A semiconductor component and a method for its production in semiconductor chip size, can have a semiconductor chip, which has external contacts of the semiconductor component that are arranged in the manner of a flip-chip on its active upper side. The semiconductor chip can be encapsulated by a plastic compound at least on its rear side and its side edges. The outer contacts, which can be arranged on external contact connecting areas, can project from the active upper side.

A locking arrangement for unfoldable solar generators which consist of several panels provides a lockable, partially-unfolded, intermediate position and a lockable, completely unfolded final position. In the partially-unfolded position, a panel is pivoted by 90.degree. so that a lock pin which is acted upon by a radially inwardly directed spring force and which, at first, slides on an outer section of a curve of a guiding contour, locks into an opening of a curved slot in a guiding element having the guiding contour. During the transition into the fully unfolded position, a plate cam, which had stopped at first, is rotated so that its driving groove can accommodate the lock pin which can now continue to slide on an inner section of the curve into the final locking position.

An unfolding joint for the panels of a solar generator is constructed for the partial and complete unfolding of the outer solar panel of the solar generator which is connected to the body of a spacecraft. The solar generator includes, in addition to the outer panel a pluraLity of inner panels. The unfolding is controlled by a closed cable loop in a positive manner, whereby primary and secondary hold down devices are provided for the outer panel and for the inner panels respectively. The unfolding joint includes two joint sections which are tiltably connected to each other and are tilting axis of the joint carries a rotatably mounted cable pulley. Two spring biased locking members are mounted in the joint section that is connected to the outer panel. Stop surfaces are provided in the second joint section and in the cable pulley for cooperation with the locking members. In the partially unfolded state both locking members cooperate to provide a formlocking of the unfolding joint. In the fully unfolded state the locking is accomplished by only one of the locking elements in the form of a locking lever. During the transition from the partially unfolded state into the fully unfolded state the other locking member in the form of a locking bolt provides a formlocking connection of the outer or second joint half with the cable pulley for the closed loop cable control.

A system for releasably securing support elements in a space vehicle wher a holding element extending through the support elements is pivotally mounted to a lever at the inner end thereof with a spring loaded release lever maintaining the outer end of the holding element in securing position. The inner end of the holding element is pivotally mounted to the lever at a point located eccentrically relative to the point of rotation of the lever and a releasable spring loaded piston operates upon severing of a blocking element to release the spring loaded piston to enable the lever to rotate to move the holding element so that the release lever engaging the outer end thereof may operate to release the holding engagement between the release lever and a support bushing whereupon the support elements will be released for movement. A limitation member is provided to limit the angle of movement of the release lever to 90.degree. when releasing the outer end of the holding element.

An articulation arrangement connects individual elements of a folding structure which consists of two or more individual elements and is configured to be unfolded and locked in an unfolded position and swivellably disposed on a central body. The arrangement comprises two hinge parts each rigidly fastened at one of two adjacent individual elements and swivellable about a common hinge axle, a slotted disk provided with a slot and forming part of one of the two hinge parts, a lever swivellably disposed on the other of the two hinge parts and provided with a pin. The pin is configured and arranged such that, before the unfolded position is completely reached, the pin slides on an edge of the slotted disk and, in the completely unfolded position at which locking occurs, the pin is engaged in the slot. For unlocking of the folding structure there are provided a rotatable cam plate with an edge curve of changing radius to disengage the pin and pulleys as well as driving and transmitting devices to rotate the cam plate and to transmit the rotation to the respective adjacent elements.
