An apparatus and method for non-invasive treatment in lieu of cosmetic surgery is disclosed. In this system, the control lever 52 has a locking position permitting the control lever to turn from the neutral position in a direction opposite from the slightly opening position A. In one aspect, the invention relates to a containment vessel having a heat receiving region and a heat transfer region such that a plurality of phase change materials are disposed therein and a sequence of solid, liquid and vapor phases are used to transfer heat from a source to a heat receiver of a power conversion unit. When the light intensity of ambient light is lower than a predetermined light intensity of the liquid crystal display device, the red light emitting diodes, the green light emitting diodes and the blue light emitting diodes of the backlight device are sequentially energized to emit lights at a predetermined time lag. The rotation joint has a dual rotation pin element having a center rotation axis and dual rotation elements configured to rotate about the center rotation axis.
