    Asynchronous sequential logic using NOR/NAND integrated circuits is extensively used in fast digital systems. The standard design procedure results in a set of excitation equations for the secondary variables, which must be examined (and corrected) for static logical hazards prior to implementation. A modified design technique is postulated which allows sequential circuits to be implemented direct... View full abstract»

    Experiments which use coherent waves at frequencies near 1010 Hz are possible in suitable materials at low enough temperatures. The techniques which are used are determined by the very short acoustic wavelength (¿ 5000 Å) and by the availability of transducers and detectors. An interesting area of research is into their use for spectroscopic purposes in crystals, a technique which is complementa... View full abstract»

    The paper describes three approaches to the problem of manufacture of capacitors by methods compatible with thick film technology. In the first, the capacitor is regarded entirely as a discrete component and is manufactured or purchased independently. The problems of integration become those of surface bonding and of the protection of devices with irregular outlines. The second approach is to prod... View full abstract»

    The digital multiplication of two numbers of any sign by the successive addition of partial products is critically examined for the purpose of reducing the time of computation. The theory of Booth's method is reviewed and extended to show its validity for use with numbers of any radix. Multiple digit multiplication algorithms can then be derived and the quaternary algorithm for the multiplication ... View full abstract»

    The paper describes a multi-layer interconnection system suitable for 50¿100 unencapsulated integrated circuit elements of the type used in high-speed computers. The power and earth planes with their associate dielectrics are made using the thick film technique. Methods of producing the conductor and dielectric films are discussed. Two additional conductor planes, forming the signal matrix in whi... View full abstract»

    A system for general classification of non-uniform transmission lines¿by transforming the independent variable x (representing distance) of the telegraphists' second-order linear differential equation to another independent variable w = F(x) which is some function of x and then by constraining the transformed telegraphists' equation to simulate a standard second-order linear differential equation...

    For low-value capacitors (tens of picofarads) glass dielectrics have been chosen, whereas for higher values it has been necessary to use a mixture of a high-permittivity ceramic and a binder material. Existing thick-film conductor compositions have been used for electrodes. In the work on the low-value systems, a large number of combinations of different dielectric and electrode materials and thei... View full abstract»
