Title: Soldering device for soldering components onto printed circuit boards
IPC: B23K3/047
Filed: 1990-09-17
Abstract: In a soldering device with two or four stirrup electrodes (B1, B2) and a suction pipette (S) arranged centrally between the stirrup electrodes (B1, B2) for picking up, transporting and setting down the components (BE) on the allocated soldering points, the suction pipette (S), at least in its opening area, is made of an elastically deformable material, such as, for example, hard rubber. The suction pipette (S) preferably carries a pipette insert (PE) made of this elastically deformable material. Due to this elastically deformable material, the suction pipette (S) can then be used for pressing the components (BE) onto the soldering point even if the components (BE) are in a sloping position on the printed circuit board (LP). Loading of the connecting legs (A) of the oblique component (BE) in particular on one side is then at least largely avoided. <IMAGE>

processes into useful, process-related information. 
The passive acoustics 
system comprises a sensor for transforming vibratory 
energy of a container containing a fluidized bed into 
electrical energy, an amplifier, a data collector for 
converting electrical signals from the amplifier from a 
function of time to a function of frequency, a computer, 
and means to transfer electrical signals from the data 
collector to the computer wherein the signals are 
algorithmically converted to process-related informa­
tion.

Title: A method for gravel packing a well
IPC: E21B43/04
Filed: 1990-08-13
Abstract: A method for gravel packing a well penetrating an unconsolidated or poorly consolidated subterranean oil or gas reservoir. The well can employ a borehole casing with perforation tunnels for fluid communication between the borehole casing and a substantial portion of the reservoir. A sand screen is located inside the well casing and in juxtaposition with the perforation tunnels forming an annulus between the borehole casing and the sand screen. One or more conduits are positioned in juxtaposition with the sand screen with openings to provide fluid communication between the conduit and a substantial portion of the annulus between the borehole casing and the sand screen. A slurry of gravel is injected down through the annulus between the borehole casing and the sand screen until the annulus being packed thereby plugging the annulus between the casing and the sand screen, the slurry of gravel will continue to flow down the conduit and into the annulus below the gravel bridge thereby completely packing the annulus between the sand screen and the borehole casing. The oil or gas in the reservoir is then produced through the gravel packed borehole casing and the sand screen. If desired, the slurry of gravel may be injected down the well and up the conduit and annulus to accomplish complete packing. The method is also applicable to placing gravel packs in an open-hole wellbore adjacent to a substantial portion of an unconsolidated or poorly consolidated subterranean oil or gas reservoir.

Abstract: A test circuit for boundary scan testing of analog signals provides for known upper and lower bound values at specified times for testing whether sample analog signals are within the specified lower and upper bound values. If the sample analog signals are not between the known upper and lower bound values, the boundary scan analog signal test circuit produces a result flag indicating a "not pass" for the device being tested. If the sample analog signal being tested is found to be within the known upper and lower bound values, then the circuit generates a result flag indicating that the device being tested has passed the test. <IMAGE>

abnormal state, regardless of fluctuations in a power source
voltage. The fetching of drive voltages of N (e.g., N=6) solenoids in
order is carried out M (e.g., M=2) times. A maximum value of
minimum values of the drive voltages of the solenoids, among the
drive voltages fetched M times for each solenoid, is computed and
set as a reference voltage V REF  for abnormality judgment.
Maximum values of the drive voltages of the solenoids are
computed and set as drive voltages V SOLX  of the solenoids to be
used for abnormality judgment. It is judged whether each of the
solenoids is in an abnormal state, on the basis of the reference
voltage V REF  and the drive voltage V SOLX  of each solenoid.
