A method includes disposing a hydride of a transition metal on a first metallic material, where at least one of the first metallic material or a second metallic material includes a surface oxide layer. The method includes performing a diffusion bonding operation to bond the first metallic material to the second metallic material. During the diffusion bonding operation, the hydride of the transition metal chemically reacts with the surface oxide layer.

A method for forming an electrical connection to a microscale electrically conductive fibre material electrode element, such as a carbon fibre electrode element of a Pb-acid battery, comprises pressure impregnating into the fibre material an electrically conductive lug material, such as molten Pb metal, to surround and/or penetrate fibres and form an electrical connection to the fibre material and provide a lug for external connection of the electrode element. Other methods of forming a lug for external connection are also disclosed.

In the present invention, a flat emitter is formed from emitter material preforms shaped as thin sheets of the emitter material. These sheets are subjected to various levels and/or amounts of mechanical working during their initial formation and are bonded to one another to create a preform having the desired thickness. The preform including the bonded sheets is subsequently worked to shape the preform into the desired configuration for the emitter. The working of the sheets of emitter material utilized to create the preform and the working of the preform to form the emitter provide a highly creep-resistant emitter that significantly improves the operation and useful life of the resulting emitter.

A diffusion-bonded heat exchanger (100) includes a core (1) in which a first heat transfer plate (10) and a second heat transfer plate (20) are stacked and diffusion-bonded to each other, a plurality of pairs of first ports (2), and second ports (3). The first heat transfer plate (10) includes a plurality of first fluid passages (11).

A method for the manufacturing of an object. The method includes receiving a desired alloy composition for the object, depositing a plurality of foils in a stack to form the object, applying heat to the stack at a first temperature to bond the plurality of foils to each other, and applying heat to the stack at a second temperature to homogenize the composition of the stack. The homogenized stack has the desired alloy composition.

An ultrasonic horn (50) includes: a vibration source part (53) to which an ultrasonic vibrator (58) is mounted; a tip end part (56) to which a capillary (18) is mounted; and an intermediate part (54) which is interposed between the tip end part (56) and the vibration source part (53) and propagates vibration generated by the ultrasonic vibrator (58) to the tip end part (56). The intermediate part (54) is formed with a single spiral hole (68) which is a hole penetrating in a radial direction of the ultrasonic horn (50) and advances in an axial direction as the spiral hole advances in a circumferential direction.

A PTC heating device has a frame surrounding an accommodation space, at least one PTC element accommodated in the accommodation space, and conductor elements, which are connected to the PTC element in an electrically conductive manner and enclose the PTC element between them. Each of the conductor elements is surrounded by a frame segment. The frame segments are welded together to enclose the PTC element in the accommodation space. In the method according to the invention, injection molded plastic frame segments having interacting connection segments are connected to conductor elements. At least one PTC element is then introduced between the frame segments. The frame segments are approached to each other until the connection segments abut against each other. The connection segments are then melted. As a result of this melting, the frame segments are approached further to each other until the conductor elements abut against the PTC element.

The invention relates to a method for producing a plug-in connector, and to a plug-in connector comprising a first tubular component and a second tubular component, and also a first connection geometry and a second connection geometry. A method for producing a plug-in connector is to be made available that permits an easier modification of the relative angle between the longitudinal axes of the two components in the finished plug-in connector. To this end, the two connection geometries are arranged in a connection plane inclined with respect to the longitudinal axes, such that the relative angle between the longitudinal axes can be modified by rotating the components. After a relative angle has been selected, the two connection geometries are connected by integral bonding.
