In this work, we discussed the principle of microwave heating. We have come to know how to make the microwave in the microwave oven, and how much thermal energy can be absorbed. We explained the process of microwave ovens making foods with maxwells equation. Now, we can come to calculate the 12/16/2004 5:04:21 PM

Fig. 1. (a) Principle set-up of a piston type micropump. (b) Schematic set-up of the saliva dispensing micropump of Graphosoma lineatum. 2. Early research on reciprocating micropumps Instead of using passive valves the ﬁrst technical micro-pump designs were based on an actuation of both, the pump diaphragm and the valves.

A regenerative heat exchanger, or more commonly a regenerator, is a type of heat exchanger where heat from the hot fluid is intermittently stored in a thermal storage medium before it is transferred to the cold fluid. To accomplish this the hot fluid is brought into contact with the heat storage medium, then the fluid is displaced with the cold fluid, which absorbs the heat.
disk driver board and a plastic housing for the nebu-lizer. The housing has a liquid reservoir and a piezo mesh element. One of the challenges of designing a vibrating mesh nebulizer is to generate an adequate and reliable ana-log driving signal, as required to drive a corresponding piezo mesh disk. The piezo mesh disk requires a high
