Title: Synchronizer for establishing synchronization between data and clock signals

Granted: 1992-05-19
Abstract: "SYNCHRONIZER FOR ESTABLISHING SYNCHRONIZATION        BETWEEN DATA AND CLOCK SIGNALS"     ABSTRACT OF THE DISCLOSURE A frame synchronizer comprises a frame sync detector for detecting a frame sync pattern multiplexed with a data signal. First and second counters are incremented in response to an input clock signal to generate output signals at frame intervals. A mismatch detector detects a first mismatch between the output of sync detector and the output of first counter and a second mismatch between the sync detector output and the output of second counter. To reduce resynchronization period, the second counter is disabled in response to the detection of the second mismatch and its binary count is loaded into the first counter upon detection of the first mismatch. According to a different aspect, a bit synchronizer includes a plurality of latches connected to a data input terminal for respectively latching a data signal in response to a latch timing signal applied thereto. A mismatch detector is provided for detecting a mismatch between outputs of the latches. The detection of the mismatch indicates that data and clock inputs has lost bit synchronization and the latch timing pulse is approaching a data transition. Clock input is normally applied from an input terminal to the latches as the latch timing signal. Upon detection of a mismatch, the phase, or logic level of the latch timing signal is reversed to shift its timing to a point where the data signal has a steady logic level.

Green ABSTRACT OF THE DISCLOSURE         A  process  is  described  for  manufacturing  an improved lift truck fork.  In the improved lift truck fork, the curved portion of the  fork,  known as  the  "heel"  is modified to reduce the stresses which arise in this area when  the  fork  is  loaded.    The  modifications  include thickening of the heel during forming by approximately 5% toward the blade and approximately 2.5% toward the shank, enlarging the inside radius of the heel by machining and providing a clearance cavity  in  the  top  surface of  the region where the blade meets the heel.   The process for manufacturing  lift  truck  forks  comprises  the  steps  of bending,  then  upset  using  a  backing  die  of  proper configuration to form a thickened portion of the heel which tapers into the lower portion of the blade,  followed by restriking with a die suitably shaped to form an appropriate inside  radius  and clearance  cavity  in  the  heel,  heat treatment and final machining to remove surface anomalies and give the desired configuration to the inside radius.

Abstract: ABSTRACT      An apparatus for inspecting an SMT printed circuit board includes an inspection head mounted to an X-Y table, for directed movement above the SMT printed circuit board which is to be inspected. The inspection head is caused to proceed to successive viewing fields along the surface of the SMT printed circuit board, for inspection by a series of cameras disposed within the inspection head together with appropriate lighting which is selected according to the inspection which is to be performed.  Prior to soldering, it is determined whether each of the series of components to be placed on the printed circuit board were deposited as scheduled, and whether the deposited components were correctly positioned.          Following the soldering procedure, it is again determined whether each component remains present on the board, and in its correct position, and steps are taken to inspect the solder fillets, and to inspect for any solder bridges.

Abstract: ABSTRACT         A novel method of geophysical exploration is described for obtaining estimates of formation lithology from measures of formation anisotropy.  First and second measures of formation anisotropy can be transformed into estimates of formation lithology by crossplotting them onto a lithology diagram.  In one embodiment of the pres-ent invention, the lithology diagram comprises two sepa-rate axes representing measures of formation azimuthal anisotropy and transverse isotropy for a selected forma-tion property which defines regions of separate litholo-gies.  The lithology diagram can provide a novel means for discriminating formation lithology from the measures of formation anisotropy.

Title: Fuel supply system with pneumatic amplifier
Inventor: STAERZL RICHARD E
IPC: F02M69/08
Filed: 1989-09-28
Granted: 1994-04-12
Abstract: ABSTRACT OF THE DISCLOSURE      A fuel control system for an internal combustion engine includes means for pneumatically amplifying sensed air flow pressure differential (PD) through an air intake venturi between a first combustion air pressure sensor outside the venturi, and a second combustion air pressure sensor in the venturi.  Pressure at the inner end of the second pressure sensor is reduced by altering the air flow path to create a vacuum at the inner end of the second pressure sensor relative to the remaining air flow  through the venturi.  A throttle plate in the venturi has a by-pass hole therethrough directing air flow along a given direction past the inner end of the sensor and through the by-pass hole when the throttle plate is in the idle position.  The given direction of air flow past the inner end of the sensor prevents air flow into the inner end of the sensor tube to prevent an increase of sensed pressure thereat, and instead creates a vacuum to pull air out of the inner end of the sensor tube, to reduce pressure thereat.  The system maintains a sufficient sensed pressure differential (PD) between the sensed pressure outside of the venturi and the sensed pressure in the venturi, including at idle, and also amplifies sensed pressure differential to provide improved tracking of fuel flow requirements between prescribed lean limit (LL, FIGS. 20-22) and rich limit (RL) requirements, including at idle and low speed.
