Title: Scheme for controlling transmission powers during soft handover in a cdma mobile communication system
Inventor: OHNO KOUJI
IPC: H04B7/26
Filed: 1997-05-21
Granted: 2000-08-29
Abstract: A scheme for controlling transmission powers during a soft handover in a CDMA mobile communication system, in which the receiving quality can always satisfy the reference quality even when a relationship between the receiving qualities at the base stations is reversed within the selective combination interval. In this transmission power control scheme, one radio channel among a plurality of radio channels is selected as a reference radio channel at the prescribed selective combination interval, and then a transmission power control is carried out at a prescribed transmission power control interval so that a receiving quality of the reference radio channel satisfies a prescribed reference quality, while not switching the reference radio channel within the prescribed selective combination interval.

Abstract: A drillstring terminating in an drill bit (3) is run into a borehole. A reduced solid content drilling fluid is pumped through the drillstring tubes and out the bit, wherein the drilling fluid impinges upon and disintegrates formation material in cooperation with the bit. An annulus fluid having a density greater than that of the drilling fluid is continuously pumped into the annulus (5) between the borehole and the drillstring, wherein the annulus fluid extends substantially from the surface to the bottom of the drillstring. Drilling fluid and cuttings resulting from disintegration of formation material are returned to the surface through a substantially unobstructed tubular passage (17) in the drillstring. The annulus fluid is maintained under a selected and controlled pressure in the annulus, wherein an interface is formed at the drill bit at which annulus fluid mixes with the drilling fluid and is returned along with the drilling fluid and cuttings, and drilling fluid is substantially prevented from entering the annulus.

Title: A method for making heteromultimeric polypeptides
Inventor: PRESTA LEONARD G
IPC: C07K14/73
Filed: 1996-02-05
Granted: 2009-11-17
Abstract: The invention relates to a method of preparing heteromultimeric polypeptides such as bispecific antibodies, bispecific immunoadhesins and antibody-immunoadhesin chimeras. The invention also relates to the heteromultimers prepared using the method. Generally, the method involves introducing a protuberance at the interface of a first polypeptide and a corresponding cavity in the interface of a second polypeptide, such that the protuberance can be positioned in the cavity so as to promote heteromultimer formation and hinder homomultimer formation.  "Protuberances" are constructed by replacing small amino acid side chains from the interface of the first polypeptide with larger side chains (e.g. tyrosine or tryptophan). Compensatory "cavities" of identical or similar size to the protuberances are created in the interface of the second polypetide by replacing large amino acid side chains with smaller ones (e.g. alanine or threonine). The protuberance and cavity can be made by synthetic means such as altering the nucleic acid encoding the polypeptides or by peptide synthesis.

Abstract: An intermittent gas-insufflation apparatus insufflates a quantity of gaseous fluid into a patient during exhalation intervals of the breathing cycle. A  valve assembly actuates between a closed state and an open state to prevent or allow gaseous fluid flow from a source of gaseous fluid to the patient. A sensor detects changes in breathing pressure and generates sensor signals characteristic of the changes in the breathing pressure. A controller receives and processes the sensor signals during either the inhalation or exhalation interval or both and is responsive within the exhalation interval to the sensor signals to actuate the valve assembly into the opened state so that the gaseous fluid flows from the source of gaseous fluid to the entrance into the respiratory system of the patient during the exhalation interval. Methods are also described for embodiments of the invention and for maintenance of blood-oxygen concentration for a patient receiving oxygen.

Abstract: A dual trip level ground fault interrupter (GFI) which is designed to trip or operate at a first relatively low personnel protection level of ground leakage current, and also at a second relatively high equipment protection level of grounded leakage current. The dual trip level ground fault interrupter is provided for a power line, having line conductors and a ground conductor, supplying electrical power to a load. The dual trip level GFI comprises first and second differential current transformers, each having a primary winding and a secondary winding. All of the line conductors for the load pass through the primary winding of the first differential current transformer.      All of the line conductors and the ground conductor pass through the primary winding of the second differential transformer. The ground conductor does not pass through the primary winding of the first differential current transformer. The first differential current transformer responds to the total ground leakage current, and is wound to achieve a trip voltage at a high equipment protection level of ground leakage current (e. g. 30 ma). The second differential current transformer responds to any leakage current not returning on the ground conductor, and is wound to achieve trip voltage at a lower personnel protection level of ground leakage (e. g. 5 ma).

Title: Uniform distribution monoenergetic ion implantation
Inventor: SARKISSIAN ANDRANIK
IPC: H01J37/32
Filed: 1998-10-01
Granted: 2004-12-14
Abstract: A system for implanting ions in an object which has three dimensional topology in a uniform or predetermined pattern is provided by the invention herein. The system includes a vacuum chamber defining an interior space. The interior space includes a first region adjacent to interior walls of the vacuum chamber. The first region being used primarily for plasma protection. The interior space of the vacuum chamber also includes a second region for ion acceleration and the second region is substantially surrounded by the first region. A potential distribution control grid defines the boundary between the first and second regions and the potential distribution control grid is pervious to the passage of ions from the plasma generated in the first region into the second region. An object to be implanted is placed at a predetermined position in the second region and when subjected to a negative voltage charge, draws ions through the potential distribution control grid from the first region into the second region and accelerates them in a uniform manner towards the object to be implanted. The accelerated ions are monoenergetic since they all have the same momentum. The system provides magnetic field to help confine the plasma in the first region but maintains the second region in a relatively magnetic field free state.

Abstract: On décrit un procédé et un appareil perfectionnés servant à enlever une matière condensable à partir d'un gaz. On fait circuler le gaz, dans l'ordre, d'abord à travers un refroidisseur, afin de refroidir ce gaz et condenser la matière condensable à partir du gaz, puis à travers un séparateur, afin de séparer le condensat du gaz, et enfin à travers un réchauffeur afin de le réchauffer. On fait passer une charge déterminée de fluide frigorigène dans un cycle fermé à travers le refroidisseur, afin de refroidir le gaz par absorption de la chaleur provenant de celui-ci et par évaporation, puis on comprime le fluide frigorigène gazeux à l'aide d'une unité de compression pourvue de moyens d'entraînement électriques, étape dans laquelle on ajoute à ce fluide frigorigène une certaine quantité d'énergie. Ensuite, on fait passer le fluide frigorigène gazeux, sous pression et chaud à travers un condenseur auxiliaire conçu pour enlever l'énergie ajoutée par l'unité de compression, afin d'obtenir une charge nulle, puis on fait passer le fluide à travers un réchauffeur pour le condenser encore davantage et transférer la chaleur au gaz sortant. On fait ensuite sortir le fluide frigorigène du réchauffeur et on le renvoie vers le refroidisseur, complétant ainsi le cycle fermé. On mesure la charge déterminée de fluide frigorigène de façon que le fluide frigorigène sortant du réchauffeur soit à l'état sensiblement gazeux quand il n'y a pas d'écoulement de gaz à travers ce réchauffeur et que la pression de ce fluide sortant du réchauffeur décroisse de manière générale lorsque l'écoulement de gaz à travers le réchauffeur augmente.
