Hydrogen purification devices and their components are disclosed. In some embodiments, the devices may include at least one foil-microscreen assembly disposed between and secured to first and second end frames. The at least one foil-microscreen assembly may include at least one hydrogen-selective membrane and at least one microscreen structure including a non-porous planar sheet having a plurality of apertures forming a plurality of fluid passages. The planar sheet may include generally opposed planar surfaces configured to provide support to the permeate side. The plurality of fluid passages may extend between the opposed surfaces. The at least one hydrogen-selective membrane may be metallurgically bonded to the at least one microscreen structure.

A vaporizer device for an inhaler comprises at least one electric vaporizer for vaporizing liquid fed to the vaporizer, wherein the liquid is transported by capillary forces from an inlet side through at least one liquid channel to an outlet side, where vaporized liquid can be added to an air stream, a carrier retaining the vaporizer, and at least one electrical line electrically contacting the vaporizer. The electrical line comprises a planar contact area, and the vaporizer and the planar contact area of the electrical line are materially and electrically conductively bonded to each other.

A substrate stacking apparatus that stacks first and second substrates on each other, by forming a contact region where the first substrate held by a first holding section and the second substrate held by a second holding section contact each other, at one portion of the first and second substrates, and expanding the contact region from the one portion by releasing holding of the first substrate by the first holding section, wherein an amount of deformation occurring in a plurality of directions at least in the first substrate differs when the contact region expands, and the substrate stacking apparatus includes a restricting section that restricts misalignment between the first and second substrates caused by a difference in the amount of deformation. In the substrate stacking apparatus above, the restricting section may restrict the misalignment such that an amount of the misalignment is less than or equal to a prescribed value.

A core-wire exposed portion in an electric wire and at least one pair of pressure-welding pieces made of an electroconductive material are included. The core-wire exposed portion is a portion is which a core wire composed of a plurality of element wires is exposed. The pair of pressure-welding pieces are provided with a core wire pressure-welding section in which pressure-welding end surfaces are disposed facing each other at a distance and Kate the core-wire exposed portion press-fitted between the pressure-welding end surfaces. The core wire pressure-welding section is formed as a section that brings all of the element wires in the core-wire exposed portion, between the pressure-welding end surfaces, into contact with either of the pressure-welding end surfaces while being in an aligned state.

A movable optical unit configured to be rotatable around an axis by an electromagnet includes a fixed shaft, a bearing through which the fixed shaft is inserted and which is polarized in a direction orthogonal to a long axis of the fixed shaft, a holding frame that is provided to be rotatable around the fixed shaft and holds at least one optical member, and a pair of arm members extending outward from the holding frame in a direction orthogonal to the long axis of the fixed shaft, the pair of arm members being bonded to the bearing in a state of sandwiching the bearing in a direction along the long axis of the fixed shaft.

Embodiments of golf club face plates with internal cell lattices are presented herein. Other examples and related methods are also disclosed herein.

The disclosure relates to a brazing method for joining substrates, in particular where one of the substrates is difficult to wet with molten braze material. The method includes formation of a porous metal layer on a first substrate to assist wetting of the first substrate with a molten braze metal, which in turn permits joining of the first substrate with a second substrate via a braze metal later in an assembled brazed joint. Ceramic substrates can be particularly difficult to wet with molten braze metals, and the disclosed method can be used to join a ceramic substrate to another substrate. The brazed joint can be incorporated into a solid-oxide fuel cell, for example as a stack component thereof, in particular when the first substrate is a ceramic substrate and the joined substrate is a metallic substrate.

A liquid chromatography apparatus includes a diffusion-bonded separation column comprising a lower substrate comprising titanium, an upper substrate comprising titanium, and a titanium patterned foil disposed between the lower substrate and the upper substrate. The lower substrate, titanium patterned foil, and upper substrate are diffusion bonded together to form a fluid path extending from an inlet port to an outlet port, wherein walls defining the fluid path within the diffusion-bonded separation column include a titanium surface coating.

A system for securing first and second metal workpieces to a central metal workpiece located therebetween. The system includes clamps to secure the first and second metal workpieces in coaxial alignment with the central metal workpiece, which is rotatable about its axis. Heating elements heat opposed ends of the first metal workpiece and the central metal workpiece, and opposed ends of the second metal workpiece and the central metal workpiece, to a hot working temperature. While the opposed ends are at the hot working temperature, the opposed end of the first metal workpiece is urged against the end opposed thereto of the rotating central metal workpiece, while the central metal workpiece rotates. At the same time, the rotating central metal workpiece's end opposed to the second metal workpiece is engaged with the opposed end of the second metal workpiece. The workpieces are allowed to cool, for bonding the opposed ends.
