Abstract: A speech coding and speech recognition apparatus.   The value of at least one feature of an utterance is measured over each of a series of successive time intervals to produce  a  series  of  feature  vector  signals. The closeness of the feature value of each feature vector signal  to  the  parameter  value  of  each  of  a  set  of prototype  vector  signals  is  determined  to  obtain prototype match scores for each vector signal and each prototype vector signal.  For each feature vector signal, first-rank and second-rank scores are associated with the prototype vector signals having the best and second best prototype match scores,  respectively.  For each feature vector signal, at least the identification value and the rank  score  of  the  first-ranked  and  second-ranked prototype vector signals are output as a coded utterance representation signal of the feature vector signal,  to produce  a  series  of  coded  utterance  representation signals.  For each of  a plurality of  speech units,  a probabilistic model has a plurality of model outputs, and output probabilities for each model output.  Each model output comprises the identification value of a prototype vector and a rank score.  For each speech unit,  a match score comprises an estimate of the probability that the probabilistic model of the speech unit would output a series  of  model  outputs  matching  a  reference  series comprising the identification value and rank score of at least  one prototype vector  from  each coded utterance representation signal in the series of coded utterance representation signals.

IPC: H04Q3/545
Filed: 1992-09-17
Abstract: In a load control system having n types of processes provided for processing requests of an identical type, a load processing unit executes one of m types of processes among the n types of processes in response to one of the processing requests where n and m are respectively integers equal to or larger than 1 and m is equal to or smaller than n.  A monitor unit periodically monitors a load of the load processing unit and selects the m types of processes from among the n types of processes on the basis of the load of the load processing unit.  An execution ratio calculation unit determines execution ratios of the m types of processes so that the load of the load processing unit is equal to or lower than a first reference value and an execution ratio of at least one of the types of processes is equal to or higher than a second reference value.  The load processing unit executes the m types of processes in response to the processing requests with the execution ratios of the m types of processes.

Title: Monitoring of gas dissolved in oil
Inventor: SPICAR ERICH
IPC: G01N27/18
Filed: 1992-09-24
Abstract: ABSTRACT            The invention relates to a method and a device for con-tinuous monitoring of gas dissolved in oil and comprises placing a separator cell (1) in a conduit which extends from the upper part of an oil-cooled transformer and which is connected to the lower part of the transformer tank. The interior of the separator cell is divided by means of an inner glass filter (3) into two parts and the oil which flows through the separator and the glass filter is collec-ted in the lower part of the separator. Through a pump (10) connected in the conduit from the separator to the lower part of the transformer tank, the oil level of the collected oil is maintained at a constant level. Between the glass filter and the collected oil, a gas compartment (5) is formed which contains gases, extracted from the oil, with a composition and concentrations uniquely determined by those gases dissolved within the oil. A gas sensor (6) is connec-ted between the upper and lower parts of this compartment.

Title: Process for producing streptovaricin c
Inventor: INOUE KANAME
IPC: C12P17/18
Filed: 1992-10-15
Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is a method for selecting a mutant strain belonging to the genus Streptomyces which is a hyper-producer of Streptovaricin C superior to those know heretofore. This is accomplished  by first subjecting a natural strain of Strep-tomyces spectabilis to conditions so as to isolate organisms which are streptovaricin resistant.  The streptovaricin resistant organisms thus isolated are then subjected to mutagenesis and then cultured.  The colonies which are asporogenous are in-dividually cultured in fermentation batches such that the strains take the form of pellets of varying sizes and colors.          From the batch having the most heterogeneous mixture of pellets, the smallest pellet or the pellet(s) having the deepest color (usually deep red or crimson) is isolated.  We have discovered that the strain of this pellet has a high likelihood of being a hyperproducer of streptovaricin.  The strain of this pellet may then be subjected to fermentation conditions to produce streptovaricin.  The nutrient broth containing fumaric acid or water-soluble salts thereof, and adsorbent polymer beads and the streptovaricin produced are recovered in the usual manner. In another embodiment, the fermentation may be carried out in a nutrient broth wherein fumaric acid or its water-soluble salts are deliberately excluded to achieve even higher productivity.
