Patent CA-2040396-A1 (CA)
Inventor: FISHBEIN BRUCE J
IPC: H01L29/51
Filed: 1991-04-15
Abstract: An insulated gate field-effect transistor or similar semiconductor-insulator-semiconductor structure has an increased time-dependent dielectric failure lifetime due to a reduction in the field across the gate insulator. The electric field in the gate insulator is reduced without degrading device performance by limiting the field only when the gate voltage exceeds its nominal range.  The field is limited by lowering the impurity concentration in a poly-silicon gate electrode so that the voltage drop across the gate insulator is reduced.  In order to avoid degrading the device performance when the device is operating with nominal voltage levels, a fixed charge is imposed at the interface between the gate electrode and the gate insulator, so at a gate voltage of about the supply voltage level the response changes to exhibit less increase in the drop across the gate insulator for higher voltages.  Also, the impurity level in the gate electrode may be low enough so that the gate is in deep depletion for transient increases in gate voltage, thereby limiting the drop across the gate insulator.

Title: Detecting and imaging in biochemical assays using phosphor screens
Inventor: BERS GEORGE
IPC: G01N21/76
Filed: 1991-05-31
Abstract: Immobilized macromolecules such as proteins or nucleic acid sequences are tagged with labels which induce a chemiluminescent reaction in a liquid-phase substrate.  As the reaction is occurring, the substrate is exposed to a phosphor screen which absorbs the chemiluminescent emission in an image of the pattern formed by the macromolecules.  The absorbed energy is then released and read, providing qualitative and optionally quantitative information regarding the immobilized macromolecules.

Title: Method for guaranteeing data stored in a primary and secondary data base in a process control system
Inventor: MCLAUGHLIN PAUL F
IPC: G06F15/16
Filed: 1991-09-18
Abstract: Data bases of a first and second input output processor (IOP), which are primary and secondary slave IOPs, respectively, are synchronized, and communications by a master controller is made only to the first IOP.    Each IOP is executing the same tasks utilizing their own clocking systems.  A method for guaranteeing that the first and second data base remain synchronized comprises the steps of communicating a message to the first IOP to update the first data base.  The second IOP eavesdrops on the communications, and when the second IOP recognizes that the message is to the corresponding primary slave IOP and that the first IOP has successfully received the message, accepts the message.  The first IOP and the second IOP execute the received message.  The master controller issues a status request type message to the first IOP, and then issues a status request type message to the second IOP.  The controller verifies that responses to the status requests indicate the update of the respective first and second data bases was completed identically, thereby providing information which permits the master controller to guarantee the first and second data base remains synchronized after the update operation.

Abstract: Stretch wrapping packaging material on a load includes introducing stretch wrap packaging material onto V shaped tips of projecting portions of a first grooved roller so that the packaging material spans the nonprojecting portions of the first grooved roller.  The web of packaging material and the first grooved roller are transported in the direction generally parallel to the grooves.  The web of packaging material spanning the nonprojecting portions of the first grooved roller is impinged with V shaped tips of projecting portions of a second grooved roller.  The tips of the projecting portions of the second grooved roller are transported at a speed which is less than the speed of the tips of the projecting portions of the first grooved roller. The tips of the projecting portions of the second grooved roller moves at a speed which stretches the web between the first and second grooved surfaces in a direction transverse to the direction in which it is transported and minimizes any stretching of the web in the direction in which the web is transported.  The web is stretched between the projecting portions of the first and second grooved rollers in a direction transverse to the direction in which the web is transported.  The web is separated from the first and second grooved surfaces and wrapped onto a load by providing relative rotation between the load and a dispensing mechanism for the web.

Title: Thin configuration flat form vacuum-sealed envelope
Inventor: LYNN JUDD B
IPC: H01J61/30
Filed: 1991-07-19
Abstract: A thin configuration flat form glass envelope for use in vaccum tubes, incandescent lamps, fluorescent lamps and other electronic devices having elements which operate in a partial vacuum. In certain embodiments the envelope is comprised of a flat wall plate (14) and shaped wall plate (12) having a plurality of spaced-apart ridges (16, 18, 20) which project toward and in juxtaposition with the flat plate (14). The side walls of the ridges converge at a predetermined included angle and merge at a sharp apex that contacts the flat plate along a narrow path which produces minimal degradation of brightness uniformity across the envelope when light is transmitted through the shaped plate. Between the ridges a plurality of channels (28, 30) are formed containing an ionizable medium which is energized by electrodes to produce UV light which in turn is absorbed by a phosphor coating to emit visible light.  In other embodiments the envelope is formed by two shaped plates joined together in facing relationship to form the channels.
