  • What are microsystems?

    Publication Year: 1961, Page(s): 482
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (529 KB)

    The complexity of modern electronic systems has brought about urgent needs for increased reliability and major reductions in size and weight. Microsystems present solutions to these requirements. Beyond providing answers to the immediate problems, microsystems will revolutionize systems engineering and manufacturing design procedures and tend to encourage standardization of basic subsystems.

  • Ampere-turn gain of ordinary saturable reactors

    Publication Year: 1961, Page(s): 487
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (584 KB)

    THE ampere-turn gain is a fundamental quantity of ordinary saturable reactors. In the case of an ideal core material with a step-shape B-H characteristic (rectangular B-H line), the relation between load-winding ampere-turns ILNL and control-winding ampere-turns ICNC becomes a straight line, which for identical scales of ampere-turns subtends an angle of...

  • Some recent developments in “integrated electronics”

    Publication Year: 1961, Page(s):488 - 499
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (8696 KB)

    Integrated electronics is the new frontier in the development of the electronics industry. It characterizes microsystems in which the number of parts are considerably less than the number of equivalent components. Some of the steps in the development of microsystems leading to the process of integrated electronics are briefly described and illustrated by several working devices. View full abstract»

  • A concept for microsystems electronics

    Publication Year: 1961, Page(s):500 - 502
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2359 KB)

    In microsystem design, size and weight reduction are not the sole considerations. Also important are strength, reliability, design flexibility, heat drain, and costs. Means for automatic insertion of devices and simplicity of interconnection should be provided. All these influences are illustrated in the discussion of the assembly of Microseal diodes and transistors, and small passive components, ... View full abstract»

  • A method for the design of holding electromagnets

    Publication Year: 1961, Page(s): 503

    IN DESIGNING cylindrical holding electromagnets, which consist of a ferromagnetic core, with stationary and movable portions, interlinking a coil of wire, it is desirable to proceed from the specified mechanical and electrical characteristics directly to the physical dimensions of the magnet without the use of trial-and-error methods.

    The molecular electronics approach to microsystems considers the electronic function to be performed, then attempts to synthesize its characteristics within a suitable solid material. It is expected that this approach will lead to many new concepts in the realization of electronic functions. View full abstract»

    A theoretical analysis is presented on the operation of a computer logic component exhibiting current commutation between two hook collectors. A quantitative theory is established for the current-multiplying hook collector and for many factors contributing to the interaction between such collectors. Appropriate equations are presented in graphical form throughout a range of physical and geometrica... View full abstract»

  • Analysis of switching surges on a 220-kv line

    Publication Year: 1961, Page(s): 524
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (574 KB)

    IN RECENT YEARS, improvements in lightning arrester characteristics have permitted reductions in transformer insulation levels and have led to extensive analysis and investigation of switching surges. Before the common use of reduced BIL transformers, switching surges were of no concern in most cases, since their magnitudes were well below the insulation strength of the windings. As transformer BI... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (545 KB)

    JOULEAN HEAT generated when an electric current passes through a conductor is considered to be an undesirable by-product by the majority of electrical engineers engaged in designing electric apparatus and, therefore, great care is taken to reduce it to a minimum in these designs. Electric heating element designers, on the other hand, are continually searching for new ways to generate more heat. In... View full abstract»

    An important microminiaturization technique is that of realizing complex network components by means of resistive and dielectric films. A general method for analyzing these film-type networks, built around the theory of indefinite matrices, is presented and simple rules are developed for generating subnetworks from a given 4-terminal network.
