  • Spectral Lines: A stirring giant

    Publication Year: 1986, Page(s): 27
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (338 KB)

    The intention of General Electric to acquire the RCA Corp. came as a blockbuster. Yet Monday-morning quarterbacks insisted the takeover was not improbable. GE's aggressive chairman, John F. Welch Jr., had put the corporate giant in a good position to execute such a coup. Among other things, he had divested over $5 billion worth of the corporation's businesses and reduced the workforce by nearly 10... View full abstract»

  • When reactors reach old age: Can an obsolete nuclear power plant site he safely and economically restored to its original environmental condition?

    Publication Year: 1986, Page(s):28 - 35
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3023 KB)

    It is pointed out that while the battle over whether to build new plants has quietened in recent times, a second struggle is shaping up in the United States as reactors approach a new stage of life: retirement. Four decades into the nuclear power age, questions of how best to dismantle and dispose of a nuclear power plant remain largely unanswered. Engineers have three choices in dealing with a re...

  • The quest for ballistic action: Avoiding collisions during electron transport to increase switching speeds is the goal of the ultimate transistor

    Publication Year: 1986, Page(s):36 - 38
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1055 KB)

    After describing how ballistic electrons can be created, the author outlines a working gallium arsenide ballistic transistor. The work that has been done in creating a silicon ballistic transistor is then surveyed. View full abstract»

  • Progress toward a metal-base transistor

    Publication Year: 1986, Page(s):38 - 42
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1990 KB)

    Interest has been revived in the silicon metal-base transistor because of significant progress in growing thin, single-crystal metal films on silicon. The unique properties of silicides are described and the possibility of attaining ballistic transport in silicides is discussed. The use of the metal-base transistor as a physical probe is considered. View full abstract»

  • Ballistic electrons in compound semiconductors

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1643 KB)

    It is pointed out that shorter transit times in transistors can be obtained by only two techniques: constructing a device with a shorter active length, and accelerating the electrons to a higher velocity with a ballistic launcher. The work that has been done on these two techniques is surveyed. Various devices incorporating ballistic injection are described. View full abstract»

  • A gallium arsenide ballistic transistor?

    Publication Year: 1986, Page(s):45 - 47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1323 KB)

    The authors review the work done in 1985 at the IBM Thomas J. Watson Research Center on measuring the ballistic transport of electrons in a gallium arsenide heterostructure hot-electron transistor. The device is referred to as the tunneling hot-electron transfer amplifier (Theta). The way in which the transistor functions as its own spectrometer is explained. The experimental results obtained with... View full abstract»

  • Gyroscopes may cease spinning: Optical gyroscopes without moving parts are more reliable and more rugged than conventional mechanical systems

    Publication Year: 1986, Page(s):48 - 53
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2293 KB)

    The optical gyro's greater reliability, wide dynamic range, and ability to withstand high-g fields and harsh environments make it superior to mechanical gyroscopes, with their spinning rotors and complex gimballed mounts. The principle of the ring laser gyro (RLG) is explained. The engineering difficulties that had to be overcome in producing the first RLGs are described, and current research tren...

  • A venerable giant sharpens its claws: General Electric's drive to increase profits and market share means drastic restructuring in product lines, employment, and manpower utilization

    Publication Year: 1986, Page(s):54 - 65
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4643 KB)

    An overview of the restructuring that has occurred at General Electric in product lines, employment, and manpower utilization is presented. These changes have been marked by a shift in emphasis from such businesses as power and household appliances to high-tech and service-related areas, for example medical systems and financial services. The effect of the changes on the morale of employees is dis... View full abstract»

  • Roboticists aim to ape nature: Engineers are thinking in new ways about sensing, chips, and robots as they study dolphins, slugs, and Homo sapiens

    The way in which bionics is affecting research and development in robotics is discussed. It is pointed out that mimicry itself is not the goal; rather, researchers hope that in building artificial analogues to biological systems they will discover principles that will advance both engineering and biology. Most profoundly, bionics is dissolving barriers between the science of the living and the art... View full abstract»
