On the other hand, a rate of imbalance in currents I1, I2 of each return wire, namely an imbalance rate, is computed in an operation circuit 6. That is, concerning currents I1, I2 of each return wire, an absolute value of a difference between them is subtracted in a subtraction circuit 7, sum of them is added in an addition circuit 8, and the absolute value of the difference is divided by the sum in a division circuit 9 to compute the imbalance rate. Whether the imbalance rate exceeds the set value or not is judged in a Schmidt circuit 10. Consequently, when the imbalance rate exceeds the set value, breakage of rail is detected.

IPC: F16H7/08
Filed: 1994-06-22
Abstract: PURPOSE:To provide an automatic tensioner which does not require a large space for installation and which can certainly prevent a belt from slackening. CONSTITUTION:The base end of a swinging member 38 is supported on a stationary shaft 37 swingably, and a pulley 43 is supported rotatably at the tip of the swinging member 38. The resilient force of a torsion coil spring 49 is given to the swinging member 38 in the rotating direction so that the pulley 43 is pressed to a belt 69. When the swinging member 38 rotates with the resilient force of the spring 49, a plunger 59 of a damper device 55 separates from a receptacle block 58 supported by the swinging member 38. Accordingly the pulley 43 is displaced quickly. When the member 38 rotates in the opposite direction, the receptacle block 58 pushes the plunger 59. In this condition, the displacing of the pulley 43 is made gradual through the action of the damper device 55.

Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To synchronously control rotating cutters by preventing interference of each of the rotating cutters without setting a master and slave relation regardless of variation of a load by reducing speed of the advancing rotating cutter detected by a deviation angle detection means and simultaneously increasing speed of the delayed rotating cutter. SOLUTION: Size of a deviation angle signal output from a deviation angle detection means 24 is adjusted to size desired to be corrected into by a correction factor adjuster 25. Thereafter, an output signal of the adjuster 25 is inversed by an inverter 26 and it is input to an inverter unit 17A as an auxiliary speed command. Additionally, simultaneously, the output signal of the adjuster 25 is straightly input to an inverter unit 17C as an auxiliary speed command. Consequently, for example, in a state where an A shaft advances against a B shaft, the deviation angle detection signal becomes a + polarity, a - polarity auxiliary speed command is input to the unit 17A, a + polarity auxiliary speed command is input to the unit 17C, and speed control is carried out so that the A shaft reduces speed and the B shaft increases it.
