Title: Expansion dovel
Inventor: LEIBHARD ERICH
IPC: F16B13/06
Filed: 1985-11-11
Granted: 1988-09-22
Abstract: An expansion anchor assembly for use in a borehole formed in a receiving material has a leading end and a trailing end relative to the insertion direction of the assembly into the borehole. The expansion anchor assembly includes a tie rod with an expansion cone at its leading end, an expansion sleeve through which the tie rod extends and a cone sleeve positioned around the expansion cone and between the expansion cone and the leading end of the expansion sleeve. The radially outer surfaces of the expansion cone and the cone sleeve each have a different cone angle. Due to the different once angle, when the tie rod is drawn into the expansion sleeve toward the trailing end of the assembly, the part with the smaller cone angle moves in the same direction into the expansion sleeve until it contacts a stop. Subsequently on continued inward movement of the tie rod, both the expansion cone and the cone sleeve are drawn into the leading end of the expansion sleeve and effect an increased expanding action.

Abstract: Described herein is an improved target for use in a pulsed induced plasma X-ray lithography system. The target is formed as a disk shaped base having a series of concentric grooves formed on the side thereof incident to the focused laser beam. A plurality of small holes are fabricated through the base to the facing wall of the groove against which the laser beam is focused and a film, of a polyimide or silicon nitride material, covers the hole. A thin layer of metal target material is then placed on the film aligned with each hole. The thickness of the metal is selected to be sufficient to allow the complete ablation of the material during the existence of the X-ray emitting plasma. In this manner, a minimal amount of debris, either in the form of molten droplets or evaporated metal material, will be generated. The angle of the incident, or facing, side of the grooves is selected to be at an angle so that both the laser beam optical elements and the X-ray mask are positioned in an area where few, if any, molten droplets of debris are emitted. Such an angle may be 45 DEG  with respect to the plane in which the target substrate is moved while placing different target areas in incident with the laser beam. Such a target also allows the angle at which the laser beam is focused at the target to be approximately 65 DEG  from the alignment of the focal spot on the target and the vertical line to the mask. This angle, in turn, allows a slower lens and less optical coating to be used on the optical elements beyond the lens. pg,8

Abstract: An expansion dowel assembly includes an expansion sleeve, an expanding member and a bolt for pulling the expanding member into the expansion sleeve. The expansion sleeve has a leading end and a trailing end with a bore extending between its two ends. At the leading end, the bore is conically shaped and converges toward the trailing end. From the trailing end of the conically shaped section, the bore is cylindrically shaped and extends toward the trailing end to another smaller diameter cylindrically shaped section of the bore. At the transition between the two cylindrically shaped sections there is a stop shoulder which limits the pulling-in action of the expanding member and the radial widening of the expansion sleeve.
