Field-effect Transistor Raises Semiconductor Frequency Range

The “field-effect” transistor is one of the latest additions to the transistor family. Although it operates on a principle quite different from that of the point-contact or junction type, it is capable of performing many of the same functions such as amplification or oscillation, and it has the advantages of small size and low power consumption common to the others.

Gas Turbine Improves Performance

The introduction of the helicopter, noted for its low-speed flight characteristics, appears to be an incongruous note in the transport race. A second glance reveals that the helicopter, like the jet transport, is being introduced to keep up with civilization’s rapidly increasing living pace.

Beech Should Reach Jet Decision By Fall

Beech Aircraft Corp. could roll out the first U. S. production version of the twin-jet Morane-Saulnier MS-760 business plane in one year, says Jack Gaty, vice president-general manager. The new 400-mph., four-place executive plane will cost approximately $300,000, according to Beech officials.

New Fighters Use Resin-bond Honeycomb

San Diego—Honeycomb structures developed for high-production applications are helping to accelerate the structural revolution in aircraft detail design. All-metal honeycomb sandwiches—bonded by resistance welding or brazing —are still largely under development; resin-bonded sandwiches structures have been refined for production use.

Now It’s Defense News Only If It’s ‘useful, Valuable Or Interesting’

Washington, D. C.—New formulas to help Defense Department officials withhold unclassified information from the public are being promulgated from the Pentagon. One of them is a “guide” that asks military news sources to evaluate “anything you can think of” in deciding whether to supply the answer to a question.
