Title: Hydraulic drive controller
Inventor: TOYOOKA TSUKASA
IPC: F15B11/00
Filed: 1992-05-20
Abstract: PURPOSE:To eliminate the bad affect of flow force and improve pressure compensation properties. CONSTITUTION:Pressure compensation valves 6A and 6B introduce upper stream pressure PZA and PZB and maximum load pressure PLS to control the pressure difference between the pressure of the portions before and after flow control valves 4A and 4B so that they become a specified pressure difference, (PS-PLS). Although pressure compensation properties are generally deteriorated due to the flow force generated in the pressure compensation valves 6A and 6B, the pressure reduction due to flow force is compensated by providing throttles 10A and 10B and pressure controlling valves 12A and 12B and reducing the maximum load pressure introduced to the pressure compensation valves 6A and 6B by increasing the flow rate of the pressure control valves 12A and 12B as load pressure PLA and PLB become small.

Abstract: PURPOSE:To seve labor by feeding an interference signal into a sample according to a preset value thereof memorized in a memory device after the measurement of a conduction interference noise of the sample. CONSTITUTION:A CPU 12 connects a power source 4 to a dummy load 9 by driving a switch 18 and sends an instruction to a signal generator 1 to set the interference signal level and the frequency. Then, when an instruction is provided to the signal generator 1 to feed an interference signal into a cable 5 and a transformer 2, it overlaps the cable 5 and is detected with a current probe 16. Then, the CPU 12 provides an instruction to an interference level meter 6 to measure the interference signal level which will be taken thereinto 12. Subsequently, it is determined whether the interference signal level data is within the allowable errors and the sequence is repeated until it becomes so. Then, it is determined whether the sequence covers the entire frequency range and the output values of the interference signal are memorized into a memory device 11 over the entire frequency range. Then, the CPU 12 provides a drive signal to the switch 18 to connect the power source 4 to a sample 3 and the output values of the interference signal are taken out of the memory device 11 to set the interference signal and the frequency. Then, with a decision made on the end of the test, the interference signal is applied to the sample 3 over the entire frequency range. As a result, the interference signal can be automatically obtained as specified and indicated on a diaplay 14. Thus, saving of labor and accurate operation are accomplished.
