Abstract: A particle-beam exposure apparatus (1) for irradiating a target (41) by means of a beam (2) of energetic electrically charged particles comprises: an illumination system (101) for generating and forming said particles into a directed beam (21); a pattern definition means (102) located after the illumination system for positioning a pattern of apertures transparent to the particles in the path of the directed beam, thus forming a patterned beam (22) emerging from the pattern definition means through the apertures; and a projection system (103) positioned after the pattern definition means (102) for projecting the patterned beam (22) onto a target (41) positioned after the projection system. The apparatus further comprises an acceleration/ deceleration means (32) containing an electric potential gradient which is oriented substantially parallel to the path of the structured beam and constant over at least a cross-section of the beam.

Abstract: A radar system is operated by controlling and thereby limiting the mean power of the transmitted signal in response to the mean power of the received signal thereby limiting the power to a predetermined power range. Preferably the power control or regulation is performed by varying the pulse repetition frequency and/or the pulse duration of the transmitter pulses. This method is well suited for operating a motor vehicle range warning system.

Abstract: A detachable insert connection arrangement adapted to be connected to a retaining channel having a slot-like opening between two retaining edges and method of connecting a component to a retaining channel. The connection arrangement includes a holder having a push-in part that includes a locking element. The push-in part is capable of being pushed into the retaining channel. A rotation pin is coupled to the locking element. The locking element is at least partially rotatable in two directions. A spring biases the locking element towards a locking position such that when the locking element is arranged in the retaining channel, the locking element bridges the slot and engages an inside of the two retaining edges. The locking element is movable, upon movement of the rotation pin against a biasing force of the spring, to a non-locking position, whereby the push-in part can be removed from the retaining channel.

Abstract: Disclosed is a uniquely identifiable identification system incorporated into an X-ray testing apparatus or into this system, so that each operator (6) can log onto the operating system only with his or her own individual identification (4, 4.1). The identification (4, 4.1) is read and optionally rewritten by a counterpart device (3, 3.1) of the identification system. Upon leaving the operating system, the operator (6) is automatically logged off by way of removing the identification device (4, 4.1), or by way of exiting from a defined local area (N) around the X-ray testing apparatus, and the operating system is then ready for access by another operator (6).

Abstract: A gas generator comprises an outflow chamber and a freeing element. The outflow chamber contains at least briefly gas under pressure, when the gas generator is activated and at least one outflow opening is arranged in a side wall of the outflow chamber. The freeing element is arranged non-displaceably in the outflow chamber and has a peripheral wall and a base wall. The peripheral wall extends along the side wall and closes at least one outflow opening before an activation of the gas generator. The base wall is connected with the peripheral wall. The freeing element is constructed so that on exceeding a predetermined gas pressure in the outflow chamber, the base wall turns inwards under partial plastic deformation of the peripheral wall and at least one hitherto concealed outflow opening is freed by the plastic deformation of the peripheral wall.

Abstract: An electrostatic corrector with a rectilinear optical axis has two corrective parts, which are arranged one behind the other along the optical axis and which have respective quadrupole fields and superimposed circular lens fields. The astigmatic intermediate image of one cross-section that is created by an axis point lies in one corrective part and the astigmatic intermediate image of the other cross-section, which is perpendicular to the first cross-section, lies in the other corrective part. An object of the invention is to eliminate the chromatic aberration of particle lenses. To achieve this, an electrostatic corrector is used, which includes two corrector units having similar instrumental construction, with each of the two corrector units having input and output sides on which two additional electrostatic quadrupoles are located. The two corrector units represent the axial paths in a telescopic manner in a 1:1 representation.

Abstract: An operating device for a vehicle, such as an airplane or a bus, includes a board that is adapted to carry electronic circuits, and at least two catch hooks for receiving the board between them. Each of the catch hooks has a contact portion for retaining the board and a base part for supporting the contact portion. The base parts of the catch hooks face each other, and the contact portions face away from each other. When the board is loaded, the catch hooks are pressed towards the respectively other catch hook which results in that the catch hooks lean more and more firmly against the board when force is induced onto the board.

Abstract: The invention relates to the embodiment of so-called panel loudspeakers working according to the bending wave principle. Said panels are generally formed by a panel (11), at least one driver (12) and a frame (13), the panel (11) being connected to the frame (13). In order to achieve appropriate bending wave induction in the panel (11), very complicated assessments must be made in order to determine the corresponding positioning areas (15) in which the driver (12) excites the panel (11) or is connected to the latter. Furthermore, the size of the panels (11) can change considerably depending on the application so that assessments must only be made repeatedly in the case of panels that can be easily modified. The invention aims at providing general positioning areas (15) for the driver (12) in or on the panels (11) so that no further assessments need to be carried out regarding the positioning area (15).
