Patent EP-0321746-A1 (EP)
Inventor: CRITCHLOW DALE L
IPC: H01L21/768
Filed: 1988-11-30
Abstract: A method for forming a silicide bridge (e.g. 60A) between a doping region (e.g. 38B) and an adjacent poly-filled trench (24) separated by a thin dielectric (22). Silicon is selectively grown over exposed silicon regions under conditions that provide con­trolled lateral growth over the thin dielectric without also permitting lateral growth over other insulator regions. A refractory metal layer is then deposited and sintered under conditions that limit lateral silicide growth, forming the bridge. This process avoids the random fails produced by previous processes while enhancing the compatibility of bridge formation with shallow junctions, without introducing extra masking steps or other process complexities.

Abstract: Disclosed is an artifical lens adapted for implantation in the human eye and the method for implanting such lens. The lens (1) is of pliable material so that it may be folded or curled for insertion through a minimum length incision. It has a medial optic portion (2) having a posterior concave surface (2a) corresponding to the anterior surface (13c) of the natural lens (13) when the latter is in its flattest natural position and haptic portions (3, 4) for seating the lens in the eye such that the posterior concave surface of the medial optic portion of the artificial lens seats directly against the anterior surface of the natural lens of the eye which remains in and is not removed from the eye. The method according to the invention includes determining the shape of the anterior surface of the natural lens when the latter is in its flattest natural position, forming the posterior surface of the optic of the artificial lens such as to correspond substantially to that shape and seating the lens in the posterior chamber between the iris and the natural lens with the posterior concave surface of the artificial lens seated on the anterior convex surface of the natural lens.

Abstract: When shock waves (20) pass through liquids, cavitation bubbles (22) may occur which accumulate at the surface and result in undesirable destruction. In order to prevent such destruction, it is therefore necessary to detect and analyse the occurrence of cavitation. This is also particularly necessary in lithotripsy at places where access is difficult, for example in a patient's body. According to the invention, therefore, an optical measuring device embodying an optical waveguide (8) with a free end (10) is provided which comprises a control and evaluation circuit (5) for detecting a cavitation signal produced by the accumulation of cavitation bubbles (22) at the free end (10).

Abstract: So that cable forces can be determined in order to balance cable tensions and/or to determine the weights loading the cables, the suspension of the cables is guided via a measuring ring which is subdivided by apertures into an inner and outer bush in such a way that the inner bush is connected to the outer bush via essentially horizontally running bridges and is thus elastically held in this outer bush. Deformations of the bridges under the effect of forces transmitted from the inner bush to the outer bush can be determined by wire strain gauges allocated to the bridges just as if need be by electronic distance transducers monitoring the vertical distance between the bushes and effective in an inductive and/or capacitive manner. The cable forces detected in this way can be used for balancing the cable tensions, and it is also possible to monitor, if need be continuously, the respective total loading, applied weights or the like. <IMAGE>
