    In this article, “normal” gauge is defined as an ordinary ionization gauge having its electrode system in glass tube, while “high speed” gauge is defined as an electrode system itself mounted directly inside the test dome.
    It was pointed out by Blears that in the region of high vacuum (p_??_10-6mmHg) high speed gauge shows much less reading than that of normal gauge. Why this difference occurs and where this comes from? If complete informations about the behaviors of two gauges were obtained, the mechanism of “pumping action” of normal gauge may be deduced.
    By using a specially designed oil diffusion pump, the behaviors of normal and high speed gauges having identical electrode systems were examined under various conditions. At room temperature, the reading of normal gauge is about 35% of the reading of high speed gauge. When cold trap of liquid nitrogen is used, the readings of two gauges approach mutually.
    Finally, attempts to explain the mechanism of “pumping action” of normal gauge are made, but any conclusion about it isn't given here.

  • Vacuum Evaporator for Copper

    In order to evaporate a large quantity of copper downward, the author designed a direct heating vacuum evaporator. It is composed of three molybdenum plate heaters each of which is suitably angled and fixed near to each other, so as to form a container for holding some of copper to be evaporated. Under the said container, a narrow gap is formed through which the molten copper is supplied to a downward opening and evaporated downward herefrom onts articles to be metallized. In these experiments, the rate of evaporation obtained was as high as 4. 17 mg · cm-2 · sec-1, and the distribution of deposits was quite reproducible.
