Patent EP-0092354-A2 (EP)
Inventor: MCMAHAN MICHAEL EDDIE
IPC: E21B34/12

Abstract: A recloseable circulation valve especially for use in oil wells and the like, includes a cylindrical housing (26) having a central flow passage (28) disposed therethrough and having a power port (30) and a circulation port (32) disposed through a wall thereof. An operating mandrel (34) is telescopically received in the upper end (40) of the housing. A valve sleeve (48) is slidably received in the housing and movable to open and close the circulation port. A power mandrel (50) is disposed in the housing and is connected to the valve sleeve for moving the valve sleeve from an initial position toward an open position. A mandrel lock (72) is provided for locking the operating mandrel and power mandrel together after the power mandrel moves the valve sleeve from its initial position. The power mandrel and valve sleeve are initially held in their initial positions by a shear pin (64) assembly. After the power mandrel moves the valve sleeve upward toward its open position, and the power mandrel is locked to the operating mandrel by the mandrel lock, the circulation valve may be subsequently repeatedly opened and closed by picking up weight from, or setting down weight, on the circulation valve. Methods of testing and treating subsurface formations utilizing such a circulation valve are also described.

Abstract: In a method of manufacturing pure green light emitting diodes, after an n-type GaP epitaxial layer with thickness larger than or equal to a value for which the density of dislocation on the surface becomes less than or equal to 1 x 10" cm -2  is grown on an n-type GaP substrate, a p-type GaP epitaxial layer is grown on the above n-type epitaxial layer. Even with the use of a GaP substrate with normal dislocation density, the density of dislocation in the neighborhood of the p-n junction becomes low and therefore GaP green light emitting diodes with high intensity of light emission is obtained.

Abstract: This arrangement enables audio signals to be transmitted between a number of interconnected subscriber stations via a power transmission system used as the transmission line. The audio signals are transmitted by frequency modulation of a carrier frequency. Control signals required for controlling audio signal transmission and for switching connections between subscriber stations are transmitted by amplitude modulation of the same carrier frequency. This means that only one carrier frequency channel is occupied and only one carrier frequency needs to be generated. <IMAGE>

Abstract: A method of producing a flat polymeric yarn is disclosed which includes the steps of melt spinning a polymer to form a plurality of running filaments, combining the filaments to form a running bundle of filaments, and then guiding the running bundle into contact with a ribbon of fluid so as to apply a controlled quantity of the fluid to the bundle. The fluid coated bundle is guided over a plurality of serially arranged curved braking surfaces, and it is then withdrawn by means of a draw roll so as to draw the running bundle to an extent which exceeds its plastic limit. The application of the fluid to the bundle in accordance with the present invention results in a hydrodynamic friction, rather than a sliding contact friction, between the bundle and braking surfaces, and produces yarn of very uniform quality while also avoiding wear of the braking surfaces.

Abstract: A test site for gauging the adhesion between the insulating layers and the metal layers used to produce the various devices on a semiconductor chip. The chip-sized test site can be formed along with the product chips on the product wafers. The layers of the test site are arranged such that a first polyimide layer (16) forms a first test interface with a silicon nitride layer (12) and a second test interface with a first metal layer (14A, 14B), and a second polyimide layer - (20) forms a third test interface with a second metal layer - (18A, 18B), a fourth test interface with the first polyimide layer (16), and a fifth test interface with the silicon nitride layer (<sub>1</sub>2). These five interfaces form a single continuous adhesion test interface (ATI). During a 90° peel test, the layers of the test site will sequentially separate along this interface (ATI). Thus, the adhesion at five different interfaces can be tested during a single peel test on a chip-sized test site.
