A medical information access and processing system includes a plurality of different wireless tag reader devices and a plurality of interfaces for receiving tag information, derived from reading a plurality of corresponding identification tags, from the tag reader devices. The pre-expanded particles are obtained by having as a base resin, a polypropylene resin composition comprising polypropylene resin, a compound having a triazine skeleton and molecular weight of at most 300 per triazine skeleton unit and as a random component, hydrophilic polymer and inorganic filler and water as the foaming agent. The metal filament manufacturing apparatus includes an induction coil upwardly bent in the form of a nose shape at regions thereof where metal filaments are discharged while being soared up, respectively, so as to prevent the molten metal of each of the metal bars from being affected by the induction coil during soaring of the metal filaments. A circuit provides a condensing condition output as a function of the sensor outputs.
