Abstract: A coil unit includes a coil formed of a conducting wire arranged on a first plane and laid side by side with itself in an inside-outside direction with a coil axis normal to the first plane as the center, and a plurality of magnetic plates arranged on a second plane which is along and adjacent to the first plane. A gap which is formed by the magnetic plates and traverses the inside-outside direction of the coil is located near an edge portion of the coil in the inside-outside direction.

Abstract: A ground-side coil unit is provided with: a magnetic material plate disposed adjacent to a power transmission coil that transmits electric power to a power reception coil in a wireless manner; and a first filter coil disposed facing the power transmission coil with the magnetic material plate interposed therebetween. The first filter coil is disposed in a position where a magnetic flux generated by the first filter coil cancels out a magnetic flux generated by the power transmission coil in the magnetic material plate.

Abstract: In an electric rotary machine of an axial gap type, at least one rotor including a rotor coreis provided, at least one stator is provided the at least one stator facing one surface of the at least one rotor with an axial gap therebetween, and a plurality of magnet groups is provided, each of the magnet groups comprising a plurality of magnets having the same polarities and being arranged in the rotor core to be mutually faced with each other in a radial direction of the rotor.

Abstract: An axial gap motor may benefit from a reduction of axial force on the rotor, which may reduce load on the rotor and bearings and reduce the vibration on the surface of the rotor. An air gap is positioned on the stator facing the rotor, and an auxiliary yoke is positioned facing the air gap on the other side of the rotor. Magnetic flux circulates from the rotor and the axial force ? is applied to the rotor when the magnetic flux passes by the air gap surface on the stator side of the rotor. Axial force ? is applied to the rotor when the magnetic flux passes by the air gap surface on the auxiliary yoke side of the rotor. Axial force ? is opposite, or reverse, of axial force ? and reduces axial force ? so axial force ? reduces the load on the rotor and bearings.

Abstract: An active metal bed provided with a filter unit of sintered metal having a wide surface in the horizontal direction, enclosing an active metal powder running a reversible hydrogenation reaction therein and, which is single or plural combined in series, a heater attached thereto and an airtight container housing them, and characterized by, at the time of absorbing hydrogen isotope gas, contacting or flowing the gas to the active metal through the filter, while preventing the scattering of active metal powder, to obtain a large hydrogen absorption velocity by a wide gas contacting area and a decreased pressure loss at the time of gas flowing, and characterized by, at the time of releasing hydrogen isotope gas, preventing the overheating of air tight container and the permeating of hydrogen thereby while heating only the filter unit by the heater.

Abstract: The present invention is concerned with a process for recovering tritium from tritiated water wherein a gas stream containing tritiated water steam is conducted into an electrolytic cell within which is disposed an oxygen ion conductive solid electrolytic membrane having a cathode and an anode disposed upon the opposite surfaces thereof. As a result of the electrolysis process, tritium gas is collected from the cathode side of the electrolytic cell, while oxygen gas is collected from the anode side of the electrolytic cell.
