    Methods of testing disk packs on an amplitude detection principle are widely used at present for initial testing, but the detection methods used in computer systems are based on a time detection principle which is less sensitive to changes of amplitude. This paper outlines the usefulness of amplitude detection as a method for testing disk packs and compares it against a technique based on time det... View full abstract»

    A new calculation is made of the noise (excluding excess noise) in p-n junction diodes and bipolar transistors. The theory is based on an analysis of the current waveforms caused by thermal motion of individual carriers and by individual recombination events in a one-dimensional model; unlike that of van der Ziel (1955) it does not rely on arbitrary assumptions about thermal fluctuations in carrie...

  • Electrical conduction in thin lubricating oil films

    Under conditions of hydrodynamic lubrication oil forms a thin film between the lubricated surfaces. An investigation of the electrical properties of such films is described, the measurements being made under dynamic conditions. It is shown that the electrical conduction is consistent with space-charge limited current in the presence of a uniform distribution of traps. The oil film is considered to... View full abstract»

    This paper describes two of the basic types of thin film magnetic recording heads which have been proposed. The advantages and disadvantages of the heads are discussed. The production techniques and magnetic. materials which have been employed in the manufacture of these heads are critically examined. Finally, the available experimental results on thin-film magnetic recording heads are compared wi... View full abstract»

  • A frequency domain stability criterion for non-linear feedback systems

    Publication Year: 1974, Page(s):157 - 165
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (875 KB)

    A criterion for the investigation of the stability of a certain class of non-linear system with sinusoidal input is proposed. It is derived from the concepts of the describing function method and the circle criterion. If the non-linear system satisfies the restrictions of describing function analysis and if the characteristic of the non-linearity is bound in a sectory/e¿[a, b], there exists a cri...

  • A method for obtaining three-dimensional optical images with minimal primary distortion from microwave holograms

    Publication Year: 1974, Page(s):167 - 172

    A new method is presented for the reconstruction of almost distortionless three-dimensional optical images from microwave (or other long wavelength) holograms. The strategy for overcoming the axial elongation of an optical image from a long wavelength hologram scaled down by a factor less than the ratio of the two wavelengths used, is demonstrated using a computer simulated microwave hologram.
