Title: Motor-driven actuator and robot
Inventor: GOTOU MINETAKA
IPC: B25J9/10
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To interrupt power transmission and reset power interruption promptly by a hardware of simple structure in case of abnormality. SOLUTION: A magnetic coupling is put between a motor 40 and a rotating shaft 42. If the force acting on the motor 40 exceeds a prescribed value, the power transmitted from the motor 40 to the rotating shaft 42 is interrupted. After that, a CPU and a PLC output an intermittent command value to the electric motor 40 to reset power transmission. When the reset of the power transmission is detected by a signal from an interruption/reset detecting device 90, the CPU and the PLC stop outputting the intermittent command value. At this time, a delicate impulse is applied as a result of the intermittent command output being applied, and the electric motor 40 is rotated in a stepped form by the impulse to reset a step-out condition.

Filed: 1985-06-05
Abstract: PURPOSE:To obtain an overflow detection circuit in which an overflow signal rises sufficiently even when the bit number of timer count is increased by providing an AND gate outputting an AND signal among the content of latch, the least significant bit and a clock pulse as the overflow signal. CONSTITUTION:When the content of the bit of the least significant digit goes to H, a P-channel transistor (TR) 9a is turned on and a potential at a contact 14a restores H at a point of time T14b and a latch 16 holds a fetched signal Q16 until a point of time T16. A signal Q20 having the same waveform as a conventional waveform is obtained by ANDing an output Q16 of the latch 16, an inverted signal phi' to the input clock phi and a signal Q1 being the content of the bit at the least significant digit. In a conventional circuit, only a half period of that of the clock signal is obtained by descending the potential at the contact 14 to L, but the potential has only to be descended during one period in this circuit and the signal is latched and the AND circuit detects overflow, then it is detected quickly and surely.
