    Abstract: Prior to manufacturing a product by additive manufacturing, a stress relief profile including frequency and amplitude parameters of an ultrasonic input is determined based on physical properties of the product, including resonant frequencies of the product and a material from which the product is manufactured. Successive layers of a material are added and energy is applied to incorporate the material of each layer into the product. A processor accesses stress relief profile parameters for each layer, determines whether a layer requires stress relief and determines a frequency and a power level for the stress relief at the layer. An ultrasonic input is applied with the determined parameters to relieve stress as the product is built up.

  • Patent number: 10741413
    Abstract: When a semiconductor element is bonded to a base plate electrode, a cushioning is used for protecting the surface of the semiconductor element. A protrusion having an outwardly cutting shape is formed around an area on the base plate electrode for bonding the semiconductor element to disperse and reduce shear force acting on the cushioning during the bonding, so that no cushioning adheres to the surface of the semiconductor element after bonding.

  • Patent number: 10404026
    Abstract: In a method for manufacturing a terminal-equipped electrical wire a core wire of an electrical wire is connected to a flat plate-shaped electrical wire connector portion of a terminal. An ultrasonic welding jig including an anvil and a welding horn is provided. After the electrical wire connector portion is placed on the anvil, the core wire of the electrical wire is placed on the electrical wire connector portion. By applying ultrasonic vibration along the axial direction of the core wire while pressing the core wire using the welding horn, the core wire is ultrasonically welded to the electrical wire connector portion. On the upper surface of the wire connection portions of the terminal, a positioning groove, into which the core wire is fit, is formed in advance, and the core wire is placed on the electrical wire connector portion while being fit into the positioning groove.

The ultrasonic blade is in acoustic communication with the acoustic waveguide such that the ultrasonic transducer is operable to drive the ultrasonic blade to vibrate ultrasonically via the acoustic waveguide. The clamp arm is configured to selectively translate between an inoperative position and an operative position. The clamp arm is positioned generally proximal to the ultrasonic blade when the clamp arm is in the inoperative position. The clamp arm is positioned lateral to the ultrasonic blade when the clamp arm is in the operative position. When in the operative position, the clamp arm is operable to move toward and away from the ultrasonic blade so as to capture and compress tissue between the clamp arm and the ultrasonic blade.
