In a first aspect, a method is provided for manufacturing a permanent magnet module for a generator by using a mold with a resin inlet and a heating system for heating the inside of the mold. The method comprises placing inside the mold a module base with one or more receptacles for receiving permanent magnets, and inserting permanent magnets in the receptacles of the module base. The method further comprises closing the mold having in its inside the module base with inserted permanent magnets, and introducing resin into the closed mold through the inlet of the mold. The method still further comprises causing the heating system to operate for at least partially curing the resin. In a second aspect, permanent magnet modules are provided manufactured by performing any of the previous methods of manufacturing a permanent magnet module.
摘要:
An embedded material and an embedding apparatus and method. A compatible solute can be dissolved in a solvent. The object to be embedded can be coated with the solvent/plastic solution using, for example, addition and/or condensation polymerization. The solvent can be removed. The coated object can be inserted, snap fit, or submerged into a partially 3D printed substrate with or without the aid of ultrasonic embedding, thermal energy, joule heating, and/or the use of adhesives, and the 3D printing process resumes in order to fully embed the coated object within the 3D printed substrate. The coated object can be inserted, snap fit, or submerged into a partially 3D printed substrate with or without the addition of ultrasonic embedding, thermal energy, joule heating, and/or adhesives, and the 3D printing process resumes in order to fully embed the coated object within the 3D printed substrate.
摘要:
A wirelaying apparatus includes a tool arm with a tool head which carries a wirelaying tool. The tool has a cutting tip through which a wire is laid into a working surface of a workpiece. The workpiece is retained in a retainer and is moved relative to the wirelaying tool. In use, the cutting tip follows along an arcuate path while laying the wire into the working surface of the workpiece. Thus, more complex wirelaying configurations are achieved, such as a bi-helical wirelaying pattern in a generally cylindrical pipe fitting or a bi-spiral wirelaying pattern in a semi-cylindrical saddle coupler pipe fitting.
摘要:
A programmable shape device is described. The device comprises a wire grid made from a shape memory material. The grid is embedded in a transparent polymer. Under normal conditions, the device can be folded into any shape. Upon actuation, the device reverts back to a programmed parent shape. Such a device can be made into one shape during its desired use and another shape during storage or transportation. Methods of making and using a programmable shape device are described.
摘要:
An implant applicator and method for positioning a resistive implant material on a first plastic component to be used to form a resistive implant weld between that first plastic component and a second plastic component. The resistive implant material is heated and pressed into a targeted surface of the first plastic component to tack the resistive implant into place. The second plastic component is positioned over the tacked resistive implant and a weld formed in a known manner. The resistive implant material can be heated for tacking by passing an electric current through it before it is pressed into the first plastic component by a second member or by contacting the resistive implant material against a separately heated surface prior to pressing it into the first plastic component.

A wirelaying apparatus (2) includes a tool arm (21) with a tool head (22) which carries a wirelaying tool (30). The tool (30) has a cutting tip (31) through which a wire (12) is laid into a working surface (11) of a workpiece (10). The workpiece (10) is retained in a retainer (40) and is moved relative to the wirelaying tool (30). In use, the cutting tip (31) follows along an arcuate path while laying the (10) wire into the working surface (11) of the workpiece (10). Thus, more complex wirelaying configurations are achieved, such as a bi-helical wirelaying pattern in a generally cylindrical pipe fitting or a bi-spiral wirelaying pattern in a semi-cylindrical saddle coupler pipe fitting.
摘要:
A method of injection molding material around the surface of an object. The method involves positioning the object within the cavity of a first mold and holding the object through the use of a plurality of clamping mechanisms. Material is injection molded about the surface of the object such that the material encompasses the object's surface except for points of contact between the clamping mechanisms and the object. A plurality of protrusions, formed of injection molded material and extending outwardly from the surface of the object, are formed during the injection molding process. Thereafter the object is removed from the first mold cavity and positioned within the cavity of a second mold. The object is secured within the second mold cavity through engagement of the outwardly extending protrusions with the second mold. Additional material is then injection molded about the surface of the object with the additional material encompassing the object except for points of contact between the outwardly extending protrusions and the second mold.
摘要:
A wirelaying apparatus and method using a tool (30) having a cutter (31) operatively opening a cut in the interior bore surface (11) of a cylindrical pipe fitting (10), laying wire (12) into the cut and closing the cut using a flange closer (33). The wire (12) is delivered into the cut via an aperture (32) through the cutting means (31). Delivery of the wire (12) into the cut is thereby improved, overcoming the problem of wire running free within the fitting. In a second embodiment (see FIG. 12) the cutter (31) is rotatably mounted allowing a double helical coil to be formed without removing the cutter from the bore surface.

A laminated sheet having electromagnetic wave shielding effects and a manufacturing method therefor are provided wherein the laminated sheet is transparent, has electromagnetic wave shielding effects and is easily manufactured, moreover, an earthing terminal can be easily connected to the laminated sheet, and post-processing such as ultrasonic adhesion and the like can be easily conducted on the laminated sheet. In the manufacturing method, a conductive mesh-like sheet 13 and a thermoplastic resin sheet 12 are positioned between two molding plates 10 and 10 and heated, these sheets are integrally laminated by means of the application of pressure between molding plates. In addition, as the above-mentioned thermoplastic resin sheet 12, a thermoplastic resin sheet having at least one resin layer which has a thickness t1 which is two times or greater than the thickness t2 of the conductive mesh-like sheet 13 and which has uniform thermal properties is used. In the laminated sheet 1, at least one side 3a of the conductive mesh-like sheet 13 is imbedded and fixed within the resin layer 2. It is preferable for the laminated sheet 1 to have exposed portions 3null of conductive mesh 3 formed into a section in which exposed portions 3null of conductive mesh 3 are exposed above the resin layer 2, on one side.
