Title: Submaterial charger for electric melting furnace
Inventor: KITAYAMA KIYOYUKI
IPC: F27D3/00
Filed: 1989-06-12
Abstract: PURPOSE:To melt and disperse a submaterial effectively, and to equalize a composition and a temperature in a short time by forming an electrode in a hollow type and supplying the inside of a melt with the submaterial and an inert gas from a lower-end opening section while the hollow section is used as the charging path of the submaterial. CONSTITUTION:A hollow type electrode 3a is employed as the electrode of an electric melting furnace, the hollow section of the hollow type electrode 3a is used as the charging path 6 of a submaterial, the submaterial charging path 6 is connected to a submaterial supply source and an inert-gas supply source, and the inside of a melt is supplied simultaneously with these submaterial and inert gas from a lower-end opening section 60 dipped into the melt of the submaterial charging path 6. The submaterial fed is heated and melted excellently because a section near the electrode is kept in a high temperature region at that time, the elevation of the submaterial is promoted because the melt is lifted by a convection in the vicinity of the electrode, and apparent specific gravity is reduced and the submaterial is elevated quickly and diffused rapidly extending over the whole inside of the furnace because the inert gas is mixed additionally. Accordingly, the submaterial is melted and dispersed effectively, thus equalizing a composition and a temperature.

Title: Testing method for nonlinear resistor of zinc oxide
Inventor: WATANABE MISUZU
IPC: G01R31/50
Filed: 1981-09-21
Abstract: PURPOSE:To decide the quality of the life characteristic of a nonlinear resistor of zinc oxide accurately in a short time, by utilizing the correlation between the heat-stimulated current characteristic and the life characteristic. CONSTITUTION:When the temperature of an element substance is raised at a prescribed rate, a current flows in such a way that it has one large peak and several small peaks located on the opposite sides of the large peak corresponding to the temperature. This is a temperature-stimulated current (TSC), and said peaks are named I1, I2, I3 and I3' from the left to the right. When this measurement of current is applied to a sample l1 without heat treatment, a sample l2 with optimum heat treatment, and a sample l3 with overheat treatment, the TSC characteristic shown by the graph is obtained. According to the graph, l2 is positioned in between l1 and l3, and the maximum peak of l2 is positioned leftest in patterns. It is made clear thereby that the peaks of TSC relate to the temperature of heat treatment. Since a leakage current tends to increase more in l1 and l3 than in l2, the life characteristic can be known from the peaks of TSC.

Title: Hot-cathode discharge lamp
Inventor: OBARA AKIO
IPC: H01J61/10
Filed: 1985-07-10
Abstract: PURPOSE:To prevent consumption of emitter and blackening of tube thus to achieve long service life by employing the cathode face of shield in opening direction as the discharge face and returning the emitter dispersed or evaporated from said discharge face through electromagnetic force to the original discharge face. CONSTITUTION:The discharge face 24 of hot-cathode 2 is opened but the sideface is surrounded with shield 3 tightly to scarcely evaporate nor disperse the emitter 22 from the sideface. On the discharge face 24, the shield 3 is the anode at any time thereby dispersed emitter particles 25 are returned by electromagnetic force as well as collision with starting gas or mercury vapor to the discharge face 24. Consequently, consumption of emitter 22 on the discharge face 24 is low thus to never blacken the tube wall. The inner face of shield 3 is partially adhered with discharge emitter particles 25 but since the shield 3 will never be the cathode, it is not discharged from the inner face of shield 3.
