Abstract

DC60 (27/09/47) When SW starter 3 is pressed down, a single shot multivibrator circuit 15 will open and a pulse is released. A pulse is sent to the self-holding circuit 16, which will continue to stay in the self-hold mode. And continuously emits H level output. Until it was reset This causes transistor 17 to open and triggers the relay to move the piston down R1. When the piston reaches the lower limit of its displacement, the lower LS 4 is open, causing the self-clamping circuit 21 to generate an H-level signal along the multivibrate output. Single-shot routers 18 H-level signals from the self-holding circuit 21 are delayed by the delay circuit 22 and transistor 23 is turned on as a result. The piston up motion relay R2 is triggered due to the function of the single-shot multivibrator circuit 15, so that the piston will not start again when the SW starter 3 is continuously pressed low. The delay circuit 22 provides the life of the winding mechanism. The choke of the throttle direction is also extended where the combination of another delay circuit 19 and the logical product circuit 24 is provided to prevent any defect caused by an impact of the lower LS 4 when SW Start 3 is pressed, a single shot multivibrator circuit 15 opens and a pulse is released.

1. The instrument control device is driven by hydraulic to drive the up and down of the Pistons in the cylinders by applying hydraulic power. Which at least consists of Lower limit measuring path to measure the lower limit of piston movement. Valve control path that responds to the measuring signal from the lower limit sensing path. To change the hydraulic oil flow acting on the piston from the downward motion to the upward motion and anti-misalignment trajectory to absorb the collision of the lower limit sensing path. This is caused by the vibration of the piston to prevent the valve control path from being wrong. The depletion caused by the collision 2.Hydraulic-driven instrument control devices as described in Clause 1, where the anti-depletion route is to prevent the breach of the valve control path. Open the direction of the impact Which consists of a logical product path Which has received the measurement signal From the lower limit measurement pathway That has been delayed at the specified time
