すことは不可能でめり九。Such conventional trimming techniques are unidirectional, meaning that either the element to be adjusted or the insertion of the circuit can be opened only once, and cannot be returned to the previous state if the situation or state changes. It's impossible and impossible.
本発明の目的は調節後光の状態に復帰することの可能な
調節すべき素子又は装置に接続する接続手段を得ること
にある。The object of the invention is to provide a connection means for connecting the element or device to be regulated, which is capable of returning to the light state after conditioning.

3 are connected in parallel and the resistance value of the polysilicon resistor 13 is sufficiently low, a short circuit occurs between terminals A and B. Furthermore, when the wrinkled silicon resistor 13 is melted and disconnected by external power, the element or circuit 11 to be adjusted returns to the inserted state again. External power is supplied through the external power application terminal 14.
