Patent EP-0321514-A1 (EP)
Title: Method of coating copper conductors on polyimide.
Inventor: ZELLER FAITH MARIE
IPC: C23C18/34
Filed: 1988-05-23
Abstract: A module, for interconnecting integrated circuits, is comprised of a substrate, a layer of polyimide disposed thereon, and a plurality of spaced apart copper conductors on the layer of polyimide. This module is dipped into a solution of palladium chloride, thereafter it is dipped into a solution of sodium hydroxide, and thereafter it is dipped into an electroless plating solution for cobalt. As a result, a film of cobalt is deposited on all exposed surfaces of the copper conductors, but no cobalt is deposited on the exposed polyimide surface between the conductors. This cobalt film protects the copper conductors from corrosion, and it does not short the conductors together.

Abstract: Oligomères d'ester à terminaisons de vinyl éther à durcissement ou polymérisation particulièrement rapide, en particulier par polymérisation cationique provoquée par radiation en présence d'un sel onium. On forme les unités oligomères d'ester en faisant réagir un acide dicarboxylique avec un diol, mais les réactions d'esters et de triols ou de polyols polyhydriques supérieurs conviennent également, en particulier si l'on veut obtenir un produit très réticulé, pour produire des esters oligomères à terminaisons de carboxyl. Lesdits esters oligomères sont ensuite estérifiés avec des alcools à terminaison de vinyl éther qui peuvent être considérés comme des produits d'addition d'alkynes et de polyols, de diols en particulier.

Abstract: Procédé d'élimination des écailles d'oxyde qui se forment à la surface d'une feuille d'acier pendant la production d'une feuille d'acier au silicium directionnel, notamment pendant une étape suivant le recuit intermédiaire mais précédant le laminage à froid final. Ce procédé permet de former une rainure s'étendant dans le sens du laminage à la surface de la feuille d'acier pour aplatir la surface de ladite feuille après le laminage à froid final, ce qui permet d'effectuer avantageusement un laminage à froid final en tandem à haute vitesse et de produire avec un rendement élevé une feuille d'acier au silicium directionnel possédant d'excellentes caractéristiques magnétiques.

A guide (24), at least approximately parallel to the wheel brake cylinder (12), and a stop (26) are formed on the housing (22) of the intermediate support (20). A readjusting member (28) is axially displaceable to a limited extent in the guide (24). One of the brake shoes (16) is supported against one end of a stud (34), which can be displaced towards this brake shoe (16) by a force (C) acting on its second end when the brake is actuated hydraulically. The stud (34) is connected to the readjusting member (28) in a manner which is free from self-locking in relation to this force (C) but is self-locking in the opposite direction. When actuated hydraulically, the brake has a degressive characteristic whereas, when actuated mechanically, it has a progressive characteristic. <IMAGE>
