Abstract: A method for making micromagnets and magnets with a micro-polarization pattern on at least one surface thereof. The method includes the steps of molding a ceramic mold form including a cavity therein having a predetermined shape and a serpentine conduit path therethrough adjacent the cavity, the serpentine conduit path having a nominal diameter ranging down to as small as about 50 microns, sintering the mold form, supporting the mold form on a micro-porous substrate within a chamber, flooding one side of the mold form with a molten electrically conductive material, drawing a vacuum within the chamber on an opposite side of the mold form causing the molten electrically conductive material to flow into and through the serpentine conduit path toward the micro-porous substrate, cooling the molten electrically conductive material to form a serpentine electrical conductor in the mold form, forming a ferromagnetic element within the cavity, and imparting a micro-polarization pattern to the ferromagnetic element by transmitting an electrical current through the serpentine conductor.

Abstract: A elastically and reversibly deformable rubber mold for producing powder compacts is made of a material at least a part of which is a mixture of rubber and magnetic powder. In use, this rubber mold filled with the magnetic powder and subjected to a magnetic field and pressure with punches, thereby compressing the powder to form powder compact. This makes the distribution of magnetic field in the cavity of the rubber mold more homogeneous, and therefore, the distortion, cracking and chipping caused by inhomogeneity of the distribution of the magnetic field are reduced, so that the shape of the resultant powder compact is closer to the end product.

Abstract: A die for extrusion molding a resin bonding magnet. In the production of the magnet, a molten mixture of a magnetic powder and a resin are introduced into a cavity between an outer die and a mandril to which a magnetic field is applied. A steep temperature gradient along the die axis direction of the molten mixture and the cavity is achieved by making the outer die of a multiple layer structure along the die axis direction, utilizing two or more axially adjacent blocks or sheets made of the same or different materials whereby fluidity of the molten mixture is sufficiently high at the inlet of the cavity to enable the magnetic powder in the molten mixture to be sufficiently orientated in the direction of the magnetic field and then the molten mixture is cooled to a solidified state so that the orientation of the magnetic powder is not disturbed, thereby producing a magnetic having high magnetic properties.

Abstract: An appratus including a support structure which carries a positioning device having a valve positionable into contact with a damaged windshield. The valve includes a chamber for a repair liquid and passageways for the liquid and for the removal of air from the windshield damage area. A ball element of the valve is controlled by a hand held magnet and when unseated releases the liquid into a valve outlet defined by an O-ring seal. A hand pump with a lockable piston evacuates the valve and the damage site and subsequently opens to pressurize the site. A positionable mirror provides direct viewing and also a reflected image of the repair operation. A modified support structure permits repairs in curved and marginal areas of the windshield.

Abstract: A magnetic circuit component molding device for integrally molding a compound a center yoke with a ring-shaped magnet includes top and bottom press vertically arranged at opposed positions. A ring-shaped magnet is place on a bottom die between top and bottom press. The top and bottom press compress the compound against the ring-shaped magnet ring with a vertical pressure. A holder unit, separated in plural segments, having tapered outer circumferences is provided around the ring-shaped. A holder presser having a tapered inner circumference is mounted on the holder unit as tapered portions thereof are engaged together. A portion of the vertical pressure, when the top press compresses the compound, is transferred by springs 10 to the holder presser, and is amplified by the tapered portions and applied to the outer circumference surface of the ring-shaped magnet by the holder unit.

Abstract: Disclosed is a device for preventing the scattering of ejected molded articles in a plastic forming. The scattering prevention device includes screens made of a synthetic resin film and disposed at both sides of molds mounted on a fixed die plate and a movable die plate and inside a space defined by tie bars in such a manner that the molds can be screened, and magnetic assemblies coupled to each of two lateral ends of each of the screens for fixing the screen to the opposed molds or die plates, so that, while the molds are open, the screens are extended, while the molds are being clamped, the screens are contracted and folded. The height of each of the screens is set such as to be smaller than a gap between the upper and lower tie bars, so that the screens can be folded outwardly from between the upper and lower tie bars. Alternatively, the scattering prevention device includes bar-shaped coil springs, screens which can be folded in a bellows fashion, the screens being hung from the coil springs, magnetic assemblies for fixing both ends of each of the coil springs to the fixed and movable molds or the fixed and movable die plates, and hanging screens made to hang from the lower ends of the opposed fixed and movable molds.

Abstract: There is disclosed a magnetic printing base for one or more printing plates, a method of making the magnetic base, and a mold in which moldable,non-magnetic adhesive material is molded about various parts of the magnetic base. The base is structured to permit magnetic circuit devices and end plates to be interconnected by the non-magnetic material into a unitary arrangement. Each magnetic circuit device includes a flat magnet disposed between and in ccontact with a pair of flat magnetizable plates. The permanent magnetsextend short of the finaldesired dimension of the base. The plates and the molded material initially extend beyond the final desired dimension of the base, but are trimmed off by a cutter to the final desired dimension after assembly of the base. To obviate the tendency of the printing plate to creep or drift, the spacing between the magnetic circuits is such that the strength, at surface of the base, of the magnetic flux field between next adjacent pole plates of adjacent magnetic circuit devices is equal to the strength, at the surface of the base, of the magnetic flux field between the pole plates of a magnetic circuit device itself.
