An image forming apparatus includes: a main body provided with a drive-force supplying part; a cartridge comprising a rotary body and a drive-force transmission part; and a moving member supporting the cartridge. Methods for the treatment of diseases and conditions of the peripheric system and the central nervous system are also disclosed. The audio-signal processing apparatus generates a harmonic-tone individually for each pure tone component, which includes complex tones and suppresses deterioration of the sound quality. At least a portion of the horizontal active region is oxidized to form an isolation region. Therefore once the flat panel display has been newly manufactured, it can be conveniently wrapped and transported at a reduced cost. More particularly, the disclosed invention employs a frame and pulleys to drive a wire loop cutting element.
