Title: Wattage convertible superficial exothermic material
Inventor: MANABE HIROSHI
IPC: H05B1/02
Filed: 1978-05-31
Abstract: PURPOSE: Reduction of terminals of a superficial exothermic material and repression of leak current under a settled value at the converting time of outputs are capacitated by limiting a second resistance wire positioned on the charging side with use of a switch into the superficial exothermic material on one side.  
     CONSTITUTION: In concurrence of installing a first resistance wire 2 and a second resistance wire 3 on a supreficial exothermic material 1 with respectively connecting to terminals 4, 5, the other end of the both resistance wires is connected to a third terminal 6, the exothermic material 1 is connected through a change-over switch 8 to a power supply connecting plug 7. By this modality, when switches 8, 8 are turned OFF, leak current can be dropped under a settled value, because the resistance wire 3 on one side of the exothermic material 1 is charged at 100V of the potential, whereas the second resistance wire 3 of the superficial exothermic material 1 on the other side is mated with the grounding side to set it away from charging.

Abstract: PURPOSE: To improve the dimensional accuracy of the product, by correcting the dispacement of the dummy block's axis, caused by the swaging work for the billet, using the container.  
     CONSTITUTION: The position of the container 4, against the common center axis (l) of the stem 1, the mandrel 2, the dummy block 3, the billet 5 and the die 6 is a little displaced from the position for the extrusion work. The billet 5 is pressed against the die 6 and is swaged. A little gap is formed between the billet 5 and the container 4, and the bottom face of the billet 5 is upheld by the container 4, and under this condition, the billet 5 is compressed to swage, so that the billet 5 expands radially along the diameter against the center. As a result, the center of the billet 5 displaced and the dummy block 3 offsets from the common center axis (l). Then the offset of the container 4 is corrected to the position at the extrusion work by a suitable means. Hereby, the center axis (l) is aligned so that the accuracy of the thick walled part of the formed product is improved.

It is formed according to the following procedure during assembly of a fuel cell. After a fluorine resin film 4 is stuck to the end section of each rib electrode 2 having a matrix, the kneaded sealing material 6 is extruded upon the film 4 and then is rolled using a small roller. After that, a gas-separating plate 3 is placed over the material 6 and then a downward pressure is applied to the plate 3 to bring the rib electrode 2 and the plate 3 into close contact with each other. Due to the sealing material layer, the elasticity and the contact between the rib electrode 2 and the gas-separating plate 3 are improved and therefore no gas leaks from between the electrode 2 and the plate 3 even after repeated cycles of heating and cooling. Consequently, it is possible to produce a fuel cell with a remarkably long life.
