Title: Voice recognizing system
Inventor: ERUNSUTO BUNGE
IPC: G10L15/00
Filed: 1976-08-13
Abstract: Sounds or speech signals are converted into an electrical sound and broken down into separate spectral components in a filter bank. These components are integrated over a short period of time and produce a short-time spectrum of the signal. The spectal components are applied, via a corresponding number of parallel leads, to a number of pattern detectors which supply an output signal only if the short-time spectrum corresponds to the pattern adjusted in the relevant pattern detector. To this end, each pattern detector includes two threshold value (window) detectors which supply a signal if the applied input signal lies between two adjustable thresholds. Each threshold value detector is connected to a different output of the filter bank for another spectral range and is generally adjusted to different threshold values. The outputs of the threshold value detectors are combined via an AND-element, so that a signal is produced only if all threshold value detectors of the pattern detector are activated. For each sound or for each phoneme in the case of speech, a pattern detector is provided. When series of sounds or signals are recognized, the series of addresses of the pattern detectors which have successively generated an output signal are stored and subsequently applied to the computer for comparison.

Then it is decided whether the initialization is through in a normal or abnormal state. Then the controller 4 executes an interruption request to the channel 1. A channel interface 6 receives the selection signal delivered from the channel 1 in response to said interruption request. Then the controller 4 displays the state information and transfers it to the channel 1.

Title: Manufacture of nonvolatile semiconductor memory
IPC: H01L29/792
Filed: 1992-03-24
Abstract: PURPOSE:To integrate the title memory at high productivity by a method wherein a lithographic process is performed only once even when control gates and floating gates having narrow line-and-space are formed. CONSTITUTION:A photoresist 21 which is to be used as an etching mask is exposed via a light-transmitting member 22. The phase of light which has been transmitted through a glass substrate 23 and a line part 24 is shifted with reference to light which has been transmitted through the glass substrate 23 and an interval part 25. Due to the interference of light near the boundary between the line part 24 and the interval part 25, the intensity of transmitted light is low near the boundary, and two pairs of exposed parts and non-exposed parts can be formed with reference to one pair of the line part 24 and the interval part 25.

Title: Control device for synchronous motor
Inventor: NASHIKI MASAYUKI
IPC: H02P25/098
Filed: 1994-05-11
Abstract: PURPOSE:To make possible the high speed rotation of a motor even when its number of rotations is exceeded and prevent unnecessary exciting current components from being passed in case motor current is increased, by creating a relative phase angle of the rotor relative to motor current so that the magnetic flux within the motor will be made proper. CONSTITUTION:A relative phase angle creating means 9 creates a relative phase angle A to reduce exciting current components in proportion to I/SD with the increase in number of rotations SD. The relative phase angle creating means thereby reduces the exciting current component of a motor to a specified value or below when its base number of rotations is not reached, and keeps the counter electromotive force of the motor almost constant when the base number of rotations is exceeded. A current amplitude commanding means 8 is fed with torque command T and outputs current amplitude command IOS. As a result, the relative phase angle of the rotor relative to motor current is reduced and thus high speed rotation is feasible when the base number of rotations of the motor is exceeded. In addition, relative phase angle is reduced and thus the passage of an unnecessary exciting current component is prevented when motor current is in proximity to or above the rated value.
