摘要:
A dip forming apparatus for continuously forming a cast rod includes a furnace for holding molten metal, and a crucible having an open top and a bottom wall. The crucible has a core wire-passing region vertically extending therethrough. The crucible has a hole formed through the bottom wall. A passage connects the furnaces to the core wire-passing region. A device is provided for keeping the molten metal in the furnace at a predetermined level so as to flow the molten metal from the furnace to the core wire-passing region through the passage. A partition wall is disposed in the passage and has a throttling orifice of a predetermined size formed therethrough so as to allow the molten metal to pass therethrough to limit the flow of the molten metal from the furnace to the core wire-passing region. A drive device moves the core wire upwardly at a preselected speed through the hole and the core wire-passing region, so that the molten metal in the core wire-passing region accretes on the core wire to form the cast rod.

An electrode wire for wire electric discharge machining a workpiece at high speed and high accuracy and a process for preparing the same are provided. The electrode wire comprises a core wire made of a copper clad steel wire, 10 to 70% of the sectional area of the copper clad steel wire being occupied by copper, and a copper-zinc alloy layer covering the core wire. The copper-zinc alloy layer is prepared by coating the core wire with zinc by electroplating or hot galvanizing, followed by heating to disperse copper in the zinc layer to convert the same into a copper-zinc alloy layer wherein the concentration of zinc is increased gradually along the radially outward direction. The preferable thickness of the copper-zinc alloy layer ranges from 0.1 to 15 microns and the average concentration of zinc in the copper-zinc alloy layer is preferably less than 50% by weight but not less than 10% by weight.

There is disclosed a bushing for use in an apparatus for continuously passing a core wire through a crucible holding molten metal to accrete the molten metal on the core wire to form a cast rod. The bushing is connected to the crucible for passing the core wire therethrough into the crucible. The bushing is tubular and has an engaging portion for engaging with the core wire passing therethrough. The engaging portion is made of ceramics material containing a major proportion of at least one selected from the group consisting of zirconia, silicon carbide and silicon nitride.

A golf club of the present invention comprises at least one adjusting mechanism. In the golf club, at least two specifications can be adjusted independently of each other. Preferably, a head, a shaft, a grip, or a joined part therebetween has an adjusting mechanism (1). The head, the shaft, the grip, or the joined part has further other adjusting mechanism (2). Preferably, the adjusting mechanism (1) and the adjusting mechanism (2) can work independently of each other. The number of the adjusting mechanisms is not restricted. Since the plurality of specifications can be adjusted independently of each other, a degree of freedom of adjustability is improved. These adjusting mechanisms can improve accuracy of the adjustability. The specification capable of being adjusted is not restricted.
