IPC: H01Q3/04
Filed: 1978-12-11
Abstract: PURPOSE:To obtain an economical radar reflector by giving non-directivity to reflecting characteristics by turning a radio reflector. CONSTITUTION:Two corner type radar reflectors, obtained by combining flat plates with a metal surface crossing at right angles, are symmetrically joined together back to back and at their center, a vertical rotation axis is provided to obtain right-angled equilateral triangle A and right-angled equilateral fan shape B. The rotation axis is pivoted on a bearing and connected to separately-provided power or turned by wind force. Since bodies in those shapes form a two-blade a windmill, rotations are easily realized by even a gentle wind. In addition, spherical dielectric radar reflector D of strong reflecting characteristics provided with a rotation axis is also recommendable. Consequently, the effect similar to the radial arrangement of an infinite number of fixed radar reflectors can be displayed and easy and economical manufacture is realized.

IPC: G21C21/02
Filed: 1995-06-22
Abstract: PURPOSE: To produce a mixed oxide fuel for nuclear reactor from plutonium of weapon regulation in safety by inverting metal plutonium into plutonium powder at a remote place. CONSTITUTION: Plutonium is inverted into plutonium powder at a place remote from a fuel production facility. The plutonium powder is compacted and fired to produce a high dencity plutonia pellet being transported to the fuel production facility. Since the high density plutonium is not dissolved easily, it is difficult to separate plutonium therefrom and thereby it provides a safety means for transportation. In the fuel production facility, a plutonium pellet is crushed to produce plutonia powder which is then dieved to separate micro particles. The micro particles are admixed with urania to prepare a mixed oxide powder and a fuel pellet is produced by a standard technology.
