    Huge piles of garbage lie rotting in the streets of New York City as we write this message. Meanwhile, elsewhere, urban technologists are meeting to discuss highly efficient systems to remove refuse regularly and inconspicuously from metropolitan streets. The two images are incongruous. The New York rubbish heaps may be partly due to work slowdowns resulting from layoff threats by a City administration in severe financial straits, but an executive of the Sanitation Department insists it is simply a matter of the difficulty in redeploying a somewhat reduced sanitation force ¿ the workers are presumably willing but confused.

    Certain concerns of engineers overarch all their special skills, efforts, and knowledge. On the one hand, there are ¿tools¿ of the electrical engineering trade: those general design techniques and methods of information-gathering that make all engineering design tasks feasible. On the other hand, there are avocational activities: the ¿toys¿ that can give added meaning to the engineer's life whether he is actively working or in retirement. View full abstract»

  • Tools III/Design techniques: Designer's bookshelf: The experts' choices in five major categories: CAD, design automation, and design techniques for microwave, power, and general systems

    With thousands of design books available, covering all the electrical and electronics fields of interest, Spectrum decided to identify some of the top books. The list on these pages is limited to five design areas, chosen because they are related to other articles in this issue. The books were recommended after consultation with experts in computer-aided design and modeling, design automation, general systems design techniques, microwave design techniques, and power systems design techniques and planning. Books in these areas cover (and often overlap) such disciplines as decision review, decision analysis, and pattern matching. View full abstract»

    With microprocessor technology developing at a faster pace than most design engineers can follow, the need for special forms of education ¿ to prepare engineers to evaluate and use these new systems-on-a-chip ¿ has become evident. Responding to this need, conferences and publications concerned with conveying knowledge and up-to-date information about microprocessors have mushroomed. View full abstract»

    The following is a guide to some of the sources where researchers, or the casual questioner, can find the data they need in a number of engineering and engineering-related areas. In addition to the specific categories listed, information on a variety of technical subjects is available from the Engineering Societies Library and from Engineering Index, both at 345 East 47 Street, New York, N.Y. 10017. For tabulations of reference materials, literature guides, retrieval services, and abstracting and indexing services, the reader is referred to Madhu-Sudan Gupta's Spectrum article, ¿Where to find it when you need it¿ (May 1974, pages 72¿77). And elsewhere in this issue (pages 68¿71), Oscar Firschein tells you how to keep up to date with ¿On-line reference searching.¿ View full abstract»

  • Tools VII/Information retrieval: On-line reference searching: `Let your computer do the walking¿ ¿ it can be fast, thorough, and inexpensive

    If you are surrounded by experts who can answer your every question, or if you are a researcher in a narrow field of specialization and communicate with other leaders in the field throughout the world, or if your work is ¿cut and dried¿ and no problems arise that require outside reference work, then you are in a near utopia and computerized retrieval is not for you. On the other hand, if you are finding it difficult to track your field and feel that some of your problems may be answered in unfamiliar journals, government reports, or foreign journals; or if you lack access to an adequately equipped technical reference library; or if you desire to be informed automatically and quickly of the latest references in your field; then computerized retrieval may be the very thing you need.

  • Toys I/Survey: The EE at leisure: Scores of readers responded to Spectrum's mini-study of how they invest, or while away, their spare hours

    Though different in many ways, leisure and work activities may be highly interactive. While a job can pay for or prohibit leisure activities, the quality of a worker's leisure time may well determine, as much as does the job, how satisfied that worker feels with life in general. An involved, happy engineer is likely to be performing well in all of life's arenas. And, as one of Spectrum's editors put it, leisure that is fruitful can be a solid measure of a man ¿ or woman.

  • Toys II/Avocation: Inside amateur radio: Devoted to public service transcending geographical and political boundaries, today's ham is not a mere tinkerer

    An off-duty taxicab driver points his antenna in a predetermined direction, carefully tunes his receiver around an expected frequency, and picks up satellite tracking beacons. A student ¿ a grade-schooler ¿ flicks a switch and she and her classmates are greeted from outer space. A mother paces back and forth in the corridor of a Colombian hospital while her daughter lies unconscious in an intensive-care unit. Thousands of miles away in Cincinnati, Ohio, an amateur radio operator picks up a medical emergency: a Colombian child will die without drugs only two hospitals ¿ one in Chicago, the other in California ¿ can provide. A few phone calls and the drugs are on their way to Bogota. View full abstract»

  • Toys III/Avocation: A collector's guide to romance and nostalgia: Where to find antique vacuum tubes, TRF receivers, glass insulators, dc generators, and old trolley cars

    Documenting the history of their profession seems to be a popular leisure-time pursuit among electrical and electronics engineers. Collectors and collections abound. Exhibitions range from one at the prestigious Smithsonian, where there are warehouses full of donations still to be unpacked, to small private collections of glass insulators or telegraph keys. The following list serves not only the dedicated historian but the casual sightseer who might be interested in anything from old-time trolleys to antique telephones to memorabilia of some of the profession's best-known pioneers. Exhibit locations are called out in blue so that readers can identify items of interest in their areas, and it should be noted that the list presents only a sampling of the many collectors and groups actively devoted to preserving the romance of engineering's past ¿ and its artifacts.

    In case you weren't aware of it, there are magazines on everything! Spectrum found this out when it set about putting together a reference bookshelf on EE leisure-time activities. What follows is a selection of some key magazines on the most popular of those activities, as well as a listing of current books recommended, for the most part, by the editors of those magazines. The bookshelf is organized by popularity of the activity (see this issue, pp. 72¿75), beginning with photography. View full abstract»

  • New product applications: IC op amp combines high-voltage JFETs with standard bipolar transistors on one chip

    Publication Year: 1975 , Page(s): 83 - 89
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1035 KB)  

    This low-noise, high-performance, operational amplifier, part of a series, incorporates junction field-effect transistors (JFETs) on the same chip with standard bipolar transistors. The 15 op amps in the series replace expensive hybrid and module devices in such applications as precision high-speed integrators, fast A/D and D/A converters, high-impedance buffers, logarithmic amplifiers, sample-and-hold circuits, photocell amplifiers, and amplifiers that combine wide bandwidth, low noise, and low drift.
