摘要： PURPOSE:To improve the reliability in flow-rate control by forming a plurality of flow passages each equipped with an ON/OFF valve and having different flow-rate between a pump and a hydraulic actuator and operating said ON/OFF valves by means of a computer on the basis of the information from an input part. CONSTITUTION:Four flow passages R1-R4 each equipped with each solenoid ON/OFF valve V1-V4 are installed in parallel between a hydraulic pump P for a hydraulic cylinder 1 installed onto each apparatus and a control valve CV which can be freely switched between driving in normal and reverse directions and stop. The flow-rate ratio 1:2:4:8 between flour flow passages R1-R4 is obtained by arranging the first distribution valve 2 which quantitatively distributes the oil from the pump P in the flow-rate ratio 1:4 into the first branched passage R5 and the second branched passage R6, and by arranging the second and the third distribution valves 3 and 4 for quantitatively distributing the oil from the first and the second branched passages R5 and R6 in the flow-rate ratio 1:2 into the flow passages described the above R1, R2 or R3, R4. ON/ OFF valves V1-V4 are operated by a computer 6 on the basis of the information from a flow-rate instructing input part 5.

摘要： PURPOSE:To improve the response of an actuator to prevent occurrence of hunting or chattering by connecting a return flow passage from a double-acting fluid pressure actuator to the suction passage of a pump. CONSTITUTION:A throttle valve 4 for throttling a fluid from a tank T is provided in a suction passage 3 of a pump P for supplying the fluid to a three- position type operating valve 2 for switching a double-acting type fluid pressure cylinder 1. In a case of elongating the cylinder 1, the entire quantity of a fluid of a rod side chamber 1a is supplied to a bottom side chamber 1b and the fluid is supplemented thereto from the tank T through a throttle valve 4. In a case of shrinking the cylinder 1, a lrger part of the fluid in the bottom side chamber 1b is supplied to the rod side chamber 1a and the remainder is sent from a relief passage 8 to the tank T.

摘要： PURPOSE:To improve the response of the titled actuator by connecting in parallel two operating valves to a double-acting fluid-pressure actuator and lapping in time series a part of the operations of both operating valves. CONSTITUTION:A first operating valve 2 for switching a state of driving a cylinder 1 in the normal direction to a state of stopping the same and vice versa and a second operating valve 3 or switching a state of driving the cylinder 1 in the reverse direction to a state of stopping the same and vice verse, are interposed in parallel between the cylinder 1, a pump P and a tank T. When the closing operation of one of the operating valve 2 or 3 and the subsequent opening operation of other valve 3 or 2 are lapped by a time DELTAf, the flow quantity of the fluid at the operating valve 3 or 2 which is subjected to opening operation, rapidly increases substantially coincidently to a time point where the flow quantity of the operating valve 3 or 2 to be subjected to the opening operation. has rapidly decreased.

摘要： PURPOSE:To make the operation by an unskilled operator easy, by arranging keys inputting at least Kana(Japanese syllabary) characters in the order of Japanese syllabary in a matrix shape and converting a key input signal into a standardized key code. CONSTITUTION:Keys of a key input device 2 are formed with 5-stage matrixes, the keys are arranged in 4 stages for numerals, alphabets and symbols in accordance with the JIS standards or the ASCII standards, and Kana characters are arranged as back symbols in the order of Japanese syllabary from right. In depressing a desired Kana key after depressing a Kana shift key, a code outputted from the depressed key is read with a keyboard encoder 12, code-converted 22 and inputted to an information processor 3 via an interface 13. Thus, the operation other than a professional operator can be made easy. In connecting the standardized board for specialists in parallel with the information processor 3, the processor can be used with unskilled operator and the specialist.
