    摘要: A switch for as an electromagnetic contactor, a circuit breaker for wiring, an air circuit breaker and so on is provided. The switch comprises a fixed contact 8A joined to a fixed contactor 8, an movable contact 6A joined to a movable contactor 6 to face the fixed contact, a plurality of arc extinguishing metallic plates 13 arranged with predetermined distances and in parallel to the fixed contactor 8 at the side of the end portion of the movable contactor 6 and a commutation plate 15 placed at the opposite side of the fixed contactor so as to interpose the movable contactor. In the switch, an end of the arc extinguishing metallic plates 13 is extended toward the movable contactor 6, and the end of the extended portion is cut to form leg portions 13fa, 13ga which allows the movement of the movable contact 6A, and it is moved to contact with the fixed contact 8A, whereby an arc produced between the movable contact 6A and the fixed contact 8A is rapidly attracted to the arc extinguishing metallic plates to allow interruption of a large electric current.

    摘要: Coated sheet molding compound (SMC) parts are produced by transferring mold devices between a main press and at least one auxiliary press and by completing the compressing and curing of the coated SMC parts during the transfer of the molds. In the main press the SMC sheet is compressed and cured to be formed into a desired shape, and the formed SMC part is coated in the mold, and in the auxiliary presses the other operation such as charging the SMC sheet, closing and opening the mold, removing the part, and the like are performed. Between the adjacent main press and auxiliary presses are means for transferring the molds between the respective presses. Levelling devices are provided associated with the molds for supporting the upper mold parallel to the lower mold, and during the transfer the coated SMC part is further compressed and cured in the mold by suitably controlling the levelling devices. This method can be sufficiently applied to mass production systems such as automobiles or the like.
