摘要:
A brewing unit (1) of an espresso coffee machine including a brewing chamber (25) and at least one spring-loaded pressure valve (16) which is flow-technically arranged between the brewing chamber (25) and a coffee beverage outlet and which opens when the brewing chamber pressure exceeds a structurally predetermined value. In order to produce by means of the coffee machine one kind of coffee beverage selected from at least two kinds of coffee beverages, an atmospheric coffee beverage bypass channel (21) flow-wisely disposed in parallel relative to the pressure valve (16) between the brewing chamber (25) and the coffee beverage outlet (23) may be locked depending on the kind of coffee beverage selected.

Method for monitoring the state of a tire, in which at least one analysis value (UR i), from which the state of a tire is determined, is formed from wheel speed signals (ωrot i) of the vehicle wheels, wherein the analysis value (UR i) is an absolute rolling circumference of a tire or a variable which represents the absolute rolling circumference of a tire, in particular a dynamic tire radius which is determined by evaluating wheel speed signals (ωrot i) and signals from at least one sensor in order to measure the speed of the vehicle over an underlying surface, and the analysis value (UR i) is used to determine a loss of pressure and/or working loads of the tire, as well as a device for monitoring the state of the tire.

In a method and an associated device for generation of digital x-ray image exposures of an examination subject with an x-ray source and a digital x-ray detector for a stereotactic biopsy, wherein, for one or more x-ray image acquisitions of the examination subject with a biopsy device, acquisition and image processing parameters are used that have been determined from an x-ray image exposure of the examination subject without the biopsy device (7). The influences that are disruptive for an optimal x-ray image, for example of metallic biopsy devices, can thereby be avoided.
摘要:
During the patterning of via openings in sophisticated metallization systems of semiconductor devices, the opening may extend through a conductive cap layer and an appropriate ion bombardment may be established to redistribute material of the underlying metal region to exposed sidewall portions of the conductive cap layer, thereby establishing a protective material. Consequently, in a subsequent wet chemical etch process, the probability for undue material removal of the conductive cap layer may be greatly reduced.

An elevator installation and a method for arranging a load sensor in the elevator installation includes a car, a support device for supporting the car, the load sensor and a deflecting roller unit. The deflecting roller unit is arranged at the car and has at least two deflecting rollers which are rotatable about a common axle. The load sensor is arranged on the common axle between the two deflecting rollers.
摘要:
When forming sophisticated metallization systems, surface integrity of an exposed metal surface, such as a copper-containing surface, may be enhanced by exposing the surface to a vapor of a passivation agent. Due to the corresponding interaction with the metal surface, enhanced integrity may be accomplished, while at the same time damage of exposed dielectric surface portions may be significantly reduced compared to conventional aggressive wet chemical cleaning processes that are typically used in conventional patterning regimes.

In a method and a medical installation for assisting in a medical measure implemented by a medical device, a lighting element generates light that uniformly illuminates the medical device or its environment, the illumination being designed to reduce stress on the part of a patient undergoing the medical measure.
摘要:
By using powerful data analysis techniques, such as PCR, PLS, CLS and the like, in combination with measurement techniques providing structural information, gradually varying material characteristics may be determined during semiconductor fabrication, thereby also enabling the monitoring of complex manufacturing sequences. For instance, the material characteristics of sensitive dielectric materials, such as ULK material, may be detected, for instance with respect to an extension of a damage zone, in order to monitor the quality of metallization systems of sophisticated semiconductor devices. The inline measurement data may be obtained on the basis of infrared spectroscopy, for instance using FTIR and the like, which may even allow directly obtaining the measurement data at process chambers, substantially without affecting the overall process throughput.
摘要:
A self-centering brake for a lift provides for the same braking moment in the case of normal operation and in the case of failure of a brake half. The brake consists of a housing which is U-shaped in cross-section, wherein a limb of the U corresponds with a brake half. The brake halves are of identical construction. An active brake lining and a passive brake lining are provided for each brake half. The active brake lining is loaded by a spring force of a compression spring. In the case of failure of a brake half the passive brake lining takes over the function of the active brake lining.
