Abstract: A sintering apparatus is provided. The sintering apparatus includes a case having an internal space formed therein and including a door provided in a front portion thereof to open and close the internal space, a magnetron coupled to the case and oscillating microwaves toward the internal space, a heat insulating unit disposed in the internal space to form a chamber space and blocking transmission of heat of the chamber space to the internal space, a susceptor unit disposed in the chamber space and having a sintering space in which a to-be-sintered material is accommodated, and a cooling unit cooling at least one of the case or the chamber space.

Abstract: Disclosed is a dental vacuum mixer which includes: a body comprising a magnet sensor, a mixing motor and a control means; a mixing unit coupler through which a driving shaft of the mixing motor passes to be combined; and a mixing unit composed of a mixing container, a cover combined with the mixing container, and a magnet installed at the position corresponding to the magnet sensor on the upper side of the cover.

Abstract: The present invention discloses an inductive heater for a dental technique and a method for operating the same. The inductive heater for a dental technique according to the present invention comprises: a bobbin with a chisel insertion hole connected to inner space at one end and a jointing unit protruded outwardly at the other end; an induction coil wound in the bobbin; an upper case comprising a mounting hole to which the bobbin is inserted and a bobbin fixing protrusion which is bolt-jointed to the jointing unit of the bobbin inserted inwardly through the mounting hole; and a lower case which is joined to the lower part of the upper case. The inductive heater for a dental technique significantly improves productivity of assembly due to a simple jointing structure of the bobbin. Also, the inductive heater is devised for worker's health and work environment by rapidly discharging wax vapor.
