Title: Droplet volume modulation techniques for ink jet printheads
Inventor: WALLACE DAVID B
IPC: B41J2/14
Filed: 1994-05-03
Abstract: An ink jet printhead and an associated method for operatively driving the ink jet printhead to cause the ejection of a volume modulatable droplet from an ink-carrying channel  thereof partially defined by a piezoelectric sidewall actuator.  The voltage applied across the sidewall actuator is raised from a rest voltage to a first voltage to deflect the sidewall actuator from a rest position to a first position and maintained at the first voltage for a first period of time.  The voltage applied  across  the  sidewall  actuator  is  then dropped to a second voltage, lower than the rest voltage, to deflect the sidewall actuator from the first position, past the rest position, to a second position and maintained at the second voltage for a second period of time.   The voltage applied across the sidewall actuator is then returned to the rest voltage to deflect the sidewall actuator back to the rest position.  The first and second time periods are selected, relative to each other, to select a droplet volume for ink ejected from the ink-carrying channel.  The voltage applied across the sidewall actuator is then returned to the rest voltage, thereby causing the ejection of a droplet of ink having the selected droplet volume.

Abstract: A garage for storing vehicles of a continuous cable railway system.  The garage has a plurality of side  tracks  arranged  parallel  or  substantially parallel  to  one  another to  form  preferably  a rectangular shape.  The garage is loaded with vehicles from the station track of the cable railway system over a first feeder track.  A second feeder track is used to load the vehicles from the garage to the station track.   Conveying units are present at the feeder tracks and side tracks to convey the vehicles. A single junction having two switch units is arranged between the feeder tracks.  The junction also allows the vehicles to travel from one of the feeder tracks to the other.  Sliding switches, each having an arc-shaped conveyer track, are located on the incoming and outgoing sides of the side tracks.   Buffer tracks, each having several stopping points, act as buffers in the feeder tracks for the vehicles when loading or unloading the garage.

Patent CA-2181130-A1 (CA)
Inventor: CLARK STANLEY R
IPC: F16C33/72
Filed: 1996-07-12
Abstract: A stationary, formed metal cap covers the bearing assembly of the rotatable firming wheel to protect the bearings against the ingress of mud, residue and moisture. A smooth, convex, exposed outer surface on the cap discourages the accumulation of residue and mud between the rotating wheel and its stationary support arm so as to keep the wheel freely rotating during its rolling movement in the seed trench. A flat, band-like, circular edge around the periphery of the convex surface is received within a circular groove on the face of the wheel to obstruct the ingress of moisture and materials at that location and disposes the marginal periphery of the convex surface in a substantially flush condition with the surface of the wheel to prevent wrapping and accumulation of trash.

Inventor: WANG YI-MIN
IPC: G06F11/14
Filed: 1996-09-09
Abstract: Disclosed is a method for error recovery in a multiprocessing computer system of the type in which each of the processes periodically takes checkpoints. In the event of a failure. a process can be rolled back to a prior checkpoint, and execution can continue from the checkpointed state. A monitor process monitors the execution of the processes. Upon the occurrence of a failure, a target set of checkpoints is identified, and the maximum consistent global checkpoint, which includes the target set of checkpoints, is computed.  Each of the processes is rolled back to an associated checkpoint in the consistent global checkpoint. Upon a subsequent occurrence of the same failure, a second set of checkpoints is identified, and the minimum consistent global checkpoint, which includes the target set of checkpoints, is computed. Each of the processes is rolled back to an associated checkpoint in the consistent global checkpoint.  Upon another occurrence of the same failure, the system is rolled back further to a coordinated checkpoint. Also disclosed are novel methods for calculating the minimum and maximum consistent global checkpoints.  In accordance with one embodiment, the minimum and maximum consistent global checkpoints are calculated by a central process.  In accordance with another embodiment, the minimum and maximum consistent global checkpoints are calculated in a distributed fashion by each of the individual processes.

Inventor: THURSTON MARLIN O
IPC: G01T1/161
Filed: 1996-10-11
Abstract: An method  for  identifying  a  sentinel  lymph  node associated, for example, with melanomas or breast tumor wherein a radiopharmaceutical is injected at the side of the neoplastic tissue and is permitted to migrate along alymph duct to collect at a sentinel node.  The method involves locating a peak rate of photon emissions by providing a photon emissions probe with a detector, the probe being capable of receiving varying rates of emissions and providing output  signals.   A control  system receives the output signals and forms an output representative of a photon count rate above a threshold value derived in conjunction with a base value and is actuable to increase the threshold count value.   The photon emission rate of a first location having a radiopharmaceutical is measured.   A second location is also measured and a determination is made between which location has an emissions rate sufficient to actuate the control system to elevate thresholds.
