摘要:
The present invention relates to an article whose surface has been at least partly sealed and to methods of its sealing, the sealing layer comprising a reactive melt layer and a coating layer. The invention provides a method of sealing at least part of the surface of an article, comprising the steps of: (a) applying a reactive melt layer based on polyurethane to at least one part of the surface of the article; (b) smoothing the reactive melt layer; and (c) applying a coating material to form a coating layer on the reactive melt layer, the coating layer being applied before the full curing of the reactive melt layer.

An apparatus that forms a source bushing, while comprehending the possible formation of electrically conductive films thereon, is disclosed. Such an apparatus may advantageously be used to isolate an ion source from other components within the ion implanter, as these components may be at different electrical potentials. In one embodiment, the source bushing is constructed from a material having a lower electrical resistance than is currently used. By constructing the bushing in this manner, the effects of the applied lower resistance films is reduced, as the change in effective resistance is reduced. In other embodiments, the source bushing is purposely lined with an electrically semiconducting material, so that the effects of the later applied lining are minimized. In either case, the electrical potential between the two devices that are being isolated by the bushing is more evenly applied across the bushing.

A swashplate-type pivot bearing, or an axial piston machine that has the swashplate-type pivot bearing, which ensure reliable operation. The swashplate-type pivot bearing for a hydraulic axial piston machine has a housing section, a swashplate section and a multiplicity of rolling bodies. The swashplate section is pivotably mounted in the housing section by the rolling bodies and the rolling bodies are arranged in a full-roller configuration and/or without a cage in at least one rolling body row. The swashplate-type pivot bearing also has at least one follow-up device for follow-up adjustment and/or synchronization of the rolling bodies, which is arranged and/or formed at an end of the rolling body row. The follow-up device is controlled by a slotted guide.

A swash plate pivot bearing is provided having roller bearing segments (15) arranged between a hollow cylindrical bearing surface (12) for a swash plate (10) in a housing (3) and a cylindrical bearing surface (11) on the swash plate (10), held in curved cages (17) whereby elements are provided for controlling the cages which prevent the cage (17) accommodating the roller body (16) from slipping out from the optimum position thereof in the pivot bearing. The cage control elements are integrated into the roller bearing segments (15) so that at least one roller body (23, 23.1, 23.2) of cylindrical form has a positive engagement with the hollow cylindrical bearing surface (12) and the cylindrical bearing surface (11). It is thus possible to prevent the escape of roller bearing segments (15) from the bearing gap (22) due to the effects of vibration.

A method for manufacturing a semiconductor wafer electrostatic clamp, comprising providing a mounting plate, forming an insulative layer on an insulating portion of the mounting plate, forming a first electrode on a first portion of the mounting plate, forming a second electrode on a second portion of the mounting plate, forming a first segment having a first conductivity over the first electrode, forming a first region having a second conductivity over the first segment that creates an n-p type composite, forming a second segment having a third conductivity formed over the over the second electrode, forming a second region having a fourth conductivity formed over the second region that creates an p-n type composite.
摘要:
A pivot bearing having a first bearing surface of hollow cylindrical design, at least in sections. Guided in the first bearing surface is a second bearing surface of hollow cylindrical design, at least in sections. Rolling bodies are arranged between the bearing surfaces. The pivot bearing also has a cage for guiding the rolling bodies, and a slide block to prevent the cage from slipping. A first grove is formed in the first bearing surface and a second grove is formed in the second bearing surface. The groves are inclined transversely with respect to the running direction of the rolling bodies. the opposite inclination of the groves has the result that, if the spacing between bearing surfaces is neglected, the grooves intersect. The sliding block is guided between the grooves. The cage has a recess that holds the sliding block permitting cage control.
