A Powerful Modular Computer On A Universal Building Module

Abstract

This paper develops basic principles for constructing instruction sets for two modifications of a modular computer distinct from each other in both the width of the primary memory and the increment h in which consecutive computer sizes are formed. It is shown that since modular computers are assembled from universal modules using pin-to-pin connections only, in constructing an instruction set one has to rely on the modular control organization principle which provides selective activation and deactivation of the same logical circuits in different modules without violating the principle of circuit identity. The paper develops new complex instructions which speed up computations.

Regimes of piezoelectric transformer operation II

“…The value of Ku 0 is determined by Q eff0 and k 31 according to equation (3) for this type of PT, as was shown in [1,8]:…”

“…The transformer To facilitate the investigations, a PT with a symmetric and simple structure was chosen (figure 1). This kind of PT can easily be measured and calculations can be performed either using the standard linear model described in [7,8] or, for more detailed information, using some finite element simulation program [1]. The results for this type of transformer can nevertheless later be used for other types of transformers with different geometries and polarizations using 'form factors' added to the calculation of the parameters.…”

“…To investigate the case with load, it is advantageous to transform the output part of the PT into the input part by changing the output capacitance C out to C outT and the load resistance R L to R LT . This was done according to [7][8][9]. Such an equivalent circuit is shown in figure 8.…”

“…If special care is taken to contact the PT body only within small areas around the nodal points, we can neglect R v -the losses from mechanical contacts-as well. As for open and short circuit conditions, the load resistance R LT is 0 and has no influence on the vibration processes in the PT body [1,8,9]. Q eff will be maximal (as R1 is minimal and equal to R m ) and we will name it Q eff0 , as introduced in [1].…”

“…For the regime of maximum power, the efficiency is 50% and R1 is equal to 2R ms as for satisfying the conditions for maximum power transfer from the PT to the load, the electromechanical damping induced by the load R LT is equal to the structural damping R ms (R el being neglected, see equation ( 1)) [7][8][9].…”
