When a polyethylene bag with medical wastes received therein is supplied to a cylindrical-shaped housing and a compression device is used to lower a piston to compress the medical wastes, the piston is repeatedly caused to go up and down to accomplish stepwise compression whereby the polyethylene bag with medical wastes received therein is prevented from entering into a clearance between an inner wall of the cylindrical-shaped housing and the piston and from bursting due to rapid compression, and when cake obtained by melt sterilization and volume reduction with heating compression is discharged, a gate is fully opened to lower a lower surface of a heating device of the piston to a point distant several millimeters from an upper surface of a heating device of the gate to enable forcedly scraping off the cake adhering to the heating device tightly joined to the piston upon closing of the gate.

A pair of tubular products of polyarylene sulfide having end faces to be welded are welded to each other by heating the end faces by a hot plate in no contact with the end faces to a surface temperature which is at least the melting heat-absorption peak temperature and at most 80.degree. C. above the melting initiation temperature of the polyarylene sulfide, and abutting the end faces under a pressure of 50-1500 kPa when the end faces are at a surface temperature which is at least 10.degree. C. above the melting initiation temperature and not exceeding the melting heat-absorption peak temperature of the polyarylene sulfide. As a result, a welded tubular structure having a weld with a small inside bead but having a sufficiently large weld strength can be obtained with substantially no thermal degradation and at a good operating efficiency.

An electrode substrate for a fuel cell having a high porosity, a good mechanical strength and electroconductivity and a sharp distribution of pore radii is prepared by a process comprising mixing 30 to 50% by weight of carbon fiber, 20 to 50% by weight of a binder and 20 to 50% by weight of an organic granule, press-shaping the resultant mixture, curing the shaped product and calcinating the cured product.
