Title: Semiconductor device comprising a field effect transistor
IPC: H01L29/861
Filed: 1988-02-26
Abstract: A semiconductor device comprising a semiconductor 
substrate (1), a field effect transistor (Q) formed in 
the substrate (1), and a diode (D) connected to the 
field effect transistor (Q) and formed on the insulation 
film (11) formed on the substrate (1). Since the diode 
(D) is electrically insulated from the substrate (1) by 
the insulation film (11), no parasitic PNPN thyristor is 
formed in the semiconductor substrate (1). Therefore, a 
latch-up is prevented from occurring in the semiconduc­
tor device.

Patent EP-0284276-A3 (EP)
Title: Selective power gating
IPC: G11C11/413
Filed: 1988-03-16
Abstract: The invention is generally directed to a selective 
power gating device for providing power from a power supply 
to an electrical device adapted to receive at least two levels 
of power. A detection mechanism coupled to the electrical 
device determines a selected portion of the electrical device 
which requires a higher level of power. A power gating 
mechanism coupled to the detection mechanism and the power 
supply supplies a higher level of power to the selected portion 
and a lower level of power to a remaining portion of the 
electrical device. As a result, the overall power and heat 
generated by the electrical device is substantially reduced.

Patent EP-0327090-A3 (EP)
Title: Optical recording/reproducing apparatus
IPC: G11B7/0033
Filed: 1989-02-02
Abstract: A laser beam from a laser source (1) is incident on 
a track (8) of an optical card (7) through an objective 
lens (3). Since the optical card (7) is reciprocated 
along a track direction, the laser beam is scanned on 
the track (8). The light beam reflected by the optical 
card (7) is guided to a photo-detector (6) through the 
objective lens (3) and a mirror (5). An objective lens 
actuator (2) and an objective lens position sensor (4) 
are arranged near the objective lens (3). The objective 
lens actuator (2) performs tracking of the laser beam by 
moving the objective lens (3) in a direction perpen­
dicular to the track (8), and focuses the objective lens 
(3) by moving it in a direction perpendicular to the 
optical card (7). The lens position sensor (4) detects 
the displacement of the lens (3) during tracking. A 
track-error signal generated from the photo-detector (6) 
is supplied to the actuator (2) through a phase compen­
sate circuit (23) and a power amplifier (24), thus 
performing tracking servo control. An output from the 
lens position sensor (4) is supplied to an off-track 
detector (25). The off-track detector (25) is consti­
tuted by a low-pass filter (51) for cutting a high-­
frequency component, such as noise, a DC-cut circuit 
(52), and a window comparator (53).

Title: Process for producing grain-oriented thin electrical steel sheet having high magnetic flux density by one-stage cold-rolling method
IPC: C21D8/12
Filed: 1989-03-17
Abstract: The present invention provides a grain-oriented 
electrical steel sheet having a thickness of up to 
0.17 mm and excellent product magnetic characteristics. 
The present invention is characterized in that a silicon 
containing acid-soluble Al, N and Sn is used as the 
starting material, the N and acid-soluble Al contents in 
the slab are adjusted to 0.0050 to 0.0100% and {(27/14) 
x N (%) + 0.0035} to {(27/14) x N (%) + 0.0100}%, 
respectively, the thickness of the hot-rolled sheet is 
adjusted so that the thickness reduction ratio at the 
one-stage cold-rolling is 85 to 92%, and the Nas AlN 
content in the hot-rolled steel sheet is controlled to 
0.0005 to 0.0020%.
Patent EP-0336247-A3 (EP)
Title: Method and apparatus for digital transmission of information in short wave radio networks
IPC: H04K3/00
Filed: 1989-03-25
Abstract: For the purpose of channel state estimation at the receiver end, a reference signal (fq(t)) is added to and is transmitted with the data signal (fi(t)) containing the actual information. The addition of the reference signal (fq(t)) to the data signal (fi(t)) is effected by means of a quadrature modulation with the reference signal on the Q-axis and with the data signal on the I-axis, the envelopes being selected so that the magnitude of the complex envelope is constant. The receiver has a function stage for preprocessing the receive signal, for quadrature detection of the data signal elements and reference signal elements (yi) and (bi) respectively, for selection of the data/reference signal and for estimating the channel state. This permits the operation of non-linear final stages of the transmitter and a maximum energy output from the transmitter, and the requirements of the short-wave transmission such as very low signal-to-noise ratio and signal interference ratio, fading, slightly drifting local oscillators and time bases, as well as high noise burst frequency are taken account of in an optimum manner. In addition the send signal has a narrow bandwidth and a low sensitivity to bit slip, which increases the connection probability and the robustness of the transmission.

