    摘要: A dimmer noise reducing circuit wherein vibration noise accompanying the activation/deactivation of a piezoelectric transformer can be reduced, while non-uniformity of brightness of a discharge lamp can be prevented. A chopping circuit turns on/off an output from an input voltage source in a given periodic manner and a full-bridge circuit that receives an output voltage (vb1) of the chopping circuit. An output from a lowpass filter is supplied to a piezoelectric transformer, an output current of which (Io) is supplied to a discharge lamp. The full-bridge circuit is controlled by a full-bridge drive circuit to switch the input voltage (VB1) from the chopping circuit. The drive frequencies of the FETs of the full-bridge circuit are decided by a voltage-controlled oscillator. The chopping circuit is connected to a duty varying circuit the full-bridge circuit is caused to operate with its duty fixed.

    摘要: A semiconductor X-ray detector device has an i layer configured to substantially a circular cylindrical shape but not a conventional top-hat shape and a p layer provided to substantially cover the circumferential side of the i layer. Both an n+ layer and an n surface electrode are arranged smaller in the area than the bottom at the n surface electrode side of the i layer in order to expose the i layer entirely to the electric field E. Accordingly, the spectrum remains not fractured in the profile when the n+ layer and the n surface electrode are not greater in the area than 33% of the bottom at the n surface electrode side of the i layer, hence permitting the resolving power to stay high.

    摘要: An ink jet print head comprises a substrate formed with a heating resistor, an ink path defining member for defining an ink supply path, and a orifice plate, and in the orifice plate, there is formed an ink outlet at the position opposing the heating resistor. Further, a heating zone surrounding the heating resistor is formed at the position corresponding to the heating resistor of the ink supply path. The channel resistance of the ink supply path is set so that a relationship is established between a quantity q of the discharged ink drop, a sectional area A of the ink outlet, and a maximal projection h that a meniscus of the ink has when it projects from the ink outlet after it has restored the exit level from a retreat position it had after the drop of the ink had been discharged, such that 0
