Abstract: A driving method of external electrode fluorescent lamp inverter for backlight. In the driving method, a square wave voltage frequency for driving the external electrode fluorescent lamp is applied to the primary side of a transformer in the region whose frequency is substantially ½ of the resonant frequency which is determined by the capacitance of the external electrode fluorescent lamp and the leakage inductance of the transformer. Then, the external electrode fluorescent lamp is caused to emit light by the self-discharge to thereby obtain high efficiency and high luminance.

Abstract: The present invention relates to a medicine bottle for injection capable of separately storing medicine powder and a solvent such as a saline solution in a single medicine bottle and conveniently mixing them therein in use. An inner wall 6 is provided to extend upwardly from the bottom of the medicine bottle therein such that the interior of a body 2 of the medicine bottle is partitioned by the inner wall into a portion 8 for storing the medicine powder and a portion 9 for storing the solvent but the portions communicate with each other at an upper end of the body 2.
