CAVITY WALLS
INTRODUCTION
The term «cavity wall» is applied to a type of masonry wall construction in which a continuous air space or cavity is provided inside the wall.
A cavity wall therefore is actually two walls separated by an air space, but joined by means of metal ties for structural strength. They are extensively used in European countries, particularly Great Britain, where they have been developed as a means of obtaining protection from penetration of rain through masonry walls.
In recent y ....etc

This inverter is very easy to construct, reliable, and even powerful enough to light up a 15W florescent tube (if you cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It's a miniature high frequency transformer that has a 25mm x 20mm x 5mm ferrite core, 30 turns of primary, 15 turns of feedback, and 250 turns of secondary all concentric, wound on plastic frame than wrapped with a 'yellow' adhesive tape. If you can't find it in your local electronic shops then ....etc

Cavity magnetron


The cavity magnetron is a high-powered vacuum tube that generates
microwaves using the interaction of a stream of electrons with a
magnetic field. The 'resonant' cavity magnetron variant of the earlier
magnetron tube was invented by John Randall and Harry Boot in
1940. The high power of pulses from the cavity magnetron made
centimeter-band radar practical. Shorter wavelength radars allowed
detection of smaller objects. The compact cavity mag ....etc

In an information society, where the primary preoccupation in life is the generation, dissemination and management of information, there is an ever-increasing appetite for computing power and interconnection bandwidth. In the coming era of teraflop computing and multi terabyte storage, multiple processors and large data stores will be interconnected with up to terabit per second aggregate bandwidth over distance extending from just centimeters to hundreds of meters. VCSEL based optical interconnections can meet the speed, distance and density d ....etc

The vertical-cavity surface-emitting laser (VCSEL) is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.There are several advantages to producing VCSELs when compared with the production process of edge-emitting lasers. Edge-emitters cannot be tested until the end of the production process. If the edge-emitter does not work, whether due to ....etc

Vertical Cavity surface Emission Lasers (VCSEL) are lasers that emit light from their surface in contrast with regular ???edge emittersâ„¢. Also they have got a vertical cavity , as the name suggests, which enables surface emission.???Vixels??? , as they are commonly called ,have several superior characteristics compared to their edge emitting counter parts.

VCSEL Semiconductor micro laser diodes which emit light perpendicular to their PN junction in a cylindrical beam vertically from the surface of a fabricated wafer and feature circul ....etc
