Patent number: 4833714Abstract: A word speech recognition apparatus recognizes a speech inputted to a microphone (11). A feature extracting portion (20) extracts a feature parameter based on a aural signal waveform outputted from the microphone. The feature extracting circuit comprises a pitch cycle extraction circuit (21) for extracting pitch frequency of the speech signal waveform, a digital filter (23) for extracting, as a feature parameter, spectrum data of the speech signal waveform, and a filter coefficient setting circuit (22) for setting a filter coefficient so that a resonance frequency of the digital filter is an integral multiple of the pitch frequency. The feature parameter extracted from the feature extracting circuit is stored in an input pattern memory (3). A recognition processing portion (50) evaluates similarity between the feature parameter stored in advance in a registration pattern memory (4) and the feature parameter stored in the input pattern memory, so that speech recognition processing is made.Type: GrantFiled: August 4, 1988Date of Patent: May 23, 1989Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Mitsuo Shimotani, Masahiro Hibino, Kenji Shima

Patent number: 4815133Abstract: A sound field producing apparatus operatively connected to a stereophonic sound source and adapted to supply audio signals to a loudspeaker system, comprising an indirect sound extracting circuit for extracting indirect sound components by extracting a difference signal representing the difference between right and left input signals. The difference signal is phase-inverted to obtain an inverted difference signal. Two mixing circuits are provided for mixing the right and left input signal, the difference signal and the inverted difference signal to supply mixed signals. Loudspeakers are disposed on the right and left both in front of and to the rear of a listener and are driven by the mixed signals from the mixing circuits.Type: GrantFiled: February 4, 1987Date of Patent: March 21, 1989Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Masahiro Hibino

Patent number: 4484497Abstract: An engine is coupled to an automatic power transmission having a lockup device. The lockup device is in an operative position when the speed of the engine is higher than a preset lockup reference level, and is in a rest position when the engine speed is not higher than the lockup reference level. A deceleration sensor detects when the engine is required to decelerate. A speed sensor detects the speed of the engine. A fuel-control device is associated with the deceleration sensor and the speed sensor to supply fuel to the engine when the engine is required to decelerate and the engine speed is lower than an adjustable fuel-supply control level. The fuel-control device also serves to interrupt the supply of fuel to the engine when the engine is required to decelerate and the engine speed is not lower than the fuel-supply control level. When the lockup device is in the rest position, the fuel-supply control level is equal to a first preset value.Type: GrantFiled: October 12, 1983Date of Patent: November 27, 1984Assignee: Nissan Motor Company, LimitedInventor: Masahiro Hibino
