โœฆ Synopsis


LIBRARY NOTES.

8 5 electrostatics, dielectric heating, induction heating, ultrasonics, and electronic viewers and phototubes. Then follow chapters on the use of electronics in particular media--in the air, on water, on land and underground. Specific functions that electronics may perform are also considered, such as inspection, production control, measuring, and counting. The many uses of electronics range from those with which the average individual may come in contact, such as traffic controls, diathermy equipment, or safety devices on machinery, to the unusual application seen only by a few--a device for tracking schools of fish. Directly or indirectly nearly all the uses detailed in this book contribute in some way to increased efficiency or heightened production. Electronics has also made possible the accomplishment of many tasks hitherto thought impossible.
