The invention relates to a path andor position measuring device comprising a magnet and a sensor detecting the magnetic field intensity. The diode includes a stack of a first semiconductor region containing an impurity of a first conductivity type, a second semiconductor region containing an impurity of the first conductivity type lower in concentration than in the first semiconductor region, and a third semiconductor region containing an impurity of a second conductivity type. The trigger circuit is reset and enabled by a second signal in order to enable subsequent output of the first signal. An actuator is associated with the probe and is adapted to selectively position the probe with respect to an electrical contact on the microelectronic component. The binders can be used in preparing coatings, coating materials, coating compositions, adhesives, printing inks, casting resins, dental compounds, sizes, photoresists, stereolithography systems, resins for composite materials and sealants.
