  • Patent number: 9437881
    Abstract: There is provided a reinforcing material equipped with a cohesive/adhesive layer, having a proper initial adhesion force to an adherend, such as an electrolyte membrane, a catalyst layer and a gas diffusion layer, and which can be temporarily fixed readily. A reinforcing material produced by forming a cohesive/adhesive layer on a substrate. The cohesive/adhesive layer includes an aliphatic polyamide, an epoxy resin and a polythiol. When the reinforcing material is used, it becomes possible to correct the position of an adherend after the adhesion of the reinforcing material to the adherend. In addition, it can prevent the formation of wrinkles on the adherend or the like upon the adhesion of the reinforcing material. Therefore, a catalyst layer laminated membrane or the like which has a reinforcing material attached thereto can be produced readily without requiring the employment of any highly skilled technique.

  • Patent number: 6711999
    Abstract: A screen printing apparatus in which a squeegee head 13 is moved on a mask plate 12 thereby to print paste on a substrate through pattern holes 12a, slide contact portions 37A and 37B form respectively front and rear walls in the squeegeeing direction of a printing space 35 which reserves cream solder 5 therein and makes the cream solder contact with the surface of the mask plate 12 through an opening portion formed at the lower surface thereof. Each of the slide-contact portions is configured by a partition plate 39 for partitioning between the printing space 35 and the outside and a filling block 38 having a filling surface 38a which forms an acute angle with respect to the surface of the mask plate 12. In the squeegeeing operation, the filling surface 38a rolls the cream solder 5. Thus, the cream solder 5 can be filled into the pattern holes 12a without pressurizing the cream solder, and a problem caused by the leakage of the cream solder can be eliminated.
