Patent EP-0319858-A3 (EP)
IPC: H01L21/18
Filed: 1988-12-02
Abstract: A method of controlling a floating zone applied to a 
crystal manufacturing system based on the FZ method and 
designed to enable the diameter at the crystallization 
boundary and the axial length of the floating zone or other 
similar quantities to desired values, in which a floating 
zone (20) is imaged with an imaging device (30); geometric 
quantities of the floating zone is measured from the image 
thereby obtained; the electric power (P) supplied to an 
induction heating coil (12) and the speed (V P ) at which a 
raw-material rod (16) is moved relative to the induction 
heating coil so that the geometric quantities become equal 
to desired values. The geometric values include one Z i  of 
the axial length of the floating zone, the distance (L) 
between the induction heating coil and a crystallization 
boundary (24) and the diameter (D n ) of a melt neck portion 
located on the side of the crystallization boundary at a 
predetermined distance from the induction heating coil, and 
one D i  of the diameter (D s ) of the crystallization boundary 
and the diameter (D m ) of a melt shoulder portion (34) 
located between the crystallization boundary and the 
restricted portion at a predetermined distance (h m ) from the 
crystallization boundary.  
     If a desired value of the Z i  is Z o , a desired value of the 
D i  is D o  and M = (Z i  - Z o ) (D i  - D o ),  
 
 
the contribution of control of the relative speed (V P ) 
is smaller when Z i  = Z o  and D i  = D o  are not satisfied 
substantially and M > 0 than it is when Z i  = Z o  and D i  = D o  
are substantially satisfied (104, 106), and  
the contribution of control of the electric power (P) 
is smaller when Z i  = Z o  and D i  = D o  are not satisfied 
substantially and M < 0 than it is when Z i  = Z o  and D i  = D o  
are satisfied substantially (112, 122).

Patent EP-0316112-A3 (EP)
IPC: G10L15/10
Filed: 1988-11-03
Abstract: Any of several prior art word recognizers are improved by changing 
the speech analysis portion thereof to 
include a more comprehensive spectral 
representation which can be characterized as two-dimensional. The first 
dimension is the "freeze-frame" or instantaneous sample of the spectral 
characteristics as derived from a typical 45 
millisecond sample of the speech to be 
recognized. The second dimension, in a sense 
orthogonal to the first, spans 
several such time frames or samples and 
yields what amounts to a time derivative 
of the spectral properties obtained in the current time frame. 
In the testing or processing of the input speech 
in comparison to the reference patterns, 
essentially equal weight or effectiveness is 
attributed to both parts of the two 
dimensional reference spectral pattern and to 
both parts of the input speech spectral 
pattern. That is, equal importance is 
attributed to the essentially instantaneous 
information and the time-derivative 
information spanning a plurality of neighboring 
time frames including the frame 
of interest.  
     Also disclosed are the use of cepstral 
information and time-derivative 
cepstral information derived from linear 
prediction coefficient methods and the use 
specifically in connected-word recognizers 
using level-building concepts, or in 
those using two-stage processing.

Title: Method of manufacturing main plates for exposure printing
IPC: G03F1/00
Filed: 1989-05-23
Abstract: In order to manufacture a pair of main plates (110, 
111) closely contacted with both the faces of a member 
to be exposed to light, patterns (114, 126) are drawn 
on a pair of original dry plates (112, 124) by a main 
pattern drawing device and developed. Thereafter, the 
developed pattern formed on one of the pair of original 
dry plates is successively transcribed even times in 
such a manner that a transcribed pattern having just 
formed on a newly supplied dry plate at a prior tran­
scription is now transcribed to a fleshly supplied dry 
plate at a next transcription, and the developed pattern 
formed on the other one of the pair of original dry 
plate is successively transcribed odd times in such a 
manner that a transcribed pattern having just formed on 
a newly supplied dry plate at a prior transcription is 
now transcribed to a fleshly supplied dry plate at a 
next transcription, thereby forming a pair of main 
plates.

Patent EP-0373583-A3 (EP)
IPC: C07C229/36
Filed: 1989-12-12
Abstract: A method for the isolation of a substantially pure L-isomer of an 
amino acid from its D,L racemic mixture does not require the use 
of a resolving agent, the formation of a derivative of the amino 
acid or additional enzymic reactions. The method is based upon 
the concept of the equal saturation point wherein the L-isomer 
can be separated from the D-isomer by precipitation of the 
L-isomer when the relative concentration of the D-isomer is less 
than 7.0% or by precipitation of the D,L racemate when the 
relative concentration is greater than 7.0%. Selective 
crystallization through seeding allows for further isolation of 
pure L-isomer when its relative concentration in solution is very 
low.

Patent EP-0333407-A3 (EP)
Title: Resist material and process for information of resist patterns
IPC: G03F7/38
Filed: 1989-03-13
Abstract: A pattern-forming resist material comprises a 
water-soluble polymeric material having at least one 
hydroxyl group in the molecular structure thereof and a 
photo-acid generator which, during exposure to 
radiation, does not cause cross-linking of the 
polymeric material, but release an acid upon reaction 
with the polymeric material. The resist material may 
be negative-working and is particularly suitable for 
deep ultraviolet exposure. On heating, the acid causes 
dewatering of the unsolubilizing polymeric material so 
that the resist material can be developed with water to 
form very fine resist patterns without swelling thereof.

Patent EP-0403265-A3 (EP)
IPC: B60B33/02
Filed: 1990-06-13
Abstract: Problems exist in known forms of steerable mobile 
load carriers, e.g. shopping trolleys. Trolleys with 
four swivel castors (1.4) are difficult to steer, 
particularly on slopes, and if two castors are fixed 
to improve steering, a stack of trolleys is very 
difficult to manoeuvre.  
     An arrangement is therefore used in which one 
pair of castors (3.4) are normally inhibited from 
swivelling, but are released when nested. In the 
normal state, each of these castors is prevented from 
swivelling in a respective one of two opposite 
directions but allowed to swivel in the other 
direction. This arrangement ensures good reverse 
manoeuvrability while providing both improved control 
over forward movement and the desired manoeuvrability 
of a trolley stack.
