Title: Heat-sensitive record material
IPC: B41M5/333
Filed: 1990-02-08
Abstract: The heat-sensitive record material, in which color images are produced 
by a color-forming reaction between a colorless or pale colored basic 
chromogenic material and a color developer, comprises a novolac-type epoxy 
resin or a diphenyl sulfone derivative represented by the formula (III) in 
the color forming reaction system.  
     In the former case, it is preferable to use a novolac-type epoxy resin 
represented by the formula (I) together with a compound represented by the 
formula (II) and, in the latter case, the desired effects can be obtained 
by using 3-dibutylamino-6-methyl-7-phenylaminofluoran as the basic 
chromogenic material.

Patent EP-0401152-A3 (EP)
IPC: F02C9/28
Filed: 1990-05-30
Abstract: A control to control the acceleration mode for a gas 
turbine engine so as to allow the engine to accelerate 
rapidly with adequate stall margin by simulating a compres­
sor stall limit. The stall limit is attained by generating 
a limiting ratio of burner pressure and another engine 
pressure as a function of corrected compressor rotor speed 
assuming that the stall margin is independent of compres­
sor bleed, power extraction and degradation of engine effi­
ciency. Control logic means to compensate for fan bypass 
duct pressure losses in a system that controls the accele­
ration mode for a twin spool gas turbine engine so as to 
allow the engine to accelerate rapidly with adequate stall 
margin by simulating a compressor stall limit. The stall 
limit is attained by generating a limiting ratio of bur­
ner pressure and another engine pressure as a function of 
corrected compressor rotor speed assuming that the stall 
margin is independent of compressor bleed, power extraction 
and degradation of engine efficiency. Compensation is by 
generating an engine pressure ratio signal as a function 
of corrected low pressure compressor rotor speed and 
using the difference between the signal and actual engine 
pressure ratio for modifying the simulated compressor 
stall limit.

IPC: C01B7/03
Filed: 1991-07-15
Abstract: In a continuous process for the preparation of phosphorous acid with simultaneous production of hydrochloric acid, a reaction zone is provided which is in open communication with a first scrubbing zone. A portion of the reaction product is recycled from the bottom of the reaction zone into the top of the scrubbing zone and phosphorous acid is removed from the circulation. Hydrogen chloride gas escaping from the top of the first scrubbing zone is brought into contact, in a cooled, second scrubbing zone, with an overstoichiometric amount of water. Hydrochloric acid is obtained which is passed as starting material into the reaction zone or into the top of the first scrubbing zone. The external cooling of the second scrubbing zone is controlled such that the temperature in the reaction zone is kept constant at a desired value between 90 DEG  and 130 DEG  C. without adding any external cooling or heating energy. Pure hydrochloric acid is recovered in an absorption zone.

Inventor: ZORIAN YERVANT
IPC: G01R31/3183
Filed: 1994-02-23
Abstract: The present invention is directed to a method for detecting retention faults in each of a plurality of read/write memory elements (121-12z), arranged in a plurality of banks (141-14k) coupled in daisy chain fashion. Retention faults are detected, in accordance with the method, by signaling the banks in sequence, at each of three separate intervals, to cause the memory elements in each bank to execute a first, second and third sequence of read and/or write instructions. Execution of the second sequence of read and/or write operations is delayed so each memory element can be read after a prescribed interval to detect a first bit pattern written in each memory at the end of the first sequence. Similarly, execution of the third sequence of read and/or write operations is delayed so each memory element can be read after a prescribed interval to detect a second bit, complementary to the first pattern, written in the memory element at the end of the second sequence. By delaying the execution of the second and third sequences of read and/or write operations, retention faults, if any, can manifest themselves. <IMAGE>

IPC: H04N19/895
Filed: 1992-11-27
Abstract: In a motion picture data decoding system, even if a transmission error 
including an uncorrectable code error is generated, a lacked portion of the picture can 
be corrected to be smooth with respect to a peripheral picture.  
     A block including an uncorrectable code error is generated is replaced with a 
block picture, which is produced by a past motion vector depending on a past frame 
picture. Thereby, the lack portion due to the code error can be corrected to be smooth 
with respect to the peripheral picture, regardless of the existence of the motion of the 
picture to be decoded.  
     When an uncorrectable code error is detected (S23), it is determined whether 
or not a motion quantity of a motion vector corresponding to picture data, which causes 
an error detection signal, is larger than a predetermined value. If the motion quantity is 
large, the picture data and the interpolation data are combined together. If the motion 
quantity is small, the picture data and the predictive picture data are combined together. 
Thereby, the lack due to the code error can be corrected to be unnoticeable, regardless 
of the motion quantity of the motion picture data to decoded.
Patent EP-0781904-A3 (EP)
IPC: F16D35/02
Filed: 1996-08-23
Abstract: A method and a system of controlling a viscous fluid coupling (15) in 
which, when the vehicle engine (E) is operating at low speeds, if the 
speed of rotation (SF) of the fan exceeds a predetermined speed limit 
(L3), the input signal (29) to the coupling is modified to move the 
valve member (49) toward a closed position (FIG.3A). This action reduces 
the occurrence of an overfill condition, thus reducing undesired fan 
noise when the engine again accelerates. Another aspect of the invention 
is to sense the speed (SE) of the engine, and whenever the sensed speed 
(SE) is high enough that operation in an excess slip heat region (ESH) 
is possible, compare the demanded fan speed (29) to the lower limit 
(CHP) of the slip heat region. Whenever the demanded fan speed exceeds 
the limit, the input signal (29) to the coupling is modified to operate 
the coupling at a speed safely above or below the slip heat region (ESH) 
depending on the state of control inputs such as engine temperature.
