摘要： A d.c. signal controlled oscillator includes a frequency-determining network having a control input and a modulation input. A phase regulating loop includes the oscillator and components that provide a control signal to the control input. A circuit apparatus for driving the oscillator includes a modulation generator that provides a modulation signal to the modulation input, and a circuit arrangement that autonomously generates a signal depending on and representing a slope of the modulation and provides this slope signal to the modulation generator, which generates the modulation signal dependent on the slope signal. A method of operating the oscillator involves switching a frequency divider successively to two different frequencies, respectively sampling and holding the two different arising control voltages, forming a difference between the two control voltages, and activating the modulation generator so that a modulation swing of the modulation signal is determined by this difference between the control voltages.

摘要： A control unit and two negative feedback branches limit the amplitudes of the output signal of an inverting differential amplifier. Each feedback branch includes a threshold value switch including a transistor as well as an adjustable current source and a resistor forming a voltage divider between a supply voltage and the amplifier output. The voltage divider output is connected to the transistor's base. The transistor selectively connects or disconnects the input of the amplifier with either the supply voltage or the amplifier output. The control unit controls the two current sources based on external programming commands, to establish two adjustable threshold values within which the negative and positive amplitudes of the output signal are limited, symmetrically or independently, in a hard or soft clipping manner. Even with small supply voltages, the limited output will not overdrive subsequent amplifier input stages and will not superimpose harmonics on the useful signal.

摘要： The object of the invention is to create high-tensile molded bodies that are made of titanium alloys and are malleable at room temperature and that, compared with the metallic glasses, have macroscopic plasticity and work hardening, without other properties, such as breaking resistance, elastic elongation or corrosion behavior being thus greatly impaired. The molded bodies according to the invention are characterized in that they are made of a material that in its composition conforms to the formula Tia E1b E2c E3d E4e, where E1 comprises one or more elements of the group containing the elements Ta, Nb, Mo, Cr, W, Zr, V, Hf and Y, E2 comprises one or more elements of the group containing the elements Cu, Au, Ag, Pd and Pt, E3 comprises one or more elements of the group containing the elements Ni, Co, Fe, Zn, Mn and E4 comprises one or more elements of the group containing the elements Sn, Al, Ga, Si, P, C, B, Pb and Sb, where a=100−(b+c+d+e), b=0 to 20, c=5 to 30, d=5 to 30, e=1 to 15 (a, b, c, d, e in atomic %). The molded bodies have a homogenous microstructure, mainly comprising a glassy or nanocrystalline matrix with ductile dendritic body-centered cubic phase embedded therein. A third phase with low volumetric proportion can be present. Such molded bodies can be used as high-stress components, e.g., in the aircraft industry, space aviation and the automobile industry, but also for medical technical equipment and implants in the medical field.

摘要： Disclosed is a method for improving the plastic ductility of high-strength molded bodies from bulk metallic glasses from Zr, Ti and Hf base alloys and molded bodies so produced. An object is to find ways to substantially increase the plasticity and toughness of bulk metallic glasses produced on the basis of early transition metals (Zr, Ti, Hf) which is comparatively low as compared to their very high strength, thereby further increasing their potential applicability as materials for airplane structures. Hydrogen in defined ranges of concentration is introduced into the molded bodies in a concentration below the brittle hydride formation concentration. The molded bodies produced comprise hydrogen in a homogenous distribution in the amorphous short-range order structure and/or in the form of hydrogen-induced local enrichment of ductile alloy components and/or in the form of hydrogen-induced precipitations of ductile nanocrystalline phases while excluding brittle hydrides.
