can be operated without a bias voltage can be constructed by suitable selection of the geometrical coupler length, of the intrinsic detuning and of the control effect with respect to the coupling coefficient and the waveguide detuning. In order to implement these or other modulation characteristics, stepped control electrodes can also be used whose polarity is alternately reversed and which may also be shaped differently.

Title: Process for fabricating adjustment marks, calibration structures and measuring structures in the sub- mu m region for electron-beam and ion-beam scribing and measuring technology
Inventor: SCHNEIDER-GMELCH BRIGITTE
IPC: G03F9/00
Filed: 1985-01-31
Abstract: For the purpose of fabricating adjustment marks and calibration structures in the sub- mu m region, a material having a high relative atomic mass (>100) in a thin layer (4) is used, which is patterned on an electrically conductive layer of material (3) having a low relative atomic mass (<50) by dry etching by means of a masking layer (5) consisting of an electron beam-sensitive resist. The layer sequence (4, 3) preferably comprises the combination gold and aluminium and is applied to a polyimide or photoresist layer (2). By combining a thin layer (4) which exhibits high electron back-scattering, on substrates (3) which exhibit low back-scattering, marks can be fabricated for electron-beam scribing and measuring technology which have fine structures down to the range of the probe diameter (1/10  mu m) at a signal-to-noise ratio of >2:1. By means of direct ion-beam scribing, the gold layer can alternatively be patterned directly, without the circuitous formation of a resist. <IMAGE>

Patent DE-3543334-A1 (DE)
Inventor: BRUEHMANN WERNER
IPC: F02D23/02
Filed: 1985-12-07
Abstract: A pneumatic diaphragm control element for a fuel injection apparatus for internal combustion engines, in particular for supercharged diesel engines, has a thrust rod that is axially displaceable between two end stop counter to the force of a restoring spring, which thrust rod acts upon a control member of the fuel injection apparatus and is connected to a pressure-actuated diaphragm. One end stop determines the position assumed by the thrust rod when there is no pressure and is embodied as a stop screw for the thrust rod. The second end stop defines the position assumed by the thrust rod with maximal pressure being exerted on the diaphragm, and to this end cooperates with a counterpart stop that is adjustably coupled with the thrust rod. For better adaptation of the regulating characteristic, the counterpart stop is embodied as a pre-stressed spring assembly with two stop positions, such that when the first stop position is attained, after the spring pre-stressing is overcome, a further displacement travel (S2) of the thrust rod until the second stop position is attained is available.
