摘要： PURPOSE:To improve the responsibility and minute flow rate controllability of a servo valve by inserting valve members which are connected with the first and the second rotary driving body, and establish valve openings according to the relative rotating angles of both the said rotary driving bodies in a valve main body. CONSTITUTION:A valve member 1 which is connected with the first and the second motor M1, M2, and establishes a valve opening communicating with load ports C1-C4 according to the relative rotating angles of the said motors is inserted in a valve main body 3. Since the said relative rotating angles can be therefore controlled by adjusting the rotating angle of the said motors, the valve opening can be extremely smoothly and quickly adjusted to improve the responsibility of the valve. In addition to that, since the relative rotating angle is controlled by means of a time function, infinitesimally divided time in the said function can make the control of a minute flow rate possible.

摘要： PURPOSE:To steeply reduce the axial size of a whole device by fixing a flexible spline to a housing so as to extract the rotating power from a ring-like circular spline. CONSTITUTION:This prime mover outputs the power for a liquid-operated motor 1 via a harmonic reduction gear 2. The liquid-operated motor 1 has a support shaft 3 with an eccentric section 3a and a casing rotatable around the axis center O1 of this support shaft 3. A ring-like circular spline 22 is rotatably supported on the inner circumference of a cup-like housing, and a wave generator 25 is arranged inside this circular spline. The flexible spline 24 of the harmonic reduction gear 2 is fixed to the housing holding the support shaft of the motor 1 and extracts the rotating power from the circular spline 22.

摘要： PURPOSE:To increase positioning accuracy by detecting a differential pressure between the positions before and aft of the hydraulic oil passing through a liquid-operated motor and by compensating output value of the liquid-operated motor using the detected value of the differential pressure. CONSTITUTION:A rotational position of a liquid-operated motor 1 is detected by a rotational position sensor 41, while a feedback control is performed on the basis of the detected value, and simultaneously, a differential pressure between the positions before and aft of the hydraulic oil passing through the liquid- operated motor 1 is detected by a pressure sensor 43 as a physical phenomenon proportional to a deflection of the transmission mechanism such as a harmonic reducer 2, etc., and the output value corresponding to the rotational position of the output shaft of a hydraulic actuator P is compensated using the above detected value. Thus, it is unnecessary to use any expensive rotational position sensor of extremely high resolution and further, high positioning accuracy is assured even if a load varies.

摘要： PURPOSE:To obtain an apparatus free from positional deviation, by generating an increment pulse or a decrement pulse depending on the comparison of absolute data for sending them to a counter. CONSTITUTION:When a command pulse is inputted into an increment/decrement counter 1, an actuator 4 is rotated according to a deviation data outputted from the counter 1. The absolute position of the actuator 4 is detected with an absolute encoder 5 and sent to a comparator circuit 7 through a latch circuit 6. The comparator 7 compares the output (a) of the latch circuit 6 with the count data outputs (b) of an increment/decrement counter 11. It is so arranged that a gate synchronization circuit 10 controls to send an increment pulse (h) or a decrement pulse (g) to the counter 11 and the counter 1 until both values equal. Then, the count output data of the counter 11 is outputted as absolute data.

摘要： PURPOSE:To attain the highly accurate speed/position control of a hydraulic actuator by detecting the shift speed and the acceleration to estimate the overrun amount of the stop control and changing one side of the positioning target value, etc. in response to the estimated overrun amount to perform the compensation of data. CONSTITUTION:A proportion control valve 20 is controlled via an amplifier 19 by a speed command given from a control unit 14. Then a hydraulic actuator 1 is driven. The set values of the position, the speed and the stop position respectively are supplied to the unit 14 from a sequence control circuit 21 via each setting units 18, 17 and 13. At the same time, the pressure 3 and the position 2 applied to the actuator 1 are also detected and supplied in the same way via a compensation arithmetic circuit 12, etc. Here an overrun estimating means 7 including an overrun amount arithmetic circuit 11, etc. Then an estimated overrun amount OVR is decided by the detected speed data Dv, the acceleration data Dx and the load condition detecting data Dp. Based on the amount OVR, the data Dx is equal to the value Dxo which is compensated with increase and decrease through the circuit 12. Then the value Dxo is compared 15 with the target value data Sx.
