Abstract: The cantilever of a probe-based metrology instrument such as an AFM is deflected by directing a beam of ultrasonic energy at the cantilever to apply ultrasonically generated acoustic radiation pressure to the cantilever. The energy is generated by an ultrasonic actuator such as a ZnO transducer driven by a power source such an RF signal generator. The transmitted beam preferably is shaped by focusing, collimation, or the like so that it impinges at least primarily on a region of interest of the cantilever such as the free end. The ultrasonic actuator produces a much better controlled force on the cantilever than can be achieved through the use of a traditional piezoelectric actuator and, accordingly, produces a response free of spurious effects (at least when the cantilever is operating in liquid). It also has a frequency bandwidth in the MHz range.

Abstract: The oscillation frequency of a fluid jet in a fluidic oscillator is measured using a temperature sensor. The resistance of the temperature sensor varies as a function of the oscillation of frequency f0 of the jet. The method consists in feeding the temperature sensor with an AC voltage of frequency f, and then in determining the frequency components around the frequency 3×f in the output signal from the temperature sensor in order to determine the oscillation frequency f0 of the jet. The frequency components in the signal output by the temperature sensor are determined by measuring the measurement signal across the terminals of the temperature sensor, then by synchronously demodulating the measurement signal at the frequency 3×f, and finally by determining the frequency of the demodulated measurement signal, which frequency corresponds to the oscillation frequency f0 of the jet.

Abstract: Upon a drop in engine rotation speed, a direct current voltage which periodically changes is applied to coils of pole magnets 18u-18w, thereby causing an increase or reduction in the rotation speed of the second flywheel 21.

Thereby, the shock which is produced upon connection of a second flywheel is reduced, and slippage occurring during connection of a second flywheel is also reduced.

Abstract: A method and apparatus for increasing hydrocarbons to a direct reduction shaft furnace while controlling the temperature uniformity of the center portion of the iron burden wherein the hydrocarbon gases used in direct reduction may be preheated, which increases the temperature of the hydrocarbon gases, and therefore increases the resultant temperature of the upflowing gases as it rises from the lower section of the furnace into the center of the burden. Alternatively, a portion of the upflowing gas may be removed before it enters the reduction zone of the furnace. The removed upflowing gas, known as hot bleed gas, may be ducted to the top gas scrubber of the furnace or may be mixed with the main reducing gas stream of the furnace for reintroduction to the furnace. Alternatively, hot reducing gas may be directly injected into the center portion of the burden, offsetting the cooling effect of the upflowing gas.
