Method and device for producing an adhesive bond between a first component and a second component (optical element) for microlithography. The method involves: introducing the first and second components into a positioning device for changing the relative position between the first and second components, calibrating a first relative position, in which a distance between the first and second components has a first value defining a predefined adhesive gap, calibrating a second relative position, in which a distance between the first and second components has a second value greater than the first value, applying adhesive to the first component while the first and second components are at a distance greater than the first value, and setting the first relative position while forming the adhesive bond between the first and second components. Calibrating the first and second relative positions are carried out before the adhesive is applied to the first component.

A hand extruder, particularly for welding parts made of plastics, has a main body which supports an extrusion means for the extrusion of plastic material, an actuation means actuating the extrusion means, a heating means heating the plastic material, a preheating means preheating parts to be welded, and a control means controlling the hand extruder; a grip detachably connected to the main body by an interconnection means preset to pass from a coupling configuration, in which the grip is joined to the main body, to an uncoupling configuration, in which the grip is separated from the main body; the interconnection means has an electrical mating means of the plug-socket type electrically and detachably connecting at least part of the means supported by the main body to an electrical control means arranged on the grip.

A machine for the production of a stand up pouch from a web includes a film feed which moves the web at continuously at a constant speed through a punching station, a folding station, and a welding station. The welding station includes a pair of seal bars which are driven by a server motor at a speed equal to a speed of the web during the welding. The punch station includes at least one electromagnetic punch.

A method is provided for joining thermoplastic components. During this method, a skin is provided that is configured from or otherwise includes a skin fiber-reinforced thermoplastic composite. A support member is provided that is configured from or otherwise includes a support member fiber-reinforced thermoplastic composite. A shim is arranged at an interface between the skin and the support member. The shim is configured from or otherwise includes a shim fiber-reinforced thermoplastic composite. The support member is welded to the skin through the shim at the interface.

A sheet space-detecting device detects a space between a rear end of a preceding first fiber reinforced plastic sheet and a front end of a following second fiber reinforced plastic sheet in a conveyance path for fiber reinforced plastic sheets and includes: a light-detecting sensor that projects detection light on an area including the rear end of the first fiber reinforced plastic sheet, the front end of the second fiber reinforced plastic sheet, and a reference surface exposed from the space and receives reflected light thereof; and a spacer that supports the rear end of the first fiber reinforced plastic sheet and the front end of the second fiber reinforced plastic sheet in a state where the rear end and the front end are separated from the reference surface, in an area including at least a light-projected area on which the detection light is projected.

A heat sink for use in induction welding includes a number of tiles, wherein the tiles are electrically non-conductive and have a thermal diffusivity of greater than about 25 mm2/sec. A joint flexibly joins the tiles together.

A laminated body pressing apparatus, which can restrain damage of a first outer ridge portion or a second outer ridge portion of a positive electrode plate during roller-pressing and can restrain damage of a strip-shaped first separator of a strip-shaped negative electrode body on a positive electrode plate side, includes a first press roller, a second press roller disposed parallel to the first press roller and spaced apart from the first press roller by a roller gap, and a metal plate feeding unit to feed a strip-shaped metal plate extending in a conveyance direction to the roller gap. The apparatus roller-presses the positive electrode plate and the strip-shaped negative electrode body by the first press roller and the second press roller in a state where the strip-shaped metal plate fed by the metal plate feeding unit is placed on the positive electrode plate placed on the strip-shaped negative electrode body.
