Abstract: An apparatus and method for inspecting X-ray and corpuscular beam, e.g., electron or ion beam, lithography masks for defects. The apparatus includes a stage to support the mask in the path of a corpuscular inspection beam projected from a beam source above the stage, an emitter surface below the stage for emitting secondary radiation resulting from the impingement of the inspection beam that has passed through the mask onto the emitter surface, a detector arranged to receive the secondary radiation to generate image signals corresponding to this secondary radiation, and an image storage device to receive and store the image signals. The stage is moved in a stepwise fashion to bring individual mask fields that can be scanned by the beam in a single step into the beam path until all of the fields of a given mask have been scanned. The image signal of the actual mask is compared to a stored reference to detect defects which may also be repaired by the same apparatus according to preferred embodiments.

Abstract: A shock wave source for an extracorporeal lithotripsy system has a number of electro-acoustic transducers arranged in a concave surface, each transducer having an acoustic axis, and the shock wave source having an acoustic axis. The transducers are each pivotally mounted, and a common adjusting element is provided which pivots each of the transducers so that their acoustic axes intersect at a focus, which lies on the acoustic axis of the shock wave source. The common element also permits adjustment of the location of the focus along the shock wave source acoustic axis so as to be more distal or more proximate relative to the shock wave source.

Abstract: The increasingly high standards of consistency and uniformity demanded of cold feed rubber extruders are met by providing notches in the flights of the screw at least in the feed-inlet of the extruder. The notches are at a lead-angle greater than that of the extruder screw flights, so to pull the rubber and advance it positively. Throttling means are used to adjust the amount of squash-back and there is an independently variable-speed drive for a feed roller in the feed inlet.
