Said location device includes a therapeutic image means, a holding means for holding the patient, and a displacing means for the spatially relatively displacement between the holding means and the wave source; in front of the emitter place of the high-power focusing ultrasonic source, there are ...
It could be noted that the advantages of diffractive plate-type emitters are: the possibility of forming ultrasonic vibrations of high power and provide frequency tuning of the radiation due to transition from one harmonic to another. The same diffractive plate-type emitter can create vibrations of...

Transistors have several different variations but the most common is the bipolar transistor, which consists of three pins - the base, the collector and the emitter. Capacitors Capacitors are the second most common component after resistors. Capacitors hold electrical charge within the board and ...
SWIR PAM was first developed for imaging lipids based on the 2nd overtone of the C-H bond14 and more recently imaging water at 1930 nm17, whereas the sensitivity is heavily reliant on the quality of the ultrasonic transducer employed18. Here, we introduce a technique named overtone ...

Whereas the passive grid collected virtually none of the fog from an ultrasonic fog maker, with 35 kV applied the difference was night and day. No water was collected with the first test, but with power applied a significant 40 mL was collected in 5 minutes on the small mesh. With this ...

fine electrode structure to a corresponding fine structure on the heat sink. Moreover, even if alignment were possible, the emitter and base electrodes are so closely spaced, i.e., on the order of 0.1 mil, that conventional bonding techniques, such as soldering or ultrasonic bonding, would ...
Additionally, it has been found that although a fast switching power transistor may have either (1 ) a diffused basic collector region, a base region diffused into the basic collector region, and an emitter diffused into the base region, or (2 ) an epitaxially grown basic collector region, ...
