  • Publication number: 20040180583
    Abstract: The constitution of a further miniaturization of a mold pin is provided which improves concentrative mounting of the mold pin and simplifies a fixing cable to the press-fitting pin. A mold pin for cable terminal forms soldered portions for fixing conductive lines protruding from the connecting end of cable at the base end of each of the press-fitting pins where the soldered portions form notch portions and at proper positions of its edge portion and solder in such a manner that the conductive lines of the cable connecting ends are inserted into the notch portions and the notch portions fills with the conductive line to an appropriate thickness, and buries the soldered portion inside the resin mold body.

  • Patent number: 5799936
    Abstract: A sheet stacking apparatus having a frame with an inlet for sheet stock and first and second sheet receiving structures. A sheet guide member is provided and is movable between positions for facilitating guiding of the sheet stock to a respective one of the first and second sheet receiving structures. A sheet stock size selection device produces control signals indicative of a size of the sheet stock inputted at the inlet. A control device is responsive to the control signals for controlling movement of the sheet guide member. The sheet guide member includes a clamp member thereon movable into and out of engagement with a support in one of the sheet receiving regions to physically hold the sheet stock delivered thereto in place. The sheet guide member additionally includes an auxiliary roller and a lever arm with a linkage interconnecting the lever arm, the sheet guide member and the sheet clamp member.
