| Outline of Final Research Achievements |
We examined to draw a magnetic circuit on the substrate composed of a solid solution (gamma phase) by a laser beam. The paramagnetic solid solution was made by heating SUS XM27 ferritic stainless in nitrogen gas of 1 atm at 1200oC. Since the local heating by the laser beam turned the gamma phase back to the ferromagnetic alpha phase, application of this method to a magnetic circuit of magnetic attachments enabled to get attractive force as same as those of present products. We also examined possibility of the induction of biomedical tissue by a static magnetic field using the magnetic circuit. When endocapillary cells were exposed in the static magnetic field, the magnetic field tended to excite them with respect to length, area and number of branch of newborn blood vessels.
