Title: Universal surface finish for DCA SMT, and pad on pad interconnections
Inventor: GOODMAN DALE ERNEST
IPC: H05K3/24
Filed: 1998-04-29
Abstract: A printed circuit connector terminal pad coating technique is
disclosed which functions as a single universal pad surface which
supports multiple electrical connection practices including wirebonding,
soldering, and wear resistant, pad on pad mechanical connection. The
tri-plate surface treatment includes an initial diffusion resistant
coating of nickel; an intermediate layer of hard, wear resistant noble or
semi-noble metal that provides pad on pad connector reliability and
affords a metallurgically stable solder joints and wirebond interfaces;
and a final coating of soft gold. The intermediate layer may be pure
palladium having a nominal thickness of 35 microinches or a layer of
gold, hardened by cobalt, nickel, iron or a combination of these dopants
to effect a hardness of 200 to 250 (Knoop scale) . The use of a common
surface treatment for the multiple attachment processes is implemented
with a single masking step, rather than a sequence of selective masking,
plating and stripping operations. In the printed circuit environment, the
masking is provided by the final covering that encloses, seals, and
electrically insulates the conductors in a circuit board application or
in the instance of a flexcable, the adhesive coated flexible coverlay the
covers and seals the copper conductor elements while exposing the
conductor terminal pads.

Abstract: First and second magnetic heads provided on a rotary drum
alternately scan a magnetic tape. The first and second magnetic
heads are different from each other in azimuth angle. A digital
information signal is fed to the first magnetic head and is recorded
on the magnetic tape via the first magnetic head while the first
magnetic head is scanning the magnetic tape in a long time
recording mode of operation where the magnetic tape is driven at a
speed equal to a predetermined standard speed multiplied by 1/N.
Here, N denotes a predetermined integer equal to or greater than 2.
The digital information signal is fed to the second magnetic head
and is recorded on the magnetic tape via the second magnetic head
while the second magnetic head is scanning the magnetic tape in
the long time recording mode of operation. In the long time
recording mode of operation, the feed of the digital information
signal to the first magnetic head and the second magnetic head is
inhibited during an (N-1)/2 turn of the rotary drum after either the
feed of the digital information signal to the first magnetic head or
the feed of the digital information signal to the second magnetic
head. A control pulse signal is recorded on the magnetic tape via a
third magnetic head which is fixed. The control pulse signal has a
period corresponding to one turn of the rotary drum. The control
pulse signal has a duty cycle depending on timings at which the first
and second magnetic heads record the digital information signal on
the magnetic tape.

hydrogen, C 1 , C 2 , C 3 , C 4 , C 5  alkyl, any of which are linear
or branched, cyanoalkyl, cyclohexyl, methyl cyclohexyl,
phenyl, benzyl, and halogenated or oxygenated derivatives
thereof. 
     In accordance with the invention there is further provided
a method of synthesizing 1-halo-1-iodoethane by reacting
hydrogen iodide with vinyl chloride or vinyl fluoride in
the presence of an iodine generating catalyst under certain
specified conditions. The resulting product of the

free radical methods at higher temperatures and/or with the
use of conventional chain transfer agents for vinyl halide
polymer.

Abstract: A low power ECP trainline (23) communication method is provided wherein power
consumption by each freight car's on-board ECP transceiver (14) is minimized such that it can be

identifying a wake-up message from the MC can include using the signal strength of the message
and making the wake-up command sensitive to the ECP trainline power status. In the latter case,
detection of zero trainline power is a signals to wake-up the ECP transceiver.

Patent EP-0937987-A2 (EP)
Title: Sparse vector rasterization
Inventor: SULLIVAN STEVEN K
IPC: G09G5/37
Filed: 1999-02-09
Abstract: A method for rasterization of a set of voltage-versus-time data-address pairs
into horizintal and vertical locations of a multi-bit raster display memory of a digital
oscilloscope or similar electronic data acquisition instrument is disclosed. It provides a
new way of controlling digital intensity, by allowing the operator and/or a function
based on the instrument's trigger rate to set the number of intensity units available for
brightening the pixels affected by the rastorization of each acquisition data pair. If a
vector has more pixels than there are units of intensity available, the number of pixels
that are to be brightened is limited but spread out over the vector's length by an
algorithm that includes at least some degree of randomization. If there are more units
of intensity available than there are pixels to put them in, the extra ones can either be
distributed into each pixel or randomly added along the vector or ignored. If the
vector has no length, all of the available intensity, or some lesser amount of intensity, is
put on one pixel. Setting a small minimum vector length, below which only limited
vector fill is used, can save time by limiting the amount spent on insignificant details.
Setting maximum and minimum intensity levels for those pixels that are affected by the
rasterization process can limit saturation and assure that areas that receive only one or
a few attacks will still have an intensity level that is perceptible. Sparse vector
rasterization avoids the hard binary choice between using a dot mode or a vector
mode, and gives the user an analog-like intensity control that produces a perceived
continuum of viewing choices. It does this while maximizing the number of pixels
updated within the context of how many waveforms are being acquired and need to be
processed.
