Title: Monolithic semiconductor device having ccd, bipolar and mos structures
IPC: H01L21/339
Filed: 1990-05-22
Abstract: A semiconductor device comprising a semiconductor 
chip (1, 4) formed of a substrate (1) of a first conduc­
tivity type (P) and an epitaxial layer (4) of the first 
conductivity type (P) formed on the substrate (1), a 
charge transfer device section (200) formed in the epi­
taxial layer (4) and driven by a given clock, and a pre­
set region (3-1, 5-1, 6-1) of a second conductivity type 
(N) formed adjacent to the charge transfer device sec­
tion (200) in the semiconductor ship (1, 4). The preset 
region (3-1, 5-1, 6-1) includes a first layer (3-1) of 
the second conductivity type (N) formed in a boundary 
portion between the substrate (1) and the epitaxial 
layer (4), a second layer (5-1) of the second conduc­
tivity type (N) formed on the first layer (3-1) the epi­
taxial layer (4), and a third layer (6-1) of the second 
conductivity type (N) formed on the second layer (5-1) 
in the epitaxial layer (4) to reach the surface of the 
substrate (1). The maximum value of the second conduc­
tivity type impurity concentration of the third layer 
(6-1) is set smaller than the maximum value of the 
second conductivity type impurity concentration of the 
first layer (3-1). A bipolar transistor section (100) 
is formed in the third layer (6-1).

Patent EP-0380240-A3 (EP)
IPC: G06F17/30
Filed: 1990-01-18
Abstract: A data base management system encodes information (such as the field 
values of a database record, or the words of a text document) so that 
the original information may be efficiently searched by a computer. An 
information object is encoded into a small "signature" or codeword. A 
base or "leaf" signature is computed by a known technique such as 
hashing. The logical intersection (AND) of each possible combination 
of pairs of bits of the base signature is computed, and the result is 
stored as one bit of a longer combinatorial signature. The bit-wise 
logical union (bit-OR) of the combinatorial signatures of a group of 
records produces a second-level combinatorial signature representing 
particular field values present among those records. Higher-level 
combinatorial signatures are computed similarly. These combinatorial 
signatures avoid a "saturation" problem which occurs when signatures 
are grouped together, and a "combinatorial error" problem which falsely 
indicates the existence of non-existent records, thereby significantly 
improving the ability to reject data not relevant to a given query. 
When the combinatorial signatures are stored in a hierarchical data 
structure, such as a B- tree index of a database management system, 
they provide means for more efficiently searching database records or 
document text by eliminating large amounts of non-matching data from 
further consideration.

Title: Controlling the combining of video signals
IPC: H04N5/262
Filed: 1990-01-18
Abstract: Apparatus for controlling the combining of video signals 
includes a field rate microprocessor (10) that generates edge data 
defining the edges of a polygonal first picture (KP) which is to be 
keyed into a second picture (B) to produce a composite picture. Two 
line rate microprocessors (16, 18) generate from the edge data, for 
each horizontal scanning line of the composite picture in which a row 
of pixels corresponding to that scanning line is intersected by edges 
of the first picture, signals representing: the horizontal locations 
of first and second start pixels, namely those of the row of pixels in 
which first and second edges (e.g. E1, E2), respectively, of the first 
picture (KP) start to intersect the row; the gradients of the first 
and second edges; and a key value (the proportion of the first picture 
to be contained in a pixel of the composite picture) for each of the 
first and second start pixels. A key value generator (32) generates, 
for each scanning line of the composite picture, a key value for each 
successive one of the row of pixels corresponding thereto, by: ramping 
up the key value from zero, for pixels preceding the first start 
pixel, by incrementing the key value for the first start pixel, for 
pixels following the first start pixel, by an amount per pixel 
determined by the gradient of the first edge (e.g. E1), until the key 
value reaches unity; and ramping down the key value from unity, by 
decrementing the key value for the second start pixel, for pixels 
following the second start pixel, by an amount per pixel determined by 
the gradient of the second edge (e.g. E2), until the key value reaches 
zero.

Title: Seismic pulse generation
IPC: G01V1/137
Filed: 1990-04-05
Abstract: A seismic pulse generator comprises a body 1 having an 
internal gas-pressurizable first chamber 2 adjoining a 
second chamber 6 for containing a fluid. A flap valve 
member 21 is rotatable about a pivot axis for closing a 
bore 24 communicating with the first chamber. A latch 22 
releasably retains the flap valve member in the closed 
position and a gas operated piston 13 slidably moves 
within an associated cylinder 12. When the first chamber 
2 is pressurised with gas and the flap valve member 21 is 
released from its closed position to uncover the bore 24, 
the piston 13 moves to cause communication between the 
chambers 2,6 and generation of a shock wave in the second 
chamber. The second chamber has outlet means 7 to permit 
a pulse of energy to be transmitted from the second 
chamber in response to the shock wave generated in the 
second chamber. The flap valve member can be arranged to 
be openable such that full bore opening of the bore 24, 
loss of gas pressure from bore 24, and the response of 
piston 13 to cause communication between the chambers can 
all be achieved very rapidly.

