Abstract: Digester systems for producing paper pulp from comminuted cellulosic fibrous material take into account the level of dissolved
organic materials (DOM), such as lignin, hemi-cellulose, and cellulose, maintaining the DOM level at about 100 g/l throughout the cook
(particularly kraft cook). In order to make sure there is sufficient liquid to slurry the material in the feed system of a two vessel system,
some liquid is withdrawn from the circulation conduits between the digester and impregnation vessel, cooled, and fed to the feed system.
In a vapor phase digester, the level of liquid at the top of the digester is more precisely controlled by circulating some of the withdrawn
liquid from a circulatory loop of the digester to the level tank associated with the feed system. An in-line drainer may be provided in the
feed system between a make-up liquor pump and a liquid inlet conduit leading to the top of an impregnation vessel. Within the digester, a
set of extraction/dilution screens is provided specifically positioned and spaced from each other, and with respect to a reintroduction conduit
opening, so that mixing of different DOM concentration liquids is minimized.

Abstract: A magnetic recording/reproduction apparatus is provided
which is designed to record and reproduce digital information
signals on and from a magnetic tape at a reduced error rate in a long
play mode. When the long play mode is entered, the travel speed of
the magnetic tape is changed to 1/(2n) (n = a natural number) times
that in a normal play mode, and the rotational speed of a rotary
drum is changed to (2n + 1) / (2n) times that in the normal play
mode. Tracks are written on the magnetic tape with alternate
helical scans of a pair of rotary heads, one every (2n + 1) / 2
rotations of the rotary drum to record the digital information signals
on the tracks. In an alternative form of the invention, digital
information signals are recorded on the magnetic tape in the long
play mode using a third rotary head and one of the pair of the rotary
heads. The third rotary head is mounted on the rotary drum at a
given angular interval away from the one of the pair of the rotary
heads in a height relation which allows tracks to be written on the
magnetic tape in the long play mode at the same track pitch as that
in the normal play mode.

Abstract: It is the object of the invention to provide a sub-carrier
multiplexed optical signal transmission system employing super
wide-band frequency modulation scheme, in which the SNR of a sub-carrier
of a higher sub-carrier frequency is not decreased. The
intensity of a sub-carrier of a higher sub-carrier frequency is
increased by a pre-emphasizer, and modulated in a FM modulator.
Then, a super wide-band FM signal is obtained. The super wide-band
FM signal is supplied to the transmitter laser diode, and
intensely modulate it to obtain an optical signal. The optical
signal is transmitted through an optical fiber, supplied to an
optical receiver and converted into an electrical signal. The
super wide-band FM signal thus obtained is demodulated by a FM
demodulator. The sub-carrier multiplexed signal is supplied to
a de-emphasizer having an inverse characteristic of that of the
pre-emphasizer, where the signal supplied thereto recovers its
original frequency spectrum.

Abstract: A speech encoding method and apparatus and an audio signal encoding method and apparatus in which the processing volume in calculating a weight value for perceptually weighted vector quantization may be decreased to speed up the processing or to relieve the load on hardware. To this end, an inverted LPC filter 111 finds LPC (linear prediction coding) residuals of an input speech signal which are processed with sinusoidal analysis encoding by a sinusoidal analysis encoding unit 114. The resulting parameters are processed by a vector quantizer 116 with perceptually weighted vector quantization. For this perceptually weighted vector quantization, the weight value is calculated based on results of orthogonal transform of parameters derived from the impulse response of the transfer function of the weight.

Abstract: A method and apparatus for recognizing an identifier entered by a user. A
caller enters a predetermined identifier through a voice input device (15) or a touch-tone
keypad of a telephone handset. A signal representing the entered identifier is
transmitted to a remote recognizer (30), which responds to the identifier signal by
producing a recognized output intended to match the entered identifier. The present
invention compares this recognized identifier with a list (35) of valid reference identifiers
to determine which one of these reference identifiers most likely matches the entered
identifier. In performing this determination, the present invention employs a
confusion matrix (45), which is an arrangement of probabilities that indicate the likelihood
that a given character in a particular character position of the reference identifier
would be recognized by the recognizer as a character in the corresponding character
position of the recognized identifier. This determination yields an identifier
recognition probability for every reference identifier, and the present invention selects
the reference identifier with the highest identifier recognition probability as most
likely corresponding to the entered identifier.

priority level on said shared resource, a total effective bandwidth is generated which
is represented by a sum of individual effective bandwidths of previously admitted
requests for service. Subsequent to receiving a new request for service having a
specified priority of service level, a plurality of effective bandwidths are accessed
for the new request. The plurality of effective bandwidths are respectively associated
with the specified service priority level and service priority levels therebelow. The
new request is admitted if, for the specified service priority level and for each
service priority level therebelow, the sum of (i) said total effective bandwidth for a
given service priority level and (ii) for said new request, the effective bandwidth at
the given service priority is less than the capacity.
