Patent EP-0200422-A2 (EP)
Inventor: FREEOUF JOHN LAWRENCE
IPC: H01L21/331
Filed: 1986-04-16
Abstract: The composition and doping profile of the emitter (4) produces an electron gas (16) in the base (3) adjacent a band offset heterojunction interface be- 'tween the emitter and the base. When a suitable bias is applied, the electron gas is confined adjacent to the interface by a low barrier (produced by layer 10). The kinetic energy of ballistic electrons crossing the base to the collector (2) is controlled to prevent intervalley scattering by an electrostatic barrier (7) that under influence of bias provides an essentially level conduction band in the portion of the base adjacent the collector.

Abstract: Disclosed is a process for etching semiconductor materials with a high etch rate against an insulator mask using a novel etchant gas mixture. The mixture consists of a fluorochlorohydrocarbon (e.g., CCl₂F₂, CHCl₂F₂, CCl₄ or CCl₃F), SF₆, O₂ and an inert gas (e.g. He). The preferred gas mixture contains 2/1 ratio of the fluorochlorocarbon to SF₆ and the following composition: 1-4 % of SF₆, 3-10 % of O₂, 74-93 % of He and 3-10 % of fluorochlorohydrocarbon. The etch rate of silicon (or silicide) against an oxide mask using this etchant gas mixture under normal etching conditions is high, on the order of 30-40. An impressive feature of the process is shape control of trenches by mere manipulation of the RIE system power.

Abstract: A spacer, such as is used, for example, for transmitting tensile force between a building wall and a wall element, for example a facade, placed in front of it, consists of a bar-shaped or band-shaped element made of spring material. Starting from one end of the spacer, this element is bent over a portion forming a part length of this spacer, in such a way that this portion projects in different directions radially above the longitudinal extension of the element. The spacer can be knocked with the abovementioned portion into a bore of the building wall, this portion then being held in the bore of the building wall by a clamping fit. A part length of the spacer projecting beyond the building wall is tied into the wall element placed in front of it. This provides in an especially simple way a bond between the building wall and preceding wall element which absorbs tensile forces. <IMAGE>

The object of the invention is to provide a directionally adjustable low-voltage lamp being able to be secured at any desired point on sheeting or boards so that the light cone from the lamp may be adjusted in any desired direction. This object is attained by that, that the holder of the lamp is made of two rotary discs which are separated from each other by an insulating disc and are made of electrically conducting material, the central pivot axis of the swivel joint being defined by an axial pin of electrically non-conducting material which is bearinged on the two sides in bearing members of electrically conducting material with a certain degree of axial preloading, and rods of electrically conducting material are secured in these bearing members, such rods being connected with an electrical supply and extending perpendicular to the axia of swivel of the swivel joint and the other ends of such rods being supported in holes in holding members with a frictional engagement so as to be freely rotatable and axially displaceable.

Abstract: The invention relates to a device for combining partial piles of book pages by laying one on another. The partial piles may be brought up alternately in an inclined position on a conveying chain. According to the invention, there is provided above the conveying chain a rotary rearranging apparatus. The rearranging apparatus carries a plurality of gripping systems each adapted to pick up one partial pile of book pages and, after rotation of the rearrangement apparatus through a 360 degree revoluion, deposits the partial pile of book pages beside an identical succeeding partial pile. During the 360 degree revolution of the rearranging apparatus, each gripping system is rotated about an axis parallel to the rotational axis of the rearranging apparatus such that the gripper systems continuously remain in an upright orientation with the grippers always projecting downwards at the lowest point of the gripping system. Before combination of any given partial pile of book pages with another partial pile, every such given partial pile may be rotated by the respective gripper system through 180 degrees about an axis extending at 90 degrees to the normal of the plane of the partial pile, and for this purpose every gripping system of the rearrangement apparatus is mounted so as to be rotatable about a vertical axis and, in a part of its orbital path of motion during the 360 degree revolution of the rearranging apparatus, is rotated through 180 degrees about this vertical axis.

Abstract: A method of making a cartridge-type fuse involves forming a subassembly comprising an inner insulating housing preferably made of a transparent glass material, end cap terminals at the ends of the housing and leads extending axially therefrom. A preferably transparent encapsulating body is molded around the inner housing which covers, seals and physically interconnects the exposed exterior surfaces of the inner housing, terminal means and a portion of each lead adjacent to the terminal means. The molding operation is preferably carried out by unwinding a roll (11) of the fuse subassemblies (A) having their leads (5) secured between a pair of carrier strips (10) wound up with the subassemblies into a roll and supported on a rotatable supply reel (12). The reel is unwound in intermittent steps to bring a predetermined number of the subassemblies between pairs of mold cavity-forming elements (18A, 18B) initially separated and then brought together around the fuse subassemblies to mold the encapsulating bodies (B) therearound. The completed encapsulated fuses carried between the carrier strips are then would upon a take-up roll (12') for storage or shipment to the ultimate user.
