Abstract: PURPOSE:To adopt the constitution using one modulator so as to obtain a modulation output with dither surely eliminated therefrom and to facilitate circuit integration by providing an adder means adding an output of a delay means and a direct signal from a modulation means. CONSTITUTION:A delay circuit 14 retards an output from a DELTA-SIGMA modulator 13 by a period corresponding to nearly 1/2 of a signal period in a dither signal 19a by using the same clock signal 18a as that for the DELTA-SIGMA modulator 13 and a dither generator 19.

Filed: 1993-05-19
Abstract: PURPOSE:To improve the precision and the response speed by using a position or speed control actuator using an electroviscous fluid with which the shearing stress is proportional to the shearing speed in a voltage application state. CONSTITUTION:An electroviscous fluid 23 is enclosed in a parallel and fixed gap formed between a pair of electrode plats 24, and the voltage is applied to the fluid 23 from a power supply 29. The rough and high speed drive of a robot arm 20 is carried out by a motor 17 based on the signal which is fed back to the motor 17 from an angle sensor attached to the motor 17, however, no voltage is applied to the fluid 23. The voltage is applied to the fluid 23 in a low speed driving mode where a prescribed speed and the prescribed positioning accuracy are required, and the motor 17 is controlled by a position sensor 28 and the angle sensor. Therefore, a control system is easily stabilized and the highly precesion positioning control is ensured owing to a fact that the shearing stress is nearly linear to the shearing speed with an electroviscous fluid that shows a Newton fluid type Viscous behavior.

Abstract: PURPOSE:To eliminate the use of any externally mounted capacitor and to attain high circuit integration by utilizing the maintenance of the on-state for a prescribed time of a transistor (TR) because of a charging potential of a capacitance between base and emitter and between base and collector of the TR. CONSTITUTION:When an input signal phi0 of a waveform shaping circuit 14 rises to a level 1, a TRQ0 is turned on, a potential phi1 of a node N1 goes to level 0 and TRs Q1, Q3 are turned off and a potential phi2 of node N2 rises to level 1. Thus, TRs Q2, Q6 are turned on, a potential phi3 of a node N3 decreases to level 0, a TRQ8 is turned off and an output signal phi5 increases to level 1. In this case the capacitance between the base and emitter and between the base and collector of the TRQ4 is charged. Even if the TRQ3 is turned off, the on-state of a TRQ7 is kept by the charging potential of the capacitance between the base and emitter and between the base and collector of a TRQ5, the TRQ7 is turned off after a prescribed time, a potential phi4 of the node N4 goes to level 1, causing the TRQ9 to be turned on and the signal phi5 to go to level 0, then a differentiating pulse is generated.
