Title: Method for deposition and etching of thin films for microelectronic applications
Inventor: CHAU TU T
IPC: H01L21/465
Filed: 1990-11-08
Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a method for deposition or etching of thin films for microelectronic applications. In particular, it relates to the low temperature deposition of high quality silicon dioxide thin films suitable for gate oxide in MOS technology for VLSI applications. The method solves the problems derived from the harmful effects of energetic particle bombardment and photonic radiation emanated from the plasma, while at the same time makes use of the active species generated in the plasma before they are significantly deactivated, resulting in the achievement of high quality oxide films with low bulk and interface defect densities as well as high breakdown strengths.

Title: Method and apparatus for developing heat within conductive materials
Inventor: SPENDLOVE MAX J
IPC: H05B6/10
Filed: 1990-11-19
Abstract: ABSTRACT OF THE DISCLOSURE An electrically conductive work-piece is rapidly heated by establishing a current flow in the work-piece that is the highest it can be without damaging circuit components. Such components include at least a transformer having a high-voltage, low-current primary winding and a low-voltage, high-current secondary winding and insulated cables connected to the secondary winding and terminated in one or more clamps that attach to the work-piece. The cables may be jumper-type cables and the clamps may be alligator-type clamps. Other types of clamps suitable for use with the present invention include a sliding clamp, a hinged clamp, and a wrap-around strap-type clamp. To limit current in the circuit to acceptable levels, it may be necessary to employ one or more resistive electrodes, or heater blocks, placed in the jaws of one or more of the clamps. Intimate thermal contact is established between the heater blocks and the work-piece such that heat generated in the heater blocks is conducted to the work-piece. Heater blocks of different configuration and/or composition are provided to present a range of resistances. For a particular application, a resistance is selected that will limit current flow to a level that will not damage the work-piece, the transformer and cables or the heater blocks themselves. In an alternative embodiment of the present invention, a conventional current limiter is used instead of resistive electrodes such that the maximum allowable current is consistently maintained through the work-piece.

Title: Mail piece weight quality control system and method
Inventor: METELITS STANLEY E
IPC: G07B17/00
Filed: 1990-12-28
Abstract: This invention relates to a system for certifying the accuracy of postage payments based on the weights of mail pieces. The expected weight of each mail piece is determined and a mail processing unit receives data relative to the contents to be inserted into an envelope that together form the mail pieces. A high speed weighing scale is located downstream from the mail processing unit to receive the mail pieces after the mail processing unit has inserted selected materials into envelopes. A comparison is made between the expected weight of each mail piece and its measured weight. If the measured weight of a mail piece is found different than the actual weight beyond certain tolerances, it could be rejected. If a large number of mail pieces exhibit a divergence between the estimated weight and the actual weight, the mail processing unit will be disabled and an examination made to determine what caused the discrepancies in the weights. If there is correlation between the anticipated weights and the measured weights, the mail pieces are placed in trays or other suitable containers to be delivered to the Post Office. A history of mail runs and their accuracy with regard to weight is maintained for record purposes.

Title: Circuit and method for monitoring voltage pulse widths
Inventor: BEG MIRZA A
IPC: G01R29/027
Filed: 1991-05-02
Abstract: 55,771 ABSTRACT OF THE DISCLOSURE         The widths  of pulses in an incoming pulse train are monitored by successively  measuring  the  duration of the pulses in the pulse train and enabling a timing device when the duration of any of  the  pulses  is  more  than a preselected  magnitude. The  timing device is reset and restarted when  the  duration  of  any  of  the  pulses is greater than the preselected magnitude.  An output signal, indicative of an acceptable  condition,  is  produced when the timing  device indicates the expiration of a predeter-mined time delay.  An output signal, indicative  of a non-acceptable condition,  is produced  when the duration of a pulse in the incoming pulse train  exceeds the preselected magnitude.    This  invention  encompasses  both the pulse width monitoring method and  circuits  which  perform this method.

Abstract: An oscillator operational in the millimeter wave and microwave range, including frequencies greater than ?0 GHz, is provided with reduced phase noise by enhancing Q of the resonant circuitry by reactively terminating fundamental frequency oscillation and in-creasing stored fundamental frequency energy in the resonant circuitry. A two frequency system is provided with constructive reflection of energy at fundamental frequency back to the resonant circuitry, and with isola-tion of fundamental frequency energy from the output load. Energy to the output load is obtained from the in-situ generated second harmonic of the active element. Phase noise is reduced by enhancing Q by more than an order of magnitude.

Patent CA-2046153-A1 (CA)
Inventor: ERHARDT ROBERT A
IPC: H05B41/28
Filed: 1991-07-03
Abstract: ABSTRACT OF THE DISCLOSURE          An improved power supply for one or more electric discharge lamps includes a high frequency oscillator-inverter circuit coupled to the output of a full-wave rectifier circuit via a transformer primary winding (25).  The rectifier circuit is energized from a low frequency source of AC voltage.  The oscillator-inverter circuit supplies high frequency oscillations to the lamp via a frequency-dependent ballast coupling circuit.  A regenerative power supply is coupled to the transformer primary winding by means of a secondary winding (62) of the transformer thereby to charge a capacitor (49) operative as a switchable auxiliary supply voltage for the oscillator-inverter circuit.  Improved start-up operation is achieved by winding the transformer (25, 62) so as to provide a polarity inversion for the supply of electric energy to the regenerative power supply.

Inventor: TONG HUA-SOU
IPC: H01J9/14
Filed: 1990-02-28
Abstract: The power handling capacity of nickel-iron-based flat tensioned foil shadow masks for flat faceplate cathode ray tubes (CRTs) is enhanced by providing the flat tensioned mask (FTM) with a thin surface layer which is enriched in nickel, which is converted to a nickel phosphide compound. nickel phosphide surface layer is formed on the mask by immersing the mask in a first bath of a strong reducing acid followed by immersing the mask in a second strong reducing acid having an effective amount of hypophosphite ion. The thin surface layer of a nickel phosphide compound increases the FTM emissivity and reduces FTM doming at high electron beam energies. The nickel phosphide compound may be stabilized in the frit-lehr cycle during CRT assembly or in a separate heating operation.
