Abstract

PURPOSE:To secure such as constitution for a switch circuit utilizing an optical combination that it emits light even if the current flows in from either the forward or backward direction as well as to give the circuit a self-support action. Thus, the dispersion of the conduction spots due to the uneven porperty can be reduced.
