Abstract: The present invention relates to an automated guide vehicle (10) for transporting objects (38) comprising a support structure (12) with an outer contour (14), a chassis (16) fastened to the support structure (12) having at least one first wheel (18) and one second wheel (20), wherein the first wheel (18) and the second wheel (20) are respectively rotatably mounted in the chassis (16) about a first axis of rotation (D1) and a second axis of rotation (D2), a drive unit (22), with which the first wheel (18) and the second wheel (20) can be driven independently from one another, a lifting mechanism (32) cooperating with the support structure (12) for lifting and lowering at least one support portion (39) which cooperates therewith to transport the objects, and a store (70) for electrical energy, which in plan view protrudes in portions beyond the outer contour (14) of the support structure (12), wherein the energy store (70) is movably fastened to the support structure (12).

Abstract: A semiconductor device includes a semiconductor substrate, a TiW layer arranged on the semiconductor substrate a Ti layer arranged on the TiW layer, a Ni alloy layer arranged on the Ti layer, and an Ag layer arranged on the Ni alloy layer, wherein the Ag layer and the Ni alloy layer comprise side faces fabricated by at least one wet etching process, and wherein the Ti layer and the TiW layer comprise side faces fabricated by a dry etching process.

Abstract: An electromagnetically operated valve, comprises a valve slide with a magnet armature, which is equipped to close a sealing seat in a fluid channel of the valve with a first axial end in a closed position, as well as a sealing element with folded bellows situated between the sealing seat and the first axial end of the valve slide and separates the valve slide from the fluid channel with a fluid-tight seal. The magnet armature is supported in the valve in an essentially non-contact manner due to the fact that the valve slide has a guide pin protruding in the axial direction from the magnetic armature on a second axial end opposite the first axial end, the guide pin being supported to slide in the axial direction; and the valve slide is aligned in the radial direction on a side of the magnet armature facing the first axial end of the valve slide and is supported so it is movable in the axial direction by means of at least one spring element.

Abstract: A drive apparatus has at least two electric motors. There is also a central control common to all motors which lie in series in a closed-circuit energy supply. Each motor has an individual control unit which can be turned on and off from the central control via a control line by an address. Each motor also contains a short-circuit device lying in parallel with its connecting terminals.

Abstract: The present invention relates to an apparatus for producing a succession of pulses corresponding to the succession of pulse beats of a person. The apparatus has a pulse detector and at least one stage subsequent to the pulse detector to suppress disruptive influences. The invention is characterized by a voltage-controlled pulse generator which is controlled by a comparator. The comparator compares the contents of two memories of which the first stores the pulse coming from the pulse detector and the second stores the pulse appearing at the output of the pulse generator.
