  • Patent number: 8231982
    Abstract: A composite of a metal and a resin, in which a shaped metal and a shaped thermoplastic resin are integrally joined by injection molding, and in which the perpendicular precision of the thermoplastic shaped body with respect to the shaped metal is improved, as well as a method for manufacturing the composite. A composite 40 of a metal and a resin is composed of a shaped metal 20 and a shaped thermoplastic resin that is integrally joined to this shaped metal 20 by injection molding. The shaped thermoplastic resin comprises a seat 42 and a boss 41 that protrudes from the seat 42. A runner 43 is provided which communicates with the seat 42 via two sprues and through which a molten thermoplastic resin that has been injected through an injection gate 45 flows into the boss 41 and the thermoplastic resin injected through the injection gate 45 flows through the sprues 47 to opposite locations of the boss 41 substantially uniformly, thereby filling the locations.

  • Patent number: 7311967
    Abstract: A thermal interface material is described for thermal coupling of an electronic component to a thermally conductive member. The thermal interface material includes a viscoelastic polymer matrix material, fusible solder particles in the matrix material, and filler particles in the matrix material. The solder particles have a melting temperature below a selected temperature (e.g. 157° C. for indium) and the filler particles have a melting temperature substantially above the selected temperature (e.g. 961° C. for silver). The filler particles keep the thermal interface material intact under adverse thermal and stress conditions.

  • Patent number: 5879815
    Abstract: A B-channel for use in a damper frame or sleeve is disclosed which is formed from a blank of sheet metal. The blank has a rectangular barrier wall, a pair of side walls formed along two opposing edges and end walls formed along opposing edges of the barrier wall. The side walls and end walls are folded perpendicularly to the barrier wall and tabs are formed on the end walls to be folded into the planes of the side walls. The B-channel is particularly useful in conjunction with a fire damper sleeve.

  • Patent number: 4271240
    Abstract: The invention relates to the cold extrusion of a part having a polygonal interior and a cylindrical exterior. Instead of the usual process of forcing a polygonal punch into a billet in a single extrusion step, the new method employs a plurality of extrusion steps, first forming a lobed preparatory blank and then in a second extrusion step providing a punch and die combination whereby the external lobes of the intermediate part are forced radially inwardly. In the second extrusion step a polygonal punch is used to provide the proper polygonal interior surface. A cooperating die is provided with an upper lobed cavity for receiving the lobed preparatory blank and this die is oriented with respect to the polygonal punch so that the interior lobes of the die are exactly opposite the flats of the polygonal punch.

  • Patent number: 4258458
    Abstract: A blank for a stone setting comprising a base and prongs extending radially therefrom, said blank having a planar lower side and a notched upper side, the notches at the upper side defining at the junctions of the prongs with the base hinges which enable bending the prongs upwardly relative to the base to form a stone cage and at the distal ends thereof a seat for the stone and tangs for fixing the stone against the seat. A method of making a setting including making the blank by striking it from malleable sheet metal, removing parts of the sheet metal from around the bank, stripping the blank from the sheet metal, using a punch to force it into a die for bending the prongs and tangs at their notched areas to shape it into a cage. A further method of setting a stone by seating a stone against the seat at the top of the cage and bending the tangs against the stone.
