The electronic component, comprises an integrated circuit incorporating several separate functional blocks within a semiconductor substrate, and electrostatic discharge protection means. The method includes administering a TPO mimetic compound to a subject. By detecting a portion of the address pattern that is adjacent to the reading device, a position of the reading device can be determined. The toner supplying device includes a toner tank which stores toners discharged from the toner container, a toner carrying section which carries the toners stored in the toner tank in an obliquely upward direction, and a toner dropping route which causes the toners carried by the toner carrying section to drop into the developing device by toner own weight. In reproduction, the respective time scales of the respective data are commonized to thereby permit synchronization between a reproductive music performance and visual display.
