A microlens array having first and second sets of spherically-shaped microlenses. The incoming conveyor is disposed for the feeding of timber pieces. The apparatus further includes a novel fluid flow control assembly that precisely controls the flow of the medicament solutions from the apparatus reservoir to the patient. An input interconnection includes an upper input interconnection formed on the upper surface of the film substrate and a lower input interconnection formed on the lower surface and extending away from the bending part. A separate thermostat may be operatively attached to each vortex tube and extend outwardly from the cabinet to be positioned within the interior of the enclosure. A gas having a lower ionization energy than nitrogen, such as for example, helium, may be used in combination with nitrogen to produce a lower power plasma resulting in a steeper concentration curve for nitrogen in the silicon oxide film.
