Most Portable Portable. A portable radio-phonograph (8½ in. by 11 in.) was put on sale by the Rockland Precision Manufacturing Co. The transistor set requires only four ordinary flashlight batteries to operate, will play 6,000 records (45 r.p.m.) or 750 hours of radio without a battery change. Price: $79.95 for the set, $49.95 for the phonograph alone...
Jones has worked in both electronics and solid state physics. Senior Engineer at the Shockley Laboratory until recently, he has done research in transistor design, semiconductor crystal technology and paramagnetic and diamagnetic resonance in gas plasmas...
...eyes and ears far into the skies and deep into the ocean. With peace came radar's civilian counterpart : a vast new TV industry that has already put 42 million sets in U.S. homes. But the great breakthrough in electronics came in 1948. Bell Telephone Laboratories discovered the transistor, which took over many of the functions of temperamental glass vacuum tubes. Along with other new semiconductors such as power diodes and capacitors, some as small as a grain of wheat, it opened up a vast new field of miniature components for better machines. Made out of solid materials...
Weak signals (measured in microwatts) from the radio pill's transistor oscillator can be received a few feet away, vary in frequency with changes of pressure on a rubber membrane stretched across one end (e.g., frequency decreases when the pill reaches a churning stomach, rises when it enters a slowly pulsating small intestine). A fluoroscope can keep track of the pill's position in the body, while a receiver picks up the FM signals, presents them to the examiner on an oscilloscope as graph waves. Prospects are good that the transmitter will replace awkward, uncomfortable tubes now used...
...Electric and Radio Corp. of America, Texas Instruments Inc. is a lusty newcomer in the U.S. electronics industry. But it can hold its own in any competition. Launched in electronics at the close of World War II, the Dallas company by 1954 was a major military producer of germanium transistors as tiny substitutes for standard electronic tubes. Soon after, it produced an even better silicon transistor for military use, then swept into civilian markets with its germanium transistor for the fast-growing pocket-radio and industrial-computer fields. Last week Texins set its sights on still another profitable business...
