This book gives an overview of modern cathodes and electron emitters for vacuum tubes and vacuum electron devices in general. It covers the latest developments in field emission theory as well as new methods towards improving thermionic and cold cathodes. It addresses thermionic cathodes, such as oxide cathodes, impregnated and scandate cathodes, as well as photocathodes and field emitters – the latter comprising carbon nanotubes, graphene and Spindt-type emitter arrays. Despite the rise and fall of the once dominant types of vacuum tubes, such as radio valves and cathode ray tubes, cathodes are continually being improved upon as new applications with increased demands arise, for example in electron beam lithography, high-power and high-frequency microwave tubes, terahertz imaging and electron sources for accelerators. Written by 17 experts in the field, the book presents the latest developments in cathodes needed for these applications, discussing the state of the art and addressing future trends.

Engineered in Japan presents a unique and comprehensive examination of technology management in the most successful Japanese companies: unique in that all chapters go beyond superficial descriptions of stylized practices to look in depth at particular issues, often contradicting or qualifying the conventional wisdom; comprehensive in that it covers the entire technology life cycle from basic R&D, to development engineering, to manufacturing processes, to learning from the Japanese. Each chapter is based on original research by noted scholars in the field, and identifies technology management practices that have become a major source of competitive advantage for highly successful Japanese companies. Engineered in Japan documents the best practices from such companies as Toyota, Hitachi, Toshiba, and Nippondenso, and discusses how these technology management practices can be usefully adopted in other cultural contexts. Going beyond past observations, the authors all delve below the surface of Japanese management approaches. They look more closely than has been done before at how particular methods are applied, and they identify some new practices that have not yet been highlighted in books on Japanese methods. Presenting recent data that contradict some conventional thinking about U.S.-Japanese differences, they look at old techniques from a new perspective. "U.S. managers can perhaps learn more from the process of creation in Japan and the organizational structures that support innovation," say the editors in their introduction, "than from the particular approaches, tools, and technologies created." A running theme throughout the book is that Japanese managers and engineers tend to think in terms of systems, focusing not just on the parts but on the connections between them. Engineered in Japan is must reading for technology managers and engineers, along with anyone interested in Japanese business, engineering, and management.

This book presents a liber amicorum dedicated to Wolfgang H. Müller, and highlights recent advances in Prof. Müller’s major fields of research: continuum mechanics, generalized mechanics, thermodynamics, mechanochemistry, and geomechanics. Over 50 of Prof. Müller’s friends and colleagues contributed to this book, which commemorates his 60th birthday and was published in recognition of his outstanding contributions.

Japanese productivity and quality standards have fired the imagination of American managers, but until now there has been little explanation of how to do it -- how to apply Japanese methods at the actual operating level of U.S. manufacturing plants. This book shows you how, exposing otherwise well-informed westernized readers to a new world of management ideas. Author Richard J. Schonberger demonstrates that the Japanese formula for success is based on a number of specific, interrelated techniques -- stunning in their simplicity -- and he shows how these techniques can be put to work in American industries today. Here, in a clear, handbook format, are nine "lessons" for American manufacturers, introducing scores of techniques aimed at simplifying the overly-complex purchasing, inventory, assembly-fine, and quality-control processes of U.S. firms. At the heart of Japanese manufacturing success are two overlapping strategies: "just-in-time" production and "total quality control." Some American manufacturers already know a little about these methods, but Richard Schonberger provides the most comprehensive description of these techniques available: how they developed, how they all fit together, why they are so potent, and how they "snowball" -- unleashing a powerful chain reaction of productivity and quality control improvements each time more simplification is introduced. -- Publisher description.

Ultrafine bubbles (UFBs) are gas-filled bubbles with a diameter smaller than 1 μm. They are sometimes called bulk nanobubbles because these are not on a solid surface but inside a bulk liquid (water). They are already being used in commercial processes such as cleaning and plant cultivation. However, many mysteries still exist with respect to UFBs, such as mechanisms of stability, OH radical formation, and biological and medical effects. This is the first book on UFBs that reviews research done on them. It is helpful for those interested in the fundamentals of this emerging field and its applications, including cleaning, biological, medical, and dental students and researchers.

An exciton is an electronic excitation wave consisting of an electron-hole pair which propagates in a nonmetallic solid. Since the pioneering research of Fren kel, Wannier and the Pohl group in the 1930s, a large number of experimental and theoretical studies have been made. Due to these investigations the exciton is now a well-established concept and the electronic structure has been clarified in great detail. The next subjects for investigation are, naturally, dynamical processes of excitons such as excitation, relaxation, annihilation and molecule formation and, in fact, many interesting phenomena have been disclosed by recent works. These excitonic processes have been recognized to be quite important in solid-state physics because they involve a number of basic interactions between excitons and other elementary excitations. It is the aim of this quasi monograph to describe these excitonic processes from both theoretical and experimental points of view. we take a few To discuss and illustrate the excitonic processes in solids, important and well-investigated insulating crystals as playgrounds for excitons on which they play in a manner characteristic of each material. The selection of the materials is made in such a way that they possess some unique properties of excitonic processes and are adequate to cover important interactions in which excitons are involved. In each material, excitonic processes are described in detail from the experimental side in order to show the whole story of excitons in a particular material.
