The present invention provides methods, devices, and systems for in vivo treatment of cell proliferative disorders. The engine compartment has a first sidewall, a second sidewall and an upper cover. Materials are nonferrous and nonmagnetic so as to be magnetic resonance imaging safe, being substantially immune to strong magnetic fields and not introducing an electromagnetic interferencecompatibility hazard. A cutout is formed between the cover and the front face, the cutout being in either the cover or the front face which allows discharge of the printed material. The reflector is characterized in that the ends of the shade spokes that turned toward the linkage thereof extend beyond said linkage respectively and in that, due to the effect on said sections of the shade spokes extending beyond the linkage, said sections can be moved into the mounting position and back. min, and T2 represents a glass transition temperature thereof and Q2 represents a an endothermic quantity at a melting point thereof after melting after heated from \u221220\xb0 C.
