James Edward DeBard has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4068368
    Abstract: A silicon controlled rectifier has a triangular base with a planar mounting surface and holes at the apices of the angles to receive screws for mounting the rectifier to a heat sink surface. An anode ring having a skirt is threaded to a flange on the base and a semiconductor pellet is positioned on the base within the flange. A spring loaded cathode tube is positioned coaxially within the anode ring in engagement with the semiconductor pellet and a spring loaded gate is positioned coaxially within the cathode tube in engagement with the pellet to pressure mount the pellet on the base. A predetermined torque is applied to the anode ring when assembling it to the base to provide an accurate, predictable load on the pellet.

  • Patent number: 4063348
    Abstract: A silicon controlled rectifier having a triangular base with a planar mounting surface and holes at the apices of the angles to receive screws for mounting the rectifier to a heat sink surface. A cylindrical anode is connected to the base and a semiconductor pellet is positioned on the base within the cylindrical anode. A spring loaded cathode tube is positioned coaxially within the cylindrical anode in engagement with the semiconductor pellet and a spring loaded gate is positioned coaxially within the cathode tube in engagement with the pellet to pressure mount the pellet on the base.
