    摘要: An apparatus for ascertaining, and/or monitoring, volume- or mass-flow of a medium flowing through a pipeline in the direction of the longitudinal axis of the pipeline. The apparatus includes: at least one ultrasonic sensor, which radiates/receives ultrasonic measuring signals at an angle of incidence/emergence into/out-of the pipeline; and a control/evaluation unit which provides, based on the ultrasonic measuring signals, information concerning volume- and/or mass-flow of the medium through the pipeline. The ultrasonic sensor includes at least one sound-producing element, a coupling shoe and a coupling adapter. The end region of the coupling adapter facing the coupling shoe has a securement mechanism for releasable securement of the coupling adapter to the coupling shoe. The end region of the coupling adapter facing the pipeline is embodied as a function of the pipeline in such a manner that it is form-fittingly securable to the pipeline.

    摘要: An ultrasonic, flow measuring device having a plurality of measuring channels. At least one ultrasonic sensor is situated in a first region of a pipeline, or measuring tube; at least two ultrasonic sensors are situated in a second region of the pipeline (5), or measuring tube, in such a manner that the ultrasonic measuring signals travel through the pipeline, or measuring tube, in, or opposite to, a stream direction of the medium, on sound paths of different lengths. A transmitting stage simultaneously excites the ultrasonic sensor, or the ultrasonic sensors, of the first or second region for transmitting the ultrasonic measuring signals. Due to the different lengths of the sound paths, the receiving stage detects the ultrasonic measuring signals incoming to the ultrasonic sensors of the second or first region at separate times. The evaluating stage ascertains, on the basis of travel-time difference of the ultrasonic measuring signals on the individual sound paths, in, and opposite to, the stream direction, volume- and/or mass-flow of the medium in the pipeline, or measuring tube.

    摘要: A perpendicular magnetic recording media is provided having an imbalanced magnetic moment multilayer cap. The perpendicular magnetic recording media comprises a granular layer, and a multilayer cap structure exchange coupled to the granular layer. The multilayer cap structure includes upper and lower magnetic layers separated by a non-magnetic layer, where the upper magnetic layer has a magnetic moment greater than the lower magnetic layer. When an external field is applied to the recording media, a larger moment torque is triggered at the surface, and more efficient switching is facilitated. The upper magnetic layer may have a higher magnetic moment than the lower magnetic layer if the upper magnetic layer comprises a larger magnetic moment material than the lower magnetic layer. The upper magnetic layer may also have a higher magnetic moment than the lower magnetic layer if the upper magnetic layer has a greater thickness than the lower magnetic layer.

    摘要: A perpendicular magnetic recording medium includes a metamagnetic antiferromagnetically-coupled (AFC) layer between the recording layer (RL) and the soft magnetically permeable underlayer (SUL). The metamagnetic AFC layer has essentially no net magnetic moment in the absence of a magnetic field, but is highly ferromagnetic in the presence of a magnetic field above a threshold field. Thus the metamagnetic AFC layer does not contribute to the readback signal during reading, but channels the write field to the SUL during writing because the threshold field is selected to be below the write field. An exchange-break layer EBL is located between the metamagnetic AFC layer and the RL. The metamagnetic AFC layer contains films with a crystalline structure suitable as a growth template for the EBL and RL, so the metamagnetic AFC layer also functions as part of an “effective EBL”, thereby allowing the actual EBL to be made as thin as possible.
