Abstract: A magnetic disk drive channel circuitry is shown and 
described that generates eight incremental values of write 
current and eight incremental values of delta-V (the minimum 
voltage change per unit time which tests signals to 
discriminate between data and noise). Each of these variable 
parameter values may be program selected by a three bit bus 
signal. This variability testing of and adaptation to the 
optimum parameter value for each head media combination and 
by grouping tracks in contiguous data bands, the parameters 
may be optimized for tracks near the inner diameter, the 
outer diameter and in the middle band. The variable delta-V 
can also be used as an additional data recovery tool wherein 
re-reading with a lower value enhances recovery of missing 
bit errors and re-reading with an increased value can assist 
recovery from an extra bit error.

IPC: G06T15/30
Filed: 1987-04-10
Abstract: A video picking and clipping method and apparatus are 
described. The picking method and apparatus comprise: A 
CPU and a direct memory access (DMA) circuit which is used 
with a graphics microprocessor (GµP) for virtually redrawing 
a display list from a system memory of objects in a bit map. 
A starting address and a number corresponding to the 
number of instructions in a segment comprising a plurality of 
display lists are sent to the DMA for this purpose. When the 
coordinates of a pointer match the coordinates of a selected 
data object, a pick interrupt signal and special pick instruc­
tion is sent to the CPU. The CPU then uses the starting 
address of the display list of a selected object from a table to 
generate a new display list to perform a pre-selected 
operation on the selected data project. The clipping method 
and apparatus comprise a plurality of data planes for storing 
data objects, a match plane for storing a clipping object and a 
one-bit register. In use, the pixels in the data and match 
planes are scanned. When a match occurs between a pixel in 
the match plane and the contents of the one-bit register, a 
match signal is generated. The match signal enables the data 
planes to re-store the corresponding pixels of the data 
objects in the match planes.

Title: Apparatus and method for continuous manufacture of armoured optical fiber cable
IPC: B23K26/20
Filed: 1987-08-25
Abstract: An apparatus and method for continuously manufacturing optical fiber cable in which optical fiber is encased by an hermetically sealed homogeneous metal tube formed from flat metal strip (11). A first assembly of mating rollers (26, 28) having successively different shapes forms the flat metal strip into a partially formed tube (12) having a longitudinal gap. Optical fiber (13) is guided through the gap to lie within the partially formed tube. The tube (12) is then closed by a second assembly of mating rollers having successively different shapes. A laser beam is used to weld the seam closed without filler metal and without heat shielding between the seam and the optical fiber. The finished tubing with optical fiber therein is sunk by being drawn through wire dies to reduce the diameter. A wheel draws the tubing through the apparatus at constant speed to effect a uniform weld line. In another embodiment, an introducer tube of smaller diameter than the hermetically sealed homogeneous metal tube extends within the metal tube to about the point of tangential approach of the metal tube to the wheel. Gas flows through the introducer tube to carry the optical fiber by viscous drag and blow the optical fiber against the outer circumference of the metal tube as the metal tube wraps around the wheel.

on the basis of an ordered search sequence of all combina­
tions, and certain steps of the sequence and corresponding 
combinations are omitted from the sequence if they involve 
subcombinations previously searched and found to be at or 
above the target weight. The scales produce signals rep­
resentative of the product weight, and the signals are 
calibrated and processed to eliminate measurement errors.

Abstract: A television picture magnification system which 
provides real-time magnified video images includes a memory 
system (16,18,20,22,26) which stores L horizontal line 
intervals of samples representing one field of the 
unmagnified video image during a first time interval and 
which provide K of those L lines of samples during a second 
time interval offset from the first time interval by less 
than one field period. The K lines of samples provided by 
the memory are interpolated by the system to develop L 
lines of samples which represent one field of the magnified 
image. The offset delay between the first and second time 
intervals ensures that any field of the magnified image 
includes samples from only one field of the unmagnified 
image.

Title: A method and apparatus for controlling a manipulator
IPC: G05B19/4155
Filed: 1989-03-17
Abstract: A three-dimensional vision seam tracking method 
and apparatus for controlling the motion of the center 
point of a tool mounted on a manipulator. The 
manipulator is provided with a control to operate the 
manipulator members to move the tool center point at 
programmed velocities along a programmed path 
corresponding to the seam. The manipulator is provided 
with a vision system including a laser scanner/camera 
head mounted ahead of the function element. The 
control is programmed with dynamically varying 
orientation angles to control the orientation of the 
tool during seam tracking. The laser scanner/camera 
head scans the seam at predetermined time intervals. A 
set of coordinates for the center point of the seam in 
a coordinate system relative to the camera is provided 
for each scan. The sets of camera coordinates are 
transformed to the coordinate system of the manipulator 
using transformation matrices employing the orienation 
angles in effect at the time of the scan for the set of 
camera coordinates being transformed. The transformed 
coordinates are stored in a FIFO buffer until needed. 
The seam tracking routine of the manipulator control 
removes FIFO entries at some later time and alters the 
manipulator's programmed path to move the tool center 
point along the seam.

Title: Method of producing a semiconductor device having shallow highly doped regions
IPC: H01L29/78
Filed: 1989-08-23
Abstract: A method for fabricating a semiconductor device, such as 
a silicon MOS FET, having diffusion regions with a 
reduced depth and high dopant concentration, is 
disclosed. Beneath the surface of the relevant semi­
conductor substrate, an amorphous layer is formed cor­
responding to the diffusion regions in advance, 
following which a doped polysilicon layer is formed. 
Thereafter, the polysilicon layer is doped employing a 
dopant ion implantation such that the peak point of the 
dopant concentration distribution is located substan­
tially near the interface between the silicon substrate 
and the polysilicon layer. Subsequently, the substrate 
is subject to a rapid thermal annealing for diffusing 
the dopant from the doped polysilicon layer, recrystal­
lizing the amorphous layer portion, and activating the 
dopant contained in the recrystallized layer portion to 
be the diffusion regions. A silicide layer is used in 
the place of the polysilicon layer to have a high elec­
trical conductance.

Title: Leak detector
IPC: G01M3/26
Filed: 1989-06-13
Abstract: A leak detection system and a method of detecting 
leaks are disclosed for detecting a leak in a system, 
including a pump, a dispenser, a conduit communicating the 
pump and the dispenser, and a valve in the conduit. The 
valve includes an electronic flow measurement device for 
detecting leaks in the system downstream of the device.  
     The system may be operated by a control circuitry, 
which indicates a predetermined flow of fluid indicating a 
leak. The present invention is also directed to a method 
of detecting a leak in a system having a fluid pump, a 
dispenser, a conduit connecting the pump and the 
dispenser, a valve in the conduit, and an electronic flow 
detection system in the valve. The valve is provided with 
an orifice communicating the conduit with the electronic 
flow detection system.  
     The method includes the steps of activating the pump 
and opening the dispenser to dispense a fluid, and then 
closing the dispenser while continuing the activation of 
the pump thereby increasing fluid pressure in the 
conduit. The increase in fluid pressure causes the valve 
to close, thus isolating the pump from the dispenser 
except for the orifice in the valve. The electronic fluid 
detection system senses the flow of fluid through the 
orifice.
