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 automatically perform proper evacuating action of supporting beams in continuous high-speed work and to surely prevent damage of the beams, by rocking the supporting beams so that these are not allowed to collide against the ground in basing on the difference of inclination of a leading car and a follow-up car by means of a controlling means. CONSTITUTION:A follow-up car 2 is rollingly followed to a leading car 1 and also beams 5R, 5L projected to the sides of the follow-up car 2 are vertically rocked by actuators 4R, 4L. Further the inclination in the lateral direction of the leading car 1 is detected with an inclination sensor 6 and also an inclination sensor 10 is fitted to a mechanism for taking out the average inclination of the ground in the direction rectangular to the advancing direction of the vehicle rollingly followed to the follow-up car 2. The actuators are driven to rock the supporting beams so that these are not allowed to collide against the ground in basing on the difference of detected both inclinations by means of a controlling means. As a result, even in continuous high-speed work, the proper evacuating action of the beams can be automatically performed.

摘要： PURPOSE:To make it unnecessary to make operation to return to the origin when making the power again by detecting the position of an actuator by means of an absolute position detector and reading the signal by means of a computer. CONSTITUTION:Using an absolute encoder 2 as a position detector of a hydraulic actuator 1, the present position of the actuator is recognized by reading the absolute signal (a) from the encoder 2 by a computer 3, simultaneously the absolute signals (a), (b) from the computer 3 are converted into pulses, and consequently, a digital servo system same as a case using an incremental encoder is used in simulation. Thus, the position data do not disappear even if the power is off, and the operation to return to the origin becomes unnecessary when the power is made again, and further, control can be effected by means of a computer of small capacity.

摘要： PURPOSE:To obtain highly accurate measuring signals, in a liquid pressure engine which is used in an industrial robot and the like, by providing a magnetic rotary detector, which converts the change in the relative positions of a casing and a shaft and detects the relative rotary speed or position. CONSTITUTION:An inners surface 23a of a rotor 23 is fixed to the inner surface of a casing 4. Said inner surface 23a is a circular cylinder surface, which is deviated from the axial center of a ring shaped stator 22 (the axial center of the casing 4), which is fixed to the outer surface of a shaft 3. The facing distances between the inner surface 23a and poles 22a, 22b, 22c and 22d are changed with the rotation of the rotor 23 in a sine mode. Sine wave input signals alpha and beta, which are different in phase by 90 degrees, are inputted to primary windings 24 of the poles 22a and 22c and the poles 22b and 22d, which are different in phase by 90 degrees. The rotary speed and the rotary position of the rotor 23 are detected based on the output signal gamma from a secondary winding 26. A fine angle signal, which is obtained by dividing one rotation of the casing 4 into several hundred parts, can be obtained.

摘要： PURPOSE:To prevent a brake and a hydraulic circuit in a hydraulically running farm vehicle of two pump type from being damaged, by providing a communicating passage for connecting the discharge port of one hydraulic pump to the inlet port of the other hydraulic pump and as well a valve for setting the communicating passage into its operating state. CONSTITUTION:When mechanical braking force by mechanical brakes 11, 12 is acted to hydraulic motors 1, 5, pressurized oil discharged from the discharge port 3a of one hydraulic pump 3 is delivered to the inlet port 7b of the other hydraulic pump 7 through a first short-circuited passage 26 consisting of pipe lines 31, 34, and pressure oil discharged from the discharge port 7a of the other hydraulic pump 7 is returned to the inlet port 3b of the above-mentioned one hydraulic pump 3 through a second short-circuited passage 27 consisting of pipe lines 33, 32. Further, when the short-circuited passages 26, 27 are set into their operating states, an intake port 1a and an outlet port 5b are communicated together through the passage 26, and an intake port 5a and an outlet port 5b are communicated together through the passage 27.

摘要： PURPOSE:To lessen occupying area as well as permit free wheeling by introducing rotating torque from engine by using the casing of a liquid pressure pump as a receiving pulley and also by housing auxiliary pump in liquid pressure pump. CONSTITUTION:A stationary pump unit consisting of the cylinder block 19, provided eccentrically with the fixed main axle 13, into which the piston 18 is fitted radially, is enclosed with the both side plates 11 and 12 and casing 1 and sealed. And, oil from the suction oil path 25 is discharged to the discharge oil path 26 as a pressure oil by rotating the periphery of the casing 1 as receiving pulley. On the other hand, the pressure oil is introduced from the suction oil path 27 for free wheeling to the discharge oil path 28 by means of the fixed toothed wheel 22 and the rotary toothed wheel 23. And, the casing 1 is free-wheeled by filling the pressure oil in the casing 1 by providing throttle or switching valve to the discharge oil path 28.

摘要： PURPOSE:To continuously turn an oil pressure motor by external force after backlashing, by disposing an pilot check valve and a change-over valve so that a discharge circuit of oil returning from the oil pressure motor be formed when the oil pressure motor reverses. CONSTITUTION:When changing over a chenge-over valve 14 at a location L, an oil pressure motor 4 reverses being controlled by meter-out. When the change-over valve 14 is changed over at a neutral location C and a change-over valve 13 is changed over at a location L, the supply of compressed oil to the oil pressure motor 4 is interrupted while a pilot check valve 11 is operated, the check valve 11 is opened and a discharge circuit communicated with an oil tank 7 through the change- over valve 13 is formed. Thus, returning oil is returned to the oil tank 7 through said discharge circuit because oil returning from the oil pressure motor 4 is blocked at an end of a meter-out circuit, and the oil pressure motor 4 is turned by external force.
