Patent ES-449145-A1 (ES)
Title: Elimination of stacking faults in silicon devices: a gettering process
IPC: H01L21/318
Filed: 1976-06-23
Abstract: Described are procedures for fabricating silicon devices which prevent the formation and/or activation of stacking fault nucleation sites during high temperature processing steps, such as steam oxidation of silicon wafers. The procedures, which take place before such high temperature steps, include forming on the back surface of the wafer a stressed layer and then annealing the wafer for a time and at a temperature effective to cause the nucleation sites to diffuse to a localized region near to the back surface. Illustratively the stressed layer comprises silicon nitride or aluminum oxide. Enhanced gettering is achieved if, prior to forming the stressed layer, interfacial misfit dislocations are introduced into the back surface by, for example, diffusion of phosphorus therein. Following the gettering step(s) on the back surface, conventional procedures, such as growing epilayers and/or forming p-n junctions, are performed on the front surface of the wafer.
Patent ES-449986-A1 (ES)
Title: Methods of fabricating a connector with a perforable insulative liner
IPC: H01R43/00
Filed: 1976-07-21
Abstract: An open-ended, B-wire type of deformable connector has a thin, perforable insulative liner secured to the inner surface of the inner one of a pair of telescopically coaxially disposed metallic sleeves in accordance with several preferred liner assembly methods. The liner is positioned so as to overlie the distal ends of an array of insulation-piercing protuberances formed in the inner sleeve, and to extend continuously in both the circumferential and longitudinal directions at least to the perimeter of the array. During assembly, while the inner sleeve is being fabricated out of strip stock in a progressive manner, each liner in the form of a section of thin, plastic film stock is positioned on and firmly secured (such as by pressure bonding) to the partially fabricated planar sleeve section along at least the solid wall border regions thereof (surrounding the array of protuberances). As such, the assembled liner not only remains taut in the axial direction while overlying the distal ends of the protuberances of the fabricated sleeve, but presents no peripheral edge obstruction to inserted conductors, particularly at the open end of the composite connector as assembled. The preferred methods of assembling the liners are also advantageously conducive to high volume, automated manufacture, at minimal cost, as such assembly may be carried out sequentially with the work functions normally performed on the strip stock from which the inner sleeves are fabricated.

Filed: 1980-01-25
Abstract: The valve includes a fixed plate (2) through which passages (20) are formed and a moving plate (3) through ed which passages (30) are formed. The moving plate is disposed downstream from the fixed plate and is connected thereto by means (6) which allow it to move a short distance between an open position in which the ends of the passages of each of the plates are uncovered to allow the liquid to pass from the upstream side to the downstream side, and a closed position with the plates in contact with each other and in which the passages of each plate are stopped by the solid parts of the other preventing the liquid from flowing from the downstream side to the upstream side. In the open position, the flow axis of each fixed plate passage (20) coincides substantially with the flow axis of the associated passage (30) of the moving plate (3), thereby directing and centring the streams of liquid flowing through the fixed plate into the passages in the moving plate.

Title: Oceanic energy converter with bubble nozzle
IPC: F03B13/12
Filed: 1980-05-23
Abstract: PURPOSE:To prevent the escape of air in a pressure chamber by issuing bubbles from bubble nozzles for providing air-curtains. CONSTITUTION:When seawater current is conducted through a flow passage 18, an impeller 19 is rotated, and the air of a pressure chamber 17 is mixed into the seawater current as bubbles by the work of the impeller 19 to escape to the outside of a unit together with the seawater.

Title: Method and apparatus for relaxing knitted fabrics.
IPC: D06C7/00
Filed: 1982-11-03
Abstract: The method for relaxing knitted fabrics according to the invention uses humidity, heat and agitation of the fabric. Said agitation is caused by projecting the fast-advancing fabric against a rigid support on which the then nontensioned fabric piles up.

The movable element of projection is a movable belt turning over two cylinders of which one at least is a driving cylinder, whose driving speed can reach 600 meters/minute.

The interval between the intants of closure of the two switches represents the amplitude and rapidity of movement of the object. Slight displacements or vibrations will not cause both switches to close due to the distance separating them but sudden violent displacements caused by a bag being snatched will cause an alarm. - The switches may be constituted by interdigitated printed conductors on a circuit board, the spacing between the conductors being such as to allow them to be bridged by the conductive sphere. Various forms of electronic monitoring circuit are described to trigger an alarm device in response to the two switches being closed in response to violent movement of the conductive sphere, using bistable circuits. The path has zones of differing curvature to provide a variation of the movement sensitivity.  (4/55)
