Patent EP-0345494-A3 (EP)
Title: Opto-electronic memory device
IPC: G11C13/04
Filed: 1989-05-17
Abstract: A fully optical random access memory device is 
disclosed having an opto-electronic substrate. A write 
beam, having a wavelength within the absorption band of 
the opto-electronic substrate, and a read beam, having a 
wavelength outside the absorption band of the opto-­
electronic substrate, are used to read and write

Patent EP-0345701-A3 (EP)
IPC: H01L21/66
Filed: 1989-06-05
Abstract: Für den Entwickler mikroelektronischer Bauelemente ist die 
Kenntnis der Latch-Up-Ausbreitung in integrierten CM0S-Schaltun­
gen von entscheidender Bedeutung, um deren Latch-Up-Empfindlich­
keit durch Änderungen des Designs oder technologische Maßnahmen 
verringern zu können. Da die bekannten Verfahren zur Untersu­
chung der Latch-Up-Ausbreitung nur eine vergleichsweise geringe 
zeitliche Auflösung besitzen, wird vorgeschlagen, den Latch-Up 
periodisch auszulösen, die Intensität der von der Schaltung 
ausgehenden Infrarotstrahlung an mehreren die Schaltung raster­
förmig überdeckten Meßstellen abzutasten, an den Meßstellen je­
weils festzustellen, innerhalb welcher Zeitspanne τ die Intensi­
tät der Infrarotstrahlung einen Schwellenwert erreicht und je­
weils einen die Zeitspanne τ repräsentierenden Meßwert ortsab­
hängig aufzuzeichnen.

Title: Image forming device
IPC: G03G15/08
Filed: 1989-10-25
Abstract: A toner hopper which is arranged upwards of the developing 
unit is elevatably supported in the image forming device 
in the vertical direction thereof. Therefore, as the 
connection thereof with the developing unit can be 
cancelled by lifting up the toner hopper when drawing out 
the developing unit, the structure of the connection 
portion therebetween can be simplified and the sliding 
portion can be eliminated, thereby causing the troubles 
due to wearing at the connection therebetween to be 
eliminated. Simultaneously, it is possible to provide 
means for automating the elevation and lowering of the 
toner hopper and means for maintaining the horizontality 
of the toner hopper when being elevated and lowered.

Title: Wavelength-division switching system for optical frequency-shift keying signals
IPC: H04B10/58
Filed: 1990-01-26
Abstract: An optical switching system comprises an input terminal for 
receiving an optical wavelength-division multiplexed (WDM) 
signal in which optical signals differing in center 
wavelength  i  (i = 1 to N) are wavelength-division 
multiplexed, the optical signal being an optical frequency-­
shift keying (FSK) signal which is a first optical FSK 
signal F i . A splitter splits the optical WDM signal 
correspondingly to the wavelengths λ i  to generate 
optical wavelength-corresponding WDM signals W i . 
Wavelength extracting circuits extract optical FSK 
signals F j  (j = 1 to N) pertaining to wavelengths λ j , 
to which the wavelengths λ i  are to be switched, from 
the optical wavelength-corresponding WDM signals W i  to 
generate optical amplitude-shift keying (ASK) signals A j  
pertaining to the wavelengths λ j  to be switched to. 
Wavelength switches switch the optical ASK signals A j  
to second optical FSK signals F i  corresponding to the 
wavelengths λ i . A wavelength multiplexer wavelength-­
multiplexes the second optical FSK signals F i  into an 
optical switched WDM signal. This optical WD switching 
system reduces the signal deterioration due to crosstalk by 
optical signals of wavelengths other than that to be 
selected when an optical signal of a certain wavelength are 
being selected by a tunable or a fixed wavelength filter.

Title: Process for the preparation of starch glues
IPC: C09J103/02
Filed: 1990-02-23
Abstract: The invention is a method of controlling the final viscosity of a starch glue at a constant starch content and an apparatus for carrying out the method. The invention concerns a process for preparing a starch glue in which part or all of the starch in the glue is partially swollen to a predetermined "critical" swelling viscosity when the swelling process is terminated and the "final" viscosity is only reached after a subsequent period of agitation. The method of the invention reduces the critical swelling viscosity during the process as the elapsed reaction time increases thereby ensuring a constant final viscosity at a constant starch content of the glue.

Patent EP-0698986-A3 (EP)
Inventor: WALKER MICHAEL
IPC: H04M9/08
Filed: 1995-08-11
Abstract: The method involves using an echo compensator with a finite impulse response (FIR) filter (5). The filter reproduces the expected echoes, which is then subtracted from the affected signal. The filter coefficients (c1,...cN) are determined according to a normalised least mean square algorithm (NLMS algorithm). The step width (alpha) in the NLMS algorithm is varied according to signal source (1) surrounding conditions, echo compensator efficiency and interference level. A normalising signal for the filter is determined from the largest coefficient and then for all coefficients so that coefficient values are dynamically scaled. The shortest signal path time from the source to a sink (2) is determined according to largest coefficient temporal distance. From this the effective range of the echo compensator is determined. This information is used to estimate the remaining rest coupling.