Title: Redundancy decoder
Inventor: MCCLURE DAVID CHARLES
IPC: G11C29/00
Filed: 1993-01-27
Abstract: An integrated circuit memory is disclosed which has its primary memory array arranged into blocks and which has redundant columns, each of which can replace a column in any one of the blocks. The redundant columns are selected by way of a redundant column decoder, associated with each column. A plurality of redundant sense amplifiers are each associated with selected redundant columns. Each of the redundant column decoders includes a set of address fuses for storing the column address responsive to which its associated redundant column is to be selected, and which are in series with pass gates which are turned on when redundancy is enabled, and turned off otherwise. This arrangement of address fuses and pass gates reduces and balances the loading of the decoder on the address lines, may be implemented with fewer transistors and thus in reduced chip area relative to conventional decoders, and also reduces the propagation delay through the decoder. The coupling of each redundant sense amplifier is controlled by a redundant multiplexer associated with each of the input/output terminals. Each redundant multiplexer receives the redundant column select signals from each redundant column decoder corresponding thereto, and includes fuses which indicate if its input/output terminal is to be placed in communication with its associated sense amplifier upon selection of a redundant column. <IMAGE>

Title: Thermoplastic structure, method of making and use.
Inventor: VONKEN HUB A G
IPC: B29C48/14
Filed: 1994-07-22
Abstract: A structure 1 produced by extrusion, such as a plastics foam sheet, a board, a profiled element or the like, contains at least 10 % by volume of open cells 2, 4, which have a polyhedral shape and adjoin one another. By using an increased temperature in extrusion, in comparison with the extrusion of closed-cell thermoplastic structures, the deformation-free opening of the cells is brought about. In that case, webs 3 of cell walls 5, 6 remain unaffected in their shape, whether they have openings 7 or no passages, so that mechanial strength of the cell framework or of the three-dimensional matrix is preserved. <IMAGE>

Title: Hand-operated shift actuator for multiple-gear bicycles
Inventor: PATTERSON SAM H
IPC: B62M9/131
Filed: 1992-03-18
Abstract: A bicycle gear shifting system having rotatable front and rear handgrip shift actuators (408,408h,408c,410) operatively associated with control cables (415,417) for shifting respective front and rear derailleur mechanisms. A shifter rotator (412,412b,412c,413) drives a separate "jack spool" (436,436a,436b,436c) which in turn actuates the control cable (415,417). A cam on the jack spool (436,436a,436b,436c) is configured so as to substantially compensate for increasing force of the derailleur return spring during down-shifting. Compensation is provided in the shift actuator for various lost motions in the derailleur shifting mechanisms and control cable systems. The shift actuator (408,408b,408c,410) also provides overshift movement of the derailleur mechanisms in the down-shifting direction so as to overshift the bicycle chain a sufficient amount beyond the destination derailleur sprocket so that the chain will approach the destination sprocket in the same direction as it would in the up-shifting direction. The shift actuator (408,408b,408c,410) also provides equalization for the higher derailleur return spring force during down-shifting than during up-shifting, and allow fine-tuning to avoid chain rasp, which is particularly important for "cross-over" riding.

Abstract: An electronic clock in which a time can be set securely and quickly at a stable rate
with favourable operability. The electronic clock is provided with an input time counting
means (103) for counting a time during which an input control means (102) detects a
continuous input signal sent from a switch (211) by using clock signals generated by a
frequency divider (101) for dividing down the frequency of a source oscillator (106), an
input time detecting means (104) for detecting the fact that a value obtained by this input
time counting means (103) reaches a predetermined value, and a setting
increment/decrement control means (105) for varying a setting increment or decrement (in
units of a unit time, e.g. one minute) to be added to or subtracted from a currently set value
of time every period corresponding to a clock signal generated by the frequency divider
(101). Further, this electronic clock is constructed in such a manner that the increment or
decrement is increased or decreased at a rate of 2 n  (n = 1, 2, 3, ...) if the input signal is
continuously input from the switch. Moreover, this electronic clock may be further
provided with a setting-digit selecting means (705) for selecting a time-setting digit, at
which a time is set, according to an output of the input time detecting means (703).
