APPARATUS FOR TREATING A METAL STRIP
An apparatus for treating a metal strip after it has exited from a coating container with a liquid coating material, for example zinc is provided. The apparatus includes a blow-off device arranged above the coating container having an air outlet gap for blowing off excess parts of the still liquid coating material from the surface of the metal strip after the passing of the metal strip through the coating container. An electromagnetic stabilizer is arranged above the blow-off device and has a plurality of individual magnets for stabilizing the metal strip after leaving the coating container and the blow-off device. In order to further increase the efficiency of the apparatus, at least some of the magnets of the stabilizer are formed as pot magnets with pot coils.

A micro fabricated electromagnetic device and method for fabricating its component structures, the device having a layered magnetic core of a potentially unlimited number of alternating insulating and magnetic layers depending upon application, physical property and performance characteristic requirements for the device. Methods for fabricating the high performing device permit cost effective, high production rates of the device and its component structures without any degradation in device performance resulting from component layering.
Electrically insulated electric conductor strip, in particular for electric motors and transformers
An electrically insulated electrical conductive strip (1), especially for electric motors and transformers, having an electrical conductor (2) in strip form that has an upper face (2a) and a lower face (2b), two lateral edge faces (2c) and one end edge face at each end, and having an electrical insulation (3) disposed on at least one face of the strip (2a, 2b). The insulation (3) has an enamel layer (3a) and an adhesive strip (3b) bonded to the lower face (2b) and/or the upper face (2a) of the electrical conductor (2) in strip form, in each case at least in a region (4) that directly adjoins a lateral edge face (2c).
EQUIPMENT FOR MANUFACTURING GRAIN-ORIENTED ELECTROMAGNETIC STEEL SHEET
In the present invention, film forming performed under reduced pressure conditions on the surface of a grain-oriented electromagnetic steel sheet which is passed through the inside of a film forming chamber after finish-annealing. A plurality of stages of inlet-side reduced pressure chambers arranged on the inlet side of the film forming chamber have an internal pressure which becomes closer to the internal pressure of the film forming chamber as the inlet side reduced pressure chambers approach the film forming chamber. A plurality of stages of outlet-side reduced pressure chambers arranged on the outlet side of the film forming chamber save an internal pressure which becomes closer to atmospheric pressure as the outlet-side reduced pressure chambers are distanced from the film forming chamber. The inlet-side reduced pressure chambers and the outlet-side reduced pressure chambers comprise: partition plates which define each reduced pressure chamber and in which are formed a sheet-passing hole having a shape through which the grain-oriented electromagnetic steel sheet can pass; and sealing pads arranged on the upper and lower sides of the sheet-passing hole in the partition plates. Due to this configuration, harm to the grain-oriented electromagnetic steel sheet after finish-annealing is suppressed.
MAGNETIC CORE WITH VERTICAL LAMINATIONS HAVING HIGH ASPECT RATIO
A method for manufacturing a vertically-laminated ferromagnetic core includes (a) depositing a conductive seed layer on or over a first side of a substrate; (b) depositing a masking layer on or over a second side of the substrate, the first and second sides on opposite sides of the substrate; (c) forming a pattern in the masking layer; (d) dry etching the substrate, based on the pattern in the masking layer, from the second side to the first side to expose portions of the conductive seed layer; and (e) depositing a ferromagnetic material onto the exposed portions of the conductive seed layer to form vertically-oriented ferromagnetic layers.
