Abstract: 1467866 Non-linear resistors TOKYO SHIBAURA ELECTRIC CO Ltd 14 Aug 1974 [20 Aug 1973] 35837/74 Heading H1K [Also in Division H2] In apparatus for starting a gas discharge lamp, particularly a fluorescent lamp 3, a sintered oxide resistor 4 is connected between the electrodes 2a, 2b, the resistor 4 has a voltagecurrent characteristic such that it is conductive when the inter-electrode voltage is high, i.e. before the discharge starts, and the resistance is high when the inter-electrode voltage is low, i.e. when the discharge is in progress. The electrodes 2a, 2b are directly heated and in series with the sintered oxide resistance 4, and also with a choke 5 and a power source 6. When power is switched on, high current flows through the electrodes 2a, 2b, which are heated so that the discharge in the lamp starts. Thereupon the voltage between the electrodes falls, and the value of the sintered oxide resistor becomes high. The sintered metal oxide resitor comprise 60-90 mol per cent of ZnO, 10-40 mol per cent of MgO, and 0À1-20 mol per cent of MnO 2 ; or preferably 70-74 mol per cent ZnO, 16-20 mol per cent of MgO, and 8-12 mol per cent of MnO 2 . Other compositions are referred to in the Specification. The composition is chosen according to the working voltages of the lamp. Reliability may be increased by connecting a rectifier (7) in series with the sintered oxide resistance 4 (see Fig. 2, not shown).
