Patent JP-H03179904-A (JP)
Title: Buffer amplifier
Inventor: TAKAHASHI HIDENORI
IPC: H03F1/30
Filed: 1989-12-08
Abstract: PURPOSE:To reduce power consumption and to make a buffer amplifier circuit perform an operation as a smoothing circuit by providing a means to couple the oscillation frequency voltage of an oscillation circuit as input to an amplifier circuit comprised of a first transistor, and a means to output buffer-amplified oscillation frequency voltage from a corrector of a first transistor. CONSTITUTION:An AC component included in a voltage at a voltage division point (p) is designed so as to be sufficiently attenuated, and the AC component is grounded with a bypass capacitor C7. When no AC component exists in the voltage at the voltage division point (p), no AC component other than a signal voltage applied via a capacitor C4 exists on the base of a transistor Q2, therefore, a current in which a signal current is superimposed on an AC current flows on the emitter of the transistor Q2, and such signal component is bypassed through a capacitor C5, and a DC voltage without having a noise or a ripple is supplied to the oscillation circuit. A resistor R7 is inserted so as not to ground the signal voltage from the capacitor C4 with the capacitor C7. The noise and the ripple included in a power source are attenuated with a low-pass filter comprised of a capacitor C6 and a reactor L2 and are not amplified with the transistor Q2 differently from a signal, therefore, a ratio of signal to noise can be sufficiently suppressed.

Title: Voice japanese conversion system
Inventor: TSUBOI TOSHIAKI
IPC: G10L15/18
Filed: 1989-12-08
Abstract: PURPOSE:To enable highly accurate Japanese conversion even when a composite word is inputted as it is by making the evaluated value of a candidate for a composite word consisting of plural successive word candidates larger than an evaluated value determined by word candidates included among the composite candidates when the candidate is registered in a composite word pattern table. CONSTITUTION:A voice recognition part 3 matches an input voice which is inputted from a voice input part 1 with standard patterns of syllables and words stored previously in a standard pattern storage part 2 and sends the recognition result to a word dictionary collation part 4. The word dictionary collation part 4 collates the input recognition result with a word dictionary 5 and extracts candidates of the composite word consisting of a series of word candidates and successive word candidates. A composite word pattern processing part 6 checks whether or not the composite word candidate is registered in the composite word pattern table 7 and then makes the evaluated value of the composite word candidate larger than the sum of respective evaluated values of the respective word candidates included among the composite word candidates when the composite word candidate is registered. Consequently, the input composite word can be converted into Japanese with high accuracy.
