Synchronous advantage

Another possible advantage of the PHB method is its potential multiplexing characteristics by synchronous recording and read-out, exceptional data transfer rates can be achieved. These high transfer rates are of equal importance in practical data technology as high storage densities. 

A rule of thumb that was used in the past for constant speed applications wii.s to consider the selection of a synchronous motor where the application horsepower was larger than the speed. This, of course, was only an approximation and tended to favor the selection of a synchronous motor and would be considered too severe by current standards. However, the rule can aid in the selection of the motor type by giving some insight as to when the synchronous might be chosen. For example, applications ol several hp per rpm often offer a distinct advantage of the synchronous over the induction motor. In fact, at the lowest speeds, larger sizes and highest hp/rpm ratios may be the only choice. 

Important advantages of direct-current motors for machine drives are the adjustable speed over a wide range, the fact that speeds are not limited to synchronous speeds, and the variation of speed-torque characteristics [8]. 

Another milder example of this is a standard Non-Synchronous Buck switcher IC. Every single typical applications diagram on the datasheet shows a Schottky diode, without perhaps explicitly stating as much. This is an example of an implied expectation on the part of the vendor—that you, the customer, won t miss the truly obvious. Yet there are many who think they have achieved some slender advantage in substituting an ultra-fast diode in its place. First read the Abs Max section of the EC tables carefully. Most vendors specify that the SW node should never be taken more than 0.4V below IC ground. That is because... 

It is apparent there is a definite advantage to operating under solvent-free conditions. The specific microwave effect is here of low magnitude, but evident, because after 3 min the yield increases from 64 to 98%. Prolongation of the reaction time with classical heating led to an equivalent result. The microwave effect is rather limited here, because of a near-synchronous mechanism. 

Formation of 2//-azirines by thermal decomposition of vinyl azides has been shown to exhibit small entropy of activation and insensitivity to solvent polarity acyclic vinyl azides decompose more readily than analogous cyclic ones and it is advantageous to have a hydrogen atom cis to the azido group ( -are more reactive than Z-isomers). These results and the linear correlation found for ring-substiment effects on decomposition of a-styryl azides are consistent with a nonconcerted mechanism in which elimination of nitrogen and cyclization into a three-membered ring proceeds synchronously. 

One advantage of this method is the automatic synchronization of both pulses to within a few nanoseconds. The second pulse can easily be delayed by changing the length of the light path before generating the microplasma.
