Title: Balanced drive photosensitive pixel and method of operating the same
IPC: G09G3/30
Filed: 1987-01-20
Abstract: A pixel includes an active element 40 interconnected with a group of at least two series connected blocking elements, 34,36 at a nodal point 38, between the blocking elements 34,36. In a preferred embodiment, the capacitances of the individual blocking elements are substantially equal thereby enabling capacitive kick during the addressing of the pixel to be reduced. The invention may be readily adapted to provide both linear and two dimensional pixel arrays adapted to function as display devices and photosensors, and having high accuracy, fast access times and high resolution. A method of operating the pixel using balanced driving signals is also disclosed.

IPC: C01B33/02
Filed: 1987-04-15
Abstract: Es wird ein Verfahren zur Herstellung von Formkörpern 
aus Granulat auf der Basis von Silicium, Germanium oder 
Mischkristallen dieser Elemente angegeben. Das in einer be­
stimmten Raumform vorgelegte Granulat wird dabei Bed­
ingungen unterworfen, die den Beginn und Fortgang einer 
chemischen Transportreaktion gestatten, die unter Transport 
von Silicium bzw. Germanium abläuft. Dadurch verwachsen 
die Granulatkörner miteinander und bilden schließlich einen 
festen, porösen Formkörper. Durch Variation des Ausgangs­
materials, des Transportmittels sowie ggf. durch Zusatz von 
Dotierstoffen lassen sich insbesondere die elektrischen 
Eigenschaften des Produktes beeinflussen.

Patent EP-0277316-A3 (EP)
IPC: A01K63/00
Filed: 1983-07-26
Abstract: The container is preferably of double-wall construction and 
fabricated of high density polyethylene or 
other high strength material suitable for contact with 
foodstuffs. Polyurethane insulation may be foamed into place 
within the double walls during fabrication to further rigidify 
the structure and to reduce the melting of ice packed with fish 
into the container.  
     The vertical stacking strength of the containers is 
enhanced by the inclusion of a series of exterior vertical 
corrugations (1) formed in side walls (3) and end walls (5). 
Bottom wall (4) is strengthened by a series of 
exterior horizontal corrugations (6).  
     The upper portions (7) of the side walls (3) extend 
vertically beyond the tops (9) of the end walls (5). The bottom 
portions (11) of the side walls (3) are inwardly recessed a 
sufficient amount that the bottom portion of the container is 
of a reduced width dimensioned to be received between the 
extending upper portions (7) of the side wall (3) of a similar 
container container stacked vertically therebelow.  
     Preferably, the vertical dimension of the bottom 
portion of the container of reduced width is slightly less than 
the vertical dimension of the upper portions 7 of the side 
walls 3 extending beyond the tops 9 of said end walls 5 to 
allow for the thickness of container covers 
in the stacking of containers one above the other.
Patent EP-0265016-A3 (EP)
IPC: H02K15/03
Filed: 1987-10-19
Abstract: A rare earth transition metal magnet, such as SmCo5, is 
pressed from alloy powder in an intense aligning magnetic field 
before sintering. This involves adapting a standard press to 
accommodate an electromagnet which latter makes it impractical to 
form a multipolar aligned magnet in one piece.  
     In the improvement a comminuted alloy of neodymium iron and 
boron is pressed in a chamber (31) in the less intense aligning 
magnetic field generated by permanent magnets (34), e.g. of SmCo5 
or NdFeB. The pressing chamber assembly (32, 33, 34, 35) is 
compact and can be used on an unmodified press (3, 5, 36, 37) to 
provide a multipolar aligned NdFeB magnet having a remanence 
greater than that of a SmCo5 magnet.

Title: Method of enclosing an object within a homegeneous blockmethod of enclosing an object within a homegeneous block (1) (1)
IPC: H01H69/02
Filed: 1987-04-13
Abstract: A method of enclosing an object (5), such as an electronic component, within a homogeneous block of microporous thermal insulation material comprises charging a first predetermined amount of a loose microporous thermal insulation mixture (2) into a die (1) and compacting the insulation mixture into a block for supporting the object to be insulated. A recess (4) may be formed in the compacted mixture for receiving the object (5). The object (5) is then located on the compacted mixture and a second predetermined amount of loose microporous thermal insulation mixture (6) is charged into the die (1). The loose insulation mixture (6) is compacted against the block of already compacted insulation material (2) which causes the two charges of insulation mixture to merge and to form a homogeneous block enclosing the object.

Title: Furniture for the wing of a window, door or the like which is at least tiltable and adjustable in a parallel position
IPC: E05B15/10
Filed: 1989-04-01
Abstract: So that a furniture, by means of which a wing (2) can be transferred from a locking position into an unlocking position and tilting position, is prevented from changing over undesirably from the tilting position to a parallel parking position, a releasable blocking device (10) is located on the lower horizontal spars of the frame (1) and of the wing (2). The release is obtained by means of the rotary handle (8) which also causes the unlocking. The blocking device (10) can be retained, by means of a blocking apparatus (15) installed according to the invention, in an inoperative position which makes it possible for the wing, without being impeded by the blocking device (10), to be moved as often as desired from the parallel parking position into the tilting position and vice versa. <IMAGE>

Abstract: A percussive-action mole 10 is energised by compressed air 
supplied through hollow rods 36 in a string 12 connected 
to the mole. A hydraulic motor 18 rotates the string and 
mole. The mole head 30 has a slant face 32 and a 
transverse permanent magnet 34. After each new rod is

which continues to be rotated. The field fluctuations 
from the magnet are detected by a magnetometer 24 using 
its probe at three positions 50, 52, 54 determined by a 
triangular frame 22 placed flat on the ground. 
Calculations using the three readings each representing 
the distance of the magnet from the respective position on 
the frame enable the position and depth of the magnet to 
be determined. After completion, the passage 38 can be 
reamed to larger diameter to receive a gas pipe or other 
service.

Title: Exposure mask, method of manufacturing the same, and exposure method using the same
IPC: G03F1/00
Filed: 1990-02-13
Abstract: An exposure mask for lithography, a method of 
manufacturing the same, and an exposure method using the 
same are disclosed. A light-transmitting opening of the 
exposure mask has a main light-transmitting region 
located in the middle of the opening and having a first 
optical path length, and phase shift regions adjacent to 
a light-shielding layer and having a second optical path 
length, different from the first optical path length. 
Light transmitted through each phase shift region 
interferes with light transmitted through the main 
light-transmitting region at the edges of the light-­
transmitting opening, thus enabling a sharp photo-­
intensity distribution of total transmitted light to be 
obtained. As a result, the resolution of the exposure 
mask is improved.
