Patent EP-0411797-A1 (EP)
Inventor: KOSTELAK ROBERT LOUIS JR
IPC: H01L21/331
Filed: 1990-07-20
Abstract: In order to reduce alignment errors arising in the fabrication of semiconductor integrated circuits using electron beam lithography, enhanced registration marks (142, 141)--(i.e., registration marks that are more easily and accurately detectable by the electron beam)--are formed at the edges (110, 111) of oxide layers (11), located at the surface of a silicon body, by means of forming metal silicide layers (14) having edges coincident with the edges (110, 111) of the oxide layers (11). Advantageously, the enhancing of the registration marks by forming the metal silicide is performed subsequent to any high temperature processing steps, whereby the integrity of the marks is maintained.

Abstract: The unaltered program is decomposed into a set of hierarchical parts, each part being associated with a task to be executed by the processor, then, in a read-only memory, is stored the executable code of each of the various latter parts in the hierarchy and the composition (AMX, AMR-AMB-AMV-AMR-AMB-AMV, AMY, AMPR-AMCH-...-AMRI) of each of the other parts, then, in a reprogrammable memory, are stored the memorisation addresses (AMX + 1, AMY +1) of the read-only memory whose contents are to be altered in response to an alteration of the program, as well as the corresponding alterations and, the memorised altered program is restored by successively reading the contents of the memorisation addresses of the read-only memory and by seeking, in the reprogrammable memory, for each memorisation address, a possible alteration of its contents so as to take account thereof. The invention is especially applicable in the domestic electrical field for selective and sequential control of a plurality of members of an automatic appliance like a washing machine, for example. <IMAGE>

Abstract: Le ressort de lancement directionnel décrit est utilisé avec un moteur synchrone à courant alternatif pour assurer la rotation de celui-ci dans la bonne direction. Le moteur synchrone à courant alternatif comprend un aimant circulaire tournant en syncrhonisme avec la fréquence du courant alternatif. L'aimant met en rotation un engrenage à vis sans fin fixé au centre sur sa face axiale. Cet engrenage à vis sans fin entraîne un second engrenage à vis sans fin disposé perpendiculaire au premier engrenage à vis sans fin. Le second engrenage à vis sans fin entraîne une série d'engrenages affichant le temps écoulé. A ce second engrenage à vis sans fin est fixé le ressort de lancement directionnel. Si le moteur tourne dans la bonne direction, le ressort entre en contact avec le logement du compteur et glisse sur le second engrenage à vis sans fin. Si le moteur tourne dans la fausse direction, le ressort entre en contact avec la face axiale de l'aimant, arrêtant la rotation de l'aimant et l'entraînant à tourner dans la bonne direction.

Abstract: A magnified phased array antenna system (10) incorporating a digital beamforming network (22) therein. The magnified phased array antenna system (10) comprises a reflector system (12) employing a transfer lens (14) disposed at the focal plane of the reflector system (12) and an antenna array (20) which illuminates or receives energy from the transfer lens (14). In satellite to/from ground links where the field of view is limited, the present invention achieves adequate gain using a minimum number of antenna elements. The digital beamforming network (22) provides multibeam capability in an effective manner. The digital beamforming network (22) provides for fast scanning spot beams and reconfigurable area coverage beams. The present invention has a reduced number of elements, and its reliability is improved because of redundancy in the array. The use of digital beamforming provides for multiple, simultaneous, reconfigurable beams.

Abstract: When making a hole in a component (3) by means of a hollow-cylindrical drilling tool (4), first of all a stop, designed as a disc (1), is fastened to the surface of the component (3) and then, after slipping the drilling tool (4) over this stop, the hole is made. During initial drilling, the stop consequently prevents the drilling tool (4) becoming misaligned by the said stop bearing against the inner contour of the drilling tool (4). The fastening of the stop on the surface of the component (3) can be performed in a known way, for example by adhesion or by means of elements (2) driven directly into the component. Drilling tools of smaller diameter can be guided by the outer contour, for example the head of the driven-in element (2), or by the inner contour of a template.
