    摘要: A method and apparatus for operating a high pressure discharge lamp is disclosed. Oscillation in the discharge arc periphery, a problem that occurs with high frequency operation, is eliminated. A high pressure discharge lamp is operated by applying thereto a dc or rectangular wave current to which is superposed an ac component shaped by a high frequency ripple signal that has been amplitude modulated by a modulation signal for inducing instantaneous fluctuations in the power supply input to both ends of the arc gap. The ripple level is thereby temporally varied, and stable operating is possible even when exceeding the ripple level at which oscillation in the arc periphery begins.

    摘要: A fill material 201 enclosed in an arc tube 201 with an inner diameter of 10.8 mm includes ScI3, argon, and mercury. A distance between electrodes 202 is set at 2.2 mm, and a distance between the inner wall of the arc tube 201 and the electrodes 202 is set at approximately 5.4 mm, which is approximately twice the distance between the electrodes 202. The lamp of the present invention is capable of forming thin arc and thereby achieving high luminance since only the metallic elements having an ionization potential of 6 eV or higher is contained in the fill material 207. The restriction of the short distance between the electrodes serves to stabilize arc. Scandium in the fill material serves to achieve a good color reproduction characteristic.

    摘要: A high-pressure discharge lamp includes an arc tube. The arc tube is supplied with electric power having a frequency at which substantially only one sound standing wave occurs in the arc tube. The sound standing wave is of a given mode, and is in a radial direction with respect to the arc tube. The given mode corresponds to, for example, a first-order mode. Preferably, the arc tube satisfies a relation as follows:(n+0.2).ltoreq.2L/D.ltoreq.(n+0.8)where "n" denotes a natural number, and "L" denotes an axial length of an interior of the arc tube and "D" denotes an inside diameter of the arc tube.

    摘要: An electric power converter can include an electric power converter case mounted on rolling stock, a unit mounting section formed in the electric power converter case and having a cooler insertion opening, and an internal unit mounted on the unit mounting section. The internal unit can include a cooler projecting from the unit mounting section through the cooler insertion opening into an outside air introduction section into which the outside air is introduced and a plurality of securing holders made to butt against the unit mounting section for securing the internal unit. Each of the securing holders can have a butting surface for butting against the unit mounting section to form a step by making the butting surface protrude from the opposed surface of the internal unit facing the unit mounting section.
