Abstract: EXPOSURE AND CAMERA CONTROL                        ABSTRACT   An exposure and camera control system comprising a keyboard for providing input information relating to film parameters and camera type, a light to frequency convertor for providing signals having a frequency proportional to the intensity of light to be used in exposing the film, and a control operatively connected to the information providing keyboard and to the light to frequency convertor for determining the film exposure time and for providing signals for controlling film exposure to light and signals for controlling film transport when the exposure is complete.  The control includes a microprocessor, programmable memory, and input/output interface components.  A display operatively connected to the control provides visual display of information inputs to the control and of calculated quantities such as exposure time.  A printer operatively connected to the control provides a hard copy record of the displayed information.  A light detector operatively connected to the control includes a mirror normally positioned in the optical path for directing light to the light to frequency convertor, which mirror is moved out of the optical path before an exposure is made.  Sensors in the camera being controlled provide signals to the control indicative of film travel and presence of a new film roll in the camera.  The exposure and camera control has advantageous use with a microscope in apparatus for making photomicrographs.

Abstract: ABSTRACT            The pressure medium actuated valve (1) has a pressure medium inlet port (11), an outlet port (12) and a cylinder in which a piston (24) connected to a closure member (13) can slide.  The piston subdivides the cylinder (2) into a first piston space (21) and a second piston space (22).          Two relief conduits (44,45), each containing a control valve (441,451) are connected to the piston spaces (21,22) and extend to a pressure medium sink.   A first connecting conduit (41) containing a control valve (411) extends from the inlet port (11) to the first piston space (21), and a second connecting conduit (42) containing a control valve (421) extends from the inlet port (11) to the second piston space (22).   The second connecting conduit (42) has a nonreturn valve (422) through which pressure medium flows in the direction of the second piston space (22), a third connecting conduit (43) being provided between the first and second connecting conduits.          As a result, the closure member can be moved at two different speeds.         (Fig. 2a)

Abstract: ABSTRACT     Disclosed is a process for the production of a mask for use in X-ray lithography consisting of a frame, a carrier foil composed of metal which is clasped to the frame and is permeable to X-rays, and of masking structures which are arranged on the carrier foil and are impermeable to X-rays and which produce a desired pattern in an X-ray resist during a lithographic reproduction process.  The process comprises the steps of coat-ing a metal carrier plate which, after the production of the X-ray mask, serves to form the frame, with a layer of a further metal, depositing a 1-3 µm thick metal carrier foil by vapour deposition or sputtering on to the further metal layer, applying a 10-15 µm thick polymethyl methacrylate layer to the metal carrier foil, structuring the polymethyl methacrylate layer to form a stencil corresponding to the pattern of the mask, electro-lytically depositing a nickel layer to a thickness of 1-2 µm and then a gold layer to a thickness of 8-10 µm, on the surfaces of said carrier foil exposed through said stencil, etching a window in said carrier plate down to the further metal layer, the residual part of the carrier plate forming the frame, and finally structuring the further metal layer exposed in the window in a further etching step.

Abstract: ABSTRACT: Current-source arrangement.     A current-source arrangement supplying a current which increases directly proportionally to the supply voltage (VS) and which is suitable for operation with supply voltages above approximately 0.7 V, comprises a first resistor (R10 = R) in which a current (VS-VBE)/R flows, which current is supplied by a first transistor (T10) via a first current-mirror circuit (T11, T12) and a second current-mirror circuit (T13, T14). A second resis-tor (R2 = R) is arranged in parallel with the base-emitter junction of the input transistor (T11) of the first cur-rent-mirror circuit (T11, T12), through which second resistor (R2) a current VBE/R flows which is supplied by the first transistor (T10) via the collector-base inter-connection of the input transistor (T11). The total current flowing through the first transistor (T10) is then equal to VS/R. This current can be taken from the collector ter-minals (15A, 15B) of the transistors (T15A, T15B), whose base-emitter junctions are connected in parallel with the base-emitter junction of the first transistor (T10).
