Abstract: A tamping shoe for a vibration rammer has a plurality of through holes communicating between an under surface and an upper surface. The through holes permit the escape of air trapped between the under surface and a surface being tamped, and thereby reduce the amount and pressure of air compressed under the tamping shoe. This reduces noise pollution produced during tamping. In a preferred embodiment, the through holes are tapered outward in the direction of air flow. Air passing through a through hole in a mount is released through a further through hole bored through a wall of the mount.

Abstract: A solidified amorphous alloy material is produced from a melt of its desired metal material. A melt feeding route is provided with a first-stage quenching zone. The melt is quenched to a predetermined temperature in the first-stage quenching zone. The thus-quenched melt is then introduced into a second-stage quenching and solidification zone, whereby the melt is cooled further and solidified into a solidified material having an amorphous phase.
