Abstract: When a seat (3) (FIG. 6A) on which a wax layer (7) is formed via a melting reaction layer (5) is brought into contact with a head (2) and heated and pressed in this state, a melting reaction layer (6) forms below the wax layer (FIG. 6B).

When electrical current application and pressing are further continued from this state, the two melting reaction layers (5) and (6) diffuse each other. The result is that a ternary alloy bonding layer (10) containing Fe, Al, and Zn, which constitute the melting reaction layers (5) and (6) is formed between the seat (3) and the head (2) (FIG. 6D).

Abstract: The piston for a magneto-rheological fluid system is manufactured from a piston skirt of a material having a high magnetic permeability and a piston plate which closes one end of the piston skirt having a low magnetic permeability and therefore must be made out of a material such as stainless steel.

Abstract: On a setting cart which is movable back and forth between a setting station and a vehicle body assembly station, there are provided floor panel setting members, side sill receiving members and side panel forcing members which force side panels toward a floor panel from a lateral outward. In the setting station, the floor panel and the side panels which are set in position on the setting cart are transferred to a jig which is disposed in a side portion of the vehicle body assembly station. The side panels are welded to the floor panel by welding robots which are disposed at a level below the jig. In the above-described arrangement, the side sill receiving members and the side panel forcing members are set on the setting cart so as to be retractable into shunted positions free from interference with the welding robots in welding operation. The welding work by the welding robots can thus be started without waiting for the returning of the setting cart to the setting station.

Abstract: An arc-melting method is taught for the formation of metallic-second phase composite materials. The method involves the formation of an intermediate composite material comprising a relatively high loading of second phase particles dispersed in a metal matrix.

The final metallic matrix may be comprised of a metal, metal alloy, or intermetallic, while the second phase particles may comprise ceramic materials such as borides, carbides, nitrides, silicides, oxides or sulfides.

Abstract: A metal rod is supplied to a pair of bonding rolls provided with peripheral grooves forming a substantially circular roll pass that also receives at opposite sides of the rod a pair of metal strips of a different metal than that of the rod. The rolls press the strips against the rod and pull all three together through the roll pass, with the strips bent around the rod to enclose it. Before the strips reach the pass, an electric current passes through a length of each one to heat it to a solid-phase bonding temperature and to burn off contaminants. Also, before the rod reaches the rolls, it is heated to a solid-phase bonding temperature by means of an electric induction coil encircling it while it is passing through an enclosure maintained full of a gas providing a controlled atmosphere around the heated portion of the rod. The diameter of the roll pass is small enough to reduce the diameter of the product therein and simultaneously cause solid-phase bonding together of the heated strips and heated rod.

Abstract: Bonds are made between two work pieces by using foils exploded by electrical energy typically stored in a large capacitor. To increase the uniformity of the bond area, a foil having at least one slit cut in the direction of current flow is used. The foil strips separated by the slit are attracted together by the pinch effect when current is applied, tending to eliminate loss of foil through a jetting action during explosion. Platings are made by pressing the foil between the work piece and a plastic layer to which the foil does not adhere. In both bonding and plating, the capacitor is charged with energy sufficient to bring the foil just to its boiling point. This "tuning" is more efficient and minimizes heat and blast effects that might otherwise damage a small work piece.
