Title: Speed control circuit for dc motor
Inventor: ISHII HIDEKAZU
IPC: H02P7/288
Filed: 1989-09-22
Abstract: PURPOSE:To improve control characteristic by arranging first and second reference voltage sources, respectively, between the non-inverted input terminal and a terminal and between the inverted input terminal and a terminal of an operational amplifier. CONSTITUTION:An operational amplifier OP operates at all times such that the voltage at the inverted input terminal is equal to the voltage at the non- inverted input terminal and thereby the inverted and non-inverted input terminals can be considered apparently short-circuited (imaginary short circuit). Consequently, the sum of the voltage VR1 of first reference voltage source 6 and the voltage VR2 of second reference voltage source is produced between the terminals 3, 4 and considered to be the reference voltage VR generated in a circuit IC-1. Consequently, VR=VR+VR2 is satisfied and the voltage V across the constant current bias source Io of the operational amplifier OP can be shown by the formula on the drawing. When VR1, VR2 are set at 0.2V, voltage of 0.3V can be obtained across the bias source Io of a differential amplifier even if the voltage VR between the terminals 3, 4 is 0.4V.

Inventor: SHIGA YOSHINORI
IPC: G06F17/27
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To generate smooth pitch patterns without performing a wasteful point pitch setting. SOLUTION: A morpheme analysis is conducted against an inputted KANJI (Chinese characters) and KANA (Japanese alphabets) mixed sentence in a language analysis processing section 11 and reading and accent information is generated. In a voice synthesis section 2, a phoneme continuation time computation processing section 21 decides the phoneme continuation time based on the reading information. An every phoneme point pitch setting processing section 22 sets point pitch positions at one or two points in four equally divided continuation time of each phoneme based on the accent information and the height of the pitch is set at that location. The setting time of the point pitch and the frequency are decided by the phoneme position which sets the accent type and the pitch and the kind of the phoneme or phoneme environment.  The obtained phoneme information, the phoneme continuation time and the point pitch setting position are written into a file 31 as a voice symbol column by a voice symbol column generation processing section 23. Then, the pitch pattern of the voice to be synthesized based on the phoneme continuation time of the voice symbol column and the point pitch position and phoneme parameters are generated based on the phoneme information and finally a voice is synthesized.
