A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.

An electric heating pad for warming a patient. The electric heating pad may be a heated underbody support, heated mattress or heated mattress overlay. An embodiment of the heating pad includes a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges. The heating pad may also include a shell covering the heating element and comprising at least two sheets of flexible material (e.g., two sheets may be one sheet folded over to form at least two sheets). The two sheets of flexible material may be coupled together about the edges of the heating element by a weld. The material of the two sheets may include urethane. In some embodiments, a catalyst to accelerate hydrogen peroxide decomposition is coated on or impregnated into an element within the shell, or on the interior surface of the shell.

An ultrasound horn is provided which vibrates a bonding tool, attached at a tip, in a plurality of directions with a simple structure. There is provided an ultrasound horn having: a longitudinal vibration generator; a horn portion; and a torsional vibration generator. The torsional vibration generator includes a body including a polygonal pillar portion, second layered elements in which a plurality of second piezoelectric elements are layered, and which are attached to side surfaces of the polygonal pillar portion, weights, and a pressure application ring which applies a pressure by pressing the second piezoelectric elements against the polygonal pillar portion via the weights.

A manual universal punching and welding apparatus includes a body frame having at least a vertical wall; a pair of supporting arms that are attached to the body frame and clamp a portion of the work object; a punching head that rotates clockwise and counterclockwise in a plane defined by the vertical wall of the body frame; and a welding part for welding the work object loaded on the work object loading part of the punching head. As for an efficiency of the present invention, a single manual punching/welding apparatus may produce all types of parts that require punching and welding. In addition, compared to the maintenance of a large number of designated machines, only one universal machine would desire maintenance, which greatly reduces the burden of overall maintenance.

An ultrasonic bonding device includes a stage and an ultrasonic horn. A first flat member and a second flat member to be bonded are placed on the stage. The ultrasonic horn includes a press part to be pressed on a laminated portion of the first flat member and the second flat member. The stage includes a lower-side surface, a higher-side surface, and a step wall surface. The first flat member is to be placed on the lower-side surface. The higher-side surface is positioned higher than the lower-side surface by a predetermined step height. The second flat member is to be placed on the higher-side surface. The step wall surface is positioned in a boundary between the lower-side surface and the higher-side surface.

An ultrasonic welding apparatus joins metal pieces, such as wires, which are placed in a weldment zone where the metal pieces are subjected to pressure through a compressive height anvil and an adjustable width anvil, and intimate contact is made with a sonotrode of an ultrasonic stack. A first electric motor actuates movement of the height anvil to develop a compressive force for ultrasonic welding of the metal pieces. A second electric motor can position the width anvil before and during welding. A sensor, such as a load cell, measures the compressive force developed. The sensor directly can measure the load on the height anvil independent of the ultrasonic stack. A software algorithm can compensate for deflection of the load cell sensor and lost motion in the first electric motor actuating movement.
