Abstract: Mit dem Verfahren läßt sich bei geringem Rechenaufwand eine Achsbewegung, insbesondere in Form einer Pendelbewegung einer numerisch gesteuerten Achse durchführen. Dazu wird das Pendelprofil in die Zeitintervalle (tn-1,tn) unterteilt, in denen unterschiedliche Bewegungsvorgänge (Beschleunigung, keine oder konstante Geschwindigkeit) stattfinden. Bei jedem Systemtakt wird geprüft, in welchem Zeitintervall (tn-1,tn) die Summe der bereits ausgegebenen Systemtakte (iNT) liegt, so daß mit der entsprechenden, präparativ bestimmten, Weg-Zeit-Gleichung (Sn(t)) die von der Steuerung auszugebenden Wegabschnitte berechnet und an die Bewegungsvorrichtung der Achse ausgegeben werden können. Eine Änderung der Bahngeschwindigkeit durch eine Override-Vorgabe kann im Feininterpolator durch Multiplikation der Systemtakte (T) mit einem konstanten Faktor (f) bewirkt werden. <IMAGE> <IMAGE>

Abstract: The materials which have been washed and which are possibly heated from the washing process are subjected to a vacuum shock in a hermetically sealed chamber (11) before the establishment of a drying vacuum. This shock is produced by bringing an underpressure vessel (72) serving as vacuum accumulator into open connection with the chamber (11). As a result, the drying of the materials which have been washed can generally be accelerated considerably and washed materials which are difficult to dry and which it has so far only been possible to dry in a justifiable time using organic solvents can from now on be dried, using water mixed with detergents also, in justifiable times and consequently the use of organic solvents can be limited or avoided. <IMAGE>

Abstract: The present invention relates to a process for preparing benzo[c]phenanthridinium derivatives of the general formula A:
       
 wherein M and N individually represent a hydroxyl or lower alkoxy group, or M and N simultaneously represent a hydrogen atom or together form a methylenedioxy group, X⁻ represents an acid residue or a hydrogen acid residue, and R represents a lower alkyl group. This process has good reproducibility and may be effected under moderate conditions, and therefore the process is practically useful. Also, it has been found that certain novel benzo[c]phenanthridinium derivatives, prepared by the present process, have not only an antitumor activity but also an inhibition activity on blood platelet aggregation. In addition, hydrogen salts of the present compounds have an enhanced stability, which is an advantage in formulating into phamaceutical preparations.

Patent EP-0469681-A1 (EP)
Inventor: THIJS PETRUS JOHANNES ADRIANUS
IPC: H01S5/50
Filed: 1991-07-29
Abstract: 5 n7 The invention relates to an optical amplifier with a semiconductor body comprising a layer structure grown on a substrate (1), with an active layer (4) between two cladding layers (2,5), a strip-shaped amplification region being bounded by two end faces (7,8) of low reflection which form the input and output faces for the radiation to be amplified. The active layer (4) comprises a number of quantum well (QW) layers with direct band transition, and separated by barrier layers of a different semiconductor material, a first portion of which QW layers is under tensile stress. Such amplifiers are used inter alia in optical glass fibre communication systems. 
     The known amplifier is owing to the tensile stress, less sensitive to polarization but the amplification can not be obtained at a minimal current. 
     According to the invention, another portion of the layers forming part of the active layer is under compressive stress. Owing to the compressive stress present locally in the amplification region, the TE-mode is more strongly amplified there than the TM-mode, while in the tensile portion of the amplification region the TM-mode is more strongly amplified than the TE-mode. This enables realisation of a polarization insensitive amplifier with higher stress and thus with a large amplification at a relatively low current. 
     In one embodiment, both portions of QW layers are within one stack of layers containing the amplification region. In another embodiment both portions are positioned in different stacks that are located next to each other each adjoining a different endzone of the amplification region. In the latter, independent adjustment of the TE and TM amplification profiles is possible.

Abstract: In a marking system a pattern of marks present in a mask (30) is transferred to the surface (51) of an object (50) by causing radiation to act on the surface (51) via the mask (30). By adapting the shape and the surface of the cross-section of the radiation beam to the pattern to be shown, the pattern is irradiated at a high intensity while the amount of radiation falling outside the pattern is reduced. This is achieved by adapting the cross-section of the beam by means of an exchangeable optical guide and/or cylindrical lenses (21, 22) and/or by stepwise scanning the mask (30) in one or two directions by means of a scanning system (23, 24) while the irradiated parts (I 1  ,..., In) overlap each other to a considerable extent.
