Patent EP-0388715-A3 (EP)
Title: Graphic material registration apparatus and method
IPC: G03B27/20
Filed: 1990-03-08
Abstract: A method and an apparatus for supporting photographic sheet 
materials (9,11) in intimate surface contact during contact 
exposure includes a flexible membrane (15) which forms a 
common boundary wall between two gas-tight chambers. Air at 
ambient pressure is admitted to one chamber at a controlled 
rate slower than air is evacuated from the other chamber 
containing the photographic sheet materials. Progressive 
expansion of the surface area of contacting force assures 
that residual volumes of air between photographic sheets 
(9,11) are squeezed out in an orderly pattern and not 
trapped in isolated pockets that would distort resulting 
photographic images.

Title: Spread spectrum communication system
IPC: H04J13/00
Filed: 1990-04-14
Abstract: The spread spectrum digital communication system includes 
data input devices for generating digital information signals to 
be transmitted using radio signals. A chip stream generator 
converts the data bits into chip streams that are either 
complemented or not complemented via an exclusive-OR gate, 
depending on the data bits. A scrambler further randomizes the 
chip stream for transmission. The receiver includes a descrambler 
and a correlator or digital matched filter for detecting the data 
signal. A modified receiver includes a sampler for sampling the 
scrambled signal at a rate which is the multiple of the chip rate 
thereby eliminating any need for recovering the chip clock. 
Another modified version includes a receiver having means for 
generating multi-level signals indicating the quality of the 
probable detection.

Title: Method and apparatus for validating a paper-like piece
IPC: G07D7/12
Filed: 1990-06-16
Abstract: An apparatus and method for validating a paper-like 
piece are of a type having a detector which irradiates 
light onto a deposited paper-like piece and thereby 
produces a detection signal corresponding to a pattern 
on the paper-like piece and validating the paper-like 
piece by collating the detection signal produced by the 
detector in response to deposition of the paper-like 
piece with a predetermined standard pattern. Features 
of the apparatus and method are that a reference paper-­
like piece having no particular pattern is deposited and 
reference level data is obtained on the basis of a 
detection signal produced by the detector in response to 
this deposition, that data to be examined is provided by 
converting a detection signal produced by the detector 
in response to deposition of a paper-like piece to be 
validated to a ratio to or deviation from the reference 
level data and that validation is made by collating this 
data to be examined with the standard pattern. Since 
the base for normalizing measured data for collation is 
set at the level of the reference paper-like piece, 
validation becomes less vulnerable to adverse effects by 
a parts error and an assembling error in an optical type 
 
 
detector with resulting improvement in the validation 
accuracy.

IPC: G11B5/31
Filed: 1990-03-19
Abstract: In a magnetic recording apparatus with a 
magnetic head, superconductive layers (6, 17, 106) are 
formed over at least flux generating surfaces of the 
magnetic head and normal conductive regions (8, 21, 108) 
for passing the flux are provided in the superconductive 
layers, over the flux generating surfaces, so as not to 
form a closed magnetic circuit. The minimum unit size 
(recording wavelength) of the reversible spontaneous 
magnetization in magnetic recording can be reduced from the 
order of 1 µm to that of 0.1 µm of submicron. Thus 
it is possible to increase the surface recording density 
of magnetic recording to more than 100 Mb/in², comparable 
to the density achieved by the opto-magnetic recording. 
This in turn makes it possible to provide a large disc 
apparatus having a capacity of 60 MB or more.

Title: Edge emission type el printer and the printing method thereof
IPC: B41J2/45
Filed: 1990-04-17
Abstract: Disclosed herein is a line printer that operates on a 
novel printing method. In the printer, an input print 
signal is stored temporarily per primary scanning line. 
The signal thus stored for each primary scanning line is 
output a plurality of times to a line head so that the 
head generates as many emissions to produce one primary 
scanning line in the primary scanning direction. This 
makes the edges of each printed primary scanning line not 
serrated but substantially flat with no spurious white 
dots left in pixels even when EL devices of the line head 
generate flatly polarized beams of light.

