Filed: 1989-09-13
Abstract: In a computer system, a CPU bus cycle control sec­
tion (211) receives a bus cycle request (BC-REQ) to gen­
erate a system bus request (SBC-REQ) and feeds back a 
ready notice (READY-a) to the CPU (11). A system bus

for delaying the ready notice (READY-b), a selector 
(214) for selecting one of the ready notice (D'READY) 
delayed by the timer (213) and the ready notice 
(READy-b) from the system bus cycle control section

abstract expressions.
Patent EP-0372390-A3 (EP)
Title: Method of and apparatus for establishing reference point on gradation correction curve
IPC: G06T5/40
Filed: 1989-11-30
Abstract: A highlight point (HL R , HL G , HL B ) and/or a shadow 
point (SD R , SD G , SD B ) on a gradation correction curve are 
established in consideration of decoloration and color fog 
of an original. Density values of respective primary colors 
are obtained for each pixel on an original. Average density 
is computed for each pixel and a cumulative histogram of 
average density distribution is generated. Temporary 
reference density values correspoending to prescribed 
cumulative frequencies are found on the cumulative 
histogram. Reference color density values (D RH , D GH , D BH ) 
are computed by averaging the density of each color for the 
pixels having average density between the temporary 
reference density and terminal density on the cumulative 
histogram. The highlight and shadow points are specified 
with one of the reference color densty values.

Title: Acrylic precursor for carbon fibres and method for its preparation
IPC: D01F6/38
Filed: 1989-11-28
Abstract: A method for preparing acrylic precursors with improved characteristics suitable for transformation into carbon fibres of superior mechanical characteristics comprises wet-spinning an acrylic polymer dissolved in dimethylacetamide followed by coagulation in a solvent-non solvent binary mixture bath of rigorously controlled composition and temperature, and a series of controlled-condition stretching operations with interposed washing stages, followed by yarn drying before its final collection. The method is characterised essentially by its coagulation stage, which is conducted under such rigorously controlled bath temperature and composition conditions as to obtain at the end of the process an acrylic yarn which has a perfectly compact structure practically free of flaws (voids), a perfectly circular cross-section and mechanical characteristics which are distinctly better than those of acrylic yarns of identical composition obtained by spinning processes of the known art. The specific destination of the acrylic yarn is the production of high-performance carbon fibres.

Title: Flat bed scanning type image reader
IPC: H04N1/10
Filed: 1990-05-25
Abstract: An apparatus for reading an image by using a CCD 
line sensor (18), including a half mirror (19) or the like dis­
posed on an optical path extending from an input opti­
cal system to the CCD line sensor, and a linear light 
source (22) disposed on an optical path branched out by the 
half mirror. The linear light source is located at a 
position equivalent to the CCD line sensor with re­
spect to a document table (11), and is equal in length to 
an effective pixel region of the CCD line sensor. 
Light emitted from the light source is projected back 
to the document table. An effective image reading 
area is displayed on the document table by relatively 
moving the document table and linear projected image 
in a sub-scanning direction.  
     The linear light source is rotatable in accord­
ance with a setting angle of an original. Consequent­
ly, an inclined image is projected back to the docu­
ment table to serve as a guideline for setting the 
original.  
     Where a spot light source is substituted for the 
linear light source, a spot image projected back to 
the document table is moved along a trimming area of 
an original. The trimming area is automatically 
determined by detecting distances of movement of the 
 
 
spot image.
