Title: Procédé d'alignement optique de motifs dans deux plans rapprochés et dispositif d'alignement mettant en oeuvre un tel procédé
Inventor: FAY BERNARD
IPC: G02B27/42
Filed: 1979-09-05
Abstract: L'invention se rapporte à l'alignement de motifs dans deux plans rapprochés, l'un (masque) portant un motif à reproduire sur le deuxième (échantillon). L'invention a pour objet un procédé d'alignement optique de ces deux plans utilisant un couple de repères formés d'une lentille à zones de Fresnel linéaires (4), inscrite sur le masque (1), et d'un réseau réflecteur (3), de largeur convenable inscrit sur l'échantillon (2). L'éclairement par un faisceau de lumière monochromatique parallèle, de la lentille à zones de Fresnel produit sur l'échantillon une tache d'éclairement sensiblement rectangulaire qui lorsqu'elle est amenée en coïncidence avec le trait inscrit sur l'échantillon est réfléchie ou transmise, et fournit un maximum ou un minimum d'intensité détectée, suivant que le trait est plus réflecteur ou moins réflecteur que le reste de l'échantillon. L'invention a également pour objet le dispositif d'alignement optique mettant en oeuvre ce procédé. L'invention s'applique à l'alignement des masques à rayons X lithographiques ou des photomasques par rapport aux échantillons sur lesquels doit être effectuée la reproduction.

Abstract: Radio apparatus and in particular VHF transmitter and receiver apparatus for aeronautical use comprises a frequency synthesiser (17) which is able to generate any desired frequency within the range of the radio and a number of frequency channel selection devices. These selection devices include a channel tuning switch (11, 11') which is arranged on the front panel of the apparatus and which can be adjusted to select any desired channel within the frequency range of the radio and a number of channel selectors (12, 12'; 13, 13'; 14, 14') which can be preset to call up certain fixed channels as desired. A changeover switch (16a) at the front panel of the apparatus makes it possible to select any one of the channel selectors (12, 12'; 13, 13'; 14, 14') or the channel tuning switch (11, 11'). All the channel tuning devices are of similar construction and are mechanical stepping switches but the adjacent devices for the fixed channel selectors can only be actuated by means of tools. The selected channel is indicated on a liquid crystal display (18).

Abstract: An anhydride of a carboxybenzene is esterified in solution by a fluorinated alcohol, using N-methylpyrrolidone solvent. In particular, pyromellitic dianhydride in N-Methylpyrrolidone solvent is esterified to the diester/diacid by 2-(n-perfluoroalkyl)-ethanols having six to twelve carbon atoms in the perfluoroalkyl groups, and the reaction mixture containing the dissolved diester/diacid is admixed with an oxirane compound of the group ethylene oxide, epichlorohydrin and glycidol whereby the carboxyl groups are esterified in the N-methylpyrrolidone solvent by reaction with oxirane groups.

Abstract: A bridged transformerless power amplifier comprises main (10, 12) and inverse (18, 20) amplifier units having the same structure but producing outputs which are inverted relative to each other. A low-impedance load (28) is directly connected between the output ports of the main and inverse amplifier units. A first operation control circuit (SWO, SW3, SW4) activates only the main amplifier unit after the power switch is turned on, and a second operation control circuit (SW5) maintains the output port of the inverse amplifier unit in a floating state for a predetermined period of time after the activation of the main amplifier unit has begun. Hence, the power amplifier produces no pop noise when the power supply is switched on.

Abstract: The invention relates to an expanding means for removable fastening in a cylindric hole, consisting of an elastic cylinder, which is caused by axial contraction to expand and with the outer surface to engage with the cylindric hole, which cylinder is formed with a plurality of bars, which extends substantially in the axial direction of the cylinder. It is a known problem that, when the expanding means is located within a hole in the form of a cylinder, problems may arise in carrying out the expanding proper of the expanding means, because it is difficult for the operator to control by a tool or the like the expanding proper of the expanding means. This problem is overcome in that the bars (7) extend from grooves (8) running in the direction of the bars in the outer surface of the cylinder (1) and outward outside the outer surface.

Abstract: For the recording of local boundary-layer flow-line directions in liquid media by means of a photographic layer, (a) small reagent depots or deposits, with a volume of about 0.2 mm3, of a water-soluble substance reactive to silver ions ("chemical flow line indicators") are applied in raster fashion to the surface which is to be exposed to the flow and which surface is previously coated with a dry or swelled photographic sheet film, (b) the reagent deposits are covered with an inert layer which is soluble in the liquid flow medium, (c) the surface so prepared is exposed to the flow of an aqueous flow medium, and (d) the film is developed according to conventional means. The reagent deposits, which may be present as a paste, can contain a precipitation agent for silver ions. The deposits can be applied as a dot raster to the surface which is to be exposed to the flow (and which is coated with a photographic film) by means of screen printing or by means of a hole raster template. The method permits in particular the determination over a surface of the local distribution of the flow direction of flow boundary layers.
