Patent EP-0781034-A3 (EP)
Inventor: KABURAGI HIROSHI
IPC: H04N1/41
Filed: 1996-12-20
Abstract: Upon gradation converting input m-bit image
information into n-bit image information (m and n are
integers; m > n), random numbers, the maximum values of
which are changed in accordance with the input values of
the m-bit image information, are generated at periods of
two or more pixels, and the random numbers are
selectively output while switching their signs to
positive/negative within the period of two or more
pixels. The output signal values and the input values of
the m-bit image information are added to each other, and
the sum signal values are converted into n-values by a
density preservation type quantization method. With this
control, the problems of sweeping, texture, and the like
of the conventional density preservation type
quantization method can be solved without emphasizing
the granularity of an image.

Abstract: A method and apparatus for compensating for weak elements
of a dynamic memory circuit on an integrated circuit chip is
disclosed. The method includes identifying weak elements in the
memory circuit. The elements may be identified by a known test
program, and may be bits, blocks, or other portion of a dynamic
memory circuit. The locations of the identified weak elements
are programmed into a programmable memory, and the programmed
information in the programmable memory is used to refresh the
identified weak elements at a different rate from the refresh
rate of other bits. This allows an extended or longer refresh
interval to be used for the strong elements, while providing
adequate refresh for the weak elements, thereby reducing the
refresh interval required for the overall memory circuit from
the refresh interval which normally would have been used.

Abstract: A fully differential circuit in which all inputs and outputs
of transconductors Gm1+, Gm1-, Gm2+, Gm2- and fixed gain amplifier
GA are fully differential signals. The number of feedback loop
elements is made odd by the addition of a fixed gain amplifier
with a gain of 1 which is not used in conventional filter
architecture, each element of the configuration consequently
inverts the common voltage, and since the feedback loop has
negative feedback with respect to the common voltage, the
operating point can be determined without a need for a dedicated
DC feedback circuit.

Abstract: A die casting shot sleeve (20,20') has an overflow hole (28,28') and
an overflow valve (38,38') for selectively opening and closing the overflow
hole. The overflow hole extends through the shot sleeve at a level below a
pour hole (18,18') to allow molten material in excess of a predetermined

excess metal to spill from the shot sleeve. When closed, the metal can be
expelled from the sleeve without additional material spilling through the
overflow hole.

Abstract: Acetic anhydride is produced by reaction of methyl
acetate (or dimethyl ether and acetic acid), carbon
monoxide, and hydrogen in the presence of an alkyl halide
and a heterogeneous, bifunctional catalyst that contains an
insoluble polymer having pendant quaternized phosphine
groups, some of which phosphine groups are ionically bonded
to anionic Group 9 or 10 (post-1986 IUPAC-recommended
nomenclature) metal complexes, the remainder of the
phosphine groups being bonded to iodide. In contrast to
prior art processes, no accelerator (promoter) is necessary
to achieve the catalytic reaction and the products are
easily separated from the catalyst by filtration.

Abstract: A system and method for modification of the visual characteristics of digital 3D
objects includes a shading buffer wherein parameters relating to the visual characteristics of a
rendered 3D object are stored. When a texture applied to the 3D object is selected for
modification, a pre-rendering step is performed and a shading buffer constructed. The shading
buffer includes pre-computed components of the visual characteristic information for each
rendered pixel of the displayed 3D object, these components are independent of the texture
selected for modification. When the texture is modified, by indicating one or more pixels on
the 3D object to which the texture is applied, re-rendering of those pixels is accomplished by
evaluating a simple combination of the corresponding pre-computed components in the shading
buffer and the modification effected to the selected texture obtain new final values to render
the pixels. By pre-computing and arranging the components in the shading buffer, the
computational requirements for re-rendering the modified portions of the 3D object are
reduced, improving the re-rendering response of the system and method and allowing real time
re-rendering in many circumstances.

Abstract: The output from a digital signal amplitude
regenerator circuit (10, 51) in which the amplitude
of a transmitted burst data signal is amplified, and
an initial potential generator circuit (11, 52), are
connected to a switch (12, 53). While there are no
burst data, the initial potential generator circuit
(11, 52) provides a circuit for compensating for
degradation in pulse width comprising a low-pass
filter (13, 54), a pulse width compensation threshold
generator circuit (14), and a limiting amplifier (15,
58), with an initial potential needed to set a
threshold. When a carrier detection signal generator
circuit (16, 59) detects the arrival of a burst data
signal, a carrier detection signal is outputted, and
the switch (12, 53) is switched over from the initial
potential to the burst data signal. Thus, the circuit
for compensating for the degradation in pulse width
located at a later stage can detect a threshold from
an optimal initial potential, and thereby the
degradation in pulse width can be optimally 
compensated.

Abstract: A speech parameter coding method and apparatus
which can quantize a spectrum parameter of a speech
signal with a smaller number of bits than ever. A
dividing section divides a predetermined order number of
spectrum parameters, obtained by division of a speech
signal into frames, for each order number of spectrum
parameters smaller than the divisional order number. A
vector quantizing section searches codebooks for the
divided spectrum parameters for each order number and
outputs a plurality of candidates of codevector in order
of magnitude from the minimum one. An accumulated
distortion calculating section calculates accumulated
distortions for the entire order number for combinations
of codevectors. A minimum Judging section selectively
outputs a combination of codevectors which minimizes the
accumulated distortion thereby to quantize the spectrum
parameter.

Abstract: The present invention is a method and apparatus for optimizing a non-inclusive
multi-level cache memory system. Cache space is provided in a first cache by removing
a first cache content, such as a first cache line or block, from the first cache. The
removed first cache content is stored in a second cache. This is done in response to a
cache miss in the first and second caches. All cache contents that are stored in the
second cache are limited to have read-only attributes so that if any copies of the cache
contents in the second cache exist in the cache memory system, a processor or
equivalent device must seek permission to access the location in which that copy exists,
ensuring cache coherency. If the first cache content is required by a processor such as
when a cache hit occurs in the second cache for the first cache content, room is again
made available, if required, in the first cache by selecting a second cache content from
the first cache and moving it to the second cache. Once room is available in the first
cache, the first cache content is moved from the second cache to the first cache,
rendering the first cache available for write access. Limiting the second cache to read-only
access reduces the number of status bits per tag that are required to maintain cache
coherency. In a cache memory system using a MOESI protocoal, the number of status
bits per tag is reduced to a single bit for the second cache, reducing the tag overhead.
An optimization advantage in that the tags may be placed on-chip so as to improve
cache bandwidth.
