Title: Low pressure discharge lamp
Inventor: SHIMIZU TAKAO
IPC: H01J61/24
Filed: 1992-08-31
Abstract: PURPOSE:To obtain a low pressure discharge lamp having a good appearance free from blackening by determining the width of a mercury dispenser used as an electrode enclosure within a specific range of size. CONSTITUTION:A mercury dispenser is welded to be fixed on a ring by using a material formed by applying Zr-Ti-Hg alloy 8 on a nickel plate 7 having width of 4mm or more and 5mm or less so that it encloses a filament 9. When the width of the nickel plate 7 becomes 5mm or more, the shadow of the enclosure appearing during lighting a lamp makes lighting appearance worse and when it is 4mm or less, the enclosure can not show its effect sufficiently to cause blackening. Though a welding margine having width of 1.5mm is provided on upper and lower parts of the alloy 8 because welding can not be carried out in the area of the alloy 8 but if the width of a plate 7 is made 5mm or less, the width that allows application of the alloy 8 becomes 2mm or less so that the quantity of mercury is insufficient depending on the kind of the lamp. Therefore, it is effective to apply the alloy in the manner of (d).

Abstract: PURPOSE:To enable the application of an apparatus to the discharge of a plasma for a long time of 1,000sec or more in a nuclear fusion apparatus, by measuring the value of a current flowing through a pickup coil. CONSTITUTION:A pickup coil 2 of a superconductor, a resistor 5 for measuring a current flowing through a switching element 3 and the coil 2, and a means to measure a voltage generated in the resistor 5, are provided. In the coil for which the superconductor is used, a magnetic flux linking to the coil itself is kept up. When the element 3 is closed, in other words, a superconducting current flows through a loop constituted by the coil 2 and the element 3. In the coil put in a magnetic field and found in a superconducting state, consequently, the superconducting current flows in accordance with a change in the magnetic field so that the magnetic flux linking to the coil is kept up. Therefore, the current can be determined and the magnetic field at that time can be measured by opening the element 3 and by measuring the voltage generated in the resistor 5, at the time of measurement of the magnetic field.
