Patent EP-0476380-A1 (EP)
Inventor: EKLUND ROBERT H
IPC: H01L21/8222
Filed: 1991-08-28
Abstract: 5 n7 A self-aligned bipolar structure (11) for use on SOI (silicon on insulator) substrates is described. This structure does not require etching poly and stopping on single crystal silicon. This is also a process of forming a MOS transistor and a vertical, fully self-aligned bipolar transistor on an insulating substrate. The process comprises: forming an epitaxial silicon layer (16) on an insulator (10), and etching the epitaxial silicon (16) to form a bipolar mesa and a MOS mesa; forming an oxide surface on the mesas; opening an emitter contact region in the oxide surface of the bipolar mesa; opening an emitter contact region in the oxide surface of the bipolar mesa; depositing a layer of poly; applying and patterning an etch resist on the poly, thereby providing an exposed portion of the poly on the bipolar mesa; etching the exposed portion of poly using the oxide surface as an etch stop, the etching thereby forming an emitter contact (60) of unetched poly; etching an extrinsic collector portion (76) of the mesa to provide a recessed region; forming a collector-side emitter sidewall (74) and a base-side emitter sidewall (74) on the emitter contact; forming an extrinsic base, using the base-side emitter sidewall to align the extrinsic base (72) to the emitter contact (60); and forming an extrinsic collector (76) in the recessed region using the collector-side emitter sidewall (74) to align the extrinsic collector (76) to the emitter contact (60).

IPC: E05D11/10
Filed: 1991-09-09
Abstract: The invention relates to a spring-actuated hinge, the spring of which is tensioned during the opening of the door and assists the closing operation. Known hinges have holding forces which are too low in the closed state. The invention eliminates this defect by accommodating in the hinge tab (2) springs (5, 6), the legs (5a, 6a) of which act in a controlled manner on control cams (1e, 1f) on the hinge block (1). The shape of the control cams makes it possible to press the door out of a stable open position up against the closing strips with great force. <IMAGE>

Abstract: A can end double-seaming machine has a housing in which a shaft (6) is rotatably supported. The shaft with a seaming cam lever (c) mounted is pressed downwardly by a presser (5) against the bias of a spring (e) until the lower surface of the seaming cam lever is held against the upper surface of the housing (a). Then, an annular spacer (4) is fitted over the lower end portion of the shaft underneath, with the tubular support (6) held against a neck (bx) of the shaft. A seaming roll lever (d) is then mounted on the lower end portion of the shaft. The presser is inactivated to release the shaft, which is lifted together with the seaming cam lever, the annular spacer, and the seaming roll lever under the bias of the spring until the marginal portion (2a) of the annular spacer abuts against the lower surface of the housing. The tubular support enters the housing by a distance corresponding to a predetermined clearance. The seaming cam lever and the housing are now spaced from each other by the predetermined clearance (a).

Abstract: A process for the manufacture of improved water soluble polyaminopolyamide-epichlorohydrin resins is disclosed. The polyaminopolyamide-epichlorohydrin reaction is continued until between 70% to 100% of the total charge of epichlorohydrin has reacted. The polyaminopolyamide-epichlorohydrin mixture is then treated with a specified amount of a halogen-free mineral acid. Preferably the mineral acid is selected from the group consisting of sulphuric acid, phosphoric acid, nitric acid and sodium hydrogen sulphate. Following the completion of the acid addition the reaction is continued to effect at least a 10% reduction in the polymer bound organochlorine concentration, based on the composition of the reaction mixture at the time of the acid addition.

Abstract: Masking is produced on the preform along the location of one or of each of the fold or separation lines (451 to 456), in order to oppose the infiltration of the constituent material of the matrix into the or each masked zone of the preform, so that after densification of the preform by chemical infiltration in vapour phase and removal of the masking, the or each masked zone of the preform forms a flexible connection integrated into the densified preform. The masking of the preform is advantageously preserved during a first densification phase until the parts (401 to 407) of the unmasked preform are consolidated, then the masking is removed to obtain flexible connections integrated into the consolidated preform, allowing the latter to be brought to a form corresponding to that of the component to be produced by folding along the lines corresponding to the flexible connections, and the densification is continued. In an alternative form, the masking may be removed only after the end of the densification to obtain a composite article with one or more articulation lines.
