Title: Bus driving circuit
Inventor: TSUDA TOSHITAKA
IPC: H03K17/64
Filed: 1983-12-08
Abstract: PURPOSE:To supply a fixed amplitude voltage to a bus driving circuit by connecting respective emitters of TRs constituting differential pairs each other through the primary winding of a transformer and providing the bases of both the TRs with a potential difference required for the primary side of the transformer. CONSTITUTION:When a signal S1 larger than a reference voltage Vref2 is applied to the base of a TR10, the TRs 10, 5 are turned on and the voltage VB of the TR1 is dropped. Current flows into a diode D1 and a current source TR3 is turned on. When a signal S2 larger than the reference voltage is applied to the base of a TR9, both the TRs 9, 6 are turned on, the voltage VB of the TR4 is dropped, current flows into a diode D2, and a current source TR4 is turned on. Current I1 is the sum of current I3 and I4 of the differential pairs TR1, 2 and the ratio is fixed by the ratio of the voltages VBE of the TRs 1, 2. Even if buses are simultaneously driven and a potential difference is generated on the primary side of the transformer by forming plural driving circuits shown in the figure and connecting the secondary sides of the transformers T in series, a signal with a fixed amplitude is outputted because the differential pairs distribute current.

IPC: H02P27/08
Filed: 1985-10-17
Abstract: PURPOSE:To maintain armature currents in the form of sine waves, and to reduce vibrations and noises by limiting a current command value in response to an input to an integrator. CONSTITUTION:An input to a integrator (b) is subject to the influence of the saturation of a drive circuit for a motor when the drive circuit is saturated, and the input to the integrator (b) is slight when the drive circuit is not saturated. The input to the integrator (b) is applied to a function generator (e) responding to the variation of the input to the integrator, aiming at the variation of the input to the integrator. An output signal from the function generator (e) is transmitted over a current limiting circuit (h) through an absolute value circuit f and polarity clamps g1, g2, and a current command value is reduced. That is, a saturating current command is changed continuously by an output from the function generator (e), and an output signal from the drive circuit, armature currents, are maintained in the form of sine waves.

Filed: 1987-09-18
Abstract: PURPOSE: To double the performance of compression without changing a conventional encoding part by compressing a useless part (the repeated part of approximately the same waveform in silence or a voiced sound) in a voice. CONSTITUTION: When the contents of a recording buffer memory 2 are data indicating silence, code data are not written in a memory 7 and the data length of silence is recorded in a synthesis control memory 4. At the time of inputting a voiced sound, the similarity of stored data between buffers is judged so that data for one pitch are stored in one buffer, only representative data are stored in the memory 7, the other buffer data are not stored and only the number of buffers having similar data is stored. At the time of reproducing data, code data for specified data length are read out from the memory 7 in accordance with information read out from the memory 4 and sent to a decoder 9 repeatedly by the specified number of times. Consequently, an inputted voice is recorded by a compression rate extremely larger than the compression rate of a conventional encoder.
