The invention is directed to an arrangement for generating a pulsed laser beam with high average output, in particular for generating a hot plasma which emits extreme ultraviolet (EUV) radiation. It is the object of the invention to find a novel possibility for generating a laser beam with a high repetition rate and average output which allows the repetition frequency and, therefore, the output of the laser system to be increased by connecting together a plurality of individual lasers having limited repetition rate without degradation of the beam quality on the target compared to that of an individual laser. This object is met, according to the invention, in that an oriented mirror surface is associated with each individual laser in such a way that a beam bundle which is emitted by each individual laser so as to be offset with respect to time and which is reflected at the mirror surface is coupled into a common beam path, and laser pulses in the common beam path are directed to a target one after the other in a regular, defined pulse sequence, and, with a continuously dynamic mirror movement for coupling the laser pulses into the common beam path, optical means are provided in the common beam path for compensating the directional change caused by the mirror movement.

An inline stacker receives a shingled stream of printed sheet products from a printing press, or finishing equipment, at line speed. A sheet counter at an infeed conveyor section controls the operation of the inline stacker. The infeed conveyor can pivot to a divert position where it feeds the stream to a bi-directional conveyor. A following gap generator section of the stacker has two conveyors with opposed movable ends that are physically separated in the conveying direction by a small gap. The infeed conveyor and gap generator conveyor sections carry the stream at a substantially constant speed, which can be the line speed. To produce a gap in the shingled stream that defines a bundle size, the movable conveyor ends defining the gap between the conveyor gap generator sections move downstream in unison at the speed of the upstream conveyor. At the same time, the speed of the downstream conveyor is briefly increased. The movable ends and the increased conveyor speed then return to their initial status. Stacks of a predetermined size are collected on a forked elevator with mirror movement side walls and other product movement and position controls. Ball-screw-driven and cam-driven side joggers (at the infeed) align the stack and infeed stream laterally. The ball screw jogger, under control of a central controller and an associated servo motor rotates continuously in one direction to open the side walls in response to a sensed jam. The stacker is portable and mechanized for side lay adjustment to align with the press or finishing equipment.

The invention belongs to the technical field of precise machining and provides a finishing device and method for a symmetrical double-cone-surface grinding wheel. To solve the problem of high-precision finishing of the symmetrical double-cone-surface grinding wheel, a method that mirror movement of diamond pen linear movement is formed through turning-over by 180 degrees is provided, and high-precision finishing of the symmetrical wheel double cone surfaces is realized. The finishing device for the symmetrical double-cone-surface grinding wheel comprises a diamond pen grinding wheel finisher,a flange bearing, a flange pin shaft, a finisher holder, a micrmeter head bracket, a ball head micrmeter head and a 180-degree turning-over and positioning device. The diamond pen finisher can rotatearound the finisher holder, and adjustment of any taper angle can be realized. Above all, the finishing device for the symmetrical double-cone-surface grinding wheel has only one guide rail system, has the advantages of being simple in structure, high in linear movement and turning-over movement precision and adjustable in taper angle and the like and has good market application prospect and popularization values.

A surgical apparatus for use in endoscopic surgery having a user interface operatively coupled to an articulating tool assembly via an elongate tubular member. Movement at the articulating tool mirrors movement at the user interface thereby providing intuitive operation of the surgical apparatus. The apparatus is configured such that the range of motion of the articulating tool assembly emulates the range of motion of the human wrist.

Solar power station of the Fresnel type comprising a vaporizing receiver (2) and a superheating receiver (4) arranged in parallel, and mirrors (8.1, 8.2) comprising first mirrors (8.1) focused on the vaporizing receiver (2) during nominal operation and the second mirrors (8.2) being focused on the superheating receiver (4) in nominal operation, mirror movement means, in which power station the superheating receiver (4) is supplied with fluid in the form of steam by the vaporizing receiver (2), said power station also comprising means for controlling the movement means, and means for measuring at least one operating parameter of the power station. The control means activate the movement means as a function of at least one operating parameter of the power station so that at least one mirror (8.1, 8.2) is focused onto a different receiver (2, 4) from the receiver on which it is focused in nominal operation.

System and method for synchronizing the low speed mirror movement of a mirror display system with incoming frame or video signals, and synchronizing buffered lines of video data to the independently oscillating scanning mirror. According to one embodiment of the invention, the peak portions of the low speed cyclic drive signal are synchronized with the incoming frames of video by compressing or expanding the peak portion or turn around portion so that each video frame begins at the same location on the display screen. The actual position of the high frequency mirror is determined by sensors and a “trigger” signal is generated to distribute the signals for each scan line such that the scan lines are properly positioned on the display.
