Patent EP-0276395-B1 (EP)
IPC: G01D5/38
Filed: 1987-11-17
Granted: 1991-09-11
Abstract: In a photoelectric measuring apparatus as shown, for example, in Figure 3, relative movements between a diffraction grating (G') and a substrate (S') are measured. The radiation emitted by a semiconductor laser (L') integrated on the substrate (S') is directed via a waveguide lens (WL') and an output grating (AG') to the diffraction grating (G') where it is diffracted and returned to the substrate (S'). The diffracted part-beams (+m', -m') are fed by input elements (+H', -H'), which have input gratings (+HG', -HG'), by means of optical waveguides (+LWL', -LWL') into a coupler (TBJ') where they are brought to interference. From the coupler (TBJ'), they are conducted via optical waveguides, not designated in detail, to detectors (+D', D', -D') which convert them into electrical signals which are phase shifted with respect to one another. The electrical signals can be processed in an evaluating circuit not shown - which is also integrated - and can be displayed. 
<??>All elements from semiconductor laser (L') to the detectors (+D', D', -D') are combined in the form of an integrated optical circuit on the substrate (S').

Abstract: Un décomposeur de faisceau d'ouverture comprend un miroir intercepteur (7) positionné à un plan d'image d'ouverture éloigné de tout foyer, de sorte à dévier la moitié de l'énergie dans un faisceau d'énergie de rayonnement incidente. Le plan d'image d'ouverture correspond à un arrêt d'ouverture et la moitié d'un faisceau incident d'énergie rayonnante est perdue au niveau du plan d'image d'ouverture. L'énergie restante alimente l'entrée (8a) d'un système optique (9, 11). L'énergie rayonnante provenant de la sortie du système optique atteint un plan d'image correspondant au plan d'image d'ouverture. Si le système optique concentre l'énergie rayonnante dans un nombre impair de foyers (6, 10, 12), l'image formée au niveau du plan d'image d'ouverture subit une inversion symétrique spéculaire. L'énergie qui était retenue dans le système optique pendant le premier passage à travers le plan d'image d'ouverture (8a) remplit l'autre moitié du plan d'image d'ouverture (8b), de sorte que l'énergie rayonnante retournant à travers le système optique peut être séparée dans l'espace, à partir de l'énergie rayonnante incidente sans perte d'énergie ou perte d'informations d'image supplémentaire, ces informations dérivant d'un foyer intermédiaire.

Abstract: The invention relates to a device and a process for reducing the spatter effect when welding and for improving the welding work, particularly in the case of semi-automatic short-circuit arc welding using a direct-current supply. The welding current flows as a function of the arc voltage while the welding wire is fed towards the workpiece from the holder, the welding wire being subjected to a series of welding cycles. Each welding cycle comprises an arc phase and a short-circuit phase. In the case of this kind of welding, the invention makes provision for the supply of a predetermined amount of energy to the welding wire during the arc phase in each welding cycle, the said amount of energy exceeding the amount of energy, whose energy level is known, which is required to melt a certain volume of metal at the end of the welding wire into a coherent globule (droplet) of molten metal. This constant energy is divided between the resistance heating of the free end of welding wire projecting beyond the welding-wire holder and the anode heating which is effected by the arc in the arc phase of the welding cycle. <IMAGE>

Abstract: An antenna system and technique for laminating a dielectric substrate (14) to an antenna housing (12) which prevents separation of the dielectric substrate (14) from the housing (12). This is accomplished by confining an antenna assembly (10) inside a laminating fixture (24). Heat is then applied to the fixture (24). This causes the dielectric substrate (14) to become somewhat plastic and also to expand. This expansion results in great pressure being exerted between the dielectric (14) and the housing (12). When the assembly is allowed to cool, the dielectric (14) adheres to the housing (12). This prevents separation of the housing (12) from the dielectric (14). The result is an antenna assembly (10) which can withstand large temperature extremes without causing an air gap between the dielectric (14) and the housing (12) which would distort the electrical signal transmitted or received by the antenna.
