Abstract: A torque sensor assembly comprises at least a pair of permanent magnets axially spaced at a predetermined distance and integrally fixed to a driving shaft, and at least a pair of Wiegand Effect elements arranged in magnetic coupling relationship with the respective magnets for detecting a phase difference between pulses occuring in each pickup coil of the Wiegand Effect elements during rotation of the shaft.

Abstract: A pressure sensor is formed by separating two chambers by a movable member to which is coupled an amorphous metal material. The amorphous metal material is anchored at its other end to be subjected to differing amounts of stress in accordance with movement of the movable member due to pressure changes. The tensile stress applied to the amorphous member is electrically detected, e.g. by detecting the impedance characteristics of an electrical coil adjacent the amorphous member.

Abstract: An adaptor for an auto strobo unit comprises a trigger signal feed circuit for supplying a trigger signal to a flashlight trigger circuit of said auto strobo unit in response to the closure of a synchro contact of an automatic exposure controlled camera, a polarity inverter for inverting the polarity of an illumination interrupt signal supplied by a photometric control circuit of the camera to a polarity which is suitable to activate an illumination interrupt circuit of the auto strobo unit, an amplifier for amplifying an illumination interrupt signal to a given level, and circuit means for feeding the polarity inverter or the amplifier when the trigger signal feed circuit is operated. The adaptor enables an automatic exposure controlled camera to be combined with any kind of an auto strobo unit.
