A method for manufacturing a mold or an optical element provided with a fine surface roughness for anti-reflection or for diffusing, may include placing a substrate or a film made of a semiconductor or a metal into a reacting etching apparatus, introducing a mixed gas of sulfur hexafluoride and oxygen into the etching apparatus with the substrate or the film, tuning the mixed gas into plasma such that oxides are made to be scattered on a surface of the substrate or the film, and etching the surface of the substrate of the film by the sulfur hexafluoride while the oxides function as an etching mask to form the fine surface roughness on the surface of the substrate or the film. Further, etching conditions may be determined such that the pitch of the fine surface roughness is made from 3 to 18 micrometers.

This mobile terminal charging device has a support plate in which the front surface-side part is where a mobile terminal is installed, a charging coil disposed facing the support plate on the rear surface-side of the support plate, a plurality of detection coils concentrically disposed in the charging coil on a surface opposite the support plate, and a control unit connected to the detecting coils. When a charging operation is carried out, the control unit compares the difference between a voltage value detected using a first detecting coil among the plurality of detecting coils, and a voltage value detected using two detecting coils from a group comprising the first detecting coil and at least one detecting coil disposed outward of the first detecting coil. In addition, the control unit executes a safety operation in accordance with the results of the comparison.

This contactless power transmission device transmits power to a contactless power reception device having a reception-side coil and a reception-side resonator which resonates with the reception-side coil. The contactless power transmission device has a transmission unit including a transmission-side coil, a transmission-side resonator which resonates with the transmission-side coil, and an inverter for feeding power to the transmission-side resonator. The inductance value of the transmission-side coil and/or the capacitance value of the transmission-side resonator is set so that the frequency range in which the phase difference of a primary-side current flowing through the transmission unit relative to a primary-side voltage applied to the transmission unit is zero or above is wider than when the inductance value of the reception-side coil are equal to each other as are the capacitance value of the reception-side resonator and the capacitance value of the transmission-side resonator.
