 LATHAM, NY, Aug. 19 /PRNewswire/ -- A semiconductor power control device invented by Harris Semiconductor scientist Dr. Victor A. K. Temple has been recognized by R&D Magazine as one of the year's most technologically significant new products. Dr. Temple is head of the company's Power Research and Development activity in Latham, N.Y.
 The device, known as an MCT (Metal Oxide Silicon-Controlled Thyristor) is one of the technology breakthroughs needed to make practical electric cars available in time to meet mandated deadlines for zero-emission vehicles. The invention can also benefit next-generation airliners, spacecraft and ocean vessels, industrial applications and electric power distribution systems.
 The Harris MCT was chosen by a panel of scientific experts and the magazine's editors for one of the 1993 R&D 100 Awards. R&D Magazine has annually honored inventors and scientists around the world since 1963 by selecting the 100 most technologically significant new products and processes. Corporations, government labs, private research institutes, and universities throughout the world vie for this "Nobel Prize" of applied research. Past winners include such products as Polacolor film, the electronic video recorder, anti-lock brakes, the automated teller machine, halogen lamps, the fax machine, a lens stabilizing system for camcorders, and the Nicoderm transdermal patch. This year's winning products are being honored in a three week exhibit at Chicago's Museum of Science and Industry opening Aug. 20.
 Smaller than a postage stamp and only slightly thicker, the Harris MCT has high current-handling capacity, fast switching speeds and low electrical losses, generating less heat and needing less cooling than earlier control circuits. In the case of electric automobiles, this translates into significantly greater range per battery charge.
 Dr. Temple's group plans further improvements with an innovative copper-on-ceramic packaging technique patented by Harris that lets MCTs tolerate high temperatures and reduces package volume by nearly an order of magnitude. With aircraft, this leads to simplification of airframe and engine design with weight and maintenance cost reductions and improved reliability and fuel efficiency. Similar benefits, including higher payloads, could apply to future space shuttles, satellites, and the international space station program.
 The U.S. Navy sees a pivotal role for MCTs in the development of modular, lower cost electrical propulsion and power systems for both Navy and commercial vessels. And the Electric Power Research Institute (EPRI), which helped sponsor early development work on the MCT, is studying how it can be used along a network of power lines to instantly reroute power when necessary, making the nation's power system more stable and averting blackouts. MCT-type devices eventually may be able to double the amount of power carried along some major transmission corridors by enabling present AC distribution lines to be converted to DC.
 In the view of Dr. William U. Borger, the civilian chief of the U.S. Air Force's Aerospace Power Division, Aerospace Propulsion and Power Directorate, Wright Laboratory, the new Harris device "reestablishes the United States as the leader in power semiconductor innovation," strengthening America's semiconductor industry against foreign competition.
 In addition, a ranking EPRI researcher calls the MCT "the ultimate power control device".
 Harris Corporation's Semiconductor Sector manufactures discrete semiconductors and integrated circuits for analog and digital signal processing and power applications. It is the number one supplier to the military and aerospace market and the seventh largest U.S. merchant semiconductor manufacturer. Harris Corporation (NYSE: HRS), with worldwide sales of more than $3 billion, is focused on four major businesses: electronic systems, semiconductors, communications, and Lanier Worldwide office equipment.
