Abstract: A power source control circuit for a gas discharging tube, for example, a xenon lamp, and a xenon lamp signal lighting device adopting the same, are provided, in which power can be supplied for a relatively long time to a plurality of xenon lamps having a high starting voltage and a large lamp current with a small capacity battery, and a designation of emission and/or a flickering interval of at least one xenon lamp of a multi-color filter type can be easily controlled.

Abstract: An improved compact generator, a light-emitting wheel adopting the same and a manufacturing method are provided. To make a generator compact and light to smoothly perform electromagnetic induction by crossing the directions of magnetic flux of an armature coil and a permanent magnet, an assembly structure including an armature arm and the armature coil is improved. To prevent damage by impact to the permanent magnet and use a rare-earth based permanent magnet in a ring type having the thickness of 1.2 mm in Lanthanides which has a magnetic force 9-10 times stronger than that of a ferrite based permanent magnet but is weak against impacts, a permanent magnet assembly is provided in which the permanent magnet is arranged on a buffer.
