Patent EP-0792701-A1 (EP)
Inventor: IZAWA MASARU - KANOKODAI-MINAM
IPC: B21B1/08
Filed: 1996-08-12
Abstract: The present invention relates to a hot rolling method of steel products and a hot rolling roll for steel products, both of which are effective in preventing steel products, particularly stainless steel products, from seizing between the rolls and the steel products to be rolled, preventing wear of the rolls, and preventing the deterioration of both the rolls and the steel products, when the steel products are subjected to hot rolling. 
     The method for the hot rolling of steel products according to the present invention, comprises rolling steel products while forming a film of an oxalate (such as iron oxalate, calcium oxalate and the like) on the roll surfaces which have contact with the steel products to be rolled. In particular, the rolling is effected while cooling by using, for example, as a part or all of the roll cooling water, an aqueous oxalic acid solution or an aqueous solution containing a water-soluble oxalate, and an aqueous solution containing water-soluble calcium compound, and jetting these solutions against the rolls, during the course of hot rolling from nozzles in separate lines. 
     In addition, the method for the hot rolling of steel products according to the present invention may be carried out by immersing rolls for hot rolling of steel products in an aqueous oxalic acid solution, or coating or spraying an aqueous oxalic acid solution on the roll surfaces which have contact with the steel products to be rolled, thereby, forming an iron oxalate film, and rolling the products with the iron oxalate-bearing rolls. 
     The hot rolling rolls for steel products, according to the present invention, have an oxalate film on the roll surfaces which have contact with the steel products to be rolled.

Abstract: L'invention concerne un transistor à effet de champ dont la sensibilité à un champ magnétique peut être commutée (SMAGFET). Un mode de réalisation préféré de ce transistor comprend une structure MAGFET dont le drain présente deux contacts (3, 4) de dimensions égales, une zone de grille composée de deux régions G1 et G2 (5, 6) isolées électriquement, de dimensions égales et séparées par une troisième région Gc (7) de grille, laquelle est isolée, située le long de la ligne de symétrie du dispositif et chevauche légèrement G1 et G2. Ce transistor comprend une source (1) commune. En modifiant la tension de grille appliquée sur Gc (par rapport au contact de la source commune), on peut commander la sensibilité magnétique dudit transistor. En appliquant une première tension sur Gc, on bloque l'échange des porteurs à partir des canaux situées sous G1 et G2. Dans le cas d'un champ magnétique appliqué, ce blocage empêche les porteurs déviés par la force de Lorentz de traverser la ligne de symétrie et de redistribuer les courants du drain, c'est-à-dire que la sensibilité au champ magnétique est virtuellement nulle tandis que les courants du drain ne sont pas affetés par l'induction magnétique. En changeant la tension appliquée sur Gc pour la porter à un second niveau, l'échange de porteurs à partir des canaux situés sous G1 et G2 peut avoir lieu, ce qui, dans le cas d'un champ magnétique appliqué, permet aux porteurs déviés par la force de Lorentz de traverser la ligne de symétrie et de redistribuer les courants du drain.

Abstract: A stent (11) or other endoprosthesis is provided from
a single strand of biocompatible and resilient material
into which spring coils (13) are formed by winding the strand
through in excess of 360°. The thus-formed coil springs
are positioned along outside edges of the endoprosthesis,
with legs (12) joining the coil springs in order to form a
generally zig-zag structure. When the endoprosthesis is
compressed for endoluminal delivery, the coil springs
allow for large angular deflection between adjoining legs
while avoiding plastic deformation of the coil or of the
legs.
The legs can be of the same length (12) to form a right cylindrical
stent configuration; or have differing lengths (22,23) in a helical
winding arrangement, resulting in the stent taking on a generally
helical configuration in forming an overall cylindrical device.
