Patent EP-0349477-A3 (EP)
Title: Solid state overvoltage protection circuit
IPC: H04M3/18
Filed: 1989-06-21
Abstract: An overvoltage protection circuit (16) for electronic equipment, such as telecommunications equipment (10), computers and instrumentation equipment, having tip and ring lines (TR) includes a first voltage sensitive switch (30) having first and second terminals. The first terminal of the first switch is connected to the tip line (T). A second voltage sensitive switch (32) includes first and second terminals. The first terminal thereof is connected to the second terminal of the first voltage sensitive switch (30), and the second terminal thereof is connected to the ring line (R). A third voltage sensitive switch (34) includes first and second terminals. The first terminal is connected to the second terminal of the first voltage sensitive switch and to the first terminal of the second voltage sensitive switch. The second terminal of the third voltage sensitive switch is connected to ground potential. The switches are conductive when a respective voltage threshold is exceeded. In one embodiment, the sum of the voltage thresholds of the first and third voltage sensitive switches is approximately equal to the sum of the voltage thresholds of the second and third voltage sensitive switches, such that the circuit is conductive when either of the thresholds of the first and third voltage sensitive switches or the second and third voltage sensitive switches are exceeded. In another embodiment, the holding current of the third voltage sensitive switch is lower than that of either the first or second switch. In this combination, the third switch turns on first, then both the first and second switches turn on in unison and hold the lines in balance during switching.

Title: Recording and reproducing apparatus for optical disk
IPC: G11B7/125
Filed: 1990-03-02
Abstract: The present invention relates to an optical 
recording and reproducing apparatus comprising an 
erroneous recording prevention means which prevents this 
apparatus from making an erroneous recording or erasing 
operation while it records data on a writable disk (1). The 
apparatus is arranged such that, while it is performing 
a recording or erasing operation, a state of its beam of 
light just about to go off the control point of tracking 
and a state of its beam of light just about to go off 
the control point of focusing are each monitored and, 
when either of the states is detected, the recording or 
erasing operation is canceled. Hence, laser power of 
the beam of light can be controlled before the beam of 
light completely goes off the control point of tracking, 
thereby preventing the beam of light from affecting data 
having been recorded along other tracks.

Title: Method of manufacturing non-volatile semiconductor memory device
IPC: H01L29/792
Filed: 1991-03-20
Abstract: Arsenic ions are implanted into an element region of a 
silicon substrate (31) so as to form a first impurity region 
(35). Then, an insulating film (36) is formed on the 
silicon substrate in the element region, followed by 
forming a heat resistant film (41) on the entire surface 
of the silicon substrate. Further, a resist film (37) 
is formed on the silicon substrate, followed by 
patterning the resist film to form an opening on at 
least the first impurity region. After the patterning 
step, the heat resistant film positioned below the 
opening of the resist film is removed, followed by 
implanting phosphorus ions into the substrate using the 
patterned resist film as a mask so as to form a second 
impurity region (38). In the next step, the resist film 
is removed and, then, annealing is applied with the heat 
resistant film used as a mask. After the annealing 
step, the resist film is removed, and an annealing is 
performed with the heat resistant film used as a mask, 
followed by removing the insulating film using the heat 
resistant film as a mask. Finally, a tunnel oxide film 
(39) is formed on that portion of the silicon substrate, 
followed by forming an electrode (40) on the tunnel 
oxide film so as to manufacture a desired nonvolatile 
semiconductor memory device.

Patent EP-0665457-A3 (EP)
IPC: D03D13/00
Filed: 1995-02-01
Abstract: A woven structure is described in which optical 
fibers (12A,12B) are positioned and held in the structure in a manner 
to maximize their optical efficiency. The structure 
consists of non-optical fibers (10A,10B;11A,11B) extending in both the warp 
and woof direction, the optical fibers (12A,12B) are positioned in 
channels between supporting fibers in the warp direction. 
Selected ones of the non-optical fibers in the warp 
direction may be electrical conductors. The structure is 
manufactured using conventional weaving equipment by 
positioning both the optical fibers and the non-optical warp 
fibers, and then weaving the woof fibers into place without 
causing micro-bends or discontinuities in the optical 
fibers. The structure is woven with the optical fibers 
positioned in zero warp. The woven grid-like mat can be 
coated with a protective material that either enables it to 
form a flexible sheet or a rigid, hard, grid-like mat which 
has aligned zero warp optical fibers embedded therein. The 
structure shown can be used to provide sensing, imaging or 
communications. It can be utilized for optical backplanes 
for opto-electronic systems or a housing for opto-electronic 
components. Several types of interconnects or connectors 
can be fabricated according to the present invention capable 
of interfacing with the woven structure in an array-based, 
optical or opto-electronic, active or passive 
interconnect/connector scenario. The invention may also be 
used in highly parallel, high performance computer systems 
and sensing systems.

Abstract: A display controller to upscale a source video image for display on a display unit
of a computer system. An encoder circuit stores in a local memory pixel data of previous
scan lines required for interpolation in a compressed format using differential pulse code
modulation (DPCM) scheme. As a part of the DPCM scheme, encoder generates a
predicted value for each source video pixel data as a function of at least one prior pixel
data value in the scan line. However, when a slope over load condition is encountered,
the decoder circuit changes the predicted value for a subsequent pixel data value to a
different value, which may enable the graphics controller circuit to avoid a slope overload
condition as to subsequent pixel data values. A decoder circuit decompresses the pixel
data into original format prior to sending to an interpolator. The interpolator receives a
present scan line and the decompressed data of previous scan lines, and interpolates the
received pixels to generate additional pixels required for upscaling the source video
image. When a slope overload condition is encountered, a override circuitry causes the
interpolator to use for interpolation a pixel data value in the present scan line in stead of
the pixel data value causing the slope overload condition.
