Patent CA-2093635-C (CA)
Title: Magnetron sputter coating method and apparatus with rotating magnet cathode
Inventor: HURWITT STEVEN D
IPC: C23C14/35
Filed: 1991-10-16
Granted: 2001-07-03
Abstract: A target (40), of a thick-ness that varies across its radius according to the amount of ma-terial required to be sputtered, is supported in a nest (42) in a chamber (10) of a sputter coat-ing apparatus. A closed loop permanent or electromagnet strip (80), preferably a flexible permanent magnet, is fixed to a magnet carrier (55) that rotates behind the nest about the target center axis. Portions of the magnet are near the rim of the target and portions are near, but not on, the target center.   One pole of the magnet faces the target rim and one faces the target center axis so that its field will enclose the target rim within a magnetic tunnel that traps a plasma over the target. Lumped magnets (90, 91, 92) across the center from the strip support the plasma near the center so as to cause some sputtering at the target center. Other lumped magnets (95, 96, 97, 98) adjacent the strip help sharpen the field so that a desired distribution of sputtering can be achieved. Enclosed in a sealed space (44) behind and in thermal contact with the target nest is the carrier from which the magnets project to facilitate the flow of cooling fluid across the back surface of the nest to cool the target as the carrier rotates.

Abstract: A simple and effective biochemical process solves the problems associated with sulfur in bitumen by removing sulfur from active participation in SO x-producing combustion reactions. In one aspect, an emulsion of bitumen and water is contacted with a microbiological desulfurization agent for a time and under conditions effective to reduce the oxidizable sulfur con-tent of the bitumen. The preferred agents do not affect the heating value of the fuel, but selectively oxidize organic sulfur to water-soluble sulfates which can either be physically removed or chemically bound so that they do not cause SO x produc-tion. Multistage reaction is employed to enhance sulfur removal.

Title: Method of forming single-crystalline thin film
Inventor: YOSHIDA NORIYUKI
IPC: C30B23/02
Filed: 1993-07-26
Granted: 1998-09-15
Abstract: Disclosed herein is a method of forming a single-crystalline thin film having excellent crystallinity on a base material without depending on the material for and crystallinity of the base material.  In this method, a base material is provided thereon with a mask which can prevent chemical species contained in a vapor phase from adhering to the base material.  The base material is continuously moved along arrow A, to deliver a portion covered with the mask into the vapor phase for crystal growth.  Thus, a thin film is successively deposited on the portion of the base material, which is delivered from under the mask, from the vapor phase.  A crystal growth end is formed on a boundary region between a portion of the base material which is covered with the mask and that which is exposed to the vapor phase, so that a crystal having the same orientation as the growth end is grown on a portion of the base material newly exposed by the movement.

Abstract: An annular safety system for a well produced by gas lift includes a packer,  a landing nipple below the packer and an operating seal unit to which primary and secondary well tubings and a control line are connected.  There is an inline valve in the secondary tubing and safety valve operated by the control line in a primary flow conduit in the operating seal unit.  After the operating seal unit  is  inserted through the packer to automatically land and be locked in the landing nipple and the packer operated to anchor and seal  in a well casing,  flow passages are formed for conveying lift gas from the secondary tubing to around the landing nipple for lifted flow upward through the primary conduit and tubing.  When the well is being produced by lift gas, and pressure in the control line is reduced purposely or by rupture of the control line, the safety valve operates to prevent upward lifted flow in the primary tubing.          If lift gas pressure in the secondary tubing is reduced purposely or by rupture,  the inline valve prevents upward flow.   The operating seal unit may be unlocked from the landing nipple for retrieval from the packer and well.

Granted: 2002-01-22
Abstract: A rechargeable battery is charged by connecting the terminals of the battery to an electrical power source. In order to avoid overcharging and undue temperature increase in the battery cell, the course of at least one charging parameter is surveyed during at least part of the process of charging the battery. This charging parameter surveyed is compared with a number of reference par-ameter courses representing idealistic or desirable processes of charging the battery for different starting states of the battery. In order to determine the starting state of the battery and thus selecting a reference parameter course, the battery may initially be test charged for a short period of time and subsequently test discharged for another short period of time. The comparisons may for example be made by means of a microprocessor, which may also select the reference course. Thereafter the process of charging the battery may be controlled so as to approximate the course of said charging parameter to the selected reference course. The in-vention also relates to a method of determining characteristic parameters of the battery which may be used to control a subse-quent charging process. Such characteristic parameters may be the capacity of the battery, the maximum charging temperature and the maximum charging voltage. The invention further relates to a battery and a battery system wherein the battery may com-prise information means for storing battery information. Such information means may for example be an electronic memory or a microprocessor.
