    摘要: A heating machine for heating an ingot of a metal such as a magnesium alloy. The heating machine has a heating chamber equipped with a RF induction coil capable of swinging about a horizontally axis. The coil is placed horizontally, and the metal ingot is fed into the coil from an introduction chamber by a pushrod. Stoppers prevent the ingot from falling from the RF induction coil when it is switched from its horizontal posture to its vertical posture. The coil is wound on a cylindrical member. A rotatable hollow shaft is firmly mounted to the holder in a perpendicular relation to a substantially axially central portion of the cylindrical member. A part of the coil is inserted in the hollow shaft via an insulating material. The rotatable hollow shaft is swung by a swinging mechanism. The induction heating coil is wound on a ceramic holder. A metal ingot is inserted in the holder with a given clearance. A plurality of pillars of L-shaped cross section are fitted over the holder to place it in position vertically and horizontally.

    摘要: An upper unit of an injecting molding apparatus includes an ingot entry for introducing into the apparatus an ingot to be molded and an ingot heating chamber for heating the ingot supplied via the entry, and a lower unit includes a crusher for crushing the heated ingot and an injecting machine having an axially movable screw shaft for slurring and injecting the crushed ingot into a mold. The upper and lower units are interconnected via a flexible connector unit which is flexible in a vertical direction to allow the lower unit to vertically displace relative to the upper unit. By disengaging the connector unit from the upper unit, the lower unit can be disconnected from and laterally pivoted with respect to the upper unit to permit easy access to both the units. This displacement of the lower unit permits facilitated maintenance operations of the apparatus. A lower door provided for openably closing an ingot exit hole of the heating chamber is a vertically pivotable door that does not require a large operating space.

    摘要: An absolute position detector samples and outputs a digital value of absolute position data of an object of detection at each predetermined sampling timing. An interpolation circuit interpolates between position data of different sampling timings provided by the absolute position detector, thereby to produce absolute position data at close intervals. Such arrangement produces absolute position data with a time resolution which is finer than the period of the sampling timing. A further circuit produces an incremental pulse train on the basis of the output of the interpolation circuit in correspondence to change in a value of interpolation for each interpolation step.
