Title: Reticle Having a Number of Subfields
Inventor: DAVIS DONALD E
IPC: H01J37/317
Filed: 1994-09-08
Abstract: A reticle for an electron beam system for direct writing applications has a base layer that contains a reticle pattern; a set of reinforcing struts connected to the base layer separating  the  base  layer  into  a  set  of  non-contiguous subfields;  in which the pattern is carried by a set of apertures areas in said base layer; and in which the set of non-contiguous subfields has overlapping rim portions in which the overlap portions of corresponding lines have a pattern that produces the correct exposure when the subfields are correctly   aligned   and   minimizes   pattern   feature discontinuities  when  the  subfields  are  misaligned.    A corresponding method consists of overlapping the reticle at the field or subfield boundaries and forming a spatial breakup or a partially transmissive area of the pattern elements contained in the overlapped areas,  preventing shorts and open failures in the  lines or pattern elements  and providing additional tolerance for the alignment of the adjacent fields or subfields.

Patent CA-2145571-A1 (CA)
Inventor: SESHADRI NAMBIRAJAN
IPC: G10L21/0208
Filed: 1995-03-27
Abstract: The recovery of each signal in a transmitted signal including a pair of superimposed signals is improved by the use of linear prediction. The pair of signals includes various combinations of analog and digital signals, e.g., an analog signal sample superimposed upon a digital signal sample, or a digital signal sample superimposed upon another digital signal sample. In a first embodiment, prediction coefficients for the analog signal are generated from the received signal. These coefficients are then used to recover the analog and digital signals from the received signal. In a second embodiment, the analog signal recovered, pursuant to the first embodiment, is considered a tentative estimate of the analog signal, and prediction coefficients for this tentative analog signal estimate are formed and used to generate final estimates of the analog and digital signals. In still other disclosed embodiments, prediction coefficients are transmitted to the reciver, and the analog signal superimposed  upon the digital signal is a residual analog signal for which prediction coefficients are generated without regard to the transmitted prediction coefficients. These prediction coefficients are then used to recover the digital signal and the residual analog signal. The residual analog signal is then processed using the transmitted prediction coefficients to recover the analog signal. Further embodiments disclose several techniques for generating prediction coefficients for the analog signal.

Title: Electrical connection of printed circuit board to line leads on brushless parmanent magnet refrigeration motors
Inventor: BAKER GERALD N
IPC: H02K11/00
Filed: 1995-05-03
Abstract: A brushless permanent magnet (BPM) motor has a stator mounted on a hub projecting from a base-enclosure.  The base-enclosure is cup-shaped, open at an end remote from the stator hub, having a side wall and a top wall defining an interior space.  A printed circuit board (PCB) is mounted above the top wall, below the stator.  Electrical conductors electrically connected to a printed circuit on the printed circuit board extend through the top wall and into the interior space.  The electrical conductors are mounted in a connector of the insulation displacement type, one form of which is known commercially as a Magmate connector.  In the preferred embodiments, such a connector is made integral with an interior surface of the base-enclosure.  It comprises an elongate boss with longitudinal slots in it to receive electrical conductors that are inserted into the slots and bent to extend transversely to a long axis of the boss, and channels extending parallel to the long axis of the boss to receive other electrical conductors, usually in the form of spade terminals or the like, which fit tightly in the channels and make solid physical and electrical contact with the transversely oriented conductors.  When current is supplied directly to the only PCB, current supply conductors extend through a side wall port and are electrically connected in the connector boss to the electrical conductors from the printed circuit.  When current is supplied to a second PCB, housed in the base-enclosure, conductors from the second PCB are electrically connected in the connector boss to the conductors from the PCB mounted above the top wall of the base-enclosure.        In either embodiment, conductors from a printed circuit board are held spaced apart by one or more passive elements of the circuit, such, for example, as a capacitor, a resistor, or a diode, in substantial parallelism a distance equal to the distance apart of the slots in the connector boss.  This serves the double purpose of connecting the element into the circuit, and facilitating the assembly of the motor.
