摘要： Conventional beam blanking system generate electron pulses having a minimum width of about 100 through 200 ps. Although a reduction of the pulse width to a few tens of picoseconds is fundamentally possible, the reduction of the probe current accompanying this would result to a considerable lengthening of the measuring times. In the invention a photo-cathode (PK) is charged by a pulsed laser beam (LA) which is attached to the column of an electron beam measuring instrument and the photo-electron source is stigmatically imaged onto the beam axis (OA1) using a focusing deflection unit (SFM). A sector field magnet is used as a focusing deflection unit (SFM).

摘要： An inductive component, for the formation of a magnetic circuit has at least one wire winding and at least one core with a ferromagnetic core material. The core comprises a gap and at least one further gap to interrupt the magnetic circuit. The inductive component is characterized in that the gaps each have a gap width of at least 1.0 mm. The core comprises two pieces, for example, which are arranged opposed to each other across the gaps and separated from each other by the gap width. The component is advantageously symmetrical with an essentially equal gap width for the gaps. A miniaturized inductive component is possible by the use of a hire winding made from high frequency braided wire and core material capable of accepting high frequencies, which has a high Q-factor even on a high power throughput and thus low electrical losses. In order to increase the Q-factor, the inductive component also has a cooling device for cooling the wire winding. The device is thus provided with a composite material with a thermally-conducting filler. The inductive component is used in a so-called electronic ballast (EVG) in the field of illumination.

摘要： A scanning microscope scans over the surface of a specimen to be tested in point-by-point fashion with a probe. The scan rate of the probe is controlled as dependent on a secondary electrical signal derived from the measuring point of the specimen surface and, thus, serves as a control signal to the output signal of a signal processing unit which is evaluated at a window discriminator or comparator. The output signal is supplied to a voltage controlled oscillator of the scan generator through an adjustable timer element. Simultaneously, the evaluated output signal is used for modulating the intensity of the write beam of a display means for controlling the intensity of the probe.

摘要： A method for representing logic changes of state occurring at a plurality of adjacent circuit nodes in an integrated circuit in the form of a logic image employs a pulsed electron probe which always scans a same path in the x-direction on the integrated circuit and the phase of the electron pulses comprising the pulsed electron probe is continuously shifted for each new scanning operation. The integrated circuit can be imaged up to the edge of a recording or field of view limit and it is only at this limit that the y-deflection of the pulsed electron probe is fixed. Very small spacings, such as those occurring between adjacent integrated circuit tracks, can thus be reliably imaged on the picture screen of the scanning electron microscope.

The inductive component is characterised in that the gaps each have a gap width of at least 1.0 mm. The core comprises two pieces, for example, which are arranged opposed to each other across the gaps (7, 8) and separated from each other by the gap width.

摘要： Evaluating method and apparatus for a test voltage by use of a bandwidth-limited evaluation circuits. For evaluation of a measured signal dependent on a variable parameter, an identification is first undertaken with a broad-band evaluation circuit to determine whether an interesting sub-region of the overall variation region of the parameter has been reached. When this is the case, then a reduction of the bandwidth of the evaluation circuit and a reduction of the variation rate of the parameter occurs in order to be able to evaluate with high sensitivity in the interesting sub-region.

摘要： A method and apparatus localize weak points within an electrical circuit. The electrical circuit is covered with a liquid crystal and is heated to a temperature just below the clearing point of the liquid crystal. The liquid crystal converts into its unordered condition given a temperature increase and leakage channel within the integrated circuit are completely localized. By irradiating a three-dimensional region, at least one current is induced in the region by generating electron-hole pairs within the electrical circuit, this at least one current causing a temperature increase at at least one weak point of the electrical circuit.

摘要： A method and apparatus for automatically and continually feeding workpieces, one after another, to a sewing machine. The continuous feeding is imparted to the workpiece by a plurality of connecting links which connect the trailing edge of one workpiece with the leading edge of the following workpiece at a point in front of the sewing instrumentalities. The workpiece that is being fed into and through the machine automatically draws the succeeding workpiece towards and through the machine due to the connecting link fastening these two together. Motion is imparted to the connecting links by the feed device associated with the sewing machine. The connecting links are guided through a predetermined path by a rail system which automatically returns the connecting link to a staging area after same has been released from the workpiece. A sewing machine fastens together the continguous ends of the workpieces and a cutter cuts the chain formed therebetween.
