    摘要： The present invention relates to a high-intensity discharge lamp (1) comprising a discharge vessel (2) enclosing a filling in a discharge chamber (3), and a pair of electrode rods (4, 5) being formed of a material which is free of thorium and protruding from opposite sides into the discharge chamber (3). The diameter ED of the electrode rods (4, 5) in the discharge chamber (3) satisfies the formula (I), wherein W represents the value of the nominal lamp power in mW and Ed represents the value of the distance of the electrode rods (4, 5) in the discharge chamber (3) in mm, and wherein the nominal lamp power W is between 20 W and 50 W. With the above formula, high-intensity discharge lamps can be easily designed with different nominal powers and/or 10 electrode distances without time consuming experiments in order to achieve an optimum performance.

    摘要： A discharge lamp includes a cathode in a luminous tube, and an emitter, other than thorium, is added to the cathode. The emitter is prevented from being excessively vaporized from the cathode and depleted soon. Smooth lighting is enabled even at start-up. A main body part (31) of the cathode (3) is made from a metallic material having a high melting point and containing no thorium. A front end (32) is made from a metallic material having a high melting point and containing an emitter (excepting thorium). Inside a sealed space (33) formed in the main body part (31) and/or the front end part (32) is received a sintered compact (34) containing an emitter (excepting thorium) that is higher in concentration than the emitter contained in the front end part (32).

    摘要： A tungsten cathode material to be used for TIG welding, plasma spraying, plasma cutting, electro-discharge machining, discharge lamps, and the like is improved; use of the radioactive element thorium is reduced; and a long life and a high performance are realized. In a tungsten cathode material, oxide particles containing an oxide or oxides of at least one selected from the group consisting of Sm, Nd, Gd, and La in a total amount of 50 vol% or more are dispersed, the oxide particles having an average particle diameter d satisfying the relationship 0 µ m. Given a volume fraction f (vol%) of the total amount of the oxide particles in the tungsten cathode material, 0.083≦f/I holds when a current I (A) such that 0
