Title: Method of manufacturing active matrix display device using insulation layer formed by the ale method
Inventor: NASU YASUHIRO
IPC: H01L21/316
Filed: 1990-03-07
Granted: 1996-08-27
Abstract: There is disclosed a method of manufacturing an active matrix display device, in which particular emphasis is laid on the forming step of an insulation layer by the ALE method.  The insulation layer can be a gate insulation layer, an inter-busline insulation layer, a protection layer or an auxiliary capacitor insulation layer of the display device.  The method of forming the insulation layer comprises a predetermined number of repeated cycles of the steps of subjecting a substrate to the vapor of a metal inorganic/organic compound, which can react with H2O and/or O2 and form the metal oxide, under molecular flow condition for the duration of depositing almost a single atomic layer, and next subjecting the surface of the thus formed metal inorganic/ organic compound layer to the H2O vapor and/or O2 gas under molecular flow condition for the duration of replacing the metal inorganic/organic compound layer to the metal oxide layer.  The subsequent steps after forming of the insulation layer include deposition steps of silicon nitride and amorphous silicon layers using the same plasma CVD apparatus.  The molecular flow condition is obtained by maintaining the pressure in a reaction chamber within a range between 1 and several tens of milli-Torr.          The invention reduces defects such as cracks and pinholes and increases the electrical breakdown voltage.

Title: Method and apparatus for dynamic and interdependent processing of inbound calls and outbound calls
Inventor: SZLAM ALEKSANDER
IPC: H04Q3/58
Filed: 1991-05-06
Granted: 2000-10-03
Abstract: A method for optimizing the pacing and processing of inbound calls and outbound calls. Statistics are generated concerning inbound calls and outbound calls, and concerning the performance of each agent for inbound calls and outbound calls. Separate statistics concerning inbound calls and outbound calls allow a more accurate prediction of call pacing and handling requirements and of the availability of an agent so as to maximize the productivity of each agent and control the on-hold time of inbound and outbound calls.      Each trunk line is designated for inbound calls or outbound calls and the status of each trunk is monitored. If all of the trunks allocated to inbound service are in use then some of the trunks designated for outbound service are redesignated for inbound service. If more than a predetermined number of trunks designated for inbound service are not in use then some of these trunks will be redesignated for outbound service. Therefore, the rate of answering of inbound calls and the rate of placement of outbound calls, and the allocation of trunks between inbound calls and outbound calls are driven by the frequency, duration and number of calls and user-selectable options.

Title: Heating system with safety features
Inventor: HANSON LARRY G
IPC: B60H1/03
Filed: 1991-08-06
Granted: 1995-01-31
Abstract: In a large vehicle,  such as a bus,  a fuel-fired coolant heating system.  The heating system uses a heating unit to add heat energy to the coolant, which is then circulated to heat exchangers throughout the vehicle.  Safety features in the system include an impact switch which immediately stops the flow of fuel to the heating unit in the event of an accident.  Another feature which contributes to safe operation of the system is the presence of a deaeration tank in the coolant flow path.  The tank allows for the removal of air so that air locks can be prevented and is fitted with a pressure relief valve should overheating occur.  Finally, service and inspection of the system is facilitated by attaching components of the system to a slide panel, which can be pulled out of the side of the bus.  By making the components of the system easily accessible, problems are generally avoided and safety is, therefore, improved.  The heating unit for use with the present invention is one which is available from Espar Products, Inc., of Mississauga, Ontario, Canada, and is known as a D 12 W diesel-fired coolant heater having a capacity of 41,000 BTU per hour.          Safety features built into the Espar heater include a flame sensor and an overheat cutout switch.  The impact switch, deaerator tank and slide panel of the present invention are added safety features which make diesel-fired heaters usable in critical applications such as school buses.

Inventor: GREIFF PAUL
IPC: G01C19/5719
Filed: 1991-03-14
Granted: 2001-01-23
Abstract: A semiconductor chip gyroscopic transducer (10) is disclosed in which a semiconductor element (47) is supported in an outer element by a flexible linkage system which is in turn supported in a frame of semiconductor material (16) by another flexible linkage system which permits the element to vibrate about two axes relative to the frame. Balanced torque forces are provided by a system of buried (50, 52, 54, 56) and bridge (58, 60, 62, 64) electrodes. The stress and tension resulting from doping of these elements are released by a flexure beam (20, 22, 36, 38). The inertial mass of the inner element is balanced by formation in a central pit and on-chip electronics avoids the capacitive loading effects of long runs from high impedance sources. Flexure footings are integrated with the structure adding stability to flexures connecting the supported gyroscopic resonator element to the supporting structure, offsetting a rippling effect inherent in the oxide structure. Flexure grooves provide selective stiffness in the flexure. The bridge electrodes (58, 60, 62, 64) are additionally electrically isolated for electrical compatibility with gyroscope electronics.

Title: Plasma systems having improved thermal spraying
Inventor: MUEHLBERGER ERICH
IPC: C23C4/00
Filed: 1992-09-11
Granted: 1999-09-07
Abstract: Apparatus for delivering heated powder to the plasma gun of the thermal spray plasma system includes a hollow heater tube coupled between a powder feeder and the plasma gun and a power supply coupled between opposite ends of the heater tube.      The power supply heats the walls of the heater tube to a temperature below the melting point of the powder particles, to prevent melting and adhesion of the particles thereto. The length of the heater tube is selected to provide an adequate dwell-time of the powder particles therein for a given powder flow rate, so that even relatively large powder particles are heated to a temperature relatively close to that of the heater tube walls upon delivery to the plasma gun. The efficiency of the heater tube is improved by a water cooled reflector tube concentrically disposed about the outside of the heater tube, with oxidation of the tube surfaces being prevented by a flow of inert gas along the space between the heater and reflector rubes.      The heated powder delivery apparatus can be used by itself and without the plasma gun to effect thermal spraying in instances where the powder is of the type that can be heated close of the melting point without adhering or clogging. One or more ring-shaped electrodes and associated DC power supplies can be disposed within the plasma stream to provide additional powder particle heating and control within the plasma stream itself.
