Abstract: The locking movement and/or the unlocking movement of a bimetallic drive of an electrothermally-controlled locking apparatus, for example for household-device doors, is or are driven by a separate bimetal member (10, 11) over only a first segment of its movement path. In the process, energy is supplied to the energy store (28) of a tipping over-center device until a dead-center position is attained, the energy being released as a moving drive for the remaining segment of the movement path when the dead-center position is exceeded, thereby cutting off the bimetal drive and stabilizing the locking member (2) in its end position.

Abstract: A variable attenuation type optical power attenuator permits easier adjustment of the amount of optical attenuation and it is able to securely maintained an adjusted or set amount of attenuation. The variable attenuation type optical power attenuator employs a fixed ferrule and a rotating ferrule that have their end surfaces polished, together with the central optical fibers thereof, to be formed into inclined end surfaces. An alignment sleeve supports the fixed and rotating ferrules with optical fibers so that the distal ends thereof are opposed and that the ferrules may be relatively rotated, thus making up an assembly composed of a pair of ferrules. The assembly of the paired ferrules is supported in a rotating housing by a fixed housing. The variable attenuation type optical power attenuator adjusts the distance between the optical fiber end of the fixed ferrule and that of the rotating ferrule by rotating the rotating housing to change the relative rotational angle in relation to the fixed housing.
