Patent EP-0291035-A3 (EP)
IPC: G02B26/10
Filed: 1988-05-11
Abstract: A light beam deflection scanning method including the 
steps of: (a)finding data for cancelling an amount of 
distortion of a scanning track 
(of a light beam which is focussed on the surface by a 
scanning lens), for each falling position of the light 
beam on the surface, the distortion being caused and 
specified by the characteristic of the lens; (b) directing 
the light beam at the surface through the scanning lens and 
deflecting the light beam in a main scanning direction; (c) 
detecting the falling position of the light beam on the 
surface; during the deflecting in step (b), deflecting the 
light beam in a subscanning direction by an amount based on 
the data, to thereby cancel the distortion of the scanning 
track.

Title: A method for lr (left-right) table compression
IPC: G06F9/45
Filed: 1988-10-19
Abstract: A method for compressing an LR (Left-Right), LALR, or 
SLR parsing table into a compact and time-efficient 
representation which is machine and language 
independent, and allows access to table entries with 
a constant number of primitive operations. The 
primitive operations used: addition, comparison, and 
vector indexing, are in general very efficiently 
implemented on most machines, and are the key to the 
superior time performance of this method over other 
methods. Transformations are applied to the parsing 
table prior to compression that makes the method of 
the present invention competitive and very often 
superior to other space-efficient methods.

Title: Step data processor for 180x and 90x compass synchro data
IPC: G01D5/244
Filed: 1988-08-24
Abstract: A compass data converter converts 180X and 90X 
synchro compass data to 1/6 degree step data. 180X 
synchro data is converted by utilising a 360X to 1/6 
degree step data converter that divides the synchro 
rotation into six 60 degree sectors providing a digitial 
step data code representative thereof. A 180X converter 
further sub divides the 60 degree sectors into 30 degree 
sub sectors by selecting a synchro output in accordance 
with the step data code from the 360 X converter and 
comparing the selected synchro output to ground to 
provide an additional step data digit. The converter for 
90X data further sub-divides the 30 degree sub-sectors 
into 15 degree intervals by selecting two synchro outputs 
in accordance with the 360X step data code and the 
additional step data digit and scaling one of the 
selected synchro outputs to equal the other selected 
synchro output at the 15 degree interval boundaries. A 
comparison of the selected unscaled synchro output and 
the selected scaled synchro output provides a fifth step 
data digit for the 90X code.

end temperature). The article is preferably tubular, and 
the electrical behaviour allows it to be conveniently 
electroded with elongate electrodes, while avoiding 
overheating during recovery.

Title: Manipulator control method and system
IPC: B25J9/18
Filed: 1989-06-09
Abstract: After positional information of the master arm 
(101) is transformed into first generalized coordinates 
corresponding to positional information representing an 
instruction position of the slave arm (102), when a 
signal instructing an interruption of the associated 
operation between the master arm and the slave arm is 
received and then the positional relationships between 
the master arm and the slave arm connected thereto by 
use of an imaging device (109) are updated, the first 
generalized coordinates are transformed into the second 
generalized coordinates based on the new positional 
relationships so as to restart the associated operation 
therebetween. The optimal control of the manipulator is 
conducted through matrix operations related to the 
change-over between imaging devices, the reset operation 
conducted in an area of the movable range of of the master 
arm, and the alteration of the ratio between the movements 
of the associated operation.

Title: Synchronisation method for a clock generator, especially of a clock generator of a digital telephone exchange
IPC: H03L7/14
Filed: 1989-06-14
Abstract: When the reference clock (fr) fails for a short time, the voltage-controlled oscillator (VCO) of the phase-locked loop (PLL), the output clock of which determines the clock of the clock generator, continues to be operated with the control output voltage valid until then. When the reference clock returns, the phase difference between reference clock (fR) and output clock (fn) of the oscillator is again measured and corrected with the value of the corresponding phase difference valid before the failure of the reference clock. The corrected value is used as a basis for the resumed frequency control.
