Patent EP-0334580-A3 (EP)
IPC: H04N5/945
Filed: 1989-03-20
Abstract: A system and method for performing error 
correction on an SFAT format video signal which has 
been encoded using an error correction code ECC2, and 
generating a video signal reconstructed from the error-­
corrected input signal. The error code preferably is a 
cross interleave Reed-Solomon code. In a preferred 
embodiment, the system is capable of reconstructing the 
output video signal so that it has either SFA or SFAT 
format. Since an SFAT signal includes duobinary encoded 
data in its active video areas, and thus may be doubly 
error encoded using two error correction codes (ECC1 and 
ECC2), the invention is capable of generating from such 
a doubly encoded signal an ECC1 error-encoded video 
signal, in SFA (or SFAT) format, which has been error-­
corrected using error code ECC2. This capability is 
particularly advantageous where the invention is 
embodied in a video disk mastering system or method. In 
a preferred embodiment, the invention also determines 
the error rate of the input signal and generates a 
report signal indicative of the input signal's detected 
error rate. A preferred embodiment of the invention 
performs both error correction and error detection on-­
line, in real time, and automatically.

Title: Method for determining susceptibility of an organism to a potentially toxic agent
IPC: G01N33/50
Filed: 1989-06-23
Abstract: A method for determining the susceptibility 
of an organism to a potentially toxic agent comprising: 
(i) providing a control sample and a treatment sample 
from cells derived from the organism; (ii) contacting 
the treatment sample with the potentially toxic agent; 
(iii) incubating the cells of the treatment and control 
samples after step (ii), in nutrient medium and then 
assaying the apparent number of intact cells; and, (iv) 
determining a measure of susceptibility of the organism 
to the potentially toxic agent from a comparison of the 
change in number of apparently intact cells in the 
control and treatment samples over time. This method 
can be used to assess the therapeutic regime to give 
maximum benefit with minimum risk. It can be also used 
to test applicants for employment where there is an 
occupational hazard associated with genetoxic agents.

Title: Papermaking filler compositions
IPC: D21H17/37
Filed: 1989-09-19
Abstract: A composition for flocculating paper- or boardmaking 
filler comprises particles of starch, in aqueous 
suspension, and a flocculating agent, eg. a 
polyacrylamide. Preflocculated filler for addition to a 
paper- or boardmaking stock may be prepared by adding such 
a composition to an aqueous slurry of filler particles, 
eg. calcium carbonate. The use of particulate starch that 
is insoluble in water at temperatures normally encountered 
in the wet-end of a paper- or boardmaking process, in 
particular temperatures below 35°C, obviates the need for 
a preliminary solubilisation step. However, the starch is 
soluble at temperatures encountered in the drying stage of 
the paper- or boardmaking process, where a starch solution 
is formed which is distributed through the paper matrix 
and imparts thereto additional strength.

Abstract: A magneto-optical disk comprising a substrate, a 
recording layer formed on the substrate, and a 
solid-lubricant film, whereon slides a flying-type 
magnetic head used for recording and/or reproducing, the 
solid-lubricant film being formed on the recording layer 
and being made of polyolefin containing perfluoroalkyl 
group, or of glassy carbon. Adhesion of the flying-type 
magnetic head to the surface of the magneto-optical disk

solid-lubricant film is formed by sputtering target 
material with argon ions, the target material being 
achieved by kneading polytetrafluoroethylene powder with 
perfluoropolyether. An external magnetic field of 
substantially constant intensity can be applied on the 
recording layer because the solid-lubricant film is 
substantially uniform in thickness.

Title: Resynchronisation of a superscalar processor
Inventor: WHITE SCOTT A
IPC: G06F9/38
Filed: 1995-05-30
Abstract: Operations of a pipeline processor (110) are resynchronized under designated conditions. The processor updates a fetch program counter (210) and, as directed by the counter, fetches instructions from a memory (114). The processor concurrently dispatches, in the fetched order, multiple instructions to designated functional units (170,171,172,173,174 and 175). Dispatched instructions are queued in functional unit reservation stations. Result entries corresponding to the queued instructions are allocated in a reorder buffer (126) queue in their order of dispatch. Instructions are executed out of their fetched order and results are entered in the allocated result entries when execution is complete. Allocated result entries at the head of the reorder buffer queue are retired and an instruction pointer (620) is updated. The processor is resynchronized when it detects a resynchronization condition and acknowledges the resynchronizsation condition in the allocated result entry corresponding to the instruction that detected the condition. When the reorder buffer entry holding the resynchronization acknowledgement is retired, the processor flushes the reorder buffer and the reservation stations of the functional units and redirects the fetch program counter to the instruction addressed by the instruction pointer.

Title: Recording digital video signals
Inventor: OIKAWA YUKA
IPC: H04N9/804
Filed: 1995-08-18
Abstract: In a technique for recording digital video signals, digital video signals in the form of DCT coefficients, obtained by e.g. discrete cosine transformation, are quantized and compressed so as to be recorded on a recording medium. A first quantization step decision unit (23) determines a quantization step in terms of a video segment made up of plural macro-blocks as a unit so that the quantity of quantized data is less than a pre-set data quantity. A second quantization step decision unit (24) determines a quantization step in terms of the macro-blocks as a unit so that the quantity of quantized data is less than the pre-set data quantity. A quantization unit (25) quantizes the digital video signals with quantization steps determined by the first and second quantization step decision units (23, 24). This enables efficient encoding and improved picture quality. <MATH>