Patent EP-0400989-A3 (EP)
IPC: G01N30/46
Filed: 1990-05-30
Abstract: A sample of a hydrocarbon oil containing 
asphaltenes is chromatographically analyzed by forming 
a mixture of the oil with a weak solvent. The mixture 
is passed in contact with a column of a stationary 
phase of fine solid particles of fully functionalized 
material, followed by a weak solvent. The solvent, 
after recovery from the column, is analyzed for 
aromatics by UV-absorption of UV radiation in the range 
200 to 500 nm. The absorbance of the UV light by the 
irradiated eluents across the UV wavelength range is 
monitored and the integral of absorbance is derived as 
a function of photon energy across the wavelength 
range. The magnitude of the derived integral in at 
least one time interval corresponding with aromatics in 
the eluent from the stationary phase is measured as an 
indication of the level of aromatics in the oil sample. 
The weak solvent may be followed by a strong solvent 
which, in turn, may be followed by a strong solvent 
which is modified by the addition of a hydrogen bonding 
solvent. The solvents are analyzed for saturates, 
aromatics, polar compounds and any asphaltenic 
materials by the combination of the UV-absorption 
measurement and a mass sensitive measurement which 
measures the combined level of the saturates, 
aromatics, polars and any asphaltenic compounds 
present. Equipment to perform the foregoing analysis 
is also described. The analysis can be used for 
evaluation of an oil and/or for on-line regulation of 
an oil refining process.

Title: Apparatus for preventing computer data destructively read out from storage unit
Inventor: KANEKO HIROYUKI
IPC: G06F11/00
Filed: 1992-08-24
Abstract: A data transfer control system for a computer can prevent destructive read out of data from an external storage unit during a data transfer operation. To control transfer of a series of data between a first storage unit (5) having a first storage capacity and a second storage unit (1) of a computer, having a second storage capacity typically smaller than the first storage capacity, the apparatus employs a first buffer memory (29) for temporarily storing the series of data read out from the first storage unit, a second buffer memory (29) for temporarily storing the series of data transferred from the first buffer memory means, and a buffer checking/controlling unit for checking whether or not a storage condition of the second buffer memory means corresponds to an empty state. An empty flag is set when the second buffer memory (29) becomes empty. The buffer checking/control unit also controls transfer of the series of data from the first buffer memory (21) to the second buffer memory (29) and from the second buffer memory (21) to the second storage means of the computer in such a way that if, after the series of data is read out from the first storage unit (1) to the second storage unit (1), the empty flag is not set, an abnormal data transfer signal is issued to prevent destructive data read out from the first storage unit (5). Another embodiment comprises the last words of first and second buffer memories (21, 19) and, if they fail to coincide, issues an abnormal data transfer signal. The embodiments can be used separately or together. <IMAGE>   <IMAGE>

Title: Plant for separating floating and/or suspended matters from contaminated waste waters.
Inventor: SEHR GERHARD
IPC: B01D17/02
Filed: 1993-05-08
Abstract: Separator plants for sink material, in particular starch, and float material, in particular fats, for small waste water (effluent) quantities are to be made cheaper in terms of construction and simplified with respect to disposal. Adaptation to the volumetric flowrate existing on site is likewise to be readily possible. The novel separator plant which achieves this object is characterised in that all feed and outlet and discharge lines are conducted through the covers of the settling tanks and the covers themselves are easily detachably attached. In this manner modules are formed to which in particular standardised tanks of the desired size can be applied. Together with quick-release couplings for the external piping, rapid dismantling of the functional unit is also possible for disposing of the waste of the entire tanks. The plant can be installed complete on a small trailer and then brought to changing sites of use, such as mobile dishwashers. Waste disposal is likewise performed on the trailer.
Patent EP-0592783-A3 (EP)
Title: Heat regulator for integrated circuits
Inventor: KENNY JOHN D
IPC: G06F1/08
Filed: 1993-08-05
Abstract: The temperature of a circuit is monitored and controlled by accumulating an estimate of heat generated in the circuit, and decreasing heat generation in the circuit when necessary. A periodic sampling of the operating mode of the circuit, as determined by clock speed and bus cycle activity, is used to determine heat accumulation in the circuit. An up/down counter increments when the sampling shows an operating mode indicating heating of the circuit and decrements when the sampled mode indicates cooling of the circuit. The circuit is forced to cool if a count on the up/down counter reaches a programmable threshold. Cooling is accomplished by slowing the clock speed of the circuit. <IMAGE>
