Abstract: An ammoxidation method in a fluidized-bed reactor, in
which, when a starting material to be ammoxidized is
ammoxidized by means of vapor-phase catalytic fluidized-bed
reaction, the reaction is carried out in a fluidized-bed
reactor to which an oxygen-containing gas is fed through
feed openings provided at the bottom thereof, and a
starting material to be ammoxidized is fed through feed
openings provided above the feed openings for the
oxygen-containing gas, the distance between the feed
openings for the oxygen-containing gas and those for the
starting material being from 30 to 250% of the height of
a fluidized solid matter in a static state so as to form
such a fluidized bed that the density of the fluidized
solid matter at the feed openings for the starting material
to be ammoxidized is in the range of 50 to 300 kg/m 3  and
that the gas velocity is 1 m/s or lower. By this method,
the efficiency of contact between catalyst particles and
a starting material, and the result of the reaction (the
yield of a desired product) are improved. 
     One specific example of the present invention is a
method for ammoxidizing methanol, in which, when the
vapor-phase catalytic ammoxidation of methanol is carried
out in a fluidized-bed reactor to obtain hydrocyanic acid,
the reaction is carried out by using, as a catalyst, a
metallic oxide containing [I] at least one element selected
from the group consisting of iron, antimony, phosphorus and
copper, and [II] at least one element selected from the
group consisting of vanadium, manganese, molybdenum,
tungsten and bismuth, by feeding, to the catalyst bed, an
oxygen-containing gas through feed openings provided at the
lower part of the reactor, and methanol and ammonia as a
water-vapor-containing gas through feed openings provided
above the feed openings for the oxygen-containing gas, or
by feeding all of or a part of the water vapor to the
catalyst bed through feed openings provided below the feed
openings for methanol and ammonia, with the molar ratio of 
water vapor to methanol adjusted to 0.1 to 3. By this
method, the reaction can be efficiently carried out even
under such reaction conditions that the amount of oxygen
or ammonia relative to that of methanol contained in a feed
gas is small, and the desired product, that is, hydrocyanic
acid, can thus be obtained in high yield and also stably
with time.

Abstract: A signal processing circuit (23) converts a serial
analog signal, obtained by sequentially reading data
recorded on a disk (1) by a head (2), to a parallel digital
signal to be output. The signal processing circuit (23)
also converts an externally input parallel digital signal to
a serial analog signal at the time of recording data on the
disk (1) and sends the analog signal to the head (2). The
signal processing circuit (23) comprises a converter (31)
that converts the serial analog signal of data read from the
disk (1) to a serial digital signal and converts the
parallel digital signal of externally input data to an
analog signal in order to send the analog signal to the head
(2). A shift register (33) converts the serial digital
signal received from the converter (31) to a parallel
digital signal in a data read mode and converts the parallel
digital signal externally input to a serial digital signal
to send the serial digital signal to the converter (31) in a
data write mode. A processor (36) operates faster than a
disk access speed to perform a predetermined reading process
on the parallel digital signal received from the shift
register (33) to send out the resultant read signal and to
perform a predetermined writing process on the parallel
digital signal externally input to send the resultant write
signal to the shift register (33). A program memory (37),
connected to the processor (36), stores programs associated
with the reading process and writing process that are
performed by the processor (36).

(PT), whose measurement signal is compared with the
measurement signal of the actual value of the regulation
pressure in the regulation zone (Z1...Z24) concerned. The
result of the comparison is stored on the page of monitoring
of pressure detectors contained in the central computer
system, on which page, in addition to said difference, the
set values and actual values of the regulation zone pressures
as well as the value of the reference measurement are
given. In addition to this, a correction can be made to the
actual value of the regulation pressure in the regulation
zone (Z1...Z24) concerned if the difference between the
measurement signal of the reference pressure detector (PT)
and the measurement signal of the actual value of the
regulation pressure in the regulation zone (Z1...Z24) concerned
is higher than a pre-determined value.

Abstract: Methods for displaying results of a spreading activation algorithm and for defining an
activation input vector for the spreading activation algorithm are disclosed. A planar
disk tree is used to represent the generalized graph structure being modeled in a
spreading activation algorithm. Activation bars on some or all nodes of the planar
disk tree in the dimension perpendicular to the disk tree encode the final activation
level resulting at the end of N iterations of the spreading activation algorithm. The
number of nodes for which activation bars are displayed may be a predetermined
number, a predetermine fraction of all nodes, or a determined by a predetermined
activation level threshold. The final activation levels resulting from activation spread
through more than one flow network corresponding to the same generalized graph
are displayed as color encoded segments on the activation bars. Content, usage,
topology, or recommendation flow networks may be used for spreading activation.
The difference between spreading activation through different flow networks
corresponding to the same generalized graph may be displayed by subtracting the
resulting activation patterns from each network and displaying the difference. The
spreading activation input vector is determined by continually measuring the dwell
time that the user's cursor spends on a displayed node. Activation vectors at various
intermediate steps of the N-step spreading activation algorithm are color encoded
onto nodes of disk trees within time tubes. The activation input vector and the
activation vectors resulting from all N steps are displayed in a time tube having N+1
planar disk trees. Alternatively, a periodic subset of all N activation vectors are
displayed, or a subset showing planar disk trees representing large changes in
activation levels or phase shifts are displayed while planar disk trees representing
smaller changes in activation levels are not displayed.

Abstract: A database having fixed length records stored together in record number order and an
index structure for the database. The index structure comprises a separate index for each
searchable field of the records. For purposes of indexing, the records are logically divided into
fine slices of 8,000 records each, and the fine slices are grouped into coarse slices of 4,000 fine
slices each. The indexes include fine and coarse keys, each of which corresponds to a particular
data value and a particular fine or coarse slice. Associated with each key is a link that is used to
determine which records contain the data value. For the fine keys, the link includes a pointer to a
bit vector that has a single bit for each of the records within the fine slice associated with the key.
For the coarse keys, the link includes a pointer to a bit vector that has a single bit for each of the
fine slices contained in the coarse slice. The coarse bit vector comprises two bit vectors, one that
identifies which of the fine slices within the coarse slice contains any records having the data
value and one that identifies which fine slices, if any, contain the data value in every one of its
records. The keys are stored in a B-tree in order of a unique key value so that they are processed
in record number order and the resulting list of records for any query is generated in record
number order.
