    Industry specialists do most of the fabrication of glass-sealed headers for suppliers of hermetic electronic components. Too often, these specialists are not acquainted with the effect that header processing can have on component fabrication, assembly or use. Almost as frequently, the component maker is unable to relate his own processing difficulties to problems introduced during the previous han... View full abstract»

    The electrical current through silver contacts evaporated onto n-type gallium arsenide as a function of surface treatment is reported. Contacts to untreated gallium arsenide exhibit the expected high resistance. Surface cleaning by argon ion bombardment reduces the resistance by three orders of magnitude. The electrical resistance beyond 850 eV increases rapidly with ion bombardment energy. The re... View full abstract»

    We investigated the effect of a reduction of the protective gas pressure at fixed static breakdown Voltage on the appearance of showering (intermittent arcing) in dry reed contacts that break inductive circuits by using a discharge gap arid an auxiliary interruptor to simulate this condition. We found a critical pressure range, where showering, capable of causing strong erosion, is replaced by glo... View full abstract»

    The principles governing the operation and performance of devices utilizing mesomorphic anisotropic fluids (liquid crystals) am reviewed and systematized according to materials, dielectric type, and mode of operation. A further breakdown is made into whether the phenomenon is a change in optical density (color), diffraction, or scattering. Some of the possible directions for optical applications a...

    General properties of electronic ceramics are examined, noting especially their influence upon fabrication economics and quality. Particular emphasis is placed upon the preparation of sinterable powders to attain high densification. The effects of fabrication technique and powder preparation upon ceramic quality and dimensional control are pointed out. Recent developments and possible future trend... View full abstract»

    A comparison has been made of high strength filament materials having low dielectric and loss-tangent properties for use in antennae cables; lines and guys. The availability of type S glass fibers of higher strength than type E and the more recent production of high-modulus carbon filaments, and high-modulus organic type polymeric fibers offer several materials to choose from for optimum design. S... View full abstract»

    The purpose of this paper is to give the nonspecialist some tools he can use to gain insight into some of the complex thermal problems encountered in electronic assemblies. Some causes of thermal problems in electronic components and assemblies are briefly reviewed on a fundamental level. This review includes a discussion of some basic thermal parameters, the effect of the thermal environment on o... View full abstract»

  • Miniaturization of Delay Lines Through the Use of the Dielectric and Structural Properties of Plastics

    Publication Year: 1972, Page(s):51 - 57
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (936 KB)

    A miniaturized delay line wound on a sectionalized plastic spool is described. The surfaces of the spool and flange separators are coated with a silver paint which serves as a capacitor electrode. The other capacitor electrode is a winding conductor and the capacitance is derived from the wire insulation. To raise the capacitance the spaces between turns of the windings and between the windings an... View full abstract»
