Abstract: A plurality of slide access memories (SM₀₀ , SM₀₁ , 
..., SM n-1, m-1 ), in which a voluntary rectangular group 
of bits can be accessed, are arranged in an  n -rows and 
 m -columns matrix and connected to common data lines

memories to enable or disable the operation thereof in 
accordance with a special bit position, or a pointing 
bit (PB) position, to thereby connect only a desired 
group of bits to common data lines, and thus enlarge the

Abstract: Dual-Gate-Transistoren haben eine geringere 
Grenzfrequenz als Single-Gate-Transistoren.  
     Der erfindungsgemäße, steuerbare 
Wechselspannungsverstärker enthält einen 
Single-Gate-Feldeffekttransistor (F₁) in 
Sourceschaltung. Gateseitig liegt das zu verstärkende, 
hochfrequente Eingangssignal (U E ) an. Die Drain-Strom wird 
durch eine steuerbare Spannung (U St ) variiert; dadurch 
ändert sich die Verstärkung, während sich der 
Lastwiderstand beim Steuervorgang nicht ändert.  
     Die Steilheit S der Verstärkung der 
Single-Gate-Feldeffekttransistor, ist proportional zur Wurzel 
aus dem Drain-Strom.  
     Daher lassen sich mehrere

Title: Photopolymerizable resin composition
IPC: H05K3/00
Filed: 1989-10-24
Abstract: The present invention relates to a photo­
polymerizable resin composition developable with an 
aqueous weak alkaline solution and suitable for a printed 
circuit board.  
     The photopolymerizable resin composition of the 
present invention is mainly composed of: 
   (a) a linear acrylic copolymer,    (b) an ethylenically unsaturated compound, and    (c) a photopolymerization initiator, 
wherein said linear acrylic copolymer comprises as 
indispensable comonomers: 
   i) at least one compound represented by the 
following general formula:  
CH₂= 
-CO-Y-Z-OH    
wherein X is a hydrogen atom or a methyl group, Y is an 
oxygen atom or an imino grop and Z is an alkylene group 
having 1 to 5 carbon atoms, and    ii) an ethylenically unsaturated compound having a 
carboxyl group.      
the photopolymerizable resin composition of the 
present invention can afford a resist film having 
excellent flexibility and adhesion through the use of the 
above-described particular linear acrylic copolymer. 
Therefore, when, for example, a printed circuit board is 
prepared by making use of the photopolymerizable resin 
 
 
composition of the present invention, occurrence of 
defectives can be remarkably reduced because no crack 
occurs on the resist film and no etchant penetrates into 
the gap formed between the resist film and the surface of 
the board.

Title: Clustering and association processor
IPC: G05B13/02
Filed: 1990-04-13
Abstract: A clustering and association processor is disclosed 
for correlating sets (12) of two-dimensional data points (14). 
Clustering is performed by treating each data point (14) as a 
mass subject to gravitational attraction by other data points 
(14). The data points (14) are permitted to move in data 
space until all data points (14) in particular regions (16) 
of the data set (12) fall into a single point, or centroid 
(18). Individual data points (14) and correlated regions 
(16) of successive data sets (12) are then correlated by means 
of a resonant descent technique, which determines the distance 
and direction of individual data points (14) from a chosen 
data point. The processor then matches a pair of two data 
points (12) with the chosen data point which are equidistant 
and collinear with the chosen data point.

Title: Holder for molten metal sampling device
IPC: G01N1/12
Filed: 1990-01-18
Abstract: A holder for a molten metal sampling device includes 
a pipe (12) having a guidance chamber (18) in a lower 
portion and a molten metal sampling device (14) in an 
upper portion. The pipe is open downwardly and a closure 
element (24) closes the opening. The closure element has 
a density such as to cause it to float upwardly in the 
molten metal being sampled. A protective cover (40), 
preferably of two parts (42), enoloses the closure 
element and a lower portion of the pipe. A retaining 
device such as a spring clip (46) holds the separate 
parts of the protective cover together around the closure 
element and the lower part of the pipe. The retaining 
device is adapted to fail upon contact with the molten 
metal, thus releasing the portions of the protective 
cover so that they will separate and float upwards, 
whereupon the closure element also separates and floats 
away, allowing molten metal into the guidance chamber and 
the sampling device.
