摘要： An electronic controller having a detachably mounted front panel unit on which display devices and control elements are arranged is disclosed. By means of the control elements, the process variables and the control parameters are changed incrementally. Values of the control parameter, process variables, and the selected control parameter are indicated by the display devices. To provide a compact, independent front panel unit which can be removed from the main housing of the controller for protection against unauthorized operation, the front panel unit is provided with a slave microprocessor which is connected via a plug-in connector to a master microprocessor in the main housing. Because the master microprocessor operates independently of the front panel mounted slave microprocessor, the front panel unit can be removed without affecting the operation of the controller.

摘要： An improved method for pictorially displaying a diffraction image in a transmission-type, scanning, corpuscular-beam microscope in which a beam detector is scanned by a diffraction image moved by a deflection system in line-raster fashion in a first, predetermined direction over the beam detector. The beam detector generates an output signal for controlling the brightness of a television monitor which displays the diffraction image. The improvement of the invention comprises the step of additionally exciting the deflection system so as to move the diffraction image in another, second direction over the beam detector which is perpendicular to the first, predetermined direction so that a predetermined area of the diffraction image which includes at least part of the cross-section of the maximum intensity of the null reflex of the beam is excluded during scanning of the beam detector and the diffraction image displayed by the television monitor is blanked in an area corresponding to the cross-section of the diffraction image which is excluded during scanning.

摘要： A device for setting an electric command variable comprising parallel circuit branches for the coarse and fine adjustment of the variable is disclosed. In particular, the fine and coarse adjustment branches each include a digital bi-directional counter and a digital-analog converter. Upon exceeding the limits of the conversion range of the digital-to-analog converter of the fine branch, the counter therein is adjusted to a value which corresponds to a middle setting of its associated converter. To prevent the latter adjustment from causing a variation of the analog command variable, a corresponding correction of the counter in the coarse branch is then made. The present device has particular application in the setting of the energizing currents in magnetic lenses of an electron microscope.

摘要： A method and apparatus for focusing the objective lens of a scanning transmission-type corpuscular-beam microscope. In the method, the beam of the microscope is deflected by a deflection system excited in sawtooth fashion and generates a raster consisting of parallel lines on the specimen to be examined. The microscope includes a beam radiation detector disposed behind the specimen along the beam path which generates an output signal which controls the brightness of a picture tube monitor operated synchronously with the raster. The improvement of the invention comprises the steps of measuring, during the exposure of a specimen point, partial beam radiation intensities in the cone of the beam at two points disposed symmetrical with respect to the longitudinal axis of the beam cone by means of the detector, the effective input area of the detector being smaller than the cross-sectional area of the cone of the beam at the same height in the microscope. The lens current of the objective lens is then adjusted so that the output signals generated by the detector are equal for the beam radiation measurements at the two points. An apparatus for automatically focusing the objective lens in the foregoing manner is also disclosed.
