Inventor: VISSER EELCO GERBEN
IPC: G11B5/127
Filed: 1983-01-26
Abstract: The head (1) has a (monocrystalline) core (2) of a magnetizable material which provides a substantially closed path for magnetic flux (B in write/read operations. In order to provide a magnetic heaa which has an improved signal-to-noise ratio in particular in the frequency range from 0.5 - 10 MHz, the magnetizable material of the core (2) shows essentially an uniaxial magnetic anisotropy having an easy axis of magnetization which is transverse to the plane of the path for the magnetic flux. Said orientation of the easy axis of magnetization is produced in one embodiment by coating the faces of the core which are parallel to the path for the magnetic flux with layers of non-magnetizable material (8,9) which exert a (tensile or compressive) stress in said planes.

Abstract: La présente invention, appartenant à la catégorie des bobineuses automatiques de fil métallique, a trait à une application plus simple du principe connu selon lequel un fil tendu choisi la distance la plus courte entre deux points, mais si cela n'est pas le cas, il n'aura de préférence pour aucune position particulière, sauf pour suivre l'enroulement sur le tambour. Cela peut être effectué par une poulie mobile se déplaçant le long d'une piste en forme d'arc dans un plan perpendiculaire entre le tambour et la poulie fixe. Le rayon de cet arc dépend de la distance relative entre la poulie de bobineuse et le tambour et la poulie fixe, de la largeur du tambour et de la hauteur du sommet de la piste au-dessus de la ligne de base, formée par la tangente sur le tambour et la poulie fixe. La poulie peut être montée sur un bras oscillant, mais, en vue d'une réduction de dimension et d'une meilleure adaptation aux phénomènes théoriques et pratiques, le cadre de la poulie devrait pivoter et rouler simultanément. La bobineuse doit être contrebalancée de façon à conserver sa position primitive lorsque le fil se relâche. Une telle construction permet un bobinage très compact pour un treuil.

Abstract: There is provided, for the improvement of single part inventory and shipment as well as easing the handling in the production and/or assembly of a frame for band conveying devices, the frame formed from longitudinal beams held together by cross beams. The longitudinal beams of which in each case are formed as sections open towards the conveying device with outer web and top web extending away from its upper end, with as few single parts as possible and without cost-intensive connection elements and which have adequate load-bearing capacity yet provide significant weight reduction simply, quickly and conveniently in the manufacturing plant for delivery ready assembled or at the site of use despite universality to a very large extent with regard to the most widely differing conveying width and length and different load-bearing capacity properties from sections of the simplest possible, and accordingly most inexpensive cross-sectional contouring. The longitudinal beam sections possess according to the invention in each case at the free end of their top web a connection flange extending away downwards and both longitudinal beam sections are connected with one another by a distance piece formed as a U or a C section. The two side or edge webs of the distance piece away from its central web approximately complementarily to the adjoining longitudinal beam section connection flange are in each case connected with this.

Abstract: Die Erfindung betrifft ein Verfahren zur Reparatur von Transmissionsmasken, bei dem nach einer Inspektion der Maske und der Speicherung der Daten (Ortskoordinaten) von Maskenfehlern die zu reparierende Maske auf ihrer Vorderseite ganzflächig mit einem Photoresist beschichtet wird. Es werden bestimmte Bereiche der Photoresistschicht über der zu reparierenden Maske mit nichtoptischer oder optischer Strahlung belichtet, um den Photoresist zu vernetzen, wobei die zur Vernetzung erforderliche Dosis von dem jeweils verwendeten Resist abhängt. Im Falle eines positiven Resists wird anschließend eine ganzflächige Belichtung durchgeführt. Die nicht oder nur einmal belichteten Bereiche der Photoresistschicht werden konventionell entwickelt und dabei entfernt. Dann wird die Maske bei der Korrektur von Maskenlöchern von der Rückseite her mit Gold bedampft, wobei die vernetzten Bereiche der Photoresistschicht als Unterlage dienen. Diese werden nach der Bedampfung mit Gold durch ein Plasmaätzverfahren entfernt. Da von dem Belichtungssystem aufgrund eines Vergleichs der Ortskoordinaten von Maskenfehlern mit den gespeicherten Strukturdaten der Maske nur die Bereiche der Photoresistschicht über Maskenfehlern belichtet und vernetzt werden, läßt sich die Maskenkorrektur im Millisekundenbereich durchführen.
