Title: Super unique motor
Inventor: SHIROYAMA YUSUKE
IPC: H02K1/27
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption of a super unique motor by arranging electromagnets on the outer periphery of a rotor, constituted by alternately arranging permanent magnets and aluminum sections. SOLUTION: A rotor is constituted by alternately arranging numerous aluminum sections and permanent magnets, so that the magnetic intensities of the magnets can gradually increase in the state of, for example, 100 Gauss, 200 Gauss, 300 Gauss, and electromagnets X are arranged on the outer periphery of the rotor. For energizing the electromagnets X, a switch is set within the range of 2,400-100 Gauss. When, for example, the 2,400-Gauss section of the rotor meets one electromagnetic pole S after the rotor has rotated clockwise, the electromagnet X is energized and an S-pole is generated in the electromagnet X. The S-pole repulses the S-pole of the rotor and, as a result, the rotor turns in the direction, shown by the arrow H. Around the 100-Gauss section of the rotor, the switch turns off, and the S-pole of the electromagnet X disappears.  After the S-pole has disappeared, the magnets of the rotor are repulsed by the cores of the electromagnets and the high-intensity section of the rotor is gradually pulled in, and the rotor continues to rotate in the direction H. By increasing the number of the electromagnets, a strong torque and rotation can be obtained.

Abstract: PURPOSE:To reduce pressure loss and increase heat transfer surface in a heat accumulator mesh for stirling engine by a method wherein a mesh formed by braiding  wires of approximately circular section is applied with a corrosive liquid in the direction of overlapping them to change the sectional shape thereof into an approximately elliptical shape. CONSTITUTION:Wires 1 of a stainless steel, etc. and having an approximately circular  section are braided into a mesh 2 by plain weaving or the like, and each one of the  mesh or a plurality of meshes placed one upon another are applied with a corrosiave  liquid, for example, nitric acid, which is allowed to flow down on them in the direction of overlapping. As a result, the postions of the mesh which give higher resistance  to flow of the liquid corrodes more rapidly so that the wires 1 are changed into wires  1' having an approximately elliptical section are brought into contact with adjacent  longitudinally extending wires 1' which overlap the former. Thereafter, the longitudinal direction of the mesh 2' which has been neutralized by a neutralizing agent and  washed with water is located in parallel with the direction of flow of a working gas.  Thus, its resistance to heat in the direction of flow of the gas can be maintained,  and no pressure loss occurs.