Patent EP-0369299-A3 (EP)
Title: Image data processing apparatus
IPC: H04N1/04
Filed: 1989-11-07
Abstract: A single facsimile apparatus performs both transmission 
and reception. A conventional facsimile apparatus, 
therefore, needs to have a paper feed mechanism for 
transmission to convey an original document read by an image 
sensor and another paper feed mechanism for reception to 
convey a recording sheet to be printed by head print image 
data on it, and as a result, its body has been large in 
size.  
     A facsimile apparatus by the present invention has a 
single conveying roller (28) in it, which an image sensor 
(26) is set above and a printing head (29) is set below. 
Pressing pins (46, 47, 48, 49) are set respectively near the 
upper and lower ends of components (43, 44) supporting the 
conveying roller (40) to freely rotate. In transmission, 
the lower pressing pins (46, 48) keep away the printing head 
(29) from the conveying roller (40) and the image sensor 
(26) presses an original document (57) onto the conveying 
roller (40). In reception, the upper pressing pins (45, 47) 
keep away the image sensor (26) from the conveying roller 
(40) and the printing head (29) presses the recording paper 
(31) onto the conveying roller (40). In this way, structure 
of the facsimile apparatus (21) is simplified.

Title: Rfi shielding gasket
IPC: H05K9/00
Filed: 1989-06-16
Abstract: The connection and shielding system for modular RF circuits encases modular 
circuitboards (10) within five-sided enclosures (11). The sixth side of each enclosure is 
provided by the top ground plane of a base circuitboard (20) that supports and electrically 
interconnects the components of the modular circuitboards (10). Enclosures (11) are fixed 
to a grounded metal socket formed by fence strips (22) and metal inserts (23) which form 
upwardly open slots including yieldable longitudinal gaskets (50). Gaskets (50) yieldably 
grip the open end of enclosures (11) and seal them against escaping radiation. Further 
radiation shielding is provided about the base circuitboard (20) by the fact that the 
conductive signal traces provided in it are sandwiched between two continuous ground 
planes and run between plated-through vias joining the ground planes. The ends of each 
enclosure are provided with double wall baffles (17, 18) which provide airflow to the 
interior and RFI shielding through offset open apertures (13).
Patent EP-0357229-A3 (EP)
Title: Acrylic hot melt pressure sensitive adhesive compositions
IPC: C09J155/00
Filed: 1989-07-31
Abstract: Acrylic hot melt pressure sensitive adhesive 
compositions having a good balance of tack, peel and 
creep resistance at ambient temperature combined with 
optical clarity and desirable melt viscosity at 
elevated temperatures are prepared by copolymerizing 
acrylic and methacrylic alkyl esters of a non-tertiary 
alcohol or optionally acids with polymerizable poly 
methacrylate based macromonomers. The resulting 
acrylic copolymer has a graft or comb structure in 
which the acrylic backbone has a low Tg and the pendant 
macromonomer side chains have a Tg above room 
temperature.  
     Compounding these acrylic copolymers with 
tackifiers and plasticizers dramatically improves the 
balance of pressure sensitive adhesive properties while 
lowering melt viscosity into a desirable range. The 
invention provides significant property enhancements 
even for acrylic copolymers having poor initial peel 
and shear adhesive properties. Preferably, the acrylic 
backbone is tailored by judicious selection of acrylic 
comonomers to allow compounding with several high 
performance hydrogenated tackifiers and plasticizers 
that provide water white and clear adhesive 
formulations while ensuring long term color stability, 
weatherability and general durability.
Patent EP-0363125-A3 (EP)
Title: Proliferated pancreatic endocrine cell product and process
IPC: A61P3/08
Filed: 1989-10-02
Abstract: Proliferated human fetal pancreatic cells comprising a mixture 
containing proliferated human fetal pancreatic islet progenitor 
cells, the proportion of pancreatic islet progenitor cells to 
exocrine and fibroblast cells being substantially greater than in 
fetal pancreas. The mixture can be in a culture medium, having 
pancreatic islet progenitor cells on or dispersed in a substrate 
matrix which can include collagen. It should be substantially free 
of fibroblast cells (preferably less than 10 percent), and can be 
in the form of droplets or other shapes suitable for implantation.  
     These progenitor cells are prepared by culturing human fetal 
pancreatic cells containing pancreatic islet cells, pancreatic 
islet progenitor cells, exocrine cells, and fibroblast cells; 
separating the epithelial cells containing the islet progenitor 
cells from the fibroblasts by subculture; and proliferating the 
pancreatic islet progenitor cells through one or more subcultures 
until the relative proportion of the pancreatic islet progenitor 
cells to fibroblast and exocrine cells and the total number of 
pancreatic islet progenitor cells is substantially greater than in 
the original fetal pancreas.

