摘要:
A circuit for analogously controlling a capacitive charge, has a drive source used to provide an operating voltage or an operating flow used to charge the capacitive charge, a circuit arrangement used to charge and discharge the charge, and a storage capacity used to intermediately store the charge of the charge during the discharge of the charge and to emit intermediately stored charge to the charge during charging of the charge. In a method for analogously controlling a capacitive charge by applying a operational voltage or an operating flow of a drive source in order to charge the capacitive charge onto the charge and to discharge the charge, during a first discharge phase, the charge of the charge is intermediately stored in a storage capacity and during a first charging phase, which is used to charge the charge, the charge from the charge capacity is charged in the charge.

Described are recombinant DNA molecules comprising the regulatory sequence(s) of an intron of the Endothelial Growth Factor (VEGF) receptor-2 gene (Flk-1) or of a gene homologous to the Flk-1 gene, being capable of conferring expression of a heterologous DNA sequence in endothelial cells, preferably in vivo. Vectors comprising said DNA molecules as well as host cells containing the same are provided. Also provided are pharmaceutical and diagnostic compositions comprising such recombinant DNA molecules and vectors. Furthermore, cells and transgenic non-human animals, comprising the aforementioned recombinant DNA molecules or vectors stably integrated into their genome and their use for the identification of substances capable of suppressing or activating transcription of a gene in endothelial cells are described. Described is further the use of the before described recombinant DNA molecules and vectors for the preparation of pharmaceutical compositions for treating, preventing, and/or delaying a vascular or tumorous disease in a subject. Furthermore, uses of the recombinant DNA molecules and vectors of the invention for the preparation of pharmaceutical compositions for inducing a vascular or tumorous disease in a non-human animal are provided.
摘要:
The injector tip of an injection valve which injects directly into the combustion chamber protrudes therein, thereby incurring the risk that combustion residues can become deposited on the injector tip. When the injection valve is in a closed state, the possible attachments of combustion residues along a separation line (10) are eliminated by means of a special configuration of the surface at the separation line (10) between the valve body and a valve plate. The surface is represented in a smooth, step-less, edge-less and curved manner.

An injection valve for injecting fuel comprises a valve housing (1) inside of which a drive unit (15) controls the movement of a valve needle (5) that is pretensioned by a spring (11). The injection valve also comprises a main chamber (27), which is provided inside the valve housing, is filled with fuel and accommodates the valve needle (5), and comprises a hydraulic bearing for the drive unit (15). The hydraulic bearing has a hydraulic chamber (29) that is connected to the main chamber (27), whereby fuel serves as the operating substance of the hydraulic bearing.
摘要:
A wobble motor has at least one shaft guided in a rotatably and axially displaceable fashion, and at least one drive ring which surrounds the shaft and can be tilted with respect to a longitudinal axis of the shaft. The at least one guide ring can be displaced in a frictionally locked fashion and free from rotation.

A wall-controllable primary drive, for example a piezo actuator, guided in a first bore transfers its stroke motion-commutated onto a secondary-side lifter element guided in a second bore, transmitting said stroke by a piston-hydraulic stroke transmission on the basis of a hydraulic chamber. The pressure in a valve chamber is controlled via secondary-side lifter element.
摘要:
A device is provided which allows exact apportioning and controllable atomization of fuel as necessary for various operating conditions of an internal combustion engine. The apportioning ensues with an apportioning aperture that can be closed via a valve needle. Separately therefrom, the atomization ensues with a piezoelectrically driven nozzle having an atomizer orifice placed into vibration. The shape of the atomizer aperture can be round, triangular, quadrangular or cross-like.
摘要:
A substantially uniform and nevertheless low feed line resistance of the conductor paths (L.sub.i) can be realized for all heating elements in an ink jet printer by a suitable dimensioning of a transition structure (UV) of a conductor path layout disposed on a thin-film substrate. This transition structure connects the conductor paths of close spacing (LA) in the region of the heating elements (RH) to the conductor paths of wide spacing (LB) in the region of the bonding contacts to each other. For this purpose a dimensioning requirement is required, which in case of predetermined input values, i.e. the conductor path widths (d.sub.a, d.sub.b) and the separation distance widths (s.sub.a, s.sub.b) furnishes in the two regions and in the separation distance width (s.sub.v) of the transition structure (UV) as starting value the conductor width (d.sub.v) in the transition structure (UV).
