The present invention provides a magnetic glass fibre component comprising at least one glass fibre component coated and/or impregnated with an iron ore containing resin.

A bladder bag is a mold for molding inside of a composite material structure. The composite material structure includes a narrow portion formed by narrowing a part of the inside and a space portion formed so as to be adjacent to the narrow portion. The bladder bag includes a bladder bag main body and a cord-like member. The bladder bag main body includes a narrow molding portion for molding the narrow portion of the composite material structure, a space molding portion for molding the space portion of the composite material structure, and an air intake for introducing air. The cord-like member is provided inside the bladder bag main body, passes through the narrow molding portion from the air intake, and is connected to an inner surface of the space molding portion.

An electromagnetic coil with improved insulation properties at high temperatures. A bobbin is insulated by a thin ceramic composite layer that is produced by winding a glass or ceramic fiber over the support structure and impregnating it with a pre-ceramic polymer. The pre-ceramic polymer is then modified to form a ceramic SiO.sub.2 matrix around the fibrous layer. The ceramic matrix secures the glass or ceramic fibers in place and produces a dense layer. A ceramic coated magnet wire is then wound around the insulated support structure. The magnet wire is a conductor that is spiral-wrapped with a glass fiber impregnated with a pre-ceramic polymer.

A method for manufacturing a laminated iron core includes preheating a laminated body in which a plurality of iron core pieces are laminated and which includes a resin filling hole, measuring a temperature of the laminated body after preheating the laminated body, determining whether or not the temperature measured is within a predetermined range, feeding the laminated body into a molding device in a case where it is determined that the temperature is within the predetermined range, and filling the resin filling hole of the laminated body with a resin material in the molding device.

A diesel exhaust fluid (DEF) storage system may include a reservoir body having a magnet integrally formed about an inlet opening of the reservoir body. For example, the magnet may be molding about a perimeter of the inlet opening during a molding process in which the reservoir body is formed. In some examples, the inlet opening defines a lumen extending into an interior of the reservoir body with the magnet being positioned at a location along the lumen opposite an external end face. The position of the magnet may be effective to engage a corresponding magnet on a DEF fill nozzle, allowing DEF to be introduced into the reservoir body. By integrating the magnet into the reservoir body, protection features that prevent erroneous filling of the reservoir body cannot be removed or bypassed.

Disclosed herein are an elastic encoder and manufacturing method thereof. The elastic encoder of the present invention includes a reinforcing rim which has a reinforcing body and a reinforcing flange formed along a peripheral part of the reinforcing body and which is manufactured using a metallic material; and a plastic magnet which is bound to the reinforcing flange so as to surround the reinforcing flange, includes synthetic resin, rubber material, and magnetic powder, and has a plurality of magnetic poles magnetized in a circumferential direction.

To suppress positional deviations of magnetic members of a stacked core and prevent damage thereto when the stacked core is attached to a case. A method for producing a stacked core including a stack of foil-shaped magnetic members for fixation to a case with a fastening bolt includes preparing magnetic members each having formed therein a positioning opening, and a tubular collar adapted to be fastened to the case with the fastening bolt inserted therethrough, the tubular collar having a first receiving face for a head of the fastening bolt and a second receiving face for the case, stacking the magnetic members while arranging the collar within the opening, impregnating gaps between the stacked magnetic members as well as gaps between the openings of the magnetic members and the outer peripheral face of the collar with resin, and integrating the magnetic members with the collar by curing the resin.

The present disclosure describes techniques for fabricating a textile article that incorporates bristle-like filaments protruding away from a surface plane of the textile article. The techniques describe a fabrication surface, one or more magnets positioned on the fabrication surface, an intermediary layer that overlays the one or more magnets, and a wet laminate includes a resin substrate with magnetic particles. The presence of the magnetic particles may cause the resin substrate to form bristle-like filaments in areas that the resin substrate overlays the one or more magnets.

A system and method for authenticating a physical object. The method may include the steps of: (1) encoding a feed material with randomized information; (2) forming the object with the feed material such that one or more portions of the object have respective randomized signatures based upon at least some of the randomized information of the feed material; (3) reading the respective randomized signatures at the one or portions of the object; (4) creating a profile of the respective randomized signatures at the one or more portions of the object based upon information from the reading; (5) transporting the physical object to an authenticator, and transmitting the profile to the authenticator; (6) reading the respective randomized signatures at the one or more portions of the object by the authenticator; and (7) comparing the reading by the authenticator to the profile received by the authenticator to thereby authenticate the physical object.

To prevent the creation of unnecessary resin from the resin used for fixing the magnet, a device for manufacturing a magnet embedded core including a magnet embedded in resin filling a magnet insertion hole (104) extending axially in a motor core comprises a resin charging device (80) configured to charge the resin (114) in solid form into the magnet insertion hole (104), a magnet insertion device (90) configured to insert the magnet (110) into the magnet insertion hole (104), and a heating device (70) configured to heat the motor core (101) to melt the resin (114) in solid form received in the magnet insertion hole (104).
