Abstract: A photographic processing apparatus comprising two or more chambers having baths for processing photographic material and having at least one immersion roller in each bath for immersing and conveying the photographic material. The immersion roller may be driven by a magnetic coupling arrangement.

Abstract: A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.

Abstract: An illumination apparatus is disclosed which is suitable for use in a projection/exposure system for projecting an image of a circuit pattern of a reticle on a semiconductor wafer through a projection lens. The illumination apparatus includes an excimer laser for emitting a pulsed laser beam, an optical system for illuminating the reticle with a plurality of laser pulses emitted from the excimer laser so that laser pulses having passed through the reticle impinge on the semiconductor wafer in different directions through the projection lens, and a light intensity control device for controlling the light intensity of each of the laser pulses so that the laser pulses equally contribute to the reaction of a light sensitive material which is provided on the semiconductor wafer, with light.

Abstract: Selecting of particular image lines for composition of range image such that a composition and evaluation of range image is possible in real time actually corresponds to the imaging of a TV or video camera. The image field is scanned column by column and the contents of the column (all lines) are read in parallel. After digitizing the content of the column, a selection logic selects a particular imaging dot within each of the columns. Using the principles of triangulation, the line position of the dot selected is identified by a multibit binary data word is vertical position in representation of the distance from the camera or the light strip source.
