Predetermined amounts of materials containing elements of Bi, Pb, Sr, Ca and Cu are weighed, mixed and subjected to steps of calcining, milling, and drying, and thereafter an organic binder and an organic vehicle are added thereto to prepare a (Bi, Pb)2+aSr2Ca2Cu3Oz superconductive paste, which is applied to the surface of a substrate or a board in a thickness of 260 μm or more and dried. Thereafter, the paste is first subjected to burning at temperatures of 835° C. to 840° C. for 100 hours, then pressurization, and further burning at temperatures of 835° C. to 840° C. for 100 hours, thereby preparing an oxide superconductor thick film having a film thickness of 130 μm or more having a high Jc and Ic.

摘要： A method of detecting whether the ram of a punch press machine follows the upper die assembly of the machine after the pressing of a work piece involving the monitoring of current flow through an electrical circuit. The electrical circuit consists of an electrical conductor, located on the side of the ram, held in the electrically conductive state. The electrical conductor and an earthing path function as a watching switch for watching the position of the ram controlled by a controlling device to determine whether the upper die assembly follows the ram or not by electrically detecting whether the ram comes in contact with the upper die assembly. A first allowable detection time and a second allowable detection time are preliminarily set in order to electrically detect that the ram comes in contact with the upper die assembly within particular thresholds. If contact of the ram with the upper die assembly is detected within the second allowable detection time in excess of the first detection time a preliminary announcement from the controlling device is issued to indicate that the upper die assembly followed the ram with a delay. If the foregoing contact is detected in excess of the second allowable detection time, a determination that the upper die assembly does not follow the ram is made and an alarm is issued from the controlling device to stop operation of the punch press machine.
