Abstract: An improved golf club wherein the surface of the face of the club is substantially flat, which is achieved by surfacing (milling) the club face, and wherein the edges of scoring lines (grooves) are made relatively sharp as a result of the surfacing operation. The sharp groove edges (and milling lines) of the present invention produce enhanced backspin and reduced sidespin when a golf ball is struck, which results in a relatively straight golf ball flight path, notwithstanding a glancing club impact angle. In addition, milling lines that may be formed on the club face are generally parallel to the scoring lines and hence enhance the club characteristics. The present invention also provides for methods of making a golf club that has the above features, including forging and casting methods. In either method, a club is processed to produce generally smooth and finished features with scoring lines formed in the face of the club.

Abstract: A tube expander having a tube expander body, a reciprocable member to be reciprocated with its surface facing a tube to be expanded which is mounted in a heat exchanger unit, and a mandrel mounted on the reciprocable member so as to be inserted into the tube for the expansion thereof. A support fixture, on which the heat exchanger unit is separably mounted, is movably mounted on a mounting table which is disposed towards the moving direction of the mandrel such that the support fixture is transported on the mounting table in the transverse direction relating to the moving direction of the reciprocable member. A holding mechanism is provided on at least one of the mounting table and a peripheral area thereof so as to hold the support fixture or the heat exchanger unit mounted thereon, introduce the heat exchanger unit with the tube to be expanded into a tube expanding area, and discharge the heat exchanger unit from the tube expanding area after expanding the tube thereof.

Abstract: Lead wires extending out from an electrical circuit device are removed from respective bonding pads to which they are bonded by a lateral shearing action. Shearing can be accomplished either unidirectionally, or with a bidirectional reciprocating movement. A shearing tool is provided with a single shearing projection for a unidirectional shearing, or with a pair of spaced shearing projections for bidirectional shearing. A vertical alignment is established between the tool and a first lead to be sheared, and this initial alignment is also used for shearing the other leads of the device. With the actual bond between a lead and its bonding pad occupying only a minor portion of the available surface area, a subsequent lead from a replacement device is bonded to the same bonding pad as the first lead by forming a new bond at a different site along the pad.

Abstract: A flat strip of metal is formed to provide a depressed center relief portion between two edge portions. Depressions are formed in the two edge portions and center slots are pierced across the center relief portion such that roller receiving slots are formed with slot end depressions at both ends of the roller receiving slots. The partially formed bearing cage is then formed into a circular hoop such that the edge portions form rings at the axial ends of the circular hoop. The resulting roller bearing cage of the present invention may also be formed by other methods.
