    Voltage regulation has been a specialty of semiconductors since the introduction of the Zener diode well over a decade ago. Now, there is a new dimension to the field¿the monolithic voltage regulator. Available in a number of configurations that have specific advantages ranging over a variety of applications, this new component not only is giving its discrete counterpart a run for the money, but ...

    To supply the mounting demand for electricity in the Federal Republic of Germany, a network has been built that consists of 380- and 220-kV multiple bundles. Multitiered towers are used to support the conductors because available land is a limited, expensive commodity. As far back as the 1920s, 220kV, in the scope of an emerging interconnected system, became a necessity for covering great distance... View full abstract»

    Blanket agreements between employers and employees, requiring the latter to relinquish in advance any claims to any ideas springing up during the term of employment, are considered illegal and against public policy in most highly industrialized countries¿with the notable exceptions of the United States and Great Britain. In the author's opinion, these agreements are eminently unfair to the creati... View full abstract»

    We are all aware that radio communication is not instantaneous. With the coming of satellite communication we have fallen prey to some of the consequences of telephony with long propagation time. So it is that when one person speaks to another via satellite link, he must wait perhaps 600 ms for a rejoinder. Such a delay, of itself, may not be too disconcerting, but in combination with echo it can ... View full abstract»

    The defense electronics industry is again faced with the prospect of cutbacks, which brings the problem of its conversion once more to the fore. At the same time, the growth of imports presages sharp competition for U.S. industry for the products it can devise to take up the slack. Further, the electronics industry has a quality problem, in its military, industrial, and consumer sectors. In this a... View full abstract»

    Ferroelectric ceramics exhibit piezoelectric effects and optical birefringence that are electrically controllable. Consequently, these ceramics are applicable to a wide variety of devices. An article in the February issue has already described electrically actuated light valves and electrically controlled optical filters. The present article deals with the piezoelectric behavior of ferroelectric c... View full abstract»
