摘要： Apparatus and method for controlling equipment of driving a ram of a hydraulic press. Four proportional sheet valves PA, PB, TA and TB are connected with a hydraulic circuit, in which a hydraulic cylinder 2 for driving a ram 1, a hydraulic pump 3 and so on are set up, a so as to form a full-bridge hydraulic circuit. A compression proportional sheet valve PAp and a hydraulic pump 40 are connected as a hydraulic power source with high pressure and small flow rate parallel with the sheet valve PA being in the oil supply position side in the hydraulic circuit. An NC controller controls timing of turn-on of the proportional sheet valves PA, PB, TA and TB as well as change of the valves PA and Pap by PWM signal to pilot valves of the sheet valves PA, PB, TA and TB. The valves PA and TB are turned on in the down stroke of the ram 1, the valves PB and TA are turned on in the up stroke of the ram 1, and the valve Pap is turned on in the compression stroke.

摘要： A magnetic recording apparatus for electrocardiographs wherein an input signal is converted into a digital signal, such digital signal is accumulated and intermittently recorded, thereby enabling electric power consumption to be reduced and efficiency of use to be improved. Parallel memories are used to store the digital signal at a first rate and the digital signal is read from the memories at a second rate higher than the first rate.
