Title: High contrast thin film electroluminescent display
Inventor: BUDZILEK RUSSELL A
IPC: H05B33/22
Filed: 1993-12-15
Abstract: A display system (25) includes an enhanced specularity multi-layer thin film electroluminescent (TFEL) panel (26) and circular polarizer filter (27) which combine to provide a high contrast TFEL display. The enhanced specularity is obtained by increasing the rate thc phosphor layer of the panel is deposited which results in a smoother, more specular surface. The increased specularity of the panel (26) provides a darker display background, and therefore higher contrast.

Patent CA-2155058-A1 (CA)
Inventor: LEUNG KIN K
IPC: H04M3/00
Filed: 1995-07-31
Abstract: A method and system for updating a replicated database in a foreign and home telecommunication network system to improve call setup time and system availability in a  foreign  region  for  roaming  customers  is  disclosed.          Customer records are updated in a visitor database contained in a foreign region within the signaling system of foreign telecommunications  network.   Information concerning the updated database record is transmitted from the visitor database through the signaling network of a home country to a home database which contains the replicated version of the visitor database record in the foreign region.  A field is added to the database record corresponding to a version number of the database record so as to identify the record referenced by queries of calls  in progress.   The home database record at the home country is changed to reflect changes in the visitor database at the foreign region by using the version number sequence while maintaining at all database sites the older version of the database record for query access until after completing the processing of all previous calls querying the database record.

Title: Modified plastic bottle injection blow-molding apparatus and process
Inventor: SALEMI TONY
IPC: B29C49/74
Filed: 1995-09-26
Abstract: In an injection blow-molding process the preform is purposely formed as a smooth walled tube closed at one end and without any thread or other cap attachment configuration about the mouth of the preform. The preform is moved to the bottle mold which completely forms the cap attachment configuration with the bottle in the blow-molding step. A processing dome is also formed from the preform in the blow-molding step to provide means to transfer the bottle to the trimmer which removes the dome. By using the smooth walled preform (without threads or any other cap fastening features), the bottle mold may utilize only a portion of the vertical height of the preform for the bottle. Bottle molds for a variety of bottle volumes and heights may employ the same preform and preform injection mold. The smooth walled preform also permits bottle molds with a variety of mouth diameters to be employed with the same preform injection mold. Since the bottle mold provides the specific cap attachment configuration of the bottle such as threads or lugs, the same preform and preform injection mold may be employed for a variety of cap attachment configurations, by using a common preform only the bottle mold need be manufactured for each new bottle configuration thereby saving the cost of a dedicated preform injection mold and the cost of set-up time for the preform injection mold. The bottle molds can comprise sets of modular mold parts for exchangeability. For an injection blow-molding machine that is to be employed to manufacture several different bottle configurations on a batch basis each year the savings in tooling cost are considerable and the savings in set-up costs, processing time and minimum product rejects with the new process and apparatus can also be considerable.      The new smooth-walled preform and preform injection mold apparatus and process is also applicable to the injection, stretch and blow-molding process for making bottles.

Title: Plasma shaping plug for control of sputter etching
Inventor: HURWITT STEVEN D
IPC: H01J37/34
Filed: 1994-04-08
Abstract: A re-entrant plug structure (52) is disclosed which extends inside a processing chamber (30) containing an ionized plasma (48) in proximity to the plasma (48) to physically displace the ionized plasma (48) and selectively controllably vary concentra-tion of ionized gas particles (15) over the surface of a wafer (40) to be sputter etched which is supported inside the chamber (30). The variation of concentration of the ionized plasma (48) allows the selectively controllable variation of sputter etch rates on the surface of the wafer (40). The re-entrant plug structure (52) may be formed as part of the enclosure cover (34) of the processing chamber (30) or may be a separable moveable unit which is inserted into the plasma through an opening in the pro-cessing chamber (30). The re-entrant plug (52) may be of various lengths, diameters and shapes to displace and shape the ionized plasma (48). In an alternative embodiment of the invention, the plug contains a permanent or electromagnet (80) which further magnetically displaces and shapes the plasma (48) in addition to the physical displacement caused by the re-entrant plug (52).

Patent CA-2169803-A1 (CA)
Inventor: LI JAY J
IPC: G01N33/96
Filed: 1996-02-19
Abstract: Provided is a method of preparing dye-based reference materials useful for calibrating or qualifying instrument systems that are diagnostic spectroscopically for hemoglobin and CO-ox fractions. The dye-based reference materials are non-proteinaceous and may be interpreted by CO-oximeter instrument systems as providing a spectrum substantially equivalent to the spectrum of blood, particularly with regard to  hemoglobin and hemoglobin CO-ox fractions.  Dye-based reference materials may be formulated to provide CO-ox fractions approximating those seen in a clinical setting, including normal physiological CO-ox fractions.  The dye-based reference materials may be combined with other ingredients thus making the materials useful as references for pH and blood gas instruments and/or electrolyte instruments in addition to CO-oximeter instrument systems.

Title: Magnesia coating and process for producing grain oriented electrical steel for punching quality
Inventor: MURPHY ROBIN A
IPC: C21D1/70
Filed: 1996-02-20
Abstract: The present invention provides an annealing separator composition for coating grain oriented electrical steel prior to the final high temperature anneal for secondary grain growth. The magnesia based coating contains at least 20% silica on a water free basis. The large silica additions limit the interface between the coating and the base metal and results in a thick glass which is easily removed.  The magnesia coating develops excellent magnetic properties and does not require the normal strong acid cleaning or special abrasive means to remove the glass film which forms.  The bare electrical steel, which may be coated to enhance the punching properties, has improved the die life because thehard glass film has been substantially removed.

Title: High-density read-only memory
Inventor: SHOJI MASAKAZU
IPC: G11C17/12
Filed: 1996-02-22
Abstract: A system and method for the storage of digital information wherein data that would normally be represented by multiple bits of information is effectively stored at single memory site within a ROM. This is accomplished by employing a multiple bit-line memory architecture, in conjunction with a data decoder.  With this arrangement it is possible to store, at a single memory site, information that would have required up to log2((n(n-1)/2)+1) individual memory sites in a conventional ROM (where n is the number independent of bit-lines connected to an individual memory element in the invention). The invention is particularly well-suited to what would be considered relatively low-speed data retrieval systems, such as those adapted to provide audio and/or video to a user on a real time basis.
