Abstract: There are provided a pretreatment facility (1) and a incineration/melting facility (2). In the incineration/melting facility, an incineration chamber (3) and a melting chamber (5) are integrally formed through a partition wall (7) so that incineration residue can be continuously transferred. Fine crushed material finely crushed by the pretreatment facility (1) is supplied as fuel to a burner (4). This enables it to obtain melting heat source from waste, and to efficiently treat the waste at a low cost by directly superheating and melting non-cooled incineration residue from the incineration chamber (3).

Abstract: A precise feeding table apparatus which comprises an XY-table assembly including a Y-table and an X-table mounted thereon. Electric motors for supplying a driving force to feed the X- and Y-tables are set on a base of the table apparatus. A driving shaft of the electric motor for the Y-table takes the form of a ball screw to cause a guide carriage supported by the driving shaft to make a minute reciprocation. A moment derived from the reciprocation of the guide carraige is not directly transmitted to the Y-table. A connection rod moving jointly with the guide carriage is connected to an output shaft fitted to the Y-table by means of a coupling including a fluid bearing. The fluid bearing supports the connecting rod in contactless relationship, thereby preventing the vibrations and moments of the connecting rod from being transmitted to the output shaft.

Abstract: The apparatus comprises a drill power meter for producing an electric signal representing the drilling resistance of a workpiece, a filter for shaping the waveform of the electric signal, an integrator for integrating the output of the filter, a comparator for comparing the output from the integrator with a reference signal for producing a pulse when the former is larger than the latter, a first counter for counting the pulse, a second counter for counting the total number of measurements of the drilling resistance of the workpiece performed by the drill power meter, and means for comparing the counts of the first and second counters for judging the useful life of the drill.
