A circuit board element and production thereof are disclosed, whereby a noble metal is applied to a structured conductor layer on a circuit board substrate, comprising said conductor layer. The conductor layer is roughened on the surface, preferably after the structuring thereof and the noble metal applied as a layer, essentially on all of the structured roughened conductor layer, whereupon the noble metal layer surface is given a corresponding roughness.

摘要:
A seal (1) for a hydrostatic linear guide with a given adjustment direction (5), with a longitudinal seal section (7, 7′) extending essentially parallel to the adjustment direction (5), and with a transverse seal section (8, 8′) extending essentially transverse to the adjustment direction (5), wherein a first lip seal with a projecting lip portion (12) extends along the longitudinal seal section and a second lip seal with a projecting lip portion (14) extends along the transverse seal section. A height of the projecting lip portion (12) of the first lip seal oscillates in a wave shape in the adjustment direction. With such a seal (1), both a high degree of static oil tightness and also a high degree of dynamic oil tightness are achieved for a hydrostatic linear guide.

摘要:
A hydrostatic mounting of longitudinally displaceably arranged machine parts, which have pressure pockets for hydraulic fluid for building up a hydrostatic pressure between two machine parts, gaps for the hydraulic fluid which are adjacent to the pressure pockets and are delimited by gap faces of the two machine parts, drainage for the reception of hydraulic fluid, and at least one seal arranged between the machine parts and surrounding the drainage sealing against leakage of hydraulic fluid out of the hydrostatic mounting. At least one circumferential portion of the seal has an outer sealing lip and an inner sealing lip. The inner sealing lip is adjacent to the gaps, and a vacuum-loadable drainage portion of the drainage is arranged between the two sealing lips.
摘要:
Linear roller bearing, for carriage (1) which is longitudinally displaceable along rail (2). Carriage (1) has an endless channel (8) for endless circulation of rolling bodies (9). Channel (8) has load section (10), return section (11) and two deflection sections (12) which connect load section (10) to return section (11). Rolling bodies (9) roll in load section (10) on raceways (10a, 10b), and returned, without load, in return section (11). Bodies (9) are deflected in deflection sections (12) between load section (10) and return section (11). Deflection sections (12) have one inner deflection means (14) with inner deflection race (16) and outer deflection means (13) with outer deflection race (15). Inner deflection means (14) and outer deflection means (13) are connected, integrally to one another.
摘要:
A machine for producing a knitted product by at least partly using untwisted fiber material (4) includes at least one stitch forming system, on which stitch-forming elements (3) can be brought into a fibre pick-up position. A thread guide (27) is associated with the stitch-forming system and has a passage (30) for the fibre material (4). A drafting assembly (9) is associated with the stitch-forming system for attenuation of the fibre material and a spinning device (15), which is arranged between the drafting assembly (9) and the thread guide (27) and contains at least one spinning element (16) working with a blast air flow and a transport tube (17) connected thereto. The transport tube (17) contains an outlet end (17d) for the fibre material opening into the thread guide (27). The outlet end (17d) has an inner cross-section (D2), which is exactly the same size as or smaller than an inner cross-section (D1) at an outlet end of the passage (30). The intensity of the blast air flow is selected such that this is sufficient at least to securely transport the fibre material (4) as far as the stitch forming elements (3) without further auxiliary means.
