The piston 62 is advanced and the cooling water is spouted from the tip opening hole 30c through the gap passage 30 to cool each part of the metallic mold 1. The temp. of the metallic mold 1 is detected with a temp. sensor 50, and at the time of becoming the suitable temp., the feeding of the cooling water is stopped.  The forming cycle time can be shortened and the trouble of galling, burning, etc., can be eliminated.

Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To provide an organic electrolyte secondary battery in which deterioration in discharge capacity accompanying charge/discharge cycles is retarded and cycle life is lengthened by using LiMn2 O4 synthesized from lithium iodide and manganese dioxide as a positive active material. SOLUTION: LiMn2 O4 , prepared by heating lithium diode (LiI) and manganese dioxide (MnO2 ) in a nitrogen atmosphere at about 300 deg.C, is used as a positive active material of an organic electrolyte secondary battery. Metallic lithium or an lithium alloy (such as LiAl and LiPb) is used as a negative active material, and a solution prepared by dissolving LiClO4 in 1,2-dimethoxy ethane, for example, is used as an electrolyte. Lithium ions of the negative material, moved to a positive electrode by discharge reaction, are effectively deintercalated by charge reaction, and the charge/discharge cycle life in the organic electrolyte secondary battery is lengthened sharply.
