Title: Medicament auto-injector with slidable needle sheath - which actuates injection drive only when needle has penetrated to required depth
IPC: A61M/
Filed: 1992-11-19
Granted: 1996-01-25
Abstract: A medicament auto-injector comprises a cylindrical body (1) to receive a prefilled syringe (4) and with an upper end collar forming a seat for the syringe head. A tubular slide (5) is movable on a cylindrical surface of the body, one having a bevelled projection and the other a shoulder (11) between which is a resilient ring (9) to prevent mutual reciprocation so that the slide covers the entire syringe needle (10).

Title: Top guide device for sliding doors
IPC: E06B3/46
Filed: 1993-01-28
Granted: 1996-09-09
Abstract: A guide device is described for the top guides of sliding doors, consisting of a support frame attached to a pair of perpendicular arms able to slide freely in supports attached to the frame in the place where the doors are placed, the frame proper being able to move forward and back by advancing along said arms. At the opposite surface to that where the aforesaid arms are attached, the frame has channels which accommodate linear guides, integrated with the doors, which by means of ball bearings and rollers allow the doors themselves to be opened. Thus, when the doors are opened, they follow the profile they will follow the diverging one of the lower guides, and the upper frame protrudes outward, and when the doors are closed the contrary will occur, that is, the frame will disappear.

Title: Multilayer epitaxial structure and method for fabricating same
Inventor: JOSEPH CHAN
IPC: H01L21/205
Filed: 1993-04-17
Granted: 1994-05-01
Abstract: An all epitaxial process performed entirely in a CVD reactor is employed to grow heavily doped layer on lightly doped layer on a heavily doped substrate, eliminating the need for separate diffusion, even for high impurity concentrations. The process starts with a heavily doped silicon substrate of carrier concentration typically greater than 1*10^19 per cm^3. To minimize outdiffusion, the substrate is "capped" by growing very thin and heavily doped silicon layers which are depleted by hydrogen purges. A first epitaxial layer is grown over the "capped" substrate. This layer is relatively lightly doped, having a resistivity of more than 200 ohm.cm. A second epitaxial layer is then grown over the first epitaxial layer. The second epitaxial layer has a polarity opposite to that of the substrate and is heavily doped to a resistivity of less than .005 ohm cm.
