An anvil system for use in an ultrasonic bonder includes an anvil assembly including an anvil bar having an anvil aperture in at least one anvil bar longitudinal end, the anvil aperture having an anvil aperture inner surface, a shaft separate from the anvil bar and partially disposed in the anvil aperture, the shaft having a circumferential surface and extending outwardly beyond the anvil bar longitudinal end, and a first elastomeric shaft O-ring disposed on the shaft between the shaft circumferential surface and the anvil aperture inner surface; a mounting bracket with a mounting bracket hole having a hole surface; a bushing disposed in the mounting bracket hole and sized to accommodate an end of the shaft, the bushing having a bushing inner surface; and a second elastomeric shaft O-ring disposed on the shaft between the shaft circumferential surface and the bushing inner surface.

It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.

Systems and methods to improve weld quality are described. For example, certain systems and methods described use weld quality monitoring as feedback to an ultrasonic welding process to improve weld quality. Still other systems and methods provide improvement to double sided and single sided ultrasonic welding through the use of selected multiple pulses.

Disclosed is a method of joining different materials including a polymer composite and high-tensile steel, at excellent joining strength and, more particularly, a method in which various variables in friction bit joining are designed and adjusted to improve joining load between different materials.

This vibration welding device is a device that vibration welds an airbag holding box and an installment panel having a tear line. The vibration welding device is provided with a support jig that carries and affixes the installment panel during vibration welding. The support jig is provided with a groove that permits thermal expansion during vibration welding of the installment panel at a position differing from the tear line.

An ultrasonic welding system includes a movable ultrasonic welding stack for applying vibrational energy to a workpiece. A motion control system controls the motion of the ultrasonic welding stack and one or more sensors sense a control variable and output a corresponding control signal. A controller provides control inputs, based on the control signal, to the motion control system and causes, following initiation of a welding operation, an automatic change of speed of motion of the ultrasonic welding stack. The automatic change of the speed is a function of at least one control variable until the control variable reaches a predetermined value.

The present invention concerns A sonotrode with a wheel-shaped portion having a wheel axis and of a diameter d, which has two substantially circular main surfaces and a substantially cylindrical sealing surface of the width b, that connects the main surfaces. To provide a corresponding sonotrode in which the triangular frequency differs markedly from the main frequency it is proposed according to the invention that at least one main surface has a non-central thickened portion which in a sectional view perpendicularly to the main surface has a convex region which is not arranged on the wheel axis.

A method for producing a connector, in particular for repair, in particular in the field of aviation and aerospace, including the steps of: providing a base layer; attaching a first layer of fiber composite material having a first rigidity to the base layer; attaching a second layer of fiber composite material having a second rigidity to the first layer, offset therefrom, the second rigidity being greater than the first rigidity; and riveting the first layer to the base layer and riveting the second layer to the first layer and to the base layer.
