摘要： In an ignition plug, since a ground electrode is formed in a thin-rod-shape or a mesh-like shape, sufficiently strong radicals are locally generated by a barrier discharge, an anti-inflammation effect by the electrode is small, and the growth of a flame is hardly hindered. Furthermore, by making the thickness dimension of a second dielectric facing a discharge region uniform, the barrier discharge is spread over the surface of the second dielectric, the generation of the radicals is maintained, and combustibility after ignition is promoted. Furthermore, because an end portion of a high voltage electrode and a ground electrode are disposed to face each other within a combustion chamber, a fuel gas introduced into the combustion chamber is liable to flow into the discharge region, and is easily ignited by the radicals generated due to the discharge.

摘要： A transformer includes a first iron core group, a second iron core group, and winding portions. The first iron core group includes iron core stacks. The second iron core group includes iron core stacks each disposed to face a corresponding one of the iron core stacks of the first iron core group. Each of the winding portions is wound around its corresponding iron core stack of the first iron core group and its corresponding iron core stack of the second iron core group, the corresponding one iron core stack of the second iron core group facing the corresponding one iron core stack of the first iron core group. The iron core stacks of the first iron core group and the iron core stacks of the second iron core group each include annular iron cores stacked alternately.

摘要： A power conversion device is provided between a power supply and a load, and converts power from the power supply and supplies the converted power to the load. The power conversion device includes a plurality of switching elements composed of semiconductor elements, and a control device which generates drive signals for controlling the plurality of switching elements. Voltages are respectively applied to the plurality of semiconductor elements, on the basis of the drive signals generated by the control device. The plurality of semiconductor elements have equivalent failure probabilities due to neutron beams. Thus, a failure of the power conversion device due to neutron beams is prevented, and size increase thereof is suppressed.
