...transistor was developed only eight years ago by three scientists at Bell Telephone Laboratories. It amplifies electrical impulses just like the vacuum tube, but is free of the vacuum tube's limitations-fragility, bulkiness, high power consumption, short life. The transistor needs no warmup time, saves space, weight, heat and power, lasts 150 times as long, uses as little as one-thousandth the electric current...
...Today 99% of hearing aids are transistorized; Zenith has a model selling for $50. As transistor production climbed from 100,000 in 1952 to a rate last week of 9,000,000 a year, the price dropped to about $2 apiece. Though they are still more expensive than most vacuum tubes, transistors are nevertheless conquering market after market...
Wrong Approach. In Denver, Hotel Desk Clerk Mrs. Burnace Hadley, 49, hit an armed robber on the head with a nightstick, made a direct hit on him with a vacuum bottle as he stepped back, rapped him on the fingers with the club when he made a last grab for the hotel's money, explained to police after he fled: "He made me mad with his brashness...
Just before they come to a focus, the rays enter a vacuum chamber through a sheet of salt (transparent to infrared) and form their image on the blackened surface of a thin sheet of plastic. The other side of the plastic is covered with a film of silicone...
...nuclear reactors, for instance, can turn into radioactive junk in a fraction of a second. To avoid such misadventures, most modern mechanical and electronic systems are equipped with built-in monitors that watch their operation and shut them down promptly at the first sign of trouble. But if a vacuum tube or relay in the monitor fails, the main machine is like a building whose night watchman has dropped dead. Trouble can start and get out of hand with no one to correct it or give the alarm...