Title: Railroad vehicle
IPC: B61C9/52
Filed: 1989-11-08
Abstract: A railroad vehicle in which power is transmitted by 
a right angle cardan system and the body (1) of which is 
inclined by a natural pendulum system. In a 
construction based on a right angle cardan system in 
which the axis of an output shaft (4S) extends in the 
longitudinal direction of the vehicle, two prime movers 
(4) are mounted on one vehicle body in the vicinity of 
the centre thereof so as to face in the opposite 
directions, or one prime mover (4) having a pair of 
output shafts (4S) disposed at its opposite ends is 
mounted on the vehicle body generally at the centre 
thereof, and power is transmitted from each output shaft 
(4S) to the corresponding one of axles (10)disposed at 
longitudinal ends of the vehicle through a propeller 
shaft (3). The pair of propeller shafts (3) are rotated 
in opposite directions by the corresponding output 
shafts (4S), thereby cancelling the reaction torques 
produced when the output shafts (4S) rotate with equal 
torques. There is therefore no possibility of the 
vehicle body being forcibly inclined. It is therefore 
possible to smoothly incline the vehicle body by the 
natural pendulum effect.

Title: Video control system
IPC: G08B13/196
Filed: 1990-12-13
Abstract: Infrared light barriers or video control systems are used, as is known, in monitoring bounded, plane areas, for example a level crossing. However, both solutions have the disadvantage that they are unreliable or are of a very complicated design. The invention provides a video control system which permits reliable evaluation using simple means. For this purpose, a camera is used to take and store two fields in each case, one being taken without flash, and the other with. A differential image, now containing only signal components caused by the light of the flash is obtained from the two fields. Given the presence of a three-dimensional object in the monitored area, there is produced on the side of the object averted from the flash a shadow signal which is evaluated and, if necessary, fed to the alarm-triggering device. <IMAGE>
Patent EP-0385541-A3 (EP)
Title: Butter containing spread and process for preparation thereof
IPC: A23C15/16
Filed: 1990-02-23
Abstract: The present invention relates to a butter-containing 
spread, and a process for the production of the said 
spread.  
     The present invention provides an edible emulsion 
comprising 30-70%wt of an aqueous phase CHARACTERISED IN 
THAT it comprises both wet-concentrated and dry 
butterfat in a weight ratio of 1:10 to 10:1. It is 
believed that one advantage of using both wet and dry 
butterfat components stems from the difference in the 
organoleptic properties of these two components. The 
term wet-concentrated butterfat is intended to embrace 
within its scope both concentrated cream, having a fat 
content in excess of 40%wt and butter. Dry-butterfat is 
intended to embrace butter-fats which have been rendered 
anhydrous at some time during the concentration process. 
The dry butterfat component contributes a different set 
of flavour components to the product. It is believed 
that rendering the butterfat anhydrous causes the 
formation of flavour components which are not present in 
fresh dairy butter or cream.
