62	Method for forming protruded shaft of sealed case for memory device	US10958487	2004-10-05	US20050081361A1	2005-04-21	Hideyuki Miyahara
In a method for integrally forming a protruded shaft in the base of a sealed case for a memory device in which a storage medium is housed, a metal plate for manufacturing the base is placed on a die having a hole with an inside diameter that corresponds to an outside diameter of the protruded shaft, and a portion for forming the protruded shaft in the metal plate is positioned over the hole. The portion for forming the protruded shaft in the metal plate is pressed by a press tool from the side opposite the die, and the material of the portion for forming the protruded shaft is moved into the hole to form a hollow protrusion sealed off at a distal end. The sealed distal end in the protuberance is compression-molded from a direction opposite the press direction of the press tool by a compression tool disposed in the hole, and the protruded shaft is obtained. The protruded shaft with a large effective length that is free of cracks and ruptures can be integrally formed in the base.
63	Method of producing polygonal ring-shaped machine parts having complex cross-section	US10735740	2003-12-16	US20040123445A1	2004-07-01	Jun-Ichi Esaki; Tatsuo Ishikawa

The method comprises the steps of: forging a rod to prepare a notched blank 1 having large diameter parts 11 and the remaining small diameter parts 12; bending the large diameter parts 11 to form a first intermediate 3 of polygonal, open ring-shape and a complex cross-section with confronting ends; butting and welding the confronting ends of the first intermediate 3 to form a second intermediate 5; die-forging the second intermediate 5 to form a ring-shaped product 7; and subjecting the product 7 to necessary finishing step such as machining to obtain the final product.
64	Method of producing bushing	US10612160	2003-07-02	US20040020052A1	2004-02-05	Yusuke Haga; Toru Okabe; Nobuaki Haga
By press-fitting a cylindrical blank into a die with one of a pair of punches, and at the same time press-fitting small diameter end portions and tapered portions of the pair of punches into both ends of the cylindrical blank while restraining both end surfaces of the blank with cylindrical members movable on the outsides of the punches, the external circumferential surface of the blank is finish molded to the required diameter by the internal circumferential surface of the die and, at the same time, tapered surfaces are formed on the inner circumferential surface in both ends of the blank. The process produces a bushing with its internal surfaces accurately coaxial, and with the external surface accurately formed to the required diameter.

68	Method of producing socket plate for wobble plate compressors	US845213	1997-04-21	US5842580A	1998-12-01	Han Jung Lee; Han Hung Lee
In a method of producing a socket plate for wobble plate compressors an insert ring and a holed socket plate parent metal, having different mechanical and physical properties, are formed through extrusion processes prior to hot-forging the parent metal with the ring into a resulting socket plate. In the hot-forging step, the insert ring is seated onto the ring seat of a bottom mold prior to fitting the parent metal over the ring. Thereafter, a top mold is lowered onto the bottom mold, thus forming the resulting socket plate. A plurality of lubrication grooves are formed on the internal surface of the ring during the hot-forging step, with a plurality of projections being formed on the external surface of the ring. The projections bite into the inside wall of the holed parent metal thus integrating the ring with the parent metal into a single body.

71	Method and apparatus for simultaneously upsetting the ends of a cylindricl blank	US184857	1994-01-21	US5365765A	1994-11-22	Allen P. Gohl; Edmund W. Gohl
A punch press assembly (20) simultaneously upsets two ends (22) of a cylindrical blank (24) to produce a chain pin (34) having an extruded grain structure (134) which extends parallel to its longitudinal axis (B) into the upset regions of the chain pin (34). The punch press (20) clamps an upper die (30) to a lower die (26) via a mechanical crank (45), attached to the upper die (30) with lost motion (80,82). While maintaining the clamping relationship between the upper (30) and lower (26) dies, the downwardly directed force created by the mechanical crank (45) is transferred to the horizontal punches (36) by the two pairs of wedges (58,60). The two lower wedges (60) slide horizontally along two tie rods (84) and force the two punches (36) into the recess (28) to upset the ends of the cylindrical blank (24) to form a chain pin (34).

A process is disclosed for manufacturing flat bearing shells. A strip of material (2) is cut into bearing shell sections (26), these sections are bent into a semicircular shape, and the outer and inner sides (88, 58), as well as the parting surfaces (52) of the thus obtained bearing shells are calibrated. An oil groove (14) is shaped on the inner side (58) from parting surface (52) to parting surface (52). For the oil groove to be more easily shaped with a less complex milling tool, the oil groove (14) is continuously shaped, in particular milled, broached or sandblasted in the strip of material (2) before the strip of material is cut into bearing shell sections (26), and a cutting die (6) which matches the cross-section profile of the strip of material (2) after the oil groove (14) is milled is used to cut the strip of material into bearing shell sections (26).
