Abstract: A multi-layer component (1) is specified, comprising a main body (2) with an external contact (3) arranged thereon, a further contact (5) for electrically contacting the multi-layer component (1), and a connecting element (4) for connecting the external contact (3) and the further contact (5), wherein the connecting element (4) is embodied in such a way that a decoupling of mechanical stresses that occur in the further contact (5) from the external contact (3) is brought about.

Abstract: The invention relates to an actuator unit, which comprises a piezoactuator (1) having a first end face (14?) and a second end face (13?). The actuator unit further comprises a sleeve (9) for accommodating the piezoactuator (1), wherein the sleeve (9) has a first end face (14) and a second end face (13). The actuator unit further comprises a potting compound (11) which surrounds the piezoactuator (1). The piezoactuator (1) and the potting compound (11) are introduced into the sleeve (9). The potting compound (11) extends no further than the first end face (14?) of the piezoactuator (1). The invention further relates to a method for manufacturing an actuator unit and a sleeve for accommodating a piezoactuator.

Abstract: The invention relates to a method for producing an actuator unit comprising a piezoactuator (1), a sleeve (9) having a first end face (14) and a second end face (13), and a potting compound (11). The method comprises: inserting the piezoactuator (1) into the sleeve (9), wherein the piezoactuator is inserted into the sleeve (9) from the side of the sleeve (9) having the first end face (14); arranging a filling opening of a filling element (15) in an axial position near the axial position of the second end face (13) of the sleeve (9); filling a hollow space between the inner side of the sleeve (9) and the piezoactuator (1) with the potting compound (11) via the filling opening of the filling element (15), such that the potting compound (11) extends maximally to a first end face (14?) of the piezoactuator (1). The invention further relates to a sleeve (9) for receiving a piezoactuator (1).

Abstract: A device for holding components during electrode application includes two rigid plates having openings formed therein. An elastic material lines the openings in the plates and defines free spaces in the elastic material for receiving components.

Abstract: A PTC-resistor which is a temperature dependent electrical thermistor of semiconductor ferro-electric ceramic which is provided with power leads and serves as a sensor element is directly fused into glass. The power leads are welded to metal coatings formed on the PTC-resistor which are stable at the temperature occurring when the PTC-resistor is fused. The metal coatings are made of aluminum which are formed by aluminum silk screened metallizations which have a thickness of 50 .mu.m or more.
