Title: Reducing copper corrosiveness of organic polysulfides
Inventor: PEROZZI EDMUND FRANK
IPC: C07C321/14
Filed: 1992-03-06
Granted: 2003-10-14
Abstract: Reducing the copper corrosiveness of dihydrocarbyl polysulfides by treating them with an alkali metal-containing or alkaline earth metal-containing substance capable of dissolving elemental sulfur (e.g., sodium hydroxide or sodium sulfide).  The process is conducted in a liquid reaction medium composed of a mixture of water and at least one water-soluble alcohol. Experiments have shown that it is possible by use of this process to reduce the copper corrosiveness to a level below that exhibited by a product formed by treating the same initial dihydrocarbyl polysulfide in the same way but in a liquid medium composed solely of water.

Title: Capture/berthing system for spacecraft
Inventor: JOHNSON CALDWELL C
IPC: B64G1/64
Filed: 1990-10-30
Granted: 2003-09-23
Abstract: A method and apparatus for joining vehicles such as spacecraft is disclosed that utilizes a capture and berthing technique. The coup-ling apparatus comprises a first coupling unit (12) having a general-ly rigid extensible structure (34) that is mountable to a first spacecraft (14) and a second coupling unit (16) having a probe-like structure (80) mountable to a second spacecraft (18) which is cooperable with the extensible structure (34) to effect ve-hicle coupling. The first and second spacecraft are maneuvered so as to generally align the coupling appara-tus thereon, after which the extensi-ble structure (34) is extended to en-gage and capture the probe-like structure (80). Following capture of the second coupling unity by the ex-tensible structure (34), the extensi-ble structure (34) is subsequently re-tracted to effect berthing of the first and second spacecraft. Once the spacecraft coupling units have been captured and berthed in the forego-ing manner, they can be structurally joined by appropriate coupling apparatus.
Patent CA-2066002-C (CA)
Inventor: FUKUZAWA TADASHI
IPC: H01L21/338
Filed: 1992-04-14
Granted: 1996-01-30
Abstract: Disclosed  is  a  new  method  suitable  for  making  highly integrated quantum wire  arrays,  quantum dot arrays  in a single crystal compound semiconductor and FETs of less than 0.1 micron gate length.  This makes it possible to construct a high-performance electronic device with high speed and low power     consumption,     using     a     combination     of low-temperature-growth molecular beam epitaxy (LTG-MBE) and focused  ion  beam   (FIB)   implantation.    The   compound semiconductor  (GaAs)  epitaxial  layers,  which are made by LTG-MBE, are used as targets of Ga FIB implantation to make Ga  wire   or  dot   arrays.    Precipitation  of   arsenic microcrystals,  which  are  initially embedded  in  a  single crystal  GaAs  layer  and  act  as  Schottky  barriers,  are typically  observed  in  an  LTG  GaAs  layer.   A  thermal annealing process,  after implantation, changes the arsenic microcrystals to GaAs crystals if the arsenic microcrystals are in the region in which the Ga ions are implanted.  A wire-like shape free of As microcrystals then acts as a quantum wire for electrons or holes whereas a dot-like shape free  of  As  microcrystals  acts  as  a  quantum  dot.   The co-existence of Ga ions  and dopant ions,  which provides conductivity type carriers opposite to the conductivity type of the majority carriers of a channel region of an FET, provides the fabrication of very narrow junction gate region for any FET.
