Abstract: A cable guide block has a guide groove for receiving and guiding an end portion of a cable having an elastically deformable sheath. The guide block is for use in a cable connection processing apparatus for making a cable connection by moving a cable pusher in a direction perpendicular to the guide groove and in a cable receiving direction in order to press the end portion of the cable onto a cable connection portion of a contact disposed below the guide groove. The guide groove has a pair of wall surfaces which are spaced apart by a distance which is greater than a diameter of the cable. At least one projection is formed on at least one of the wall surfaces so that the distance between the wall surfaces is less than the diameter of the cable. By the use of the cable guide block, the end portion of the cable is reliably sent along the cable receiving direction and inserted into the guide groove. The end portion of the cable is forced against the positioning projection in an elastically deformed condition.

Abstract: An aperture setting device for use in a drawing die, a chuck and so forth, in which at least three or more substantially triangular movable pieces are sequentially arranged in the form of a ring, an aperture is formed by one end portion of an inner side of each movable piece and the movable piece is movable along a side opposite its vertical angle on the side of the aperture, together with the other movable pieces. The movable pieces are disposed in a frame. By the movement of the movable pieces, the aperture can be varied in size without being changed in configuration.
