...battery's strength (one millionth of a watt) is hardly one fly-power, and ninety-nine percent of the energy from the Strontium 90 is still wasted. But the battery is strong enough to work a transistor. RCA believes that its strength can be increased enough to make the battery useful. The Strontium 90 is durable; it loses only half of its power in 20 years...
...Drilled Transistor. The big trouble with transistors is that they are hard to mass-produce with sufficient accuracy. The tiny specks of germanium that are their essential parts must be made with extreme precision. Even with the best of workmanship, many finished transistors have to be rejected...
...liquid slowly dissolves the germanium. When they have almost drilled through the slab, leaving only a few ten-thousandths of an inch, the current is quickly reversed. The drilling stops, and the reversed current deposits metallic indium on both sides of the thin germanium wafer. The result is a transistor with two indium electrodes to which wires can be attached...
Tiny Titan. The first commercial transistor powerful enough to replace vacuum tubes in control devices for industrial machines was announced by Minneapolis-Honeywell Regulator Co. The size of a thimble, it is 100 times more powerful than any transistor yet available, said Honeywell, can handle 20 watts of current...
...Sister Transistor. General Electric announced a tiny electronic capacitor that is designed to work as a companion to the transistor. About as big as a kernel of corn (and about a quarter the size of the smallest capacitor G.E. has turned out so far). the new capacitor can store energy and release it later when needed. Made mostly of silver and tantalum, it filters electric current, eliminating interference and improving the tone of such devices as miniature radios and hearing aids. Price: about...
